This paper explores thermal comfort assessments under transitional states. Toward this end, multiple groups of participants moved in a laboratory building through a number of spaces with different thermal conditions. The thermal sensation and comfort evaluations of the participants were assessed before transition, immediately after the spatial transition, and after a short period of adaptation. The main objective of the study was to compare participants' thermal comfort assessments immediately after a spatial transition with those of thermally adapted participants. The results suggest that the change in people´s expressed thermal sensation vote (TSV) immediately after a spatial transition is consistent with the respective temperature difference. The change in thermal comfort vote (TCV) immediately after a transition, however, did not consistently follow the temperature difference pattern. Rather, it was found to be consistent with a proposed new measure "effective temperature difference (Δθeff)".
