摘要:随着双碳计划的提出，建筑行业作为能源消耗量与污染排放量的一大主体，与国家发展总目标之间的矛盾不断加剧，亟待新兴技术改革。BIM技术所具有的信息携带量大、交互效率性高等特点可应用于解决这一问题。但以往的研究普遍过程相对繁琐，容易丢失大量的信息，所得结果不够精确。本文旨在使用C#编程语言，通过Revit API接口对Revit软件二次开发，研究出一款高效的物化阶段建筑碳排放计量软件。通过建立建筑材料与施工机械信息编码库，结合已有碳排放因子数据库，对建筑物化阶段所产生的碳排放量展开深入分析。结果表明，物化阶段中建材生产阶段所产生的碳排放量最高，施工阶段几乎可以忽略不计。研发的建筑碳排放计量软件操作简单且功能较为完善，是对当下国家绿色发展方向的积极探索。

Abstract: In recent years, carbon peaking and carbon neutrality goals have been big concerns. However, as a major player in energy consumption and pollution emissions, the construction industry's development of traditional ways is contradictory to the overall national development goals. Therefore, technology reform in the construction industry is heavily required. The BIM technology has the characteristics of large information carrying capacity and high interaction efficiency, which can be fully applied to solve this problem. However, previous researches have generally been relatively cumbersome and prone to losing a large amount of information, hence the results of previous researches are inaccurate. This paper aims to develop an efficient carbon emission measurement software through the secondary development of Revit software using the C # programming language and the Revit API interface. By establishing a coding library for building materials and construction machinery information and using existing carbon emission factor databases, in-depth analysis is conducted on the carbon emissions generated during the construction phase. The results indicate that the carbon emissions generated during the production stage of building materials are the highest in the physical and chemical stage, and can be almost negligible during the construction stage. The software developed in this paper is easy to operate and has relatively complete functions, which is a positive exploration of China's Green Development.
