PET values obtained were matched with the comfort levels of the individuals and the relationship between these values tried to be determined. As a result of the study, it was found that all comfort intervals are different, sunlight directly affects the comfort value, and the perceived and calculated PET values are different. As a result of the study, it was concluded that with the improvement of thermal comfort conditions of people outdoor they prefer to use outdoor spaces longer.
