Research On Green Building Evaluation Based On BIM Technology

In today's world,energy and resources are scarce,and ecological and environmental pollution is becoming more serious.In order to solve the situation of high energy consumption and high pollution,the development of green building concept has become particularly important.The introduction of the BIM(Building Information Modeling)technology in green buildings can further optimize the energy-saving design of buildings and achieve the development goals of green buildings.At present,China's green building development is still in its infancy.There are a lot of repetitive work and inefficiency in many aspects of green building evaluation.Therefore,Building Information Modeling(BIM)can be used as a carrier for information processing and interaction.Efficiency for environmental analysis of green buildings.This paper firstly reviews the development status and progress of BIM and green buildings at home and abroad,introduces the theory and application of BIM and green buildings,and summarizes the connotation and characteristics of BIM and green buildings.Secondly,by introducing the green building evaluation system at home and abroad,and comparing the new and old versions of green building evaluation standards in China,the development trend of the combination of BIM and green building is also realized,which also provides an evaluation basis for the subsequent analysis of architectural projects.Thirdly,the general way of building modeling is introduced.Grouping according to the profession,the building is decomposed into multiple unit parts,and finally the collision analysis is carried out.This article highlights the advantages of BIM technology collaborative work and optimizes the process of the architectural design phase.Finally,this paper uses BIM technology to model an actual building project,and introduces the BIM model into the building energy analysis software to analyze the outdoor wind environment,acoustic environment,natural ventilation and daylighting of the project,thus explaining the green building.Reliability and feasibility combined with BIM technology.
