Abstract:
Apparatus, systems, methods, and related computer program products for generating and implementing thermodynamic models of a structure. Thermostats disclosed herein are operable to control an HVAC system. In controlling the HVAC system, a need to determine an expected indoor temperature profile for a particular schedule of setpoint temperatures may arise. To make such a determination, a thermodynamic model of the structure may be used. The thermodynamic model may be generated by fitting weighting factors of a set of basis functions to a variety of historical data including time information, temperature information, and HVAC actuation state information. The set of basis functions characterize an indoor temperature trajectory of the structure in response to a change in HVAC actuation state, and include 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.

Claim (Index 8):
An intelligent network-connected thermostat for controlling an operation of an HVAC system in a smart home environment, the thermostat comprising:\n HVAC control circuitry operable to actuate one or more elements of the HVAC system; one or more sensors for measuring characteristics of the smart home environment; and a processor coupled to the HVAC control circuitry and the one or more sensors and operable to cause the thermostat to perform operations including:\n 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; \n 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; \n 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 \n 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.
