Healthy classrooms
Issue DateDec-2020
AbstractThis guide is intended as a tool to reduce the potential spread of the SARS-CoV-2 virus through aerosol transmission. Strategies and possible solutions for ventilation in classrooms are provided, alongside tools to evaluate the implemented ventilation strategies. • This guide has two parts. Part I focuses on how to maintain healthy indoor air in classrooms to reduce the risk of transmission of SARS-CoV-2 via aerosols, including ventilation and air cleaning, and how to check if the ventilation is sufficient to reduce risk using CO2 as a tracer. Part II focuses on simulations of risk of infection under different scenarios (tackled in Part I) in a classroom. • This guide is based on the Harvard University Guide (https://schools.forhealth.org) and other experimental studies on ventilation and filtration, as well as on modelling work by SCOEH (https://scoeh.ch). • The guide can be applied to other types of indoor spaces, such as offices or other public buildings, though some adjustments may be needed for physical characteristics (e.g. area and volume). • The use of masks, maintaining physical distance, and upholding hygiene measures, as recommended by governments and health experts, must be adhered to in conjunction with the strategies described here. • The measures described here aim to reduce the risk of contagion, but they do not eliminate the risk entirely.
