The effect of indoor temperature on occupants' attention abilities

실내 온도가 재실자의 주의집중력에 미치는 영향에 관한 연구

The purpose of this research is to investigate how the indoor temperature has influence on occupants' attention abilities as a basis of productivity. To achieve the purpose, the experiment in chamber was conducted. In the experiment, temperature was controlled according to two levels ($20^{\circ}C$ or $23^{\circ}C$) and other of factors were controlled uniformly. Subjects were exposed to those two different thermal environments. Each participant was asked to mark their answers on the state of attention measurement sheets (FAIR and Trail making test), in two conditions. Total 60 times of experiments were conducted. The main results are as follows. First, subjects showed the better attention abilities in relation to Q score at $20^{\circ}C$. But on the other hand attention abilities in relation to C score were better at $23^{\circ}C$. Second, subjects showed the better attention abilities in relation to concentrate on one task at $20^{\circ}C$.
