CLASSROOMS INDOOR AIR QUALITY COMFORT PARAMETERS AND OUTDOOR PARTICULATE MATTER INFLUENCE OVER INDOOR CONCENTRATION LEVELS IN ROMANIAN SCHOOLS

Andrea Brigita Blaga

Abstract :

This experimental study presents new data on indoor comfort parameters and PM evolution over a school day. Results showed that comfort parameters did not meet recommended levels during teaching activities and an increase of PM concentrations from the beginning until the end of classes. Correlations between indoor/outdoor/PM concentrations and the ventilation rate showed that the main PM source was in the classrooms. I/O ratios demonstrated that the concentration of indoor pollutants was not necessarily influenced by outdoor sources, the poor ventilation determining the existing but low influence of outdoor concentrations.
