How to achieve natural ventilation using louvered façades?

Louvered aluminum façades facilitate natural ventilation by balancing airflow, sun control, and weather protection. Horizontal or vertical louvers—angled between 15° and 45°—allow fresh air ingress while blocking direct solar radiation. Proper spacing between blades and optimized open-area ratios of 20 %–40 % ensure sufficient ventilation without compromising privacy. In rain-prone regions, the louver capping feature sheds water, directing it away via integrated drip edges. Connecting the louver façade to an interior plenum creates a pressure-driven airflow path that cools building envelopes before mechanical systems engage. Using PVDF-coated extrusions keeps the system lightweight, durable, and corrosion-resistant. When combined with operable vents at low and high zones, louvered façades support stack-effect ventilation for energy-efficient buildings.
