Building facades regulate important building functions, such as daylighting provision, glare protection and solar heat gain management. Switchable facade elements in combination with a control strategy must be considered in order to dynamically balance these functions, which are of varying relevance, depending on the time of day and season. This paper presents an overview of the Fener tool, which was specifically developed for the design and evaluation of innovative fenestration systems and their control. The Fener tool is a building simulation program that couples daylighting and thermal calculations on a time-step basis, including thermal inertia calculations. This makes the tool particularly useful to assess innovative control strategies that depend at the same time on thermal and daylighting variables. The tool can calculate the impact of a fenestration system on the daylight availability, glare risk, thermal comfort and energy demand of a room. In this study, the Fener tool is used to develop control strategies for an innovative angle-selective and switchable textile technology. The control strategies are specific to the use of the building. Two different building uses are analysed: an office and a hospital ward.
