What does wind ventilation utilize to move fresh air within a building?

Wind ventilation relies on the principles of aerodynamics to facilitate the movement of fresh air through a building. It exploits changes in air pressure and prevailing wind patterns to create a natural flow of air into and out of spaces. As wind moves across a building, it generates positive pressure on one side while creating negative pressure on the opposite side. This difference in pressure allows air to enter through openings such as windows, doors, and vents, enabling effective air exchange without the need for mechanical systems.

Understanding this natural process is essential in indoor air quality management. By harnessing wind ventilation, buildings can effectively reduce indoor pollutants and enhance occupant comfort through a systematic exchange of stale indoor air with fresh outdoor air. This method emphasizes the importance of strategic building orientation and placement of openings to optimize airflow and enhance ventilation naturally.
