Sunlight delivery system

3M Architectural Markets announced the introduction of the 3M Sunlight Delivery System, a new daylighting solution that captures and harnesses sunlight in an energy-efficient lighting system for commercial buildings. This sophisticated hybrid system combines multiple technologies to bring sunlight deep into interior spaces and provides consistent light levels throughout the day. The technology holds promise for both energy efficiency and improving the productivity and morale of building employees, according to a company release. The 3M sunlight delivery system provides the industry with a new method of daylighting, actively tracking, capturing and transporting the sun's natural, full visible spectrum daylight beyond just the top floor and into the interior spaces of buildings where natural lighting is limited. The system uses a GPS-equipped rooftop collector with a single roof penetration to actively track the sun. Horizontal and vertical ducts lined with 3M reflective film carry the light into the building's interior, where it is delivered with multiple light fixtures. These highly reflective films—with a reflectivity greater than 98 percent—enable the system to carry sunlight for long distances and with less light loss.
