The type of ventilation that may be used in situations where other types of forced ventilation are unavailable is secondary ventilation.
Secondary ventilation refers to the natural ventilation that occurs through windows, doors, or other openings in a building. It relies on air pressure differences created by wind or temperature gradients to drive the flow of air.
When other types of forced ventilation, such as mechanical ventilation or primary ventilation, are not available, secondary ventilation can provide a means of refreshing the air and removing pollutants from an indoor space.
