摘　　要：DB 33/1015—2021《居住建筑节能设计标准》对居住建筑外墙等性能提出更严苛的要求,直接影响建筑总体造价。如何在满足现行节能标准前提下,控制初始投资成本及投资回收期具有较强现实意义。通过调研杭州市21个居住建筑项目(共227幢单体建筑),并基于Rhino和Grasshopper平台建立一典型高层住宅外墙的遗传算法优化模型。优化结果显示,外墙在采用合理形式的复合保温构造后可在降低建筑运行能耗(降幅14.46%~16.27%),将投资回收期控制在合理范围内(13.54~15.00年),可为相似建筑设计提供参考。Db 33/1015—2021 Design standard for energy efficiency of residential buildings,which puts forward more stringent requirements for the performance of residential buildings such as external walls,directly affecting the overall building cost.How to control the initial investment cost and payback period under the premise of meeting the current energy saving standard has strong practical significance.A total of 21 residential building projects(227 individual buildings in Hongzhou)were investigated in this paper,and a genetic algorithm optimization model of exterior wall of a typical high-rise residential building was established based on Rhino and Grasshopper platforms.The optimization results show that the rational composite insulation structure can not only reduce the building operation energy consumption(14.46%~16.27%),and also control the payback period within a reasonable range(13.54~15.00 years)which can provide some reference for designers when designing similar buildings.
