Research On Carbon Emission Accounting Of Construction Period Of Frame Structure Construction Project

In the process of assessing construction industry carbon emissions by using whole life cycle,the calculation of greenhouse gas emissions is crucial.Indeed,the measures aimed at solving the greenhouse gas emissions are an indispensable development strategy for low-carbon development.The paper first clarifies the whole life cycle theory of construction projects.Then,based on the construction unit and by means of construction project classification and integrated auxiliary,a carbon emission inventory for construction projects is established.Finally,this paper insists on the construction enterprise as the center,determines the norm and target of greenhouse gas emission during the construction period,and extracts the data in the discharge operation.Based on these,the gas emission calculation framework is established to provide a useful basis for the analysis of carbon emission during the construction period.Based on the gas emission calculation framework during the construction period,the paper selects eight frame structure constructions in Nan Ping to account carbon emission.According to the construction process,it detailedly calculates the discharge of resource consumption and its composition in the process of scaffolding engineering,earthwork engineering,main structure reinforcement engineering,basic engineering,main structure masonry engineering,main structure concrete project,vertical transportation engineering,and main body structure template engineering.And it also describes and analyzes the carbon emission status of the project.This paper not only establishes the calculation framework of carbon emission during construction period of frame structure construction,and makes quantitative analysis on the carbon emission of construction enterprise projects,but also analyzes the greening emission reduction measures of banyan and mango trees by the grey relational analysis method and entropy method-fuzzy comprehensive evaluation method.The ratio of emission reduction measures of banyan is about 0.77 percent,and the cost increase is about 0.19 percent.Through the grey relational analysis method,emission reduction measures of banyan are more feasible.The ratio of emission reduction measures of mango trees is about 0.82 percent,and the cost increase is about 0.19 percent.Through entropy method-fuzzy comprehensive evaluation method,the reduction measures of mango trees are more feasible.
