Abstract
This study aims at investigating the gap between
perceived and calculated thermal comfort conditions in an educational building
for cooling and heating seasons. Within this context, thermal comfort
conditions and occupants’ satisfaction were investigated in four classrooms via
field measurements and questionnaires. Indoor environmental conditions were
obtained by field measurements and were used to calculate the predicted mean
vote (PMV) and the predicted percentage of dissatisfied (PPD) indices. Results
of simultaneously conducted surveys were used to calculate the actual mean vote
(AMV) as well as to assess occupants’ preferences and acceptability. ASHRAE
Standard 55-2013 and ISO 7730 were taken into account for evaluation. The
results show that perceived thermal comfort is greater than the calculated
thermal comfort for the cooling and heating seasons in the classrooms.

Abstract
Bu çalışma, bir eğitim
binasında algılanan ve hesaplanan ısıl konfor koşulları arasındaki farkı
soğutma ve ısıtma dönemleri için incelemeyi amaçlamaktadır. Bu kapsamda, ısıl
konfor koşulları ve kullanıcı memnuniyeti, dört derslikte gerçekleştirilen
deneysel ölçümler ve anket çalışması ile belirlenmiştir. İç ortam koşulları
yerinde yapılan ölçümler sonucu elde edilmiş ve ortalama tahmini oy (PMV) ve
memnuniyetsizlerin tahmini yüzdesi (PPD) değerlerinin hesaplanması için
kullanılmıştır. Eş zamanlı gerçekleştirilen anket sonuçları, gerçek ortalama oy
(AMV) değerlerinin hesaplanması yanında kullanıcı tercih ve kabul edilebilirlik
düzeylerini değerlendirmek için kullanılmıştır. Değerlendirmelerde ASHRAE
Standart 55-2013 ve ISO 7730 dikkate alınmıştır. Sonuç olarak, soğutma ve
ısıtma dönemlerinde algılanan ısıl konforun hesaplanan ısıl konfordan fazla
olduğu ortaya çıkmaktadır.
