“…Higher comfort temperature than that prescribed by ASHRAE 55 was required for Malaysians in hospitals [349], which was also corroborated by Azizpour et al [350,351] in the study of a hospital in Malaysia. Based on staff evaluations from nine hospitals, Yau and Chew [352] developed an adaptive thermal comfort model for hospital environments with air-conditioning in a tropical climate.…”

“…Azizpour et al. () examined the ASHRAE comfort criteria in a hot and humid region to find correlations between Fanger's PMV and TSV. They found that the neutral temperatures were 26.8 and 25°C, respectively, with TSV and PMV regression models on operative temperature.…”

While there are plenty of anecdotal experiences of overcooled buildings in summer, evidence from field studies suggests that there is indeed an issue of overcooling in tropical buildings. The findings suggest that overcooled buildings are not a consequence of occupant preference but more like an outcome of the HVAC system design and operation. Occupants' adaptation in overcooled indoor environments through additional clothing cannot be regarded as an effective mitigating strategy for cold thermal discomfort. In the last two decades or so, several field studies and field environmental chamber studies in the tropics provided evidence for occupants' preference for a warmer temperature with adaptation methods such as elevated air speeds. It is important to bear in mind that indoor humidity levels are not compromised as they could have an impact on the inhaled air condition that could eventually affect perceived air quality. This review article has attempted to track significant developments in our understanding of the thermal comfort issues in air-conditioned office and educational buildings in hot and humid climates in the last 25 years, primarily on occupant preference for thermal comfort in such climates. The issue of overcooled buildings, by design intent or otherwise, is discussed in some detail. Finally, the article has explored some viable adaptive thermal comfort options that show considerable promise for not only improving thermal comfort in tropical buildings but are also energy efficient and could be seen as sustainable solutions.

“…Mental state is defined as a psychological outcome response to objective and subjective indicators. 15 Emotion is a subjective output of the mental state, and is defined as a mental response resulted from the interconnection between the brain and the physiological actions of the body. 16 When developing attitudes towards the surrounding environment, emotions are initiated and act as a mediator component in the undergoing perception process; thus, they play a substantial role in generating diverse responses.…”

Many complaints about indoor conditions are related to unsatisfactory thermal environments. Most research on Thermal Comfort (TC) considered physical parameters for settings and users yet marginalized the influence of user's psychological aspects in the process of thermal sensation. Immersive Virtual Reality (VR) has been used in the built environment to simulate real scenarios. This research examines the effect of mood states on human evaluation of the thermal environment in virtual settings. Forty-four university students from Jordan participated. The experiment followed the "Experimental Design Method" using thermally controlled chamber and TC evaluation using psychological responses developed by Fanger. The participants completed the PANAS-X pre-mood test before watching a video that targeted eliciting predetermined mood states; anger and happiness. The participants were then immersed in two virtual environments and asked to complete ASHRAE 7-point scale of TC. General Linear model was used to analyse the data. The results revealed a relationship between TC, mood state and quality of the indoor environment. Humans' judgment on TC is a variable mental reaction. The research presents differences between the evaluation of angry and happy people to their thermal environments. This study expands research on the indoor environment quality and develops TC evaluation strategies.
