The aim of this numerical investigation is to analyze the performance of a building integrated photovoltaic/thermal (BIPV/T) system from exergoeconomic and enviroeconomic points of view for Kermanshah, Iran climatic condition. In the proposed system, the cooling potential of supply air and exhaust air is used for cooling the PV panels as well as heating the supply air by heat rejection of the panels. The results showed that the yearly total amount of 3038.83 kWh thermal energy, 2259.64 kWh electrical energy, and 19.97 kWh useful exergy could be saved by using the studied BIPV/T system. Furthermore, the annual reduction of 5.94 tons of CO2 emission was achieved by using the proposed BIPV/T system. Finally, it was revealed that proposed system provides 32.52% of the required heating load for ventilation air on the average basis.
