Indoor air quality in two different office buildings: Part 2: Indoor and outdoor airborne particulate levels and air filtration - Communication au Congrès Healthy Buildings 2003

Résumé et principaux résultats

The study has been carried out in two different French buildings. The main objective of the study was to know more about office buildings' indoor air quality as well as HVAC installation working over a long period (1 year). A lot of data are available but this paper focuses on the relationship between air filtration of the air handling units and indoor airborne particulate levels measured both in the offices and within the ducts of the air handling systems (outdoor air, blown air). The results of the study show how the fractional efficiency of the filters has changed along time. The air blown in the offices by the air handling systems is well filtered and reduces significantly the amount of particulates entering the buildings. The need of good air filtration for better indoor air quality has been shown.
