Research On Carbon Emission Calculation And Emission Reduction Strategy Of Residential Buildings In The Whole Life Cycle

With the continuous construction and development of human beings on the earth,the available resources on the earth are more and more limited,people are facing the crisis of energy shortage,at the same time,global warming has brought adverse effects on human survival.The construction industry comes from itself,consumes a large amount of energy resources,generates a lot of garbage in the construction,and has a large construction emission.Therefore,the low-carbon emission reduction of the construction industry has been paid more and more attention.Because of its advantages in low energy consumption and low pollution,prefabricated buildings have been widely used in the current residential research and practice.With the continuous advancement of prefabricated buildings,higher requirements have been put forward for residential construction cycle,residential demand,low-carbon emission reduction and other aspects.The first chapter of this paper is the introduction.It systematically summarizes the current characteristics of the full life cycle of residential buildings and relevant studies on building carbon emissions,so as to clarify the purpose and significance of this paper.The second chapter determines the theoretical basis of the research.Based on the theory of the full life cycle of buildings,it determines that the life cycle of residential buildings is divided into four stages,namely,the stage of building materials preparation,the stage of building construction,the stage of building use and maintenance,and the stage of building demolition and recovery.At the same time,the measurement method of carbon emission of buildings with full life cycle is determined,and relevant carbon emission factors are collected to prepare for carbon emission analysis and calculation of project examples.Chapter III,from the perspective of the full life cycle,sorts out the carbon emission sources and characteristics of the four stages of Building 9 of Lishui New Town Project,calculates the carbon emission of each stage in detail,and summarizes the carbon emission characteristics of the full life cycle.Chapter iv,from the perspective of the full life cycle,takes the project as an example to analyze the impact of material selection,construction method,exterior wall insulation design,building material recovery and other aspects on building carbon emissions.Through carbon emission quantitative analysis,it shows that the optimization of the above methods can achieve the goal of reducing residential carbon emissions.Chapter Five summarizes the strategies of building emission reduction from each stage of the whole life cycle of residential buildings.Based on prefabricated high-rise residence as the research object,this paper summarizes the characteristics in each stage of whole life cycle,from building materials to prepare and calculate the stages in the whole life cycle of building the recycling of carbon emissions,analyzed the influence of the design elements of building carbon emissions,prefabricated high-rise building design low carbon reduction strategy is put forward,at the same time to prefabricated building energy conservation and emissions reduction to provide basic data for later.Lishui,this paper takes shenyang metro project residence as the research object,summarizes its characteristics in each stage of whole life cycle,from building materials to recycle and calculate the whole life cycle of carbon emissions,at all stages of the lifecycle stages analysis factors of influence on construction of carbon emissions,residential construction low carbon reduction strategy is put forward,at the same time,housing construction energy conservation and emissions reduction to provide basic data for later.
