Climate change and opportunistic pathogens (OPs) in the built environment

Pandemic experiences with manual ventilation and carbon dioxide (CO2) sensing in schools

This evidence review examines whether manual ventilation protocols are an effective means to improve school indoor air quality, and whether the use of CO2 sensors supports this endeavour. The review also considers whether manual ventilation causes thermal or acoustic discomfort, and provides an approach to developing a tailored ventilation protocol until ventilation retrofits can be completed.
