Abstract
Human comfort is a complex feeling that is hard to be evaluated accurately. This could be affected by a variety of environmental factors and/or subjective events. This study investigated a special group of people’s specific comforts under certain circumstance. College students’ comforts under the conditions of various factors (thermal stress, noises, and psychological pressures) were investigated by field monitoring combining questionnaire. There were some important findings acquired. Initially, students’ neutral temperature (the temperature point that people are thermal free, indicated by operative temperature, Top) were 23.0 °C (males) and 24.1 °C (females); and their neutral acoustic pressures (indicated by A-weighted continuous sound pressure, LAeq) were 45 dBA (males) and 49 (females) dBA. In addition, under psychological circumstances, students were less heat-tolerable. This could be presented by lower neutral Top (less than 22 °C) at emotional stressed conditions. Nevertheless, their acoustic sensations were poorly affected by that. Students’ comforts were affected by environment qualities in physics and the test schedule. They were less comfortable as Top increase or getting closer to the test. Volunteers of the two genders were influenced differently, especially the acoustic environments. This study has developed a better understanding toward room occupants’ comforts in campuses.
