摘　　要：针对当前市场碳排放因子种类繁多、更新频率高、碳排因子使用不当的现象,全面分析了当前2大类电网二氧化碳(CO_(2))因子,梳理了电网平均CO_(2)排放因子历年发布时间轴和碳排因子数据现状。以天津地区某大型近零能耗办公建筑为例,开展电力碳排因子对于公共建筑碳等级评价的影响分析,其中电网CO_(2)基准线排放因子不适用于计算公共建筑碳排放量,可采用加权组合方式进行建筑光伏等可再生能源碳减量计算,采用全国电网碳排放因子和零碳建筑标准推荐因子均能较客观评价和区别公共建筑碳排放等级。对于零碳建筑、绿色建筑领域建筑碳排放量计算时关于电力碳排放因子的合理性选取具有一定的参考和借鉴意义。In response to the current situation where there are many types of carbon emission factors in the market and frequent updates.This paper provides a comprehensive analysis of the two main categories of grid carbon emission factors and summarizes the timeline of the release of the average grid carbon emission factor and the current status of carbon emission factor data.Taking a large nearly zero carbon office building in Tianjin as an example,this paper conducts an analysis of the impact of power carbon emission factor on the carbon rating of public buildings.The grid baseline emission factor is not applicable to the calculation of carbon emissions of public buildings,and the carbon reduction of renewable energy such as building photovoltaic can be calculated by a weighted combination method.The carbon emission level of public buildings can be objectively evaluated and distinguished by the national grid carbon emission factor and the zero carbon building standard recommendation factor.It has certain reference and significance for the rational selection of carbon emission factors for electricity when calculating the carbon emissions of buildings in the field of zero-carbon buildings and green buildings.
