  1. 1. WTP4 Administration Building 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. Water Treatment Plant 4 (WTP4) is Austin’s newest water treatment facility. The plant can treat more than 50 million gallons of water per day. With WTP4, Austin Water hopes to address rising problems of demand and reliability; a result of the growing population of Austin and the aging of water infrastructure. The LEED Gold Certified Administration building serves as the headquarters for the entire plant. The building contains the offices and conference rooms as well as the control room. The site design preserves 70% of the total site area by restoring its natural habitat through native planting. It also implements a stormwater management plan that protects stormwater channels from erosion. Water efficient landscaping using rotating stream sprinklers with pressure regulation reduce water consumption in the irrigation system. This allows for a 75% reduction in irrigation potable water use. In addition, the use of low flow fixtures in the lavatory results in a 41% reduction of indoor potable water. The building design claims to reduce energy cost by 48% and energy consumption by 46%. Strategies such as high efficiency glazing, reduced lighting power and water source heat pumps allow the building to be energy efficient. Additionally, the project uses wind energy, through Texas GreenChoice to power 100% of the facility’s electricity needs. Energy efficient construction practices such as reduced demolition cost, diverted waste and recycling help reduce green house gas emissions. The WTP4 Administration Building diverted close to 150 tons of landfill waste and 50% of the materials used to construct the building were recycled content. The project also aims to improve the indoor experience by using materials that emit lower levels of VOC’s and installing a CO2 monitoring system that provides feedback on ventilation performance. Additionally, the building ensures that 99% of regularly occupied spaces have access to views. With regards to transportation, the WTP4 Administration building has 7 bike storage spaces and 4 alternative transportation parking spaces available for the building occupants. The project is also located in an area that offers 12 neighborhood services within a half mile radius. The administration building boasts an innovative and energy efficient design that embraces an industrial aesthetic; the design responds not only to the function of keeping Austin’s water supply clean but also to the goal of keeping Austin’s environment clean.
