Application Research of BIM in Environment Assessment of Full Life Cycle for Construction Projects

摘要

The energy consumption and pollutant emission of construction engineering bring great impact on environment, so we propose a scheme based on the full life cycle in this article. It adopts BIM technology and relative tools to establish multi-dimensional information mode of construction projects and further define the relation between BIM mode elements and building materials, by quantifying the environmental effect of building material and establishing assessment index library of project environmental impact. Then the environmental decision method in BIM-LCA, AHP is introduced by detailed procedures and decision conclusions, and specific cases are also provided. The study results show that in the assessment of full life cycle, BIM model can provide most data needed for LCA. Corresponding measures can be taken according to the environmental impact assessment results produced by different phrases, which shows active roles for the decision assessment of construction project and provides valuable decision making for high-performance architectural design.
