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 freshair intake, levels of CO2 in the classroom can rise dramatically during the course of a classroom session.”. Brian W. Smith.

sensor. Impact of ASHRAE 62, then and now ASHRAE thru 2001. In the 1989 through 2001 versions of ventilation rates were based on either the number of occupants in the zone (cfm/person) or the floor area of the zone (cfm/ft²). As an example, let’s consider the ventilation rate for a lecture classroom with a design population of 65 (Figure 1). ASHRAE 621989 through 2001 required ...

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 ...

Why Monitor CO2 in Classrooms?

The most obvious method to ensure that a room is properly ventilated, which aids in maintaining a highlevel 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 …
