工作效率与室内环境质量密切相关，但如何评价办公室工作人员的工作效率一直是人机工程学研究的难题。在这项研究中，室内空气温度（17摄氏度，21摄氏度和28摄氏度）对生产力的影响进行了调查，有21名志愿者参加了实验室实验。受试者在实验室暴露期间进行计算机神经行为测试，还测量了他们的生理参数，包括心率变异性（HRV）和脑电图（EEG）。几个主观评分量表被用来挖掘参与者的情绪，幸福感，动机和任务所施加的工作量。结果发现，温暖的不适感对参与者的幸福感产生了负面影响，并增加了HRV的低频（LF）与高频（HF）的比值。在适度不舒适的环境中，任务所施加的工作量增加，参与者必须付出更多的努力来维持他们的表现，他们也有较低的工作动机。结果表明，高、低气温引起的热不适对办公室人员的生产力有负面影响，主观评定量表在评价IEQ对生产力的影响时可以作为神经行为绩效指标的有用补充。(C)2010爱思唯尔有限公司版权所有。
Productivity bears a close relationship to the indoor environmental quality (IEQ), but how to evaluate office worker's productivity remains to be a challenge for ergonomists. In this study, the effect of indoor air temperature (17 degrees C, 21 degrees C, and 28 degrees C) on productivity was investigated with 21 volunteered participants in the laboratory experiment. Participants performed computerized neurobehavioral tests during exposure in the lab; their physiological parameters including heart rate variation (HRV) and electroencephalograph (EEG) were also measured. Several subjective rating scales were used to tap participant's emotion, well-being, motivation and the workload imposed by tasks. It was found that the warm discomfort negatively affected participants' well-being and increased the ratio of low frequency (LF) to high frequency (HF) of HRV. In the moderately uncomfortable environment, the workload imposed by tasks increased and participants had to exert more effort to maintain their performance and they also had lower motivation to do work. The results indicate that thermal discomfort caused by high or low air temperature had negative influence on office workers' productivity and the subjective rating scales were useful supplements of neurobehavioral performance measures when evaluating the effects of IEQ on productivity.
