| Summary: | This study was conducted to determine users' satisfaction with the building's indoor
environment. This study was performed at the main prayer hall of Pusat Islam
Engineering Campus, USM and the hostel room in Desasiswa Lembaran (SH2). It
involved determining whether the thermal comfort standards were being met, which
included the air temperature and relative humidity. The data were measured using
Temperature- Relative Humidity (T-Rh) Data Logger, and the result was downloaded
using T-Rh software. The Center for the Built Environment (CBE) Thermal Comfort
Tool is then used to input the parameters to calculate the Predicted Mean Value (PMV)
and Predicted Percentage Dissatisfied (PPD) for ASHRAE Standard-55. The parameters
inserted are air temperature, relative humidity, air velocity, metabolic rate and clothing
level. The PPD value shows the percentage of dissatisfaction. The PMV and PPD value
results were compared with the Industry Code of Practice (ICOP) 2010 standard limit.
The monitoring for this study was conducted for two sessions on a day, 1 P.M – 2 P.M.
and 5 P.M. -6 P.M. for both locations with minute intervals. The highest temperature
recorded in the mosque is 33.7°C, monitoring at 1 P.M -2 P.M. (Day 1). For monitoring
in the hostel room, the highest PMV and PPD values obtained were 1.6 and 57%,
respectively. Overall, the results indicate that most thermal comfort parameters measured
do not comply with the ICOP standard limit, whereby the PMV is not within the range
of -0.5 <PMV< +0.5 and PPD is >10%. This is due to poor façade design and inadequate
building ventilation systems. |
