How does facade integration influence daylight optimization and visual comfort in commercial interiors?

Daylight optimization is a collaborative outcome of facade geometry, glazing selection and external shading strategies. Metal curtain wall systems offer precise interfaces for integrating high-performance glazing, frit patterns, and sunshades that modulate daylight entry while preserving outward views. Strategies such as externally mounted perforated metal screens or fixed horizontal louvers intercept direct sun before it reaches glazing, reducing glare and solar heat gain while promoting diffuse, usable daylight. Glazing edge conditions — thermally broken frames and shadow-free mullions — prevent localized hot spots and glare contrasts that cause visual discomfort. Where daylight distribution is critical (open-plan offices, galleries), metal facades can house light shelves or reflective baffles to redirect daylight deeper into the floorplate, reducing reliance on artificial lighting. Daylight modeling and glare metrics (e.g., DGP, sDA) should guide glazing-to-opaque ratios and metal cladding patterns to balance view, daylight and energy.
