Check out The Greener Good: The Enviro-Active Museum as an example of sustainability focus in a public venue. As their Website states:

As environmental sustainability goes mainstream, many museums are finding they have an expanded role in educating on environmental issues; in turn, these museums realize benefits as they engage the public and attract support. Where once it was primarily science and children’s museums that made the public connection between interpretation and community action, now history and art museums and others, small and large, are finding that sustainability is an issue that connects their missions to local, regional and global communities in new ways.

Authors Sarah Brophy and Elizabeth Wylie are co-authors of a forthcoming book, The Green Museum: A Primer on Environmental Practice, due out this summer from AltaMira Press.
