Washington Commons is a gathering space for the University of Washington’s Alumni Association. Embracing the University’s motto, ‘Lux Sit’ (Let There be Light), the design team created a jewel box out of an existing office space. To achieve this effect, dark and light surfaces -- as well as illuminated furniture and freestanding walls -- produce a dramatic play of light and shadow. Energy-efficient LED, low voltage, and fluorescent sources were used to minimize energy consumption. Color-changing LEDs and DMX controls provide flexibility to display the school colors or to accommodate special functions.
