STUDY ON THE EVALUATION OF THERMAL COMFORT AND DISCOMFORT BASED ON COGNITIVE TEMPERATURE SCALE OF OCCUPANTS. Study on human cognitive temperature under the radiant and convective heating systems in winter. Yuji SASAKI*1, Masaya SAITO*2. *1 Hokkaido Research Organization, Building Research Department, M. Design.. *2 Prof., School of Design, Sapporo City Univ., Dr. Eng.. In recent years, ZEBs, ZEHs, and other eco-buildings have been constructed both in Japan and abroad. If their. occupants can alter their "lifestyle and behavior" in a way that improves the performance of environmental. architecture, it will also bring about higher levels of both thermal comfort and energy conservation. To do so, it is. necessary to first clarify the conditions under which the occupants adapt to the thermal environment and how they. perceive the thermal environment.. International indices such as PMV, PPD, and SET*, which are based on data from an artificial climate laboratory. under steady-state thermal conditions, have been used to evaluate thermal comfort in many countries. These. indicators capture thermal comfort on the assumption that "comfortable" and "uncomfortable" states are independent. of each other. In contrast, the hypothesis of the authors is that the sense of "not-uncomfortable" exists as a nesting. point between "comfortable" and "uncomfortable".. In addition, in recent years, thermal adaptation has received significant attention. Thermal adaptation is a concept. that captures thermal comfort based on the principle that, "If a change occurs which causes discomfort, people react. in ways that tend to restore their comfort." "Not-uncomfortable" is a state that occupants recognize when returning. from the "uncomfortable" state, and is considered to be an unsteady state. Therefore, "not-uncomfortable" can be. considered the first psychological and physiological state of thermal adaptation. From the above discussion, we. assumed that the discrimination of thermal adaptation was based on "not-uncomfortable" responses.. In this study, to quantitatively clarify the "not-uncomfortable" state that is assumed by the thermal adaptation. theory, we conducted experiments on subjects whose thermal environment changed from "uncomfortable" to "not-. uncomfortable" and finally "comfortable", and discussed the results based on the cognitive temperature. The. subjective experiments were conducted in two rooms with radiant (N=13) and convection (N=15) heating during. winter in Sapporo. During the 30-min experiment, the subjects responded consecutively to three psychological. quantities: cognitive temperature, thermal comfort, and thermal sensation. . Following are the results of the experiments. . 1) Cognitive temperature was higher in the AC room than in the PH room for 20 min after the start of the experiment.. In contrast, the temperature of the PH room was 0.3 0.5 higher than the AC room after 20 min of the experiment.. This suggests that the rise in room air temperature and MRT affected their cognitive temperature. Similar results. were obtained for their thermal sensation and comfort responses. . 2) The subjects in AC rooms were significantly more likely than those in PH rooms to report "not- uncomfortable" at. more than 60% of the time across all time periods. In contrast, the PH room had significantly more "comfortable". declarations than the AC room from 10 min after the start of the experiment, indicating a difference between the. room air temperature and the increase in MRT.. 3) As thermal comfort responses change from “uncomfortable” to “comfortable” via “not-uncomfortable,” and thermal. sensation responses change from “cold” to “hot” via “neutral”, this implies that cognitive temperature rose. From this. result, the existence of the “not-uncomfortable” state became clear. . 4) Cognitive temperature scale was higher than room air temperature when the subjects described being “comfortable.”. Therefore, the difference between cognitive temperature scale and room air temperature can be used to estimate. whether occupants have adapted to a thermal environment.. 2012 pp467-468. 2014.9 17) Omi, Y., Kikuta, K., Sakata, T., Saito, M. and Hayama, H.: Exergy. evaluation of indoor environment of northern regional houses in summer, Journal of Environmental Engineering, (Transaction of AIJ), Vol.79, No.696, pp.159-166, 2014. 2 (in Japanese). 79 696 pp.159-166 2014.2 18) Takebayashi, Y. and Rijal, H.B.: Study on the cognitive temperature..
