9 Overview of the European BAS Products Market A Building Automation System (BAS) is designed and implemented to monitor and control the various building services, from heating to security to lighting. It optimizes the operations of the various equipment by monitoring environmental conditions within the premises to minimize energy consumption, but simultaneously maintain a desired level of comfort. A network of controllers tied to one or ore operator workstations. Substations communicate with control components via protocols. All functions are controlled by a single or low number of central control units. The European market for BAS products is mature with moderate growth rates. Major drivers include the increase in energy costs, the growing demand for better working environment and the emphasis on climate change. The market is highly dependent on energy efficiency (EE) related legislation as well as the health of the construction market. Source:

10 Overview of the European BAS Products Market Hit by weak construction in 2009, but underlying drivers are strong due to pivotal role in controlling energy consumption. Also a key element of integration into smart grids. Integration and IP networking remain major trends in commercial sector. The largest market is Germany, followed by the Scandinavian region. In terms of end-users commercial applications account for the largest revenue share. The BAS market is a highly competitive and concentrated market with high level of consolidation.

13 European Protocol Trends in Building Automation Séminaire sur les bâtiments performants 17 Novembre 2009 Renault Square Com

14 The Need for Standard Protocols Past Main concern to control the building Proprietary communication protocols End-user locked in No compatibility within systems Building subsystems operate separately Present and Future Energy efficiency above all Standard communication protocols Mix and match of the best Integration of building subsystems Truly open systems Traditionally BASs would operate separately. As the systems from different manufacturers were not compatible, facility owners had a difficult task if wanted to improve the performance of their premises. Systems based on open communication standards could add value to the building. End-users can choose the best available options and get the most out of their control systems to achieve a more energy efficient, and therefore greener building. There are more than one protocol to choose from, each with different functionalities. By the mix and match of the best products and systems, best suiting one s needs, the project can build on the strengths of the different products using different vendors if necessary or preferred. However, the concept does not necessarily translates into deployment in reality. The majority of end-users would still only use products from a single supplier, even though the products themselves are enabled to be connected to other manufacturers products.

15 The Need for Standard Protocols Increasing demand for managing the entire building as an integrated system to make most of the benefits on offer. Communication protocols: a set of rules, message structures and the treatment of these codes and structures, which provide rules for data and information exchange over a computer network. Above all, they allow systems from multiple vendors to exchange information and synchronize equipment to achieve optimum building performance. Open protocols allow various products regardless their manufacturer to actively and interoperably communicate information on a common network. The levels of services offered by open protocols can differ from basic data sharing to more advances services, such as scheduling or alarming. Proprietary Protocols In the past, protocols were specific to the equipment manufacturer. They were initially developed for intercommunication with different components of the same manufacturer s system. Systems based on proprietary protocols only allow forward and backward compatibility with the system of the same manufacturer. Remains a choice for smaller installations Non- Proprietary/ Open Protocols Any products embedded with open protocol technology can communicate directly with any other product enabled with the same communications protocol regardless the manufacturer. The most commonly used open protocols are BACnet and LonWorks. Others include TCP/IP, KNX, ModBus and Ethernet. Disadvantage: a standard system is sometimes less customised

16 BACnet and LonWorks BACnet, introduced in 1995 by ASHREA aimed to standardise communication between building automation devices and systems from different vendors. Although it was originally developed for purely HVAC applications, today BACnet applications include other building services from lighting to fire safety to security. LonWorks, developed by Echelon as an open platform for networked devices, is based on the LonTalk protocol. Each LonWorks compatible device must contain the proprietary Neuron Chip, although it can be sourced from more than one supplier. BACnet Specifically developed for building automation by a wide group of industry professionals Software based protocol Network medium independent Used for system-to-system integration More suitable for management and automation levels where a lot of processing is needed Easier to engineer and commission Cannot be changed without public consultation LonWorks Designed by using a bottom-up approach Not limited to a specific application area, provides a wider fit in terms of building applications Best solution for device level integration More common at field level More can be achieved with it, but more complex to set up Need for more wiring Creates a flat network architecture The choice is down to which system can deliver the best value in a particular installation Each has its own merits and limitations Both has operational and economic benefits and therefore can complement each other In most cases a system would be a combination of the protocols

17 BACnet and LonWorks: What is Used in Reality? BACnet and LonWorks are tend to overlap with and converge to each other. Both are standardised customers have a choice when selecting a system. The choice is subjective and depends on various factors from the level of integration required in a particular room/area to future expansion plans. Successful implementation depends on system design, requires a knowledgeable vendor to make the right technology choices to achieve ease of operation and maintenance as well as to accommodate future expansion needs. Even though the technology exist, customers are not fully educated and still more likely to ask for a specific brand, then a system which is based on open protocols. The majority of new installations would still use products of a sole manufacturer, even though the system is open. Therefore the question today is not about the split between open and proprietary or between the standard protocols, but the level of integration.

18 BACnet and LonWorks: What is Used in Reality? Geographical differences: France and the Benelux are typical LON markets UK: BACnet is very popular Germany: BACnet, due to strong push by public organisations, the country also has an influence on the rest of Europe South of Europe: mixed picture It means that in Germany, commercial end-users tend to follow what is used by public buildings and that is BACnet New installations: BACnet, LON or KNX The majority of systems have the potential to be open, but only one in ten is believed to be truly open, i.e. using third party devices Refurbishments: Depends whether it is possible to switch to open systems or it is too expensive Reality: Many systems are open, but all parts come from the same manufacturer!

19 Standard Protocols and Energy Efficiency Séminaire sur les bâtiments performants 17 Novembre 2009 Renault Square Com

20 Energy Efficiency and Communication Protocols If all systems in a building can work together from heating to fire & security to lighting the result is the highest achievable comfort level. In terms of technology, the possibility is there to achieve that. For instance, the light and airconditioning can be switched off if the room becomes unoccupied. Building controls can play a huge role in making commercial buildings more energy efficient However, effective control depends on real time knowledge of the internal environment. The true value of BAS from the end-users point of view: Simplified operation Better coordination of the systems Remote access to data at any time ENERGY EFFICIENT BUILDING The solution is interoperability, when all equipment associated with different building systems work together, regardless of the manufacturer, even though multiple protocols exist within a building. The best way is an open system, where the protocol language is shared between the various vendors

21 The road ahead: Smart Technologies Séminaire sur les bâtiments performants 17 Novembre 2009 Renault Square Com

22 The Future: IT and Building Automation The importance of access to information Buildings account for around 40% of all the energy we consume. Within a commercial building lighting and HVAC consume around three quarters of the energy. Connecting building functions together represents a huge potential for energy savings. Energy savings is one of the most important objectives together with comfort and continuous operation. In order to achieve that, one needs to have access to real-time data to make truly informed decisions. The more information ones has, the easier it becomes to take actions. There are high benefits if one can access, monitor and control data and equipment by using open protocols. An intelligent or smart building means the complete integration of building automation and IT. By utilising IT and internet, manufacturers can get real-time access and control over their facilities systems through web browsers.

23 The Future: IT and Building Automation Convergence of systems over IT Main challenge to improve operation & maintenance and reduce costs at the same time Huge amount of data as a result of various building services being linked together This data needs to be managed and used Growing importance of TCP/IP network A group of protocols which documents data transmission and network user locations TCP is a connection-oriented protocol which facilitates reliable communications between the source and the destination. Media independent, which allows for the best match between the required communication speed and the cost for a given application. It facilitates interoperability among different building automation components from different vendors Remote access Facility managers have real time access and control over the building s systems Also by sharing infrastructure and data, BAS becomes less expensive to install and operate

25 Global Smart Technology Markets for Energy Efficiency: Headline Trends Smart Energy Efficiency Technology Market: Regional Life Cycle Analysis (World), 2009 North America Western Europe Middle East Asia Central & Eastern Europe Latin America Africa Development Growth Maturity Smart Energy Efficiency Technology Market: Key Interlocking Issues (World), 2009 Connectivity & Integration Environment Energy Supply and Costs Building Intelligence Global Energy Demand Construction Activity Outlook for Smart Technologies With electricity demand growing faster than supply, there is a clear opportunity for intelligence to be integrated into the energy management chain to improve efficiency. Energy efficiency drivers are combining with the need to modernise electricity supply networks. Smart technology brings an opportunity to marry energy management with digital communication technology. Smart technology is changing the way users interact with buildings and the way they interact with each other. Opportunities are emerging along the entire network from point of generation to point of consumption. US market currently leading the way globally with strong support from US Department of Energy, especially for smart grids. Significant global growth opportunities materialising for smart technology in energy efficiency in the short and medium term future.

26 Global Smart Technology Markets for Energy Efficiency: Emerging Market Themes Smart Energy Efficiency Technology Market: Key Drivers & Restraints (World), 2009 Drivers Restraints Electric Vehicles Growth in Renewables High Cost of Replacing Installed Base Integration of Microgeneration Short Term Budget Cuts during Recession Demand for Energy Efficiency Depressed Construction Industry Smart Energy Efficiency Technology Market: Convergence of Competition (World), 2009 IT Players Energy/ Infrastructure Players Automation/ Building Control Players Government Support Lack of Standard Communication Infrastructure Drivers Restraints Emerging Smart Technology Themes The main Smart driver is the need for energy efficiency throughout energy networks. The convergence of technology (IT, automation, energy infrastructure etc.) is leading to the convergence of competition with new players emerging in the energy efficiency space (e.g. IBM, Cisco, etc.) The broad themes of Smart Grids and Smart Buildings are creating growth in both existing and new markets (meters, software, T&D technology, automation, demand response management, sensors, analysis and reporting etc.) The market has room for both niche suppliers and multisector players, but the leading players are already positioning themselves as complete solution providers covering the whole energy chain (GE: from the power plant to the consumer; Schneider Electric: From Plant to PlugTM; ABB: Integration from Supply to Demand).

27 Conclusions Technology-wise it is all set for open systems, however, the role of consultants need to change from traditional activities and disciplines orientation to aiming to go across and cover all functions, incorporating energy efficiency goals. No single protocol will ever dominate the market the industry is not about choosing one protocol over the other, but it is about to try to integrate a multitude of protocols. The future is some sort of open protocol combining various standards, including proprietary ones which are also here to stay. Every standard allows extension which can be used for differentiation companies that offer a broad portfolio from field devices to plant controllers will be the real winners. Wireless: No significant demand yet There is future for it, the question is when it going to become a standard In new installations the cost is higher compared to traditional cabling Wireless is not to replace, but to complement wired systems The value of wireless system is higher in existing buildings due to simplified refurbishment Main protocol is ZigBee At the moment there are still security and reliability issues at automation and field levels The vision of the future is the convergence of all systems over the IT network However, the question remains open: Is there really a drive towards fully integrated projects?
