    Effect of urban geometry on pedestrian-level wind velocity
    (EarthscanJames and James 14a St. Cross Street Clerkenwell London EC1N 8XA, 2014) Celen Ayse Arkon; Ünver Özkol; Arkon, Celen Ayse; Ozkol, Unver
    The orientation of the streets and the height of continuous buildings cut off summer breezes and the prevailing wind in Izmir Turkey. Compared with the northern parts of Turkey the summer period in Izmir is relatively hot humid and long. Due to the dense urban structure and the expansion of hard surface materials the temperature in the city centre is higher than this centre's surroundings and this effect is called the urban heat island. Consequently pedestrian comfort in the city drops dramatically especially in locations where the wind flow is obstructed by buildings. In addition natural ventilation through the building façades is weakened due to the low average wind speed in the streets. For better outdoor and indoor comfort the citizens in Izmir should benefit from the prevailing wind and summer breezes locally named imbat in the sea-land direction. Therefore the existing situation is examined through the field study in order to understand the natural ventilation potential at the pedestrian level in the selected main streets in Izmir. © 2013 Taylor and Francis. © 2014 Elsevier B.V.
