What type of ventilation is most effective in promoting air exchange during windy conditions?

Explanation:
Louvers are designed to allow for passive ventilation while effectively promoting air exchange during windy conditions. Their angled slats help deflect rain and direct airflow into the building, maximizing the entrance of fresh air while preventing water intrusion. On windy days, the increased pressure can help push air through these openings, enhancing the overall ventilation within the structure. In contrast, static vents may not be as effective during high wind situations since they rely on natural air currents without any mechanical assistance. Power fans can improve airflow but depend on electrical power and may not always be practical or necessary in windy conditions. Ridge vents, while beneficial for hot air escape from the roof, often don't perform optimally in all wind directions and may need supplementary airflow options to be fully effective.
