Sunlight Delivery System, 3M
This new daylighting solution is designed for commercial building applications. It uses a GPS-equipped rooftop collector with a single roof penetration to actively track the sun’s path. Horizontal and vertical ducts lined with 3M reflective film transports the light into a building’s interior, where it is then delivered to specific locations via multiple fixtures. The reflective film, which has a reflectivity greater than 98 percent, allows the system to carry sunlight longer distances with less light loss. A lighting-control component provides consistent light levels in dark or overcast conditions. 3marchitecturalmarkets.com
