How Energy Efficient is Your City?

Over the last month, more than 3500 homeowners across the country have calculated their home’s energy profile using our new online energy audit tool.  And as we help homeowners through the process of learning about how efficient they are and how to most cost-effectively upgrade the efficiency of their homes, we’re starting to learn some really interesting things about the state of home energy efficiency in the U.S.

  • The average home that we’ve modeled has a 3-year savings potential of $2300 – meaning that each household could save that much money by making energy efficiency upgrades to their home.
  • Across the country, the average EnergySavvy score is a 63 out of 100, meaning that there’s a LOT of potential improvements to be made.

Some of the statistics for a few of our top cities:

City Average Year Built Average EnergySavvy Score
Boston, MA 1956 60
Chicago, IL 1965 61
New York, NY 1955 57
Philadelphia, PA 1961 56
Portland, OR 1977 65
San Francisco, CA 1963 76
San Jose, CA 1972 76
Seattle, WA 1977 63
Washington, DC 1976 61

So What Are We Learning?

It’s a little early for us to start drawing conclusions, but it’s interesting to note that the average age of homes in a metropolitan area doesn’t always correlate exactly with the average home efficiency in that city. Construction techniques, differences in local building codes over the years, and other factors can all impact overall energy efficiency for a city.

It’s also important to note that the impact of having a home with an EnergySavvy score of “50” in Seattle, WA (a city with a relatively mild climate) compared to a “50” in New York (a city with much colder winters and much warmer summers than Seattle) is significant in terms of the wasted energy and money.  Our online energy audit tool takes that into account, and also takes into account the big differences in the cost of energy from region to region, when predicting overall energy savings potential.
