First Claim
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 correlating 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 compares said expected energy consumption values with said actual energy consumption data and generates an output based on said comparison.

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.
