Simulating a physical energy system, it verifies proposed planning scenarios for energy usage, providing recommendations on how to optimize desired outcomes including energy efficiency and associated cost savings, as well as emission reduction. "By accurately modelling operational and energy usage scenarios, the Digital Energy Twin enables faster and more transparent decision making in the early planning phases," said Matthias Rebellius, Member of the Managing Board of Siemens AG and CEO of Smart Infrastructure. "This demonstrates how at Siemens we are combining the real and digital worlds to drive scalable, sustainable progress in industries, and represents an exciting first step towards an integrated process for optimized planning, building operation, and production."
