At William Ryan Homes our new Zero Energy Ready Homes are built with state of the art, energy-saving materials and building systems to help save you money, conserve energy and provide your family with more comfort. The Home Energy Rating System (HERS) Index is the industry standard by which a home’s energy efficiency is measured. The lower the HERS Index score, the lower your energy costs.
The reference home is HERS Index = 100 (2006 IECC, TX new homes built pre 2012).
A home with a HERS Index Score of 70 is 30% more energy efficient than the reference home (Typical of some new builds in TX)
A home with a HERS Index Score of 130 is 30% less energy efficient than a standard new home (Typical existing neighborhoods)
The HERS Index is now used as a universal compliance pathway for the State of Texas’ energy code (HB 3215)
Greatly reduces thermal gaps in exterior walls and roof, sealing your home against heat, water and insects
