Ventilation for Airborne Infection Risk Mitigation – What We’ve Learned from the Covid-19 Pandemic
Guidance for engineering controls to reduce exposure of building occupants to infectious aerosols has focused heavily on increasing outdoor air flow rates, upgrading filter efficiencies, and addition of standalone filtration and disinfection technologies. Less attention has been devoted to air distribution, however, there is a growing awareness of its significance. This presentation will consider a number of important ways in which well-conceived air distribution can enhance the effectiveness of a risk mitigation strategy and how future HVAC system designs may change as a result.
