摘要
基于上海市居住建筑实际用能模式,针对典型建筑类型,通过De ST软件全年动态模拟分析外墙传热系数和吸收系数、屋面传热系数和吸收系数、外窗传热系数和遮阳系数对建筑能耗影响的敏感性系数,以确定节能重点。得出在上海地区,如果以夏季空调能耗为节能对象的建筑,其节能技术路线排序应为外窗遮阳系数、外墙太阳辐射吸收系数、外墙传热系数、屋面太阳辐射吸收系数、外窗传热系数和屋面传热系数。
Based on the actual energy use pattern in Shanghai residential buildings,according to the typical type of architecture,analyses the sensitivity coefficients of wall heat transfer coefficient and absorption coefficient,roof heat transfer coefficient and absorption coefficient,external window heat transfer coefficient and shading coefficient through the annual dynamic simulation software DeST.Concludes that in the Shanghai area,for saving building air conditioning energy consumption,the technology route sequencing should be shading coefficient of external window,wall solar radiation absorption coefficient,heat transfer coefficient of external wall,roof solar radiation absorption coefficient,heat transfer coefficient of external windows and roofing heat transfer coefficient.
