환기량과 노출시간이 생산성에 미치는 영향에 관한 연구

The previous studies indicated that the indoor environment condition affect on performance at rooms. But, it was uncertain whether subjects were exposed in enough time or not because the studies were conducted in 50~300min exposure time. So, the purpose of this study is to evaluate the increase in the subjects' performance with the ventilation change and exposure time. Three groups of 8 subjects were each exposed to an outdoor airflow of 5, 10 or 20L/s per person while other environmental variations were controlled. Also the subjects were exposed in 480min and performed 7 types of work such as addition, reaction, judgement. As a result, IAQ improvement increased performance with the ventilation. And performance increased highly when 150~330min exposure time but, the increasement of performance at the 480min exposure time is lower than those at 150~330min exposure time.
