The Study Of Small Buildings Carbon Emission In Plateau With Extreme Climate

With the development of human industrial activities have become increasingly frequent, the energy consumption is rising, causing global warming, which leads to the greenhouse effect.The excessive emissions of carbor dioxide is the main cause.Constuction industry is a big energy consumption.The quantity of energy used by construction activities has accounted for40%of human energy using,which cause a huge number of carbon emissions. Construction industy is one of the most serious factors of the air pollution.In order to control the carbon-emission of the construction activities,chose an air force station as the object,according to field investigation,detection and analysis,quantitative calculation and comprehensive evaluation,determine the environmental characteristics and the waste emissions,calculate the carbon-emission of the main building(the solar bathroom) and evaluate the result. Erect the evaluation system of low carbon-funtion of the whole station.Through field investigation,conclude the average temperature in winter and summer is-17.48℃and8.04℃, the average outdoor humidity in winter and summer is35.62%and81.19%.The average daily water consumption is21.17L per person,the average daily sewage emissions is22.24L per person and the solid waste is1.18kg per person per day.Estimate the carbon-emission of every stage of the whole life cycle of the solar bathroom which are:the production and processing stage of building materials,the constucion stage,the using stage and the abandon-demolition stage. Find out that the percentages of carbon emissions in every stage are76.35%,11.24%,9.89%and2.52%.Because of using the solar energy in using stage,the carbon emissions in the cycle life of the buildings has reduced.Emission reduction efficiency is5.42%. Through the investigation and using condition,evaluate the building by the carbon emission,deem that the building is reasonable and feasible and can promote in the southwest area with the similar extreme climate.Extend the carbon emission calculation to the whole station,integrate the station survey,use function and the status of staff, erect the evaluation system of low carbon-funtion.Evaluate the station and the result is good. The study can provide guidance for the new station construction in the future in the similarly extreme climate area which can make the function of the building and carbon-emission balance and reduce the influence to the environment.
