Taking into consideration that there is an expectation that the average temperature throughout Brazil remains between 3 ° C to 6 ° C higher in 2100 than in the end of century XX, this investigation analyzed the thermal comfort and the performance (through Reasoning Test Batch (BPR-5)) of students in the intelligent classrooms (news ICT – Information Communication Technologies) during three consecutive days - these classrooms have diverse sources of heat due to insertion of various technologies. The tests were performed at three levels of dry bulb temperature, respectively, 24°C, 20°C and 30°C (thermal comfort and discomfort), according to international standards. Through Generalized Linear Models (GLM) was established the relationship between the thermal variables and the performance of the students. Considering a comfortable situation, the ideal tg is 24.38°C and ta is 22.66°C. The measurements revealed that tg >> ta. Approximately 85% of the variation in performance of students can be explained through dry bulb temperature, globe temperature and relative air humidity. But an increase of 1 degree (between 20 and 30°C) in the globe temperature reduces the performance by 46%.
