Based on the generic dynamic building energy simulation environment, EnergyPlus, the simulation model of energy recovery ventilator (ERV) is built in this paper. With different indoor temperature setpoints, the energy performance of ERV along with the availability of ERV is investigated both for Beijing and Shanghai weathers in China in terms of the ratio of heat recovery to energy supply by HVAC devices and ERV. Simulation results show that the seasonal average of the ratio is linear with indoor temperature set-points. The availability of ERV in Shanghai is better than that in Beijing during the winter. The indoor temperature set-points have the reverse effects to the availability of ERV in the midseason and to that in the hottest months in Shanghai.
