Office Building in Ginza

Yoshihiro Amano 

Situated on a commercial street of Tokyo, the building breaks with the area’s characterless image by means of a facade of faceted and seemingly random shapes that serve as a visual announcement. The envelope is formed by two layers separated by a chamber. This arrangement makes it possible to protect the building against solar radiation besides inducing an indoor ventilation current that dissipates part of the building’s thermal gains. Completely conventional, the envelope’s inner layer consists of large stretches of curtain wall; the outer one, much more exceptional, is a conglomerate of aluminum trays perforated in different patterns and fixed to the edges of the slabs by means of a very light structure based on rafters and steel cables. Different in size and in patterns and degrees of perforation, the trays are protected by computer design programs and fabricated by robot processes. LED batteries placed in the chamber illuminate the facade at night.
