Measurement Of Carbon Emissions Throughout The Life Cycle Of Integrated Prefabricated Concrete Houses And Emission Reduction Strategies

For a long time,the development of the construction industry has had serious negative effects,not only due to the serious waste of resources and energy in production operations,but also prone to serious environmental pollution.A large amount of research has confirmed that construction activities consume about 40% of natural resources and energy,with pollution emissions accounting for 40% of total human emissions,and greenhouse gas emissions from construction throughout the year accounting for 1/4 of total emissions.It is evident that it is urgent to persist in conducting necessary carbon emission research on the construction industry and strengthen the promotion of low-carbon emission reduction in construction.In people’s consensus,continuously optimizing production and lifestyle,and achieving more transformative innovative actions will better achieve energy conservation and emission reduction goals,which is also applicable in the construction industry.However,in the current situation,there is still a need for in-depth exploration of energy conservation and emission reduction for prefabricated concrete residential buildings.It is of great significance to actively grasp carbon emission standards and requirements,and deeply understand the carbon emission patterns throughout the entire life cycle of prefabricated concrete residential buildings.This article adopts multiple methods such as literature research,comparative research,and the combination of qualitative and quantitative methods to complete a hierarchical research from theory to practice.The introduction section first introduces the research background,explains the significance of the research,introduces the research ideas and methods used in the entire text,and explains the key points,difficulties,and innovative points of the research.It summarizes and analyzes the current research situation from both domestic and foreign perspectives.The second chapter first explains the basic concepts of prefabricated concrete residential buildings,carbon emissions and carbon emission factors,carbon emissions of prefabricated building,and the whole life cycle,and takes the ecological footprint theory and the whole life cycle assessment theory as the basic supporting theory.The third chapter is the calculation and analysis of carbon emissions of prefabricated concrete residential buildings,which explains the calculation principles,calculation methods and calculation formulas of carbon emissions successively,and explains the influencing factors of carbon emissions of prefabricated building from four aspects of government policies,social economy,market environment and building energy consumption.And a comparative study and analysis were conducted on the carbon emissions of prefabricated concrete residential buildings and cast-in-place buildings in three stages of production,transportation,and construction.Chapter 4 is the calculation of carbon emissions from prefabricated concrete residential buildings throughout their entire life cycle.Specific engineering cases are selected in the article,and factors are selected and quantified for carbon emissions during preparation,construction,use,demolition,and recycling stages.Finally,emission reduction strategies for prefabricated concrete residential buildings throughout their entire lifecycle were proposed.The article mainly proposes emission reduction strategies from aspects such as building materials,design,usage,and government support.This article combines theoretical research and practical case studies to study the carbon emissions of integrated prefabricated concrete residential buildings throughout their entire life cycle.It points out effective calculation methods,which not only provide technical support for achieving low-carbon contribution throughout the entire life cycle of integrated prefabricated concrete residential buildings,but also provide necessary theoretical basis and practical guidance for the healthy and green development of other low-carbon buildings in China.
