摘　　要：为了降低夏热冬冷地区的建筑能耗,选取夏热冬冷地区某典型公共建筑为研究对象,基于DesignBuilder软件进行全年能耗模拟,以围护结构中的外墙、屋面、外窗的传热系数和外窗的太阳得热系数作为关键参数,分析了不同变动幅度下的参数取值方案对建筑节能量的敏感程度,并在其范围内选取参数进行正交试验。研究结果表明,外墙传热系数对建筑节能量的敏感度最高,其次分别为外窗传热系数、屋面传热系数和外窗太阳得热系数,其中外墙传热系数的建议取值范围为0.604~0.800 W/(m^(2)·K),外窗传热系数和太阳得热系数的建议取值范围分别为1.485~3.000 W/(m^(2)·K)和0.34~0.44。研究结果可为夏热冬冷地区公共建筑的节能设计提供一定的参考和借鉴。In order to reduce the energy consumption of buildings in hot summer and cold areas,a typical public building in hot summer and cold winter area is selected as the research object,and the annual energy consumption simulation is carried out based on DesignBuilder software.The heat transfer coefficient of exterior wall,roof and exterior window and the solar heat gain coefficient of exterior window are taken as the key parameters,and the sensitivity of parameter selection schemes to building energy saving under different fluctuation ranges is analyzed,and the parameters are selected in its range for orthogonal test.The results show that the heat transfer coefficient of exterior wall is the most sensitive to the energy saving of the building,followed by the external window heat transfer coefficient,roof heat transfer coefficient and the solar heat gain coefficient of exterior wall,among which the recommended value range of the exterior wall heat transfer coefficient is 0.604~0.800 W/(m^(2)·K),the recommended value range of the heat transfer coefficient and solar heat gain coefficient of the exterior window is 1.485~3.000 W/(m^(2)·K) and 0.34 to 0.44.The research results provide reference for the energy saving design of public buildings in hot summer and cold winter areas.
