Abstract

The main purpose of this study is to evaluate the current thermal conditions and dust concentration level of selected air-conditioned lecture rooms. The selected lecture rooms were lecture room of BK10, BK12, BK13 and BK17. These lecture rooms are located at Technology Campus, University Teknikal Malaysia Melaka (UTeM), Faculty of Mechanical Engineering. The main physical parameters involved in this project are air temperature (Ta), relative humidity (RH), air velocity (Va) and particulate matter of 10μm and 2.5μm. The measurement is taken by using Thermal Micro Climate and Dust Trak II. The thermal comfort analysis of this study is conducted through DeltaLog10 software. These include the analysis of Predicted Mean Vote (PMV) and Predicted Percentage Dissatisfied (PPD) index of measurements. A form of survey had been created and been separated to the occupant involved during the measurement for with occupant condition. According to the obtained results, almost 72% of air temperature measurement data is within the standard. Compared to relative humidity and air velocity, almost 67% of relative humidity and 86% air velocity readings were not satisfied the current standard. For the measurement of dust concentration, there were 100% readings of all particulate matter of 10μm measurement were satisfied the standard. On other hand, almost 90% of particulate matter readings of 2.5μm measurement were not satisfied the standard.
