北京市老旧小区能效测评数据的研究与分析

Research and Analysis of Energy Efficiency Evaluation Data of Old Residential Areas in Beijing

笔者通过对北京市某小区32栋,3类建筑开展能效测评,小区内建筑的相对节能率在8.51%-28.31%之间,远低于目前北京市新建建筑节能75%的设计要求,笔者给出简易节能建议即外墙加装保温;窗户需要更换为65节能窗及以上;大门需要更换为65节能门及以上。能效测评工作旨在为老旧小区改造提供精准的能耗数据及改造方向,后续节能改造提供有力依据。

Based on the energy efficiency evaluation of 32 buildings andwith 3 typesofbuildings in a residential area in Beijing, the relative energy efficiency rate of buildings in the residential area is between 8.51% and 28.31%, which is far lower than the current design requirement of 75% energy efficiency of new buildings in Beijing. The author puts forward a simple energy-saving proposal, that is,to installing thermal insulation on the external wall, replace;with theWindowsneedtobereplacedwith 65 energy-saving windows and above as well as;Thegateneedstobereplacedwiththe 65 energysaving doors and above. The purpose of energy efficiency evaluation is to provide accurate energy consumption data and transformation direction for the transformation of old residential areas, and providelay a strong basis for subsequent energy-saving transformation.
