| Summary: | Indoor air quality (IAQ) is a term referring to the air quality within buildings and it relates to the
health and comfort of building occupants. Indoor air is becoming an increasingly more
concerning health hazard than outdoor air because people spend more time indoor. Ventilation
scenarios are important for indoor dilution of contamination. There are five investigated scenarios
involve in this study (ceiling fan plus air-conditioning, windows only, windows plus ceiling fan,
ceiling fan only and air-conditioning only). Six parameters investigated in each scenario consist
of the air exchange rates (ACH), less than 10 microns in diameter particle concentrations (PM10),
CO, CO2, relative humidity and temperature. Each scenario has different ACH and the indoor/
outdoor particles concentration ratio was calculated and its relation with ACH was determined.
The results of this study shows an expected increased of indoor/outdoor particles concentration
ratio in the investigated scenarios accordingly.
