Claim One:
1. A method of constructing a predictive model for building energy consumption, comprising: receiving historic energy consumption data associated with energy consumed in a building; determining enthalpy of air outside the building; and calibrating, by a processor, an energy consumption model that predicts the building energy consumption, the energy consumption model incorporating enthalpy difference between a balance enthalpy and the enthalpy of air outside the building, the calibrating performed based on the historic energy consumption data and the enthalpy of air outside the building, wherein the energy consumption model implements energy consumption measured per time period per sensor in the building in terms of a base enthalpy load over the time period, heating enthalpy load over the time period and cooling enthalpy load over the time period, the heating enthalpy load over the time period determined as a sum over a number of time intervals during the time period, of maximum of a zero value and a difference between the balance enthalpy associated with the sensor and an enthalpy of outside air at a respective time interval, the cooling enthalpy load over the time period determined as a sum, over the number of time intervals during the time period, of maximum of a a zero value and a difference between the enthalpy of outside air at the respective time interval and the balance enthalpy associated with the sensor, wherein the calibrating determines at least a first factor associated with the base enthalpy load over the time period, a second factor associated with the heating enthalpy load over the time period and a third factor associated with the cooling enthalpy load over the time period, the method further comprising providing a user interface allowing a user to interact with the processor to execute the predictive model and to present on a display device a graph display of one or more predicted results of the building energy consumption.
