ASHRAE has announced that the following public review drafts are now available for review and comment online at osr.ashrae.org. Comments are due August 7, 2022.
- First Public Review of BSR/ASHRAE/IES Addendum bp to ANSI/ASHRAE/IES Standard 90.1-2019: Energy Standard for Buildings Except Low-Rise Residential Buildings: This addendum would remove a previous exception in the control requirements for captive key cards used in hotel guestrooms since this technology is not commonly used and is often bypassed.
- First Public Review of BSR/ASHRAE/IES Addendum cv to ANSI/ASHRAE/IES Standard 90.1-2019: Energy Standard for Buildings Except Low-Rise Residential Buildings: This addendum is in response to a revision to AHRI 920 (2020 edition + Addendum l) in which new metrics (ISMRE2 and ISCOP2) are being used to evaluate the efficiency of dehumidification and heating. The minimum efficiency requirements for 90.1 and DOE-covered DX-DOAS equipment have been modified for consistency with the new test procedure.
- First Public Review of BSR/ASHRAE/IES Addendum cw to ANSI/ASHRAE/IES Standard 90.1-2019: Energy Standard for Buildings Except Low-Rise Residential Buildings: This addendum proposes an additional lighting power allowance that can be used to achieve exit access stairway illuminance levels in accordance with the 2021 IBC.
