Research On Low-Carbon Campus Planning Of Shenyang Jianzhu University Based On "Source And Sink" Theory

With the rapid development of science and technology and modern economy,people’s consumption of energy is increasing day by day,the temperature is rising and the climate is getting worse,which has had a huge impact on the world.Colleges and universities are an important space carrier for realizing low-carbon development and an important ecological unit for addressing global climate change.At present,the research on low-carbon campus planning at home and abroad focuses on the formulation of low-carbon regulation policies and relevant implementation plans,but there is a lack of quantitative analysis on the flow and operation of material and energy elements in the campus ecological complex system.Therefore,this thesis conducts low-carbon campus planning research based on existing low-carbon related theories.Based on the theory of "source and sink",this paper takes Shenyang Jianzhu University as the research object,uses the research methods of theoretical research,data collection,qualitative and quantitative analysis to sort out the concept,development history and application of "source and sink" theory in low-carbon campus,and defines and analyzes the concepts related to low-carbon campus.Classifies carbon sources and sinks in campus,summarizes and sorts the accounting methods of carbon emission and carbon sequestration,and puts forward evaluation methods.Based on data statistics and quantitative estimation of codes and standards,shenyang Jianzhu University was selected as a practical case to evaluate the carbon emissions during campus operation.Carbon emissions from carbon sources are mainly divided into three aspects: architecture,life and transportation.Carbon sequestration mainly considers green space system and building concrete in campus.Finally,the comparative coefficient of net carbon emissions,carbon balance coefficient and per capita carbon emissions of the campus was analyzed to judge the degree of low-carbon campus,and the main factors affecting carbon emissions were summarized.On the basis of summarizing the main influencing factors of campus carbon emission,the planning strategy is proposed from four aspects of fixed carbon source,mobile carbon source,process carbon source and natural carbon sink,and the existing problems in campus are analyzed to form a new planning scheme.In the optimization scheme,active energy saving and passive energy saving are adopted for fixed carbon source,and the utilization mode of new energy,building form and building periphery structure are optimized.The optimization design of mobile carbon source includes the construction of slow-moving system and the improvement of functional layout.Optimize the design of carbon source,establish the campus water recycling system and rainwater collection system,and innovate the campus carbon management system to reduce the waste treatment energy.The carbon sequestration capacity of campus green space was enhanced by increasing green patch area in both horizontal and vertical directions and considering vegetation configuration.Finally,the optimization scheme and the current scheme are quantitatively compared and analyzed to verify the emission reduction effect of the optimization scheme.This paper studies the planning methods of reducing source and increasing sink,such as material improvement and energy flow during campus operation,providing new ideas and quantitative analysis reference for low-carbon campus design and sustainable development planning.
