Structure

Factor: Carbon dioxide (CO₂)
Setting: hotel
Study design: indoor air quality audit of a hotel: carbon dioxide, comfort parameters and other indicators measured at defined sample points including guest rooms, against the national limit value (class 4)
Effect: other 1710
Caveat: the study says the level rises at night from the guests' own metabolism and that the air exchange rate proved insufficient

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.
