Another form of waste reduction is building houses that will endure for years before requiring any serious maintenance. Metal or cement-tile roofing, for example, will hold up much longer than standard shingles; many have life expectancies of half a century.No national standards
To help builders get a better handle on green building, the National Association of Home Builders has created its
Model Green Home Building Guidelines. "It's a resource guide for builders who want to figure out what green building is and learn about green building techniques," English says. The Guidelines can be downloaded from the website; it's also available in hard copy and on a CD-ROM through NAHB.
While NAHB's Guidelines provides a starting point, there's still no nationally recognized standard for green homes. Instead, there are about 70 regional groups across the country promoting green building in their own regions. They include Build It Green in Berkeley, Calif., and the Southface Energy Institute in Atlanta, which works with the Greater Atlanta Home Builders Association to educate builders. "We don't design and build green homes, but we train and provide technical assistance to those who do," says Dennis Creech, executive director at Southface, whose EarthCraft House program serves as a green benchmark for builders in the Southeast.
A national standard may be on its way, though. The U.S. Green Building Council, a non-profit group based in Washington, D.C., is currently testing its LEED for Homes pilot program in 12 different regions across the country. Jay Hall, acting manager of the program, hopes to "piggyback" with existing local groups such as Southface and have a national standard in place by late 2007. "We're trying to create a national standard for green homes, and send a clear message about what constitutes green as you go from one region of the country to the other," Hall says.
The USGBC also maintains a list of regional and local programs.
