Typical Residential Building Life Cycle Particulate Matter Emission Calculation Model And Prevention Study

As the social public attention to the building energy saving and emission reduction increasingly, and the hazy weather is becoming more and more serious in recent years, it is an emergent problem to be solved that to realize the construction with scientific measurement of building particulate matter emission. Currently, building particulate emission research is mainly on the qualitative level, but the quantitative research is less.First of all, this article is based on the basic theory of Life Cycle Assessment (LCA) and its framework, dividing the building life cycle into five stages including material production, material transportation, construction and installation, operation and maintenance, dismantle processing phase. Construction project referring to the pollution source is divided into the source of energy consumption and secondary dust source.Secondly, through consulting,collecting and summarizing the main sources of domestic and overseas pollution emission factor and the method of factor calculation to establish the related product particulate matter emission data list and figure out the whole life cycle of a typical residential building mathematical calculation model of particulate emissions which combined with the feature of the particulate emissions.Thirdly, select and analysis a typical residential building case, quantitative in different stages of the whole life cycle of construction projects particulate matter emissions. The results show that the whole life cycle of a typical residential building in the operation and maintenance phase of the total suspended particulate matter emissions accounted for 44.49%, next is the material production stage of 39.45%, and the material transportation, construction, installation and dismantle processing occupy a smaller proportion which is 6.51%,0.52% and 9.03% respectively.Finally, relying on the measurement data, this article analyses the characteristics of different stages of particulate emissions detailedly and also gives a suggestion for particulate emission control measures. And on the basis of this, it puts forward the prevention and control of particulate matter in whole life cycle of evaluation system, using fuzzy comprehensive evaluation method of AHP simulated particle control goal of the evaluation process, which proved this method that has good feasibility.
