摘要
外墙作为建筑的围护结构是建筑与外界环境进行热交换的主要部分。为探明外墙构造对建筑节能率的影响规律,在全面调研分析江苏省夏热冬冷地区已建居住建筑外墙构造信息的基础上,利用PKPM能效测评软件分别模拟研究外墙基体材料、保温材料及规格对模型建筑相对节能率的影响,从而为指导65%节能形势下外墙保温构造的选择应用提供技术依据。
As the main part of the building envelope, exterior wall is the main medium to realize heat exchange be-tween the building and the outside environment. In order to find out the influence of exterior wall structure on build-ing energy efficiency, this paper investigates the external wall structure information of residential buildings in thehot-summer and cold-winter area of Jiangsu province. Based on the survey and analysis, the effect of external wallmatrix material, heat preservation material and size on the relative energy saving rate of the model building is simu-lated by using PKPM software. The results provide the technical basis for the selection of external wall thermal insu-lation structure under the guidance of 65% energy saving situation.
