Temperature control system and methods for operating same

A method for operating a temperature control system for a structure, the method comprising:

• monitoring indoor and outdoor temperature;
• monitoring an operating state of the temperature control system;
• predicting a space temperature and an outdoor air temperature for a subsequent time period;
• estimating an operating metric for temperature control system based upon the (a) monitored interior temperature of the structure, (b) monitored outside air temperature, (c) monitored operating state of the temperature control system, (d) predicted space temperature, and (e) predicted outdoor air temperature;
• and
• controlling the temperature control system during the subsequent time period based upon the estimated operating metric.

A method for operating an HVAC system having a cooling system and ventilation system to vent outside air within a structure the method comprising:

• monitoring an interior temperature of the structure;
• monitoring an exterior temperature of ambient air outside of the structure;
• defining a first time range and a second time range;
• associating one or more operating parameters of the HVAC system with the first time range and associating one or more operating parameters of the HVAC system with the second time range;
• monitoring operational time and operational load of the cooling system for the first time range;
• and
• controlling the ventilation system during the second time range based upon the monitored operational time and operational load of the cooling system in the first time range, and the monitored interior and exterior temperatures.
