Rapid urbanisation puts pressure on urban planning to create layouts that are sustainable, healthy and thermally comfortable for urban occupants. This study explores the influence of street grid form, as a single aspect of the urban layout, on wind flow, solar access and thermal stress in a hot climate. Four street scenarios based in Amman, Jordan were simulated under the same climatic conditions using the CFD modelling software Envi-MET. The analysis included different orientations for the designed grids to assess the effect of sun angle and wind direction. The results were compared in terms of average wind speed and physiological equivalent temperature (PET). Although wind speeds were found to change greatly for different orientations, PET was more sensitive to the different grid geometries rather than their orientation
