Due to the selection of solar radiation spectrum by solar cells in semi transparent photovoltaic windows, the energy consumption, indoor daylight and thermal environment of photovoltaic window buildings are different with clear glass window buildings. When semitransparent photovoltaic windows are applied to building, specific design values for thermal parameters are required for reference, but there is a lack of basis. Therefore, this paper took an office building in Taiyuan as an example, established a reference building model and a design building model, and explored the influence of the Heat Transfer Coefficient (Uvalue) and Solar Heat Gain Coefficient (SHGC) on the energy consumption of semi transparent photovoltaic window buildings. The recommended range of Uvalue and SHGC value of photovoltaic window is obtained by the method of tradeoff judgment. The results show that smaller Uvalue and larger SHGC value are more beneficial to energy saving when photovoltaic windows are used in Taiyuan. When the windowwall ratio of photovoltaic window building is greater than 0.60 and the transmittance is equal to 0.46, the maximum Uvalue limit is 1.9 times the existing energysaving standard limit. By comparing the recommended range of SHGC value with different window wall ratio, the lower limit of SHGC decreases by 25%.
