Research On The Life-cycle Carbon Emission Measurement Model Of Rural Residential Buildings In Liaoning Province

Studies have shown that a large number of man-made emissions of carbon dioxide are the main cause of global climate change.Climate change is related to the common safety of mankind and is a focus of global attention.The energy consumption of the construction industry has always been at the forefront of all industries.In the 1990s,China The growth rate of carbon dioxide emissions is 4%,of which the construction industry accounts for the largest proportion,accounting for about 30%.China’s building energy consumption accounts for the largest proportion of residential energy consumption,and rural residential energy consumption accounts for a relatively large proportion according to research.Therefore,rural Research on residential carbon emissions throughout the life cycle will be the main link in the implementation of China’s emission reduction plan.Therefore,this project is based on rural residential houses in Liaoning Province to build a carbon emission measurement model for the entire life cycle of rural residential houses in Liaoning Province,which will provide a comprehensive assessment of rural residential carbon emissions.Statistics provide quantitative measurement tools,which can improve the calculation accuracy of rural residential carbon emissions,provide a carbon source database for statistics of rural residential carbon emissions in Liaoning Province,and provide a basis for national statistics on rural residential carbon emissions,and for the subsequent development of rural residential Provide data support for research on carbon emission reduction measures,and provide reference data for low-carbon standards for the development of low-carbon buildings.In China,there are few studies on rural housing in the relevant research on the carbon emissions of residential buildings throughout the life cycle,and the research stage is still very preliminary.Therefore,in the research of this thesis,the research background of this thesis is introduced in the first chapter because Global warming China’s commitment to emission reduction requires effective emission reduction measures and tools to measure carbon emissions.Chapter 2 discusses the basic theories and methods of building carbon emission measurement.The theoretical choice is based on the life cycle analysis(LCA).Based on the concept and theoretical framework,the five stages of the whole life cycle are split,and the carbon sources of the five stages related to rural houses are summarized in a table according to the characteristics of rural houses,and a survey questionnaire is made to investigate the five rural houses on the spot.The carbon sources and influencing factors of carbon emissions in the life stage are obtained.In Chapter 3,based on the survey data,we summarize the life cycle carbon sources of rural houses,including rural residential layout and building characteristics,rural residential construction characteristics,rural residential energy Structure,etc.In Chapter 4,based on the original existing general model,the carbon emissions of rural houses are measured,and the regression analysis method is used to analyze the linear relationship between the model variables and the number of rural residential spaces,and to simplify the basic model between the variables To construct a universally applicable model for measuring carbon emissions from rural residential buildings.In Chapter 5,aiming at Sa Niugou Village,West Wujiazi Township,an actual rural village in Liaoning Province,the carbon emission measurement model summarized in Chapter 4 is used to calculate the carbon emissions of the entire village,and the original existing measurement model is used at the same time.Calculate,and finally analyze the data results calculated by the two measurement models.In Chapter 6,a data simulation of a single house was carried out to analyze the impact of changes in the material selection and structure of the house on carbon emissions.After summarizing the calculation results in Chapter 5,this chapter proposes the emission reduction strategy for rural residential buildings in Liaoning Province The optimization direction mainly optimizes the maintenance structure from the optimization of the body shape coefficient,the addition of insulation layers and the improvement of wall technology,and the optimization of the building layout form from the spatial layout direction and the addition of sunshine rooms,and proposes the emission reduction optimization principle of rural residences from the perspective of the building itself.To achieve the goal of reducing emissions.Finally,Chapter 7 summarizes the research process and research conclusions of this paper,and proposes that this paper still has shortcomings,and further research is needed in future research directions.Finally,a universal Liaoning Province rural residential carbon emission measurement model is obtained,which can quickly calculate all carbon emissions in a certain village,and summarize the specific strategies for the design and construction of rural residential buildings in the region based on the carbon emissions.
