Thermal Comfort Assessment of The Urban Mediterranean Climateinfethiye, Southwest Anatolia, Turkey
Recent rapid growth and expansion of urbanized areas has brought an increase in the effects of lowered thermal comfort levels in outdoor spaces within the cities. With the increases in urbanization and tourism in summer period at coastal Mediterranean locations, urban planners and architects are looking more closely at the effect of climate on urban planning for climate adaptation.This study,has been done to reveal the change of thermal perception in this increasing urbanizationduring the summer when the tourist activities increase. Physiological Equivalent Temperature(PET) values were calculated by using hourly meteorological data individuallymeasuredby automatic weather station in the shade and an open spacein July and Augustmonth in which urban bioclimatic conditions are most uncomfortable for coastal Mediterranean cities. During the day, when tourism activities are more intense, large thermal differences between the shady and openspaces were obtained; in open spaces thethermal conditions were very hot for a long period. Significant result was close PET and temperature valuesin the morning until the mid of the day between open and shady observation site. When the wind breeze begin in the mid of the day from cooler sea surface, PET values in the shaded site have decreased quicker than open one until the end of the certain day time.Shading effect has become evident with wind breeze.Inthe evening, we obtainedno difference between shady and exposed areas,when conditions were generally cold and comfortable. Results revealed that the significance of summer wind breeze between sea-land interaction,reduction of long-wavelength radiation of buildings in urban areas, formation of deep urban canyons for thermal comfortin Mediterranean climate. PET values should be considered in urban planning and architectural designfor a healthy and sustainably comfortable urban life.
