摘要
建筑工程施工阶段的碳排放是建筑全生命周期碳排放的重要组成部分,具有高强度和集中排放等特点,是建筑领域碳排放量总量计量的难点之一。以施工单位为主体,在明确界定施工阶段碳排放计量边界基础上,详细介绍了信息模型法、燃料端统计法和排放端实测法三种建筑工程施工阶段碳排放计量方法。分析表明,信息模型法可在建设工程施工开工前估算出施工过程中任意时间节点的二氧化碳实时排放量和累计排放量,从而为建设工程施工碳排放的预报、预控提供理论依据;燃料端统计法是对项目真实碳排放信息的记录,但只能作为项目后评价的依据,不能对施工阶段碳排放量进行预判,建议在工期较短的小型施工工地碳排放量计量中应用;排放端实测法时效性强且数据准确、客观、公正,可据此调整优化施工工艺流程但测量技术复杂,可在工期较长的大型施工工地碳排放计量中应用。
The carbon emission in the construction stage of construction project is an important part of the carbon emission in the whole life cycle of the building.It has the characteristics of high intensity and centralized emission,and is one of the difficulties in measuring the total carbon emission in the construction field.Taking the construction unit as the main body,on the basis of clearly defining the boundary of carbon emission measurement in the construction stage,this paper introduces in detail three carbon emission measurement methods in the construction stage of Construction Engineering:information model method,fuel end statistical method and emission end actual measurement method.The analysis shows that the information model method can estimate the real-time and cumulative carbon dioxide emissions at any time point in the construction process before the construction of the construction project,so as to provide a theoretical basis for the prediction and pre control of carbon emissions from the construction project;The fuel end statistical method is a record of the real carbon emission information of the project,but it can only be used as a basis for post project evaluation,and cannot predict the carbon emission during the construction phase.It is recommended to apply it to the carbon emission measurement of small construction sites with short construction period;The emission end actual measurement method has strong timeliness and accurate,objective and fair data,which can be used to adjust and optimize the construction process.However,the measurement technology is complex and can be applied to the carbon emission measurement of large construction sites with a long construction period.
