Most of the construction waste also was recycled, and air-quality-friendly paints, adhesives, carpets, and flooring materials were used. Overall, the new ballpark is about 22 percent more energy efficient than a typical project of its size.
• Besides the Kansas City Royals, solar panels have been installed in the home stadiums of the World Champion St. Louis Cardinals, the San Francisco Giants, the Colorado Rockies, the Boston Red Sox, the Arizona Diamondbacks, and the Cleveland Indians.
• Working with the Natural Resources Defense Council’s Sports Greening Project, in 2011 the Cardinals undertook a “4 a Greener Game” program that included a comprehensive energy audit. It found nearly 200 energy-saving improvements to make at Busch Stadium. The facility already has diverted more than 2,400 tons of material from landfills over the past four seasons by increasing recycling and composting.
