DOE Webinar: How Building Codes Facilitate Resilient Communities
September 21, 2023

This report provides an assessment as to whether new buildings constructed to the commercial energy efficiency provisions of the 2021 IECC would save energy and energy costs as compared to the 2018 IECC. The Commercial Energy Efficiency chapter in the 2021 IECC allows users to either follow the provisions in the IECC or use Standard 90.1-2019 as an alternative compliance path. As such, PNNL also compared the energy performance of the 2021 IECC with the corresponding Standard 90.1-2019 to help states and local jurisdictions make informed decisions regarding model code adoption.

The purpose of this analysis is to examine the cost-effectiveness of the 2019 edition of ANSI/ASHRAE/IES2 Standard 90.1(ANSI/ASHRAE/IES 2019). PNNL analyzed the cost-effectiveness of changes in Standard 90.1-2019, compared to the previous 90.1-2016 edition, as applied in commercial buildings across the United States.  

This document provides recommendations for organizing effective and efficient submittal reviews of projects that follow ASHRAE 90.1 Section 11 and Appendix G.

This document outlines resources to help facilitate compliance documentation and submittal reviews.

The Submittal Reviewer is a professional responsible for reviewing the compliance documentation on behalf of the authority having jurisdiction or rating authority for projects following ASHRAE Standard 90.1 Section 11 and Appendix G. This document outlines the Submittal Reviewer responsibilities.

The Energy Modeler is a professional responsible for performing energy modeling and facilitating completion of the DOE/PNNL ASHRAE Standard 90.1 Performance Based Compliance Form on projects following ASHRAE Standard 90.1 Section 11 and Appendix G. This document outlines the Energy Modeler responsibilities.

This spreadsheet contains detailed end use data results from the Progress Indicator analysis of ASHRAE Standard 90.1-2013 conducted by PNNL.

This report considers the role of commercial building energy codes in enabling grid-interactive efficient buildings (GEBs). Specifically, it highlights the status of demand flexibility (DF) measures in ASHRAE Standard 90.1. It examines the model code-development process and identifies components preventing the consideration and inclusion of DF measures, including code scope, characterization and analysis of proposed new prescriptive measures, and the time-of-day and geographic differences in their benefits.

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 Standing Standards Project Committee (SSPC) for ASHRAE Standard 90.1 established a working group to develop an energy credits proposal.  The package of measures proposed for ASHRAE Standard 90.1-2022 includes 32 energy efficiency, renewable energy, and load management measures available. This technical document provides the general description of the proposed energy credit measures, the basis for calculation of potential energy credits, and the demonstration cost effective packages that justify the energy credit requirements by building type and climate zone.
