Exerpt: How diseases are transmitted via HVAC, engineering controls, & ASHRAE's COVID--19


Managing HVAC Systems to Reduce Infectious Disease Transmission

This presentation begins by reviewing relevant information on airborne infectious disease transmission including disease transmission modes, infectious aerosol generation, and concepts of risk management. It then gives an overview of engineering controls including ventilation, filtration, and air disinfection and compares their advantages and limitations. Finally, ASHRAE's Covid-19 guidance is introduced and summarized.

Note: This presentation has quite a bit of COVID-specific content.
