摘　　要：为了评估上海某办公建筑的朝向、窗墙比及光伏玻璃透光率对该栋建筑天然采光的影响,采用Radiance数值模拟方法,分析建筑的不同朝向、窗墙比、光伏玻璃不同透光率对室内自然采光中满足SDA300/50%及ASE1000,250/10%条件的面积占比。结果表明,该栋办公建筑的不同朝向和窗墙比应在太阳光直射面选择0.4~0.5之间时,能够满足SDA300/50%≥70%且ASE1000,250≤10%,并增加遮光措施;光伏玻璃透光率对自然采光的影响较大,透光率约0.3时,在满足自然采光工况下进行光伏发电能够减少项目能耗。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.
