Classroom thermal comfort in Klang, Selangor Darul Ehsan: A case study

High surrounding temperatures along with a packed number of occupants in a constrained premise such as a classroom are bound to bring about discomfort in the teaching and learning environment. This study measured classroom temperature changes in a Klang’s high school and examined some 140 of the school students’ perceived thermal sensation and comfort levels utilizing Predicted Mean Vote Model (PMV), Predicted Percentage Dissatistied Index (PPD), and questionnaire administration. Findings revealed that 52% of the students perceived their thermal comfort as between little and moderately warm. More male students (32% ) found themselves in comfort zone compared to their female counterparts (16%). In terms of time zone, the PMV was found to prevail and gendered only in the morning. Almost 75% of the respondents wanted a lower surrounding temperature. Additional initiatives are thus called for to moderate classroom surrounding temperature. Attention may also be paid to lower the number of students per classroom to help generate a more comfortable and conducive learning environment.
