Claim One:
1. A method for predicting energy consumption of an HVAC system, the HVAC system configured for cooling air within a building, heating air within a building, or both, the method comprising: providing a model for an indoor temperature, y, of the building; providing a model for an operating state, u, of the HVAC system; providing predicted future outdoor temperatures; calculating predicted future indoor temperatures of the building and predicted future operating states of the HVAC system utilizing at least the model for y, the model for u, and the predicted future outdoor temperatures; estimating a predicted future energy consumption of the HVAC system based at least in part on the predicted future operating states of the HVAC system; and changing a control temperature of the HVAC system based at least in part upon the predicted future energy consumption of the HVAC system, wherein the model for y comprises 
 y k =a 1 y k-1 +a 2 y k-2 +b 1 v k-1 +b 2 u k-1 where y k is an indoor temperature of the building at time k, y k-1 is an indoor temperature of the building at time k−1, y k-2 is an indoor temperature of the building at time k−2, v k-1 is an outdoor temperature at time k−1, u k-1 is an operating state of the HVAC system at time k−1, and a 1 , a 2 , b 1 , and b 2 are constants.
