DOE has conducted an interim and limited update to its 2016 study to evaluate potential building code updates using the 2016 methodology and data. This interim update includes estimated savings resulting from more recent updates to the model energy codes, including the Standard 90.1-2016 and 2019 editions, as well as the 2018 and 2021 International Energy Conservation Code (IECC).

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 study investigates the technical feasibility of achieving zero energy (ZE) new residential and commercial buildings with national model energy codes. The approach and analysis are intended to provide guidance, inform goal setting, and direct future code development.

The Department of Energy’s (DOE’s) Building Technologies Office (BTO) recognizes the need to better understand the relationship between energy efficiency and resilience, including the need for standardized metrics, establishment of evaluation methods, and impact assessment for residential and commercial buildings. To address these needs, BTO commissioned three national research laboratories to develop a standardized methodology to quantitatively assess how energy-efficiency measures affect building thermal resilience. The study builds on previous BTO efforts to identify resilience metrics and outstanding analytical needs. It was completed under the guidance of a technical advisory group comprised of industry experts and representatives experienced in building resilience. This report summarizes the research effort conducted by Pacific Northwest National Laboratory, National Renewable Energy Laboratory, and Lawrence Berkeley National Laboratory, reports initial findings resulting from the efficiency- resilience valuation effort, and identifies areas of need for continued research and analysis.
