Claim One:
1. A method of generating a thermodynamic model of a structure associated with a heating, ventilation, and air conditioning (HVAC) system, the method comprising: receiving a request for a thermodynamic model of a structure that predicts an indoor temperature trajectory of the structure in response to application of an HVAC actuation state; acquiring time information, temperature information, and HVAC actuation state information for a period of time during which the HVAC system controls a thermal environment of the structure; determining a plurality of weighting factors corresponding to a respective plurality of predetermined basis functions, the weighted combination of basis functions characterizing an indoor temperature trajectory of the structure in response to a change in the HVAC actuation state, the basis functions including an inertial carryover component that characterizes a carryover of a rate of indoor temperature change that was occurring immediately prior to the change in actuation state; and in response to the request, returning a thermodynamic model including the determined plurality of weighting factors corresponding to the respective plurality of predetermined basis functions.
