Research On The Energy Saving Form Of High-rise Buliding In Cold Region Based On Solar Radiation

In modern society,with the vigorous development of economy and the rapid urban construction,the global crisis of resource shortage is more and more serious,which becomes one of the many challenges that our country must face.O ffice building is an important part of modern energy consumption chain.Fortunately,the architects found the problem early,with the new technology,materials,energy using form as the guiding ideology,the architectural design process has obtained significant energy saving results.Meanwhile,as a harmless clean energy,solar energy have been more large-scale development and utilization of potential.However,at the present time,most of the solar collectors are generated by solar energy,and few solar energy sources are used as the core of the pre-design and generated from the top-down scheme guidance.In this paper,we studied the relationship between the shape of office buildings and the sunshine radiation in the cold area.Through the sampling survey of existing office buildings,we established the parameter data group of cold regions.Through the simulation experiments of various morphological elements,the optimal relationship between the parameter set and the sunshine radiation is obtained,and the method of using the sunshine resource in the architectural design stage is explored.Firstly,this paper analyzes the present situation of low energy office building design and the characteristics of architectural form in the cold area,extracts the morphological parameters of the existing office building.And then this paper establishes the research method and frame.To make a investigation and summarizes the characteristics of the regional architectural form,we choosed the representative city of Harbin in the cold area,and then obtained the ideal model of the high-rise office building in this area.The effects of plane shape changes,surface irregularities,rotating and fading changes on sunshine radiation are studied by using Ecotect environment simulation software and rhino/grasshopper morphological simulation software.Finally,the difference of morphological parameter’s sunshine radiation between winter and summer are obtained,which can provide guidance for the stage design of office buildings with low energy consumption.Through this research,the use of sunshine radiation in architectural design becomes more effective,and the architectural form has more flexible space for changing by the architect.The further development of green building design in the cold area can not be separated from the study of the office building form parameter and the sunshine radiation.Through this research,we can see the way of using environmental parameters in architecture design process has been proved to be effective,the application scope of the sunshine radiation is not limited to the technical area,and the environmental factors to participate in the process of the design of energy-saving building can be further explored.
