三、模拟概述依据《建筑采光设计标准》GB50033-2013规定，采光系数是基于全阴天模型计算而得到的，全阴天即天空全部被云层遮蔽的天气，此时室外天然光均为天空扩散光，其天空亮度分布相对稳定，天顶亮度为地平线附近亮度的三倍。3.1原理概要建筑室内参考平面上某一点的采光系数，可按下式计算：C=（En／Ew）×100%式中：En——在全阴天空漫射光照射下，室内给定平面上的某一点由天空漫射光所产生的照度(lx)；Ew——在全阴天空漫射光照射下，与室内某一点照度同一时间、同一地点，在室外无遮挡水平面上由天空漫射光所产生的室外照度(lx)。3.2分析软件本报告主要采用PKPM建筑天然采光模拟分析软件进行建模和室内采光计算，分析判断室内主要功能空间的采光效果是否达到《建筑采光设计标准》GB50033-2013的要求。对于采光系数的计算，本软件采用国标公式法计算。计算公式如下：3.2.1侧面采光系数计算式1-1：式1-2：式1-3：式1-4：式中：3.2.2顶部采光系数计算式1：式中：3.3参数设置材料的材质、颜色、表面状况决定光的吸收、反射与投射性能，对建筑采光影响较大，模拟分析时需根据实际材料性状对参数进行选值。本报告参考《建筑采光设计标准》GB50033-2013的表5.0.4及附录D和《全国民用建筑工程设计技术措施节能专篇-建筑》中表6.3.1对各种不同材料构造的光学性能参数提供的参考指导值进行赋值计算分析，本项目玻璃及内饰面材料光学性能参数取值具体如下表所示。表4材料光学性能参数构造部位材料内饰面反射比可见光透射比墙面1水泥砂浆抹面0.32--顶棚1水泥砂浆抹面0.32--地板1水泥砂浆抹面0.32--外窗16中透光Low-E+9A+6透明--0.62阳台窗16中透光Low-E+9A+6透明--0.62
