EnergyPro offers three possible scenarios here for modeling this type of device as follows:
Nonresidential Calculations that use ducted HVAC systems in EnergyPro that are not Zonal (FPFC, PTAC, WSHP, VRF) have Exhaust Air Heat Recovery ERV or Heat Recovery Ventilator HRV as an option on the HVAC system. See the Outside Air tab in the Central System Library for these input options.
Nonresidential Calculations can also specify at the Zone level of the Building Tree, Mechanical tab, the use of a Balanced Ventilation system with the option of energy recovery. This is a new option in EnergyPro 8, and would typically apply to an ERV or HRV in a highrise residential application.
Lowrise residential buildings have the option also. Start by going to the Top level of the Building Tree, Residential tab and specifying a non-default IAQ fan. Now at the Zone level of the Building Tree, Dwelling Units tab you can configure the IAQ fan as a balanced ventilation system with the option of specifying the heat recovery effectiveness.
