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.

This article describes an experiment that was carried out on an existing building to test the validity of the system ventilation efficiency equation for multiple-zone recirculating systems of ANSI/ASHRAE Standard 62.1. The system ventilation efficiency equation (SVEE) can be applied to buildings that use a recirculating air distribution system. It accounts for the fact that the return air carries some “unused” outdoor air, so that the amount of new outdoor air introduced at the air handler can be reduced. The SVEE is based on a mass balance but infiltration and interzonal mixing are not included in the formulation. Since infiltration …
