The quality of daylight is an important part of the design. On upper floors, classrooms have high curved ceilings and tall windows letting in plenty of daylight and creating attractive learning spaces. The central mall is flooded with light through a curved glazed roof, where prismatic glass allows in low winter sun but reflects most of the summer sun. Glazing between classrooms and the mall provides some borrowed light into the back of classrooms, and more importantly a view into classrooms.
