In this study, a subjective experiment was conducted in a climatic chamber to investigate the effect of moderately hot environment on performance, fatigue, and especially the relationship between performance and fatigue. The climatic chamber was conditioned at operative temperature of 25°C (insulation value of 0.96clo), 28°C (insulation value of 0.96clo), and 28°C (insulation value of 0.61clo). Fourteen subjects were exposed in the environment for six hours. In this experiment subjects' performance at 28°C condition was lower than at 25°C condition, while they felt fatigue more strongly at 28°C condition than at 25°C condition. Besides, correlation between personal rates of complaints of fatigue and performance in z-score was observed with correlation coefficient of -0.72. From the linear regression model, increase in 10% of fatigue corresponded to the decrement in z-score by 0.083point.
