Easy solutions for indoor air problems at schools - Vallox

Carbon dioxide -based control is an excellent means to control ventilation automatically based on the need in premises where the number of occupants varies. The carbon dioxide -based control identifies when people enter the premises and enhances the efficiency of ventilation almost steplessly. This way, ventilation is not too efficient when there are only a few people present in the classroom but the …

CO2 Dashboards for Ventilation Monitoring in Schools

A simpler method could have been to put a CO2 sensor with a number display on the wall in the room, however there was a strong risk that this would be ignored or not seen due to its size. As the dashboard for the classroom was designed specifically to engage with children, it was felt that this risk would be significantly reduced. Another key advantage of the solution is that the CO2 data can ...
