Abstract: Climate change has always been a global issue, and experts have predicted that it may worsen in the next few decades. Individuals spend most of their lives studying or working indoors. The quality of the indoor environment should be well-managed to ensure that occupants' health and well-being are taken care of. Some building owners are working towards a sustainable environment by consuming lesser energy. However, occupants’ thermal comfort level in the building may be neglected as owners would reduce the use of Air-Conditioning and Mechanical Ventilation (ACMV) and depend on natural ventilation. Occupants' dissatisfaction with thermal comfort would not only affect their health directly but also their work productivity and performance. Hence, this report focuses on the effect of Indoor Air Quality (IAQ) due to climate change and the impact of room features in an educational institution. Occupants often evaluate the IAQ based on three key parameters: Temperature, Relative Humidity (RH), and Carbon Dioxide (CO2). Using an IAQ sensor could allow data to be easily obtained and analyzed for monitoring. This paper aims to analyze and understand the relationships between the key parameters and the room features. The results of the readings will be compared between Holiday and School periods and between Dry and Wet seasons. The indoor air temperature and RH exceeded the acceptable limits, whereas the CO2 concentration is within the threshold range based on SS 554:2009. Occupants’ thermal comfort level may be overlooked due to inadequate fresh air supply and ventilation in some rooms. Besides, results have shown no significant differences between Holiday and School periods and between Dry and Wet seasons. However, the results may not apply to other schools as the SDE4 building is a Net-Zero Energy building and has implemented its own hybrid cooling systems.
