Abstract

According to the idea of life cycle assessment, taking the floor of a building as the object, this paper uses BIM technology and tools to build a multi-dimensional information model of the construction project, further defines the relationship between BIM model elements and building materials, and quantifies the environmental impact of building materials. Through the classification, characterization, standardization and weighted evaluation of the results generated by the BIM-LCA function module (Tally), the impact potential of different environmental impact types in each stage and the environmental impact size of the same environmental impact type in different stages are obtained. The analytic hierarchy process is used to establish the environmental impact assessment index database of construction projects in order to measure the feasibility of construction projects.
