Green roofs can improve air pollution, reduce fine particulate matter, and reduce storm water runoff. Additionally, flat green roofs reduce heating and cooling cost, thus reducing energy consumption.
George Washington University's School of Business is putting a flat green roof at the Elliott School of International Affairs City View Room Terrace this summer (2008). This news was reported in the GWSB newsletter.
GWSB M.B.A. student Brett Kaplan, helped secure funding for GW’s first-ever campus flat green roof. "This project is important to GW because it a major step forward in terms of enhancing the school’s sustainability profile. Aside from the environmental benefits, the green roof is designed to stand as a visual symbol of GW’s commitment to sustainability. The roof is meant to be a stepping stone for other green campus initiatives. If students, for instance, see that it’s possible to get this particular initiative passed, they will feel like their own campus greening ideas can also be brought to life, Kaplan said."
Not only is the building a commitment to sustainability, but it also will be used for educational purposes. The University is also going to use it as a show piece demonstrate its commitment to green technology and sustainability.
The 2,000 square foot roof is estimated to cost $25,000, 70% of which will be provided by the university. Grants and support from the student environmental association will provide the other 30%.
