SUMMARY:

Recent urban transformations have intensified microclimatic changes in cities, mainly due to increased building density, soil sealing, and the expansion of reflective materials on urban surfaces. These factors contribute to the urban heat island effect and raise outdoor thermal discomfort levels. In Brasília, such impacts become more critical during the dry season. This research investigates the relationship between urban surface materials, soil permeability, and microclimatic performance in two central areas of Brasília’s Plano Piloto: the South Commercial Sector (SCS) and the North Commercial Sector (SCN), which differ in their consolidation processes and urban morphology, leading to distinct thermal patterns. The methodology is based on the Local Climate Zones (LCZ) classification and three-dimensional simulations using ENVI-met v.5.7.1, considering real and prospective scenarios in Block 01 of the SCS (LCZ-2) and SCN (LCZ-1). The analysis focused on changes in Mean Radiant Temperature (Tmrt) and the Physiological Equivalent Temperature (PET) index. Results indicate that soil sealing produces the most negative effects, increasing both maximum and minimum Tmrt and PET values. Reflective façades showed an ambiguous response: they reduced minimum values at specific moments but significantly increased daytime peaks, intensifying thermal discomfort.
