摘　　要：随着超低能耗建筑的不断推广使用,建筑外墙厚度和窗洞形式发生较大变化,原有的侧面采光计算方式存在较大偏差,为了更加准确地分析采光问题和评定采光系数,解决现有采光系数平均值计算方式在超低能耗建筑背景下偏差较大的问题,利用数学三角函数,通过对采光系数平均值计算原理研究,改进和完善采光系数平均值的计算公式,得到更加准确、更加贴近模拟采光实验数据的计算数值。With the further promotion of the utilization of low energy-consumption buildings,there have been great changes on the thickness of the external wall and openings of the windows of the buildings.The original side lighting calculation method has a relatively large deviation.In order to more accurately analyze the lighting problem and evaluate the lighting coefficient,it is important to solve the problem that the existing average calculation method of lighting coefficient has a large deviation under the background of ultra-low energy-consumption buildings.Using mathematical trigonometric function,through the research on the calculation principle of the average value of the lighting coefficient,the calculation formula of the average value of the lighting coefficient is improved and perfected so as to obtain the data that is more accurate and closer to the simulated lighting experiment data.
