Since 1995 HERS, Inc. has provided residential building systems consulting, training, inspections, and testing for energy efficiency in single-family homes and multi-family buildings in Arkansas and around the country.
A HERS Rating is very much like a car's MPG and is basically a score of the house's energy efficiency and estimated monthly utility costs. Both new and existing homes can have a HERS Rating performed. To have a house "rated" you need a certified HERS Rater who will review your house plans (or inspect and measure up an existing home), model the home with the energy features and performance test duct leakage and the home's tightness. Many municipalities currently require a HERS Rating to verify building code compliance.
