Title: A Preliminary Feasibility Assessment of the RESNET HERS Index as an Alternative Compliance Path for the IECC

This analysis provides a limited evaluation of the relationship between the Residential Energy Services Network (RESNET) Home Energy Rating System (HERS) Index and the simulation-based performance approach used in the 2012 International Energy Conservation Code (IECC). Not all differences between the approaches are analyzed here; only a few distinctions considered likely to result in quantifiable differences in the outcomes of the two approaches and for which available studies have not quantified those differences. This analysis establishes, for a single-family residence with gas heat and a crawlspace foundation, a set of climate-zone-specific, complying HERS Index values that could be used to inform the development of a HERS-based compliance path in the IECC.
