Here are some highlights from the paper:

๐Ÿ‘‰ A method was tested to simultaneously monitor CO2ย concentrations in situ in multiple spaces of a building.
๐Ÿ‘‰ Operationalises CO2ย monitoring for use by building operators as an infection risk reduction tool.
๐Ÿ‘‰ Monitoring conducted in 1439 occupied rooms showed CO2ย concentration <โ€ฏ800โ€ฏppm in 1025 (72%) spaces, between 800โ€ฏppm and 1000โ€ฏppm in 267 (18%) and >โ€ฏ1000โ€ฏppm in 147 spaces (10โ€ฏ%).
๐Ÿ‘‰ In many cases assumptions that ventilation complied with relevant ventilation standards were incorrect.
