Temperature Design Conditions
Your heating and air conditioning system has been designed and sized to provide maximum comfort and energy efficiency, as outlined by the State of California Title-24 Energy Requirements. Below are the design assumptions used for calculating your home’s heating and cooling loads:
Outdoor Design Conditions: Winter: 0.2% design temperature of 31°F for Sacramento. This temperature will be met or exceeded 99.8% of the time, all year. Summer: 1.0% design temperature of 98°F for Sacramento is to be used for air conditioner sizing.
Indoor Design Conditions: Winter: 68°F indoor, as dictated by the California Energy Commission (CEC). Summer: 78° F indoor, with a 4.5° swing factor, as directed by the CEC and Federal Housing Administration (FHA).
