High-performance buildings are greatly influenced by the occupants' behavior, which impacts energy consumption from various building systems and technologies. IoT-based systems opened up opportunities for advancements in building management, leading to potential energy savings in buildings through intelligent control of energy systems. Ensuring occupants' satisfaction with their environment is crucial for the overall building performance. To this end, the development of smart technologies based on the Internet of Things (IoT) has paved the way for further advancements in personal thermal comfort modelling, potentially leading to energy savings in buildings. In this study, a methodology and the results of a thermal comfort experiment were presented for a University building in Split, Croatia. To gather accurate and comprehensive data, wearable sensors, in the form of a smartwatch, were employed for continuous monitoring of various personal parameters, including skin wrist temperature and heart rate. Simultaneously, environmental thermal comfort and air quality parameters such as air temperature, relative air humidity, CO₂ concentration and volatile organic compounds (VOCs) were measured in the rooms. To complement the objective data, subjective responses from the occupants were collected through a conducted field survey. This comprehensive approach provided deeper insights into personal thermal comfort, enabling the use of field data for modeling and establishing a smart regulation of building energy systems. This research highlights the growing importance of personal thermal comfort in high-performance buildings and demonstrates the potential of smart technologies to optimize building energy systems and foster occupant well-being. As smart buildings become more prevalent, the understanding and implementation of personalized thermal comfort strategies will play a crucial role in achieving sustainable and energy-efficient building environments.
