A modern approach based on a “bookstore model” was adopted for the new 10,000-sf design. The exterior reads as a collection of smaller buildings, each with its own unique shape. Exterior materials include stone, stucco, brick, and metal siding. The program features an entry vestibule with a 15-foot-tall mobile suspended dramatically from the high ceiling, a large main reading area, and separate reading rooms for youth and children.  Boldly patterned furniture and customdesigned display fixtures enliven the interior spaces. Carpet with a typographical pattern is used throughout the library with contrasting circular insets to help define different areas. The project employs a variety of sustainable design strategies, including a 25.2 kW photovoltaic system that is expected to generate approximately 32,000 kilowatt hours annually (power sufficient for about three standard sized homes), large roof overhangs, a daylight-responsive lighting-control system, and rainwater harvesting. Additionally, large wood trusses reclaimed from a 100-year-old Mississippi river barge support sound absorptive structural insulated roof panels (and saved the equivalent of about 30 large trees). A neighborhood pocket park, amphitheater, and rows of shade trees complement the new building. tects, Floor Plan 1 Main Entrance 2 Meeting Room 3 Childrens’ Area 4 Work Room 5 Mechanical 6 Electrical 7 Mechanical Yard 8 Covered Porch 9 Teen Area 10 Reading Garden 11 Cistern 11 5 7 9 11 10 8 7 4 4 5 6 3 1 2 Resources masonry units: Elgin Butler Brick ; manufac- tured stone : Arriscraft International ; roof deck : Tectum (Maniscalco & Associates); roofing: Kidd Roofing; building Noelle Heinze insulation : Johns Manville ; entrances/storefronts: Kaw- neer; glass: PPG Industries; hand crank window hardware: Dayton Metal Products; tile: DalTile; acoustical ceilings: USG ; carpet : Millikin Carpet; waterproofing/stucco: Sto Corp.; plaques: TakeForm ; signage: 3-Form, Peter Pepper Products; operable partitions: Modernfold; toilet partitions: Bobrick ; library equipment : Kingsley Library Equip- ment, Peerless Sales Co.; blinds: Mechoshade ; furnishings: Agati (Mezzacappa Design) 3/4 2012 Texas Architect 61
