摘要：

为了准确模拟计算水平式外遮阳的全年节能率,针对夏热冬冷地区居住建筑节能设计标准（JGJ 134-2010）规定的采暖计算期（90 d）过长的问题,基于相关国家标准,分析了杭州市1971~2000年的气象数据,提出新的采暖计算期（40 d）及空调计算期（81 d）,并采用Energy-Plus能耗模拟软件对水平式外遮阳的全年节能率进行模拟计算.结果表明：采用此采暖计算期及空调计算期时,水平式外遮阳的全年节能率降为3.2 %,采暖电耗与空调电耗的比值为1.07,与调查所得的比值0.95接近.
Abstract:

 In order to accurately simulate the energy saving rate of horizontal external shading, new heating and cooling periods were proposed as 40 days and 81 days respectively based on national standards and the meteorological data from 1971 to 2 000 in a typical hot summer and cold winter city of Hangzhou, for the problem of the too long heating period as 90 days specified in the national standard for residential buildings in hot summer and cold winter zone in China (JGJ 134-2010). Energy-Plus software was used to simulate the annual energy saving rate of horizontal external shading. Results show that by adopting the new heating and cooling periods, horizontal external shading reduces annual electric consumption of air conditioner by 3.2 %, and the ratio of heating electric consumption to cooling electric consumption is 1.07 which is approximate to the investigated value of 0.95.
