建筑物物化阶段碳足迹快速评价研究

Study on rapid evaluation of carbon footprint of building during construction period

为快速计算建筑物物化阶段碳足迹,通过对施工现场进行实际调研,更新了运输碳足迹因子数据库,并据此提出运输碳足迹计算方法,建立了物化阶段碳足迹快速评价模型。将建筑信息模型(BIM)技术与计算机技术应用到碳足迹评价中,明确碳足迹计算数据来源,使碳足迹评价系统化、规范化,开发并建立了"建筑施工碳足迹核算系统"。结合具体案例进行系统应用分析,应用"建筑施工碳足迹核算系统"对大连某多层框架结构建筑进行碳足迹计算,简要分析了计算结果的精确性与案例碳足迹水平,得出该建筑物物化阶段碳足迹水平为443.44 kg CO2eq/m2。运输碳足迹计算方法的研究与"建筑施工碳足迹核算系统"的开发将为建筑业碳足迹研究提供参考。

In order to calculate carbon footprint of building during construction stage quickly,we updated the database of transport carbon footprint factors,created a new calculation method for transport carbon footprint and established a fast evaluation model based on practical investigation. By using BIM and computer technology,we established ＂ building construction carbon footprint calculation system＂,which made the data source clear and more systematical and standardized calculation and assessment of carbon footprint. Finally,we used the established system to calculate the carbon footprint of a multi-storey frame building in Dalian. The accuracy of calculation results and carbon footprint level of the case had been studied. Results showed that the carbon footprint level of the case was 443. 44 kg CO2 eq / m2. The calculation method of transport carbon footprint and the established system could provide a reference for the research of carbon footprint in building industry.
