The study investigated the IEQ effects on learning performance by means of field survery, and the target group was late-teen students. The field experiments were carried out at two technical colleges in Japan. At each college, a ordinary use classroom was adoped for the experiment. In order to evaluate the effects of indoor temperature and outdoor air supply rate, air conditioning units and ventilation fans were controlled at 3 levels (22,25,28 °C;5,10, 20 m3/s/person) and 5 combinations of them were adopted as the experimental cases. In every cases, the leaning performance was evaluated with a 30-minute examination after a 180-minute video mage lecuture. The results showed that the examination score decreased in the case of low temperature or low outdoor air supply rate. However, the examination score was not changed in the case of high temperature, which might be caused by seasonal effect. According to comparisons with previous studies, the learning performance of late-teen people was considered to be less affected by indoor environment than that of older people, if their background knowledge of the learning subjects was eqivalent to the older people.
