Earlier today, we posted about a pavilion built from outdated Speedos. Last week, Cool Hunting spotlighted a similar effort on the part of Levi Strauss & Co., which used recycled denim to insulate their renovated San Francisco headquarters. Throughout the building, as a testimony to the innovative nature of its construction materials, designers installed plexiglass windows that reveal the denim underneath the surface. The Academy of
Sciences building in Golden Gate Park, re-designed in 2008, also features insulation made from re-used Levi's rather than new materials.
