谈既有建筑节能改造

摘要

分析了既有建筑节能改造的必要性，针对既有建筑节能改造推广的难点，提出了具体的解决措施，并计算了既有建筑节能改造造价费用及经济效益，指出既有建筑的节能改造既提高了供热效果，又实现了节能目标。%This PaPer analyzed the necessity of existing buildings energy saving transformation,according to the Promotion difficulty of existing building energy conservation transformation,Put forward sPecific solving measures,and calculated the cost and economic benefit of existing build-ing energy conservation transformation cost,Pointed out that the existing building energy saving transformation not only imProved the heating effect,realized the energy saving target.
