The below draft is scheduled for a 30-day public review from March 29 to April 28

  • BSR/ASHRAE/IES Addendum w to ANSI/ASHRAE/IES Standard 90.1-2022, Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings (first public review draft).

This addendum proposes a reduction in the decorative lighting allowance to reflect current LED technology and practices.  More efficient lighting sources allow for a lower allowance. The decorative lighting allowance was first included in the 1999 Standard and was 1.0 W/ft 2. The value was reduced in 2016 to 0.75 W/ft2; and in 2022 to 0.7 W/ft2. This addendum proposes a fixed value of 0.50 W/ft2 for all spaces. Because this is an optional allowance in the standard, a cost-effectiveness analysis was not required for this addendum.
