Abstract
During the COVID-19 pandemic, the importance of ventilation for ensuring occupants’ health was widely stressed, especially for densely occupied places such as schools (Ding et al, 2022). Correspondingly, new protocols of ventilation were implemented in school buildings among many countries and regions. In the Netherlands, school classrooms were first required to keep the windows and doors open, and later after a national lockdown more stringent measures such as reducing student occupancy were introduced. Previous studies have already shown that the ventilation in a large portion of school classrooms did not meet the requirement (National Ventilation Coordination Team, 2020). However, what are the actual effects of the COVID-19 measures on ventilation in school classrooms remains unclear.
This study aims to investigate 1) the ventilation sufficiency, and 2) the ventilation-related effects of temporary pandemic control and prevention measures in school classrooms under the COVID-19 pandemic.
