| Abstract |
This study explores the prediction of emotional responses in occupants within dynamic thermal environments, focusing on the influence of
their immediate thermal experiences. Using EEG responses, the research examines how these experiences affect the emotional states of
occupants. Data were collected from 13 male participants who underwent two heat experience scenarios (PMV 0 → PMV +2 and PMV -2
→ PMV +2), and both survey and EEG data were used for statistical analysis. The SAM responses revealed that even in similar non-neutral
high-temperature conditions, variations in immediate thermal experiences resulted in different emotional states among the occupants. Further
analysis of EEG responses showed statistically significant differences across the heat experience scenarios, particularly in relation to the
emotional dimensions of valence, arousal, and dominance. Notably, EEG responses in the dominance dimension were more sensitive than
those in valence and arousal. The RG indicator emerged as the most significant marker of changes in EEG responses linked to emotional
state. The findings suggest that EEG responses can potentially predict emotional states based on various thermal experiences, including prior
ones. Given that human physiological responses can quickly reflect transient changes in the thermal environment, this study offers valuable
insights for developing personalized thermal comfort models. |
