Research On Suitability Technology Of University Green Campus Reconstruction In Hot Summer And Cold Winter Region

Green campus refers to maximizing resource conservation（energy saving,water saving,material saving,and land saving）,protecting the environment,reducing pollution throughout the life cycle of the campus,providing healthy,applicable,and efficient environmental education functions and natural resources for teachers and students.A campus with a coordinated environment.Different from the single building,the main body of the green campus is the campus.It not only includes the single building with different functions,but also includes a certain regional environment.It also involves different functional requirements such as education and accommodation.Therefore,the green campus has the research value beyond the green building,and the ecological park and eco-city belong to the same level^[51].At present,China’s university campus buildings have large stocks,high energy consumption,and the construction period is generally long.Most of the campuses were built in the middle of the last century.There are energy shortages caused by ageing,space abandonment caused by functional changes,and early construction.Technical limitations have led to problems such as energy saving in buildings.Therefore,the reform of the green campus of colleges and universities is of great significance to the reform of the ecological civilization system proposed by the 19th National Congress and the construction of beautiful China.The green transformation of the university campus should not be a hard copy.Due to the economic development,climate environment and topography,the technical strategies adopted by the different regions are not the same.In order to make the buildings more fully utilize and adapt to different climatic conditions in China,to achieve the purpose of adapting to local conditions,China The climatic zone division of China in the General Principles of Civil Building Design is divided into seven climatic zones.The hot summer and cold winter zone belongs to the north-south junction.This area is hot in summer and cold in winter,with four distinct seasons.It has a cold in the north and a south.In the heat of the building,it is necessary to consider the construction of the cold building to keep warm,but also to consider theheat of the building ventilation and the insulation of the envelope structure.It has high complexity and researchability,so this study focuses on Analysis of hot summer and cold winter areas.Combined with the technical evaluation items of the university’s green building in the Campus Green Evaluation Standards,through the investigation and research on the commonly used green technologies in the regional case campus,the commonly used green technologies are divided into active technology and passive technology according to the actual project situation.Through the simulation of the actual building in the CGB integrated technology platform,the suitability of the transformation technology is judged,and the corrective measures and opinions for the suitability green transformation are given for the selected actual case campus.The paper is divided into five parts,which are mainly discussed from the following aspects:The first part is the first chapter of the full text.From a macro perspective,we will sort out the relevant policy background and standardization of the university green campus.By analyzing the development of related fields at home and abroad,and reviewing the literature and related norms of climatic conditions in summer hot and cold winter regions and other regions,determine the research direction and research purposes,thus determine the research methods and determine the objective for campus energy-saving transformation.condition.The second part is the second chapter and the third chapter of the full text.The campus construction conditions in the hot summer and cold winter regions are analyzed.In order to obtain the intuitive feeling of campus users on the construction of green campus,a questionnaire survey was conducted on the sample colleges,and part of the field survey of the sample campus was conducted for the green building technology commonly used in actual construction,and from the active and passive aspects.The technology is classified to provide basic data for the establishment of the campus CGB model and the subsequent comparative analysis of the simulation results.The third part is the fourth chapter of the full text.The implementation method of CGB software integration is discussed.The basic data collected in the previous stage is used to propose the transformation plan for the unreasonable situation of the case campus,and the transformation plan data is imported into the CGB technology platform to simulate the partial transformation plan of the campus.Through the simulation results,the suitability of green building technology in the transformation is discussed.The fifth part is the sixth chapter of the full text.Combine the previous strategies for adapting the actual project,sum up the reform strategy system,and propose the focus of suitability transformation from the aspects of building environment,enclosure structure and resource utilization.At the same time,this chapter summarizes the research work and passes The lack of analytical research provides a direction for further research.
