摘　　要：在建筑行业,进行建筑室外保温设计计算是减少建筑能耗的重要途径之一。文章针对建筑围护物的室外保温设计计算问题,提出了一种参数优化方法。过程中对建筑围护物结构进行分析,从3个角度进行热阻最小值计算方式的设计,并选取了参数更新使用的主要参数。实验结果表明,研究方法在进行采暖室外计算温度分析时,得到结果有20.60%站点的温度出现上升;在房间地面热阻变化分析中,采暖房间中10个站点的地面热阻上升达到标准限值;在墙体保温热阻变化分析中,温度较低地区的房间更新后的热阻区间为0.67~1.32m^(2)K/W。说明研究方法能有效对室外保温设计计算方法参数进行优化更新。In the construction industry,conducting outdoor insulation design calculations is one of the important ways to reduce building energy consumption.A parameter optimization method is proposed to study the calculation of outdoor insulation design for building envelopes.During the process,the structure of the building envelope is analyzed,and the calculation method for the minimum thermal resistance is designed from three perspectives.The main parameters used for parameter updates are selected.The experimental results show that when the research method is used for outdoor temperature analysis of heating,20.60%of the stations show an increase in temperature.In the analysis of changes in room ground thermal resistance,it is found that the ground thermal resistance of 10 stations in the heating room had risen to the standard limit.In the analysis of changes in wall insulation thermal resistance,the updated thermal resistance range for rooms in lower temperature areas is 0.67m^(2)K/W to 1.32m^(2)K/W.This indicates that the research method can effectively optimize and update the parameters of outdoor insulation design calculation methods.
