Energy efficient windows were the most commonly used green products, at 95 percent, followed by high efficiency HVAC systems at 92 percent. NAHB's data show that builders who always or almost always have their homes certified to a green standard use an average of 11.9 of the green products or practices listed, while builders who never or almost never have their homes certified still use 9.1 of them.
