Claim One:
1. A method for operating an HVAC system, the HVAC system configured for cooling air within a building, heating air within the building, or both, the method comprising: providing a model for an indoor temperature, y, of the building, the model for y comprising 
 y k =a 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; providing predicted future outdoor temperatures; calculating future operating states of the HVAC system with a controller of the HVAC system utilizing at least the model for y, the model for J, and the predicted future outdoor temperatures; and activating the HVAC system during the future operating states of the HVAC system from said step of calculating.
