Based On The Method Of Life Cycle Assessment To Analyze The Dust Emission And Environmental Impact Of Residential Building With Frame Shear Structure

The scale of residential buildings has been expanding with the accelerated process of urbanization in China and the improvement of people’s demand level,the environmental problems have become increasingly prominent,and dust pollution has become the main environmental problems we face.Some researches show that the building discharges a large number of dust emission in the whole life cycle,which directly or indirectly increases the content of particulate matter in the atmosphere,so that aggravating the haze pollution.At present,the domestic researches on dust emission in buildings are mainly focused on the study of dust emission concentration and the quantitative analysis of construction dust,and there is very little research on the dust emission of residential buildings with frame shear structure.The life cycle assessment method is used to study and analyze the dust emission and environmental impact in whole life cycle of the residential building with frame shear structure.Based on the theory of life cycle assessment to divide the life cycle of residential construction with frame shear structure into four stages: namely,the material production stage,the construction stage,the operation and maintenance stage,the dismantling and waste disposal stage in this paper,constructing life cycle assessment model and using SimaPro software and Eco-indicator99 method to simulate and study the amount of dust emission and the environmental impact in the whole life cycle of residential building with frame shear structure in Zhengzhou,obtaining the simulated value of the dust emission and environmental impact in the life cycle of residential building,and giving the maximum stage and main influencing factors of the dust emission and environmental impact.Constructing the calculation model of the dust emissions to obtain the theoretical value of the dust emission.The theoretical and simulated value of the dust emission of residential building with frame shear structure are compared and analyzed,determined the maximum stage is the operation and maintenance phase,listing the corresponding solution measures to reduce the dust emission and the environment of residential building with frame shear structure,providing reference for the treatment of environmental pollution.
