Green Libraries: Scottsdale (Ariz.) Public Library, Appaloosa Branch

The projects featured in this section each exhibit interesting approaches to sustainability.

The metal-clad skin of the new Appaloosa branch of Scottsdale (Ariz.) Public Library is the first U.S. commercial application of the Vari-Cool iridescent coating from PPG Industries, which consists of mica chips in a clear base that creates shifting colors depending on the angle of view, while reflecting infrared light. A convective cavity separates the panels from the building so heat can disperse before reaching the insulation. The building has been submitted for LEED Gold certification; additional green features include native vegetation and cacti and trees salvaged from the lot’s prior use, oversized ductwork to slow air flow and lower energy consumption, locally produced building materials, and a photovoltaic array on the roof.
