摘　　要：使用Trnsys和De ST软件计算了某超低能耗建筑的全年采暖能耗和空调能耗总和分别为67054.03 k Wh和61915.84 k Wh,偏差为8.3%在合理范围内;使用Trnsys比较分析了高保温外墙在沈阳、广州两座城市的节能效果,研究发现,高保温外墙在沈阳地区的节能提升率达44.9%,而其在广州地区的节能效果有限,节能率仅为17.2%。Using the software Trnsys and DeST to establish a computational model of an ultralow energy building,the differences between these two results was compared.Adjusting the heat transfer coefficient of high-insulation wall to the conventional level of insulation,the high insulation effect of exterior wall between Shenyang and Guangzhou City was compared and analyzed.As the research shows,the energysaving rate of the high-thermal insulation wall in Shenyang can reach 44.9%.While its energy-saving effect in Guangzhou is limited,and the energy-saving rate is 17.2%.
