摘要
窗墙比不仅影响建筑的美观、采光,更会对建筑冷热负荷产生重大影响.本文以青岛地区1个典型办公建筑为例,利用DeST建筑热模拟软件,建立典型办公建筑模型,采用正交试验设计方法,对不同因素水平下的建筑模型进行热模拟,研究不同朝向和窗墙比对建筑负荷的影响.结果表明,对建筑负荷影响较大的朝向排列顺序依次为:东西向、南向和北向,进一步得出适宜的南向、东西向、北向窗墙比分别为0.38、0.36、0.23.本文的研究结果在JGJ 26-2010《严寒和寒冷地区居住建筑节能设计标准》的基础上,为公共建筑合理窗墙比的确定提供有益的借鉴.
Abstract
Wall-window ratio not only affects architectural appearance and lighting,but also has a significant impact on the cooling and heating load of a building.Taking a typical office building in Qingdao area as an example,this paper established a typical office building model using DeST,and then conducted an orthogonal experiment for thermal simulation of this building under the action of different factors,to explore the building load caused by different orientations and wall-window ratios.The simulation result shows that the significant orientation arrangements that affected building load included east-west orientation,southward orientation and northward orientation in a descending sequence.The best wall-window ratio southward equaled 0.38,east-westward equaled 0.36,and northward equaled 0.23.The result could be used as a beneficial reference for the selection of a wall-window ratio in public buildings on the basis of JGJ 26-2010 Design Standard for Energy Efficiency of Residential Buildings in Severe Cold and Cold Zones.
