欧盟建筑物节能管理法规解读及节能管理行为分析

Interpretation of EU Building Energy Conservation Management Regulations and Analysis on Energy Efficiency Management Behavior

在欧盟,建筑因占到40%的能源消耗和35%的温室气体排放而成为最大的能源消耗来源。目前,欧盟约35%的建筑物使用年限已经超过50年,约75%的存量建筑属于低能效建筑,但每年却只有0.4%~1.2%(取决于不同成员国家)的建筑翻新率。因此,建筑节能成为欧盟实现其减排目标的优先发展领域,它可以将欧盟的总能源消耗降低5%~6%,将CO_(2)排放降低约5%,并在清洁能源转型中发挥关键作用。重点介绍了欧盟的建筑能效指令和德国在近零能耗建筑方面的实践成果,并提出对提升国内建筑能效的发展建议。

In the European Union,buildings account for 40%of energy consumption and 35%of greenhouse gas emissions,making them the largest source of energy consumption.Currently,about 35%of buildings in the EU have a service life of more than 50 years,and about 75%of existing buildings are low energy buildings,but only 0.4%to 1.2%(depending on different member countries)of buildings are renovated every year.Therefore,building energy efficiency has become a priority development area for the EU to achieve its emission reduction targets,which can reduce the total energy consumption in the EU by 5%to 6%,reduce CO_(2)emissions by about 5%,and play a key role in the clean energy transition.This article focuses on the EU's Building Energy Efficiency Directive and Germany's practical achievements in near-zero energy buildings,and proposes development suggestions for improving domestic building energy efficiency.
