In the current study, research on developing air conditioning systems by employing several technologies to cool the outdoor spaces such as public parks, the holy places and stadiums. The most serious challenge of air conditioning in outdoor spaces is difficult to control the temperature and humidity in the open spaces and also the enormous energy needed by the cooling system. The main task for the analyzed model was to ensure the better method to distribute air to achieve the human comfort for players and spectators inside the stadium and this paper was devoted to investigate the technical and economic aspects of cooling outdoor spaces such as the football stadium in Qatar. The technical aspects were addressed by developing an empirical mathematical model for the performance of stadium model. The results of the study concluded that the air conditioning system designed for Qatar stadium air conditioning was adequate to provide thermal comfort. The computational results obtained through the use of Computational Fluid Dynamics (CFD) code to predict the best way to distribute the air inlets and to simulate the air flow patterns to overcome the high ambient temperature and relative humidity to attain the human comfort.
