Abstract

It is difficult to evaluate the effect of indoor environmental quality on productivity by measuring only task performance. In this study, the monitoring of cerebral blood flow during task by Near Infrared Spectroscopy is introduced as one of the objective evaluation methods of workers' human response that are factors affecting task performance. The results of three subjective experiments showed that monitoring cerebral blood flow can be applied to evaluation of mental demand level they need to do tasks. The higher mental demand was required, the more the left side of Atotal hemoglobin concentration became. The results of the subjective experiments in moderately hot environment show that the mental demand level to maintain their task performance was higher in hotter environment than that in thermal neutral environment.
