中芬居住建筑生命周期碳排放测算及环境影响对比研究

A Comparative Study of Carbon Emission Calculations and Environmental Impacts in the Life Cycle Assessment of Residential Buildings in China and Finland

在碳达峰和碳中和战略目标下,低碳建筑研究愈加重要,而我国当前对于建筑的碳排放定量研究尚相对薄弱。本文基于LCA理论,通过引入ONE-CLICK LCA软件,对中、芬两国代表性居住建筑进行了全生命周期碳排放计算和实证对比分析,结果表明冬季清洁取暖、使用胶合木等环境友好的生态材料、延长建筑使用周期有利于降低建筑全生命周期碳排放。

With the implementation of China’s carbon peak and neutrality strategic goals,there is an urgent need to deepen the research on low-carbon buildings.In contrast,the quantitative analysis of carbon emissions from buildings in China is relatively insufficient.Based on the LCA theory,this paper calculates the carbon emissions of life cycle assessment(LCA)and conducts a comparative empirical analysis of two representative residential buildings in China and Finland through the software ONE-CLICK LCA.The results show that clean heating in winter,environmentally friendly materials such as CLT,and extended service life are conducive to reducing carbon emissions throughout the life cycle of buildings.
