摘要
通过测试改造前后外窗的物理性能(气密性)、冬季采暖时室内外温度、室内房间噪声及建筑物外立面窗口红外热检测等内容,根据测试结果,将改造前和改造后的数据进行对比,对其既有建筑外窗改造后的节能效果进行分析,分析显示,在既有外窗基础上安装密封条和把单玻窗户更换为双玻窗户的改造形式,节能效果显著。
Physical properties （air tightness） of external window, indoor and outdoor temperatures during heating in winter, indoor noise and infrared thermographic inspection of windows on external facade of building, etc. before and after window rebuilding are tested, and the data before and after rebuilding are compared according to the test results, to analyze the energy efficiency of external windows of existing buildings after rebuilding. The analysis result indicates that installation of sealing strip on existing external window and change of single-layer glass window into double-layer glass window may obtain obvious energy efficiency.
