摘　　要：以海南省一典型居住建筑为对象,分析多种围护结构做法的热工性能及构造做法对建筑能耗的影响。结果表明,热带海岛地区较常使用的通风屋面由于气流堵塞已不能满足隔热节能要求,应在空气间层上方铺设泡沫玻璃或泡沫混凝土隔热层。蒸压加气混凝土隔热性能显著,建筑内表面最高温度可保持在35.59℃的较低水平,隔热反射涂料可有效降低建筑空调能耗。In this paper, a typical residential building in Hainan province is taken as example to investigate the impact of different building envelope practices on the thermal perfromances and energy consumption of the building. It is found that the commonly employed ventilation roof in tropical island cities may not satisfy the ralted standards on thermal performances and energy saving, and should be companied by a layer of foamglass or foamed concrete. Meanwhile, autoclaved aerated concrete presents favorable performances in hindering the heat tranfered from the outside, and insulattion coating can reduce the building＇s cooling demand apparently.
