Environmental Benefits of Green Buildings with BIM Technology

Abstract

Abstract Under accelerated urbanisation and rapid social and economic development, environmental pollution has become an important content of the construction industry. Therefore, the environmental benefit analysis of green buildings is of great significance to the effective use of energy and resources and to achieve the goal of protecting resources, reducing pollution and improving the ecological environment. The results show that the measured results of incremental environmental costs of the office building in Taiyuan City in land saving, energy saving, water saving, material saving, indoor environmental quality and operation management are decreased by 13.56 %, 11.02 %, 25.17 %, 14.43 %, and 15.25 %, respectively; incremental environmental benefits in land saving, energy saving, water saving, material saving, indoor environmental quality and operation management are increased by 23.15 %, 10.37 %, 19.30 %, 18.25 %, and 22.53 %, respectively. Those suggest that the BIM technology applied to the complete life cycle cost analysis of green buildings can test, measure and guide all the steps of building design, construction and maintenance and largely meet the criteria of resource-saving and energy-saving. The results of this paper provide a reference for further research on the environmental benefit analysis of green buildings based on BIM technology.
