ASHRAE Completes Draft of First-Ever Pathogen Mitigation Standard
05-06-2023 |
On May 15th, 2023 ASHRAE announced the completion of the first draft of its standard for maintaining healthy indoor air quality (IAQ), with final approval expected in June and publishing anticipated in July.
ASHRAE Standard 241P, Control of Infectious Aerosols provides minimum requirements for HVAC-related measures to reduce the risk of transmission of COVID-19, influenza, and other airborne viruses in homes, offices, schools, hospitals during periods of high risk. The standard offers guidance for creating healthier environments in the buildings where we work, live, and play.
The standard will address long-range transmission of infectious aerosols and provides minimum requirements for:
- Equivalent outdoor air (combined effect of ventilation, filtration, and air cleaning) for use during Infection Risk Mitigation Mode
- Room air distribution to reduce risk
- Characterization of filter and air cleaner effectiveness and safety
- Commissioning, including development and implementation of a Building Readiness Plan
- System operation in Infection Risk Mitigation Mode during periods of high risk
- Maintenance tasks and their minimum frequency
- Residences and health care facilities
