  1. 1. George Washington Carver Branch Library LEED Performance Report BROUGHT TO YOU BY THE OFFICE OF THE CITY ARCHITECT
  2. 2. ACKNOWLEDGEMENTS The following Performance Reports were created in accordance with Council Resolution 20071129-045. The City of Austin is a recognized international leader in sustainable building practices in which municipal building strive to conserve energy, water, and other natural resources while promoting human health and safety. The holistic approach to architecture creates high-quality and enduring structures that enhance the economic value and reduce the lifecycle costs of a building. Design and construction of buildings are driven by the United States Green Building Council’s (USGBC) Leadership in Energy and Environmental Design (LEED) guidelines and promote these goals. The following reports provide information about municipal buildings, highlight LEED credentials, and promote sustainable building achievements.

  4. 4. GEORGE WASHINGTON CARVER BRANCH LIBRARY 1161 Angelina Street, Austin, TX, 78702 LEEDv2 New Construction AWARDED LEED CERTIFICATION JUN 2006 CARTER • DESIGN ASSOCIATES The George Washington Carver Branch Library, located in and owned by the City of Austin, Texas, is one of many branch libraries run by the City's Library Department. It began with the request made by the surrounding African-American neighborhood when a new main library building was built in 1933. After outgrowing the small 1,896 sf building, the current branch library building was constructed in 1980. The original structure was converted into the George Washington Carver Museum and has continued to serve the Austin community. This project remodeled and added to the 1980 facility. The Carver Library has had from its inception a unique relationship with the surrounding neighborhood in that it has a large meeting room space and functions similarly to a community center - hosting a variety of events such as club meetings, family gatherings, and public events. The building is a recycled steel frame and steel stud infill with a locally manufactured masonry veneer of cement plaster and existing brick. The foundation is fly ash containing concrete pier and beam with a poured-in-place suspended concrete slab floor. It has built-up roofing. A new steel canopy, automatic doors, and frit glass in a thermally broken curtain wall are used as a new entry element. Interior finishes are minimal, durable, and easily cleaned. The existing library had brick interior walls that were retained wherever possible. The interior has carpet tile for easy replacement of high use areas without requiring a complete replacement, thus extending the overall life of the carpet. Both the carpet floor and acoustic panel ceilings were chosen for sound attenuation.
  5. 5. Emissions and cost are reduced by decreasing energy use through improved design. Emissions are further eliminated by contracting 100% of the building’s energy to a renewable source.
