Almost 100,000 new green homes have been built under model guidelines developed by the National Association of Home Builders. That’s up from slightly more than 60,000 that NAHB identified when it surveyed its members in 2004, the year it developed its guidelines. To NAHB, green building includes, among other factors, construction techniques that minimize waste and emphasize the use of sustainable materials.
