Abstract

This study was designed to comprehend the thermal comfort closely linked with stress through a brain wave (Electroencephalogram, EEG) and a salivary α-amylase response. On the experimental point of view, this study was conducted in a climate chamber based on PMV conditions. Seven environmental factors were set with the PMV scale from -3 to +3. Subjects' EEGs were measured in each condition for 65 minutes and the EEGs were measured on eight spots of the frontal lobe, the temporal lobe and the parietal lobe. All subjects' saliva samples were collected and a verbal report was done. As a result of analyzing the EEG reports, salivary alpha(α)-amylase response, and verbal vote, the EEG and salivary α-amylase response showed similar results. Among the seven PMV conditions the 0 to +2 conditions appeared to be relatively non-stressful compared to other conditions. On the other hand, the verbal vote showed that the -1 to +1 conditions of PMV are relatively non-stressful.
