A Digital Twin for Smart Green Asset Lifecycle Management is a dynamic, virtual representation of a physical asset, system, or process that integrates real-time data, analytics, and predictive insights to optimize the asset’s performance throughout its lifecycle. It enables sustainable decision-making by simulating scenarios, monitoring resource efficiency, and ensuring compliance with green standards. By leveraging IoT sensors, AI, and BIM, a digital twin enhances collaboration, reduces environmental impact, and supports proactive maintenance. This approach aligns with smart infrastructure goals, promoting energy efficiency, cost savings, and long-term sustainability for buildings, infrastructure, and other assets in a digital-first, eco-conscious framework.
