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.
