pedestrian thermal confort
Physiological equivalent temperature (PET)
Urban microclimate analyses are being used more and more to address the planning decision process to create livable and healthy public spaces. The study, conducted in collaboration with the municipality of Bilbao (Basque Country, Spain), presents a comparative analysis of green actions to improve outdoor thermal comfort conditions. The evaluation was performed in three typical urban street canyons characterized by different geometric proportions and five urban greenery scenarios in typical summer day conditions. For each scenario, the mean radiant temperature, relative humidity, air temperature, surface temperature and wind speed have been analyzed using ENVI-met model. The study quantitatively confirms that the vegetation elements such as grass, green roofs and trees, improves the thermal comfort at pedestrian level. Thermal comfort is assessed using the PET (Physiological Equivalent Temperature) thermal index. The highest PET reduction occurs by combining the presence of ...
