Prefabrication has gained its popularity in countries including China due to its various advantages such as quality control, waste reduction, onsite and offsite parallel coordination, and so on. It has also been recognized as a key strategy to reduce construction-induced carbon emissions. However, there is limited research to examine carbon emission reduction in prefabrication by using the advanced technological artefacts, e.g., building information modeling (BIM), emerging from the technology sphere. As a digital representation of a facility, BIM provides a cyber platform based on which many assessment and simulation works can be performed without having to construct the physical facility. This paper aims to develop a BIM-based approach to measuring carbon emission reduction during the materialization stage of a prefabricated building project. Findings from the study indicate that BIM is an efficient and effective method for measuring carbon emissions from the construction of new buildings and that prefabrication reduces carbon emissions when compared with conventional construction methods. The research contributes to the body of knowledge relating to the reduction of carbon emissions through prefabrication. This is pertinent to contractors, homebuyers and governments who are constantly seeking ways to achieve a circular economy.
预制化在中国等国家因其质量控制、减少浪费、现场和场外并行协调等诸多优势而广受欢迎。它也被认为是减少建筑碳排放的关键策略。然而，利用建筑信息模型（BIM）等技术领域先进的技术手段来研究预制化减排的研究还很有限。BIM 作为设施的数字表示，提供了一个基于网络的平台，在这个平台上，可以在不建造物理设施的情况下进行许多评估和模拟工作。本文旨在开发一种基于 BIM 的方法，用于测量预制建筑项目材料化阶段的碳排放减少量。研究结果表明，BIM 是一种测量新建筑施工过程中碳排放的有效方法，与传统施工方法相比，预制化可以减少碳排放。本研究为通过预制化减少碳排放的知识体系做出了贡献。这对于承包商、购房者和政府来说都是相关的，他们一直在寻求实现循环经济的方法。
