摘　　要：工业建筑屋顶天窗面积对室内光热环境影响很大,本文针对夏热冬冷地区自然通风类工业建筑,选取武汉为代表城市,利用能耗软件EnergyPlus和采光模拟软件Radiance分别对工业建筑进行室内热环境模拟和自然采光模拟。分析了不同窗墙面积比条件下屋顶天窗面积对室内热环境的影响,并以参考平面自然采光平均照度值为评价标准,针对采光等级要求为Ⅲ级和Ⅳ级的自然通风类工业建筑,对屋顶天窗面积比进行优化,给出工业建筑在不同窗墙面积比下屋顶天窗面积比的推荐值,为工业建筑屋顶天窗优化设计提供依据。The roof skylights area of industrial buildings has a great influence on the daylighting and thermal environment.EnergyPlus and Radiance were used to simulate indoor thermal environment and natural lighting in industrial buildings.The influence of roof skylights on indoor thermal environment was analyzed.In order to optimize the skylight to roof ratio,natural ventilation industrial buildings with grade III and IV requirements for daylighting in Wuhan of hot summer and cold winter zone is selected,and the average illuminance value of natural lighting on the reference plane was chosen as the objective function.The recommended value of skylight to roof ratio of industrial buildings under different window to wall ratio is given.The information can provide basis for optimal design of roof skylights for industrial buildings.
