摘　　要：考虑了影响建筑热环境的6个建筑设计要素:窗墙面积比、窗类型(传热系数)、水平遮阳板尺寸、外墙传热系数、屋顶传热系数及房间尺寸(长∶高∶宽)。根据设定的室内热环境评价指标:室内温度平均值、PMV平均值、温度不均匀系数和速度不均匀系数,通过正交试验和CFD模拟,得到了自然通风建筑设计中,使建筑热环境相对最优化的6个建筑设计要素的最优搭配方案。Considers the six architectural factors affecting building thermal environment such as the area ratio of window-to-wall,type of the window（heat transfer coefficient）,dimensions of the horizontal shade plate,heat transfer coefficient of the external wall,heat transfer coefficient of the roof and dimensions of the room（length∶height∶width）.Taking mean indoor temperature,mean PMV,temperature non-uniform coefficient and velocity non-uniform coefficient as the evaluating indexes of indoor thermal environment,obtains the optimal combination of the six factors by CFD simulation and orthogonal experiment method for a better indoor thermal environment for natural ventilated buildings.
