I’ve just returned from the City of Yazd in Iran and as usual I have been looking at houses and buildings,

I bet you thought air conditioning is a fairly recent invention but that is what these wind tower structures have been doing for thousands of years.

Yazd is a desert city with a large variation in temperature between day and night.

During the time I was there it was around mid 20’s during the day and below 5 at night

A windcatcher can work in three ways,

• pushing airflow downward using direct wind pressure.
• pulling airflow upwards using a wind-assistance.
• pulling airflow upwards with a solar-assisted temperature gradient.

Often at the base of the wind tower there is a pool or fountain to help cool the air.

For more information about windcatchers check the article in Wikipedia
