RESUMO

The researches about thermal comfort evaluation in Brazil, in the middle of 1930, were searching for the internationally used and proposed methods, so that the conditions to adapt them to Brazilian environmental parameters could be achieved. The work of two Brazilian researchers who were researching thermal comfort indexes by that time are known: Paulo Sá and Benjamim Alves Ribeiro. In their researches they were working to establish a relationship between the individual thermal sensation and the indexes obtained by the several methods used at that time, mainly the catatemperatures and the effective temperatures. When analyzing the research of Paulo Sá, it can be shown his scientific approach and the obtaining of comfort temperatures for the city of Rio de Janeiro, as well as the existent methodological and scientific difficulties. The values found by those authors were used to the calculation of the PMV, proposed by Ole Fanger, through the use of the software Comfort 2.02. This work also presents the methodology used by Paulo Sá and Benjamim Alves Ribeiro, Fanger and Michael Humphreys in researches accomplished at schools or with students. Fanger worked with students in acclimatized cameras and the others with naturally ventilated environments. Schools are an appropriate environment to studies about thermal comfort evaluation not only due to the importance of the theme, but also for the developed activity, age group and easiness of implementation of the research. A description and comparison of different methods applied to the school environment are presented in this work
