摘　　要：确定教育建筑建材生产阶段碳排放计算方法,收集莆田市25栋教育建筑各类建筑材料的相关资料,并计算其重量及占比,确定砂、碎石、砌块、水泥、钢筋、粉煤灰、瓷砖、腻子粉、玻璃、石灰膏、铝作为碳排放计算的主要建筑材料,核算出这25栋教育建筑单位建筑面积碳排放量为255.70~398.03 kg CO_(2)e·m^(-2),钢筋、水泥、砌块、铝和瓷砖的碳排放量占总碳排放量的95.78%,是教育建筑在建材生产阶段节能减排的关键。应用箱线图法计算这5类主要建筑材料碳排放量的离散程度和变化阈值,结果表明钢筋、水泥和铝离散度较小,砌块和瓷砖的离散程度较大。结合以上研究成果,提出相应的减排策略,进一步推动教育建筑的节能减排。By defining the carbon emission calculation method of the material production stage of educational buildings,collecting relevant data on various building materials of 25 educational buildings in Putian City,and calculating their weight and proportion,it is determined that the sand,gravel,blocks,cement,steel bars,fly ash,ceramic tiles,putty powder,glass,lime paste,and aluminum are the main building materials for carbon emission calculation.Based on this,it is calculated that the carbon emission of the unit building area of educational buildings is between 255.70 and 398.03 kg CO_(2)e·m^(-2),and the carbon emission of steel bars,cement,blocks aluminum and ceramic tiles account for about 95.78%of the total carbon emissions,making them the key to energy conservation and emission reduction in the production stage of building materials for educational buildings.The application of box plot method to study the dispersion degree and change threshold of carbon emissions from main building materials shows that the dispersion degree of steel bars,cement,and aluminum is relatively small,while the dispersion degree of blocks and tiles is relatively large.Based on the above research results,the corresponding emission reduction strategies are proposed to further promote energy conservation and emission reduction in educational buildings.
