Abstract
This study assessed the physical and chemical parameters related to indoor air quality (IAQ) in UNITEN and the IAQ of selected campus buildings were compared with guidelines provided by DOSH. A comparison of the IAQ of the selected buildings before and after the implementation of the Movement Control Order (MCO) were also conducted. This study is especially important as students spend most of their time indoors thus making them more vulnerable to exposure to indoor contaminants. Seven sampling locations around the UNITEN campus were selected which all have different structural layout. The indoor contaminants were recorded using real-time monitoring method and the parameters of interest are the Carbon Monoxide (CO), Particulate Matter (PM2.5 and PM10), Total Volatile Organic Compound (TVOC), relative humidity and temperature. Results show that the overall IAQ level in UNITEN is at a safe level as it is well below the DOSH permissible limit. Statistical analysis also shows that there was no significant difference in IAQ level between all sampling locations (P≤0.05). The comparison for Pre-MCO and Post-MCO also showed that there was no significant difference statistically which also mean that occupancy rate has little effect on the IAQ levels.
