The aim of this work was to assess the influence of the ambient air quality and some indoorsources on the concentration levels of airborne fine particles and volatile organic compoundsin a large school of arts. Measurements were conducted, for both indoor and supply air, ineight office rooms in four floors controlled by four separate air handling units (AHU). Fineparticle measurements by SMPS in the size range 15-700 nm indicate that the placement ofthe HVAC air feed points and different AHUs affect the total particle concentration and sizedistribution in the supply air. Concentrations of VOCs were not affected by the air handlingunit. Instead, indoor VOC sources, such as paintwork classes, affected significantly theoffices VOC concentrations as well as indoor particle distributions. The location of officeswithin the school building and ventilation of offices affected indoor air quality attributes.
