The International Energy Conservation Code (IECC) prototype building models (prototype models) were developed by Pacific Northwest National Laboratory (PNNL), in support of DOE's Building Energy Codes Program (BECP), to simulate energy savings associated with changes in energy codes and standards. For residential buildings, PNNL utilized two base prototypes to simulate both Single-family detached house, and Multi-family low-rise apartment building types. Energy models for the recent versions of the IECC are available for each climate.

Pacific Northwest National Laboratory analyzed the relationship between the Residential Energy Services Network (RESNET) Home Energy Rating System (HERS) Index and the traditional simulation-based Performance Path used in the International Energy Conservation Code (IECC). The analysis evaluates, for a single-family residence with various characteristics, the ranges of HERS Index values that would imply compliance with the 2012 IECC Performance Path. Several building characteristics considered likely to result in quantifiable differences in the outcomes of the two approaches, or otherwise believed to be of interest to code developers and policy makers, are considered in the analysis.

This guide provides an aid that will make it easier to apply the heating, ventilation, and air conditioning (HVAC) control requirements found in building energy codes and addresses requirements defined by 2009 and 2012 editions of the International Energy Conservation Code (IECC) and ASHRAE Standard 90.1-2007 and ASHRAE Standard 90.1-2010.

This guide is a resource for understanding the air leakage requirements in the 2012 IECC and suggestions on how these measures can be met. It also provides information from Building America’s Air Sealing Guide, best Practices and case studies on homes that are currently meeting the provisions. The 2012 IECC and a few International Residential Code requirements are referenced throughout the guide.
