traditional cooling structures are among the most
conspicuous features of Yazd, giving the city a totally
distinct appearance from other Iranian cities.
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.
shafts have four parts: body (or trunk), air shelves,
flaps, and roof.
