Windcatcher - Wikipedia

In Iran, a windcatcher is called a bâdgir: bâd "wind" + gir "catcher" (Persian: بادگیر ‎). The devices were used in Achaemenid architecture. In Iran, they are used in the hot, dry areas of the Central Plateau, and in the hot, humid coastal regions. Central Iran shows large diurnal temperature variation with an arid climate.Get price

How Iranian architects invented ways to stay cool | British

Homes in Iran are designed to keep people cool in the heat In Iran, houses co-evolved with their surroundings over time. Each house and its environment are indivisible: the orientation of houses is determined by the available shade, the direction of the sun, and the flow of wind, so that they provide the most comfort at all times of the year.Get price
