Nowadays, global warming is a big challenge for human beings; since the Kyoto Protocol became effective, greenhouse gas emissions have been an important environmental evaluation index in all industries. Construction is a big contributor to greenhouse gas emissions. The greenhouse gas emissions in the construction stage are mainly from the construction materials and the construction activities. The purpose of this paper is to quantitatively calculate the carbon dioxide emissions in the construction process, and provide a method of controlling the CO₂ emissions effectively by converting into cost. In this study, the authors selected the tunnel construction as the research object, and chose the primary greenhouse gas-CO₂ to estimate emissions. The authors did a research based on BIM (Building Information Modeling) technology, to calculate CO₂ emission during the construction process. It considered the CO₂ emissions from main materials and equipment. Finally, the authors used the recent carbon emission trading price to convert the CO₂ emission into cost, and did the economic analysis. The method proposed in this paper can effectively evaluate the CO₂ emissions in the construction process; it has a good reference significance for the selection of low-carbon emission materials in the design process, and it provides a case reference and direction for research of low-carbon equipment. By using the EU emissions trading system, the economic conversion of CO₂ emissions will provide an economic evaluation index for the CO₂ emissions of tunnel construction activities. Meanwhile, based on the method of this study, a BIM-based automated performance evaluation system could be developed.

基于BIM的性能评估系统开发过程中的CO2排放量计算方法

如今，全球变暖是人类面临的巨大挑战。自《京都议定书》生效以来，温室气体排放已成为所有行业中重要的环境评估指标。建筑是造成温室气体排放的重要因素。施工阶段的温室气体排放主要来自建筑材料和施工活动。本文的目的是定量计算施工过程中的二氧化碳排放量，并提供一种通过转化为成本有效控制CO ₂排放量的方法。在这项研究中，作者选择了隧道建设作为研究对象，并选择了主要的温室气体CO ₂估算排放量。作者进行了一项基于BIM（建筑信息模型）技术的研究，以计算建筑过程中的CO ₂排放量。它考虑了主要材料和设备的CO ₂排放。最后，作者使用最近的碳排放交易价格将CO ₂排放转换为成本，并进行了经济分析。本文提出的方法可以有效地评估CO ₂施工过程中的排放；它对设计过程中低碳排放材料的选择具有很好的参考意义，为低碳设备的研究提供了案例参考和指导。利用欧盟排放交易体系，CO的转化经济₂排放量将为CO经济评价指标₂排放隧道施工活动。同时，基于本研究的方法，可以开发基于BIM的自动化绩效评估系统。
