How facade shading and daylight control improve indoor working environments

Effective shading and daylight control increase occupant comfort and productivity by reducing glare, stabilizing daylight levels, and limiting unwanted solar heat gain. External metal shading—fixed fins, adjustable louvers, and perforated screens—blocks direct sun before it reaches glazing, which is more effective than internal shading for daylight control and cooling load reduction. Perforated metal screens can be tuned to balance daylight diffusion with view retention, providing a refined visual character to the façade.

Integrating shading into the metal curtain wall assembly enables precise alignment with mullion lines and simplifies maintenance. Combining shading with spectrally selective glazing and daylight sensors tied to lighting controls produces a holistic strategy: daylight is harvested when beneficial and artificial lighting dimmed accordingly, saving energy and improving user comfort. For office fit-outs where visual comfort matters, collaborating with façade engineers early to model sun paths and daylight yields yields the best outcome.
