Abstract

A method includes calculating an energy consumption model for at least one component of a building system, accessing actual weather data, applying the actual weather data to the energy consumption model, and determining an expected energy consumption value for the at least one component of the building system based on the applying.

Claims

1. A method comprising:

calculating an energy consumption model for at least one component of a building system;

accessing actual weather data;

applying said actual weather data to said energy consumption model;

determining an expected energy consumption value for said at least one component of said building system based on said applying.

2. The method of claim 1 wherein said determining occurs at least one of hourly, daily and monthly.

3. The method of claim 1 further comprising:

accessing actual energy consumption data for said at least one component of said building system;

comparing said expected energy consumption value with said actual energy consumption data.

4. The method of claim 3 wherein said comparing occurs at least one of hourly, daily and monthly.

5. The method of claim 3 further comprising generating said actual energy consumption data with an energy sensor in communication with said at least one component of said building system.

6. The method of claim 5 wherein said energy sensor measures kilowatt-hours.

7. The method of claim 1 wherein said energy consumption model functionally relates weather data and system data for said at least one component of said building system with expected energy consumption data for said at least one component of said building system.

8. The method of claim 7 wherein said system data comprises at least one of OEM design data, control methods and operating parameters for said at least one component of said building system.

9. The method of claim 3 further comprising generating an output based on said comparing.

10. The method of claim 9 wherein said generating said output based on said comparing includes generating an alarm.

11. The method of claim 1 wherein at least one of said calculating, said accessing, said applying and said determining are performed by a computer.

12. The method of claim 11 wherein said computer is at least one computer of the following group of computers:

case controller, system controller, building system controller, building system server, in-store information system, local area network computer, wide area network computer, third-party computer, processing center, management center.

13. The method of claim 11 wherein said computer is a local computer located at a location of said building system.

14. The system of claim 11 wherein said computer is a remote location located outside of a location of said building system.

15. The method of claim 1 further comprising generating said actual weather data with a weather sensor at a location of said building system.

16. The method of claim 1 further comprising generating said actual weather data with a weather sensor located at a weather station near a location of said building system.

17. A computer-readable medium having computer-executable instructions for performing the method of claim 1.

18. A computer-readable medium having computer-executable instructions for performing the method of claim 2.

19. A computer-readable medium having computer-executable instructions for performing the method of claim 3.

20. A computer-readable medium having computer-executable instructions for performing the method of claim 4.

21. A computer-readable medium having computer-executable instructions for performing the method of claim 7.

22. A computer-readable medium having computer-executable instructions for performing the method of claim 8.

23. A computer-readable medium having computer-executable instructions for performing the method of claim 9.

24. A computer-readable medium having computer-executable instructions for performing the method of claim 10.

25. In a system for managing energy consumption of a building system, a software module with instructions for:

accessing actual weather data;

applying said actual weather data to an energy consumption model for at least one component of said building system;

determining an expected energy consumption value for said at least one component of said building system based on said applying.

26. The software module of claim 25 wherein said determining occurs at least one of hourly, daily and monthly.

27. The software module of claim 25 with instructions for:

accessing actual energy consumption data for said at least one component of said building system;

comparing said expected energy consumption value with said actual energy consumption data.

28. The software module of claim 27 wherein said comparing occurs at least one of hourly, daily and monthly.

29. The software module of claim 27 wherein said actual energy consumption data for said at least one component of said building system is generated by an energy sensor in communication with said at least one component of said building system.

30. The software module of claim 29 wherein said energy sensor measures kilowatt-hours.

31. The software module of claim 25 wherein said energy consumption model functionally relates weather data and system data for said at least one component of said building system with expected energy consumption data for said at least one component of said building system.

32. The software module of claim 31 wherein said system data comprises at least one of OEM design data, control methods and operating parameters for said at least one component of said building system.

33. The software module of claim 27 with instructions for generating an output based on said comparing.

34. The software module of claim 33 wherein said generating said output based on said comparing includes generating an alarm.

35. The software module of claim 34 wherein said alarm is a local notification at a location of said building system.

36. The software module of claim 34 wherein said alarm is a remote notification at a location remote from a location of said building system.

37. The software module of claim 25 wherein said actual weather data is generated by a weather sensor located at a location of said building system.

38. The software module of claim 25 wherein said actual weather data is generated by a weather sensor located at a weather station near a location of said building system.
