以高校建筑碳中和为目标的碳收支核算研究

Research on carbon budget accountingwith the goal of carbon neutrality of university buildings

碳收支核算是实现校园建筑碳中和目标的前提和基础。以南京工程学院主校区建筑为例,采用排放系数法对校园建筑碳收支进行核算。根据高校建筑能源消耗特点,将校园碳收支结构划分为建筑碳排和生活碳排。研究结果显示,近5年来,该校校园年均碳排放总量为34365 t,人均碳排放量为1.18 t/a,且近年来碳排放量变化不明显。电力碳排放是建筑碳排放的主要贡献因素。与国内外校园碳排放量进行对比后发现,该校校园整体碳排放处于较低水平。最后提出了实现该校园建筑碳中和的路径,包括绿色建筑发展、建筑光伏发电以及碳交易市场等三种方式。

Carbon accounting is the prerequisite and foundation for achieving carbon neutrality goals in campus buildings.Taking the main campus of Nanjing Engineering Institute as an example,this paper employs the emission coefficient method to calculate the carbon balance of campus buildings.According to the characteristics of energy consumption in university buildings,the carbon balance structure on campus is divided into building emissions and lifestyle emissions.The research results show that over the past five years,the annual carbon emissions of the campus have averaged 34365 tons,with a per capita carbon emission of 1.18 tons per year,and there has been little change in recent years.Electricity emissions are the main contributing factor to building emissions.After comparing with domestic and international campus carbon emissions,it was found that the overall carbon emissions of the campus are at a relatively low level.The paper proposes pathways to achieve carbon neutrality in campus buildings,including the development of green buildings,building photovoltaic power generation,and participation in the carbon trading market.
