摘要
工程结构物化阶段的温室气体排放主要来自建筑材料和施工活动。本文对组合结构物化过程中的二氧化碳排放量进行定量计算,并提供一种把碳排放量转化为成本进行有效控制的方法。首先,选择组合结构物化阶段作为研究对象,基于BIM技术对建筑物化过程中的主要材料和设备的碳排放量进行计算研究,并开发了基于BIM的自动化碳评估系统;其次,利用欧盟碳排放交易权体系,碳排放的经济转换率将为组合结构材料生产、运输和施工活动的碳排放提供经济评价指标;最后,采用近期碳排放交易价格将碳排放量转化为成本,并进行经济分析。本文提出的方法可以有效评估组合结构物化过程中的碳排放量,对设计过程低碳材料的选择具有参考意义,为低碳装备的研究提供案例参考。
During the engineering structure materialization stage,greenhouse gas emissions predominantly arise from building materials and construction activities.This paper aims to quantify carbon emissions during the materialization of combined structures and propose a method to convert these emissions into economic costs for effective control.This study chooses combined structures materialization as the research object,the carbon emissions of the main materials and equipment in the building materialization process were calculated and studied based on BIM technology,and develops an automated carbon assessment system based on BIM.By utilizing the European Union Emissions Trading System,the economic conversion of carbon emissions offers a quantitative economic evaluation index for carbon emissions from the production,transportation,and construction activities of the combined structure.Finally,this study also incorporates recent carbon emissions trading prices to convert carbon emissions into economic costs,followed by a detailed economic analysis.The method proposed in this paper can effectively evaluate the carbon emissions during the materialization process of the combined structure,which is of reference significance for the selection of low-carbon materials in the design process,and provides case references for the research of low-carbon equipment.
