Fundamental Calculation of Carbon Emission Primitives in Construction Phase of Building Projects

碳排放计算是实现建筑施工碳减排的重要环节,有利于建筑业低碳化发展。为解决建筑工程施工阶段碳排放量化复杂的问题,文章考虑建筑工程的阶段性特点,将碳排放计算的清单分析法与建筑工程的施工工艺结合,建立了建筑工程施工阶段碳排放的基元化计算方法,并对江苏省南京市中江建筑智慧产业园项目进行碳排放计算,分析分部工程和人工材料机械的碳排放构成,为建筑工程施工阶段碳排放基元化计算方法的应用推广提供参考。

Carbon emission calculation is a crucial aspect in achieving carbon reduction during construction in the building sector,contributing to the industry's low-carbon development.To address the complexity of quantifying carbon emissions during the construction phase of building projects,this study takes into consideration the phased characteristics of construction projects.By integrating the inventory analysis method for carbon emission calculation with the construction processes of building projects,a fundamental calculation approach for carbon emissions during the construction phase of building projects is established.This approach is then applied to calculate carbon emissions for the Zhongjiang Smart Industrial Park construction project in Nanjing,Jiangsu Province.The analysis dissects the carbon emissions composition of sub-projects,as well as human labor,materials,and machinery,providing valuable insights for the widespread application of the fundamental calculation method for carbon emissions during the construction phase of building projects.
