The importance of the office environment to the comfort, productivity and health of workers cannot be overstated. While extant literature has shown that the physical environment of an office has a significant influence on how workers' perform their duties and on their comfort and health, few studies have explored the part played by the length of time they spend in the office. Using our dataset of 5149 workers from across the globe, we investigated the influence of time spent in the office building and at workstations on the relationship between Indoor Environment Quality (IEQ) and workers' productivity, comfort and health. An analysis of variance (ANOVA), Pearson's correlation and multiple regression analyses were employed. Our findings showed that while those who spent less time at work were less influenced by IEQ factors, noise and air quality were predominant in predicting how those who spent more time at work felt about their productivity, comfort and health. Specifically, a relationship did not exist between all of the IEQ factors and their perception of health for workers who spent less time in the office building. Also, the time spent in the office had a greater influence on the relationship between IEQ and workers' comfort than on their productivity and health. Our findings are useful for measures that ensure office workers achieve required work-related tasks under the appropriate working conditions. They give essential insights into the appropriate length of time workers should spend in the office.

办公环境对于工人的舒适度，生产率和健康状况的重要性不可低估。现有文献表明，办公室的物理环境对工人的工作方式，舒适度和健康状况有重大影响，但很少有研究探讨他们在办公室工作时间长短所起的作用。使用我们来自全球的5149名工人的数据集，我们调查了在办公楼和工作站上花费的时间对室内环境质量（IEQ）与工人的生产率，舒适度和健康之间的关系的影响。采用方差分析（ANOVA），Pearson相关性和多元回归分析。我们的研究结果表明，虽然那些花较少时间在工作上的人受到IEQ因素的影响较小，噪音和空气质量主要是预测那些花更多时间在工作上的人们对其生产率，舒适度和健康的感觉。具体而言，对于那些在办公楼里花费较少时间的工人来说，所有IEQ因素与他们对健康的看法之间并不存在联系。同样，在办公室里度过的时间对IEQ和工人舒适度之间的关系的影响要比对生产力和健康的影响更大。我们的发现对于确保上班族在适当的工作条件下完成所需的与工作有关的任务的措施很有用。他们对工人应该在办公室呆多长时间提供了重要的见解。IEQ的所有因素与他们在办公楼中花费较少时间的工人对健康的看法之间并不存在联系。同样，在办公室里度过的时间对IEQ和工人舒适度之间的关系的影响要比对生产力和健康的影响更大。我们的发现对于确保上班族在适当的工作条件下完成所需的与工作有关的任务的措施很有用。他们对工人应该在办公室呆多长时间提供了重要的见解。IEQ的所有因素与他们在办公楼中花费较少时间的工人对健康的看法之间并不存在联系。同样，在办公室里度过的时间对IEQ和工人舒适度之间的关系的影响要比对生产力和健康的影响更大。我们的发现对于确保上班族在适当的工作条件下完成所需的与工作有关的任务的措施很有用。他们对工人应该在办公室呆多长时间提供了重要的见解。我们的发现对于确保上班族在适当的工作条件下完成所需的与工作有关的任务的措施很有用。他们对工人应该在办公室呆多长时间提供了重要的见解。我们的发现对于确保上班族在适当的工作条件下完成所需的与工作有关的任务的措施很有用。他们对工人应该在办公室呆多长时间提供了重要的见解。
