The importance of field studies, especially in investigation concerning the adaptability of people, comes from the need of investigating thermal comfort responses within the naturally occurring context. On the contrary, as previously highlighted, the classical methodology of assessing thermal comfort comes from results from researches on fully controlled climate chamber. The typical approach for field studies consists of administrating a questionnaire to a
group of occupants while the investigator records certain macroclimatic parameters [7]. In this situation, people’s answers refer to the very thermal environments to which they are subjected in their everyday life [17].
