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.

5. The New Central Library is replacing the John Henry Faulk Central Library as the new community oriented social hub of downtown
Austin. The design focused on creating maximum daylighting illumination and included a large rainwater collection system. The
building is the nation’s first LEED Platinum Certified library and a prime example of sustainable design.
The site of the New Central Library is a redeveloped brownfield. This involved excavating and properly disposing of approximately
30,000 cubic yards of contaminated soil and construction debris from the site prior to construction of the new library. The urban
site incorporates vegetative cover for approximately 33% of all open space and pre-development imperviousness has been
reduced by 36%.
The rainwater collection system eliminates the need for potable water in irrigation and bathrooms. The system is 85% efficient and
is expected to supply close to 813,500 gallons of water per year. On site captured grey water is used to meet irrigation demands
and a condensate collection system is used to meet demand for indoor potable water if sufficient rainwater is not collected.
The project also uses alternative energy sources to reduce greenhouse gas emissions. On site solar panels account for 8%, natural
gas accounts for 9%, and Austin Energy’s GreenChoice program that sources wind power, supplies the remainder of the facility’s
electricity needs. Energy efficient construction practices such as reduced demolition cost, diverted waste and recycling help reduce
greenhouse gas emissions. The construction process diverted approximately 93% of on-site generated waste away from landfills.
Additionally, the building ensures that 99% of regularly occupied spaces have access to views and 81% are illuminated by
daylighting. The library also connects to hike and bike trails on Shoal Creek and the nearby LadyBird Lake.

STRATEGIES:
This annual savings
is equivalent to:
On-site renewable energy through use of PV panels
reduces the amount of purchased electricity
Air conditioning systems use district supplied
chilled water cooling which is more efficient than
using an on site chiller
Decrease energy consumption through: demand
controlled ventilation, under-floor air delivery,
daylight harvesting, outdoor air economizer, etc.
