DUVALL LIBRARY
DUVALL LIBRARY Duvall, WA 8,291 sq ft
The inherent civic nature of a library helped to shape the design of the Duvall Branch. Located within the historic district of Duvall, the new building showcases the importance of the structure to the town through its elemental yet expressive form, and the use of weathered materials that complement the historic fabric. The roof accentuates the entrance and responds to the natural topography of the site. The library is two stories, with public uses on the ground floor, oriented to the sidewalk, and mechanical systems tucked away on the upper level. Active program elements, such as the reading room and children’s areas, are located along Main Street--the primary route of travel through the town--to allow a strong visual connection between interior and exterior and to draw from the activity of each. The library was designed to meet LEED Silver standards. A ground source heat pump, coupled with energy efficient interior lighting, reduce the building’s electrical usage by 40%. The heat pump relies on 300’ deep geothermal wells, located in the parking lot. Large awnings and interior suspended ceilings control sunlight and heat exposure; LED lighting and daylight sensors are used wherever possible. Recycled, salvaged, and lowVOC materials were installed throughout to provide building occupants with the healthiest possible indoor experience. Lastly, a green roof helps replace area lost by the building footprint and slows stormwater runoff. The hardy mix of sedums require minimal water and upkeep; thanks to the steep topography, its visible to human passersby at grade.
