“…A large number of comfort temperature values are within the upper and lower adaptive temperature limits, although some exceed the limits. This result agrees with recent studies focusing on student wellbeing in NV classrooms with wide ranging comfort temperature [32,33,61,62]. According to another recent study [12], the thermal comfort state of the students is outside the comfort zone prescribed in the ASHRAE standard.…”

“…The mean value of comfort Table 5 shows a comparison of comfort temperature with previous studies. The comfort temperatures obtained in this study were similar to those in previous studies conducted in NV classrooms during summer [9,23,61,62]. Field studies conducted in the sub-tropical areas show a lower comfort temperature than in the present study because of outdoor climatic conditions [16,63].…”

“…The comfort temperature of the present study is 2 • C lower than the comfort temperature in a study in schools in Indonesia during autumn [19]. It is also 0.4 • C higher than the comfort temperature calculated for summer in NV classrooms in India [62]. The comfort temperature of this study is 2.2 • C higher than the study conducted under a high metabolic rate of students during autumn and also found that female students had higher comfort temperatures than males [33].…”

A comfortable indoor environment is essential for students' health and academic performance in schools. As no major concerns were raised on the thermal comfort of students in Nepalese schools, we investigated the present condition of students' thermal comfort in school buildings in the temperate climatic region of Nepal. A survey was conducted on the indoor thermal environment and the associated thermal perception during the middle autumnal season in 2017. Altogether, 818 students participated in this survey; they voted three times: at the beginning, in the middle, and at the end of each 45-min lesson. Under the condition of natural ventilation, the indoor globe temperature was close to the outdoor air temperature. Approximately three quarters of the students felt comfortable at an average temperature of 27 • C. Private school students perceived a low estimated comfort temperature, which may be due to wearing more clothing insulation. Even though there is a dress code, students reduced their clothing to adapt to outdoor thermal environment, whose air temperature is above 30 • C. This study provides the adaptive thermal comfort system for Nepalese school students under natural ventilation during the middle autumnal season.

“…Similar inferences were made by Mishra & Ramgopal, 84 Kumar et al, 85 Thapa et al, 86 and Jindal 87 for other building typologies and climatic conditions. Researchers also investigated the role of occupant factors such as age, gender, clothing, thermal history, social practices and witnessed stark differences in occupants’ thermal preferences, and adaptation 48‐49,88,89 .

Indoor Air. 2020;30:377-395. | 377 wileyonlinelibrary.com/journal/ina | INTRODUC TI ONThermal comfort is defined as the condition of mind which expresses satisfaction within the thermal environment and is assessed by subjective evaluation. 1 Though this definition aptly stresses on judgment of comfort being a cognitive process, it does not describe precisely as to what is meant by the condition of mind or satisfaction. 2 Thermal comfort, in general, depends on six environmental and personal parameters-air temperature, mean radiant temperature, air velocity, relative humidity, clothing level, and metabolic rate. 3 The adaptive model further considers the effects of psychological, physiological, and behavioral aspects in determining comfort but only at an aggregated level. Moreover, aspects related to sociocultural practices, thermal history, context, and income are not comprehensively considered in the existing thermal comfort models. 4-6 This increases the complexities in evaluating thermal comfort and hence even after significant years of research in this domain, predicting conditions to ensure comfort remains imprecise.Thermal comfort studies are necessary because they have a significant impact on occupant's health, well-being, and productivity. [7][8][9] Long-term exposure of subjects to indoor environments, which are not acceptable, causes discomfort leading to negative health impacts. 8 At the same time, in the era of energy deficit and prudent energy consumption, the need to study thermal comfort becomes even more crucial as it dictates the energy use in buildings. 10,11 Additionally, increasing dispensable income, lowering cost of energy services and the desire for thermal delight among the occupants has led to changes in comfort preferences, behavior, and usage patterns. AbstractThis paper presents a review on thermal comfort research that is informed by changes in occupant behavior, lifestyle, and income leading to rebound or pre-bound effect. It explores the current state of research in thermal comfort domain through a systematic review to identify the gaps and opportunities specifically focusing on energyintensive developing countries. This review argues that adaptive thermal comfort is a continuously evolving domain owing to dynamic modifications in occupant behavior occurring from changes in the cost of energy services and preference of comfort (rebound/pre-bound effect). A conceptual framework linking thermal comfort, rebound/pre-bound effect, and occupant behavior is forwarded through the introduction of an exogenous factor related to occupant well-being. The results ascertain that there is a need of localized thermal comfort model with an occupant-centric approach that can help in enhancing comfort and reducing energy consumption.
