To achieve the aim of gaining generalisable understandings for the best ways to occupy and operate schools safely in the light of possible COVID-19 infections, the research on this project was divided into 3 work packages:
Work Package Aim: We will conduct full-scale field measurements, and small-scale laboratory experiments on flows within schools, initially focused on classrooms. These will be supplemented by simulations of these buoyant turbulent airflows, and the aerosol transport within, for a range of indoor school environments.
Work Package Aim: Tools and techniques will be developed and deployed to quantify the risk of airborne spread within indoor spaces in schools based on usage, occupancy and ventilation. Scenario testing will be enabled that informs beneficial changes within schools, alongside informing design and retrofitting of spaces. We will work closely with the DfE, school building contractors, ventilation providers and school senior leaders to develop test scenarios and oversee the implementation of any chosen mitigation and monitor/report the effectiveness thereof.

DownloadWork Package Aim: Outputs will be developed so teachers and school leaders can assess the risks in their schools and take appropriate measures using a spreadsheet and online tools. Online and in room ‘traffic light’ warning systems will be developed reporting real-time and scenario-based risk. In addition, the new knowledge acquired (WP1&2) will be communicated to the DfE, school building contractors, ventilation providers and directly to school leaders at quarterly partner meetings and via a project website and social media.
