摘　　要：建筑外饰面是围护结构抵御外界气候影响的第一道防线,其材料的热工性能将直接影响围护结构的热工性能。通过对围护结构传热过程的分析认为,影响外饰面材料热工性能的参数主要是表面黑度和对太阳辐射热的吸收系数。这些影响与材料的颜色、粗糙度、材质有关。用实验方法研究了北京不同墙面颜色、粗糙度、材质对墙面温度的影响,并用建筑模拟分析软件DeST分析了不同黑度和太阳辐射热吸收系数的外饰面材料对建筑能耗的影响程度。The exterior wall surface is the first protection of resisting outdoor climate. Its thermal pertormanee can affect directly the thermal performance of the exterior wall. The long wave emittances （ε） and solar radiant absorptanees （ρs） of the wall surface materials are the main factors affecting thermal performance of the wall on the analysis of heat transfer in the exterior wall in this paper. The relation of exterior wall surface temperature and the color, the roughness, the material has been studying by the experiments. The coefficients and ρs of exterior wall surface materials and the building energy consumption is analyzed by software DeST.
