They asked students to participate over three different periods During each period, there were different carbonic levels in the room. Students had to take part in role-playing games on a computer: They were told they were managers and the organization they were running was having some problems....
The lower the CO2levels, the better your air. Because not all air is of the same quality, monitoring the air you breathe is vital to ensure it is clean and not stagnant. Studies have shown the less carbon dioxide (CO2) that is breathed in, the more alert people are and the less risk...
In this work it was aimed to assess ventilation conditions (carbon dioxide, CO2) and suspended particulate matter (PM2.5, PM10 and UFP) levels in 19 classrooms – including preschool, primary and secondary education – located in the metropolitan area of Ciudad Real, Central-Southern Spain, ...
"With the CO2measurements, high concentrations were found both inside classrooms and at rooftop exhaust vents when people were in the building," Buckley said. "CO2levels averaged above 1000 parts per million—the recommended limit—in classrooms and above 800ppm—high enough to increase growth in ...

We expect CO2 levels of 350 to 1,000 ppm in well ventilated indoor spaces. CO2 levels of 1,000 to 2,000 ppm are associated with complaints of drowsiness and poor air. While levels of 2,000 to 5,000 are associated with headaches, poor concentration, and loss of attention. ...
In this paper are presented the results of a monitoring campaign of the CO2 levels carried on in classrooms. The measures show the criticality of IAQ with values often much higher than the limits specified by standard, but also the possibility to act effectively with the manual ventilation ...
