Badguir (Badgir)
These traditional cooling structures are among the most conspicuous features of Yazd, giving the city a totally distinct appearance from other Iranian cities.

Old residential quarters and the city's traditional water reservoirs all have weathering shafts, which are indeed Yazd's breathing outlets. These structures are small towers, which are designed in such a way as to blow the natural air current into the building. Yazd's ventilation shafts are indeed worthy of being mentioned as best examples of efficient clean energy systems.

The shafts have four parts: body (or trunk), air shelves, flaps, and roof.
