Effects of terraced classroom thermal environment on students' psychological sensations and concentration levels: Spatiotemporal analysis through measurements, CFD analysis, and questionnaire survey

The study examined the effects of the thermal environment in a terraced classroom on students' psychological sensations and concentration. The classroom thermal environment was continuously measured during 90-min lectures in May 2013. Students were asked to complete a questionnaire on their psychological sensations and concentration every 15 min during the lectures. Objective measurement data and subjective questionnaire data were analyzed. Results show that spatiotemporal heterogeneity of the classroom thermal environment was likely an important factor in students' psychological sensations and concentration.
