From the U.S. Green Building Council to the Audubon Society, environmental organizations are pushing out green building certifications faster than you can say “sustainable.” Most recently, the National Association of Home Builders submitted its National Green Building Standard for single-family homes, apartments and condos to the American National Standards Institute for approval, adding yet another term to the “must research list” for your next round of green renovations.

With so many organizations claiming authority on the matter, the deluge of details can get pretty confusing—and it’s especially true if you’re looking to build a new home. Which set of regulations is the best? Should you go with a LEED-certified home or a National Green Building Program home? It’s a lot of information to process.

Until the NAHB’s program is put into place, looking for a LEED-certified builder or architect may be the easiest way to go. The U.S. Green Building Council has a website, called the Green Homes Guide that contains great resources for home owners, including listings for builders and architects in your area that adhere to the LEED program.

Even if you’re only looking to remodel or update your home, the site is a good go-to spot for ideas. You can check out real-life residences in the process of going green, and read about small changes that can make a big difference.
