Sick Classrooms Caused by Rising CO2 Levels

· Sick Classrooms Caused by Rising CO2 Levels. “Exposure to CO2 can result in drowsiness, eye irritation, and inability to concentrate. If a ventilation system provides inadequate fresh-air intake, levels of CO2 in the classroom can rise dramatically during the course of a classroom session.”. Brian W. Smith.

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 ...

7 Reasons Why You Should Measure CO2 Inside Buildings ...

· Many facility managers are increasingly turning towards monitoring CO2 for Demand Controlled Ventilation (DVC). Ventilation units can automatically set air intake on the assumption of maximum occupancy rate of a room, office or classroom. However, occupancy is often intermittent and unpredictable therefore leading to over-ventilation and energy inefficiencies. Monitoring CO2 levels …
