Designed by BNIM Architects, the OCSL embraces the concept of sustainable design and construction to the fullest. It is certified as a ?Living Building,? striving to have a net zero impact. Built in 2009, the center is an anchor for the groups' environmental efforts, and brings together state-of-the-art energy and waste systems, efforts to work with area farms and organic growers, and a teaching facility that demonstrates local solutions to global problems. It's unique location on one of the most important watersheds in the world?the 13,400-sq mile Hudson River watershed basin?informs its dedication to water quality and responsible stewardship.

Steve McDowell is an innovator, and his workplace is a laboratory for exploring ideas related to site, environment and technical investigation. He begins with the ?idea? as a cornerstone of process and believes in a lively exchange of thoughts to stimulate exploration and sustain innovation. These thoughts become a vehicle for discovery, and the result is research, such as the Packard Matrix, the first tool that measures the market costs associated with each level of LEED. Steve maintains that good design is about people?their health, productivity and lifting the human spirit through design. ILLUSTRATIONS: 100 colour photographs 30 ilustrations
