A passive ventilation system relies on natural forces, such as wind and temperature differences, to provide air movement within a building.

Unlike mechanical ventilation systems that require active components like fans, passive ventilation systems utilise passive design strategies and elements to facilitate airflow. They’re particularly useful in moderate climates and buildings where mechanical ventilation is impractical. For more information, check out our complete guide to passive ventilation systems.
