摘　　要：本文以北京市某南向办公建筑为研究对象,考虑了影响建筑围护结构得热量的六个建筑设计因素:窗墙面积比、外窗的类型、水平遮阳板尺寸、外墙的结构类型、屋顶的结构类型及房间尺寸(长/高/宽)。通过正交试验和EnergyPlus模拟,找出了在夏季自然通风建筑设计中,围护结构总得热量随各设计因素的变化趋势,并得出使建筑围护结构总得热量相对最低的六个建筑因素的最佳搭配。结果表明,北京地区通过改善围护结构的保温性能和合理的建筑设计,能够有效降低建筑能耗。Six affecting factors of architecture on heat gain of the envelope are considered, such as, area ratio of window to wall, characteristics of window, dimensions of shade, characteristics of external wall, characteristics of roof and dimensions （length / height / width） of the room. The optimal combination of these six factors is obtained by EnergyPlus simulation and orthogonal experimental method in order to get a better natural ventilation building thermal environment with lower heat gain of the envelopes. The results reveal that improving buildings envelope condition helps to reduce buildings energy consumption.
