Part B: Joey Fox on Air Quality and Tools to Mitigate Airborne Illness

Layered prevention strategies in public congregate settings, using tools to assess risk, monitor, and clean air, are critical for future health.
The World Health Organization (WHO) recently released the Airborne Risk Indoor Assessment Tool(ARIA) and stated in the supporting publication " One of the learnings from this pandemic has been that we must reshape and redesign the building environment, while focusing on optimizing indoor ventilation and therefore, the air we breathe" (WHO 2024).
ASHRAE Standard 241, "Control of Infectious Aerosols", now provides requirements to clean the air. Using carbon dioxide monitoring “real time” as a surrogate to assess the quality of the air, will further indicate triggers and interventions required to clean the air.
We are also excited to have Joey Fox PEng, return. Joey is chair of the Ontario Society of Professional Engineers (OPSE), Indoor Air Quality Advisory Group. He will cover ensuring good indoor air quality, mitigating airborne diseases with ASHRAE 241 and use of UV.
