- Abstract
This paper presents the results of outdoor thermal comfort research conducted in a public square of Campo Grande (hot-humid climate) during hot and cold seasons. The objective is to compare the predictive ability of the following indices: Physiological Equivalent Temperature (PET), Universal Thermal Climate Index (UTCI), Perceived Equivalent Temperature (TEP), Sense of Thermal Comfort (YDS), and Predicted Mean Vote (PMV). To obtain necessary data, micrometeorological measurements and questionnaire surveys were performed simultaneously during field campaigns. We found that a purely physiological approach was insufficient in the assessment, as the selected indices did not efficiently predict the thermal sensation votes of the locals. PET and UTCI had relatively satisfactory performances, but regional calibration was necessary. Acquired subjective votes enabled the proposal of PET calibration (comfort range 21-27 °C PET). Based on the adjusted thermal scale (63% accuracy), discomfort hours were estimated. Results provided by this study can help landscape architects and urban planners define specific design guidelines for urban open spaces of Campo Grande.
