But lately, living in more Earth-friendly and healthier house, turned into a mainstream and became affordable for most homeowners. Accordingly, the number of builders and remodelers who are offering their customers "green" option to build or improve their homes, is growing rapidly.
This year at the International Builders’ Show in Orlando, Fla., in February, the National Association of Home Builders unveiled its new “Certified Green Professional” designation. Contractors who want to earn this certification take part in the course “Green Building for Building Professionals,” where they learn principles to incorporate in their work that will result in homes that use less energy, conserve water and are all around more eco-friendly.
National Association of Home Builders (NAHB) developed three levels of green certification: Bronze, Silver and Gold - to make it more appealing to builders as well as their customers.
Homes earn points for various "green features" like sustainable building materials, efficient heating/cooling systems, site orientation, landscaping, energy and water efficient products with Energy Star ratings etc. More points means higher green rating.
