The Framework For Integrated BIM-lCA And Case Studies

Operational energy consumption of buildings accounts for a maijor part of the totalenergy consumption in China. It is also true that in building life cycle process, theenergy consumption and environmental impacts of every stage (including buildingmaterial production, transportation, construction, maintenance, refurbishment, andend of life) are huge. A number of countries and districts have discussed the buildinglife cycle environmental and economical impacts to find a sustainable way. However,those problems are serious in China, and there is a need to investigate it.The major objective of this study is to investigate the Life Cycle Analysis approachand BIM theory to discover their combination and create an integrated BIM-LCAframework. This framework is the basis for evaluating the life cycle carbon emissions,energy consumption and costs of buildings.Througu literature review and comperative study, the evaluation system and analyticaltools concerning integrated LCA and LCC methods are examined. The aim is toestablish simplified and comprehensive framework for building life cycle analysis,analyze the process of evaluating a building’s life cycle environmental andeconomical impacts.The methology was implemented and verified through two caes studies, namely ahigh-rise residential building and a retrofitting project of a campus building. Thelimits and persepectives are dissicussed accordingly.
