“…In another study, Kumar et al (2016) investigated the effect of green roofs on thermal performance and cooling potential. Lachireddi et al (2017) measured air velocity, globe temperature, ambient temperature, RH and illuminance in eight hostels and simultaneously surveying students to determine their thermal sensation vote and thermal preference vote on an ASHRAE seven-point scale. Horrison and Amirtham (2016) quantified the impact of urban growth patterns defined by orientation, street geometry and ground cover on climate parameters.…”

Purpose Science mapping is an essential application of visualization technology widely used in safety, construction management and environmental science. The purpose of this study was to explore thermal comfort in residential buildings (TCinRB) research in India, identify research trends using a science mapping approach and provide a perspective for recommending future research in TCinRB. Design/methodology/approach This study used the VOSviewer tool to conduct a systematic analysis of the development trend in TCinRB studies in India based on Scopus Index articles published between 2001 and 2020. The annual numbers of articles, geographical locations of studies, major research organizations and authors, and the sources of journals on TCinRB were presented based on the analysis. Then, using co-authorship analysis, the collaborations among the major research groups were reported. Furthermore, research trends on TCinRB studies were visually explored using keyword co-occurrence analysis. The emerging research topics in the TCinRB research community were discovered by analyzing the authors’ keywords. Findings The findings revealed that studies had been discovered to pay more attention to north-east India, vernacular architecture, Hyderabad apartments and temperature performance in the past two decades. Thermal adaptation, composite climate, evaporative cooling and clothing insulation are emerging research areas in the TCinRB domain. The findings summarized mainstream research areas based on Indian climatic zones, addressed current TCinRB research gaps and suggested future research directions. Originality/value This review is particularly significant because it could help researchers understand the body of knowledge in TCinRB and opens the way for future research to fill an important research gap.

“…This is a commonly used method for assessing the thermal comfort of premises. The researchers have shown that in hot and humid climate, this model is unsuitable because of too much variance in real and calculated values, which was shown in [5]. However, the location of the analyzed objects in Na podstawie parametrów uzyskanych w symulacji obliczono wartość wskaźnika PMV na długości pomieszczenia z interwałem 1 m. Do analizy wybrano model Fangera wg normy [4].…”

“…Jest to powszechnie stosowana metoda do oceny komfortu cieplnego pomieszczeń. Naukowcy wykazali, iż w klimacie gorącym i wilgotnym model ten nie sprawdza się z uwagi na zbyt duże odchylenia wartości uzyskanych w warunkach rzeczywistych i obliczonych, co pokazuje [5]. Jednak lokalizacja analizowanych obiektów moderate climate allows for successful application of the chosen model.…”

“…They discovered that the majority of the dormitories lacked natural ventilation, and the concentration of CO 2 during sleep was too high, affecting sleep quality and the mental state. Currently, research on air quality and thermal comfort in Chinese student dormitories focuses on the summer [18][19][20][21][22], with relatively few studies conducted during the transitional and winter seasons.…”

Most studies on Chinese dormitories are carried out in summer, while few focus on a transition season or winter. This study evaluated the air quality of a student dormitory in a university in the Beijing area by using a questionnaire survey and on-site measurements. The CO2 concentration was used as an indoor air quality evaluation index to characterize the freshness of the air, and different window opening conditions in the dormitory were simulated, with corresponding improvement plans proposed. The results of this study revealed that the air quality and thermal comfort of the student dormitories during a transition season and winter fell short of expectations. According to the survey, students who opened their windows frequently had a better subjective perception of the air quality. However, due to the large temperature difference between day and night, more than 80% of the students felt too cold when opening the windows. For daytime conditions, the area of unilateral ventilation window opening should not be less than 0.39 m2, the area of bilateral ventilation window opening should not be less than 0.13 m2, and the time taken to close the windows and doors should not exceed the maximum ventilation interval. Empirical equations were fitted for nighttime conditions based on the CO2 concentration, number of people in the room, and window opening area, resulting in a reasonable window opening area of 0.349 m2~0.457 m2. In sum, this study assessed the air quality status within typical university dormitories across varying seasons, gaining a clear understanding of how different ventilation strategies and occupant densities influence air freshness and thermal comfort. Based on these insights, a practical and optimized window area recommendation was formulated to enhance the indoor environmental quality in these dormitories.
