摘　　要：本文以江苏省无锡市某零碳展示馆为例,运用极差分析和灰色关联分析等方法,量化屋顶、外墙和外窗对建筑节能的影响程度,以年均成本为评价指标,确定围护结构最优设计方案。研究结果表明,外窗影响程度最高,屋顶次之,外墙最低;计算可得设计建筑最优设计方案为屋顶、外墙和外窗的传热系数值分别为0.25W/(m^(2)·K)、0.20W/(m^(2)·K)以及1.20W/(m^(2)·K)。相较于常规设计方案,最优设计方案的年均成本减少了463元,本体节能率增加3.38%,年碳排放量减少0.79tCO_(2),该方案在满足高节能要求的同时,具有更优越的经济性和环境效益。研究工作为探索夏热冬冷地区公共建筑节能设计提供了参考。This article takes a zero carbon exhibition hall in Wuxi,Jiangsu Province as an example,and uses methods such as range analysis and grey correlation analysis to quantify the impact of roofs,exterior walls,and windows on building energy efficiency.Using annual average cost as an evaluation indicator,the optimal design scheme for the enclosure structure is determined.The research results indicate that the impact of external windows is the highest,followed by the roof,and the external wall is the lowest;The optimal design scheme for the design of the building can be obtained by calculating the heat transfer coefficients of the roof,exterior walls,and exterior windows,which are 0.25W/(m2·K),0.20W/(m2·K),and 1.20W/(m2·K),respectively.Compared to the conventional design scheme,the optimal design scheme reduces the average annual cost by 463 yuan,increases the energy-saving rate of the body by 3.38%,and reduces the annual carbon emissions by 0.79 tCO2.This scheme not only meets the high energy-saving requirements,but also has superior economic and environmental benefits.The research work provides a reference for exploring the energy-saving design of public buildings in hot summer and cold winter areas.
