项目摘要

The authors investigated the characteristics of the thermal environment created in an office by a partition-based TAC system, in which pressurized air is blown from the floor through outlets at the floor and near desks, and the effects of the TAC system on the thermal comfort and productivity of workers by monitoring the temperature and air current and conducting experiments including questionnaire surveys.In addition, the field measurement was conducted in a new office building of N Company which was designed as creative workplace which promotes communication between workers and encourages their creativity. Moreover, questionnaire based on SAP and work-simulated task, "Sudoku" and "Mind Map", was used to evaluate productivity in the office.In M Company, at the on and control conditions, using TAC, many workers declared "neutral" and "comfortable" to "slightly uncomfortable". At the control condition, the thermal sensation was neutral, and the percentage of people who felt uncomfortable was small. The scores were "comfortable" even at SET* values of 29 to 30℃, showing that the cool feeling of the subjects was enhanced by the TAC system. The ventilation experiment showed that fresh air could be efficiently supplied to workers by appropriately adjusting the direction of TAC outlets. Just little amounts of air from the floor outlets reached the respiration zone, little affecting the air in the respiration zone.In N Company, opening roller blinds changed light and thermal environment in "step workplace" which is one of the creative spaces. Desktop illuminance was above 800 lx in most points when roller blinds were opened. The research on workers' behavior showed the rate of seating time, staying time and walking time was about 50%, 40%, and 10% in the office. Therefore, not only working space but also other spaces such as "step workplace" can effect on workers' performance.

作者通过监测温度和气流，并进行问卷调查等实验，研究了基于分区的TAC系统（加压空气从地板通过地板和桌子附近的出风口吹出）在办公室产生的热环境特征，以及TAC系统对员工热舒适和工作效率的影响。此外，实地测量在N公司的新办公楼进行，该办公楼被设计为创意工作场所，促进员工之间的沟通，鼓励他们的创造力。此外，采用基于SAP和工作模拟任务“数独”和“思维导图”的调查问卷对办公室工作效率进行评估。在M公司，在使用TAC的控制和控制条件下，许多员工表示“中性”和“舒适”到“稍微不舒服”。在控制条件下，热感觉是中性的，感到不舒服的人的百分比很小。即使在SET*值为29 ~ 30℃时，得分仍为“舒适”，说明TAC系统增强了被试的凉爽感。通风实验表明，适当调整换气口的方向，可以有效地为工人提供新鲜空气。只有少量的空气从地板出口到达呼吸区，呼吸区的空气几乎没有受到影响。在N公司，打开卷帘改变了“阶梯工作场所”的光和热环境，这是一个创意空间。卷帘打开后，桌面照度大部分点在800lx以上。对员工行为的研究表明，在办公室，坐下时间、停留时间和步行时间的比例分别为50%、40%和10%。因此，不仅是工作空间，“阶梯工作场所”等其他空间也会影响员工的工作表现。
