The EPA just announced that 25 percent of all single-family homes built nationally in 2010 earned EPA's ENERGY STAR. Since 1995 1.2 million new homes have earned that prestigious designation. According to the EPA that's about $350 million save on utility bills and about 450,000 vehicles worth of greenhouse gas emissions cut.
To earn the Energy Star, a home must meet strict energy-efficient standards, which include effective insulation systems, high-performance windows, quality construction to reduce leaks and drafts, efficient heating and cooling equipment and Energy Star qualified lighting and appliances. Sounds easy enough.
