Study On Section Design Strategy Of Sports Hall Of Small And Medium-sized Gymnasium In Southern China Based On Natural Ventilation

At present,with the promotion of the high-quality development of sports in China,people’s demand for the construction of small and medium-sized stadiums continues to increase.At the same time,the frequent occurrence of sudden public health events has increased the demand for indoor air quality.Aiming at the optimization of indoor natural ventilation,this paper has certain practical significance for the research of section design strategy of sports hall in small and medium-sized gymnasium.This paper first combs the three basic principles of indoor natural ventilation and describes the characteristics of ventilation environment in the southern region.On this basis,this paper establishes the natural ventilation evaluation standard of the southern sports hall according to the domestic ventilation code,and summarizes the influence factors of section design on the natural ventilation of the sports hall.Then,through software simulation and variable control,this paper analyzes the relationship between the vertical design,architectural form,window form and interface structure profile design elements and the natural ventilation of the sports hall,and obtains the relative optimal value of each element.Finally,this paper proposes the section design strategy of the sports hall from four aspects of vertical design,architectural form,window form and interface structure based on the case.To optimize the design of the vertical including reasonable configuration function and conform to the topography,including the use of optimization architecture form clear height,roof,roof overhang and tumble in metope,optimize the window forms including optimization,using convex skylight window type,concave and convex side window and shutter,optimizing the interface structure including additional cavity,guide the wind component,using ventilation Settings interface and using the landscape.
