The American Society of Heating, Refrigerating and Air-Conditioning Engineers is seeking comments on public review drafts of its 90.1-2022 energy standards, including addendum to previous drafts.
ASHRAE’s 90.1-2022 energy standards act as guideposts for sites and buildings, except low-rise residential buildings, and are used by a large number of municipalities as part, if not all, of their building code. Specific changes include clarifying on-site renewable energy and tax credit requirements, decreasing the maximum flow rate for shower heads, and adding credits for projects using performance rating systems for compliance.
An additional proposed addendum addresses single occupancy patient care spaces for behavioral health settings in hospitals, which it says includes the “the pressure relationship, ventilation, filtration, temperature, and humidity requirements for behavioral health multiple patient assembly areas.”
The 30-day public review on these addenda lasts until July 9. ASHRAE notes that all activity for reviewing and commenting on public review drafts can be completed online.
The society also announced adding a number of addenda, which have completed the public hearing process and are now available to download for free on their website.
Select examples of approved changes include representation of performance data for HVAC&R and other facility equipment, standard methods for measuring humidity and testing room air diffusion, and designations and safety classifications of refrigerants.
