This paper presents on the results of field test on academic performance in classroom. In particular, this paper reports the effects of thermal environment on motivation and productivity for student in actual classroom. In order to evaluate the consistency between field test and realistic simulation experiments which previously reported (part 9 and part 10), the same evaluation method were adopted. When thermal environment changed, productivity in classroom is improved by 9.8% on average (n.s.) and motivation in classroom is varied according to thermal environment (n.s.).
