Outdoor Thermal Comfort Conditions During Summer in a Cold Semi-Arid Climate. a Transversal Field Survey in Central Anatolia (turkey)
(PERGAMON-ELSEVIER SCIENCE LTD, 2019) Canan, Fatih; Golasi, Iacopo; Ciancio, Virgilio; Coppi, Massimo; Salata, Ferdinando
In the present study the outdoor thermal comfort conditions in Konya (Central Anatolia, Turkey) were examined during summer. This is why a transversal field survey was carried out and over 300 questionnaires were filled by randomly chosen participants. Moreover, environmental variables as air temperature, wind speed, relative humidity and globe temperature were constantly measured. This allowed to relate the thermal perception and preference votes given by the interviewees to the morphological and furniture characteristics of the surveyed sites. Then, taking into account at the same time all the obtained data, a regression line between the thermal perception votes and the corresponding PET (Physiological Equivalent Temperature) values was obtained and a neutral PET value of 26.8 degrees C was calculated. Based on a logistic curve model with the probit function, a preferred PET value of 19.2 degrees C was determined. On the other hand, the PET comfort range of (21.6)-(32.0) degrees C was obtained by considering, as thermal comfort interval, the range (- 0.5)-(+ 0.5) of the ASHRAE 7-point scale. Finally, two outdoor thermal comfort indexes were introduced. The first one, called Turkish Outdoor Comfort Index (FOCI), is able to predict the thermal perception of the considered population in hot conditions. In the second case, the Predicted Percentage of Dissatisfied (PPD) relation was modified based on the surveyed data and outdoor sites.

Outdoor Thermal Perception and Comfort Conditions in the Koppen-Geiger Climate Category Bsk. One-Year Field Survey and Measurement Campaign in Konya, Turkey
(ELSEVIER, 2020) Canan, Fatih; Golasi, Iacopo; Falasca, Serena; Salata, Ferdinando
This study presents an analysis of the thermo-hygrometric conditions in the city of Konya (Turkey). A one-year transversal field surveywas carried out in the Selcuk University campus and 2295 valid questionnaireswere collected. In each questionnaire, randomly selected interviewees provided personal information and judged their perception and thermal preference according to the ASHRAE 7-point and McIntyre scales, respectively. For each interviewee, a value of the Physiological Equivalent Temperature (PET) was calculated based on the values of operational variables obtained from the questionnaires and the environmental variablesmeasured during the survey. This allowed to calculate the seasonal preferred and neutral PETs and the annual PET comfort range. Also, the scale of the PET thermal perception was determined for the Konya population and, more generally, for the inhabitants of the BSk Koppen-Geiger climate zone. Statistical analyzes carried out in terms of Variance Inflationary Factor, multicollinearity assessment and Best Subsets Analysis led to the identification of the Turkish Outdoor Comfort Index, an empirical index able to predict the average value of the thermal perception of a large group of individuals living in the aforementioned climate zone. Moreover, the equations of the Predicted Percentage of Dissatisfied (PPD) were obtained for each season. (c) 2020 Elsevier B.V. All rights reserved.
