This contribution presents a case study on lighting levels and visual comfort in a set of indoor sport facilities in Vienna, Austria. The primary objective of indoor lighting design is to provide satisfying illumination conditions fitting to the specific requirements of different, corresponding spaces. Furthermore, elaborated lighting solutions can help to reduce a building´s operational cost and environmental footprint, if utilizing available daylight and energy-efficient luminaire technologies. In the case of sport facilities, additional aspects, such as the safety and performance of the athletes, the protection of luminaries against damage, maintenance levels, the comfort for spectators, and the requirements for live broadcasting need to be considered. In this study, 5 representative indoor facilities of the University Sports Institute of the University of Vienna were examined towards their lighting performance in view of the mentioned aspects. These facilities are all located in a large complex erected in 1973 and retrofitted around the millennium. They include halls with different geometry and purposes, luminaries, window orientation, surface structures, and roof geometry, as well as a large indoor swimming pool including diving platforms. Hereby, illuminance measurements during day- and night time, as well as state-of-the-art simulation tools were utilized. These efforts offered possibilities to compare the status quo with requirements and recommended lighting conditions, and to partly calibrate simulation results with real measurements. As a result, strengths and weaknesses of the existing lighting solutions could be evaluated and optimization potential could be identified.
