“Average reductions of between 28% and 53%, with maximum reductions of between 31% and 84% in CO2 concentrations in different classrooms for similar seasons are observed.”
Structure
- Factor
- Carbon dioxide (CO₂)
- Setting
- classroom
- Study design
- comparison of indoor environmental quality in the classrooms of a learning building before the pandemic (2013) and after it (2021 and 2022): carbon dioxide, temperature and other parameters measured in the same rooms and seasons (class 4)
- Effect
- difference 53
- Caveat
- a before-and-after comparison across eight years, so the ventilation habits are not the only thing that changed
A Finding records what one published document states, verbatim and with its page. It is not a conclusion of Coridum; see the Claims that build on it.
