STANDARDS ACTIONS – 7/03/2026
30-day Public Review
July 3, 2026 – August 2, 2026

1st Public Review of BSR/ASHRAE/IES Addendum e to ANSI/ASHRAE/IES Standard 90.1-2025, Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings
This addendum modifies the purpose and scope of the Standard to allow for establishing requirements and setting criteria related to communication related to the use of energy and transfer of energy. These changes align the scope of ASHRAE 90.1 to allow for further reduction of energy use and improvement of energy efficiency of buildings and sites. Topics discussed during development of the changes to the purpose and scope included whether requirements related to energy sharing, use of biomass, stationary storage, transfer of energy, and EV charging should be included in 90.1. The proposed language is intended to be broad enough to allow for requirements to be developed for these topics.
