Over 40,000 people toured the home, which received 26 major environmental awards, including an international award in 1997 as the Top Environmental Project in North America. The ESH spawned an eight-part PBS television series titled “This New House” and a book titled “The Environment Comes Home”. A case study for this landmark project is available at the U.S. Department of Energy EERE Building Database -
