基于全寿命期理论的绿色建筑碳排放研究

RESEARCH ON CARBON EMISSION OF GREEN BUILDING BASED ON LIFE CYCLE THEORY

本文在分析国内外建筑碳排放计算范围和计算方法的基础上,提出绿色建筑碳排放应包括全寿命期运行碳排放和隐含碳排放的观点。同时,笔者团队基于生命周期理论和碳排放因子法,建立了绿色建筑碳排放计算模型,开发了单机计算软件,并针对不同气候区典型绿色居住建筑和办公建筑碳排放进行了计算和分析。结果表明:与常规节能建筑相比,各气候区绿色建筑均能大幅降低碳排放,而且绿色建筑星级越高,碳减排量越高,不同技术措施对绿色建筑的碳减排贡献率受气候区和建筑类型的影响较大。

Based on the analysis of calculation range and methods of carbon emission of green building at home and abroad,the view that green building carbon emissions include full life cycle carbon emission and embodied carbon emission is proposed.Furthermore,the carbon emission calculation model of green building is established based on life cycle theory and carbon emission factor method,and a calculation software based on personal computer is developed.The carbon emission of typical green residential buildings and office buildings in different climate zones is calculated and analyzed.The results show that in all climate zones,green building achieves greater carbon emission reduction than conventional energy-saving building.The higher star level of green buildings has greater contribution to the carbon emission reduction.The carbon emission reduction effect of implementing different technical measures is greatly influenced by climate zones and building types.
