During the last three decades, the world has witnessed significant economic,industrial, and technological developments. One important aspect of these developments is the implementation of modern cooling techniques. Air conditioning has been of primary concern and for this purpose, cooling systems were introduced. The volume of these systems is expected to increase of about four times by the year 2010 which is going to lead to a large increase in electric energy consumption. Cooling large open areas is really a need for the population nowadays and for this, in turn, it will lead to a huge electricity supply demand, which is a great challenge in the country with the increase in the cost of energy production. Therefore, cooling large open areas with possible economic solutions or energy alternatives will be the main subject of this study by finding a way for possible aerodynamic cooling system, which consumes much less amount of energy to provide thermal comfort to large open areas. Such as, stadiums, shopping malls, national gardens, open transportation facilities and open government facilities or even in buildings outdoor gardens.
