摘　　要：外围护结构的热工性能直接影响建筑能耗。为寻找有利于夏热冬冷地区模块化钢结构居住建筑的外墙,基于某典型乡村住宅项目,对采用6种外墙的设计建筑和参照建筑进行全年能耗模拟,分析建筑能耗差异。结果显示,保温模卡砌块砌体墙和水泥纤维板轻钢龙骨组合墙对模块化钢结构建筑节能更有利,保温材料及其厚度显著影响节能效果,不同外墙的的参照建筑热工参数不同时无法以围护结构节能率简单反映外墙的节能效果差异,为类似项目的外墙选型提供参考。The thermal performance of the external envelope directly affects the building energy consumption.In order to find a favourable façade for modular steel-framed residential buildings in hot-summer and cold-winter regions,based on a typical rural residential project,annual energy consumption simulations were carried out for the design building and the reference building with six types of façades to analyse the differences in building energy consumption.The results show that insulated moulded card block masonry wall and cement fibre board light steel keel combination wall are more beneficial to the modular steel structure building energy saving,the insulation material and its thickness significantly affect the energy saving effect,and the thermal parameters of the reference buildings with different external walls are different while it is not possible to reflect the difference in energy saving effect of the external walls by the energy saving rate of the enclosure structure in a simple way,so as to provide references for the selection of the external walls of the similar projects.
