典型博物馆建筑全生命周期碳排放核算分析

公共建筑具有能耗高、碳排放量大的特征，是建筑业重点减排对象。在传统低碳建筑研究的基础上，以全生命周期评价（LCA）的视角，将建筑碳排放分为建材生产、建材运输、建筑建造、建筑运行以及建筑拆除几个阶段，并对某博物馆建筑进行全生命周期碳排放评价，定量分析该建筑各个阶段碳排放特点。结果表明，建筑运行阶段碳排放量占总量的74.61%，建材生产阶段碳排放量占总量的20.34%，并针对性地提出降低碳排放的技术路径与措施，为之后开展相关研究提供参考。

Analysis of Life Cycle Carbon Emission Accounting of Typical Museum Buildings

With the characteristics of high energy consumption and large carbon emissions, public buildings are the key targets foremission reduction in the construction industry. Based on the traditional research of low-carbon buildings, this paper divides thecarbon emission of buildings into several stages: building materials production and transportation, building construction, operation,and demolition from the perspective of life cycle assessment, evaluates the life cycle carbon emission of the museum building, andquantitatively analyzes the carbon emission characteristics of each stage of this building. The results show that 74.61% of the total carbonemissions were emitted in the building operation stage, and 20.34% in the building materials production stage. Finally, the technicalpaths and measures to reduce carbon emissions are proposed, which can provide reference for relevant research in the future.
