| Summary: | A field study on the relationship between thermal comfort and students’ performance
was carried out in a technical school in Selangor. The buildings were mechanically
ventilated by fans. The measured environmental parameters were air temperature (ºC),
mean radiant temperature (ºC), relative humidity (%) and air velocity (m/s) of the
surrounding classroom area. The environmental factors were measured using Thermal
Comfort Equipment, which is capable to measure simultaneously all the environmental
factors. All the windows were left open for natural ventilation. Subjective measurements
were also conducted using survey questionnaire on the same days when the
environmental factors were measured. The Predicted Mean Vote (PMV) was calculated
using ASHRAE Thermal sensation scale which has been proposed earlier by Fanger
(1970) for the measured data. Further Predicted Percentage Dissatisfied (PPD) was used
to estimate the thermal comfort satisfaction of the occupant. The study revealed that
70% of the students’ population at the classroom is dissatisfied with the thermal
comfort. |
