摘　　要：以广州为例,利用DeST-C和DeST-H分析围护结构热工参数现阶段对广东地区公共建筑和居住建筑的空调冷负荷的影响规律,回答是否有必要一味降低相关规范中围护结构传热系数限值,并通过情景分析在2032年考虑气温升高下的影响规律变化。结果表明,现阶段的节能设计标准制定,无需降低外墙、屋面、外窗的传热系数限值;在未来阶段,需要提高对外窗的热工参数的要求,并适当降低居住建筑的外墙传热系数限值。DeST-C and DeST-H are utilized to analyze the influence of the thermal parameters of the enclosure structure on the air conditioning cooling load of the public buildings and residential buildings in Guangdong in order to answer whether it is necessary to reduce the limit of the heat transfer coefficient of the enclosure structure in the relevant specifications, and the change of influence rule under the rising temperature in 2032 is analyzed through scenario analysis. The results show that the current energy saving design standard is not required to reduce the heat transfer coefficient of exterior wall, roof and outer window. In the future, it is necessary to improve the thermal parameters of external windows and appropriately reduce the heat transfer coefficient limit of residential building exterior wall.
