Dear BACneteers,

With this edition of BACnet Middle East journal, we are continuing the tradition of issuing one every year to coincide with BIG­5 show in Dubai.

Over the past 12 months, BACnet has expanded its foot­print across the region, with several large installations in GCC and the wider Middle East area. BACnet systems are now implemented in major verticals such as Education, Healthcare, Hospitality and Commercial buildings.

There is also an effort underway by BACneteers here in Dubai to arrange BACnet Interoperability workshop in first quarter on 2012. The last such event in Dubai was organized in 2008. This would provide an opportunity for BACnet vendors to integrate their systems with each other, while providing a platform to demonstrate technology to local industry stakeholders.

While BACnet is now widely accepted as a popular Open Standard Protocol to achieve integration at the Automation and Management layers, customers often enquire about how it can contribute to Sustainable Environments. The Ashrae Green­guide defines Sustainability as a method for “providing for the needs of the present without detracting from the ability to fulfill the needs of the future”.

So how can BACnet protect the interests of the future? Various control strategies have been implemented by different BACnet vendors in order to achieve this, some of which are reflected in articles appearing in this journal. Eventually these strategies need to find their way into project specifications.

That’s when the true potential of BACnet will have been realized.

I hope you will enjoy reading this edition, as much as we have enjoyed bringing it to you!

Commissioned by H.H. Sheikh Zayed bin Sultan Al Nahyan, the Grand Mosque in Abu Dhabi is a building full of superla­tives: With 50,000 m2 over­all site dimension it can ac­commodate more than 40,000 faithful, being the third largest mosque world­wide. The main prayer hall (5,815 m2) which accom­modates 9,000 worshippers has the world’s largest hand­knotted carpet (over 2 mil­lion knots) and the greatest Swarov ski crystal chande­

lier (15 m height, 10 m di­ameter). The inner court­yard, garnished with nearly 17,000 m2 of beautiful floral marble mosaic, is another example of the magnificent dimension of this unique ar­chitectonical master piece.

Size and complexityBut the true challenge of this project was not only in the pure dimensions of the building itself: The Grand Mosque is also a place with a highly fluctuating number of visitors, extreme peak­

Sheikh Zayed Mosque – Siemens Building Management for a Grand Building

The Grand Mosque in Abu Dhabi is not only one of the most beautiful buildings of the Arabian world, but also a very special one when it comes to modern building management systems (BMS). Using the power of BACnet and the flexibility of its Desigo system, Siemens could contribute to this great project and assist in making it one of the most modern buildings in the region.

times, huge and unusually shaped rooms, hallways, minarets and intersection areas, rarely found in any regular building.

Simultaneously, the Mosque is a great piece of art, which might not be disturbed by any visually striking techni­cal objects.

So the customer’s expect­ations to the building auto­mation were obvious: Hig­ est system availability, user­ and visitor friendliness, op­timal comfort and, last but not least, an energy effi­cient operation.

BACnet solution with DesigoBACnet once again turned out as a perfect technology to not only address all the main

HVAC requirements, but also to integrate 3rd party func­tional subsystems like fire alarm, power generators or monitoring the central bat­tery system: Whilst the main communi cation runs on a modern, cost­efficient TCP/IP­backbone network using native BACnet/IP, all other disciplines were seamlessly in­tegrated from LonWorks into the BACnet world, allowing for a comprehensive central building management system based upon Desigo Insight.

In total, the BMS fully controls and monitors the following equipment:

� 126 Desigo PX BACnet DDC controllers

� 118 DDC panels with portable operator terminals (PXM20)

The main prayer hall which accommodates 9,000 worshippers has the world’s largest hand-knotted carpet (over 2 million knots) and the greatest Swarovski crystal chandelier.

BACnet Middle East Journal 3 11/11 7   

� 203 Fan Coil Units (RXC)

� 14 BACnet routers (PXG80­N)

� 11 LON gateways (PXR11)

� 8000 data points

Challenging architecture“There’s size and there’s size!” – Rajesh Vaswani summarised his experience as Siemens Project Manag­er with a smile. “A lot of interesting details showed up in this project which we had to tackle with the full flexibil i ty and programma­bility of the Siemens Desi­go system”.

To illuminate the great chal­lenges of this project he added some examples. The customer wanted an intelli­gent solution, which should adapt to both the quite dif­ferent daily operating sched­ules (e.g. prayer times) as well as to different occu­pancy zones within the huge halls themselves. Thus the system had to transfer data from multiple air hand ling units (AHUs) with about four sensors per each con­troller as BACnet objects to the main controller of a par­ticular AHU. Here, a spe­cial averaging algorithm was

used to decide the optimal set points.

To reduce energy costs and realize a more sustainable building solution through the whole year, functionality was added to use a free­cooling approach in winter.

To ensure utmost flexibility, reliability and comfort even during hot summer days and at peak­times with fre­quent openings of the main entrance doors – our sys­tem had to grant automatic, energy efficient adaption to each such situation, regard­less of the outside tempera­ture.

Highest reliability and pre­cision of the HVAC system was achieved by providing over 200 fan coil units – each one linked to its own sensor. Each Air Handling Unit serving the prayer halls was equipped with at least two sensors (and thus, also at least two controllers) to guarantee full redundancy. A central battery backup system (linked into the BACnet BMS by a LON gateway) is used in case of power failure.

The large 82 domes (highest

70 m) and 4 minarets (351 feet high) were also special, explains Rajesh Vaswani. Sharing a common air volume with the ground floor, “pockets of air” could lead to water condensation. Once again thanks to the flexibility of the PX controllers and Desigo system, it could be ensured that any humidity situation which could possibly endanger the precious carpets and wall art within the mosque was avoided.

Respecting the highly aes­thetically appealing archi­tecture of the building, we had to meet equally high customer expectations for the installation of our equip­ment. Our field sensors thus were integrated into the wall’s decoration in a way mimicking its optics, getting literally invisible.

SummaryThe consultants wanted a very complex sequence of operation modes for a very special and complex build­ing. Due to the close col­laboration in a prior pro­ject (the Sheraton Hotel in Abu Dhabi), the team had a very good mutual commu­nication in the initial phase

of the project. This led to a deep understanding of ex­pectations and allowed to be fully prepared with best resources for supply, engi­neering, testing and com­missioning from day one on. “Thanks to the power and flexibility of our DESI­GO system, Siemens could meet the customer’s expec­tations in this unusual, but beautiful project.” con­cludes Rajesh Vaswani.

Enormous Flexibility and High Level Integration with BACnet

Ruwais Hospital in Al Ruwais, United Arab Emirates is a newly-built, well-equipped medical complex providing general and emergency medical services at its remote desert location approximately 250 km west of Abu Dhabi city. Constructed by the Abu Dhbai National Oil Company (ADNOC), Ruwais Hospital serves residents of the Ruwais Housing Complex – including ADNOC workers and their families- and other members of the community. Highly skilled doctors and nurses don’t rest until all patients in this 150 bed, two floor facility have been carefully attended to.

gration, industry trends are moving towards BACnet, and it is widely recognized by consultants. Further­more using BACnet meant that the Ruwais Hospital’s BMS, which would encom­pass over 900 DDC con­trollers and 15000 data points, could still be easily expanded in the future.

SIBCA chose the BACnet pioneer Alerton as sys tems manufacturer because of its top­to­bottom native BACnet solution and be­

cause of the Alerton BAC­talk system’s flexibility. “Using Alerton and BAC­net allowed us to inte­grate with the lighting con­trol system from Siemens, the fire alarm system from Simplex, to monitor sta­tus of the Inotec emergen­cy system, and to interface with Johnson Controls’ access control and CCTV systems,” said Jayaram Nagesh Mendon, Senior Sales Manager BMS & Automations Systems of SIBCA Electronics.

As a specialist in design of wooden buildings, Steffen Holzbau planned and built the facility in cooperation with Sanichaufer based in Luxembourg – where the building is situated – and the contractor GIGA­Au­tomation of Saarbrücken in Germany. GIGA­Automation is a PcVue Solutions Certi­fied Partner which provides integrated building man­agement systems (IBMS) in Germany and Luxembourg. The BACnet network was developed to rigorous spec­ifications: PcVue for the op­erator workstation and con­trol system, DDCs from SAIA Burgess with native BACnet communication and a Menerga Control System for the swimming pool and therapy controls.

The building conforms to the Passivhaus standard for energy efficiency with min­

imum ecological foot print. The clinical and adminis­trative areas have each been optimized for ultra­low en­ergy usage across several kinds of heating and cool­ing. Two central ventilation systems provide sterilized air for both areas. The cooling and heating plant uses spe­cial convector systems built into the floors and arranged in front of the window sur­faces.

The ventilation is equipped with efficient heat recov­ery systems and adiabatic cooling. There are approxi­mately 50 m² of solar pan­els on the roof for hot wa­ter production and heating support. As backup for the solar water heating (140 kW) both the ventilation and the pool heating are as­sisted by woodchip boilers (100 kW) and an oil­burn­ing system.

Trend-setting Ultra-low-energy Building

This trend-setting building comprises a clinic for physiotherapy and medical muscle-building plus the offices of the builder, Steffen Holzbau. All of the efficiency systems are monitored from a PcVue BMS system with remote WebVue access linked to BACnet controllers and communication.

The therapy pool of high­grade steel has a water treatment plant installed to ensure water quality. The

pool is equipped with a countercurrent feature and underwater massage nozzles. Space heating and dehumidi­

Alerton’s fully­programmable communicating sensor­con­troller with configurable dis play, VisualLogic Display (VLD), allowed each piece of equipment to be individually controlled and provided a modern, user­friendly, touch­screen inter face. The VLD along with the VAViH­SD, a versatile BACnet­compliant controller with integrated actuator, controls Variable Air Volume (VAV) units in the Intensive Care Unit (ICU) and maternal delivery suite to provide the required amount of treated air for those spaces.

In addition to VAV boxes, the Alerton Envision for BACtalk system controls Air Handling Units (AHUs), Fan Coil Units (FCUs), Chillers, and even plumbing (e.g. water pumps). Honeywell peripherals including valves and actuators complete the solution.

With BMS commissioning finishing up shortly and the total project scheduled for completion by the year end, ADNOC can sleep soundly knowing that the Ruwais Hospital’s BACnet­based Alerton BMS will be

working around the clock to ensure the comfort and safety of patients in its facilities now and in the future.

ESAC, a BACnet System Integrator in Italy, together with the Energy Efficiency Department of the Polytech­nic University of Turin, con­ducted a research project to build an automatic energy consumption control and optimization system. This system is to be installed in office buildings of the Pied­mont regional administra­tion in north­west Italy. The project, named BComfort, confirmed what many well known building energy con­sumption analysis companies foretold.

BACnet and the integrated metering, analysis and control systemFirst we set up the ex­perimental method and following the same method we found BACnet to be the best integration platform. The ISO 16484­5 (BACnet) standard, more than offering real interoperability among

devices from different pro­ducers, is based on an extremely scalable system design that allows our small and simple solutions to be interconnected in a much more complex system scattered over the region.

ISO 16484­3 standard describes building automa­tion logic functions and BACnet (ISO 16484­5) rep­resents those functionalities under the information tech­nology point of view. ISO 15232 “Energy performance of Buildings – Impact of Building Automation, Con­trols and Building Manage­ment” refers to ISO 16484­3 in evaluating energy efficien­cy of building automation functionalities. In Europe ev­ery country is working on the EPBD (Energy Performance of Buildings Directive) and ISO 15232 is an extreme­ly important focus on build­ing energy efficiency evalu­

The best way to save money is to keep systems switched off, we would achieve an unbelievable energy surplus, but who of us can work in an office with stale air, no conditioning and no lighting? At our work place, the goal is always to achieve the best “compromise” between comfort and energy consumption – lowering energy consumption while maximising comfort.

It is evident that BACnet can be considered not only as a communication protocol but also as a point of convergence for different systems within the building. So why should we reinvent the wheel?

Certification became pos­sible by leveraging an inte­grated design approach and mobilizing a “Green Build­ing” team in the early stag­es of the building’s design. A very important player on that green team was Temp­master Israel, a local ener­gy management firm and a KMC Controls authorized re presentative. Understand­ing that a high­efficiency HVAC and building auto­mation system would play the largest role towards, not

only energy conservation, but also indoor air quality and occupant comfort, the team came to rely heavily on Tempmaster. “Their exper­tise, knowledge, and profes­sional presence were excep­tional. Our systems at IDC 9 are highly complex and Tempmaster succeeded in keeping things simple. We are fully operational with a very reliable system,” com­mented Tzach Namer, the Mechanical/Electrical Proj­ect Manager at Intel.

Gold for Most Advanced Engineering

Computer hardware giant, Intel Corporation, received LEED Gold certification for its latest design/data center – IDC 9 – that opened in Haifa, Israel on June 15, 2010. The all-new facility boasts the most advanced engineering infrastructure and is Intel’s first LEED-certified green facility, as well as the first building in Israel to receive LEED Gold certification. The 259,000 square foot facility is noted for housing a 6500 square foot high performance data center.

Utilizing KMC’s BACnet controllers, Tempmaster in­tegrated with the Schneider Electric programmable logic controllers and GE SCADA systems to give Intel engineers precise control over their air handling systems. KMC’s STE­6011 room temperature sensors installed throughout the employee offices and cubicles are connected to the inputs of approximately 400 KMC BAC­7003 BACnet Advanced Application Con­trollers mounted on the VAV

terminal units serving those spaces. In turn, 12 KMC BAC­7301s create a “hard­wire” data interface between the MS/TP net and the PLC in control of the local air handling unit’s fan speed drive and chilled water valve to minimize fan power and unnecessary cooling energy.

The BAC­7301s are connect­ed to five KMC BACnet routers working through a pair of BACnet OPC servers which form the

Other BACnet manu facturers represented in this project include Trane (chillers and burner control units) and ABB (variable frequency drives).

IDC 9 also measures carbon dioxide levels for improved air quality, captures and recycles condensate water from the AC system and uses it for irrigation and heating the building with dissipated heat from ACs and data center computers.

Although there are a number of other noteworthy elements of sustainability that contributed to the facility’s LEED Gold certi­fication (such as rooftop gardens, processor­based data center, chimney racks, and day lighting), the advanced HVAC and building automation systems will have the greatest impact on ROI potential.

Elegant Property Setting High Standards in the Heart of Zurich

Only a few minutes’ walk away from the lake, the Stockerhof residential and commercial complex in Zurich enjoys an exclusive location surrounded by historic buildings. The main shopping area, the banking district (the business hub of Switzerland’s financial centre), numerous service firms and the Kongresshaus convention centre are all in the immediate vicinity.

The building is convinc ing esthetically and function­al. From the bright natu­ral stone and architectural bronze on the exterior fa­cade of the design lift up to the railings, it is char­acterized by especially se­lected materials and a well planned lighting.

parking spaces, storage areas and rooms for the building’s tech nical equipment the under ground storeys housed a large shopping centre together with a fitness and wellness complex. The upper storeys provide office and service areas occupied by tenants from the Swiss and international banking sec­tors. Three of the storeys also include apartments of various sizes (some with their own roof terraces) and luxurious maisonette flats.

The project consisted of 900 hardware data points and 1300 soft data points for BACnet and Modbus inte­

gration. Daikin had been selected as HVAC contrac­tor and installed a VRV­sys­tem with 256 indoor units. The VRV­system has been integrated on controller lev­el floor wise via the BAC­net IP protocol. 700 BACnet objects for monitoring and operation functions of the VRV­system have been in­tegrated seamlessly with the help of an EDE file.

Energy efficiencyThe innovative and inter­operable ATMOS building management system fulfil the aspects for sustainable energy efficiency and helps in the LEED certification process for Green Building. Optimising the economy, en­ergy efficiency and comfort of the building....throughout it’s life cycle.

In the second phase, the builder – the state office real estate and construction man­agement of Rhineland­Palati­nate –required a comprehen­sive building management system. All facilities of the complex were to be integrat­ed into this building manage­ment system via BACnet and monitored centrally. After comparing different systems, the builder chose Neutrino­GLT for the building man­agement system.

The Neutrino­GLT building management system is ideal for monitoring, control and optimization of trade­span­ning and real estate systems.

It offers guidance, data ac­quisition, alarm and con­trol functions. As interface between man and the auto­mation system, it is charac­terized with its ease of use, quick information and oper­ations system transparency.

Even while the installations were in progress, the build­er decided to integrate all sys­tems of the first phase into the system as well. The inte­gration of existing field devic­es worked without any prob­lems.With the Neutrino­GLT building management sys­tem, users can now operate and monitor all facilities on the Rhine Mosel campus cen­

Trade-spanning Integration with BACnet

The University of Applied Sciences in Koblenz, Germany has about 500 employees and 4,300 students. The Rhine-Mosel Koblenz campus is one of three of the university’s campuses. The first construction phase of this large, sprawling university building was after the founding of the university in the years 1996 to 1998; the second construction phase was from 2007 to 2009.

trally. This includes heating, ventilation and air condition­ing, elevators, gas and fire de­tection systems, the external doors, exterior and hallway lighting, as well as individual room controllers in the semi­nar rooms, lecture halls and laboratories.

High energy savings Through the building auto­mation and building manage­ment system the facility man­agement of the university has reduced its energy consump­tion by 10 percent. To further optimize the energy manage­ment, heating meters are also currently being installed.

Soon with the Höhr­Grenz­hausen campus, a further lo­cation of the university will be integrated into the system.

The university’s house tech­nicians were trained at

Kieback&Peter in Berlin to operate the Neutrino­GLT building management sys­tems. Kieback&Peter was entrusted with the mainte­nance of the systems.

The Rhine-Mosel Koblenz campus is one of three of the university’s campuses.

Integrating Building Automation into IT Environments

Building automation com po nents have grown to become fully functional IT equipment, sup­porting many functions known from other computer systems like FTP­access, telnet, web­servers, etc. plus communication over protocols like BACnet/IP. This requires that integrators need to learn to talk to IT administra­tors to make them understand which services building automa­tion needs in IT infrastructures.

TCP or UDP?The usual term used to describe internet based communication is “TCP/IP”. In fact, TCP (Trans­mission Control Protocol) is only one of many protocols on top of the internet protocol (IP). BAC­net like other communication protocols for building automa­tion don’t use TCP, but instead it uses UDP (User Datagram Pro­tocol). UDP is designed to work connectionless, which requires a bit more overhead in the applica­tion layer, but putting everything together, UDP is approximately 8 times faster in communication than TCP.

PortsBoth TCP and UDP use so­called ports to transport incoming and outgoing messages. A good example of a well­known port is TCP port 80 for HTTP­communication. For BACnet the UDP port 47808 (decimal) is reserved. An easy way to remember this port is to use the hexadecimal equivalent: BAC0 (hex). IT routers must be configured to transport UDP and open the port 47808 to allow BACnet traffic.

Broadcast and sub-networksIn modern IT environment larger networks are connected through routers. The intent is mainly to reduce broadcast traffic to a larg­er number of devices (a broadcast is a message sent to all devices in a network and has a significant im­pact on the performance of devic­es), so IT routers normally block broadcast messages. BACnet uses broadcast messages, e.g. to detect other devices by using dynam­ic device binding (Who­Is, I­Am) or dynamic object binding (Who­Has, I­Have).

BBMD and FDBBMDs (BACnet Broadcast Management Devices) can be used to tunnel the broad­cast messages. By installing one BBMD per sub­network, the broadcast messages are sent to the BBMDs of other sub­net­works using unicast messages (which are not blocked), so the broadcasts find its way into the other network segments. A FD (Foreign Device) is a single de­vice in a foreign network con­necting to a BBMD – the differ­ence is that the FD does not send the broadcast to the network while the BBMD does.

Usually an installation of one BBMD per sub­network is used in practice.

One-Hop and Two-HopA BBMD supports one of two options. If the IT routers support “Directed­Broadcast”, the IT router can take over the task to distribute the broadcast to the sub­network (One­Hop

distribution), even this is seen rarely in projects.

More commonly the Two­Hop mode is used where all BBMDs are configured to know each other and the BBMDs are responsible to distribute the broadcast messages to their local sub­networks.

DHCP and NATDHCP (Dynamic Host Configuration Protocol) is used to assign IP­addresses to devices dynamically. DHCP does not work well with BACnet components. Most DDC devices (Direct Digital Control) don’t support a DHCP client mode plus the relationship between the BMS (Building Management System) and the DDC is configured statically in most projects. So DHCP might not work well.

NAT (Network Address Transla­tion) describes how to connect a private network to a public net­work using IP address translation.

Like DHCP, NAT does not work well with most protocols and so with BACnet because the relation­ship between two communication partners requires “real” address­es. Though Addendum­O speci­fies a NAT­BBMD this would re­quire two fixed IP addresses and may not be practical at all.

VLAN and VPNVLAN (Virtual LAN, Layer2 switching plus VLAN­routing), mainly used for connections in­side an intranet or VPN (Virtu­al Private Network), mainly used for connections over the internet work excellently with BACnet. VPNs in most cases allow addi­tional security by using data en­cryption. This makes those types of networks not only practical but also secure.

ConclusionBACnet generally fits well into IT environment and may be used as a communication protocol for build­ing automation components on ex­isting LAN infrastructures.

Calender of BACnet Events

Certification of BACnet devices bases on automatical testing harmonized world wide.

Starting September 2011, the necessary conditions will have been created. Then the first awards can be presented ac­cording to the new model. In a round robin test, the laborato­ries first had to ensure that the test results were recognized worldwide. After a tour of the labs on site and interviews with the laboratory staff this recognition as a BACnet Test­ing Laboratory by the BIG­EU and BI was given.

The new method is based on the test plans of the BACnet Testing Laboratories (BTL), but also meets the Europe­an requirements for product certification procedures and guidelines. In addition, the integration with the Euro­pean Construction Products Directive and national regu­lations such as the German Energy Saving Ordinance EnEV is ensured.

BACnet standard upgradedThe internationally harmo­nized certification is a com­

mon credit of both the BIG­EU and BACnet Interna­tional. The President of the BIG­EU, Volker Röhl, sees the benefits of the consumer: “The European BACnet Cer­tification meets all guidelines with regard to certification procedures, building prod­ucts and energy efficiency.”

Andy McMillan, President of BACnet International, sees the BACnet standard as upgraded. “It is a natur­al and useful addition to the worldwide use of the BTL mark and the BTL Product Listing.” With the global certification system it will be easier for the worldwide pro­viders to meet different re­gional requirements.

Through the new process, products which were tested by SoftDEL in India on be­half of BTL can be award­ed the WSPCert Certificate. And vice­versa, displaying the BTL logo is possible if the test was conducted in the European WSPLab and

the manufacturer is a mem­ber of BACnet International. For acquiring the BTL logo and certificate the uniform procedure applies: The tests must be performed by an ISO accredited testing labo­ratory, which has also been recognized by BIG EU and BACnet International.

So far, the BIG­EU and BAC­net International have rec­ognized two laboratories as BACnet Testing Laborato­ries, SoftDel Ltd. in India – the testing laboratory of BACnet International – and the European WSPLab in Stuttgart. But the need for

testing capacity is growing as more and more users are relying on the BACnet stand­ard. So it’s good timing that two other European test lab­oratories have applied at the BIG­EU.
