The National Wildlife Federation has put together documentation of years of sustainable projects on college campuses across the nation. Their website listed below, has a database of case studies starting back in 1997. It is a great resource to gather ideas for campus improvement, as well as raising awareness of the national sustainable community.

Thanks for the database website, it proved to have some value to my research.
