What is Windcatcher?

Windcatcher refers to a type of architectural element used to create natural ventilation in buildings, particularly in hot and arid climates. It's a tower-like structure on the roof that captures prevailing winds and directs them downwards into the building's interior, providing cooling. Hot air inside the building is then displaced and rises out of the windcatcher, creating a continuous airflow. They are a traditional method of passive cooling.
