The City of Santa Fe and Town of Taos, New Mexico have joined the ranks of other local governments that are requiring new homes to achieve a RESNET HERS Index target as part of the jurisdiction’s building code.
Since January 1, 2008 all new residential single family units built within the city of Santa Fe have been required to meet a confirmed RESNET HERS Index target. The Santa Fe Residential Green Building Code’s HERS Index threshold is driven by the size of the home. Homes that are 3,000 square feet or less must have a HERS Index of 70 or better. The required score goes down to a 0 HERS Index for homes greater than 10,000 square feet.

Santa Fe and Taos have joined communities from Colorado to New York that have incorporated the RESNET HERS Index into their energy code. The RESNET HERS Index is the industry standard by which a home’s energy efficiency is measured. The HERS or Home Energy Rating System was developed by RESNET and is the nationally recognized system for inspecting and calculating a home’s energy performance. Certified RESNET Home Energy Raters conduct inspections to verify a home’s energy performance and determine what improvements can be made to increase it.
