Nationals Park, Washington, USAWhat is the LEED Certification?
Nationals Park, the ballpark for the Washington Nationals of Major League Baseball, is situated in the southern part of Washington, along the Anacostia River and near the Navy Yard. Before its construction, RFK Stadium was home for the Washington Nationals. The first official MLB game (Nationals - Atlanta Braves: 3-2) was played on March 30, 2008. $ 611 million project was designed by Populous Devrouax & Purnell Architects and Planners. Construction of the stadium, the site of which was chosen by Mayor of Washington Anthony Williams, began in May 2006 and completed in 22 months. The stadium features 41,000 seats for fans, a 31m long scoreboard and suites on 3 levels, bearing the names of presidents Washington, Jefferson and Lincoln. The exterior facade is the embodiment of the city's architecture - an innovative design, made of glass and steel. Though the goal of the designers was announced a "certified" Green Project, finally it earned LEED Silver (higher level) certification. As the stadium is near the Anacostia River, the problem of rainwater treatment is of utmost importance. Before being pumped into the storm-drain system, it passes through the underground sand filters. Thanks to dual flush toilets and low-flow devices, water use is reduced by 15 % annually. The 585m2 green roof over the toilet area minimizes the roof heat gain. The stadium occupies approximately 102,200m2 and was built by Clark Construction and Smoot Construction.
