Finding F-1651
“In those 12 classrooms, on average we decreased mean CO2 with 491 ppm compared to baseline (sd = 324, range: -1085–124 ppm).”
Structure
- Factor
- Carbon dioxide (CO₂)
- Intervention
- Mechanical ventilation
- Setting
- classroom
- Study design
- ventilation intervention study in classrooms: mechanical ventilation set to a carbon dioxide threshold in twelve classrooms and the measured concentrations compared with the baseline week (class 2)
- Effect
- difference 491
- Caveat
- the range crosses zero, so in some classrooms the concentration rose
