Abstract

A system and method for managing energy consumption of a building system includes a source of actual energy consumption data, a source of actual weather data, and a database correlating discrete weather data values with expected energy consumption values for at least one component of the building system. A computer accesses the actual weather data, actual energy consumption data and database, wherein the computer compares the expected energy consumption values with actual energy consumption data and generates an output based on the comparison. The expected energy consumption values are generated for the discrete weather data values using an energy consumption model that functionally relates discrete weather data values and design information for the building system component.

Claims

1. A system for managing energy consumption of a building system at a first location, said system comprising:

a source of actual energy consumption data;

a source of actual weather data;

a database associating discrete weather data values with expected energy consumption values for at least one component of the building system; and

at least one computer accessing said actual weather data, said actual energy consumption data and said database, wherein said at least one computer correlates actual weather data with said discrete weather data to select at least one of said expected energy consumption values, and compares said at least one of said expected energy consumption values with said actual energy consumption data.

2. The system of claim 1 wherein said computer generates an output based on said comparison.

5. The system of claim 1 wherein said expected energy consumption values are generated for said discrete weather data values using an energy consumption model that functionally relates said discrete weather data values and design information for said at least one component of the building system.

6. The system of claim 2 wherein said output based on said comparison generates an alarm.

7. The system of claim 6 wherein said alarm is a local notification at the first location.

8. The system of claim 6 wherein said alarm is a remote notification at a second location remote from the first location.

9. The system of claim 1 wherein said at least one 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 (ISIS), local area network (LAN) computer, wide area network (WAN) computer, third-party computer, processing center, management center.

10. The system of claim 1 wherein said computer is a local computer located at the first location.

11. The system of claim 1 wherein said computer is a remote computer located at a second location remote from the first location.

12. The system of claim 1 wherein said source of actual weather data is a sensor located at the first location.

13. The system of claim 1 wherein said source of actual weather data is a sensor located at a weather station near the first location.

14. The system of claim 1 wherein said source of actual energy consumption data is an energy meter in communication with said at least one component of the building system.

3. A method for managing energy consumption of a building system at a first location, said method comprising:

receiving actual energy consumption data;

receiving actual weather data;

associating discrete weather data values with expected energy consumption values for at least one component of the building system;

correlating said actual weather data with said discrete weather data values;

selecting at least one of said expected energy consumption values based on said correlating;

comparing said at least one of said expected energy consumption values with said received actual energy consumption data.

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

15. The method of claim 3 wherein said associating discrete weather data values with expected energy consumption values for at least one component of the building system includes generating a database using an energy consumption model that functionally relates said discrete weather data values and design information for said at least one component of the building system.

16. The system of claim 4 wherein said step of generating an output based on said comparing includes generating an alarm.

17. The method of claim 16 wherein said generating an alarm is a local notification at the first location.

18. The method of claim 16 wherein said generating an alarm is a remote notification at a second location remote from the first location.

19. The method of claim 3 wherein said selecting and comparing are performed by a computer.

20. The method of claim 19 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 (ISIS), local area network (LAN) computer, wide area network (WAN) computer, third-party computer, processing center, management center.

21. The method of claim 4 wherein said computer further performs associating and generating.

22. The method of claim 3 wherein said receiving actual weather data includes monitoring a sensor located at the first location.

23. The method of claim 3 wherein said receiving actual weather data includes monitoring a sensor located at a weather station near the first location.

24. The method of claim 3 wherein said receiving said actual energy consumption data includes monitoring an energy meter in communication with said at least one component of the building system.
