The National Park Service's Technical Preservation Services has issued new web-based guidance, Green Roofs on Historic Buildings, with information on green roofs and how they are constructed, special considerations for installations on historic structures, and guidance for meeting the Secretary's Standards for Rehabilitation. It is accessible from the 'Sustainability' section of the TPS website, but the direct link to the overview page is www.nps.gov/tps/sustainability/new-technology/green-roofs.htm.
