SyracuseCoE Research Brief Series
We've calculated the number of COVID-19 infections that will be spread from a single COVID-19 "superspreader" to students and teachers in a classroom shared for 4 hours in different ventilation and masking conditions.

Appendix A of ANSI/ASHRAE Standard 62.1-2007, Ventilation for Acceptable Indoor Air Quality, describes the recycling of unvitiated ventilation air in a recirculating air-handling system. Equation A-2 considers air delivered through the primary air path (central air distribution system) and secondary air paths, such as fan-powered boxes or transfer-air fans. It contains a variable, Er, that describes the extent to which the secondary air comes from the zone in question, as opposed to coming from “average system return air.” This paper describes the development of an equation that can be used to quantify Er, and shows the results of the first …
