摘　　要：围护结构冷负荷是建筑冷负荷的重要组成部分。传统的建筑围护结构冷负荷计算方法需要大量详细的建筑信息。城市规划阶段通过控制性详细规划只能获得建筑功能、建筑高度、容积率等有限的信息,限制了传统方法的应用。本文结合城市规划阶段特点,依据建筑体形系数及窗墙比的不同取值,将公共建筑划分为24类,提出了公共建筑围护结构冷负荷的简单计算方法。以北京地区为例,对每一类建筑进行了不同底面边长及高度条件时的建筑围护结构冷负荷计算,提出了适用于北京地区的简单估算公式,并分析了建筑围护结构冷负荷与建筑底面边长、建筑高度及建筑体形系数的关系。Envelope cooling load is an important part of building cooling load.Traditional calculation methods to building envelope cooling load require a large number of detailed building information.However,the limited information can only be controlled in the urban planning stage,such as building function,building height,floor area ratio and so on.All of that limits the application of traditional methods.In this paper,the public building is divided into 24 types according to the characteristics of urban planning stage,the different values of building shape coefficient and the window wall ratio.A simple method to estimate public building envelope cooling load is proposed.Take Beijing for example,a simple estimation formula for each type of building is proposed.The relationship between building envelope cooling load and the bottom side of building,building height and shape coefficient is analyzed.
