Birkerød Aktivitetscenter, Denmark ”The modern curtain” Finished in 2007 The Activity Centre of Birkerød is a project by Schmidt Hammer Lassen Architects, Denmark. The decorative effect of the sun blinds, which consists of modified glass fibre lamellas, works not only at daylight but also during the night. The sunlight “projects” the integrated pattern through the translucent lamellas to the inside of the building. During the night the illumination of the inside will make the same pattern visible from the outside. Adapted to the big radii of the construction the design of the pattern underlines the smooth shape of the building itself. Each window section is 8 m high and 1,5 m wide and the whole facade will have a size of ca. 1000 QM.
