摘　　要：选取成都、会理两地,针对居住建筑在不同外立面条件下,对建筑能耗展开相关模拟计算,研究外立面吸收系数对建筑能耗影响规律。研究结果表明,(1)建筑外墙饰面材料的不同对建筑能耗的影响较屋面更为显著;(2)若建筑仅考虑空调,则两地建筑饰面材料宜选用吸收系数较小的,若建筑同时考虑空调及采暖,在会理地区外墙不宜选取辐射系数大于0.7的材料,成都地区可不作考虑;(3)屋面饰面材料选取对建筑该部分能耗影响较小,两地都可适当放宽,研究结果可为该类建筑工程设计及街道立面改造提供参考。Chengdu and Huili are selected to carry out relevant simulation calculation for building energy consumption under different facade conditions of residential buildings,so as to study the influence rule of facade absorption coefficient on building energy consumption.the result of research shows that,(1)the influence of exterior wall finishing materials on building energy consumption is more significant than that of roof;(2)If only air conditioning is considered in the building,the materials with low absorption coefficient should be selected for the building decoration.If air conditioning and heating are considered in the building at the same time,materials with radiation coefficient greater than 0.7 should not be selected for the external wall in the Huili area,and it is not considered in Chengdu area;(3)The selection of roofing finishing materials has little influence on the energy consumption of this part of the building,and it can be relaxed in both places.The research results can provide reference for the design of this kind of building engineering and street facade reconstruction.
