Abstract：Radiance numerical simulation method was used to evaluate the influence of orientation,window to wall ratio and photovoltaic glass transmittance on natural lighting of an office building in Shanghai.Analysis of the different orientation of the building,the ratio of window to wall,the different light transmittance of photovoltaic glass to the indoor natural lighting of SDA300/50%and ASE1000,250/10%of the area.The results show that the different orientations and window-wall ratios of the office building can meet the requirements of SDA300/50%≥70%and ASE1000,250≤10%when the direct sunlight surface is between 0.4 and 0.5,and the shading measures are added.The transmittance of photovoltaic glass has a great impact on natural lighting,and when the transmittance is about 0.3,photovoltaic power generation under natural lighting conditions can reduce project energy consumption.
