This study investigates the advancement and utilization of AI-driven digital twin (DT) systems, emphasizing their incorporation with virtual reality (VR) and 3D technologies for the real-time monitoring and optimization of physical assets. A DT is a virtual depiction of a physical asset, facilitated by data and simulations, that provides significant capabilities for prediction, monitoring, and decision-making. This study introduces the modern technologies methods, which examines the role of intelligent building design elements like multi-layout activities and AI simulation model-derived functions in DT-based smart building systems. This study utilizes a modern house to illustrate the application of DT across many capacity tiers, underpinned by data gathered from an array of sensors within the dwelling. These smart models can be visualized and engaged with in a VR environment, offering an immersive platform for users to examine and modify the virtual house.
