Thermal comfort in some naturally-ventilated lecture halls

Abstract

Environmental quality in lecture halls has a clear correlation with the performance of students. Through a comprehensive field survey lasting for more than 1 year, this study provides some insight into the environmental quality of the lecture halls. This study found that comfort temperature of most students was about 28.1 °C, 2 °C higher than that in air-conditioned buildings. The study also showed that in 29/40 surveys students were not satisfied with the indoor environmental quality (too hot or cold). The results of this study are the basis to propose design solutions to improving thermal comfort for students and to outline renovation plans of the existing lecture halls.
