Summary: This study investigated the effects of perceived control on human thermal sensation and comfort in heated environments through a psychological experiment. The results revealed that the influence of perceived control on thermal sensation was related to individuals' thermal expectations. For those with strong expectations for a neutral environment, perceived control improved thermal sensation by meeting their expectations. However, for those with low thermal expectations, perceived control decreased their tolerance to the environment, ultimately leading to thermal discomfort.

Summary: Both olfactory and thermal environments have significant effects on thermal sensation, thermal comfort, and total comfort. The olfactory environment has a stronger influence on total comfort compared to the thermal environment. However, the thermal environment affects physiological indicators such as skin temperature, heart rate, and blood pressure, while the olfactory environment does not have a significant impact on these indicators.

Summary: The model of personalized thermal comfort can be improved using machine learning algorithms, which require a substantial number of thermal votes. However, collecting these votes may be undesired by the occupant. This paper proposes a meta-learning algorithm to reduce the required number of votes and derive a method for quick identification of personalized environmental conditions.

Summary: Cold climates require mechanical heating, leading to increased energy consumption. Personalized local heating can save energy, but the thermal perception capabilities of different body parts remain unclear. This study found that using local heating devices with fixed surface temperatures significantly improved overall and local thermal perception and comfort in cool environments. Heating the waist had the strongest effect, improving overall thermal perception and comfort, while heating the knee and chest showed the least improvement.

Summary: The luminous environment has a significant impact on the efficiency of undergraduate learning, with the correlated color temperature (CCT) being an important factor in affecting learning efficiency and fatigue. The study found that different CCTs can regulate subjective thermal perception and attention and relaxation levels among undergraduates. Recommended CCTs for optimal learning and rest environments at different temperatures were identified to provide a comfortable and efficient lighting environment for undergraduates.

Summary: The experiment explores the effects of wearing medical surgical masks on human thermal sensation, thermal comfort, and breathing comfort in office buildings in summer. Results show that wearing masks significantly impacts subjective thermal sensation, comfort, and breathing, with high-temperature and high-humidity microclimates causing poor tolerance and discomfort. As environmental temperature rises, the impact of wearing masks becomes more significant.

Summary: Personalized thermal sensation models are important for ensuring occupant's thermal comfort and improving building energy efficiency. This paper investigates the factors influencing thermal sensation vote and proposes a personalized regression model using local skin temperature as the key indicator. The model effectively incorporates individual characteristics to capture and compensate for individual differences.

Summary: In order to ensure both comfort and energy efficiency of intelligent temperature-controlled equipment, we designed a smart decision-making system that predicts the most appropriate thermal comfort adjustment mode based on environmental factors and human body parameters using supervised learning models. Through comparison and evaluation, we identified the Deep Forest model as the best performer, providing accurate application and simulation results.

Summary: Preschool children have different thermal comfort perceptions compared to adults, and parents or grandparents may create an inappropriate thermal environment for their children. Preschool children have a higher tolerance to cool environments compared to adults, requiring lower neutral temperatures and wider acceptable temperature ranges. Touching the children's skin can help parents more accurately infer their thermal perceptions.
