In order to evaluate the thermal comfort conditions in the classroom, a field study was conducted in Sabzevar. Students' thermal sensations of class conditions were recorded at different hours of the day during the 2009-2010 academic year for different classes. At the same time, the temperature and humidity values of the classes were collected by a Data logger. To examine the differences, ANOVA, and Kruskal-Wallis methods were used. The results showed that the location of the classrooms in terms of geographical direction and building floor did not make a significant difference in the temperature and humidity, while the hourly differences of these parameters were significant.
In general, the responses related to the sensation of cooling had higher percentages than the state of heating (24% vs. 12%).
The thermal sensation in different months showed significant differences and the month of October had the lowest frequency in the feeling related to thermal comfort. In all months, except for October, the students' preferred was "heating". Although the performance of the heating system has been assessed as adequate, the operation time of this system should be done at a shorter distance from the start of morning classes to avoid wasting a significant portion of energy.
Although the temperature and humidity inside the classrooms did not show a significant monthly difference, but in terms of students' thermal sensation between different months, there was a statistically significant difference, therefore, the thermal sensation is something beyond physical characteristics (temperature and humidity) and In addition to being affected by climatic parameters, it is also strongly influenced by individual characteristics (sex, age, weight, height, clothing and activity level).
