I heard that the library in Ft. Smith Arkansas has a green roof though I haven't checked it out yet. On the green roof topic, this just came into my email.
The American Society of Landscape Architects Library and Education Advocacy Fund (ASLA Fund) will receive a $22,000 grant from the National Endowment for the Arts (NEA) for outreach and education programming surrounding the Society’s new green roof demonstration project.
The grant will fund an exhibit, a student workbook, and a discovery program to help raise awareness of how green roofs improve air and water quality, reduce the urban heat island effect, manage stormwater run-off, replace bio-habitat, and provide esthetic amenities to tenants and neighbors and economic benefits to developers and building owners.
“One of the main reasons ASLA decided to build a green roof on our headquarters was to show people what a green roof looks like and demonstrate the many environmental and economic benefits,” said Nancy C. Somerville, executive vice president/CEO of ASLA, who also serves as president of the ASLA Fund. "Not only will this grant enhance the experience for our green roof visitors, it will enable us to reach audiences of all ages across the country and around the world who may not be able to visit our project in person.”
