Iowa is among the nation’s leaders in creating energy efficient homes. According to the EPA, there was a 21 percent increase in homes built to Energy Star standards from 2009 to 2010.

Often, the energy efficient measures taken to reach Energy Star guidelines include effective insulation, high-performance windows, tight seals and efficient heating and cooling systems.

Iowa was among sixteen states that had over 25 percent of its homes reach Energy Star certification in 2010. The other states were Arizona, Colorado, Delaware, Hawaii, Kentucky, Maryland, Nevada, New Jersey, New Mexico, Ohio, Oklahoma, Rhode Island, Texas, Utah, and Vermont.
