ASHRAE guidelines and standards open for comment

The below draft is open for a 30-day public review 

• BSR/ASHRAE Standard 241P, Control of Infectious Aerosols (full public review). Commenting is open Jan. 31 to March 2.

  The purpose of this standard is to establish minimum requirements for control of infectious aerosols to reduce risk of disease transmission in the occupiable space in new buildings, existing buildings, and major renovations to existing buildings, including requirements for both outdoor air system and air cleaning system design, installation, commissioning, operation, and maintenance. This standard defines the amount of equivalent clean airflow necessary to substantially reduce the risk of disease transmission during infection risk management mode.

The below draft is open for a 45-day public review 

• BSR/ASHRAE/ASHE Addendum s to ANSI/ASHRAE/ASHE Standard 170-2021, Ventilation of Health Care Facilities (second public review). Commenting is open Feb. 14 to March 31. 

  Proposed addendum s revises portions of Sections 7 and 8 to provide clarity of intent and/or correlate elements (indicated below) of the current standard. Addendum s also follows the continuing maintenance process in further coordination with the Facility Guidelines Institute infection preventionist team and 170 committee to result in a coordinated document for use by all stakeholders in the health care community. 

  This proposed addendum consists of the following general edits: add footnotes to examination type spaces in table 7-1, 8-1, and 8-2 regarding patients with undiagnosed gastrointestinal symptoms, undiagnosed respiratory symptoms, or undiagnosed skin symptoms.
