From the original attention on residential buildings, thermal comfort-related issues are increasingly also involving tertiary buildings, since people tend to spend an increasing amount of time on such premises. This opens to a rethinking of the available methods for evaluating thermal comfort conditions. In fact, in tertiary buildings, people usually experience the confined environments differently compared to the residential ones in terms of both permanence (in that confined environment) and modalities of moving inside them. In museums, for example, people stand for a certain amount of time in front of a given artwork and, in order to take best advantage of the exhibited artefact, need pleasant thermal and visual conditions around. For this purpose, it is fundamental to study the dependence between indoor climate experience and occupants’ comfort expectation. Clearly, this requires a reflection on the assessment method of the confined environment to be used, even more when considering that the indoor comfort conditions are more frequently included within the economic criteria that define the whole quality of buildings. However, the fact that the attainment of high-level comfort conditions by necessity involves the use of energy for the building’s air-conditioning must be properly taken into account. On the other hand, as for the residential buildings, the new evidence concerning adaptive comfort must be considered. Additionally, current tools such as multi-agent schemes, aimed at the assessment of subjective indoor comfort, are increasingly gaining foot. Finally, the changing layout and metabolism of cities determine new spaces where people live and work, which cannot be classified as either indoors or outdoors. In these cases, a different approach to the thermal comfort evaluation is needed. Hence, all the above-cited issues should become part of the rationales for modelling indoor thermal comfort.
High-quality papers addressing the above-mentioned issues (though not limited to these) are solicited, with particular interest in theoretical and experimental analysis with the aim of providing new methods, new indicators, or new data useful for the evaluation and the achievement of indoor thermal comfort.
