摘要
利用拉丁超立方抽样方法和EnergyPlus模拟获取500组样本数据,对围护结构与以五个城市代表的五个气候区的居住建筑全年能耗的影响规律进行敏感性分析。结果得出除夏热冬暖地区外,其他地区需重点关注降低外墙和外窗的传热系数,严寒地区和寒冷地区需提高太阳得热系数,温和地区和夏热冬冷地区则适当降低太阳得热系数;夏热冬暖地区要重点降低太阳得热系数,并通过分析确定最佳外窗传热系数为3. 2 W/(m^2·K)时,最佳外墙传热系数为0. 3 W/(m^2·K)。
500 sets of sample data were obtained by using the Latin hypercube sampling method and EnergyPlus simulation,so as to make sensitivity analysis on the influence of envelope structure and energy consumption of residential buildings in five climate zones represented by five cities. The results show that in addition to the hot summer and warm winter regions,other regions need to focus on reducing the heat transfer coefficient of the external wall and windows. The cold and heat regions need to increase the solar heat gain coefficient,while the mild regions and the hot summer and cold need to reduce it appropriately. In the hot summer and warm winter region,the solar heat gain coefficient should be reduced,and the best external wall heat transfer coefficient is 0. 3 W /( m^2 ·K) when the best external window heat transfer coefficient is determined to be 3~3. 5 W /( m^2 ·K).
