Skynative – brings daylight into the depths of buildings

Abstract

Abstract There are various ways of directing daylight into the interior of a building or a room. In cooperation with BASF, Bartenbach has developed a prototype of a horizontal daylight duct integrated into the suspended ceiling that efficiently transports daylight from the outside into the underexposed “core” of a building. “Skynative” is the name of the system, named after BASF spin-off Skynative® UG, which is working on market integration as well as continuous improvement of the system in an open research collaboration with Bartenbach. In this paper, the system concept development, simulation-based application studies as well as the setup of a real-scale mock-up, including results from a long-term performance monitoring at the premises at Bartenbach, are presented. First potential application projects are shown, and the system efficiency is discussed.
