Washington D.C. has been know for storm water runoff issues and the city itself was sued by the Chesapeake Bay Foundation to meet EPA guidelines. This new green roof will do the following according to the press release:
- Hold up to .7 inches of rain to reduce stormwater runoff entering the sewage system and reduce streambank erosion.
- Shield the roof from the sun’s direct rays, which extends the roof’s life span, insulates the building during the summer and saves energy as well as mitigates urban “heat island” effects.
- Improve air quality by filtering the air that moves across the plants and, through photosynthesis, convert carbon dioxide into oxygen.
- Provide habitat for songbirds and pollinators.
- Reduce noise transfer from the outdoors.
- Provide a visually attractive sight for employees and visitors.
