摘要：In addition to consuming a large amount of energy resources, buildings inevitably destroy the ecological environment in the process of construction. Its main performance in water pollution, air pollution, construction waste and so on. Life Cycle Assessment (LCA) is an international standard method which systematically and quantitatively describes various resources, energy consumption and environmental emissions in product Life Cycle and evaluates their environmental impacts. The integration of building information model and LCA method will avoid repeated modeling and simplify data collection, and provide a certain technical framework for the development of BIM6D. In this paper, the BIM-LCA integration framework and the BIM6D model are established, and the environmental impact of a building in the quantitative analysis is used to guide the development of the BIM6D.
