Purpose By harnessing technology developments such as Internet-of-Things (IoT)-enabled intelligent sensors and immersive virtual reality (VR) experiences, facility managers can access real-time, precise information on thermal comfort-related indicators through models. While prior research studies have developed key technologies for improving the understanding of comfort its impact occupants’ well-being productivity, there remain areas yet to be explored, especially in relation integrating both real-time data from multimodal IoT-enabled smart VR technologies. Hence, this study demonstrates potential IoT assessment visualization well user interaction with HVAC systems enhance comfort. Design/methodology/approach To develop proposed integrated analytical framework paper, various steps were implemented. First, four sensing stations created installed collect (i.e. temperature relative humidity). Second, a environment was using Unity engine offer an experience. Third, into by transmitting it cloud via MQTT protocol server, programming scripts provide multiple functionalities users, including visualizing along entire indoor space interacting controlling cooling heating systems. Fourth, applicability effectiveness validated evaluated 92 participants survey questionnaire. Findings The obtained results importance aspects graphical satisfaction, spatial presence, involvement, experienced realism, low-to-no cybersickness overall application among others. More specifically, findings reflected that participants’ average scores sense involvement realism 4.69, 4.61, 4.71 4.53 out 5, respectively. showed capabilities serve powerful feature enables comprehensive variations across room/office space. Also, no statistically significant differences between responses experience those limited-to-no experience, thus further highlighting usefulness not only users but also different skills background. Originality/value This has revolutionize way built environments are managed interacted with, where monitor, assess visualize interact control devices real-world distance framework’s ability dynamic continuously updated assessments conditions positions valuable tool prompt adjustments optimize levels. Ultimately, provides intuitive platform manage comfort, promoting healthier, more productive eco-friendly environments.

People spend most of their time indoors. However, indoor temperature and individual thermal exposure are generally not considered in epidemiological studies health. Based on the American Society Heating, Refrigerating, Air-Conditioning Engineers (ASHRAE) RP-884 Database, ASHRAE Global Thermal Comfort Database II Chinese this study first explored relationship between outdoor temperature, sensation from a global perspective. Moreover, potential influence spatiotemporal heterogeneity health was explored. A breakpoint found at approximately 11.5 °C segmented regression slope curve greater when above (n = 67,896). multi-group propensity score matching (PSM) generalizedadditivemodels (GAM), temperatures after adjusting for building type year. Furthermore, influenced by temperature. This highlights importance considering or temperature-related studies.

Occupant Centric Control (OCC) strategies aims to achieve a more personalized and comfortable indoor environment, translating occupants' comfort requirements into real environmental conditions. This strategy relies on multilevel non-linear programming optimization procedure determine optimal thermo-hygrometric setpoints. The objective is minimize space heating cooling while addressing multi-domain concerns related individual thermal sensations perceived air quality. To facilitate this process, study adopts novel Personal Comfort Model (PCM), incorporating physiological factors predict CO2 intakes. PCM's reliable predictive capabilities are confirmed through validation with experimental data from test room at the University of Perugia. For detailed energy analyses, considering subjective preferences, PCM seamlessly integrated DETECt, an in-house building performance simulation tool developed by Naples Federico II, for design advanced control algorithms efficiency strategies. effectively manage HVAC system, model implemented, using determined setpoints ensure mechanical ventilation maximize cost savings. proof concept methodology involves simulating tests human body new facility management be simulated optimized means enhanced tool, exploited operation occupant-centric sustainable buildings. proposed demonstrates that OCC enables significant reduction in discomfort (40% 60% less than occupation time 1 2, respectively) compared reference scenarios.
