Deduction and Demonstration of Building Construction Carbon Emission Model Based on BIM Model

This study focuses on building construction carbon emission model based on BIM model, specific model deduction and practical application. In this study, the current construction life cycle carbon emission composition is mainly analyzed, and then the main calculation method of the construction life cycle carbon emission of the building is proposed. Based on this calculation and deduction process, a BIM-based carbon emission measurement model is established. In view of the corresponding calculation steps of carbon emission measurement in the application process of this model, the results of this study show that the BIM based carbon emission model of building construction can effectively complete the measurement of carbon emission coefficient. However, it will be affected by the architectural environment to a certain extent. Therefore, in further application, the variable and adaptability of the experimental results should be considered based on the differences between other regions.
