AT&T Park and the Giants received LEED Silver Certification for an existing building, one of the toughest category certifications to achieve under the latest rating system, for sustainability and efficiencies in the areas of human and environmental health, including sustainable sites; water efficiency; energy and atmosphere; materials and resources; indoor environmental quality; and innovation in operations. This differs from LEED certification that is granted to newly constructed ballparks.

"We are very proud to have helped AT&T Park become the first Major League Baseball park in the country to achieve LEED Silver Certification in the existing building operations and maintenance category," said The Linc Group President and CEO Tracy K. Price. "The Giants set this goal for themselves to better the environment, improve the ballpark, and enhance the fan experience. It's truly a great accomplishment."

• Measures implemented at AT&T Park to earn LEED Silver Certification included:
• Installing energy efficient compact fluorescent lighting throughout the ballpark;
• Becoming the first MLB ballpark, in partnership with PG&E, to install a solar energy system;
• Dramatically increasing waste diversion numbers, with 67 percent of the ballpark's waste being diverted from going to the landfill through an aggressive recycling and composting program;
• Enhancing Building Automation System controls;
• Automating lighting controls;
• Adding "green" concession stands -- Green Garlic Fries Stands;
• Installing ENERGY STAR-rated flat panel monitors throughout the facility;
• Implementing low-flush water closets, urinals, shower facilities, and aerators;
• Installing the Mitsubishi Electric Diamond Vision HD Scoreboard which is 78 percent more efficient than its predecessor;
• Re-commissioning the entire mechanical system;
• Implementing water conservation measures;
• Continuing to encourage fans to access one of the most transit friendly ballparks in the country by train, ferry, bus, bike or on foot.

"We congratulate the Giants for being awarded Silver LEED Certification for AT&T Park," said Greg Pruett, senior vice president of corporate affairs for PG&E. "Since the ballpark first opened in 2000, PG&E and the Giants have partnered to install the first solar panels in Major League Baseball, as well as energy efficient lights and concession stands. By adopting sustainable practices, the Giants are helping to shrink their carbon footprint and help fight global warming."

Created by the USGBC, the LEED program was designed to guide and distinguish high performance buildings that have less of an impact on the environment, are healthier for those who use the building and are more profitable than their environmental counterparts.

"Receiving LEED Silver Certification for an existing building is like winning the pennant. It's a huge accomplishment. We could not have accomplished this without our partners, Linc Facility Services, PG&E and Centerplate, as well as our vendors, Toro Irrigation, Waxie and Recology, employees and fans. However, this is an evergreen process, and we won't stop refining and reevaluating our sustainability and efficiency practices until we get to the Gold or Platinum level, or in other words, win the World Series," said Jorge Costa, senior vice president of ballpark operations.
