Finding F-0468
“The carbon dioxide levels consistently exceeded the safe limit of 1000 ppm during all study sessions, with the time taken to exceed this threshold being directly proportional to the number of occupants.”
Structure
- Factor
- Carbon dioxide (CO₂)
- Population
- university students
- Setting
- classroom, LV
- Study design
- observational measurement over three days in two naturally ventilated classrooms of Rīga Stradiņš University: temperature, relative humidity and CO2 logged with an Aranet4 sensor during real study sessions with varying occupancy and window-opening periods (class 4)
- Caveat
- the 1000 ppm limit is the authors' reading of indoor air quality guidelines
