When Sustainable Industries talks about the "green monster," they are not talking about the famous left-field wall in Boston, however they still are talking sports (although Fenway scores tons of points with us due to its longevity). Sports stadiums are increasingly being green-built in an effort to negate some of the negative impacts the massive events cause. We've already talked about several attempts for green sporting from baseball and both the football played here in the States and football as the rest of the world knows it. However, a few more structures are in the works that could take sustainable stadiums to a whole new level. The new eco-friendly ballpark for the Washington Nationals, for example, could be the wave of the future. The stadium includes energy-efficient lighting, low-flow water features, and a 6300 square foot green roof that covers the concession area. But these green additions are small potatoes when it comes to the two truly revolutionary features of the ballpark.
For the 41,000 person stadium, the Nationals are setting aside less than 1300 parking spaces. A concerted effort with city planners will try to get folks to take the subway system to get to and from the games - negating what has to be the largest portion of carbon emissions, transportation to the game. The other cool feature is a water filtration system built directly underneath the stadium.
The system made of sand mimics wetlands by naturally filtering pollutants from the water. The filtration system also separates water used for cleaning the ballpark from rainwater that falls on the ballpark, treating both sources before releasing all the water to the sanitary and stormwater systems.
Now let's hope the Nationals baseball team can match the success of their new field.
