Study On The Application Of BIM In Green Building Design

Nowadays,energy consumption in the construction industry accounts for a large proportion of the social total energy consumption.In order to realize sustainable development and energy saving,the conception of green building comes into being.Green building uses technology which contains sustainable development concept throughout its lifecycle of design,construction then operation,to save land,water,materials and to serve people with healthy,applicable,efficient use space in harmony with nature.In today’s information age,it is inevitable to use computer to help people work efficiently.And BIM(building information modeling)is a kind of technical means,aids to design,construct and operate construction industry with three-dimensional information.This paper proposes application methods of BIM in green building,solution of the problems occur as well as the workflow when green building applies in traditional design on the basis of the fundamental theory researches on features and related standards of BIM together with the principles,purposes,and strategies of green building design,according to the advantages and characteristics of visual design,collaborative design,information interoperability,performance simulation.etc.In the early stage of design,this study uses BIM to conduct site climate analysis,site modeling,site elevation,slope,drainage and other analyses with the final design of the site which includes the formation and the road design.In the project design stage,making use of BIM parameters and visualization characteristic,combining sunshine,ventilation and other performance simulation,this study conducts the passive design for the building body and the total layout.Then,on the basis of simple BIM model,the best option is picked out after performance analyses and comparison.In the preliminary design stage,BIM parameters is used in collaborating with each expertise to deepen the design of the program,what’s more,in order to meet the requirements of the green building evaluation standards,the study optimizes the design via varieties of performance simulations.In the construction drawing design stage,BIM visualization applies in pipeline arrangement and pipeline collision check,preparing for the green construction.Finally,practical research is carried out combined with actual cases,which aims to test and demonstrate the feasibility of BIM application in green building design.
