金杨二街坊外窗节能改造探究

Probe into energy-saving reconstruction of external windows of Jinyangerjiefang

与新建建筑相比,我国既有建筑总量巨大,且大多为非节能建筑。外窗是建筑耗能的薄弱环节,具有节能改造难度小,改造周期短,节能效果显著等特点,是既有建筑围护结构节能改造的一个重要的环节。

Compared with new buildings, the vast majority of existing buildings in our country are not energy-saving. External window is the weak link in energy con- sumption of building; the difficulty of energy-saving reconstruction is small, and recon- struction period is short, energy-saving effect is obvious and etc., and it is one impor- tant link for energy-saving reconstruction of building envelope.
