Carbon Reduction Measures and Cost Analysis for Construction Site of Prefabricated Building

开展建造阶段碳排放测算不仅可以作为城乡建设领域政策制定的数据支撑,而且对于落实碳达峰碳中和工作部署,探索城乡建设领域碳达峰路径,提升城乡建设绿色低碳发展质量,具有重要的工程实践价值。本文以某公共建筑为例,采用碳排放因子法对研究案例施工现场碳排放进行测算,并分析三类减碳措施对于施工现场碳排放量的影响。测算边界内,研究案例共产生149.69tCO_(2),单位建筑面积碳排放强度为5.20kgCO_(2);研究案例积极实施减碳措施,共计减少25.55tCO_(2),单位减碳成本为371.90 kgCO_(2)/万元。

The carbon emission calculation in the construction phase can not only be used as the data support for policy-making in the field of ur­ban-rural construction,but also has important practical engineering value for implementing the work deployment of carbon peaking and carbon neu­trality,exploring the path of carbon peaking in the field of urban and rural construction,and improving the green and low-carbon development quality of urban and rural construction.This paper uses the carbon emission factor method to calculate the carbon emissions for construction period of a public building,and takes three types of carbon reduction measures to effectively reduce the carbon emissions of construction sites.It is estimated that 149.69tCO_(2) is generated within the boundary,and the carbon emission intensity per unit floor area is 5.20 kgCO_(2).The study case actively implement­ed carbon reduction measures,reducing 25.55 tCO_(2) in total,with a unit carbon reduction cost of 371.90 kgCO_(2)/10,000 RMB.
