have many styles and different functioning. The

picture below shows the most known ones:

A. Unidirectional.

B. Two-directional.

C. Four-directional.

D. Octagonal with two vents on each side.

Functioning Systems of Badgirs

Cooling by evaporation:

Badgirs have vents on side from which the wind blows and on the opposite side. During the day

time; the wind enters the building and evaporates water causing a decrease in temperature inside the

building. This style of Badgirs is dominant in dry hot regions.

Cooling by ventilation:

Inside a building, the hot air rises because it is less dense whereas cool air sinks down since it is

denser. When there is no wind outside, Badgir allows the hot rising air to expire from the vents

leaving behind only cool air and thus the inner environment cools down. This type of Badgirs is

usually found in humid and warm regions.
