建设项目施工过程中会排放出大量温室气体,因此施工建造阶段是建筑全生命周期排放评估中的重要组成部分。本文基于建筑全生命周期理论(Life Cycle Assessment,LCA),结合绿色施工评价框架和施工管理技术,以施工单位为主体界定了施工阶段温室气体排放核算范围;以施工单元过程为核心,施工项目分级与集成为辅助,建立了其清单分析过程;并在以上工作基础上,构建了施工阶段温室气体排放核算数学模型,最终确立了施工阶段温室气体排放核算框架,为客观鉴别施工活动的碳排放情况奠定了基础。
Construction projects will emit a large amount of greenhouse gases during construction. Therefore, the construction phase is an important part of the assessment of the entire life cycle of buildings. Based on the LCA (Life Cycle Assessment), combined with the green construction evaluation framework and construction management techniques, this paper defines the scope of GHG emission accounting during the construction stage with the construction unit as the main body. With the construction unit process as the core, the construction project is graded And set up its inventory analysis process. On the basis of the above work, a mathematical model of GHG emission accounting during the construction phase was constructed, and the framework of GHG emission accounting during the construction phase was finally established. In order to objectively identify the carbon emission of construction activities Foundation.
