With the combination of lighting, cooling and heating under daylighting, the study on the effect of the key characteristic parameters on total energy consumption is provided. The validation of the comparability of daylight distribution for building antetype and model is made through theoretical analysis and simulating calculation in the thesis. Due to the variable sky condition, daylighting factor is used for experimental validation instead of illuminance. The error analysis of several testing methods used in the experiment is conducted, followed by the experimental validation of the effect of WWR, sill and transmittance on daylighting factor distribution.

基于天空状态的多变性，提出用天然采光因数替代照度进行实验验证，对实验中的几种测试方法进行了误差分析，并通过实验验证了窗墙比、窗台高和透光率对天然采光因数分布的影响。4 为了更直观地分析各参数对照明节电的影响，提出了"特征点"、"特征线"和"特征距离"等概念；分析了天然采光下的照明节能状况，综合考虑照明、采暖和空调能耗，计算分析了几个主要特性参数对总能耗的影响。
