This guide provides key information to policy makers on energy codes and standards and offers guidance on how policy makers can support the creation of statewide energy efficiency goals and standards. In addition, this guide instructs policy makers on how they can:

• Encourage the adoption of statewide codes.
• Establish energy code awareness programs.
• Support enforcement of and compliance with energy codes.
• Participate in the development of model codes and standards.
• Determine the viability of the new code.

This guide provides key information on energy codes tailored for architects and provides guidance on how they can support the adoption of new or updated energy codes and the resources needed to ensure compliance with what is adopted. The guide also includes information on the importance of architects in the development and compliance verification processes; information on the interface between codes and the design process; design and compliance tools; information on building construction and commissioning, and many other resources that are key to helping architects understand the important role energy codes through the design process play in addressing our energy, economic and environmental challenges.

This guide is designed to help state and local governments design and implement successful "beyond code" programs for new commercial and residential buildings. The goal is to help states and localities establish voluntary or mandatory programs that go well beyond traditional minimum code requirements for new buildings.

This guide provides information for anyone dealing with a lighting energy code or standard. It provides background and development information to help readers understand the basis for requirements and their intent. The guide also provides detailed explanations of the major types of requirements such that users can more effectively design to meet compliance while applying the most flexibility possible.

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.

To meet statutory requirements, DOE conducted an analysis to quantify the expected energy savings associated with Standard 90.1-2016. This report documents the methodology used to conduct the analysis. Based on the analysis, DOE has determined that the 2016 edition of the ANSI/ASHRAE/IES Standard 90.1 would improve overall energy efficiency in buildings subject to the code compared to the 2013 edition of Standard 90.1.

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.
