The effects of indoor environment quality on productivity were reviewed. It could be concluded that there was a need to systematically and quantitatively measure the effect of indoor environment quality on office worker's productivity. An experiment was carried out in field laboratory to investigate the effect of indoor air temperature (17 degrees C, 21 degrees C, and 28 degrees C) on productivity with 21 participants (6 females and 15 males). Participants' performance was evaluated with 13 computerized neurobehavioral tests, which assessed different neurobehavioral functions including visual perception, working memory, reasoning, executive functions etc. Participants' emotion was assessed with the Profile of Mood States (POMS), which consisted of six identifiable mood states: tension, depression, anger, vigor, fatigue, and confusion. Effort exerted on each neurobehavioral test was tapped with subjective questionnaires. The results revealed that more information could be provided when the subjective questionnaires were utilized together with the neurobehavioral performance measures. The POMS showed high reliability to investigate the relationship between thermal environment and occupant productivity. The performance of neurobehavioral tests decreased when the thermal environment deviated from neutral condition. Participants experienced more negative emotions and had to exert more effort to maintain their performance under moderately adverse (slightly warm or slightly cool) environmental conditions.
