摘要
该文依据《建筑碳排放计算标准》(GB/T 51366—2019),并结合近年来相关研究,以二星级绿色建筑——重庆市设计院建研楼工程为例,计算了工程全生命周期碳排放量。计算得出项目全生命周期碳排放量为11633.59tCO_(2),单位面积碳排放量为3906.38kgCO_(2)/m^(2),其中运行阶段碳排放量占53.67%,建材生产与运输阶段占40.96%,建造及拆除阶段占5.37%。通过对相关计算标准、研究成果和计算数据的分析和讨论,认为《建筑碳排放计算标准》中,部分建材碳排放因子缺失,设备用能的计算、绿化碳汇计算、拆除阶段碳排放计算等方面尚待完善。研究认为,转变发展模式,避免大拆大建,采购绿色建材,利用既有建筑主体结构进行改造,采用可循环或可再利用的建材可大幅降低建材生产阶段碳排放;建材本地采购,控制土石方量及外运距离可大幅降低运输过程中的碳排放;降低空调及照明能耗可有效降低建筑运营阶段碳排放量。
Based on The Building Carbon Emission Calculation Standard GB/T 51366—2019,and combined with the relevant research in recent years,this paper took the two-star green building—the Architectural Research Center building of CQADI as a case to calculate the carbon emission of the project in the whole life cycle,which is 11,633.59 tCO_(2),and that of a unit area is 3,906.38kg CO_(2)/m^(2),with that in the operation stage accounting for 53.67%,40.96%and 5.37%in the building material production and transportation stage,and the construction and demolition stage,respectively.Through the summary and analysis of relevant calculation standards,research results and calculation data,the author believes that in The Building Carbon Emission Calculation Standard,some specific aspects need to be perfected,such as the lack of some carbon emission factors for building materials,the calculation of equipment energy consumption,the green carbon sink calculation,and the carbon emission calculation in the demolition stage.The research believes that it is necessary to change the development modes,avoid large-scale demolition and construction,purchase green building materials,use the existing building main structure for transformation,and adopt recyclable or reusable building materials,so that the carbon emissions can be greatly reduced in the production stage of building materials;what’s more,to procure building materials in local places,to control the earthwork quantity and the transportation distance can dramatically reduce the carbon emissions in the transportation process;while reducing the energy consumption of air conditioning and lighting can effectively reduce the carbon emissions in the operation stage.
