Natural cross ventilation

Natural Cross-Ventilation

Natural Cross-Ventilation occurs when air enters through openings, such as windows and doors, on one side of the building and exits on the opposite side. It is driven horizontally by positive pressure on the windward side and negative pressure leeward side of the building, as well as vertically through the building via stack effect. Natural Cross-Ventilation reduces energy-consumption for artificial cooling and ventilation during summer months. Buildings are ideally designed to encourage Natural Cross-Ventilation through their relationship with prevailing breeze patterns.
