Benefits and Well-Being Perceived by Pedestrian in Vegetated Urban Space in Periods of Heat Stress

Abstract—This research aims to study and analyze the effect of the urban vegetation on microclimate and thermal comfort in external spaces. The experimental method used calls upon the techniques of observation and site measurements. A case study of an external space located in the city center of Constantine (Algeria), characterized by Mediterranean climate, hot and dry. The results confirm the role of the quantity of shade by the vegetation on human comfort, a positive correlation between the air temperature, mean radiant temperature (Tmrt), and physiologically equivalent temperature (PET) in hot seasons. Vegetated urban space influences the quality of perception, the creation of urban ambience and improves pedestrian’s thermal comfort and use of outdoor areas for this type of climate.
