Design Strategy In Stadium Interface Morphology On Ventilation

The energy consumption of the stadium is much greater than the average building based on its large space, which leads to their indoor air environment regulation equipment investment accounted for a large proportion of energy consumed in operations. Therefore, how to meet gymnasium hall technology and comfort requirements of the current problems by minimizing energy consumption and using natural ventilation is the important consideration. This paper is mean to explore inherent synergies between sports architecture interface morphology and natural ventilation. Through the use of CFD simulation method, starting from the Coliseum natural ventilation problems, as a platform to roof shape and opening the way for the factors, gymnasium hall technology standards and comfort to the criteria, comprehensiving building HVAC expertise simulation experiment study, and strive to provide the basis for stadium sustainable design.In this paper, select the stadium screen form as the study, through the rational use of numerical simulation software to simulate the relevance of stadium interface morphology and natural ventilation, which as a basis to propose viable design strategy. Firstly, learn the clear correlation between natural ventilation and gymnasium architectural design, select Fluent experimental software and verify the feasibility of the software. At the same time, construct a reasonable complete experimental system, experiments to determine the physical model, boundary conditions, and other physical parameters of the discrete and make the roof form and manner as the opening of factors, stadium technical standards and comfort as the criteria. Secondly, select the form of roof and the opening as variables to experiment. The simulation including pressure experiment, wind speed experiment, ventilation frequency experiment and so on. Finally, summary and analyze the simulation data and then propose design countermeasures. At the same time, choose the builted stadium and improve it according to the design countermeasures and then compare the improved model with the original model to verify the feasibility of countermeasures.Based on the theory of stadium interface morphology, not only energy consumption can be reduced, but also technology and comfort improved. And the same time it can provide certain reference value in sustainable building design studies.
