We would all like to be more efficient, whether it is at work, with our money, or with our time. We measure how fuel-efficient a car is by calculating the miles per gallon. To measure the energy efficiency of a house, builders and homeowners use a scale called the HERS index.
The HERS Index
The Home Energy Rating System (HERS) Index was developed by the Residential Energy Services Network to gauge hoe energy-efficient a new home is. The Hers Index applies specifically to new construction or down-to-the-foundation renovations of an existing home. To determine how energy-efficient your existing home is, you'll want to get an energy audit.
A standard new home earns a HERS Index score of 100. The majority of house scores fall between 0 and 150. The lower the number, the more energy efficient your home is.

So what can you expect from an energy audit? A HERS Rater assessment will look for air leaks in the building envelope, amount of leakage from HVAC ducts, the effectiveness of insulation inside walls and ceilings, the home's orientation/location, the number and type of windows, and the presence of solar panels or other energy generation methods.
Smart shoppers and people looking for a new home should ask about the HERS Index score. An efficient house is more comfortable, healthy, and costs less to operate. You can learn more at HERS Index Database.
