建筑物物化阶段碳足迹快速计算模型研究

摘要

将物化阶段温室气体排放归结为建筑材料、施工机械、运输等三大碳足迹来源，以其构成建筑物物化阶段碳足迹，并基于BIM技术及《建筑工程消耗量定额》获取建筑的材料及机械工程量清单，运用碳足迹因子法计算三类碳足迹，形成建筑物物化阶段碳足迹计算快速模型。结合案例验证模型的正确性与可信性。%This paper divides the source of greenhouse gas into three sources:building material carbon footprint, construction machinery carbon footprint,and transportation carbon footprint,to form the carbon footprint of the buildings during its construction phase. Then,based on BIM technology and the Building Construction Consumption Quota to obtain the bill of material and machinery quantities,calculates the three kinds of carbon footprints with the method of carbon footprint factors,forms the carbon footprint fast accounting model. Finally, verifies the accuracy and credibility of the established model by combining the actual example.
