Chicago Resources
Chicago Center for Green Technology 
Home to the City of Chicago's Department of the Environment, CCGT has knocked themselves out to become a comprehensive resource for builders and homeowners trying to find their way around the world of green building. The building itself was designed as a model of sustainable building practices and hosts a library of sustainable building materials; tours are available. The center hosts free seminars every week and their website offers a wealth of instruction and other references for both homeowners and professionals.
