EarthTalk: Improving the energy efficiency of your home pays dividends now and later

Dear Earthtalk: I know that upgrading the energy efficiency of my home will make it less expensive to heat or cool, but will it also raise its market value significantly? — J.B.M., St. Louis, MO

That depends on your definition of “significant!” According to a study published in the Journal of Urban Economics, with every 10% increase in energy efficiency, a home’s market value increases by approximately 2.2 per cent. In another set of studies, the government-backed energy efficiency experts at Energy Star found that their certified homes in Maryland sold between 2012 to 2015 had a 2% to 5% sales price increase, simply because they were deemed energy efficient.
