摘要:管道碳排放自动计算系统对于管道设计阶段的碳排放预测和碳排放减少路径的研究具有重要意义。本文基于碳中和目标的背景，以《建筑碳排放计算标准》为计算依据，首先总结归纳出主要涉及的管道材料及其碳排放因子，根据BIM建模规范，指定相应的计算标准；其次基于Revit模型中管道的计算量、规格、材质等数据，采用碳排放因子方法，并使用C#+RevitApi对Revit进行二次开发实现了自动计算管道碳排放量的功能，该系统能够帮助设计师快速获取较为准确的管道碳排放量，在设计过程中优化了碳排放，证明了该系统具有广泛的应用前景和市场价值。

Abstract: The automatic calculation system for pipeline carbon emissions is of great significance for predicting carbon emissions and researching pathways to reduce carbon emissions during the pipeline design process. Aiming at carbon neutrality goals and meeting up with "Building Carbon Emission Calculation Standard," the main pipeline materials and their carbon emission factors are summarized and compiled in this paper. According to the BIM modeling specifications, corresponding calculation standards are specified. Then, based on the data of pipe quantity, specifications, materials, etc., in the Revit model, the carbon emission factor method is adopted, and the functionality of automatically calculating pipeline carbon emissions is implemented through secondary development by using C# + RevitAPI. This system can help designers quickly obtain relatively accurate estimates of pipeline carbon emissions and optimize carbon emissions during the design process. Therefore, the system has broad application prospect and market value.
