Abstract

The growth of cities interferes in the urban density and causes morphological changes that affect local microclimates. These changes in the urban space impact the thermal satisfaction of users regarding thermal comfort in outdoor areas. In open areas, "survey" studies can serve to define thermal comfort ranges, thereby calibrating existing thermal comfort indices. The present study defines a thermal comfort range for the Physiologically Equivalent Temperature index (PET) for a Cfa climate type (Pelotas – RS). The analyzed data were collected between July 2019 and March 2020. The measurements were carried out at five different spots of the city and with a samples of 1978 thermal perception votes collected during 53 monitoring campaigns. For recording climatic data, the TGD-400 equipment was used. The thermal comfort range for Pelotas has an upper limit of 23.3°C and a lower limit of 15.9°C, and thermal neutrality is reached at 19.6°C, all values in PET scale.
