Selecting an Advanced Energy Management System May 2007 Chris Greenwell – Director Energy Markets Scott Muench - Manager Technical Sales © 2007 Tridium, Inc,

2 Agenda What customers are experiencing and seeking from advanced energy management tools What customers are needing in successful building automation systems What elements of an Advanced Energy Management System should you consider when selecting a system

3 What are todays energy managers experiencing? Rising energy cost Mixed results on Deregulation Confusion on complex tools and solutions

4 Energy Background 101 Energy costs have been trending upward due to rising natural gas prices Natural Gas prices have a direct effect on electricity

5 What about deregulation? While deregulation significantly lowered customers bills early this decade more recent experiences havent been as good Most states have put deregulation on hold; many are shifting focus to Advanced Energy Management and Demand Response More customers are seeking to manage energy today than ever…

6 Elements of an Energy Management Enterprise Real Time Point Database Historical Trend Database Alarm Management Device Management

7 Whats important with Real Time Point Database Are all systems integrated? With other systems? With other devices? With other information? Can different protocols communicate? Are systems web enabled? Can you customize your interfaces? Can you implement your strategies? Can you automate decisions? Do you have flexible scheduling tools?

8 Can occupancy be integrated to energy management at a hotel?

9 Real time occupancy by room information can save money

10 A vacant room has a lower set point in the winter

11 Global control for occupied and unoccupied rooms is an excellent way to obtain savings

12 Real time metering via a variety of protocols may also be a requirement

13 To correspond to real time data from utilities/ISOs

14 Whats important with Historical Trend Database? Can you measure and verify results? Can you benchmark results? Can you convert engineering units of the data? Can you convert energy to cost? Can you create virtual points? Can your historical database scale? Can you import and export to other database systems? Is your solution more robust than excel? Can you share and communicate results?

15 By starting the AC later, how much is saved?

16 Starting the AC a few hours later saves $1680 in February; $24,480 over the year!

17 First identify the bigger users

18 Atlanta is the highest 11.6 watts per SF!

19 Atlanta is also the biggest Dollar electric user

22 Whats important in Alarm Management? Can your system notify you the way that you need to be notified? Can your system acquire data from a variety of sources/devices, conduct analysis and then alarm? Once you have the alarm can you easily do something about it?

23 Alarming needs to be flexible and accommodate a strategic plan?

24 An alarm system needs to communicate information in a number of ways

25 Alarming needs to allow for measuring and calculating data

26 Customization is important with alarming

27 Whats important in Device Management? Can you easily add a new device to your system? Can your system learn new protocols? Can your devices integrated with other devices that speak different protocols?

28 At times it is important to communicate with many disparate devices

29 Unique devices – Grease traps

30 Unique Devices – Ovens

31 Unique Devices – Gas Pumps

32 Unique Devices – Solar Systems

33 What is important in energy management Addresses the holistic approach – the need to manage a facility as a whole to optimize performance This means lots of diverse devices The energy manger needs connectivity to devices and equipment systems –Meters –Building Automation Systems –Factory packaged equipment systems (chillers, boilers, AHUs, etc.) Needed connectivity to the Enterprise –Extensive xml/web services interfaces for: –Real time pricing feeds from utilities –Energy management applications

34 The solution must combine networking connectivity, hardware & software to enable a powerful solution Many solutions often only have products in one or two of the circles This limits their capability Total solution addresses: Connectivity (devices and enterprise) Control Data logging Analysis/reporting
