摘　　要：目前,建筑运行能耗在建筑能源消耗中占比较大。为寻求夏热冬暖地区对建筑节能最有利的建筑外墙,基于GB 55015—2021,对采用不同典型外墙构造的设计与参照建筑进行仿真模拟,分析不同窗墙比对建筑冷负荷与过渡季节自然室温的影响。结果表明:外墙主要构造材料是影响围护结构节能率最主要的原因;同时建筑外墙传热系数不应一味减小,还应考虑室内夜间散热问题。对于2022年4月1日后的新建建筑,应优先采用主体构造为页岩烧结多孔砖(240 mm)的典型建筑外墙,对建筑节能最有利。At present,building operation energy consumption accounts for a large proportion of building energy consumption.The purpose of this paper is to seek the most favorable building exterior wall for building energy conservation in hot summer and warm winter areas.Based on the newly released standard GB 55015—2021,it simulates the design and reference buildings of typi-cal external walls.The influence of different exterior wall on building cooling load and natural room temperature in transition sea-son is analyzed under different window-wall ratio.The results show that the difference of main construction materials is the main reason for the energy-saving rate of envelope structure.The heat transfer coefficient of exterior wall should not be reduced blindly,and the indoor heat dissipation at night should also be considered.For new buildings after April 1,2022,the typical building exte-rior wall of burned shale perforated brick(240 mm)should be preferred and it is most beneficial to building energy conservation.
