Why Monitor CO2 in Classrooms? -

The most obvious method to ensure that a room is properly ventilated, which aids in maintaining a high-level of indoor air quality, is to monitor Carbon Dioxide (CO2) levels within the classroom. Every time you exhale, you release CO2 into the air. Therefore, the CO2 level lets you determine if the room is being properly ventilated with fresh outside air; thereby, helping you gauge the quality of the air within that …

Taking Effective Control of Ventilation

The simple addition of a CO2 speed controller to a classroom, or a humidity sensor to a changing room, can transform the energy consumption of the conditioned space in next to no time. The capital cost of such devices is low, and the return on investment is swift. The carbon footprint for delivering the solution is minimal, and the carbon saving, once implemented, is significant. These systems ...
