Webinar: ASHRAE 90.1

On March 6th 2024, the Federal Register published an article to publicly notify the U.S. Department of Energy (DOE) has reviewed and issued the determination that ANSI/ASHRAE/IES Standard 90.1-2022 will improve commercial building energy efficiency. The “DOE analysis indicates that buildings meeting Standard 90.1-2022, as compared with those meeting the previous 2019 edition, would result in a national average site energy savings of 9.8 percent of commercial building energy consumption…” However, many, if not most, Southwestern municipalities have adopted code IECC-2018 (Standard 90.1-2016) and IMC-2018 if not earlier code editions. The 2022 Standard edition has 89 amendments to the 2019 Standard plus another group of amendments brought forth in the 2019 version compared to the 2016 Standard still adopted by most “Authorities Having Jurisdiction”.



Varitec’s Director of High-Performance HVAC Solutions, Dan Hahne will present on:

The DOE’s Energy Savings Analysis report published in February 2024 that communicates the reasons for its “determination”
Identify the relationship between IECC and Standard 90.1 and list current code editions many Arizona Municipalities have adopted
Review purpose and scope of Standard 90.1-2022
Review the Standard’s Section 4 Compliance language and identify new design requirements defined by the Standard
Examine code language changes and additions compared to Standard 90.1-2016; i.e. building envelopes, heating, ventilating, and air conditioning systems, power,
Explore how Standard 90.1-2022 will impact HVAC designs by lowering thermal (sensible) energy loads and, consequently, building air flow rates.
Review Normative Appendix G and Appendix I: Performance Rating Method and other metrics in conjunction with Appendix G and, if time permits, other influencing appendices
