INSTALLATION 6

1 INSTALLATION 1.1 System recommendation

Recommended system requirements:

• Windows 2000/XP/Vista • Pentium with 2 GHz or above, 1 GB RAM or more • Graphics card supporting OpenGL

The disk space required on your hard disk can vary depending on the installation type selected.

1.2 Installation of the program and the luminaire catalogue off a DVD Please close all other programs before installing the program. Place the DVD in your DVD drive. The setup for Relux Professional ought to start automatically. If the setup routine does not start, this probably means that the “Autostart” function has been deactivated. You should open Windows Explorer, select the drive in which the Relux DVD is located and start the setup manually by double-clicking on the “start.exe” file.

INSTALLATION 7

Fig. 1—1 Starting the installation

The installation program starts with the opening screen for selecting the language. The language selected here applies for the installation only. Different languages can be selected later on when using the program and also for the program outputs. You start the installation of the main program by pressing on “Relux Professional 2007” (see Fig. 1—1).

Note If the 2006 Version is already installed on your system, you will be prompted to first uninstall the 2006 Version. The project folder, the folder with the imported LDCs and the object directory will not be deleted. After this, you must re-start the installation. Enter a new path for the 2007 Version, and your 2006 folder will not be deleted. If you need your projects from Relux Professional 2006 and the imported LDCs at a later date, you can copy these into the Relux Professional 2007 directory.

You should now select “Install Relux Professional 2007”. (See Fig. 1—2).

Fig. 1—2 Installing Relux Professional, and the licence agreement

INSTALLATION 8

You should now read the licence agreement and accept it so that you can continue with the installation. Select the country in which you are located.

Fig. 1—3 Selecting the country and installation path

In the next window, you can specify a path for the installation of Relux Professional. The default proposed for Relux is “C:\ Program Files”.

Fig. 1—4 Language settings

Once the setup routine has copied the program data, you can specify the language for the user interface, the outputs and the database. (See Fig. 1—4) You can change these settings in the program at any time. You can choose whether you install the manufacturer data locally (this is recommended if you have sufficient memory space, duration approx. 20 minutes) or whether you wish to use this data off the DVD. In the case of a network, we recommend copying the data to a network drive, so that all users can access it. You can select the manufacturers by double-clicking the tick or by using +++ or ---.

INSTALLATION 9

Fig. 1—5 Installing the luminaire data

Databases can subsequently be copied to the hard disk at any time using Relux Administrator (see ). If your project needs a luminaire from a company that is not installed on your hard disk, the program will prompt you to put the Relux Professional DVD in the drive.

Use Data from DVD drive

INSTALLATION 10

1.3 Installation of the program as a download If you do not have a Relux Professional DVD, you can download the program free-of-charge from the Relux Informatik AG homepage at www.relux.biz. Click on the Products link to take you to the product zone. Then, by pressing on the icon, you will be taken to the registration page for the download zone. You must log on with your user name and password before you can enter the download zone.

Fig. 1—6 “Products” zone webpage

If you are not yet a registered Relux user, you can register via the Please register link. You can select a user name and a password at this point. After logging on, you will be taken to the download zone where you can download the program under Relux Professional 2007. Once this file has been fully loaded, you can start the program installation by double-clicking on the file. The download version of Relux Professional contains a sample manufacturer’s database (Demo). You can either access the manufacturers’ databases online from within the program or download the desired manufacturers’ data from the download zone.

1.4 Relux Online Update Once the installation has been successfully completed, you can start Relux Professional for the first time. We recommend that you now update Relux Professional and the manufacturer databases that have been installed via the menu option Help – Online Update. Your PC needs to be connected to the Internet to do this.

INSTALLATION 11

The update manager will start and you can specify whether Relux Professional should look for updates on a regular basis. We recommend you to leave this option switched on, with a time interval of two weeks. You will then always be able to work with the latest program and database versions.

Fig. 1—7 "Update Manager" and "Relux Update" windows

Click on the Check now button. In the “Relux Update” window, you must then enter the user name and password that you selected when registering under My Relux on the Relux Informatik AG homepage. After you have entered your user data and clicked on the Update button, Relux Professional will look for updates.

INSTALLATION 12

Fig. 1—8 "Select packages" window

The “Select packages” window will open, showing you all the updates that are available for your Relux Installation. You can select each item individually for the update in order to keep down the size of the download. From Fig. 1—8 "Select packages" window you can see that a program update is available. We recommend that you always install any program updates that are available. Updates are available for the “Regent” and “TRILUX” manufacturer’s databases. The “Metalspot-Lus” manufacturer’s database is new and can be added to the existing luminaire database. You can start downloading the files that you have selected by clicking on the Update button. If Relux Professional is still open, it will then be closed. If there are projects that have not been saved, you will be prompted to save these before the update is stated.

Note By activating “save password” & “login automatically” you can have further checks for updates performed automatically, without a password.

INSTALLATION 13

1.5 Relux Administrator Relux Administrator is used to administer manufacturers’ luminaire data on an individual basis. You can decide whether you wish to install a company’s luminaire data locally or whether you will load this data off the DVD when you need it. You can also import data from companies that are not Relux members. You start Relux Administrator by selecting the menu option Extras – Relux Administrator…. Two different data sources can always be accessed for each individual manufacturer – the current DVD (or network) or a local installation on your hard disk. The header in the window shows you the source folder for your current installation. If you wish to install the luminaire data locally, please put the Relux DVD in your drive, or select the path in your network where the luminaire data is stored.

Fig. 1—9 Relux Administrator

The list of manufacturers on the DVD is read in from scratch each time the program is started and whenever the Select button is pressed (after the source folder has been confirmed). In other words, new manufacturers on future DVDs and new database versions will be displayed automatically and made available for DVD access. All manufacturers are listed in the manufacturers’ list. Two entries are possible for each manufacturer: “CD/Net” and “Local”. “Local” will only appear if you have installed one or more companies locally during installation of the RELUX program. The Show button allows you to specify which data you wish to access (DVD or local) and also allows you to hide a manufacturer during the RELUX luminaire selection. No data is deleted in this case. The company

INSTALLATION 14

remains visible in Relux Administrator and can be switched on again at any time. To install one or more manufacturers on a local basis, you should mark these in the list and select the Install Company locally button. Individual manufacturers that you have installed locally with Relux Administrator can be uninstalled again. To do this, select the entry and press the Uninstall Company button. If the company has been installed via Relux Administrator, the data will also be deleted from the hard disk. New manufacturer data that is not included on the DVD can be incorporated directly via the Add Company button. To do this, you should first copy the company’s data manually onto the hard disk and then select the company’s inf file. You can use the Import companies button to read in luminaire data from companies that are not Relux members. The light distribution curves of these luminaires must be in “EULUM”, “IES”, “TM14”, “LTLI” or “CIE” format. In the Company section of the “Import luminaires” window, the selection box will show you which companies have already been installed. All further steps relate to the company selected here. By pressing the New company button, you will open a window where you can enter a company name and the folder containing the luminaire data of the company that is not a Relux member.

INSTALLATION 15

Fig. 1—10 "Import luminaires" and "Add new company" windows

After clicking on the OK button you will see from the “Luminaires” section of the “Import luminaires” window just how many luminaire files Relux Administrator has assigned to the company that is not a Relux member and has found to be correct. You can now use the New luminaires button to import luminaires from the currently selected company. The Assign section will show the line of the LDC file from which the luminaire name and the luminaire order number are being read in. This also specifies the code system employed to interpret the lines. In the case of ANSI, the file is already written in Windows ANSI code. It will then be shown correctly in the standard Windows programs, such as Notepad. Otherwise, the relevant OEM code will be taken as a basis (generally ASCII with the standard extensions for a PC). You can adapt these values to your requirements via the Edit button. You can remove the company that is not a Relux member again by pressing the Delete Company button. If required, you can also delete the associated subfolder and all its contents.

Note If you wish to continue using the data, you must confirm this dialog with the No button.

INSTALLATION 16

1.6 Relux Vision

Fig. 1—11 Relux Vision licence

Relux Vision is automatically installed as well, in its demo mode. You can select Relux Vision materials and perform calculations with them. The outputs will, however, have a watermark added to them. You can order a program licence under the main menu option Help – Relux Vision licence. The “Licence” window will open. You can then place an online order.

Fig. 1—12 "Licence" window for Relux Vision

There is a separate manual available to Vision. You’ll find it on the DVD or on our homepage www.relux.ch.

INSTALLATION 17

1.7 New in Relux Professional 2007 These features are new in this version:

• Managing several different scenes in a single project The new multi-room feature allows you to administer all the relevant scenes in just a single Relux project. You can combine indoor areas with outdoor installations at will. The project overview keeps you informed of the all rooms that are available.

• Administering rooms and retaining an overview with the Calculation Manager and the Print Manager The new Calculation Manager helps you to retain an overview. It has a simple and clear structure and helps you plan all your light calculations in a readily manageable manner. The Print Manager has been suitably aligned for administering more than one room in a project. You can choose between individual outputs or outputs for an entire project.

• New material and texture database for optimum renderings The new database has been completely revamped and offers you a comprehensive range of the latest textures and materials (for Vision). This saves time and guarantees optimum renderings. Start your selection in the Project Manager by selecting the ‘Object’ tab and then ‘Materials / Textures’. You can now select the required textures for your project and move them by Drag & Drop onto the desired object in the 3D room.

• Contours to facilitate work on the floor plan The new program also lets you view contours on the floor plan too. This helps you when luminaries additionally have to be positioned in imported 3D buildings or outdoor installations. It also, however, makes it easier to position individual luminaires in indoor rooms.

• Undo/Redo actions Relux Professional 2007 shows you the most recent actions you have performed, which you can undo. If you wish to repeat an action that you have undone, you simply have to press on the ‘Redo’ option in the toolbar.

• Use of formulae for the X-Y-Z coordinates and angle specifications You can use formulae as positioning aids in the ‘Coordinates’ dialog box as well as in the fields with this same name in other dialog boxes.

RELUX INTERFACE 18

2 RELUX INTERFACE The Relux interface comprises four main areas:

• Main menu • Toolbars • Project manager • Action window with the individual menu

Fig. 2—1 Relux interface

You can adapt the appearance of the Relux interface to suit your requirements (you can move or switch off tool bars and hide part of the Project Manager, etc.). If you make changes that you subsequently don’t like, then you can restore the original appearance of the Relux interface by selecting the main menu option Window – Reset layout .

Not all the icons on the toolbars are active all the time. Whether an icon is active or not will depend on which object(s) have been selected (e.g. luminaire, furniture, measuring surface), the action window that is displayed or the calculations that have been performed. Non-activated icons are shown in grey. If no calculations have so far been performed, for example, the icons on the “outputs” toolbar will be grey . Some icons have an arrow in the bottom right corner. This means that there are other icons hidden behind this icon. To display all the possible icons, you must click on the icon and keep the left mouse button pressed for somewhat longer.

RELUX INTERFACE 21

The “Undo action” and “Redo action” icons have an arrow on the right. If you click on this arrow with the right mouse button, a window will appear showing all the possible actions that can be undone or redone.

Fig. 2—3 “Undo action” window

You can use the main menu option Window – Toolbars to have either individual toolbars or all the toolbars shown or hidden. Depending on whether there is a tick in the box or not, the toolbar will either be shown or not.

Fig. 2—4 Show or hide toolbars

RELUX INTERFACE 22

You can also move the toolbars and arrange them differently. You could place all the toolbars one under the other, for example. To move toolbars, you must place the cursor on the left-hand edge of the toolbar. The cursor will then change its appearance. Now select the toolbar with the left mouse button and, keeping this button pressed, drag the toolbar to the desired position.

RELUX INTERFACE 23

2.2 Project Manager You can administer your project in the Project Manager. It has tabs for “Objects”, “Projects” and “Outputs”, plus the “Coordinates” window. The “Objects” tab can be used to select luminaires, sensors, 3D objects/furniture and material/textures from databases and incorporate them in the project through Drag & Drop into the “Floor plan” or the “3D view” action window. It is also possible to select pre-defined room elements (doors, windows, skylights and pictures), basic objects (cubes, working surfaces, pillars and partition walls) and measuring elements (virtual measuring surface, reference plane for emergency lighting and escape route) and incorporate these through Drag&Drop into the “Floor plan” or “3D view”. You will find more on these individual topics in Chapters 8 Luminaires, 9 Room elements, 10 Materials and 11 Measuring elements.

Fig. 2—6 “Objects” tab

The Project Manager can be used to administer several rooms/installations in a project file. The different rooms/installations for a project are shown in the “Scenes” toolbar and can be selected there.

Fig. 2—7 Administering different scenes in a project

The “Project” tab allows you to display the objects used in the currently selected room/installation (e.g. windows, measuring elements, luminaires and the like). You can select the object types that are to be displayed. If you select All elements, all the objects will be displayed. If you select Luminaires, only

RELUX INTERFACE 24

individual luminaires will be displayed. If you have created luminaire groups in your project, you must select Groups to have these displayed.

Fig. 2—8 “Project” tab with the menu for the objects to be displayed

RELUX INTERFACE 25

The individual objects (e.g. windows, measuring elements, luminaires and the like) can be edited in different ways: The context menu for the object selected can be opened with a right click (see Fig. 2—9), or the “Properties” window can be opened with a double click (see Fig. 2—10).

More detailed information on editing objects may be found in Chapters 8 Luminaires, 9 Room elements, 10 Materials and 11 Measuring elements.

RELUX INTERFACE 26

The “Output” tab shows which output windows are open in the action window. Directories can be marked with: a red tick , i.e. all the sub-options for the directory are open a grey tick , i.e. only individual sub-options for the directory are open Sub-options can be marked with: a red tick , i.e. the sub-option is displayed as a window a blue tick , i.e. this sub-option will only be displayed in the active window until a new sub-option is selected a red monitor , i.e. the window will always be opened after the light calculation

Fig. 2—11 “Output” tab

You will find more detailed information on screen outputs in Chapter 13 Outputs. The “Coordinates” window will display the position, rotation and size (where possible, i.e. for a luminaire group, but not for a cube). The objects selected can be moved, rotated and, to some extent, have their size changed through the input of numerical values.

RELUX INTERFACE 27

Fig. 2—12 "Coordinates" window

Note The reference point of the object for the specification of the coordinates is shown in the form of crosshairs in the action window.

You can adapt the appearance and arrangement of all or part of the Project Manager to suit your requirements. All the Project Manager displays shown so far have been shown in Docking mode. Other display modes can be selected from the context menu for the Project Manager (the context menu is called up with a right click). Hide can be selected to hide the window from view. It can then be switched on again via the main menu option Window – appropriate tab (Project, Object, Output or Coordinates).

2.3 Action window The following can be displayed in the action window zone:

• Floor plan • 3D view (different views are possible) • Results output (result overview, table, isolinies representation, pseudo

colours, 3D mountain plot) • 3D luminance

The project can be edited in the “Floor plan” and “3D view” windows. The “Results output” and “3D luminance” windows are only available after the light calculation has been completed; they show the lighting engineering results. The different action windows have their individual menus at the top edge (see Fig. 2—16). The different menu options can be used to edit objects and to modify displays and window properties.

Fig. 2—16 Floor plan with context menu

In the case of the “Floor plan”, “3D view” and “3D luminance” windows, the context menu can be called up with a right click. There is no context menu for the results output. The context menu varies for the different windows. Depending on the object that has been selected, different menu options are either available for selection or are blocked (depicted in grey).

PROJECT EXAMPLES 31

3 PROJECT EXAMPLES 3.1 Relux Express

Once you have started Relux Professional, the start window containing a number of options will appear. First of all, by selecting Relux Express, you have the option of compiling a project for an interior room in a simple manner.

Fig. 3—1 Start window with Relux Express

The Relux Express function guides you through all the inputs required for an indoor room project and thus provides you with support in compiling your project. This function is particularly suitable for beginners, since it will familiarise them with the program and allow them to compile an indoor room project rapidly.

3.1.1 Project data After you have clicked on the icon, Relux Express prompts you to enter the project data. The input window is shown in Fig. 3—2.

PROJECT EXAMPLES 32

Fig. 3—2 Enter project data

Chapter 4.1 Project data explains how project data is set out on the printout.

3.1.2 Room data By clicking on the next button, you will be taken to the “Interior” window, where you can enter the necessary room parameters.

Fig. 3—3 “Interior” window

PROJECT EXAMPLES 33

In Relux Express, you can select either a “Rectangle” or the “L-Room shape” for the shape of your room. You select this by clicking on the list field. The schematic diagram of the room type shows you how the walls are arranged. In the left-hand section of the window, you can enter your own name for the room and also determine the room dimensions. This is also the point where you specify the height of the reference plane and the distance between the reference plane and the wall (offset). In the right-hand section of the window you can allocate a reflectance to each wall, the floor and the ceiling. Clicking on the “Colour” button (e.g. ) allows you to enter a reflectance directly. If, after clicking on a

button, you click on the arrow, the “Select material color” window will open. (See Fig. 3—4)

Fig. 3—4 “Select material color” window

You can select the colour of the wall directly from this window by pressing on the “Color selection” tab. In the right-hand section of the window, Relux shows you the colour selected and the composition of the colour in terms of the three primary colours (red, green, blue). Relux additionally calculates a proposal for the reflectance.

Note Only diffuse reflections are used for the calculations. The supplementary “Relux Vision” module can also perform light calculations with other materials (see the Quick Guide to "Relux Vision") which have reflecting or only partially-scattering reflection characteristics.

By clicking on the OK button, you can allocate the colour and the reflectance to the selected wall. In order to allocate a colour to the other surfaces too, it is first necessary to mark the area that has the desired colour with the mouse and then move the mouse and use it to mark the other surfaces. To do this, you should keep the left mouse button pressed and move the mouse cursor up or down.

PROJECT EXAMPLES 34

By clicking on the same material button, you can have the colour of the marked walls changed to the colour of the first wall you marked. Fig. 3—5 shows the procedure for adopting a colour on other walls.

Fig. 3—5 Assigning a colour to other walls

PROJECT EXAMPLES 35

3.1.3 Luminaire selection To be guided further through your project input in Relux Express, you must now click on the next button. This will take you to the “Luminaire selection” window, which you can see in Fig. 3—6.

Fig. 3—6 “Luminaire selection” window

You should then click on the “Luminaire selection” tab. As the next step, you can click on a luminaire company of your choice. The list under “Item number” will then show you all the luminaires from this company that are available in Relux. You can select one of the company’s luminaires by pressing on the Add button. If you wish to position several different luminaire types in the room, you can add the additional luminaires by using the Add button again. If you click on the “Luminaire type” tab, you will see all the luminaire types that you have selected. You can confirm this selection by pressing on the OK button, and Relux Express will continue with the positioning of the luminaires. There are several different approaches that can be adopted to selecting a luminaire for your project. These are explained in detail in Chapter 8.1 Luminaire selection.

PROJECT EXAMPLES 36

3.1.4 Luminaire positioning with EasyLux With EasyLux, Relux provides you with a tool that allows you to very rapidly determine the number of luminaires required for a given illuminance and have these positioned automatically. The “EasyLux” window is shown in Fig. 3—7. You should first specify the luminaire type that EasyLux is to use for the calculation. You can make your selection from among the luminaires that you have added in the previous step 3.1.3 Luminaire selection. Click on

in the “Luminaire type” section to have the list field displayed. All the luminaires that have been added will be shown here, and you can select one of them. In the “Maintenance factor” section, you can enter a maintenance factor of your choice or leave Relux to calculate this by selecting the appropriate entry from the list field. You can also click on to start the Maintenance Factor Manager so as to have the maintenance factor determined there.

Fig. 3—7 “EasyLux” window

Following this, in the “Mounting type” section, you should specify the mounting type for the luminaires from the list field. Once you have entered the illuminance required for your room, EasyLux will calculate the necessary number of luminaires and position these uniformly in the room. In the right-hand section of the window, you can change the positioning and the number of luminaires. After each change, EasyLux will re-calculate the illuminance again. This then ensures that you always have an overview of how your changes affect the illuminance. You can thus also use EasyLux to determine the illuminances for different numbers of luminaires and different luminaire arrangements. The Number of luminaires section specifies the overall number of luminaires in the room. The luminaires are always arranged symmetrically.

PROJECT EXAMPLES 37

If you specify five luminaires and the luminaires are arranged in two rows, EasyLux will use six luminaires (three luminaires in each of two rows). In the Luminaire arrangement section, you can specify that the luminaires must be arranged uniformly in the room. Alongside this, you also have three options for mounting strip lights (a 100%, 50% and 33% strip light configuration). The empty spaces will correspond precisely to the length of one or two strip lights. With Orientation of major axis, you have the option of positioning the lights longitudinally or transversally in the room. In the Number of luminaires section, you can enter two numbers to specify the number of luminaires in a row and the number of rows. By clicking on , you can switch between the floor plan and the 3D view. In the 3D view, you can rotate and move the room with the mouse so as to obtain an overview from different positions. In the 3D view, the mouse has the following functions: Left mouse button Rotates the room Middle mouse button Moves the room Rotating the mouse wheel Zooms into the room Right mouse button Context menu with the menu options

Wire frame, filled, External surfaces and axis

By clicking on the next button, you can terminate the entry of the product data and proceed to the project output.

PROJECT EXAMPLES 38

3.1.5 Project output with Relux Express You have successfully entered and calculated your Relux Express project. Relux Express then proposes a selection of outputs for the documentation of your project. You will find a detailed explanation of all the options offered by the Print Manager in Chapter 13 Outputs. What is important here is to specify the printer that you wish to use for printing out the project. (See Fig. 3—8) One attractive option is that of outputting the project directly into a pdf file. You can then send out your results by e-mail or archive them on your PC.

Fig. 3—8 Output of a Relux Express project

You can start the printing by clicking on the Print button. You can now press on the Complete button to quit Relux Express. You are now in the Relux interface, which is explained in detail in Chapter 2 Relux Interface. Finally, you must save your project under the menu option File – Save As…. As you can see from Fig. 3—9, you have to select a folder and a project name and then save the project by clicking on the Save button.

PROJECT EXAMPLES 39

Fig. 3—9 Save As

If you try to close the project without saving it first, the prompt shown in Fig. 3—10 will appear by way of a safety measure. If you click on the Yes button, the window from Fig. 3—9 will appear, and you can enter a file name and save the project.

Fig. 3—10 Safety prompt when closing the project

PROJECT EXAMPLES 40

3.2 Interior Project Once you have started Relux Professional, the start window containing a number of options will appear. You can compile new projects (Relux Express button: Interior; Projects buttons: Interior, Exterior or Road project) or open existing projects (Buttons: Open project, Recently opened or Samples)

Fig. 3—11 Start window with “Interior”

For our project, we will select the Interior Projects button.

3.2.1 Project data The “Enter project data” window will open.

Fig. 3—12 Enter project data

PROJECT EXAMPLES 41

You can enter the required data and close the window by pressing the OK button. In Chapter 4.1 Project data you will find information on how the project data is presented on the printout.

3.2.2 Room data The “Interior” window will open, allowing you to enter the required room parameters.

Fig. 3—13 “Interior” window

We will select the room name Office and the room type Polygon for our project (information on this may be found in Chapter 5.1 Room types. We enter 2.8 m for the height, and the defaults for the reference plane are adopted as they stand. We now enter the individual points of the room. For rooms with a complicated floor plan, the easiest approach is to read in the floor plan as a background image and then generate the corner points of the room. (Information on this may be found in Chapter 6.2 Importing background images). After this, the materials and colours for the floor, ceiling and walls can be specified. For the floor, for example, we press the Materials/Textures… button and select the Carpet Blue texture from the “Fabric” directory in the Relux texture library. (Information on this may be found in Chapter 10.2 Textures). For selecting the colour, you can enter a reflectance directly by clicking on the “Colour” input field (e.g. ). If, after clicking on a input field, you click on the arrow, the “Select material colour” window will open. (Information on this may be found in Chapter 5.1 Room types). It is possible to use RAL colours here.

PROJECT EXAMPLES 42

Fig. 3—14 “Select material color” with the “RAL Farbe/RAL color” tab

After the above work steps have been completed, the data shown in Fig. 3—15 should be displayed in the “Interior” window.

Fig. 3—15 "Interior" window with the data for the sample room

You can specify the room orientation with the North angle button.

PROJECT EXAMPLES 43

Fig. 3—16 Specify the North angle

After the above work steps have been completed, you can have the four overview displays presented by pressing the icon.

Fig. 3—17 Overview presentation of the sample room with a changed floor plan, wall colours and floor and ceiling textures

PROJECT EXAMPLES 44

3.2.3 Room elements (doors, windows, skylights, pictures) The room elements can now be entered as the next step. The simplest way to do this is by dragging the desired room elements onto the relevant wall or ceiling (skylights) from the Project Manager, where you should select the “Objects” tab and the “Room elements” directory. The room elements can then be edited in the “Properties” window that opens. (Information on this may be found in Chapter 9 Room elements, basic objects, 3D objects).

Fig. 3—18 "Properties" window for the windows

Please note that, in the case of windows, it is the transmittance that has to be specified and not the reflectance (as is required for walls, for example)! After windows have been entered, it is now possible to perform daylight calculations (Information on this may be found in Chapter 14 Daylight calculations).

PROJECT EXAMPLES 45

Fig. 3—19 "Properties" window for the door and picture

The room element “Picture” has had a photo allocated to it via the Material/texture button. (Information on this may be found in Chapter 10.3 Special features in picture selection).

PROJECT EXAMPLES 46

Fig. 3—20 Overview presentation of the sample room with the door, windows and picture

PROJECT EXAMPLES 47

3.2.4 Luminaire selection As the next step, the required luminaire types for the project can be selected. This is done, for example, by going to the Project Manager and selecting the “Objects” tab, the “Luminaires” directory and the Add menu option. The “Luminaire selection” window will then open, and you can select luminaires in the “Luminaire selection” tab, for example. (Information on this may be found in Chapter 8.1 Luminaire selection). The luminaire types selected for the project will be displayed in the “Luminaire type” tab.

Fig. 3—21 ”Luminaire selection” window with the “Luminaire type” tab and the luminaire types selected

3.2.5 Designing a scene Workplaces are frequently specified beforehand, so that the corresponding furniture and measuring elements can be put in position. You can select furniture from the Relux furniture library in the Project Manager by selecting the “Objects” tab, then the “3D objects/furniture” directory and the Add menu option. After this, the furniture can be incorporated in the room and edited in the “Properties” window. (Information on this may be found in Chapter 7 Positioning objects and object groups).

PROJECT EXAMPLES 48

Fig. 3—22 "Properties" window with the furniture for workplace A1

Fig. 3—23 Overview presentation of the sample room with the furniture in position

You can allocate measuring surfaces to the individual workplaces. To do this, you should select the desired table and open the context menu with a right click of the mouse. Select the menu option Define task area, and a measuring surface will be compiled. For non-rectangular 3D objects, the measuring surface will be aligned to the bounding box. You must then adapt it to the actual table surface afterwards. To do this, you can double-click the measuring surface. You will then be able to edit the measuring surface in the “Properties” window that opens.

PROJECT EXAMPLES 49

Fig. 3—24 "Properties" window with the measuring surface for workplace A1

Fig. 3—25 Overview presentation of the sample room with the measuring surfaces in position

For artificial calculations to be carried out, it is, of course, necessary for luminaires to be positioned in the room. You can drag the desired luminaire into the room from the Project Manager by going to the “Objects” tab and selecting the “Luminaires” directory. You should then double-click the luminaire, which will open the “Properties” window, allowing you to edit the luminaire. You can form luminaire groups in the Project Manager by selecting the “Project” tab, right-clicking on the luminaire to be included in the group and selecting the Group menu option from the context menu.

PROJECT EXAMPLES 50

(Information on this may be found in Chapter 7 Positioning objects and object groups and 8 Luminaires).

PROJECT EXAMPLES 51

3.2.6 Calculations When you have placed all the necessary objects in the room, you can start the light calculations via the main menu option Calculation - Calculation manager… (Information on this may be found in Chapter 12 Calculations and 14 Daylight calculations).

Fig. 3—28 "Calculation manager" window

3.2.7 Project output After the calculation, you can output the project via the main menu option Output – Print… (Information on this may be found in Chapter 13 Outputs). You can have the results output directly into a pdf file, for instance.

PROJECT EXAMPLES 52

Fig. 3—32 3D Luminance with Relux Professional and with Relux Vision – daylight and artificial light

PROJECT EXAMPLES 54

Relux Professional performs calculations with completely diffusely-reflecting surfaces. This will not produce natural pictures for reflecting materials (e.g. mirrors) or transparent materials (e.g. windows). To achieve natural pictures, you can use Relux Vision, which makes allowance for the reflection and transmission behaviour of the materials.

PROJECT EXAMPLES 55

3.2.8 Saving a project You can save the project via the menu option File – Save As … As is clear from Fig. 3—33, you must first select a directory and a project name and then save the project by clicking on the Save button.

Fig. 3—33 Save As

If you try to close the project without saving it beforehand, the prompt shown in Fig. 3—34 will appear by way of a safety measure. Once you have clicked on the Yes button, the window shown in Fig. 1—1 will appear, and you can enter a file name and save the project.

Fig. 3—34 Safety prompt when a project is closed

GENERAL PROGRAM SETTINGS 56

4 GENERAL PROGRAM SETTINGS This chapter covers the program settings that affect the entire program and/or project.

4.1 Project data The project data settings are entered via main menu option Project – Project data…. You can enter the general data for the project here: the project number, object, installation, customer, “processed by” and the date.

Fig. 4—1 The “Enter project data” window

The data on the object, installation, project number and date appear as a header on the project printouts.

Fig. 4—2 Illustration of the header lines


Comprehensive information on the project can be entered via the “Project description” window. The project description will only appear on the first page/cover sheet .

Fig. 4—3 Excerpt from the cover sheet

4.2 Enter location The data for the project location is entered via main menu option Project - Location. This data is of relevance for daylight calculations. For the location, it is possible either to select a location from the location list or to enter a new location. If a new location is to be created, the geographical longitude and latitude must be entered, together with the time zone (difference compared with UTC – Universal Time Coordinated). It is also possible to make allowance for daylight saving time (summer time) and the start and end of daylight saving time.


Fig. 4—4 “Location” window

4.3 Select language The language settings are made via main menu option Extras – Language…. User interface: Language for dialogs and input masks Output: Language in which printouts are to be compiled Database: Language for dialogs for selecting luminaries

Fig. 4—5 Language settings

Note Changes to the language settings for the user interface will only take effect after the program has been restarted.


4.4 Page setup Under Extras – Header and footer… you can position the company logo in the top right-hand corner and specify two footer lines for company data, or compile a general notice to be included on the cover sheet, all of which will appear on printouts.

Fig. 4—6 “Header and footer” window

When selecting your company logo (bmp, dib or jpg file) you must ensure that it is not too wide and does not cover up the header lines. If you wish to change the size of your logo, you can retain its original aspect ratio by specifying a size and selecting Maintain proportions.

Note The paper size, margins and portrait/landscape mode can be set by selecting main menu option File – Active window… or main menu option Output – Print… and then pressing the Page setup button. Further information on this may be found in Chapter 13 Outputs.


4.5 Options (general settings and defaults) Different program settings can be entered under main menu option Extras – Options…. General settings:

Fig. 4—7 "Options" window with the general settings

You can use US units. You can label luminaires with the luminaire type in the Control Centre and the Project Manager

Fig. 4—8 Left: default setting: no luminaire type shown; Right: luminaire type shown

As the default, you can move the entire room with the cursor keys in the “3D view” action window. By selecting the “Selected objects…” option, you can shift the selected object using the cursor keys. You can employ different 3D drivers depending on the PC that you are using.


The maximum number specified for Undo Redo determines how many steps can be undone again. Default values:

Fig. 4—9 "Options" window with the defaults

Here you can specify the values that are to be used as defaults when compiling new projects.

• Reflectances and colours for the floor, ceiling and walls etc. • Planning, reduction or maintenance factors • Height of reference plane • Distance between reference plane and wall • Maintenance factor, individually for each luminaire type


Exterior area:

Fig. 4—10 "Options" window with details of the exterior area

Here you can specify values for the wall and ceiling thickness, the reflectance of the outer walls and the q0values for the road surfaces, which are to be used as defaults when compiling a new project.


4.6 Coordinates origin/placing grid/drawing grid The fastest way of setting the coordinates origin, placing grid and drawing grid is via the icon in the “Settings” toolbar.

Fig. 4—11 “Properties” window for the coordinates origin, placing grid and drawing grid

The placing and drawing grids can be set on different values and can also be switched on and off. Frequently-used settings for the coordinates origin and the placing and drawing grids can be saved as variants and thus rapidly called up again. A new variant can be created with the icon. The icon can be used to save this variant as the default. All the different variants but one can be deleted with the icon. The coordinates origin and the placing and drawing grids can similarly be set via the menu for the “Floor plan” action window, by selecting menu option Edit – Properties or menu option Display - Origin, raster width….


Fig. 4—12 “Floor plan” action window: Edit–Properties and Display–Origin, raster width…

ROOM TYPES AND MULTI-ROOM CAPABILITY 65

5 ROOM TYPES AND MULTI-ROOM CAPABILITY

5.1 Room types For interiors, Relux Professional has the room types of “Rectangle”, “Semi-circle”, “L-room shape”, “Polygon”” Gable roof” and “Trapezoid”. For an exterior installation, Relux Professional always uses a polygonal floor space. The room types “Rectangle”, “Semi-circle”, “L-room shape” and “Trapezoid” can be subsequently converted into a polygon via the Convert into polygonal room context menu. The different room types are presented in what follows and their special features explained. The basic inputs that are the same for all room types are explained taking the example of the room type of “Rectangle”. Rectangle If you enter a new room, Relux Professional will propose the room type of “Rectangle” as the default.

Fig. 5—1 Room type: " Rectangle"

You can give the room a name in the “Room name” field. This is important if you are going to enter more than one room in a project – something which is explained in Chapter 5.2 Multi-room capability. In the preview window, you will see the selected room type of “Rectangle” and the distribution of the walls. In the “Dimensions” field, you should enter the lengths of Walls 1 and 2 and also their height. This room type is then clearly described. The room type “Rectangle” thus always produces a cube-shaped room.


For the height of the reference plane and its distance from the wall (offset), Relux Professional will always propose the default values from the Extras – Options… – Default values menu. You can adapt these values for your project. In the right-hand section of the window you can allocate a reflectance to each of the walls, the floor and the ceiling. You can enter a reflectance directly by clicking on a “Colour” input field (e.g. ). If, after clicking on an input field such as ,, you then click on the arrow, the “Select material color” window will open.

Fig. 5—2 "Select material color" window

In this window, you can select the colour of the wall directly, via the “Colour selection” tab. Relux shows you the colour selected in the right-hand section of the window, together with composition of the colour in terms of the three preliminary colours (red, green, blue), and it also calculates a proposal for the reflectance.

Note Only diffuse reflections are taken into account for the calculation. The additional "Relux Vision" module also offers a light calculation with other materials (see the Concise User Manual for "Relux Vision" on this), as well as for mirror reflecting characteristics and for reflection characteristics with only partial scatter.

You can assign the colour and the reflectance to the selected wall by clicking on the OK button. To assign a colour to the other surfaces too, you must first mark the area in the required colour with the mouse and then move the mouse and mark the other areas with it too. In doing this, you should keep the left mouse button pressed and move up and down with the mouse cursor. By clicking on the same material button, the colour of the marked walls will change to the colour of the wall you marked first.


Fig. 5—3 Assigning a colour to other walls

Fig. 5—4 Selecting a texture

You can import and edit additional textures via the Materials/textures… button. You can then allocate a texture to a wall, the floor or the ceiling in the manner shown in Assigning a colour to other walls. The precise approach is set out in more detail in Chapter 10 Materials. You can use the North angle button to specify the orientation of the room vis-à-vis North on the compass. The alignment of the room is relevant for daylight calculations. The North angle that is entered is also shown on the floor plan.


Fig. 5—5 The "North angle" window and its depiction on the floor plan


Semi-circle The sole difference compared with the room type of “Rectangle” is Wall 2, which is semi-circular. The size of Wall 4 determines the radius of Wall 2.

Fig. 5—6 Room type: "Semi-circle"


L-shaped room (L-room shape) To ensure that the L-shaped room can be precisely specified, you must enter the size of two walls (Wall 1 and Wall 6) and the lengths for “Ax” and “Ay”. “Ax” corresponds to Wall 5 and “Ay” to Wall 2.

Fig. 5—7 Room type: "L-room shape"


Polygon

Fig. 5—8 Room type: "Polygon" with a sample geometry

In the dimensions section, you simply have to enter the height here. A polygon can contain as many points as desired, and you must enter these in the “Geometry” section. You thus have to measure out the coordinates from the project plans. Wall 1 is to the right alongside Point 1. This is the next wall that follows on from Point 1 in the anticlockwise direction. The other walls are similarly next to their Points in the anticlockwise direction. There will always be the same number of walls as points. It is important for you to enter the points in an anticlockwise direction and for there to be no overlaps between the walls. You can delete marked points via the Delete button and insert a new point with the same coordinates before a marked point by pressing the Insert button.


A polygon can be created more simply via a background image. The precise approach is explained in detail in Chapter 6.2 Importing background images. Gable roof Wall 1 is always aligned longitudinally to the gable roof and Wall 2 transverse to it. “Height h” determines the height up to the point where the gable roof starts, and height “Az” the overall height of the building. It is possible to specify different colours or textures for the two sides. This is why you will find two ceilings listed in the “Geometry” section.

Fig. 5—9 Room type: "Gable roof


Trapezoid

Fig. 5—10 Room type: "Trapezoid"

The “Trapezoid” room type requires three wall lengths to be entered (Walls 1, 3 and 4). Wall 4 is at right angles to Wall 1. Walls 1 and 3 will be linked by Relux Professional, thus forming Wall 2.


Exterior installation

Fig. 5—11 Room type: "Exterior installation"

In the “Exterior installation” window, you should enter a polygon area without a height. Neither walls nor a ceiling are available. When it comes to entering the points, what has already been said under “4. Polygon” applies here once again.


5.2 Multi-room capability Relux Professional makes it possible for you to process several rooms or exterior installations in a single project. Individual rooms or exterior installations are referred to as scenes. This option is particularly attractive in conjunction with a background image, as is presented in Chapter 6.2 Importing background images. You can add a new scene to your project via the Project – Add menu or via the context menu option Add in the “Project” tab inside the Project Manager.

Fig. 5—12 Menus for multi-room capability

The window in which you can edit the room type will open. It is recommended that you enter a room name here. You can then rapidly distinguish between the different scenes in the project manager. You can assign a different North angle to each scene – something which is important for daylight calculations.


Fig. 5—13 Selecting a scene via the toolbar

You can switch between scenes either by using the toolbar or by going via the Project – Select scene menu.

Fig. 5—14 Selecting a scene via the menu

To open the window in which you can edit the room data, you should double click on the inner room perimeter and select the Project – Edit scene… menu options or press on the icon.


Fig. 5—15 Duplicating a scene

If you have to plan the lighting for several similar rooms, you can duplicate a room by selecting the Project – Duplicate scene menu option, or by selecting the “Project” tab in the Project Manager and then the Duplicate scene option in the context menu, or you can press the icon. In the next picture you can see that the “Office” scene has been duplicated. There is now a “Copy Office” scene in the Project Manager that you can edit.


You can delete the active scene via the menu option Project – Delete scene, or by selecting the “Project” tab in the Project Manager and then the Delete scene option in the context menu, or you can press the icon. You will see the currently active scene in the toolbar.

Fig. 5—16 Active scene and safety prompt

Relux Professional will issue a safety prompt asking if you really want to delete the room. There must always be at least one scene in a project. In other words, you cannot delete the last scene.

IMPORTING AND EXPORTING FLOOR PLANS AND BACKGROUND IMAGES 79

6 IMPORTING AND EXPORTING FLOOR PLANS AND BACKGROUND IMAGES

6.1 Importing floor plans in DXF and ASCII format You can import floor plans saved in DXF or ASCII via the menu option File – Import – Scene…. The floor plan that you wish to import in DXF format must fulfil the following conditions: Generate a layer with the name RELUX in your CAD (or RELUX_EXT for outdoor installations) and set this as the current layer. Capture the room by “tracing” the corner points (vertex points) of the room with a closed polyline. This is best done with the “Placing grid” activated. Save this polyline as a DXF file. You can also save the entire plan. After selecting the DXF or ASCII file, a new Relux project is opened and the file imported into this project. If no scale is given in the DXF file, you must specify a scale as shown in Fig. 6—1. Relux Professional will only generate the correct room size if the correct scale is entered.

Fig. 6—1 Scale for the DXF import


Fig. 6—2 shows an import with a scale of “1” (above) and a scale of “0.5” below.

When the room is imported with a scale of 0.5, it is twice the size in the project. If you do not know the precise scale, you should start by importing the room with a scale of “1”. You can now compare the length of a wall in the Relux project with the actual length and calculate the scale from this. For the second import, you should use the scale you have calculated, and the room will have the correct size in the Relux project. To give a clear example: If the bottom left wall in our project is really only 1.5m long and not 2m, it is necessary to enter a scale of “1.3333” (2 / 1.5 = 1.3333). If you use AutoCAD®, Relux Informatik AG can provide you with the ReluxCAD PlugIn. The luminaires can be selected from the manufacturers’ databases in an easy and user-friendly manner and are displayed true-to-scale in all individual CAD plans. Administering the luminaires used is very simple: once all the luminaires have been put in position, ReluxCAD automatically generates a precise parts list with information on all the products used in the project. The contents can displayed can be selected individually.


Fig. 6—3 An example of planning with ReluxCAD

A plan compiled in AutoCAD® can be directly transferred to the Relux Professional, Offert or Vision light calculation program at any time via a bidirectional interface. The actual light calculation, light visualisation and cost determination is then performed in Relux. The results obtained can then be sent back to the AutoCAD® planning. Optimisations and changes made in Relux Professional will be taken over automatically in the CAD planning if required. Depending on the planner’s individual requirements, the calculation results can also be displayed as tables, isolines or, quite simply, as average values for the room. Fig. 6—3 shows an example of isolux lines for the illuminance being transferred into the CAD plan. Three-dimensional buildings, façades or room geometries can also be transferred from AutoCAD® to Relux Professional, or Relux Vision, and calculated there. Conversely, it is also possible to take 3D data from the light calculation program (and hence 3D luminaires too) and use this data in AutoCAD®. You will find further information and a test version in the Internet under www.relux.biz.


6.2 Importing background images Importing a background image makes it easier to compile polygonal surfaces. There, the background image serves as a template for drawing the polygonal measuring areas. You can import a background image via the menu option File – Import – Background image… or, from within the “Floor plan” action window, by selecting Display – Background image – Add…. The image must be in WMF format (Windows Metafile). This format can be created in CAD and image processing programs.

Fig. 6—1 Processing background image

Relux Professional incorporates the background image in the floor plan. As the next step, you must specify the scale and the origin.

Fig. 6—4 Specifiying the scale for the background image

You specify the scale by zooming into the background image and looking for a known length. You should select the menu option Display – Background image – Set scale in the action window. In Fig. 6—4, for example, we know that the meeting room is 7.5m long. Click on the left-


hand corner and, keeping the mouse button pressed, drag the line to the right-hand corner and then let go of the mouse button again. The “Scale background image” window will open, in which you can enter the length of the line that you have traced. As the third step, select menu option Display – Background image – Set origin in the action window. The cursor will change into a cross. Click with this cross on the point where the room coordinates 0m; 0m are to be positioned.

Fig. 6—5 Fully adjusted background image

You can now use the background image as a template for positioning objects or measuring areas. Another possible approach involves changing the room to the size of the meeting room. You change the room by using the background image as a template again. Click on the room and you will see the corner points. Click on a point, keep the mouse button pressed, and drag it onto one of the corners of the meeting room. If necessary, you can convert a rectangular room into a polygonal room via the Convert into polygonal room context menu in the action window. After clicking on the floor plan you can add points to the polygon or remove points from it via the icons, and drag these onto the points in the background image. From inside the “Floor plan” action window, you should select the menu option Edit – Properties and then switch on the Show background image only in the room switch. The background image display will then be confined to the room.


Fig. 6—6 Entire background image and background image restricted to the room

You can use this option and the option described in Chapter 6 to process several different scenes in a single file and thus plan the entire office storey. If you duplicate the scene, you must insert the same background image again. The scale and origin will be adopted and do not have to be aligned once more. Adapt the room to a different office in the background image and repeat the process until all the rooms have been entered. You can remove the background image from the floor plan via menu option Display – Background image – Remove… in the action window.

6.3 Exporting rooms You can use the File – Export menu option to export the room in ASCII format (ReCAD) or DXF format. The room shape and room size will then be exported.

POSITIONING OBJECTS AND OBJECT GROUPS 85

7 POSITIONING OBJECTS AND OBJECT GROUPS

7.1 Positioning objects First of all, two important notes:

1. There are two steps involved in positioning single luminaires or individual room elements:

1. Allocating the position in the form of X, Y and Z coordinates, with the centre of the body being placed at the coordinate point. For all standard rooms, the zero point of the coordinate origin (x = 0; y = 0; z = 0) is in the bottom left-hand corner.

2. Rotating the body around the axes of the body. This means that a rotation always involves a change in the position (direction) of the other axes of rotation (i.e. axes of the body). The order in which the rotations are performed is thus particularly important:

1st rotation: Luminaire Z axis Room elements Z axis 2nd rotation: Luminaire C0 axis Room elements Longitudinal axis In the standard case, without rotation around the Z axis,

this will be parallel to the X axis 3rd rotation: Luminaire C90 axis Room elements Transverse axis In the standard case, without prior rotation, this will be

parallel to the Y axis

2. Collisions between individual luminaires and/or individual room elements or with

the areas delimiting the room (floor, walls and ceiling) should be avoided. A test to check for this can be performed with the icon. When performing rotations, the direction of rotation (positive or negative leading sign) is important. A positive leading sign means that the rotation is performed in the mathematically positive direction, i.e. anti-clockwise. The procedure to be adopted is also known as the right-hand rule the thumb of the right hand points in the direction of the axis of rotation (positive counting direction), and the bent fingers show the positive direction of rotation.


1st rotation 2nd rotation 3rd rotation The second and third rotations are based on the body axis as it results from the preceding rotations. There are two different versions of the “Standard” tab in the Control Centre and the “Properties” window of the individual object involved: one for rectangular elements and one for polygonal elements. We will take a virtual measuring surface as an example of a rectangular element here. The position in the room, the rotation around the body axes (see “right-hand rule”) and the dimensions are entered via the dialog.

Fig. 7—1 "Properties" window for a virtual measuring surface

A cube element will be used as an example of a polygonal element. The position is generally specified by the geometric centre point of the object; this can be aligned to the particular requirements in the “Extended” section.


Fig. 7—2 "Properties" window for the cube type – “Standard” tab

The element shapes available are • rectangular • round • polygonal

These can be changed at any time with the pull-down menu. The “Extended” section fulfils two requirements: on the one hand, the corner points are specified in relative coordinates vis-à-vis the origin (insertion point of the object) and, on the other hand, the material and reflectance data for the individual surfaces are specified.

Fig. 7—3 “Properties” window for the cube type – “Extended” tab


Note 1 The material allocation can be performed for all the surfaces of an object under the "Standard" tab or for other surfaces in the "Extended" section.

Note 2 It is also possible to have the horizontal illuminances output for all the room elements. To do this, please mark the checkbox on the far right in the "Output" column.

The insertion point of an object is generally located in the geometric centre of the rectangle enclosing the object (bounding box). For special configurations (including the user’s own elements for the furniture library), it is very helpful to redefine the insertion point. To change the insertion point, it is recommended that the object first be brought back into its starting position (e.g. positions X, Y and Z and rotations AZ, AX and AY are set on 0); the insertion point should then be reset and a check conducted in the 3D view.

Fig. 7—4 “Properties” window for the cube type - "Insertion point" tab


Specific points on the cube can be readily selected from the list:

7.1.1 Positioning objects taking the example of individual luminaires 1. Positioning a luminaire via the Project Manager:


Fig. 7—6 The Project Manager with luminaires and the “Coordinates” window

Click on the desired luminaire and move it by means of Drag&Drop into the floor plan or a 3D view. You can also call up the context menu with a right click on the luminaire and insert a luminaire at coordinates 0 m / 0 m via the Insert into room menu option. Relux Professional selects the height of the luminaire from the luminaire data. A ceiling luminaire is thus mounted on the ceiling and a suspended luminaire is suspended. If you click on the luminaire, you will see the precise position and orientation of the luminaire in the “Coordinates” window. New values can be entered and then adopted by pressing the Apply button. You can move the luminaire around the floor plan and a 3D view by means of Drag & Drop. The “Coordinates” window will show you precisely how the position of the luminaire is changing. In a 3D view you also have the option of changing the height and rotation of the luminaire by means of Drag & Drop. To do this, you must move the cursor over a coordinate axis in such a way that it becomes yellow. You can now move the luminaire in the required direction by clicking on the mouse button and keeping it pressed. Once you let go of the mouse button, the new coordinate will be shown in the “Coordinates” window.

Fig. 7—7 Moving a luminaire in a 3D view

Fig. 7—7 shows a luminaire being moved along the x axis. The designation “x 0.500” shows you that you have moved the luminaire 0.5 m along the x axis. While the luminaire is being moved, it will be set on the placing grid if


this is switched on. By pressing on the Shift key, you can switch off the placing grid for a time and move the luminaire around to the nearest millimetre.

Note The position of the cursor is shown in the status bar on the bottom right.

When you select an object and move it, the coordinates for the moved object will be shown in the status bar.

If you call up the context menu from within the action window of a 3D view by means of a right click, you can then click on the Rotate menu option.

Fig. 7—8 Rotating a luminaire in the 3D view

When you click on a luminaire, the area around the luminaire takes on a different appearance, as is shown in Fig. 7—8. To rotate the luminaire, you should follow the same procedure as for moving a luminaire. 2. Positioning a luminaire via the Insert - Luminaires menu option: This menu shows all the luminaires that you have added to your project. By clicking on a luminaire, you can have this inserted in the room at coordinates 0 m / 0 m.


3. Positioning a luminaire via the control centre: You can start the control centre by pressing the icon. Then, by pressing on the New button, the “Insert new object” window will open. You should select the Single luminaire menu option and quit the window. You are now in the “Control centre” window again and you can select the luminaire via Type and allocate it a name under Designation.

Fig. 7—9 Control centre with individual luminaire

You can specify the position, rotation or aiming point for this individual luminaire.

Aiming point


7.2 Positioning object groups There are two different types of groups in Relux:

• Object groups for linking different elements into a single unit; furniture constitutes a special sub-type of this group, which is contained in a database of its own.

• Group arrangements of a single element, e.g. a strip of luminaires. If an individual object has been selected in the Control centre, it can be arranged in different ways by means of the Group button.

Fig. 7—10 "Insert new object" window

The following options are available in the dialog – all the configurations apart from the circular and mirror arrangement are based on the standard field, and only a number of parameter prompts are different: The different group arrangements will be explained here, together with the key parameters, in order to provide an overview:


Group Brief description Group definition Field Arrangement in rows and

columns

Specification of number and spacing of the objects in two directions (rows and columns); the direction of the two axes in relation to each other can be defined.

Row Arrangement in a line

Arrangement of objects in a row (line), specification of the spacing between two elements or placing between two points.

Outline Arrangement along a wall

The objects are arranged in the direction of one of the walls in the room, at a specified distance from the wall.

Circle Arrangement as a circle or ellipse segment

All the objects are arranged around the specified central point along a circle or an ellipse. Circle or ellipse segments are similarly possible.

Uniformly Objects are arranged uniformly in rows and columns within the room.

Uniform alignment of objects, generally luminaires, within a room; the room is taken to be a rectangle with the maximum dimensions in the X and Y direction.

Mirroring An object or body is mirrored at the two orthogonal mirror axes (room axes)

Objects or object combinations are mirrored at a definable X and/or Y axis; this is the standard practice for stadium lighting.

For the “Field” arrangement, a specific explanation is given of the functions in the different tabs. Please note that for the field, row, outline and uniformly options, the first tab is always marked “Field” and the page only differs in the pre-selection of the pull-down menus for the three input sections:


Grouping with the Field grouping type

Fig. 7—11 “Control centre" window with the properties for Field

The left-hand section contains the information on the starting point for the group, the central section the number of columns in the group (number of elements in the X direction of the coordinate system) and the right-hand section the number of lines (number of elements in the Y direction of the coordinate system). The second tab "Position/Rotation" similarly contains the starting point of a configuration and, in addition to this, the specification of three angles of rotation which can be used to rotate the entire group around its axes (see "right-hand rule" at the start of this chapter). The third tab "Object arrangement" contains the angle of rotation of the individual object within the group. Details on the Field grouping type: After you have inserted an individual luminaire in the room, you should open the Control Centre with the Project – Control centre menu option or the icon. After clicking on the New button, the “Insert new object” window will open. You will find the group types that are possible under the Luminaire groups menu item.


Fig. 7—12 Control centre with "Insert new object" window

After selecting the desired group type and clicking on the OK button, the “Insert new object” window will be closed in the Control Centre and the “Properties” window for a luminaire group in a field arrangement will be displayed.

Fig. 7—13 Control centre with “Properties” window for a luminaire group in a field arrangement

What Relux proposes is a field with three luminaires in the x direction (columns) and two luminaires in the y direction (rows). You can see the

Preview window with icons for rotating, zooming and moving the object


configuration in the preview window and change the preview to suit your requirements with the three , and icons. In the left-hand section of the window, the coordinates for starting point A of the group (x=1 m / y=1 m) are given under Position. In the central section of the window, the number of luminaires in the x direction (3) and the luminaire spacing (2 m – centre point of luminaire to centre point of luminaire) is given under Distance. In the right-hand section of the window, under Distance, you can see the number of luminaires in the y direction (2) and the luminaire spacing (1.5 m – centre point of luminaire to centre point of luminaire). Fig. 7—14 shows the luminaire arrangement that would result after clicking on the OK button.

Fig. 7—14 Proposed luminaire arrangement accepted

If you wish to move the luminaire field you can do this by means of the offset, for example. In the example shown, the offset for the x and y direction is 2 m.


Fig. 7—15 Moving the luminaire field by means of the offset

The switches for Create chessboard pattern (black/white) switch off individual luminaires.

Note

By pressing the icon you can have the action window re-drawn, and the new luminaire arrangement will be visible.


Fig. 7—16 Chessboard pattern black


Fig. 7—17 Chessboard pattern white


In the right-hand section of the window, you can determine the angle between the individual rows. The default is 90°, which makes sense for most applications. In the example, the angle vis-à-vis the main axis is 45°.

Fig. 7—18 Angle to main axis 45°

Instead of an angle, you can also specify a third Point (C).


Fig. 7—1 Entering Point C


With Distance between objects you can position strips of luminaires in a simple manner (distance = 0 m).

Note The luminaire then starts at position (x=1 m / y=1 m). This is where the centre point of the luminaire was before.

Fig. 7—2 Positioning on the basis of the distance between the luminaires

In the left-hand section of the window, you can select the Start/End point option instead of the Position option. The starting point (A) and end point (B) of the group will then be specified (A: x=1 m / y=1 m; B: x=9 m / y=1 m). The Distance or Distance between objects is then no longer relevant, only Uniformly or Centred.


With Uniformly, the luminaires are placed in a uniform arrangement and the centre points of the luminaires are at the starting and end point.

Fig. 7—3 Arrangement based on starting/end point and uniformly


With Centred, the luminaires are arranged in such a way that the distance between the starting point and the centre point of the first luminaire and the distance between the centre point of the last luminaire and the end point is equal to half the luminaire spacing (from luminaire centre point to luminaire centre point) in each case. In the example: 9 m distance between the starting and end point, i.e. the luminaire spacing = 3 m (from luminaire centre point to luminaire centre point) and 1.5 m between the starting point and luminaire centre point of the first luminaire, plus 1.5 m between the luminaire centre point of the last luminaire and the end point.

Fig. 7—4 Arrangement based on starting/end point and centred


In the left-hand window section you can also specify a Wall. Its starting and end points are then starting point (A) and end point (B). An arrangement based on Uniformly no longer makes sense, because the luminaires are outside the room. It is also necessary to specify an offset so that the first row of luminaires is not up against the wall.

Fig. 7—5 Oriented to Wall 1, centred and with an offset of y = 1 m


The wall is always the main axis (A-B), which means that offset y is always the distance between the first row of luminaires and the wall.

Fig. 7—6 Oriented to Wall 2, centred and with an offset of y = 1 m


A number of examples for the grouping type Field: You want to place a group of luminaires uniformly (5x3) in the room.

Fig. 7—7 Luminaire group 5x3 positioned in a centred arrangement


You want to place three luminaire rows, each with six luminaires, in the room in a uniform arrangement.

Fig. 7—8 3 Luminaire rows arranged uniformly


You want to position one row of luminaires with three luminaires along Wall W3 at a distance of 1 m, but only over half the length of the room.

Fig. 7—9 1 Luminaire row along Wall 3 over half the width of the room


Grouping with the Row function: This works in the same way as grouping with the Field function. You cannot, however, enter a number for the number of rows in the right-hand side section, because there is only one row. Creating an object group via the context menu in the “Floor plan” action window and the Place objects in row menu option: Once you have selected an object with a click, you should open the context menu with a right click and select the Place objects in row menu option. The cursor will change into crosshairs. You can use the crosshairs to draw a line that determines the end point and the direction of the luminaire group. To do this, click on the point where the luminaire group is to end. The “Properties” window will open, and you can make further changes here (see Fig. 7—10).

Fig. 7—10 Placing an object in a row


Grouping with the Circle function:

Fig. 7—11 "Control centre" window with the properties for a circle of luminaires 1

In many cases, a circle/ellipse arrangement is not required in the form of a complete circle or ellipse. Relux offers the full range of possibilities here: by selecting "Ellipse b = small semi axis", it is possible to specify the side ratios of the ellipse. The input of a starting and ending angle means that any type of circle and ellipse segment can be obtained.

Note 1 a = big semi-axis points in the X direction

b = small semi-axis points in the Y direction

Note 2 Under the "Position/Rotation" tab, the angle of rotation "AZ/Z[°]" for ellipses can be used to set the position of the ellipse segment in relation to the coordinate axes.


Grouping with the Mirroring function:

Fig. 7—12 Control centre window with the properties for mirrored luminaires

This configuration makes it possible to adopt individual luminaires or already-grouped luminaires for illuminating an area (e.g. a sports ground) in the bottom left-hand quarter and then use these for the other three quarters of the sports ground. The specific feature of this configuration is the retention of the light distribution. If the illumination for the bottom left-hand quarter has been optimised, it is no longer necessary to perform an alignment of the individual luminaires for the other poles.


Example for the Mirroring grouping type: An installation with two tennis courts is to be illuminated with eight floodlights (4 poles with 2 floodlights each).The installation is symmetric around the x and y axes. The coordinate origin is in the centre of the installation. As the first step, you should position the individual luminaires. There are two luminaires in our example.

Fig. 7—13 Positioning the individual luminaires

You can now mirror the individual luminaires separately. Start the Control Centre via the Project – Control centre menu option or the icon. After that, you should select the luminaire that is to be mirrored. Then click


on the Group button. The “Insert new object” window will appear. You should now select the Mirroring option here, confirm your selection with the OK button and return to the properties window in the Control centre.

Fig. 7—14 Left: Mirroring grouping type; Right: Mirrored luminaire

You have to enter the mirror axes as x’ = 0 m and y’ = 0 m, because the coordinate origin is located in the centre of the tennis-court installation. You can mirror at the x’, y’ and x’/y’ axis. The following pictures show the resulting arrangements.


Fig. 7—15 Mirroring at the x' axis


Fig. 7—16 Mirroring at the y' axis


Fig. 7—19 Mirroring at the x'/y' axis

In our example, mirroring has to be performed at all three axes.


Fig. 7—20 Mirroring at the x ,y' and x'/y' axis

The second floodlight also has to be mirrored in order to complete the installation.


Fig. 7—21 Mirroring the second luminaire at the x, y' and x'/y' axis


7.3 Breaking up groups

Fig. 7—22 "Control centre" window – Break button

In the Control centre:

Fig. 7—23 Prompt for breaking up a group; right: depiction of a free group

Mark the corresponding group with the mouse and press the Break button. A window will now open in which you can break up the group entirely, into a free group, or terminate the process. If you break up the group completely, you can edit the objects individually again. If you convert the group into a free group, you can similarly edit the objects individually. The groups are still linked together as a group, however, and can thus be selected as a group in the “Floor plan” action window, for example, and moved around together.


In the Project Manager, under the “Project” tab: Open the context menu by right-clicking the desired group and then select the Break menu option. You should then continue in the same way as in the Control centre. In the “Floor plan” action window: Mark the corresponding group with the mouse. You can then either press the icon or right-click to call up the context menu and select the Break group menu option. There is no safety prompt. The group will be broken up completely straightaway, and you can edit the objects individually again.

LUMINAIRES 123

8 LUMINAIRES This chapter gives detailed information on searching for, selecting and positioning luminaires. You will be shown how you can equip the luminaire with a specific lamp type or specify a louvre from a given selection.

8.1 Luminaire selection You can select the luminaires that you wish to use in your project via the menu option Luminaires – Selection… or, from within the Project Manager, by selecting Objects – Luminaires – Add. The “Luminaire selection” window will open, and the options it contains are described in detail in this Chapter.

Fig. 8—1 The “Luminaire selection” window the first time it is called up

LUMINAIRES 124

8.1.1 The “Luminaire selection” tab The simplest way to add a luminaire to your project is via the “Luminaire selection” tab. You will find all the luminaire companies that are Relux members listed here. This data will either be on your hard disk or on the DVD, depending on the installation mode you selected. If you update Relux Professional regularly via the Help – Online Update menu option, you will always have the latest luminaires available for your project. The “Online Update” function is described in greater detail in Chapter 1.2 Installation of the program and the luminaire catalogue off a DVD. After you have clicked on the manufacturer you wish to select, all the luminaires available from this manufacturer will be shown under “Item number”. If you have not yet installed this company’s luminaire data, Relux Professional will ask you to insert the data medium in your drive. You can now select one of this company’s luminaires by scrolling down and clicking on the desired luminaire. You can then add this luminaire to your project by pressing on the Add button. (See Fig. 8—2) If you wish to position several different luminaire types in the room, you should add the additional types by clicking on the Add button again. By clicking on the Replace button, you can overwrite a luminaire that you have already selected, which is marked in the “Luminaire type” tab, with a new article number. Above the Export button, a window opens in which you can export the luminaire data for the luminaire shown in either “CIE”, “EULUM”, “IES”, “LTLI” or “TM14” format and then use it outside of Relux Professional.

Fig. 8—2 “Luminaire selection” tab – adding a luminaire

LUMINAIRES 125

Relux Professional offers you further options for the user-friendly selection of luminaires: 1. Once you have clicked on an article number, this section of the screen will be activated. You can now start entering the desired article number via the keyboard without pausing. The blue bar will come closer to your desired article number with each number or letter that you enter. No distinction is made between upper-case and lower-case letters here. 2. After clicking on the Extended search button, the “Extended search” window will open. Employing the following search criteria, you can now find one or more luminaires that fit your search criteria: a) “search in text”: searches the ordering texts b) “Search in Catalog number”: searches the article numbers (including parts of them) c) “Lamp search”: searches for luminaires on the basis of the lamp type used, the number of lamps and the lamp wattage d) “Ballast search”: searches for luminaires according to the ballast employed. You can also combine the search characteristics and thus delimit the search still further. If you know, for example, that the luminaire you are looking for has a BAP high-gloss louvre, is fitted with a 35W bulb and the article number contains a “91”, you should fill out the window in the manner shown in Fig. 8—3.

Fig. 8—3 Selecting a luminaire – Extended search

LUMINAIRES 126

Relux Professional will then find two luminaires that fit your criteria. Since you are looking for a ceiling luminaire, only luminaire “91W04.135.7” will be appropriate. You should select this with a click and add it. The Extended search (active) button shows you that only luminaires that fit the criteria you have entered are being shown. If you want all of a manufacturer’s luminaires to be shown again, you must open the “Extended search” window once again and click on the reset button. All the entries in this window will then be deleted. After you have clicked on the reset button, all the article numbers will be shown again. 3. You can also select luminaires by entering the luminaire name and the product group. You can select the luminaire name and the product group by clicking on the appropriate list field. You select the luminaire by clicking on the article number. You must then press the Add button to have the luminaire included in your project. The Luminaire name and Product group buttons with a grey background show that you have restricted the article numbers to this luminaire name or product group. If you click on the two buttons, all the article numbers will appear again.

Fig. 8—4 Selecting a luminaire via the luminaire name and product group

After selecting a luminaire, you can then select any combinations or lamp types that may be available, after clicking on the appropriate list field. You should pay particular attention to the different lamp types with different light colours and hence different luminous fluxes. For luminaire “91W04.135.7”, for example, you can change the default light colour of

LUMINAIRES 127

4000 K (neutral white) to a lamp with 6500 K (daylight white). The luminous flux employed for the calculation will then be automatically changed from 3300 lumen to 3050 lumen. The “Luminaire selection” tab also gives you a brief description of the luminaire, the light distribution curve and a picture of the light.

LUMINAIRES 128

8.1.2 The “Online” tab The “Online” tab is structured in the same way as the “Luminaire selection” tab. By contrast to the case for the “Luminaire selection” tab, however, you need to be connected up to the Internet for this. The very latest luminaire data will then be available to you, because you are directly accessing the data online at Relux. The search, selection and addition of a luminaire is performed in the same way as described in Chapter 8.1.1 The “Luminaire selection” tab .

8.1.3 The “Imported companies” tab Chapter 1.5 Installation shows you how to import luminaire data from companies that are not included in Relux Professional. In the “Company” section, you will see all the manufacturers that you have imported, with the name that you saved for them. If you click on a manufacturer, all the luminaire data that has been imported will be shown.

Fig. 8—5 "Imported Companies" tab

You can select a luminaire on the basis of the luminaire name, the luminaire number and the file name of the LDC file. If you wish to add a luminaire to your project, you must click on the Add button.

LUMINAIRES 129

8.1.4 The “Plug-In” tab In the “Plug-In” tab, you can start company catalogues and then export luminaires from there into Relux Professional. These are company-specific electronic catalogues, distributed to customers by individual Relux members, which you can install on your computer. If both installations (Relux Professional and the company-specific catalogue) recognise each other on your computer, the corresponding company entry will be made automatically in the Plug-In tab. You can also specifically load company catalogues of this type on to your computer. By clicking on the Available Plug-Ins button, your Internet browser will automatically start up and a page on www.relux.biz will open, showing you the Plug-Ins that are available. You can then download the required Plug-Ins from there and install them. After you have selected a Plug-In with a click, it will start when you click on the Start Plug-In button. To adopt the Plug-In in Relux Professional, you should look out for the Relux program icon or the “Use in Relux” menu option.

Fig. 8—6 "Plug-In" tab

LUMINAIRES 130

8.1.5 The “Sensors” tab This tab allows you to add sensors and motion detectors to your project.

Fig. 8—7 "Sensors" tab

The search, selection and insertion procedure for a sensor is the same as that set out in Chapter 8.1.1 The “Luminaire selection” tab .

LUMINAIRES 131

8.1.6 The “Individual luminaire” tab Inserting a luminaire via the “Individual luminaire” tab is a particularly suitable approach if you are rarely going to use this luminaire, or if you are only going to use it once. Importing an individual luminaire also makes sense if you have just a few items of luminaire data from a company and it would be a great deal of trouble to import this data via Relux Administrator from an outside company that is not a Relux member. After clicking on the Browse… button, the “Open” window opens. You are now in sub-directory “fremdlvk” in your Relux Professional program directory (Standard: “C:\Programs\Relux.200X\fremdlvk”).

Fig. 8—8 Individual luminaire tab with the “Open” window

You can, however, save your light distribution curves for non-Relux-member companies in any desired directory and switch to there. Here, you can select the required luminaire on the basis of the file name and click on the Open button to place the luminaire in the “Individual luminaire” tab. Here again, you must press on the Add button once more so as to be able to use the luminaire in your project. You can also follow this approach to incorporate more than one luminaire in your project. In this case, you must work through the different steps several times over.

LUMINAIRES 132

8.1.7 The “Luminaire type” tab The “Luminaire type” tab lists all the luminaires that are available for calculations in your project. To ensure that the luminaires or changes are adopted by Relux Professional, you should quit the “Luminaire selection” window by clicking on the OK button.

Fig. 8—9 "Luminaire type" tab

Once you have selected a luminaire by clicking on it, you can call up certain items of information on this luminaire and edit the luminaire data. The amount of information available will depend on the data supplied by the luminaire manufacturer in question.

LUMINAIRES 133

The different information options are listed below: Polar diagram button The light distribution curve is shown as

a polar diagram. Cone diagram button The cone diagram is displayed. You

can increase or reduce the distance from the reference plane via the and icons. You can then see how high the average illuminance is on an ellipse with a semi-axis that is also indicated.

CAD button A CAD drawing of the luminaire is shown.

Data sheet button A detailed luminaire description is output.

Photo button A picture of the luminaire is shown. Soellner button The Söllner curves for a luminaire

glare rating are output. UGR button The UGR values for a luminaire glare

rating are output. TM10 button The TM10 values for a luminaire glare

rating are output. Luminance button The luminance of the luminaire is

output for certain angles. Manufacturer button The precise address of the luminaire

manufacturer is output. Emergency lighting button You can configure the selected

luminaire for emergency lighting mode under the “Luminaire type” tab. To do this, click on the emergency lighting button and the “Configure luminaire for emergency lighting” window will open.

Here you can specify how the luminaire is to be used in the case of emergency lighting or in combination with the normal artificial lighting. You also determine the luminous flux that the light is to emit for emergency lighting mode.

LUMINAIRES 134

Fig. 8—10 “Configure luminaire for emergency lighting” window

In the section entitled “Calculate luminous flux for artificial lighting”, you can specify how the luminaire is to be switched in normal operation.

Note It is absolutely essential to observe the manufacturer’s data concerning emergency luminaires. It might be that emergency luminaires have already been measured in emergency lighting mode.

After clicking on the Planning aid… button, you can click on the Determine button to obtain an estimate of the maximum possible luminaire spacing for a given luminaire height and a minimum illuminance.

LUMINAIRES 135

Options button If you click the Options button, the window shown in Fig. 8—11 "Options" windowwill open. You can now change the lamp designation to your preferred lamp designation system or specify the default height for the cone diagram.

Fig. 8—11 "Options" window

Delete type button Deletes the luminaire highlighted in

blue. Modify type button By clicking on the Modify type button,

you can open the “Modify luminaire” window for the luminaire highlighted in blue.

Fig. 8—12 "Modify luminaire" window

LUMINAIRES 136

Note If you make changes to a luminaire, the luminaire number will be marked with a leading “!”.

In this window, you can adapt the luminaire and the lamp to suit your requirements. The correct luminous flux for a lamp is particularly important. The luminous flux forms the basis for calculations and has a decisive impact on the results. Please note that you should enter the luminous flux for just one lamp. Relux Professional will determine the overall luminous flux from the luminous flux of an individual lamp and the total number of lamps. It is conceivable for the luminous flux to be reduced manually, such as if the luminaire is to be used under extreme environmental conditions. The lamp manufacturers provide you with diagrams for this, showing you how the luminous flux changes at certain temperatures. You can also assign a colour to the lamp if you activate the Lamp colour on/off switch and press the icon. Relux Professional then takes this spectral distribution into account for the calculations. You can see from the 3D luminance view how the different lamp colours affect the result.

Fig. 8—13 Example showing lamp colours

Fig. 7—13 shows the same room twice over. The picture on the left has the “Lamp colour” option switched off. For the picture on the right, an orange bulb colour was selected. This option is particularly useful for coloured spot beams or RGB applications, because it gives you an estimate of the effect that the light will have.

LUMINAIRES 137

Fig. 8—14 Example showing how the light colour is used

In Fig. 7—14 you can see how the colour temperatures of light sources and colour filters or RGB values have been actively included in the processing and how their colour impact is visualised. If you activate the Lamp colour on/off switch without changing the colour via the icon, the light colour saved in the luminaire data will be used for the calculations.

These two screen shots show a light colour of 3000 K on the left and 4000 K on the right, depending on the lamp type that you selected during the luminaire selection.

LUMINAIRES 138

8.2 Arranging luminaires Since the positioning of luminaires, 3D objects, measuring area, room elements and basic objects is performed in a similar manner, the information on this has been summarised in Chapter 7 Positioning objects and object groups. Only the special features concerning luminaires will be explained here.

8.2.1 Aligning luminaires

Fig. 8—15 "Coordinates" window and fixing luminaire aiming points

After you have selected luminaires, the “Coordinates” window in the Project Manager also shows the … button. If you click on this button, an “Options” window will open and you can specify whether the aiming point of the luminaire is to be moved when the luminaire is moved or whether the previous aiming point is to be retained. In this way, the luminaire can be moved without changing the area that the luminaire lights up. This can be useful for a luminaire aimed a picture, for example, when the luminaire has to be moved but the picture still has to be lit up. If the option “Fix aiming points of luminaires when changing their position” is not switched on, Relux Professional will not change the rotation of the luminaire when it is moved. The alignment arrow will thus move with the light. If you want to light up a picture with a spot, it would be useful if the spot could be aligned to the middle of the picture without having to know the precise angle of rotation. This will save you the time required to establish the optimum angle of rotation by trial and error. Relux Professional offers you this possibility with the Aim luminaires… menu option that can be found in the context menu for the “Floor plan” or “3D view” action window or by pressing on the icon. After clicking on the menu option or the

LUMINAIRES 139

icon, the cursor will change into a target . You should then click on the luminaire.

Fig. 8—16 Aiming a luminaire at a picture

You can now click on any point on a wall, the floor or the ceiling. The alignment arrow will move on to this bull’s eye and rotate the luminaire in this direction.

LUMINAIRES 140

Fig. 8—17 The luminaire is aimed at the picture

In Fig. 8—17 you can see that the alignment arrow is now aimed at the picture. Once you have aimed all the luminaires, you should click on the icon again, or on the Aim luminaires… menu option in the context menu for this action window, so as to deactivate the aim luminaire mode.

ROOM ELEMENTS, BASIC OBJECTS, 3D OBJECTS 141

9 ROOM ELEMENTS, BASIC OBJECTS, 3D OBJECTS

9.1 Room elements There are four different types of room element: Door, Window, Skylight and Picture

9.1.1 Selection You can select and position all four types in different ways: In the Project Manager, under the “Objects” tab and in the “Room elements” folder and then with the mouse:

Fig. 9—1 Project Manager, "Objects" tab and "Room elements" folder


The simplest method is to drag the required object with the mouse onto the corresponding wall or into the desired room (for the skylight) – the dialog window for the additional settings will then open automatically.

Fig. 9—2 “Properties” window after positioning with the mouse

In the Project Manager under the “Project” tab:

Fig. 9—3 Context menu for the wall

You can open the context menu for the required wall or ceiling by right-clicking on it. Under the New menu option, you will see the room elements that are available. After you have selected the required room element, the relevant “Properties” window will appear. You will find details on the properties of the room elements under 9.1.3 Editing and properties of room elements.


3. With the individual icons on the “Insert” toolbar:

Fig. 9—4 "Selection" window

After selecting the required icon, the “Selection” window will open. In the case of a door, window or picture, you should select the corresponding wall or, in the case of a skylight, the ceiling. In the main menu:

Fig. 9—5 Insert room elements

After you have selected the required room element via the main menu option Insert – Room elements you should follow the same procedure as under 1. above.


9.1.2 Positioning Since the positioning of room elements works in the same or a similar way to luminaires, 3D objects, measuring elements and basic objects, information on this has been summarised in Chapter 7 Positioning objects and object groups.

9.1.3 Editing and properties of room elements Room element window:

Fig. 9—6 “Properties” window for windows

A window is described by a starting point X’/Y’ and the width/height of the window. The reference point for the coordinates is the bottom left-hand corner of the wall being observed, viewing this wall from the inside.

Note When the coordinates for the window are entered, they are not checked for correctness. Please use the floor plan and the 3D view to conduct a check. The preview window at the top right of the “Properties” window is also useful here.



Material Glass is used as the default here. Transmittance Caution! The transmittance must be

entered and not the reflectance, such as for walls and cubes, etc.; the reflectance is calculated (ignoring the absorption) as follows: reflectance[%] = 100% - transmittance[%]

Pollution factor Allows for the influence of pollution dirtying a window (Pollution attenuation factor).

Values: 1.0 corresponds to no pollution 0.9 standard value for pollution 0.7 value for highly industrialised

areas Default: 0.9 standard value Partitioning factor Allows for the influence of window

partitioning (Attenuation factor partitioning).

Values: 1.0 corresponds to no partitioning Default: 0.9 standard value In the case of a row of windows the option Multiple placement in a row is available in the bottom section of the dialog. If this option is selected, several windows of the same type will be treated as a single object. Using the Relux Vision supplementary module, it is also possible to specify the nature of the frame and the window sill.


Room element door:

Fig. 9—7 "Properties" window for doors

A door is described by a starting point X’ and a width/height. The reference point for the X’-coordinate is the bottom left-hand corner of the wall being observed, viewing this wall from the inside.

Note When the coordinates for the window are entered, they are not checked for correctness. Please use the floor plan and the 3D view to perform a check. The preview window at the top right of the “Properties” window is also useful here.

In the case of a row of doors the option Multiple placement in a row is available in the bottom section of the dialog. If this option is selected, several doors of the same type will be treated as a single object. Using the Relux Vision supplementary module, it is also possible to specify the nature of the frame.



Room element skylight:

Fig. 9—8 "Properties" window for skylights

A skylight is defined by the starting point X’, Y’ at the bottom left-hand corner and by its length and width. Contrary to the case for windows, the skylight is observed from outside of the room (see picture in top left with the coordinate axes).

Note No collision test is carried out between the inputs for the skylight data and the building surface. Please use the floor plan and the 3D view to check this. The preview at the top right of the “Properties” window is also useful here. This shows the view from inside the room up towards the ceiling (i.e. it differs from the skylight view with the coordinates)



Material Glass is used as the default here. Transmittance Caution! The transmittance must be

entered and not the reflectance, such as for walls and cubes, etc.; the reflectance is calculated (ignoring the absorption) as follows: reflectance[%] = 100% - transmittance[%]

Pollution factor Allows for the influence of pollution dirtying a window (Pollution attenuation factor ).

Values: 1.0 corresponds to no pollution 0.9 standard value for pollution 0.7 value for highly industrialised areas Default: 0.9 standard value Partitioning factor Allows for the influence of window

partitioning (Attenuation factor partitioning).

Values: 1.0 corresponds to no partitioning Default: 0.9 standard value For a row of skylights, the option Multiple placement in a row is available in the bottom section of the dialog. If this option is selected, several skylights of the same type will be treated as a single object. Using the Relux Vision supplementary module, it is also possible to specify the nature of the frame.


Room element picture:

Fig. 9—9 "Properties" window for pictures

A picture is defined by the starting point X’/Y’ at the bottom left corner and by its width and height.

Note When the coordinates are entered, they are not checked for correctness. Please use the floor plan and the 3D view to perform a check. The preview window at the top right of the “Properties” window is also useful here.

In the case of a row of pictures, the option Multiple placement in a row is available in the bottom section of the dialog. If this option is selected, several doors of the same type will be treated as a single object. Please note that it is possible to assign a texture to pictures (material assignment). This allows pictures to be assigned surfaces and thus to be displayed even more realistically. Using the Relux Vision supplementary module, it is also possible to specify the nature of the frame.



9.2 Basic objects There are four different types of basic objects: cube, working surface, pillar und partition wall

9.2.1 Selection You can select and position all four types in different ways: In the Project Manager, under the “Objects” tab and in the “Basic objects” folder:

Fig. 9—10 Project Manager, “Objects” tab and “Basic objects” folder

Click on the required object and move it by Drag & Drop to the required position on the floor plan or a 3D view. You can also right-click on the object and open the context menu and then select menu option Insert into room to insert an object into the room at coordinates 0 m/0 m. You can also insert the object at the coordinate origin by means of a double click. You will find details on the properties of the basic objects under 9.2.4 Editing and properties of basic objects.


2. With the individual icons on the “Insert” toolbar: By clicking on the individual icon, the desired basic object will be inserted in the room at coordinates 0/0. You will find details on the properties of the basic objects at 9.2.4 Editing and properties of basic objects. With the main menu:

Fig. 9—11 Inserting basic objects

After the required basic object has been selected via main menu option Insert – Basic objects, it will be entered in the room at coordinates 0 m / 0 m. You will find details concerning the properties of the basic objects under 9.2.4 Editing and properties of basic objects.

9.2.2 Positioning Since the positioning of basic elements works in the same or a similar way to luminaires, 3D objects, measuring elements and room elements, information on this has been summarised in Chapter 7 Positioning objects and object groups.


9.2.3 Drawing You can also draw cubes, working surfaces and partition walls. To do this, call up the context menu of the “Floor plan” action window and select menu option Draw object or use the “Insert” toolbar.

Fig. 9—12 Context menu of the "Floor plan" action window

After clicking on the required basic object, crosshairs will appear in the “Floor plan” action window. You can place the crosshairs on the required starting point and create this with a click. After this, you should go to the next points, one-by-one, and create these with further clicks. The connecting lines between the points will be shown in black. You must double-click the last point. The object will then be created and depicted with coloured lines. Depending on the desired accuracy of the area, it can make sense to switch off or refine the placing grid beforehand.

Note There are two basic types of objects for objects entered by drawing. Area-type objects (cube, working surface) are drawn as a closed polygon. The area drawn constitutes a reference area which can, if necessary, be extruded in the Z direction by the height that is entered.

Line-type objects (partition wall) are drawn as an open polyline. This polyline is interpreted as the median line, which is extruded in accordance with its width and height.

It is important to check the height after drawing a cube or partition wall.


9.2.4 Editing and properties of basic objects Basic object cube:

Fig. 9—13 "Properties" window for cubes

A cube can be freely dimensioned over its length, width and height. It can be positioned at any desired point in the room by specifying three angles of rotation and a central point (X, Y, Z). All the sides (the standard number is 6) are included in a calculation. A material and/or a colour can be allocated to all the sides either simultaneously or individually. Four options are available for all basic objects that are based on the “cube” type: Design object These elements are not taken into

account in the calculation of measuring elements (they are not cut out). Shading is, however, generated for the visualisation.

Column The element is converted into a pillar: - Floor space set on Z=0 - Height set at room height - Stands vertically in the room Locked Can no longer be changed or moved

via the mouse. Hidden The element is no longer shown on the

floor plan. It is, however, calculated.



In the “Extended” tab, it is possible to select the material or colour for each individual object surface and specify whether it is to be calculated (tick next to output). In the case of polygonal objects, it is possible to add corner points or delete them from the list. In the “Insertion point” tab, it is possible to set the point of insertion for the object (more on this in Chapter 7.1 Positioning objects). In the “Calculation” tab, you can enter the surfaces to be calculated and the calculation raster to be used. Basic object working surface:

Fig. 9—14 "Properties" window for working surfaces

The actual working surface is a rectangular or polygonal surface that can be positioned anywhere in the room. It is defined by means of: Rectangular area Polygonal area Centrepoint - Insertion point - Length - Any desired number of corner points - Width - Angle of rotation around 3 axes - Angle of rotation around three axes The working surface has two active sides. These sides are shown as surfaces in the 3D view. Both the illuminance values and the isolines can be shown on each of the sides. A typical working surface would be a desk or a drawing board, for example. The height of a working surface is set at 0.02 m.



Three options are available for all basic objects that are based on the “working surface” type: Design object These elements are not taken into

account in the calculation of measuring elements. (They are not cut out.) Shading is, however, generated for the visualisation.

Locked Can no longer be changed or moved via the mouse.

Hidden The element is no longer shown on the floor plan, it is, however, calculated.

In the “Extended” tab, it is possible to select the material or colour for each individual object surface and specify whether it is to be calculated (tick next to output). In the case of polygonal objects, it is possible to add corner points or delete them from the list. In the “Insertion point” tab, it is possible to set the point of insertion for the object (more on this in Chapter 7.1 Positioning objects). In the “Calculation” tab, you can enter the surfaces to be calculated and the calculation raster to be used.


Basic object pillar:

Fig. 9—15 "Properties" window for pillars

Pillars are displayed and calculated as cube elements, starting at the floor and extending up to the ceiling. They can be converted into polygonal, round or rectangular pillars in the input dialog for pillars. The side lengths can be varied as required. The minimum side length is 10 cm. Three options are available for all basic objects that are based on the “pillar” type: Design object These elements are not taken into

account in the calculation of measuring elements (they are not cut out). Shading is, however, generated for the visualisation

Locked Can no longer be changed or moved via the mouse..

Hidden The element is no longer shown on the floor plan, it is, however, calculated.

In the “Insertion point” tab, it is possible to set the point of insertion for the object (more on this in Chapter 7.1 Positioning objects). In the “Calculation” tab, you can enter the surfaces to be calculated and the calculation raster to be used .



Basic object partition wall:

Fig. 9—16 "Properties" window for partition walls

A partition wall is defined as a footprint which starts at the floor and can be of any height. The partition wall can be positioned at any desired point in the room, but always stands at right angles to the floor. The dimensions for the partition wall are entered by specifying the starting point (left) and end point (right). The partition wall is shown with a thickness of 10 cm as the default, but this can be changed in the Width dialog field. Four options are available for all basic objects based on the “partition wall” type: Design object These elements are not taken into account in the calculation of measuring elements (they are not cut out). Shading is, however, generated for the visualisation. Column The element is converted into a pillar: - Floor space set on Z=0 - Height set at room height - Stands vertically in the room Locked Can no longer be changed or moved

via the mouse. Hidden The element is no longer shown on the

floor plan. It is, however, calculated.

In the “Insertion point” tab, it is possible to set the point of insertion for the object (more on this in Chapter 7.1 Positioning objects). In the “Calculation” tab, you can enter the surfaces to be calculated and the calculation raster to be used.


9.3 Importing 3D objects You can read in 3DS, VRML and DXF files.

9.3.1 Importing 3D objects in 3DS, VRML and DXF format You can read in 3D objects in 3DS, VRML or DXF format via main menu option File – Import – 3D object….

Fig. 9—17 Main menu option File – Import -3D object… and “Open” window

After the file has been selected, the “Scaling” window will open. Here you will see the scaling factor and the size of the bounding box (a cube that the object fits into). You can change the scaling and, after you have entered this, see how the size of the bounding box and hence of the object changes. The number (amount) of triangles gives you information on the degree of detail of the object.


Fig. 9—18 "Scaling" window

The imported files are only available in the current project. After they have been imported, they are visible in the Project Manager – in the “3D objects/furniture” folder – and can now be used in the project.

Fig. 9—19 objects/furniture folder with an imported 3D object


9.3.2 Generating furniture Furniture constitutes a particular form of group. The large number of objects in the library extends from tables, chairs, cupboards and shelves via figures and plants / trees right through to vehicles. A combination of elements of this type can similarly be made up into a furniture element again. There are two prerequisites for creating a new item of furniture: 1. None of the elements may belong to another existing group 2. The point of insertion must be on the coordinate origin The user’s customised furniture is available in the form of object groups for all new projects. Method: Assemble all the elements for the new item of furniture at the coordinate origin (x=y=z) in the desired orientation. Mark all the elements at once; a) keeping the left-hand mouse button pressed, create a frame around the elements b) click on the elements individually, keeping the “Shift” button pressed Call up the context menu with the right-hand mouse button and select the “Create” furniture” command. The ‘Edit library’ dialog will open. A "Customized Objects will now appear at the end of the list, in the section on the left, showing the new furniture object as a sub-option. Enter the designation and activate the areas for which outputs are to be compiled by marking the checkbox in the corresponding line. Terminate the dialog with "OK".

Fig. 9—20 "Edit library” window


Note Highly intricate and detailed furniture is made up of a very large number of individual elements; if there is a large amount of furniture of this type, this can increase the computing time considerably. It is recommended that unnecessary areas be deleted where appropriate – even after furniture has been generated (the bottom of a cupboard, for example).

You will find two furniture libraries in the libraries folder: Standard35.blk library for the standard furniture

available in Relux Custom35.blk library for user-generated furniture


9.4 3D objects 9.4.1 Selection

After 3D objects (3DS, VRML, DXF) have been imported, they are available in the project library and can be used in the project. If you wish to insert furniture from a furniture library, you must first select the corresponding furniture so that it is available for the project. To do this, go to the Project Manager, click on the “Objects” tab and then select the Add option. The “Selection” window will then open. You can then open the Relux standard furniture library by pressing on the Standard objects button, or open the furniture library with the furniture you have compiled yourself by pressing on the Own objects button. You can also search for and open other libraries with the icon.

Fig. 9—21 Adding furniture from the library to the project

If you wish to select several items of furniture, you should press the Accept button. If you only wish to select one item of furniture, or once you have selected all the desired items of furniture, you can press on the Accept and close button. The selected items of furniture are now available in the current project and are visible in the Project Manager under the “3D objects/furniture” tab.


Fig. 9—22 3D objects/furniture folder with imported furniture

You can select and position the 3D objects and furniture in different ways: 1. In the Project Manager, under the “Objects” tab and the “3D objects/furniture” folder:

Fig. 9—23 Project Manager, “Objects” tab and "3D objects/furniture" folder

Click on the required object and move it by Drag & Drop into the required position on the floor plan or a 3D view. You can also right-click on the object and open the context menu and then select menu option Insert into room to insert an object into the room at coordinates 0 m / 0 m. You can also insert the object at the coordinate origin by means of a double click. You will find details on the properties of 3D objects/furniture under 9.4.3 Editing and properties of 3D objects.


2. With the individual icons of the “Insert” toolbar: After selecting the furniture icon, the last object in the list of 3D objects/furniture available in the project will always be positioned in the room at coordinates 0 m / 0 m (Project Manager, “Objects” tab, “3D objects/furniture” folder). To change the furniture type, you must open the properties window for this item of furniture with a double click. You can now have all the furniture that is available in the project displayed under Type; alternatively, you can select a new type from a furniture library by pressing on the icon. You will find details on the properties of 3D objects/furniture under 9.4.3 Editing and properties of 3D objects. 3. With the main menu:

Fig. 9—24 Insert 3D objects/furniture

After selecting main menu option Insert – 3D objects, you have the option of positioning one of the items of furniture that is available in the project or of going via menu option New 3D Object… to select a new type of furniture. The selected object is inserted in the room at coordinates 0 m / 0 m. You will find details on the properties of 3D objects/furniture under 9.4.3 Editing and properties of 3D objects.

9.4.2 Positioning Since the positioning of 3D objects/furniture works in the same or a similar way to luminaires, room elements, measuring elements und basic objects, information on this has been summarised in Chapter 7 Positioning objects and object groups.


9.4.3 Editing and properties of 3D objects

Fig. 9—25 "Properties" window for 3D objects/furniture

3D objects/furniture can be positioned by entering the X, Y and Z coordinates for their centre point. The rotation is performed around the point of rotation in the X/Y plane of the individual item of furniture. A scaling factor can be set for each coordinate direction. In the Type field, you can select furniture that is available in the project, or you can use the icon to select a new type from a furniture library.



There are five options available for all 3D objects/furniture: Design object These elements are not taken into

account in the calculation of measuring elements (they are not cut out). Shading is, however, generated for the visualisation.

Smooth edges Sloping lines and curves are depicted more realistically (Anti-aliasing – in order reduce the staircase effect on sloping and round lines)

Make faces double sided It makes sense to use this if a 3D object has one-sided, transparent surfaces or looks as if it incorporates holes

Locked Can no longer be changed or moved via the mouse.

Hidden The element is no longer shown on the floor plan. It is, however, calculated.

In the “Insertion Point” tab, you can specify the insertion point for the object (more explanations may be found in Chapter 7.1 Positioning objects).

MATERIALS 168

10 MATERIALS You can depict your planning on a realistic basis with the aid of materials (colours, textures and Vision materials). A material can be allocated to each individual design object or 3D object in Relux.

MATERIALS 172

You can either give the texture you have added a name or adopt the name from the library. With a right-click of the mouse, you can open the context menu. This allows you to delete materials that are not being used in the project, for example. You can also alter the properties of the texture with the Edit… button. The “Process surface picture…” window opens, with the two tabs “Reflectance (Rho)” and “Scaling”.

Fig. 10—7 "Process surface picture…" window with the "Reflectance (Rho)" tab

MATERIALS 173

Using the controllers for “Colour”, “Contrast”, “Brightness” and “Saturation” you can change the properties of the texture to suit your requirements.

Fig. 10—8 Left: Original colour; right: modified colour

MATERIALS 174

In the ”Scaling” tab, you can specify the size in which the texture is to be depicted.

Fig. 10—9 "Edit surface picture…" window with the “Scaling” tab

You can specify a length for the marked line. This is particularly useful for textures such as tiles or ceiling panels. You can then stipulate how big these are to be. You can use the mouse to go on to the picture and draw a line (red line) yourself (picture points) and then specify a length. This is especially practical for objects such as doors, where you know the dimensions.

MATERIALS 175

By pressing the OK button, you will be returned to the “Edit materials…” window and another click on the OK button will take you back to the “Properties” window.

MATERIALS 177

The appearance of the surface that you have edited will be displayed in the preview window.

Another approach is to go via the Project Manager and select the “Objects” tab. In the Materials/textures folder, you can then select the Add menu option to take you to “Select material…” and follow the procedure set out above. Here too, you can open the context menu with a right click of the mouse and delete materials that are not being used in the project, for example.

MATERIALS 180

After the picture has been selected, the properties of the picture are specified in three steps.

Fig. 10—19 "Define size of picture", "Name reflectance" and "Insert scale" windows

In step 1, you can define the size of the picture. The picture should not be too big (a maximum of 1024x1024), because this will make the Relux file unnecessarily large and take up a great deal of memory space. Steps 2 and 3 are performed as described in Section 10.2 Texture. You can now press the OK button to proceed. The “Edit materials…” window will open. You now have the same editing facilities as those described in Section 10.2 Textures.

10.4 Relux Vision materials Relux Vision is automatically installed as well (in demo mode). You can select Relux Vision materials and perform calculations with these. The outputs will, however, have a watermark added to them. You can order a program licence under the main menu option Help – Relux Vision Licence. The “Licence” window will open. You can place your online order here.

MEASURING ELEMENTS 182

11 MEASURING ELEMENTS Measuring elements are virtual measuring surfaces (which do not cause any shading) that can be used to calculate illuminances or UGR values, for example. There are four different measuring elements that you can use: Virtual measuring surface Reference plane for emergency lighting (this is only calculated for emergency lighting; in accordance with EN 1838 “Lighting Applications – Emergency Lighting” only the direct illuminance is calculated; a value must be specified for the minimum illuminance that is required) Escape route (a median line is defined, plus a maximum width of 2 m, as per EN 1838 “Lighting Applications – Emergency Lighting”; this is only calculated for emergency lighting; in accordance with EN 1838 only the direct illuminance is calculated; a value must be specified for the minimum illuminance required) Task area (as per EN 12464-1 “Lighting of work places. Indoor work places” it is possible to define a task area and assign partial surfaces and surroundings to these) All the measuring elements have an active side. It is thus important for the measuring elements to be correctly positioned/rotated. The active side is the side that points towards the room interior (points upwards) in the basic state. On the floor plan, these areas are shown with red lines and, in the 3D views, with red lines and red shading (only if the menu option Measuring surface off has not been switched on in the context menu for the “3D View” action window).


Fig. 11—1 Measuring element with the active side pointing up (left) and with the inactive side pointing up (right)

The active side is similarly shown in the preview window of the “Properties” window.

Fig. 11—2 Measuring element with the active side pointing up (left) and with the inactive side pointing up (right


11.1 Selection Relux Professional offers you several ways of selecting measuring elements. 1. Selection via the Project Manager and the “Objects” tab:

Fig. 11—3 Project Manager, "Objects" tab, and "Measuring elements" directory

Click on the desired measuring element and move it onto the floor plan or into a 3D view by means of Drag & Drop. You can also right-click the measuring element to call up the context menu and then place a measuring element in the room, at coordinates 0/0, via the menu option insert into room. You can also incorporate a measuring element with a double click. 2. Selection via the Control centre: Start the Control centre with menu options Project – Control centre… or the icon. After clicking on the New button, the “Insert new object” window will appear. You can now select the desired measuring element.


Fig. 11—4 Control centre with the “Insert new object” window

Confirm your selection by pressing the OK button, close the window and you will find yourself in the “Control centre” window again.

Fig. 11—5 Control centre with virtual measuring surface


3. Selection and insertion using the icons on the “Insert” toolbar: By clicking on the relevant icon you can position either the object centre point of the measuring element (virtual measuring surface, reference plane for emergency lighting) or the start of the escape route in the room, at coordinates x=0 m / y=0 m. Before you can position the task area you must have selected a working surface. The size and position are allocated to the working surface selected.

11.2 Positioning Since the positioning of measuring elements works in the same or a similar way as for luminaires, 3D objects, room elements and basic objects, information on this has been summarised in Chapter 7 Positioning objects and object groups. Only the special features that apply in the case of measuring elements will be explained here.

11.3 Drawing You can also draw all the measuring elements by calling up the context menu for the “Floor plan” action window and the Draw object menu option, or by going via the “Insert” toolbar

Fig. 11—6 Context menu for the “Floor plan” action window

This function is especially practical in the case of polygon surfaces that you have saved as a background image, for example (see Fig. 11—6). After clicking on the desired measuring element, crosshairs will appear in the “Floor plan” action window. You can position the crosshairs on the desired starting point and then create this by clicking on it. After this, you should go to the subsequent points, one at a time, and create these through further clicks. The line joining the points will be shown in black. You must mark the final point with a double click. Following this, the measuring element will be compiled and displayed by means of red lines. Depending on the desired accuracy of the surface, it may be advisable to turn off the dynamic placing grid beforehand or to make it finer.


Fig. 11—7 Example: traffic roundabout – polygon surfaces

For the “escape route” measuring element you must mark the median line of the escape route. The final point must be marked with a double click; the surface will then be compiled automatically with a width of 2m.

Fig. 11—8 Escape route: median line and area

Note There are two basic types of objects in the case of objects entered by drawing. Area-type objects (virtual measuring surface, reference plane for emergency lighting) are drawn as a closed polygon.

Line-type objects (escape route) are drawn as an open polyline. This polyline is interpreted as the median line of the object, which is extruded in accordance with its width.


11.4 Editing and adjusting settings You can edit measuring elements that have already been positioned by means of a double click in the “Floor plan” action window or via the “Project” tab. The “Properties” window will then open. You can also click on the desired measuring element, then open the context menu with a right-click and select the Properties… menu option.

Fig. 11—9 "Properties" window – Virtual measuring surface

Open the Control centre via the menu option Project – Control centre… or the icon. After selecting the desired measuring element, the “Properties” window will similarly appear. The Control centre has the advantage that the New, Delete, Duplicate, Group and Break buttons are also available to you – in other words, you have the possibility of administering the objects. The “Properties” window gives you access to all the settings that can be made via the different tabs for “Standard”, “Extended”, “Insertion point” and “Calculation”.

Note Depending on the object selected, not all the settings listed below will be available


In the “Standard” tab you can

• select the type (virtual measuring surface, reference plane for emergency lighting, escape route)

• allocate a name • specify the position, rotation, shape (rectangular, round or polygonal) and

size • specify the evaluation type (standard, task area or reference

plane/environment) • freeze the measuring element (the measuring element can no longer be

selected with the mouse in the “Floor plan” action window or “3D view” but only via the Control centre or via the Project manager and the “Project” tab or icon )

• hide the measuring element (the measuring element is no longer visible in the “Floor plan” action window or “3D view” and is also frozen at the same time, i.e. it can only be selected via the Control centre or via the Project manager and the “Project” tab or icon)

• specify a minimum illuminance (only for the reference plane for emergency lighting and the escape route)

• assign partial surfaces (only for the evaluation type of task area) • In the “Extended” tab you can: • change the shape (rectangular, round or polygonal) • In the “Insertion point” tab you can: • specify or move the position of the insertion point of the object


In the “Calculation” tab” you can: • edit the calculation grid (position and number of calculation points;

minimum: 3 points, maximum 100 grid points in the X and Y direction). • specify which illuminance/UGR values are to be calculated (only for the

virtual measuring surface and task area) •

Fig. 11—10 Position of the calculation grid

If you wish to change the shape of a measuring element later on, you can select the measuring element in the “Floor plan” action window and move an individual vertex (corner point) with the mouse. If you wish to change the size of the entire measuring element, you can increase or reduce the size of the object as a whole by selecting the measuring element in the “Floor plan” action window, right-clicking it to call up the context menu and then selecting the menu option Scale, or you can press the icon. The scaling direction can be defined via the menu option Scale type… or the icon, or you can have the scaling performed via a manual factor.


In addition, you can add or delete points by selecting the measuring element in the “Floor plan” or the “3D view” action window, right-clicking it to call up the context menu and then selecting the menu options Add vertex or Remove vertex; or you can use the icons in the “Edit” toolbar. To add a point, you must first select the menu option Add vertex or the

icon and place the cursor on the line to which you wish to add a new point. The line will then be displayed in red. By clicking on the desired point, you can add a new vertex (corner point). You will see this when you select the measuring element again. If you then move the cursor to the new point, the cursor will become a hand, and you can drag the point to the desired position. To remove a point, you must first select the menu option Remove vertex or the icon and place the cursor on the point that you wish to delete. The point is then displayed in red and can be removed with a click.

CALCULATIONS 192

12 CALCULATIONS 12.1 Calculation manager

After you have created a room and positioned luminaires, you can start a calculation via the Calculation Manager. You can specify all the different parameters for the calculation via the Calculation Manager. To start the Calculation Manager you should either select the Calculation – Calculation manager… menu option or press the icon.

Fig. 12—1 Calculation manager

In the left-hand section of the window, Relux Professional sets out all the possible calculation variants for the project. The switches for those calculation options that are not possible are highlighted in grey and cannot be switched on. If you have created a room without windows or skylights, only the Artificial Light switch will be activated. If the Save results after calculation switch is on, Relux Professional will save the project automatically once the calculation has been completed. This means you don’t have to remain at your PC while lengthy calculations are being performed, and you can still be sure that the results of the calculation will be saved. The title in the right-hand section of the window shows the room and calculation variant that you are entering the settings for. After you have clicked on the Start button, Relux Professional will start the calculation. To save your settings and quit the window, you should press the Close button.

CALCULATIONS 193

In Fig. 12—2 you will see the calculation variants for the same room, i.e. the “Office”, with windows added to it. Relux Professional recognises the possibility of an additional daylight calculation and allows you to select this via the switches. The tabs shown will change according to the calculation variant selected.

Fig. 12—2 Calculation variants with windows in the room

Fig. 12—3 shows a project with several rooms. By selecting unambiguous room names you will always know which room you are entering settings and performing calculations for. The multi-room capability of Relux Professional is described in greater detail in Chapter 5.2 Multi-room capability. An escape route has been set for the meeting room and the luminaires for emergency lighting mode switched on, which means you can also select “emergency lighting” here. In this way, you can select different calculation variants for each individual room and have them all calculated at once.

Fig. 12—3 Calculating a multi-room project

The individual calculation variants are explained in the chapters that follow. Since the setting options are the same for the individual variants in some cases, these are set out at the end of the “Artificial light” calculation variant, and only the specific differences are then explained for the other variants.

CALCULATIONS 194

12.2 “Artificial light” calculation variant 12.2.1 “Calculation” tab

In the “Precision” section, Relux Professional provides a recommendation that is suitably adapted to the room and the luminaires used in it. The recommendation will ensure that sufficiently accurate calculation results are achieved and that the computing time is optimised. As the indirect fraction increases, Relux Professional increases the number of interreflections in the calculation. The most accurate results are achieved by selecting a “High indirect fraction”. The computing time will then also be increased, however. We generally recommend you to adopt the proposed accuracy.

Fig. 12—4 Setting the accuracy

As soon as reflecting objects such as walls and a ceiling are available, you should just use the “only direct fraction” option for a rough calculation or a control calculation. The “only direct fraction” option can, however, be selected for exterior installations, such as football pitches.

Note If the “only direct fraction” accuracy level is selected for an indoor room this will not produce any results of relevance for the lighting planning! The printouts are thus marked to this effect.

The settings in the “Raster” section also have an impact on the calculation accuracy and the computing time. We thus recommend that you adopt the default settings.

Fig. 12—5 Setting the raster spacing

After clicking on the Extended>> button, you will see the setting options for the raster spacing. The raster spacing that you can change here relates to the room surfaces and the surfaces of the design elements. The raster spacing for the measuring areas is set in the measuring surfaces tab, via the Project Manager or the Control Centre (Chapter 11 Measuring elements). The Activate dynamic raster switch is used to switch on the dynamic rastering. Here, the program establishes (in the course of the calculation)

CALCULATIONS 195

the luminous fluxes and illuminance gradients that are being processed. The program then works out which surfaces need to have additional raster points incorporated on them. The dynamic raster can be set anywhere between “coarse”, “medium” and “fine” using the slide controller.

Note The computing time is influenced to a major extent by this setting. The finer the raster-point monitoring is to be, the longer the computing time that will be required for this.

In the “Maintenance factor” section you can enter a maintenance factor manually under the “classical” option, and this will be valid for the entire project. You can enter a reason for your choice by pressing the Reason… button.

Fig. 12—6 Specifying the maintenance factor

You can also have the maintenance factor determined for each individual luminaire type via the “EN12464” option, with the detailed specification of the maintenance factor, as required by Standard EN 12464. To do this, you should click on the EN12464… button, and the assistant for specifying the maintenance factor will open. In Fig. 12—7 you can see that the data for the room, the luminaires and the lamps has to be entered into the assistant. Relux Professional uses this data to calculate the maintenance factor for the particular lighting situation and the selected luminaire type. You can enter a general note for each luminaire type in a text box. This data will be output in the maintenance plan.

CALCULATIONS 196

Fig. 12—7 Assistant for specifying the maintenance factor

Note The maintenance factor is established using standardised data based on:

1. CIE Publication 'Maintenance of indoor electric lighting systems', version 2005, 1995 (marked as 'CIE')

2. ZVEI Publication 'Lebensdauerverhalten von Entladungslampen für Beleuchtung' (Service life behaviour of discharge lamps for lighting), version November 2005 (marked as 'ZVEI')

3. Philips OEM Catalogue 2003/4 (marked as 'Philips').

More recent lamp types from the individual manufacturers may differ from these.

After activating the Maintenance factor manually switch you can enter a maintenance factor manually for each luminaire type, by adjusting the value in the “Maintenance factor luminaire” field. A “Maintenance factor luminaire” box highlighted in yellow shows you that Relux Professional has calculated the maintenance factor automatically on the basis of your inputs for the room, luminaire and lamp. If the Maintenance factor manually switch is switched on, the “Maintenance factor luminaire” will be white to show that you have entered the maintenance factor manually.

CALCULATIONS 197

Fig. 12—8 Miscellaneous settings

In the “Miscellaneous” section, you can determine whether the body of the light is to be taken into account for the calculation and can thus cast shadows on other objects.

Note If luminaires are fitted some distance into the building structure (i.e. if they are mounted behind a suspended ceiling or in a concrete recess) it is important to activate the luminaire shadows, because there will otherwise be excessive deviations in the results.

The Calculate external faces switch makes it possible to include the external faces of the walls and the ceiling in the calculation. If you activate the Show selected results automatically switch, then, once the calculation is finished, the results that are marked with in the “Output” tab in the Project Manager will be opened.

CALCULATIONS 198

12.3 “Measuring areas” tab You can use the “Measuring areas” tab to specify what is to be calculated for each individual area and which calculation raster is to be used. Fig. 12—9 shows a summary of all the areas for which calculations can be performed.

Fig. 12—9 The “Measuring areas” tab

For the fields with a white background, only the horizontal illuminance is calculated at present, and you can make entries in these fields. You can enter the number of calculation points for the x direction and the y direction via “x” and “y”. Alternatively, you can also specify the desired spacing of the calculation points via “dx” and “dy”. If you enter a number of calculation points, the corresponding spacing will be indicated automatically. When a spacing is entered, Relux Professional takes the next possible number and determines the precise spacing from this. Several different calculation types are already specified for the fields highlighted in grey. No entries can be made in these fields.

CALCULATIONS 199

The “Calculation parameters” window is opened by pressing on the button

Fig. 12—10 "Calculation parameters" window

You can use the switches to activate the calculation for the corresponding illuminance or for the UGR method and to set the raster and the height for the calculation. For the vertical and semi-cylindrical illuminance you can select the direction in which the calculation is to be performed. You can add additional directions with the button. For the camera illuminance, you should enter the position of a camera. You can add more cameras by pressing on the button.

CALCULATIONS 200

The half raster width distance to the edge switch lets you specify that the first calculation point should start at a distance equivalent to half the raster width. (See Fig. 12—11)

Fig. 12—11 first: calculation points on the edge; then: first calculation point half a raster

The Do not calculate measuring points inside objects switch can be used to ensure that these calculation points are not included in the calculation of the average illuminances and uniformities. You can then prevent the results from being distorted by objects. If you wish to assign the same raster to several measuring surfaces, you can do this rapidly by means of the Synchronize selected lines button.

CALCULATIONS 201

12.3.1 “Glare rating” tab In the “Glare rating” tab, you can enter observers for whom a glare rating will be performed. Relux Professional uses the UGR method for indoor rooms and the GR method for outdoor rooms.

Fig. 12—12 "Glare rating" tab

You can add an observer by clicking on the icon and delete a selected observer by clicking on the icon. Entering a designation will make it easier for you to identify the observers on the floor plan. In the “Number of observers” section, you can control the animation of the selected observer. The slide controller allows you to set how rapidly the sightline zone should be depicted for the animation. This then allows you to control both the position and the sightline of the observer.

CALCULATIONS 202

12.4 “Daylight” calculation variant The subject of “Daylight” is covered in detail in Chapter 14 Daylight calculations and you will find the required settings for the calculation in Chapter 14.8 Daylight calculations.

12.5 “Artificial and daylight” calculation variant The setting options for both variants are combined in the “Artificial and daylight” calculation variant.

12.6 “Emergency lighting” calculation variant The following conditions must be fulfilled in order to perform an emergency lighting calculation: The emergency lighting option must be activated for the luminaire type in question in the luminaire selection under the “Luminaire type” tab (See 8.1.7 The “Luminaire type” tab, Section: Emergency lighting button) The “emergency lighting on/off” must be activated for a luminaire positioned in the room.

Fig. 12—13 Activating emergency lighting for a luminaire

In Fig. 12—13 all the luminaires are activated in the emergency lighting field. If you wish to activate individual luminaires, you must break up the luminaire group and activate the desired luminaires via the escape route, for example.

CALCULATIONS 203

A reference plane for emergency lighting or an escape route must be positioned in the room. You can enter a separate reduction factor for the emergency lighting in the “Calculation” tab. Relux Professional will perform an emergency lighting calculation with the activated luminaires and the specific light flow for emergency lighting on the reference plane for emergency lighting and escape routes.

12.7 “Sensors” calculation variant Relux Professional can calculate the detection range for sensors for purposes of presence detection. To do this, a positioned sensor must be activated in the manner shown in Fig. 12—14.

Fig. 12—14 Activating the sensor for calculations

CALCULATIONS 204

Fig. 12—15 Output of a sensor’s detection range

This output in Fig. 12—15 shows the detection range of the sensor in pseudo colours, on the basis of its characteristics, as follows: light green area: detection of the tangential direction of motion (the person moves in a circle around the sensor � easy for the sensor to detect) green area: detection of the tangential direction of motion (the person moves towards the sensor � difficult for the sensor to detect) blue area: detects very small movements (person only moves slightly (presence) � very difficult for the sensor to detect) grey area: no persons can be detected here (obstacles, distance too great)

12.8 “Solar altitude graph” calculation variant This calculation variant is closely associated with the subject of daylight and is covered in more detail in Chapter 14.8.2 Solar altitude graph.

CALCULATIONS 205

12.9 Calculating the luminous intensity for observers The Calculation – Luminous intensity menu gives you the option of determining the luminous intensity of each luminaire that is emitted in the direction of the observer.

Fig. 12—16 Determining the luminous intensity

By clicking on the icon, you can add an observer. You can delete a selected observer with a click on the icon. If there are a large number of luminaires in a room, it is advisable to restrict the list via the Limit list button on the basis of the minimum luminous intensity and the number of lights that are output.

OUTPUTS 206

13 OUTPUTS Project data and calculation results can be output on the screen, printed out or compiled in the form of a pdf document.

13.1 Screen outputs The outputs appear in the action window. All the possible outputs are listed under the “Output” tab. Possible outputs means that the Luminaire data folder, for instance, will only appear in the folder tree if a luminaire has already been selected, and the Calculation results folder will only appear if a calculation has been performed. Apart from this, the user can see which output windows are open in the action window. Folders can be marked with: a red tick , i.e. all the sub-options of the folder are open a grey tick , i.e. only individual sub-options of the folder are open Sub-options can be marked with: a red tick , i.e. the sub-option will be shown as a window a blue tick , i.e. this sub-option will only be displayed in the active window until a new sub-option is selected a red monitor , i.e. the window is always open after the light calculation. First of all, you must open the corresponding output window by clicking on the monitor or the name. Following this, you can select the Edit – Open after calculation menu option in the results output window, and the monitor will go red . It is not necessary for there to be a tick in the monitor. Another way to make this setting is to go via the template manager. You will find more on this in Chapter 13.4 Print manager.

13.4 Print manager Another possibility for producing a printout is to go via the print manager. This is called up via the Output – Print… main menu option.

Fig. 13—19 The “Print manager” window

The Print Manager summarises all the data from the Project Manager (“Output” tab) and the “Page preview” window in a single window. It also gives the user access to the Template manager. The left-hand section of the window shows the available outputs, the central section, the selected outputs, and the right-hand section the print preview. Select the outputs you require from amongst the available outputs in the left section of the window. When you click on the printer symbol prior to the output, a red tick will be added to it for the output and the output will be placed in the current print outputs (central section of the window). If entire folders are to be output, this can be done by clicking on the printer symbol for the folder. A red tick is then assigned to the folder and all the sub-options. If only parts of a folder are to be output, it is first necessary to open the folder. You can then select the required output by means of a click on the printer symbol. The folder will then be marked with a grey tick , meaning that only parts of the folder will be output. If you had already marked outputs in the project beforehand, these can be adopted by pressing on the Add to printjob button under “Open screen outputs”. If this function has already been implemented or if all the windows are already contained in the current output, the Add to printjob button will not be displayed.

DAYLIGHT CALCULATIONS 226

14 DAYLIGHT CALCULATIONS 14.1 Entering the project location

The project location is entered via main menu option: Project - Location. A location can either be selected from the location list, or a new location entered. To register a new location, it is necessary to enter the geographic longitude and latitude and the time zone (difference compared with UTC – Universal Time Coordinated). It is also possible to make allowance for daylight saving time (summer time) and enter the start and end of daylight saving time.

Fig. 14—1 “Location” window


14.2 Entering the North angle When you enter a new scene, you can also enter the North angle in the “Interior” window or the “Exterior installation” window. You can also enter the North angle later on via the Project Manager by selecting the “Project” tab and double clicking on Room structure, or by using the or icon.

Fig. 14—2 Entering the North angle

You can use the North angle button to specify the orientation of the room compared with geographic north. The orientation of the room is important for daylight calculations. The North angle that is entered is also shown on the floor plan for each room separately. An example for a North angle of 30° is set out in Fig. 14—3.

Fig. 14—3 "North angle" window and depiction on the floor plan


14.3 Options: “Exterior area” tab By going via the main menu option Extras – Options… - Exterior area you can make the program settings for exterior areas (outdoor installations).

Fig. 14—4 "Options" window for the exterior area

These settings are only relevant for the daylight and sun calculations. The thickness of the walls is necessary to ensure the correct calculation of daylight/insolation, so that allowance can be made for niches in the wall. The thickness of the ceiling is necessary to ensure the correct calculation of daylight/insolation, so that the influence of openings in the ceiling can be taken into account.

14.4 Canopy You can enter a canopy in the Control centre. To start the Control centre, select menu option Project – Control centre or the icon. Following this, select the New button. The “Insert new object” window will open. Here you should select the Canopy menu option and confirm it with the OK button, which will take you back to the Properties window in the Control centre.


Fig. 14—5 Control centre with the "Insert new object" window

Fig. 14—6 Control centre with the Properties window for a canopy

A canopy is defined as a surface that is attached horizontally to a wall. The starting point x' can be established by looking at the wall in question from the outside and from the front. The starting point x’ is then calculated from the left-hand outermost corner (including the wall thickness). The canopy reduces the impact of daylight in the indoor room, as well as the insolation. The canopy is taken into account for calculating the lighting


in the room. The "Extended" tab corresponds to the one for a cube object. It is also possible to subsequently change the associated wall that goes with the canopy here. The sides can be assigned different materials, textures and colours. The desired surfaces can be marked for the calculation outputs.

Fig. 14—7 Room with a canopy – floor plan and exterior view

The 3D exterior view can be called up via the context menu of the “3D view” action window by selecting the Exterior view menu option (see Fig. 14—8).


Fig. 14—8 Context menu for the "3D view" action window with the "Exterior view" menu option

14.5 External obstructions External obstructions reduce the impact of daylight in an indoor room as well as the insolation. If there are obstructions in the surroundings, these must be entered for daylight calculations. You can use the basic object of “Cube” here. You will find more about the basic object “Cube” in Chapter 9.2 Basic objects.

Fig. 14—9 3D Exterior view showing obstructions (made up from cubes

The 3D exterior view can be called up via the context menu for the “3D view” action window by selecting the Exterior view menu option (see Fig. 14—8).


14.6 Sky models Clear sky to CIE Only the sky radiance, without the

radiation from the sun is taken into account here. CIE Publication No. 22 of 1973 (Relux: for calculations with sun)

Overcast sky to CIE The CIE defines an overcast sky with non-uniform light distribution which differs slightly from DIN 5034 Part 2. CIE Publication No. 22 of 1973

14.7 Daylight factor The daylight factor in an indoor room with a diffuse sky state to DIN 5034 is calculated as follows:

Note

a

iEED •= %100

D Daylight factor in percent

Ei Horizontal illuminance in lux at a point inside the room

Ea Horizontal illuminance in lux outdoors, with a uniformly overcast sky

Apart from the daylight factor, the program also calculates the resultant illuminance for the uniformly overcast sky to DIN 5034. To ensure that this data can be correctly calculated by the program, it is important for the location and the times of day and the times of the year to be entered accurately. The North angle does not play any role in the calculation, since the sky is assumed to be rotationally symmetric. These results are similarly influenced by other factors, such as obstructions through other buildings, a building’s own shadows and data on daylight openings. Since, with a uniformly overcast sky, the illuminance in the indoor room always changes in proportion to the outdoor illuminance, once the daylight factor has been calculated, this is independent of the time of day and time of year and can be taken as a basis for further work with daylight.


14.8 Daylight calculations Daylight calculations can be started by selecting main menu option Calculation – Calculation manager… or going via the icon.

Fig. 14—10 Calculation – Calculation manager… main menu option

In the “Calculation manager” window that then opens, you can choose between a Daylight calculation or a Solar altitude graph. It is also possible to opt for Artificial and daylight. You will find further details on this in Chapter 12.

14.8.1 Daylight There are three tabs for the Daylight calculation.

Fig. 14—11 Calculation manager with the "Calculation" tab

Under the “Calculation” tab, you can select the calculation precision, the raster, the sky model and the options listed under Miscellaneous. In the top section of this tab, you can set the desired precision (number of interreflections).


The dialog shows four different settings: only direct fraction This should only be used for rough calculations or control calculations. The results of the direct calculation can be viewed on the screen. If they are printed out, they will have a bar running at an angle over the page with the words “direct part only”. low indirect fraction This is used for directly-radiating luminaires, or if the interreflections of the walls do not contribute very much to the illuminances on the reference plane, e.g. big halls, rooms with large window surfaces, or low reflectances at the walls. This should only be used as a trial calculation for daylight calculations. average indirect fraction Average calculation accuracy for luminaires with a low indirect component or big halls without a great deal of wall surface. This is the standard mode for daylight calculations. high indirect fraction The best level of precision, calculating a high number of interreflections; specially intended for luminaires with a higher indirect component. This calculation mode requires the most computing time but also offers the most accurate results. The central section contains the setting for the raster interval on the room surfaces and the surfaces of the structural elements. The raster intervals for the measuring areas are set in the “Measuring areas” tab or in the Properties window for the measuring areas. You will find more details on this in Chapter 11.4. You can also switch on a "dynamic raster" in order to improve the results. This means that the program will work out the luminous fluxes and illuminance gradients while the calculation is progressing. The program then works out from this which areas need to have additional raster points inserted on them.

Note The calculation time is influenced to a major extent by this setting. The finer this verification, the longer the computing time that will be required.

In the third section, the sky is selected: - overcast sky according to CIE - clear sky according to CIE (with sun)


In the “Measuring areas” tab, you can enter the calculation parameters for the measuring surfaces in the project. You will find more on this subject in Chapter 11.4.

Fig. 14—12 Calculation manager with the "Measuring areas" tab and the "Calculation parameters" window

In the “Date” tab, you still have to enter a date and a time of day so that the solar altitude can be determined, together with the resultant luminance in the sky. In addition to this, you can enter the project location and the North angle.


Fig. 14—13 Calculation manager with the "Date" tab

Note The local time can be entered for the time. The true local time required for the calculation is calculated on the basis of the location.

If the illuminances – only the daylight component – are to be calculated inside a room, it is also possible to establish the daylight factor from this. The daylight factor can then also be output for the measuring surfaces. The daylight factor is required for the “Daylight” economic efficiency calculation. You will find more details on this in Chapter 15.1. You can start the calculation by pressing the Start button.


14.8.2 Solar altitude graph The solar altitude graph shows the period of the year during which direct sunlight reaches a specific point in the room. The sky model taken as a basis here is a clear sky.

Fig. 14—14 Solar altitude graph

On the matrix-like pattern of the solar altitude graph, the virtually horizontal lines represent the month curves. The shortest line is for 21.12. The date changes for the first six months of the year, from the top downwards, to 21.01, 21.02, 21.03, 21.04, 21.05 and 21.06. The data for the second six months of the year then follows the opposite course, which means that the solar altitudes in the sky are repeated for the second half of the year. The curves for 21 March and 21 September are thus identical. The curved vertical lines show the times of day. The areas shaded in light yellow show the time of year and time of day when direct sunlight falls on the previously-defined point. The solar altitude can be precisely calculated for each individual point on the Earth’s surface and for each point in time. The height and azimuth of the sun can thus also be read off the picture provided.


Note For this calculation, it is mandatory to ensure the correct North angle and also the degrees of latitude and longitude for the building’s location.

Fig. 14—15 Calculating the solar altitude graph

A point in the room must be specified for the calculation. The calculation is then started by pressing the Start button.

14.9 Efficiency Daylight You will find information on the economic efficiency calculation for a daylight-based lighting control system in Chapter 15.1.

ECONOMICS 239

15 ECONOMICS You can perform economic efficiency calculations for daylight or artificial light via main menu option Calculation – Economics - ….

Fig. 15—1 Options for economic efficiency calculations

15.1 Economics: Daylight The main menu option Calculation – Economics - Daylight is used to perform an economic efficiency calculation for the use of daylight-controlled systems. This section of the program determines the monthly or annual percentage share of time for which daylight (using a defined daylight factor that has been determined beforehand in a daylight calculation) is sufficient to illuminate the workplace with a specified illuminance.

Note

a

iEED •= %100

D Daylight factor as a percentage

Ei Horizontal illuminance in lux at a point inside the room

Ea Horizontal illuminance in lux outdoors with a uniformly overcast sky

The calculation is performed on the basis of horizontal illuminances to DIN 5034 taking the two sky states of “overcast sky” and “clear sky” From these two extreme sky states, the so-called “average sky” is determined, which is calculated from the percentage shares (sun probabilityof the two sky states. If there are no details of the sky states at a selected location, the clear sky component can be taken to be 40% and the overcast sky component 60% (DIN 5034). This all-in assumption, however, rates the winter months too

ECONOMICS 240

highly, since these months generally have 20-30% clear sky, and it also underrates the summer months. The sun probability for Basel is saved in the tables and should form the basis for all calculations. To ensure that the calculation is as accurate as possible, only those times for which the office is actually used are taken into account. For this reason, the program only makes allowance for working days (Monday - Friday). If necessary, the staff breaks, holiday periods and public holidays can also be taken into account. The following steps are necessary for calculating the economic efficiency for daylight: 1. Defaults

Fig. 15—2 "Defaults" window

Start and end of the working day: - The time must be entered in the format shown (e.g. 8:00) Staff breaks: - Three staff breaks can be entered Holiday periods: - Three holiday periods are possible, specifying the start and end of the holiday Format: dd.mm.(yyyy) - Daylight saving time (summer time): The calculation can be performed with daylight saving time if required. - Illuminance data: For calculating the percentage share of daylight in the overall lighting, it is necessary to have the lighting engineering data for the daylight factor (in %) – determined by means of the daylight calculation beforehand – and the required illuminance (in lux) at the workplace.

ECONOMICS 241

The average daylight factor is generally obtained from the detection range of a daylight sensor that controls the system. You must decide on a location for one or more sensors and conduct a daylight calculation so that you can enter the value here.

Note The geographical data (location, degree of longitude and latitude) and the project data will be taken from the current project.

2. Sun probability

Fig. 15—3 "Sun probability” window

In this window, the sun probabilities for determining the average sky are selected. The DIN Standard makes provision for a breakdown into 40% clear sky and 60% overcast sky, i.e. 40 will be entered for all the months if the DIN Standard button is pressed. It is also possible for you to enter your own values for each month, e.g. those taken from DIN 4710 for eight German cities. If you enter your own values for your project location, you will receive an additional button (in the Figure, this is Basel, for example).
