Designed on an extremely tight budget to increase interest on an otherwise plain office building, the Nogales Shade Canopies draw from the history of Nogales, Arizona and also shade to improve the energy efficiency of the building. Laser cut patterns are derived from real walnut leaf patterns in response to the native trees that historically populated the region. The canopies on the west-facing windows are calibrated to respond directly to the Arizona sun by locating screens above, adjacent to, and partially in front of each window.
