Abstract: In this study, energy and exergy analysis of the human body are performed for summer and winter seasons for Bhopal (India). The outcome of this work indicates that the energetic metabolic rate is much higher than the exergetic metabolic rate. The maximum energy loss from all sources is computed as 34.26 W/m² in summer and 40.48 W/m² in winter. Further in the summer season, the predicted mean vote (PMV) value is 0.85, and in winter, this value is 1.06. The predicted percentage dissatisfaction (PPD) for summer and winter are 24.49% and 28.71%, respectively.

Keywords: energy; exergy; predicted mean vote; PMV; predicted percentage dissatisfaction; PPD; thermal comfort; summer; winter.
