EVALUASI KENYAMANAN TERMAL RUANG SEKOLAH SMA NEGERI DI KOTA PADANG
Abstract: This research
aims to determine
thermal conditions and
sensation of thermal
comfort in classrooms of high
schools in Padang. This study was conducted in 11 State Senior High School
(SMA) represented 11 districts in Padang. About 10% of total student body in
each schools were participated in this study to vote thermal comfort
questioners. To determine thermal
comfort level in
this study, PMV
(Predicted mean Vote)
and PPD (Predicted Percentage of dissatisfied) method
were used according to standard of thermal comfort in ASHRAE 55-2005 and ISO
7730. PMV method is used to determine scope of situation in the environment
that scaled from +3 for very hot until -3 for very cold, and PPD is a method to
calculate the number of human (in percentage) dissatisfied with the
environment. Calculated PMV and PPD
were compared with
PMV and PPD
resulted from individual
vote from questionnaires. Result
showed that in
general, thermal conditions
in classrooms had
air temperature and radiant temperature
from 27oC – 30oC, air humidity from 68% - 80%, and wind speed
of 0 m/s.
Calculated PMV from
this condition were
ranging from +1
slightly warm) until +2 (warm) while PPD calculated greater than 20%.
Compared with calculated PMV and PPD values, the individual vote showed values
from +0,5 (neutral) until +1 (slightly warm) while PPD values of individual
vote greater than 20% except for SMA 2 and SMA 11 Padang. It is concluded that
improvements of indoor thermal conditions have to make inside classrooms as
well as landscape
outside in order
to improve thermal
comfort level of students during learning and teaching.
