Study Of Passive Energy-saving Design During Existing Buildings Renovation In Lingnan Campus

China's colleges and universities construction scale is growing,and the face of urban development and transformation,environmental pollution,lack of resources,the objective social status quo,to create a green-saving campus,has become a higher goal and requirements of colleges and universities.And for the function,space,structure,energy and other aspects of the requirements of a large number of colleges and universities existing buildings to implement a comprehensive transformation,and the use of mature green energy-saving technology to enhance the overall comfort of existing buildings,and then reduce building energy consumption,Sustainable development concept,is undoubtedly a better choice for the construction of colleges and universities.Among them,the passive energy-saving design,pay attention to the building to adapt to the natural environment,the winter without heating China's Lingnan region,is particularly important.Therefore,the research on the passive energy saving design in the reconstruction of existing buildings in Lingnan University can provide substantive guidance for Lingnan University to build green saving campus.In the context of the green building concept in the construction of colleges and universities more and more attention,the author of Lingnan a number of colleges and universities and the existing building renovation case of field research,data collection and literature research.Through the combination of longitudinal research and horizontal research,we first put forward the development of passive energy-saving technology in Lingnan colleges and universities,find out the existing problems of existing buildings in Lingnan University and the design focus of passive energy saving in existing buildings.Finally,combined with several outstanding examples of existing buildings in Lingnan University,this paper analyzes the design scheme,the computer simulation analysis and the energy efficiency detection after the completion of the project,and analyzes the factors influencing the passive energy saving design of the existing buildings in Lingnan University.The layout of the building layout,the optimization of the internal space and the improvement of the envelope structure,and puts forward the strategy of passive energy saving design in the reconstruction of existing buildings in Lingnan University.Strategy,which will help to transform existing buildings in Lingnan University and realize the energy saving of colleges and universities,and provide some reference and reference significance.
