yazd Wind catchers or Badgirs

Wind catchers are ancient natural air conditioning systems designed for hot areas. The structure catches even the lightest breeze and directs it to the rooms below. 

 

Summer visitor to Yazd can easily feel the need for cool air. The towers consist of four parts: the body or trunk that contains the shafts; air shelves that are used to catch some of the hot air and prevent it from entering the house; flaps which redirect the circulation of the wind; and the Covering. The flows which enter the building go above a pool of cool water, thereby cooling the surrounding air, while the warm air continues its circular path, redirected upward through a different shaft.
