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. AUSTIN CITY HALL & PUBLIC PLAZA 301 West 2nd Street, Austin, TX, 78701 LEEDv2.0 BD+C: New Construction AWARDED LEED GOLD AUG 2006 PREDOCK, COTERA + REED ARCHITECTS Situated in the former warehouse district of downtown Austin, the Austin City Hall is a 115,000 sq. ft., four-story office building with 300 full time employees, including the Mayor, City Manager, City Budget offices, and the Legal Department. The building consists of a large atrium, plaza, telecommunication rooms, internally located mechanical rooms, electrical space, and an underground parking garage. Comprised of approximately 1.74 acres, the site for the Austin City Hall is bordered on the south by Cesar Chavez, a primary east/west route through the city, and on the north by Second Street. The Colorado River is the most prominent boundary of the site. Located across Cesar Chavez to the south, it contains a large greenbelt area popular for Austin residents to hike, bike, picnic, and enjoy sponsored activities such as outdoor concerts and festivals. The site of the Austin City Hall reflects the positive aspects of choosing to develop an urban site—it allowed for the reuse of existing city infrastructure, including streets and utility lines. Parking for the building is located underground. Local native central Texas plants and trees are featured on the plaza and terrace levels of the south façade. The heavily treed plaza, sitting on top of the underground parking garage, helps control stormwater runoff, attracts native birds, provides shading from the south sun, reduces the heat island effect, and takes advantage of the southern breezes, while encouraging employees and citizens alike to utilize and enjoy the exterior living environment. Extraordinary detailing, angles, and cantilevers are a few of the building dynamics that help make this project intriguing as well as sustainable.
