This document summarizes research on CO2 levels and ventilation in a classroom. It presents data from CO2 sensors in the classroom over time, showing levels rising above recommended thresholds when windows are closed. Opening windows on the schoolyard side during recess lowered CO2 levels effectively. The data also showed a correlation between higher CO2 levels and more students falling asleep. Based on these findings, the researchers concluded that CO2 concentration is too high when windows are closed, potentially causing sleepiness in students. Their next steps are reducing CO2 using machines, studying relationships between CO2, weather and season, and completing their "Sensor Viewer" program.
