Research On Environmental Impact Assessment System Of Green Building Materials

With the vigorous promotion of ecological civilization construction in China and the continuous improvement of human requirements for green and pollution-free construction materials industry,the green construction materials industry has become an important pillar of our national economy.A large number of building materials have emerged as the times require.Some building materials produce a large number of toxic and harmful substances during their life cycle,causing serious environmental pollution.Therefore,how to design a set of environmental impact assessment index system for green building materials has become the focus of current research.Firstly,in the research of green building materials methods,this paper takes concrete and green concrete and other building materials products as research objects,and establishes an AHP-comprehensive fuzzy evaluation model based on LCA-LCC based on life cycle assessment(LCA),life cycle cost analysis(LCC),and fuzzy comprehensive evaluation methods.After a series of investigations,four first level indicators,15 second level indicators,and 40 third level indicators were determined.Based on this,the weight scores of each indicator were calculated,and the final calculated scores of concrete and green concrete were 65.3 and 93.7,respectively.The green grade score of concrete was medium,and the green grade score of green concrete was excellent.At the same time,in the process of building a fuzzy evaluation model for green building materials,it provides a foundation for the establishment of a green building materials information evaluation system.Secondly,based on the evaluation standards for green building materials,a series of analysis is conducted on the green building materials information evaluation system,including process analysis,business analysis,and so on.On this basis,the extraction of entity classes and functional modeling were determined,and the refinement of the green building materials information evaluation system was completed.Finally,the development of the green building materials information evaluation system is completed,and the evaluation system simulation is conducted.The results show that the functions and performance of green concrete meet the requirements of green building materials evaluation.The design and development of a green building materials information evaluation system helps to achieve rapid evaluation of green building materials,thereby accurately and quickly understanding information resources,and providing support for high-level decision-making.
