40 Extrusion International 3/2018 RAWMATERIALS, FILM BASF presented innovative daylight management system with a 1:10 scale model on display at the Light + Building trade fair in Frankfurt/Main, Germany Howcannatural daylight bebrought intobuilding interiors soevenwindowless rooms donot need artificial light during theday?Andhowcan sunlight beusedoptimallybehindglass facadeswithout creating glare? BASF has found a smart solution to these two problems. The system is based on the principle of light guidance and comprises three components: a film, a light shaft and light fixtures. The film is embedded in insulated glass and optimally guides the light from there into a light shaft containing reflective film. The shaft brings sunlight deep into the interior of a building, where light fixtures shine the daylight into the rooms. These light fixtures are also equipped with LED lamps that provide light in the rooms when natural daylight is unavailable or insufficient Innovative Light Guidance System illuminates Windowless Rooms
