Abstrakti

In this work, we investigated indoor air particle number concentrations and their size distributions in four office spaces in Europe. We used an Electrical low-pressure impactor (ELPI+) to enable high time-resolution, as well as a wide size range of particles (here 16 nm to 1 µm). In addition to indoor air concentrations, we report the concurrent outdoor concentrations and their relationship to one another. Infiltration factors ranged from 0.22 to 0.6 and the contribution of indoor sources was from 6 % to 51 %. Mechanically ventilated buildings had less infiltration. The number concentrations in two offices were always above the “low” threshold value given by the World Health Organization.
