A calibrated thermal comfort index, which can represent human thermal sensation in a numerical way, is valuable tool for evaluating thermal conditions in urban areas. Brazil, a continental size country, presents eight different climate zones according to its bioclimatic zoning standar. Due to its area extension and climate diversity, thermal comfort indexes must be calibrates to each city to better represent the different thermal sensations of each local population. In Brazil, the Physiological Equivalent Temperature (PET) index, widely applied in outdoor evaluations, has already been calibrated for some cities, as: São Paulo (2008), Belo Horizonte (2010; 2016), Salvador (2010) and Curitiba (2012), by using different methodologies, during both data collection and statistical treatment stages. Considering the need to standardize the calibration methods, the aim os this work is to present the results of these calibrations, to compare them and to analyze the methodologies used in eac calibrations process, pointing out specific details of them. It is expected to come up with recommendations to forthcoming calibrations, making it possible to compare results and to facilitate future applications of the PET index as an evaluation tool for assessing thermal conditions in urban planning projects.
