基于BIM的建筑LCA测算研究

Research on Building LCA Calculation Based on BIM

本文基于测算建筑全生命周期的碳排放量,依据《DBT 51366-2019建筑碳排放计算标准》中碳排放量计算体系,选取武汉工程科技学院18#学生公寓进行碳排放量测算。通过对建筑物的全生命周期进行评估,精准地估算出全过程的碳排放量。将建筑物的生产、施工、运营和拆除过程划分为不同的阶段,并利用LCA(生命周期评估法)的基本原理来确定每个阶段的碳排放量。

Based on measuring the carbon emissions of the whole life cycle of the building,this paper selects the 18#student apartment of Wuhan University of Engineering Science to measure the carbon emissions based on the carbon emission calculation system in the DBT 51366-2019 Building Carbon Emission Calculation Standard.By evaluating the whole life cycle of the building,the carbon emissions of the whole process were accurately estimated.The process of production,construction,operation and demolition of the building was divided into different stages,and the basic principles of LCA(Life Cycle Assessment)were utilized to determine the carbon emissions of each stage.
