Smart building visualization systems integrate building information with 3D virtual models, offering intuitive data presentation and efficient decision-making. These systems comprise a sensor network for real-time data collection, a data processing center for analysis and control, and user interfaces (e.g., control room screens, mobile apps) for data display and facility control. Key functions include environmental monitoring and regulation, energy management, security monitoring, intelligent navigation and access control, and facility maintenance with fault prediction. These systems enhance comfort through personalized environments, improve work efficiency by optimizing resource allocation, increase security with real-time monitoring, and offer convenient interactive experiences. AI-powered systems further boost efficiency by automating alerts and problem detection.
