建筑工程施工阶段碳排放计算方法适用性分析

Analysis of the Applicability of Carbon Emission Calculation Methods in the Construction Phase of Building Projects

立足建筑工程节能减碳工作,分析识别建筑施工过程中的碳排放来源,列举并对比分析了目前应用较多的国际碳排放计算标准和5种建筑碳排放计算方法—实测法、投入产出法、物料均衡法、排放系数法、生命周期法。详细介绍了各计算方法的计算原理、适用范围、计算流程等内容,结合各计算方法的优缺点,给出各自的适用要求,为建筑行业在碳排放计算方面的工作提供参考。

Based on the work of energy saving and carbon reduction in construction projects,we analyze and identify the sources of carbon emission in the process of building construction,list and comparatively analyze the international carbon emission calculation standards and five methods of calculating carbon emission in buildings,namely,the actual measurement method,the input-output method,the material balancing method,the emission coefficient method,and the life-cycle method,and introduce the calculation principles and scope of application of each calculation method in detail.The calculation principle,scope of application and calculation process of each calculation method are introduced in detail,and the advantages and disadvantages of each calculation method are combined to give the applicable requirements of each method,which can provide a reference for the work of the construction industry in the calculation of carbon emissions.
