Study of the indoor air quality in offices building (congrès EPIC 2002)

Résumé et principaux résultats

Congrès EPIC 2002 AIVC - 23/26 October 2002 :

The main objective of our study was to know more about indoor air quality in offices building over a long period. Our study has been carried out in one building located downtown Lyon (France). Measurements have been carried out one day each month during a one year period. Indoor air quality in the offices along with the one of air flows of the HVAC (Heating, Ventilating and Air Conditioning) installation (outdoor air, blown air and returned air) has been characterised by temperature and relative humidity of air, dust concentration level, air biocontamination and CO2 concentrations. Air flow from the fan coil units has been measured too. Air filters of the HVAC installation have been characterised in the field and in laboratory (fractional efficiency, pressure drop and mass of dust arrested by the filters). Our results show how the measured parameters have changed over the period and how the HVAC installation works. The HVAC installation of this offices building may be considered as a well working installation giving chance to the occupants to live in spaces where indoor air quality may be regarded as good.
