Research On Community Household Carbon Emissions In Low-carbon Community Planning

Carbon emission in community is the basic unit of urban carbon emission system.Therefore,it is very significant to conduct research on carbon emission in community,which is crucial for the low-carbon city construction.Family is the basic component of the community.As the ultimate beneficiaries,families are the core of the energy consumption and the most important source of carbon emissions.Therefore,household energy consumption and household carbon emissions can’t be ignored.This paper systematically summarizes the connotation,characteristics and evaluation system of community carbon emissions and community household carbon emissions.In addition,the constituent elements of community carbon emissions are also clarified in this paper.Household carbon emissions can be divided into two types which are living carbon emissions and transportation carbon emissions.Finally,the relationship between community carbon emissions and household carbon emissions is obtained in this paper.In order to quantitatively analyze the issues related to carbon emissions of community households,the data collection methods and calculation methods for carbon emissions of community households at home and abroad are explored based on theoretical research.And household and traffic carbon emissions calculation models are established with the method of the carbon emission coefficient.Through the actual energy-related data in China,the carbon emission coefficient of each category can be calculated.A community household carbon emissions calculation model will be established which is suitable for Chinese community conditions and energy consumption.To further analyze the factors that affect the carbon emissions of the community,the surveys of six communities(three of them are low-carbon communities)in Tianjin are conducted and the basic data of the carbon emission is collected.In addition,the household carbon emission calculation model is introduced so as to obtain the corresponding household carbon emission data.Based on the SPSS data analysis platform,the correlation degree between the family characteristics and household carbon emission is quantitatively analyzed and the multiple regression model of Family Characteristic Influencing Factor-Family Comprehensive Carbon Emission Index is constructed.In the aspect of spatial shape,through quantifying the density index and diversity index of community space form,they are compared with carbon emissions respectively to comprehensively analyze the correlation degree between community space patterns and the family’s internal carbon emissions;In terms of transportation and accessibility,the impacts of different modes of travel,accessibility of public transport,accessibility of public service facilities on household travel carbon emissions are studied;in the aspect of energy efficiency,the relationship between the heat indicators,building energy consumption per unit area,renewable energy utilization,and actual household carbon emissions are analyzed.Furthermore,this paper analyzes the interaction among factors which are family characteristics,spatial shape,family transportation and building energy efficiency and gives the scientific feasibility suggestion for community emission reduction.Finally,on the basis of the above research,the specific feasible low-carbon community planning strategy is put forward from the perspective of reducing the carbon emissions of the family...
