What role do mesh panels play in daylighting facade design?

Aluminum mesh panels function as dynamic daylight filters that modulate incoming solar radiation and glare while preserving outward views. Their perforated geometry diffuses direct sunlight, reducing harsh shadows and lowering interior illuminance peaks. By selecting the appropriate open-area ratio—typically 15–35 % for office environments—designers can achieve a daylight autonomy target of 50–75 % without excessive artificial lighting. Mesh panels also reduce solar heat gain coefficient (SHGC), improving thermal comfort and energy efficiency. For south-facing façades, denser perforations (open area < 20 %) or multi-layer mesh assemblies further attenuate direct sun in summer while still admitting diffused light. Integrating adjustable mesh louvers allows dynamic control: users can vary panel angle to optimize daylight penetration based on time of day and season. Photometric modelling—using tools like Radiance or Dialux—helps quantify daylight levels behind mesh screens and validate design objectives. When properly engineered, aluminum mesh façades deliver balanced daylighting, mitigate glare, and contribute to occupant well-being and sustainability goals.
