Green building programs are being launched all over the country as homebuyers look for ways to be energy-efficient and water-thrifty. Programs based on the National Association of Home Builders' Model Green Home Building Guidelines are going strong in St. Louis; Durham, N.C.; Albuquerque, N.M.; Dallas; Kansas City, Mo.; and Cleveland.

In August, the first statewide program based on these guidelines was launched - Green Built Michigan. Launches are also planned in suburban Philadelphia, Boston, central Arizona, Minneapolis-St. Paul, Las Vegas and the greater Baltimore area.
