Evaluation of indoor environmental quality conditions in elementary schools׳ classrooms in the United Arab Emirates
This study presents findings of indoor environmental quality (IEQ) investigations conducted in elementary schools׳ classrooms in the United Arab Emirates (UAE). Average TVOC, CO2, O3, CO, and particle concentrations measured in the classrooms were 815 µg/m3, 1605 ppm, 0.05 ppm, 1.16 ppm, and 1730 µg...

| الملخص: | This study presents findings of indoor environmental quality (IEQ) investigations conducted in elementary schools׳ classrooms in the United Arab Emirates (UAE). Average TVOC, CO2, O3, CO, and particle concentrations measured in the classrooms were 815 µg/m3, 1605 ppm, 0.05 ppm, 1.16 ppm, and 1730 µg/m3, respectively. Whereas, local authority known as Dubai Municipality recommended 300 µg/m3, 800 ppm, 0.06 ppm, 9 ppm, and 150–300 µg/m3 for TVOC, CO2, O3, CO, and particle, respectively. Dubai Municipality recommended temperature and relative humidity (RH) levels of 22.5 °C to 25.5 °C and 30%–60%, respectively. Average temperature and RH levels measured in the classrooms were 24.5 °C and 40.4%, respectively. Average sound level in the classrooms was 24 dB greater than recommended sound level limit of 35 dB. Six (6) classrooms had average lux levels in the range of 400–800 lux. Two (2) classrooms had average lux levels in the range of 100–200 lux. The remaining classrooms had lux levels around the recommended 300 lux. High occupancy density was observed in majority of the studied classrooms. Observations during walkthrough investigations could be used to explain measured IEQ data. Poor IEQ conditions in the studied classrooms highlight the need for further research investigation to understand how poor classrooms׳ IEQ condition could influence students׳ health, comfort, attendance rate, and academic performance. |
