“…Sensory and physiological responses based on the skin temperature at seven skin points and core temperature were sampled from 10 tropically acclimatised female participants. In this study, the participants were asked to wear head scarfs, hence resulting in a clo value of 0.7, which is slightly higher than the clo value for formal office clothing ensembles worn by western women during summer, namely 0.5 (Vecchi et al , 2017). Although this sample was observed to have a higher clo value, multiple BMI categories and exposure to temperature differences of 17°C (i.e.…”

PurposeRecent studies have found that the high demand for air-conditioning usage in tropical countries has affected the thermal adaptability of building occupants to hot weather, and increased building energy consumption. This pilot study aims to investigate the effects of transient thermal environment changes on participants' sensory and physiological responses.Design/methodology/approachThe change of thermal perceptions, skin temperatures and core temperatures when exposed to transient thermal environments (cool-warm-cool) from 10 college-aged female participants during a simulated daily commute by foot to class in a tropical university campus were investigated. Subjective measurements were collected in real-time every 5 min.FindingsThe main finding suggests that participants were acclimatised to cool air-conditioned indoor environments, despite exhibiting significant mean skin temperature differences (p < 0.05). In addition, exposure to uniform air conditioning from 17 to 18°C for 20 min was thermally unacceptable and reduced concentration during given tasks.Research limitations/implicationsThe study focused on thermal comfort conditions in a uniform air-conditioned lecture hall, and the findings may not be applicable for residential and other private building spaces. The distinct temperature difference between indoor and outdoor in the tropical built environment resulted in high dependence on air-conditioning usage. The building occupants' well-being and energy conservation implications of the findings are discussed.Practical implicationsThis study provides the platform for discussion on the dynamics of occupants' comfort level and adopting a more variable thermal environment in tropical spatial transient thermal environments among architects and building management system managers. The findings from this study may contribute to the Malaysian Standards for Energy Efficiency and Use of Renewable Energy for Non-Residential Buildings (MS1525).Originality/valueA knowledge gap in adaptive thermal comfort due to exposure from transient conditions in tropical university campus for energy efficiency revision has been investigated.

Thermal comfort studies have been carried out at Public Elementary School 06 Sukabumi Selatan, Jakarta, Indonesia. The schools that were observed were public schools that relied only on natural ventilation. Climatic parameters, namely air temperature and radiation temperature, relative humidity, and air speed were recorded together with the choice of seven scale subject comfort. The number of students in the state school was 82 people, consisting of 39 boys and 43 girls who were involved in this study. The study subjects were between 8 and 13 years old in public schools. The comfortable temperature of students at Public School 06 Sukabumi Selatan is 27.82°CTa higher than the current Indonesian comfort standard. This research examines the entire study and draws some conclusions from it

This research examined thermal comfort in church buildings in Indonesia by making a comparison between three different Indonesian climatic regions using three different research models. A static model, an adaptation study model and a CFD simulation were used to find the similarities and differences between the results generated from determining thermal comfort in church buildings in the three regions. The comparison revealed that church buildings had different PMV scores at each measuring point that were inversely proportional to the subjects’ response on thermal comfort inside the buildings, i.e. points adjoining with openings affect a low PMV score and a high perceived thermal sensation, and vice versa. The CFD simulation showed that changing the conditions of the openings affects air velocity and flow into the building, which influences the subjects’ thermal comfort response inside the churches.
