ABSTRACT
Thermal studies can be carried out both in outdoor and indoor spaces. However, only in recent years the scientific community has turned its attention to thermal study of extreme indoor environments (Virgílio et al. 2008). In fact, the first studies related to extreme thermal conditions were promoted by military exercises, usually associated to extreme climatic conditions (Virgílio et al. 2008). Case studies carried out in expeditions and outdoor work were also an important step in the development and in the understanding of how humans feel in such environments. In this regard, with growing concern to ensure thermal comfort in indoor spaces, several studies have been carried out either in contexts where the thermal sensation of cold is prevalent, as in food industries (Virgílio et al. 2008) or surgical rooms (Gaever et al. 2014, Khodakarami & Nasrollahi 2012), and where the thermal sensation of hot is prevalent, as in some offices, in some classrooms, or in industries of automotive components (Guise 2014, Ismail et al. 2009).
