摘　　要：选取夏热冬冷地区的一栋办公楼作为研究对象,通过De ST-C软件,模拟了窗玻璃型材、窗户遮阳方式等外窗节能改造技术的建筑能耗状况,得出该区既有建筑节能改造更换窗户时不仅应考虑窗户的传热系数,而且要考虑选用小的太阳得热系数;南向不宜出挑深度大的水平遮阳板;宜选择3片~4片深度为300 mm^450 mm的水平百叶遮阳。Based on researching of energy-efficient retrofitting of representative office buildings,utilizing De ST-C software to simulate building loads of various retrofit measures,such as window materials and shading etc.. Some conclusions are obtained that not only the heat transfer coefficient of the window should be taken into account but also the small solar gain coefficient should be taken into consideration,it is not advisable to use a horizontal shading with a large depth and should choose 3 to 4 horizontal blinds with depth of 300 mm ~ 450 mm.

关 键 词：夏热冬冷地区 既有公共建筑 窗户 节能改造
