New Central Library- LEED Profile

  1. 1. New Central 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.

  5. 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.

  6. 6. NEW CENTRAL LIBRARY 710 W Cesar Chavez St, Austin, TX 78701 LEED PLATINUM 2018 REDUCES ENERGY CONSUMPTION 1 2 3 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. 3,013Metric tons of GHG emissions 325 Energy consumed by Per year Acres of forest3,549 Carbon sequestered by 297 Times Driving around Earth 36%REDUCTION ENERGY COST BROUGHT TO YOU BY THE OFFICE OF THE CITY ARCHITECT 39%REDUCTION ENERGY USE On-Site Renewable Energy (Solar): 245,156 kWh – 8% of Total Total Energy Use: 10,128 MMBTU Electricity Provided by Austin Energy: 2,438,703 kWh Natural Gas: 969,790 kBtu
  7. 7. Rainwater collection system eliminates the need for potable water in irrigation and in bathrooms. The collection efficiency is 85% On site captured grey water, such as roof water runoff, is used to reduce the irrigation demand Condensate drain collection system use to meet demand for potable water. System captures 90,000 gallons of water per year.
