摘　　要：为降低江西省居住建筑能耗,助力江西省碳达峰实施,基于江西地区某高校新建学生宿舍,利用DesignBuilder软件,从建筑运行阶段的角度对能耗影响因素进行分析。选取建筑朝向、建筑层高、屋顶形式、外墙传热系数、窗墙比五项因素进行能耗模拟比较,通过单因素分析和正交试验法,研究不同因素对建筑能耗的影响趋势以及其显著性特征,研究结果表明建筑朝向为正南方向,建筑层高2.7 m,屋顶形式为平屋顶,外墙传热系数为0.3 W/(m^(2)·K),窗墙比为0.3是最优节能组合方案,经过模拟确认了最优方案的单位面积能耗为52.64 kW·h/m^(2),比当前建筑设计节能24.7%。结果为江西省宿舍建筑节能设计提供了明确方向,对建筑碳达峰实施有一定意义。To reduce the energy consumption of residential buildings in Jiangxi Province and assist to the implementation of carbon peak in Jiangxi Province,based on the new student dormitory of a university in Jiangxi Province,DesignBuilder software was used to analyze the factors affecting energy consumption from the perspective of building operation stage.The results show that the building is facing due south,the building floor height is 2.7 m,the roof form is flat roof,and the heat transfer coefficient of the exterior wall is 0.3 W/(m^(2)·K).The window-to-wall ratio of 0.3 is the optimal energy-saving combination scheme,and the energy consumption per unit area of the simulated optimal scheme is 52.64 kW·h/m^(2),which is 24.7%energy saving than the current building design.The research results provide a clear direction for the energy-saving design of dormitory buildings in Jiangxi Province,which has certain significance for the implementation of building carbon peaking.
