Residential HVAC assumptions

Residental HVAC

All residential models have ducted central air conditioning and gas-fired furnace heating. The MASControl database was used togenerate inputs that vary HVAC performance parameters (i.e., fan power, heating and cooling efficiency) based on vintage and climate zones, and were applied accordingly to each prototype model. The HVAC systems operate all hours of the year, cycling on/off as needed to meet heating and cooling setpoints.
