A numerical simulation and potential analysis of natural ventilation have been carried out in a typical urban gymnasiums under the conditions of hot summer and warm winter. Firstly, a numerical simulation has been made of natural ventilation in typical urban gymnasiums under two climatic conditions. Then, by comparing the airflow organization and comfort distribution of typical cities in different regions during summer, winter and transitional seasons, a reasonable wind pressure driven natural wind design strategy has thus been proposed, followed by a potential analysis of the natural ventilation of gymnasiums in typical cities under different climatic conditions.
