Evaluating the performance of bioclimatic indices on quantifying thermal sensation for pedestrians
Previous studies have shown that bioclimatic indices predictions differ from actual thermal sensation and that their predictability varies depending on the climate. This study aims to assess the potential of a large number of widely used bioclimatic indices to describe human thermal sensation as well as to identify the one that most successfully simulates thermal sensation in a Mediterranean urban environment. Field questionnaire surveys were conducted along with weather measurements at three sites with different microclimatic characteristics in Athens, Greece. The predicted by the indices thermal sensation was compared to the actual thermal sensation that was indicated on a seven-point thermal sensation scale by the respondents, named as thermal sensation vote. Three statistical and one qualitative criterion were applied. Analysis showed a significant correlation between predicted and actual thermal sensation, indicating a strong correlation when indices classes were taken into account. The majority of indices predicted successfully about 35% of thermal sensation votes, while the maximum percentage of successful predictions was estimated to be 57.9%. The four criteria used were sufficient to evaluate indices performance. Subjective Temperature Index and Universal Thermal Climate Index showed the best applicability compared to all the indices studied.
