“…Atmosphere 2024, 15, x FOR PEER REVIEW 4 of 20 [20,21,25,26], measurements were carried out in different seasons. In this study, experimental measurements were carried out on different days in the summer season in order to obtain the heat stress indices [4] such as UTCI [18,19,21,34,[39][40][41][42][43], PET and mPET [32,33,[40][41][42][43], SET [37,38,40,41,43] and WBGT [34][35][36]41] for the assessment of temporal and cumulative outdoor thermal comfort. Furthermore, the heat stress exposure (HSE) metric [50] was also evaluated using UTCI, as in [50], and using the other indices as well.…”
