Study On Calculation Of Carbon Emissions Baseline Of Public Building Based On LCA

Global climate change is closely related to the excess carbon emissions of humanactivities. Energy and Resources consumption in the process of building construction, useand destruction of will bring enormous greenhouse gas emissions. So the building industryis one of the main sources of carbon emissions. At the same time, carbon reductionpotential of building industry is tremendous and cost low, as an important component ofthe international carbon trading market. Study on building carbon emissions baseline isimportant to reduce building carbon emissions and build carbon trading market. China’spublic building has high energy consumption and large carbon reduction space.Investigate measurement and econometric method of public buildings carbon emissions.In this paper, study baseline carbon emissions of public building based on the LCAtheory. Explore measurement and calculation methods of public buildings carbonemissions baseline. Divide life cycle of the public building into four stages, includingbuilding materials production, design and construction, use and maintenance, dismantledisposal. Analyze influencing factors, objectives, scope and list of measurement methodsof public buildings carbon emissions baseline. Explore measurement methods of publicbuilding carbon emissions baseline based on energy consumption and building materialsmeasurements. Study materials and energy consumption of each stage of public building.On the base of induction and analysis about energy, materials, labor, machinery and othercarbon emission factor, initially establish calculation formulas and specific methods ofbaseline of public buildings life cycle carbon emissions.Taking the Jiangan district in Wuhan city as an object and choosing14publicbuildings as samples for empirical study on the public building carbon emissions baseline.Through field investigation, measure carbon emissions of building samples. Publicbuilding carbon emissions baseline is68.65kg CO2/m2a year. Analysis of carbonemissions of public building suggests carbon emissions of use and maintenance influencepublic building carbon emissions most.
