Finding F-0450
“There was a significant occupancy status main effect, with occupied spaces having higher average log CO2 (603 ppm) than unoccupied spaces (423 ppm), regardless of building zone (p < 0.001).”
Structure
- Factor
- Carbon dioxide (CO₂)
- Population
- university students and staff
- Setting
- campus building zones, occupied, US
- Study design
- pilot study on a college campus in Colorado: multi-zonal 48-hour measurements of particulate matter, formaldehyde, CO2 and nitrogen oxides in a LEED-certified, a retrofitted and a conventional building, occupied and unoccupied, mixed-effects models on log-transformed concentrations (class 4)
- Effect
- mean 603
- Averaging time
- 48-hour sampling periods
- Caveat
- printed as an average of log CO2 back-transformed to ppm
