3M Architectural Markets has released its Sunlight Delivery System, a hybrid daylighting solution that uses GPS to track and collect sunlight, potentially reducing peak energy demands. The collected light is carried through horizontal and vertical ducts—lined with 98% reflective film—to a building’s interior and delivered via multiple apertures. The system incorporates artificial lighting sources to maintain lighting levels in dark or overcast conditions and can transmit light five stories into a building. •
