Overview
• BIM (Building Information Modelling)
− A process of generating and managing building data during its life cycle. It can use three-dimensional, real-time, dynamic building modelling software to increase productivity in building design, construction and maintenance period.
− “ A model-based technology linked with a database of project information” according to American Institute of Architects
What is BIM?
• Multiple models into a “composite model”

Key elements of integrated design process
• Inter-disciplinary collaboration between architects, engineers, cost consultants and facility managers
from the beginning of the design process
• Discussion of the various important performance issues and the establishment of a consensus on this
matter between client and designers
• Budget restrictions applied at the whole building level, with no strict separation of budgets for
individual building systems.
• Involvement of specialists (e.g. energy engineering, energy simulation, daylighting, comfort)
• Data sharing
• Clear articulation of performance targets and strategies, to be updated throughout the process by
the design team
• Documentation and transparency of design decisions

The benefits….
…don’t have to rebuild geometry to run analysis…the potential to change the dialog between architects and engineers

How it works:1.Draw Geometry in Autodesk Revit
2. From the Revit Toolbar:
• Set Building Location
• Define Building Parameters:• Building Type• Construction Materials• Building System Types• Room Types
3. Launch IES VE-Toolkits/VE-Pro
4. Choose Analysis Type

Adjacencies
Adjacencies
We spoke about the importanceof ‘rooms’. Within Revit, you candefine a wall to be an exteriorwall, but this will mean nothingwhen it comes to the gbXMLtranslation. The only way a wallis recognized as an exterior vsan interior wall is by theiradjacencies.
So for an element to be definedas ground floor slab, it is ahorizontal surface adjacent to aroom (otherwise it is a shadingdevice) that is not in contact withany room below. For a floor, it’sa horizontal surface that is incontact with a room above andbelow. For a roof, it’s ahorizontal surface that is not incontact with any room above.
Exterior walls are verticalsurface that is not in contact withan adjacent room on one side
Adjacencies
Keep It Simple
Keep your geometry as simple as possible!
• Is this geometry absolutely necessary for the type of analysis I am running?
• Can I eliminate anything from my model? (Purge unused, etc)
• There are often thousands of shading surfaces in a Revit file. If you are doing a daylight analysis, are the 4 cm mullions going to affect the outcome? They will affect the runtime significantly.
