*The HERS^® Index is a scoring system established by the Residential Energy Services Network (RESNET^®) in which a home built to the specifications of the HERS Reference Home (based on the 2006 International Energy Conservation Code) scores a HERS Index of 100, while a net zero home scores a HERS index of zero. The lower a home's HERS Index, the more energy efficient it is in comparison to the HERS Reference Home. All energy cost and energy savings figures are approximate. The 20 year old home, 10 year old home, typical similar 2009 code built home and K. Hovnanian^® High Performance Home HERS Index ratings have been derived using an average of all home designs available at K. Hovnanian's^® Four Seasons at Beaumont, or similar home using local climate data. The HERS Index for the typical similar 2006 code build home is the benchmark for the HERS code. The HERS index of the Energy Star home is based on the compliance of EPA Energy Star New Homes Version 2.0 for the local climate zone defined as being that or below a HERS Index of 85.
