This paper (Part 2) reports on the realistic simulation experiment using climate chamber, focusing on varying air change rate as in the field test, and the consistency of the climate chamber experiment and the field test. Physical environment and academic performance evaluation methods of the climate chamber experiment are quite the same as those of the field test. In the result of the climate chamber experiment, correlation analyses show that lower air change rates link to reduced academic performance (R^2=0.74, p=0.03). In this study, the consistency of the climate chamber experiment and the field test was confirmed. Therefore, when the result of the test and the climate chamber experiment is used, the correlation analysis shows that there is a correlation between the academic performance and air change rate (R^2=0.82, p=0.002).
