Abstract

A system for monitoring equipment operating parameters of a remote system includes a monitor that communicates with a controller of the remote system, and at least one piece of equipment operable within the remote system, and that communicates with the controller. The equipment has at least one associated operating parameter. The monitor compares a present value of the associated operating parameter to a previous value to determine a difference therebetween. The difference is associated with a cost, measuring the cost of operating the equipment at the present operating parameter.

Claims

1. A set-point monitoring system comprising:

a monitor in communication with a controller associated with at least one piece of equipment operating at an associated set-point, and monitoring a present value of said associated set-point, comparing said present value to a previous value of said associated set-point, and recording said present value if different than said previous value.

2. The system of claim 1, wherein said monitor determines a monetary cost based on a difference between said present value and said previous value.

3. The system of claim 1, wherein said monitor continuously monitors the associated set-point.

4. The system of claim 1, wherein said monitor periodically monitors the associated set-point.

5. The system of claim 1, wherein said monitor is alerted to a change in the associated set-point.

6. The system of claim 1, wherein said previous value is a benchmark value.

7. The system of claim 1, wherein said previous value is a previously monitored value.

8. The system of claim 1, further comprising a communication network enabling communication between said monitor and the remote system.

9. The system of claim 8, wherein said communication network is the internet.

10. A method comprising:

monitoring an operating parameter of a piece of equipment of a remote system;

comparing a present value of said operating parameter to a previous value;

indicating a change if said present value is different than said previous value;

recording said present value if said present value is different than said previous value; and

communicating said operating parameter and said present value to a monitoring system.

11. The method of claim 10, further comprising accessing said monitoring system via a communication network.

12. The method of claim 10, wherein said previous value is a benchmark value.

13. The method of claim 10, wherein said previous value is a previously monitored value.

14. The method of claim 10, wherein said operating parameter is a set point.

15. The method of claim 10, further comprising providing a communication network to enable communication between said monitoring system, and the remote system.

16. The method of claim 15, wherein said communication network is the internet.

17. The method of claim 10, further comprising providing a controller associated with the remote system, said controller communicating with said monitoring system.

18. The method of claim 10, further comprising:

determining a difference between said present value and said previous value; and

associating said difference with a monetary value to indicate a change in cost as a result of said difference.

19. A method comprising:

monitoring set-points associated with equipment of a plurality of remote systems;

comparing present values of said set-points to corresponding previous values;

indicating respective changes if said present values are different than said previous values;

recording said present values if said present values are different than said previous values; and

communicating said present values and said previous values of said set-points to a monitoring system.

20. The method of claim 19, further comprising accessing said monitoring system via a communication network.

21. The method of claim 19, wherein said previous values are benchmark values.

22. The method of claim 19, wherein said previous values are previously monitored values.

23. The method of claim 19, further comprising providing a communication network to enable communication between said monitoring system and the plurality of remote systems.

24. The method of claim 23, wherein said communication network is the internet.

25. The method of claim 19, further comprising providing controllers associated with each of the plurality of remote systems, said controllers communicating with said monitoring system.

26. The method of claim 19, further comprising:

determining respective differences between said present values and said previous values; and

associating said differences with monetary values to indicate a change in costs as a result of said differences.

27. The method of claim 26, further comprising totaling said monetary values to determine one of an aggregate increased and decreased cost.

28. A monitoring system for equipment operating at an associated set-point, the monitoring system comprising:

a monitor in communication with equipment, said monitor monitoring a present value of the associated set-point, comparing said present value to a previous value of said associated set-point, determining a difference between said present value and said previous value, and associating a monetary value to said difference.

29. The system of claim 28, wherein said previous value is a benchmark value.

30. The system of claim 28, wherein said previous value is a previously monitored value.

31. The system of claim 28, wherein said monitor records said present value if different than said previous value.

32. The system of claim 28, further comprising a communication network enabling communication between said monitor and the remote system.

33. The system of claim 32, wherein said communication network is the internet.

34. The system of claim 28, further comprising a controller associated with the equipment, said controller communicating said present value and said previous value to said monitor.

35. The system of claim 28, wherein the equipment includes multiple types of equipment, each having a respective associated set point, said monitor monitoring a present value of each respective associated set point, comparing said present values to respective previous values, determining respective differences between respective present values and respective previous values, and associating a monetary value to each respective difference.

36. The system of claim 35, wherein said multiple types of equipment are selected from a group including:

HVAC, refrigeration, ACH and lighting.

37. A method comprising:

monitoring respective operating parameters of multiple types of equipment;

comparing a present value of each said respective operating parameter to a previous value for each type of equipment;

determining a difference between each respective value; and

associating a monetary value with said difference.

38. The method of claim 37, further comprising communicating said monetary value to a monitoring system.

39. The method of claim 37, further comprising communicating said difference to a monitoring system.

40. The method of claim 37, further comprising accessing said monitoring system via a communication network.

41. The method of claim 37, wherein said previous value is a benchmark value.

42. The method of claim 37, wherein said previous value is a previously monitored value.

43. The method of claim 37, further comprising recording said present value if different than said previous value.
