More than one year into the COVID-19 pandemic, IMEG engineers have found no evidence of the SARS-CoV-2 virus passing through a building’s HVAC system and infecting people in other spaces. A recent statement from ASHRAE concurs with this assessment.
“It is impossible to say for sure, but to date, we have found no evidence or study showing new cases being attributed to the air handling equipment, or evidence of long-range transmission through an AHU system,” said William Bahnfleth, chairman, ASHRAE Epidemic Task Force.
