Extrusion International 3-2018

41 Extrusion International 3/2018 Human centric lighting concepts Human centric lighting (HCL) refers to holistic lighting concepts that put the emphasis on hu- mans and their well-being. HCL encompasses the visual, emotional and biological effects of light. BASF’s daylight system can contribute to improv- ing spatial quality in places such as schools, hospi- tals, shopping malls and office buildings. Because people feel better in natural light, they concen- trate better, are more motivated to work and less likely to get sick. Furthermore, using natural light over the course of the day enables artificial light usage to be reduced by significantly more than half. The consulting firm A.T. Kearney has calcu- lated that the benefits of HCL to the general pub- lic could be as high as €870 million in Europe in 2020. Wide range of design possibilities for architects This system enables daylight to be transported far into the interior of buildings without requir- ing any additional structures on the facade. Inside the building, the system can be used flexibly – ei- ther concealed within a suspended ceiling or as a visible element as part of the interior design of the building. Through the light fixtures, daylight can penetrate into areas far from windows as well as hallways and rooms without natural light. The system can be integrated into existing facades and new facade concepts without limiting design options. In addition, it creates possibilities for new design concepts, such as office environments with working and lounge areas that include natu- ral green zones to improve quality of life. From idea to market-ready system solution The idea for the daylight management project emerged during the Creator SpaceTM program put on by BASF in 2015 to mark its 150th anni- versary. Based on this idea, teams from Switzer- land explored the topic of light and energy inside buildings. Together with BASF experts from vari- ous specialist units, they created a concept that became an incubation project and was developed into a market-ready system solution. An initial prototype is already being used in the headquar- ters of Bartenbach GmbH in Austria.
