  1. “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 today’s 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 haven’t 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. What’s 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. What’s 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 user @ 11.6 watts per SF!

  19. Atlanta is also the biggest Dollar electric user

  20. Examples of virtual points and points from disparate systems

  21. A close-up of weekend penalty calculations

  22. What’s 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. What’s 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
