It is said that Yazd has more winds than any other city in the world.

From ancient Egypt to the Persian Empire, an ingenious method of capturing and directing the wind has been refreshing people for thousands of years. In the search for emission-free cooling, the “wind catcher” may come to our aid once again.

The city of Yazd, located in the desert of central Iran, has long been a center of creativity. Yazd is home to one of the wonders of ancient engineering – a system that includes an underground cooling structure called a yakhchal, an underground irrigation system called qanats, and even a messaging network called pirradazis, established more than 2,000 years before the US Postal Service.

Among the ancient techniques of Yazd is the wind trap, or badgir, in Persian.

These magnificent structures are commonly found on the roofs of Yazd. Most often they are rectangular towers, but they are also found in round, square, octagonal, and other ornate shapes.
