Research On The Space Form Design Of Educational Buildings Based On Natural Ventilation

With the promotion and development of green buildings and regional architectural creation,people began to reflect on the origin of architectural creation.Architecture is a tool to adapt to the climate and a refuge for human beings.Therefore,regional architectural creation adapted to the environment is the core of architectural design.There are many factors that affect the design of regional buildings.Adhering to the design concept of green building source reduction,climatic factors,site factors and response strategies should be considered at the initial stage of the architectural plan design.We should make full use of natural climate conditions,tap the potential of low or even zero energy consumption in the site,analyze the building form and existing problems in combination with the actual situation of the site environment,and use corresponding strategies to solve different problems.Based on the design concept of natural ventilation and source reduction,using literature reading,case analysis,software simulation and other methods,this article takes the basic form of the building as the research object to study the spatial organization mode and design method of educational buildings in colleges and universities in severe cold areas.This paper makes a comparative study on the application and measures of natural ventilation in buildings,combined with software for simulation analysis of ventilation performance,and interprets the internal mechanism of mutual determination and influence between the architectural wind environment and the architectural space organization.By sorting out and analyzing relevant research at home and abroad,and summarizing universal space design strategies,we pointed out that educational buildings in severe cold and cold areas need relevant design research.We refer to related theories and strategies,and take Hohhot as an example to analyze the spatial organization mode of the third-phase experimental building of the School of Architecture of Inner Mongolia University of Technology.We have taken indoor ventilation efficiency as the benchmark,using fluent airpak3.0 software to simulate the wind speed cloud chart and wind speed cloud chart of different spatial organization modes inside the building under natural ventilation conditions.In addition,the index of indoor ventilation frequency is calculated statistically.The simulation results show that,on the basis of the north-south transparency scheme,the ventilation benefit is the greatest under the integrated organization mode of atrium,split-level,and chimney,and the natural ventilation state can meet the indoor ventilation requirements.At the same time,we summarized the regional spatial strategies suitable for the natural ventilation design of university buildings in Hohhot.On this basis,the design strategy of educational building space form based on natural ventilation was summarized from four aspects of outdoor wind environment,indoor space design,interface space design,and natural ventilation control in winter.And the application design was carried out on the transformation of the teaching building of the Inner Mongolia University of Technology Research Office Apartment Building.Without using the refrigeration equipment such as air-conditioning in the short hot period of summer in the area,the optimization of the internal space organization mode of the teaching building of Inner Mongolia University of Technology is studied.The atrium and the interlayer spatial organization mode were designed for the traffic space and the use space,which not only formed the wind,but also increased it.The effect of heat pressure improves the space wind environment on the leeward side.Comparing the simulation results before and after the transformation,the overall ventilation effect of the room after the transformation has been significantly increased,indicating that the design transformation scheme is reasonable and effective.Through sustainable design and optimization,natural ventilation is used to supply sufficient fresh air in the room,it can improve the comfort of the building,reduce unnecessary waste,and reduce environmental pollution.The realization of green energy saving in the early stage of architectural design will revitalize the campus,help to broaden ideas,and provide a certain reference for regional architectural creation.
