Developing Exhaust Air Energy Recovery Credits for the Florida Energy Code
Energy recovery ventilator (ERV) or Heat Recovery Ventilator (HRV) devices recover energy from building's exhaust air to precondition outdoor air. Energy savings of ERV/HRV devices were determined for various commercial builings in Florida climate using whole building energy simulation tool. The annual HVAC energy percent savings due to ERV/HRV device were calculated from HVAC energy use of a standard reference building without and with ERV/HRV device using EnergyPlus. The annual HVAC energy savings potential (ERV Credits) will be used for code compliance calculation when a compliance softwware does not have ERV modeling capability. The ERV/HRV credits were reported by building type and climate zone.
