The ventilation and cooling in the traditional architecture of the Persian Gulf

History devices, modeling, performance evaluation.

Built on the roof, a Badgir captures wind from any direction and guides it to the occupant’s zones.

In persian, Bad = wind and Gir = to catch, thus, Badgir or windcatcher…

Iranian wind towers are designed to introduce cool outside air, driven by relatively high wind pressure. The internal partition allows the low pressure on the lee side of the tower to suck air from inside the building.

Badgirs are directly related to a living space , called “Badgir’s room”.
The turbulence induces hot air extraction outwardly from the opposite channels.
Operation of a Badgir during the day and at night.
Marine breezes direction reverses between day and night.
