Indoor air quality of naturally ventilated Croatian classrooms

Indoor air quality in schools has been a public concern for a number of years, as adverse effects of poor air quality have far-reaching effects on children’s and student’s heath. The present work aims to evaluate the effect of manual airing on indoor air quality in two naturally ventilated Croatian schools. Indoor air quality was studied in terms CO2, air exchange rate and ventilation rate during the heating and non-heating seasons and compared with outdoor levels. Closed windows over a prolonged period of time, result in alarmingly high CO2 concentrations (up to 4000 ppm), and consequently, poor ventilation rates. Longer windows opening periods reduce indoor CO2 but simultaneously increase the outdoor-generated sub-micron particles.
