The 2015 International Energy Conservation Code (IECC) includes an Energy Rating Index compliance option. Increasingly, states and local code jurisdictions are adopting the 2015 IECC with the Energy Rating Index option.
RESNET and the ICC are implementing an educational effort directed at code officials on the HERS Index and the 2015 IECC Energy Rating Index option.
As part of this effort, RESNET and the ICC have developed a short video production aimed at code officials explaining the HERS Index and how it fits into energy codes.
