The American Society of Heating, Refrigeration and Air-Conditioning Engineers, typically referred to as ASHRAE, released a technical resource regarding the reopening of schools and universities amidst the COVID-19 pandemic. They stated their position as, “Transmission of SARS-CoV-2 through the air is sufficiently likely that airborne exposure to the virus should be controlled. Changes to building operations, including the operation of heating, ventilating, and air-conditioning [HVAC] systems, can reduce airborne exposures.”
