Basic Study on the Evaluation Method of Thermal Comfort by Cross Ventilation

Abstract

Natural ventilation has the effect on improving the comfort of the indoor environment. However, this effect has not been clarified since it is difficult to artificially reproduce the same airflow as natural cross ventilation. In this study, the psychological and physiological effects of fluctuating airflow on the human body in hot summer environment were evaluated. The subjective

Effects of various environmental grades on thermal comfort in semi‐outdoor spaces

“…Previous studies exist in which subject experiments that simulated natural wind with an artificial climate chamber showed the relationship between airflow and thermal comfort 30,31 ; however, hardly any studies are available that clarified the relationship between air velocity and thermal comfort in the semi-outdoor environment while considering the difference in "expectations for the environment" in spatial characteristics. In this study, we combined the tendencies in the "breeziness" evaluation of the elevations with the correlation between air velocity and the pleasantness/unpleasantness for analysis and showed that the difference in the "expectations for airflow" in spatial characteristics impacted the correlation between air velocity and thermal comfort.…”
