随着人们生活水平的提高,居住建筑能耗日益增大,然而贵州地区大量既有居住建筑外窗热工性能差,导致采暖空调能耗浪费现象严重。本文主要研究不同外窗改造方式的技术特点和经济成本,并通过软件模拟计算的方法分析节能效果及投资回收期,提出适宜的改造方式,为贵州地区既有居住建筑外窗改造提供思路方法和参考数据。
With the improvement of people’s living standards, the energy consumption of residential buildings is increasing day by day. However, the thermal performance of a large number of existing residential building windows in Guizhou is poor, leading to a serious waste of energy and waste of heating and air conditioning. This paper mainly studies the technical characteristics and economic cost of different exterior windows retrofit methods, and analyzes the energy-saving effect and payback period through software simulation calculation method, puts forward the appropriate retrofit methods to provide ideas and methods for the reconstruction of exterior windows of existing residential buildings in Guizhou Reference data
