Pupils from St Teresa's Primary School, which is on the border of Carshalton and Wallington, recently came to Parliament to present to MPs and industry leaders their experiences of a new type of ventilation device during the pandemic. They relayed how various monitors throughout the school building would feed real-time CO2 levels into the a central system, allowing for better analysis and quicker interventions to remedy any causes for concern. The audience was made up of many senior figures from the engineering world, and the pupils more than held their own both when presenting and answering their questions!
