Understanding the phenomenon of Urban Heat Islands is crucial for the development of effective adaptation policies in urban areas. This study addresses the need for reliable simulation models to analyze thermal comfort in open spaces. The objective is to contribute to the temporal and spatial validation of urban microclimate CFD models. To achieve this, monitoring was conducted with a fixed reference station and a Low-Cost Portable Environmental Monitoring System (PLEMS) along walking routes in Curitiba during summer days (1); a CFD model was developed and simulated in the ENVI-met software (2); and statistical validation metrics of temporal and spatial model validation were analyzed (3). The results indicate that, although temporal validation shows high agreement with low magnitudes of error between simulated data and data measured by the fixed reference station, spatial validation demonstrates low accuracy of the CFD model in predicting thermal comfort in urban canyons. There are noticeable differences between intra-urban transect data and simulated data, requiring model calibration.References
