HERS Index

This Solargon 30-8 has a five star+ rating with a HERS index of 62 .  Similar to how MPG tells you the fuel efficiency of a vehicle, the HERS Index indicates the energy efficiency of a home. Each 1- point decrease in the HERS Index corresponds to a 1% reduction in energy consumption compared to a typical new home. (i.e. a HERS Reference Home with HERS Index of 100).Thus a home with a HERS Index of 90 is 10% more energy efficient than a typical home and a Solargon 30 with a HERS Index of 62 is 38% more energy efficient. The lower the number, the higher the savings for the home owner which equates to a lower cost of  ownership and higher resale value. This is a very good  score, and reflects the excellent performance of the design.
