REQUIREMENTS EXPLAINED

Widely referenced in building codes and regulations, the ASHRAE 90.1 standard determines the minimum energy efficiency required for prerequisite compliance.

Required ASHRAE Standard 90.1 Version

The required efficiency increases for project registrations beginning in 2028, stepping up from ASHRAE 90.1-2019 standard to the more stringent ASHRAE 90.1-2022 standard. Compliance with the requirements of ASHRAE 90.1-2022 achieves a net average site energy savings of 14% compared to ASHRAE 90.1-2019, when including savings for prescriptively required renewable energy.

OPTION 1. ASHRAE 90.1-2019

Only projects registered before January 1, 2028, can use ASHRAE 90.1-2019 .

OPTION 2. ASHRAE 90.1-2022

Projects registered after January 1, 2028, must use ASHRAE 90.1-2022 .

Projects registered before January 1, 2028, can elect to use the 2022 version of the standard to earn points under EAc2: Enhanced Energy Efficiency .

For a summary of key changes to the ASHRAE 90.1 standard between the 2019 and 2022 publications, refer to ASHRAE 90.1-2022 Foreword and ASHRAE 90.1-2022, Informative Appendix M, Addenda Description.
