本研究的目的是调查和确定办公环境中居住者的热满意度与生理反应的关系，并通过人体生理信号来估计他们的热满意度水平。本研究以心率和7种局部体表温度作为生理信号，结合人因（性别、年龄、BMI），确定建立人因与生理信号相结合的热满意度预测模型。结果显示，总体热满意度水平与局部皮肤温度以及心率之间存在显著相关性。心率与总体热满意度呈负相关，前额、手臂、手腕（前后）、胸部和腹部的皮肤温度也与研究参与者的热满意度水平呈显著相关。该研究还通过对热满意度的影响确定了局部皮肤温度（以及性别和BMI）的顺序和优先级。考虑到所有人体生理因素和结果的实际应用，前额、手腕（背部）和性别的局部皮肤温度估计热满意度的准确率为88.52%，这为该程序的实际使用提供了重要的验证。
The purpose of this study is to investigate and determine the relationship between occupants’ thermal satisfaction and physiological responses in an office environment, and to estimate their thermal satisfaction level via human physiological signals. This study adapted the heart rate and seven local body skin temperatures as physiological signals, as well as human factors (gender, age, BMI), to determine establish a thermal satisfaction prediction model by combining human factors and physiological signals. The results revealed significant correlations between overall thermal satisfaction levels and local body skin temperatures, as well as heart rates. The heart rates showed a negative correlation with overall thermal satisfaction, and the skin temperature of the forehead, arm, wrist (back and front), chest, and belly also revealed a significant correlation with the thermal satisfaction levels of the study participants. This study also determined the order and priority of local skin temperatures (as well as gender and BMI) by their impact on thermal satisfaction. Considering all human physiological factors and practical application of the results, the local skin temperatures of the forehead, wrist (back), and gender demonstrated 88.52% accuracy for estimating thermal satisfaction, which provided significant validation for practical use of this procedure.
