采用数值模拟的方法对办公建筑的自然采光和照明能耗进行模拟，分析了窗户的主要结构性能影响因素如窗墙比、窗台高度和窗户外形尺寸对采光系数标准值、采光系数满足采光设计标准面积比Ra和自然采光照明节能率的影响。结果表明，在任意窗墙比和窗户外形尺寸下，采光系数标准值均在窗台高度为0.8m处达到峰值；综合考虑室内采光系数标准值、满足采光标准面积比和自然采光照明节能率，窗墙比宜控制在30%左右，窗户宽高比在1～2之间；当窗墙比大于15%时，相同窗墙比、窗台高及窗户外形尺寸条件下的室内照明节能率在窗户朝向上的排序为南向>东向>西向>北向。研究结果可为建筑师进行采光节能设计时提供参考借鉴。

The natural lighting and lighting energy-consumption of model-building are simulated through numerical software, and the standard value of daylight factor, the area ratio of daylight factor satisfying criteria Ra and natural lighting illumination energy saving rate, which influenced by different window-wall ratio, windowsill height, physical dimension and glass transmittance, are analyzed roundly. The results show that the standard values of daylight factor are maximized at windowsill height 0.8m for arbitrary window-wall ratio and window physical dimension. The window-wall ratio should be controlled around 30% and aspect ratio in the range of 1~2, and the orientation sort of natural lighting illumination energy saving rate is south >east>west>south for window-wall ratio greater than 15%.
