The American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) has issued a brief report on the best engineering interventions that can be used to minimize the spread of COVID-19 through the air. It also discusses how effective these interventions are likely to be.
The Society’s stated position on the transmission and control of the virus is that engineering controls should be implemented to reduce the viral droplets containing SARS-CoV-2 that travel through the air and cause COVID-19. ASHRAE also draws attention to the fact that their advice, which hinges on changing building operations, is not in conflict with the guidance offered by the United States Centers for Disease Control and Prevention (CDC) and the World Health Organisation (WHO). Neither the CDC nor WHO are able to explain all incidents of the community spread of the disease and both recommending using some engineering controls.
