This report is an outgrowth of the Green Building Roundtable of the U.S. Senate Committee on Environment and Public Works held in conjunction with the U.S. Green Building Council on April 24, 2002. The roundtable brought together diverse interests to educate members of Congress on green building trends and generated discussion about the economic and health benefits of green building, the barriers facing its progress, and the opportunities available to federal agencies to further promote sustainable spaces. These issues are described in the report. Sections of the report also address the role of green building in schools' environmental quality and offer recommendations to improve school environments.
