Bâdgir - Desert Cross Ventilation

A Bâdgir (also known as a windcatcher or windtower) is a traditional Persian building technology that uses wind to cool buildings in hot, dry climates. Bâdgirs are tall, cylindrical towers that are typically located on the roof of a building. They have a series of vents at the top that allow air to enter the tower. The air then travels down the tower, where it is cooled by evaporation from a water basin or fountain. The cool air then exits the tower through vents at the bottom, which are typically located near the windows of the building.

Bâdgirs are a very effective way to cool buildings in hot climates. They can reduce the temperature inside a building by as much as 15 degrees Celsius. Bâdgirs are also very energy-efficient, as they do not require any electricity to operate.

Bâdgirs have been used in Iran for centuries, and they continue to be used in some parts of the world today. They are a sustainable and effective way to cool buildings in hot, dry climates.

Here are some of the benefits of using a Bâdgir:

  • They can reduce the temperature inside a building by as much as 15 degrees Celsius.
  • They are very energy-efficient, as they do not require any electricity to operate.
  • They are a sustainable technology that has been used for centuries.
Here are some of the drawbacks of using a Bâdgir:
  • They can be expensive to install.
  • They can be difficult to maintain.
  • They are not effective in humid climates.
