This filter modulates the incident daylight in the temporal domain, e.g. by shielding the interior from solar radiation on sunny days, and spatially, e.g. by redirection the transmitted light to balance the illumination of the interior. Established, but simplifying planning aids, such as Daylight Factor cannot account for the variable exterior conditions and therefore cannot provide insights into the eventual availability of daylight in buildings. Accordingly the Competence Centre applies climate-based metrics, that take for the local environmental conditions into account and allow for the prediction of absolute photometric quantities to estimate daylighting performance.
The Competence Centre conducts research in close collaboration with its international partners. Topics include the development, characterization, modelling and evaluation of daylighting techniques, that turn glazed facade components and roofs into daylight modulating building skin. With our know-how as well as our infrastructure, e.g. the gonio-photometer laboratory, we support manufacturers in the development and planners in the application of innovative daylighting.
