The bad news: According to the California Energy Commission, heating and cooling ducts in an average California home leak almost 30 percent. Ouch!
The good news: A study of energy-efficient homes in The Appraisal Journal showed that every $1 reduction in annual energy bills resulted in a more than $10 increase in resale value. Ahh, better.
As we know, an energy-efficient home can increase comfort while reducing environmental impact and utility bills. Many home buyers take energy efficiency into consideration when home shopping, and may ask to see a seller’s utility records. But sometimes it’s hard to tell the difference between the house and the habits of the folks in the house. For example, what if the home’s current owner keeps the thermostat at 80 degrees all winter, whereas you keep it at 63 degrees and show off your sweater layering skills? How can you research the structure of the home itself, all by itself?
One answer to that question (there are many) is the Home Energy Rating System (HERS). Your HERS Whole-House Home Energy Rater will visit your home to examine the heating and cooling systems, test for air leaks, look for insulation gaps, measure appliance energy use, and so on. You’ll receive a detailed report about where the energy in your house is going, and where it could be conserved. You might use such a report for your own home improvement ambitions and enjoyment of your home, or you might share a HERS report with a prospective buyer, and stand out from other homes in your neighborhood. You can read a sample HERS report here.
Recently Ed Maeda, a fellow Realtor with Coldwell Banker DARE, was kind enough to film his home energy audit by HERS rater Craig Iden of Golden State Home Energy Consultants. (At the beginning of the clip, Ed mentions that it’s January 2007–but really this was filmed a couple of weeks ago in January 2011. Oops! Energy efficiency is exciting–it could happen to anyone!) You’ll see Craig explaining what he’s about to test at Ed’s house, then taking measurements, cranking up the blower door, etc. Click to view HERS Rating Walk & Talk in Davis, CA.
