GREEN POINTS: Built on a brownfield site, the Nationals Park is the first Major League Baseball
stadium to receive LEED Silver certification from the Washington-based U.S. Green Building
Council. Efficient field lighting, a 6,300-square-foot (585-m2) green roof and recycling help
make the ballpark green. Millions of gallons of water will be saved each year through waterconserving
plumbing fixtures and air-cooled chillers. About 20 percent of the ballpark�s
construction used recycled materials and 5,500 tons (4990 metric tons) of construction waste
was diverted from landfills. Because the site is close to the Anacostia River, a water-filtration
system separates water used for cleaning the ballpark from rainwater falling on the ballpark.
Both sources are treated before being released to the sanitary and storm-water systems.
Special care also is given to screening organic debris, like peanut shells, from the storm-water
system. Signs around the park educate visitors about the stadium�s sustainable aspects.
