Studies On The Energy-saving Evaluation System Of Campus Building From The Perspective Of Carbon Footprint

With the continuous development of higher education,the state attaches great importance to the field of education.The volume of campus buildings,especially the number of University campuses,and the number of faculty members have increased significantly.The problem of energy consumption has become more and more significant.The public expenditure and energy expenditure have been greatly improved,even increased several times.The development of industry has brought about greater energy consumption,and the special use function of eampus determines that its per eapital energy eonsumption is higher than the average level of society.At present,most of the targets of energy saving and emission reduction on campus in China are aimed at reducing the total energy consumption of the actual use of buildings in a year,but lack the basis of carbon footprint control by stages.Due to the persistence and large volume of carbon emissions in each stage of campus building production activities,continuous monitoring of building energy consumption can quickly reflect the energy consumption situation of campus buildings.Through the energy monitoring platform,real-time monitoring data changes can be monitored,dynamic adjustment and screening of key influencing factors can help to further study and determine an effective energy-saving evaluation system and reduce the carbon consumption of campus buildings.Emissions and energy conservation are of theoretical and practical significance in the long run.Firstly,this paper combs and calculates the forms of carbon emissions in different stages of the whole life cycle of individual buildings,classifies and explains the influencing factors and interaction relationship of carbon emissions in each stage,which runs through the stages of-pre-planning,planning and design,construction,operation and maintenance of buildings,and demolition and cleaning in time.Because it is difficult to quantify carbon emissions in the planning and design stage,the carbon emission measurement and carbon emission quantification indicators in this paper only include the latter three stages.Based on the perspective of carbon footprint,the carbon emission quantification indicators in each stage are proposed.Based on the analysis of building carbon footprint,this paper makes full use of the carbon emission measurement results and the actual energy consumption data provided by the campus energy monitoring platform to distribute the weight of each evaluation index in real time and dynamically,improves the limitations of the existing static average weight evaluation model,and constructs a dynamic weight evaluation system for campus building energy efficiency.Highlighting the energy consumption and energy saving potential in the operation and use stage,focusing on the refinement of specific energy consumption indicators of water,electricity and gas,and expanding its quantifiable scope.It is helpful to improve,reduce and control the carbon emissions in each stage by using the method of fuzzy comprehensive evaluation and putting forward the emission reduction strategies in each stage.At the same time,the future development direction of building energy conservation should not be limited to annual energy consumption.The perspective of life cycle carbon footprint proposed in this paper provides energy-saving managers with a scientific and effective perspective to evaluate the target buildings from the initial stage of construction to the whole process of future operation.The sustainable dynamic evaluation of Campus buildings can also provide reference and improvement direction for future energy conservation and consumption reduction.
