摘　　要：为分析建筑物全生命周期碳排放,以达到节能减排的目的,以某教学楼建筑为研究对象,结合生命周期过程分析法及投入产出分析法,对该建筑的碳排放进行测算,得出以下结论:混凝土、钢材、砌体材料是影响建筑物碳排放的主要材料,减少其用量,是控制教学楼碳排放的有效途径。减少运输阶段对汽油、柴油等不可再生资源的消耗,是减少建筑碳排放重点,可通过降低对公路货运的依赖,使用铁路等电气化程度较高的运输方式,或降低运输距离,达到减少碳排放的目的。In order to analyze the life cycle carbon emissions of buildings and achieve the purpose of energy saving and emission reduction,this study took a teaching building as the research object,combined the life cycle process analysis and input-output analysis,calculated the carbon emissions of the building,and reached the following conclusions:concrete,steel and masonry materials are the main materials that affect the carbon emission of buildings.Reducing their consumption is an effective way to control the carbon emission of teaching buildings.Reducing the consumption of non-renewable resources such as gasoline and diesel in the transport stage is the focus of reducing building carbon emissions,which can be achieved by reducing the dependence on road freight,using more electrified modes of transport such as railways,or reducing the transport distance.
