This report explains the methodology used to develop version 4.6.5 of the REScheck software in order to support compliance determination for IECC editions 2009, 2012, 2015, and 2018.

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 report provides an assessment as to whether new buildings constructed to the commercial energy efficiency provisions of the 2015 IECC would save energy and energy costs as compared to the 2012 IECC. PNNL also compared the energy performance of the 2015 IECC with the corresponding Standard 90.1-2013. The purpose of this analysis is to help states and local jurisdictions make informed decisions regarding model code adoption.

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.

The most recent edition, the 2018 IECC, was published in August 2017, triggering the DOE review and determination process. In response, DOE and Pacific Northwest National Laboratory (PNNL) conducted a preliminary analysis to determine energy savings for the 2018 IECC residential provisions relative to the previous edition--the 2015 IECC. This report documents the methodology used to conduct the analysis and summarizes the results and findings.

The commercial IECC prototype building models were developed by Pacific Northwest National Laboratory in support of the U.S. Department of Energy's (DOE's) Building Energy Codes Program. These prototype buildings were derived from DOE's Commercial Reference Building Models. This suite of commercial IECC prototype buildings covers all the Reference Building types except supermarket, and also adds a new building prototype representing high-rise apartment buildings. The prototype models include 16 building types in 17 climate locations for the 2006 IECC, 2009 IECC, 2012 IECC, and 2015 IECC. This combination leads to a set of 1088 building models (in EnergyPlus Version 8.0). Also included is a scorecard for each prototype building. The scorecard is a spreadsheet that summarizes the building descriptions, thermal zone internal loads, schedules and other key modeling input information.
