The State of New Mexico has adopted a HERS Index Score option to the prescriptive path of the New Mexico Energy Conservation Code. The New Mexico Energy Conservation Code was amended to be based on the 2009 version of the International Conservation Code (IECC). The 2009 IECC was amended to allow HERS Index Score target as a option compliance path. The revised code specifies a HERS Index Score of 83 or less for climate zone 3 (southern portion of the state) and a HERS Index Score of 89 or less in other parts of the state. The regulation requires that the HERS Index Score must be confirmed by a certified RESNET home energy rater such as Go Green NM LLC.
The other significant change that the
State of New Mexico adopted was determining climate zones based on
altitude and not just the DOE latitude map. So New Mexico went from
having three Climate Zones (3-5) to having five (3-7)
The effort to adopt a HERS Index
Score compliance was led by the Santa Fe Area Home Builders
Association, Build Green New Mexico and the state’s home energy raters.
The State of New Mexico's action
demonstrates the growing momentum of code jurisdictions adopting the
HERS Index Score as a performance based code compliance option and the
growing number of local home builder associations supporting this
movement. Visit www.gogreennmllc.com for more information.
