The effect of indoor environment may have an influence on the performance, productivity health and well-being of office workers.
Environmental factors such as indoor temperature and illumination have been investigated at three levels. A neurobehavioral test (NBT) has been proposed for the evaluation of office workersc performance. A field lab to emulate an office has been created. In controlled condition of environmental factors, the neurobehavioral test was conducted. The response time and the number of errors in each test have been recorded. A randomized block factorial design was used to analyze the responses of office worker's performance.
The results revealed that the independent and interaction effect of temperature and illumination have significant effect on the office workers' performance. The effect of indoor room temperature has more influences than the effect of illumination. The effect of indoor temperature has 38.56% of contribution on the performance. The optimum levels of indoor temperature at 21°C and illumination at 1000 lux have improved the work performance and health of office workers.
The indoor room temperature and illumination are more influence on the performance of the office workers. It may be concluded that the impact of indoor room temperature (38.56%) is more on the office worker's performance than the effect of illumination (19.91%). Further, it may be concluded that the optimum level of indoor room temperature (21°C) and illumination (1000lux) have improved the work performance, health and productivity of office workers.
室内环境的影响可能会对办公人员的工作表现、生产力、健康和幸福感产生影响。
研究了室内温度和照明等环境因素的三个水平。提出了一种神经行为测试（NBT）来评估办公人员的表现。创建了一个模拟办公室的现场实验室。在环境因素的受控条件下，进行了神经行为测试。记录了每个测试的响应时间和错误次数。采用随机区组因子设计分析了办公人员表现的反应。
结果表明，温度和光照的独立和交互作用对办公人员的表现有显著影响。室内室温的影响大于光照的影响。室内温度对性能的影响为 38.56%。室内温度为 21°C、光照为 1000 勒克斯的最佳水平提高了办公人员的工作表现和健康水平。
室内温度和光照对办公人员的表现影响更大。可以得出结论，室内温度（38.56%）对办公人员的表现影响大于光照（19.91%）。此外，可以得出结论，室内温度（21°C）和光照（1000lux）的最佳水平提高了办公人员的工作表现、健康和生产力。
