The purpose of this work is to study numerically the indoorenvironmental conditions in an office. The indoor air quality status has already been studied experimentallyunder different indoor and outdoor conditions and it was found that indoor originated pollutants concentrations(CO2, PM10 and total VOCs) were elevated when smoking was taking place and the windows were kept closed. In order to investigate the mechanisms that affectthe indoor environmental conditions and the indoor chemistry the CFD model PHOENICS and the Multi chamber Indoor Air Quality model (MIAQ), were appliedbased on input data obtained during the experimentalcampaign. The indoor velocity, temperature and inert pollutant fields established indicated low wind speeds and a relatively non-uniform flow field due to the existence of obstacles. Finally, MIAQ results indicatethat deposition is an important factor that affects the indoor pollutants levels.
