Abstract

The paper deals with the dependence of outdoor thermal comfort on street design with emphasis on summer conditions in hot and dry climate. The effects of the height-to-width ratio (H/W) and street orientation, the asymmetry of the vertical profile, the use of galleries, overhanging facades, as well as the use of rows of trees were investigated. The study was conducted by means of the three dimensional model ENVI-met, which simulates the microclimatic changes within urban environments in a high spatial and temporal resolution. Thermal comfort is assessed by means of the physiologically equivalent temperature PET. The results reveal that the vertical profile and orientation of the urban canyon have a decisive impact on the human thermal sensation at street level, as well as all other design details studied. This is mostly because affecting the sun exposure and so the heat gained by a human body. Shading appeared as the most important condition of comfort in the summertime, which can be reached by an appropriate combination of all those urban design describers.
