The research is based on result analysis of simulations of reference and prediction models of residential blocks in ENVI-met software. The reference model was designed according to the constructed residential block located in Nis. Predictive block models were considered, such as models with: green roofs, green facades, with increased ground greenery and a combined model with application of all above types of greenery. Another point that was considered was the median air temperatures and PET at 1.5 m height during the day across the entire residential block and selected measuring points within the block. The median air temperature of prediction models varies from the median temperature of the reference model by +0.11ºC to -0.23ºC at block level, while the PET of prediction models varies at block level from +0.91ºC to -4.2ºC, which leads to a change in category of thermal sensation and physiological stress. Due to different features of measuring points, the air temperature values and PET also differ. The largest difference in air temperature in relation to the reference model occurs at measuring point P2 in model with increased floor greenery and measures -0.91°C, while the largest difference in PET in relation to reference model occurs at measuring point P4 in model implementing all types of greenery and measures -18.45°C.
