Shopping mall foodcourt. Clerestory windows with low-e grey glass above the foodcourt. Overall light transmittance is reduced but the direct-beam light that does arrive at table level is sufficiently glaring as to keep potential customers away. Mall owners and retailers suffer from lost revenue.
Solera in clerestory brightens the entire foodcourt with diffuse daylight. Natural light improves shoppers' sense of well-being, while glare-free space invites them to have lunch and continue shopping rather than going home. Daylight harvesting is an option.
