What is the school CO₂ analysis, and how does it work?
Open Analyses > School CO₂.
It documents CO₂ while classrooms are in use. Choose Danish school practice, FoHMFS 2014:18 (Sweden), UBA / ASR A3.6 (Germany), EN 16798-1, or Belgian IAQ level A/B.
Under the German set, below 1000 ppm is acceptable, 1000–2000 ppm is a warning, and above 2000 ppm is unacceptable. The Danish set treats 1000 ppm as the limit during occupied hours. EN 16798-1 scores classrooms as ppm above outdoor air. Only occupied time is scored, from the raw readings. A gap longer than 20 minutes breaks a run and is not counted as acceptable.
- Choose the rule and the period (7 days, 1 month, this quarter, this school year, last school year, or your own dates).
- Set the occupied hours. The default school pattern is Monday to Friday, 08:00–16:00.
- The PDF includes minutes observed, minutes over the limit, the peak, a table per room, a calendar of daily peaks, and charts for the worst rooms. The AI note is guidance only.
