摘　　要：建筑工程在施工过程中消耗大量资源、能源的同时,也产生大量的固体废弃物和温室气体排放。本文通过研究民用建筑工程建设过程中温室气体排放的测算方法,通过生命周期评价法(LCA)对民用建筑工程施工期碳排放进行量化分析,将建筑工程按工程性质分为基础工程、结构工程、装修工程、安装工程和施工临设,厘清各部分碳排放源及碳排放因子。在案例分析中发现,工程项目临时设施的碳排放量占建筑结构本身建设碳排放量的1/5左右,为实现施工期的减排措施提供了针对性依据。Buildings consume a large amount of resources and energy in the construction process and produce a large number of solid waste and greenhouse gas emissions. In order to identify the calculation method of greenhouse gas emissions, the life cycle assessment （LCA） is used to quantitatively analyze the carbon emissions during the construction process of civil building projects. The civil building projects are divided into foundation engineering, structural engineering, decoration works, installation works and temporary facilities, to clarify the various parts of carbon emissions sources and carbon emission factors. In the case study, it is found that the carbon emissions of temporary structure in the construction project accounts for about 1/5 of the total carbon emissions of the building structure itself,, providing a targeted basis for the implementation of emission reduction measures during the construction period.
