国内外建筑生命周期碳排放评价研究进展

Research Progress of Building Life Cycle Carbon Emission Assessment

摘要: 建筑业一直是全世界能源消耗和温室气体排放的主要领域，评价建筑生命周期碳排放对研究建筑环境影响、减轻环境污染具有重要意义。本文概述了国内外建筑碳排放情况及相关政策规范，介绍了目前建筑生命周期碳排放评价方法、相关基础数据库及主要依据标准，通过借鉴国际建筑领域的相关经验，总结了我国建筑生命周期碳排放评价存在的问题，并提出了今后建筑生命周期碳排放评价中的研究重点。

Abstract: The construction industry is the main area of energy consumptions and greenhouse gas emissions in the world. It is of important significance to assess the life cycle carbon emission from buildings for reducing their environ-mental impacts. In this paper, the carbon emission status and the related policies and regulations of buildings are firstly introduced and then the assessment method, underlying database and main related standards of building lifecycle carbon emissions at home and abroad are reviewed. Furthermore, the paper summarizes the existing problems of lifecycle car-bon emissions from buildings in China and presents the research directions and emphasis according to the national con-ditions and the international experiences in the field.
