既有采暖居住建筑节能改造是降低建筑能耗的一个重要途径,节能改造的技术主要从建筑节能和采暖系统节能改造两方面入手。建筑节能改造主要考虑建筑围护结构的节能改造和可再生能源的利用。改造技术措施采取的合理与否对围护结构的节能改造综合效益起着关键性的作用。对围护结构墙体在节能改造时,需要考虑的改造技术措施给予分析,提出既有建筑围护结构墙体节能改造采取的一些技术措施。
Energy-saving retrofit of existing residential buildings is an important way to reduce energy consumption of buildings. The technology of energy-saving retrofits mainly focuses on two aspects: building energy-saving and energy-saving retrofit of heating system. Energy-saving renovation of buildings mainly considers the energy-saving renovation of building envelope and the utilization of renewable energy. The reasonableness of the technological measures taken to retrofit plays a key role in the overall efficiency of the energy conservation retrofitting of the envelope structure. In the energy-saving retrofit of the enveloping wall, the technical measures to be considered for the retrofitting are given, and some technical measures taken to retrofit the enveloping wall of the existing building are proposed.
