Research On The Technology Strategy Of The Primary And Secondary Schools Campus Reconstruction Based On The Ecological Idea

A large number of primary and secondary schools,with a great deal of construction scale,consume enormous amounts of energy to be an important area of energy consumption.However,part of the schools have the problems of high energy consumption,low energy utilization efficiency and poor thermal comfort for the construction way behind.Therefore,schools reconstruction is of great significance to energy conservation and emission reduction,and to build a good ecological environment.By the meantime,school reconstruction is good for building up a friendly study environment for physical and mental health of the students and teachers,which is also good for setting up the saving and environmental protection awareness.Firstly,this paper studies the school reconstruction technology strategy base on ecological concept,which include building palisade structure optimization,energy utilization,utilization of resources,waste treatment and utilization,landscape ecology,green transportation and accessibility,micro climate environment,green building system etc.At the same time,through the analysis of existing problems,the essay puts forward some appropriate technical measures of school reconstruction in the view of the different aspects of technical innovation strategy.It should be emphasized that the transformation must be carried out without affecting the safety and durability of the building structure.Secondly,based on the technology strategy above,a reconstruction has been down in the Beijing Bayi school according to the actual situation.This paper take the education center as an example for the goals of low energy consumption,passive construction,energy saving and environmental protection technology in combination and green building technology promotion.According to the education center positioning itself and the basic goal,through the building site analysis,determine the design concepts and ideas,and select the appropriate technology strategy,including construction scheme,structure system,cold and heat sources,retaining structure and decoration materials,indoor environmental control,recycling energy utilization system,water saving and water resources utilization,intelligent control platform etc.On the basis of the drawings and the technical measures of education center,the indoor and outdoor wind environment,visibility,sunshine duration and intensity,indoor light environment,building energy consumption,indoor thermal comfort and harmony environment were simulated by using the PHOENICS,Ecotect,IES,CadnaA etc.The results show that,education center has a good thermal environment,and meets the basic requirements of 36.6 kWh/(m2·a)by taking a series of technical reconstruction.Besides,the indoor and outdoor wind environment,light environment,and sound environment education center are all improved,and satisfies the design requirements.Finally,according to the reconstruction plan of education center,a strategy guidance on the aspect of performance of building envelope,energy system,indoor environmental control was proposed for other buildings in the school based on the present situation.The school reconstruction with ecological idea will enable the division of students return to nature,conducive to physical and mental health of teachers and students,at the same time,form a habit of saving and environmental protection awareness from generation to generation.
