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;
accessing actual energy consumption data for said at least one component of said building system;
calculating a difference between said expected energy consumption value and said actual energy consumption data;
comparing said difference with a predetermined threshold;
generating an output based on said comparing;
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.
