本文采用南京地区典型气象年逐时数据,运用eQUEST能耗模拟软件分析了南京地区办公楼采用低辐射玻璃外窗对建筑能耗的影响。研究表明该地区采用遮阳型低辐射玻璃外窗要优于高透型低辐射玻璃外窗;采用可翻转窗技术可改变外窗的光热性能,降低建筑供暖能耗,从而进一步提高低辐射玻璃外窗的全年节能效果;由遮阳型和高透型低辐射玻璃外窗的分析比较可知,Low-E面置于室内侧的遮阳型低辐射玻璃外窗更适用于南京地区。
In this paper, the annual meteorological year-by-hour data of Nanjing were used. The eQUEST energy consumption simulation software was used to analyze the influence of low-emissivity glass windows on building energy consumption in Nanjing office buildings. Research shows that the use of shaded low-emissivity glass outer windows in the region is superior to that of high-penetration low-emissivity glass windows; the use of the switchable window technology can change the solar thermal performance of the outer windows and reduce the building heating energy consumption, thereby further improving the low-emissivity glass Outside the window of the year energy-saving effect; by shading and translucent low-E glass outside the window analysis and comparison shows that the Low-E surface placed on the indoor side of the sunshade low-E glass outer window is more suitable for the Nanjing area.
