基于LCA的建筑碳排放计算及减排策略研究——以某住宅工程为例

Research on Building Carbon Emission Calculation and Emission Reduction Strategies Based on LCA:Taking a Residential Project as an Example

借鉴LCA原则与框架及相关学者的研究成果,将建筑整个生命周期划分为建材生产及运输、施工建造、建筑物运行及拆除处理四个阶段,并界定建筑全生命周期各阶段的主要碳排放来源。运用东禾建筑碳排放计算软件,以江苏地区某高层钢筋混凝土结构住宅楼为例,计算其各阶段及全生命周期的碳排放量,并提出相应的碳减排对策,为建筑行业实现“双碳”目标提供借鉴和参考。

Based on the principles and framework of Life Cycle Assessment(LCA)and the research results of scholars,the whole life cycle of a building is divided into four stages:building material production and transportation,construction,operation and maintenance and demolition treatment,and defines the main carbon emission sources of each stage of the building life cycle.Secondly,using Donghe building carbon emission calculation software,taking a multi-storey reinforced concrete residential building in Jiangsu as a case building,the carbon emission of the whole life cycle and each stage of the residential building are calculated,the corresponding emission reduction countermeasures are put forward,which providing reference for the construction industry to achieve the“double carbon”goal.
