Creating a Digital Twin of an Electric Utility: Reimagining Building Energy Modeling in a World of High-Performance Computing, Big Data, Imagery, and Advanced Metering Infrastructure

CEEESA Seminar

Abstract: Buildings consumed 45% of U.S. primary energy consumption (73% of all electricity) in 2017, contributed 39% of national CO2 emissions, and constitute a $395 billion/yr national energy bill. Building energy modeling (BEM) can be used to find the most cost-effective energy conservation measures for a building, but more scalable approaches are needed for industry to make actionable business decisions. Development of urban-scale building energy models is becoming increasingly tractable for many applications including city-wide energy supply/demand strategies, urban development planning, electrical grid stability, and urban resilience.

I will discuss Oak Ridge National Laboratory’s Automatic Building detection and Energy Modeling (AutoBEM) technologies for creating models of buildings at university campuses and city-sized areas. A case study for creating a digital twin of an electrical utility and evaluating value propositions for BEM-leveraged use cases will be discussed that was enabled via partnership from the Electric Power Board (EPB) of Chattanooga and involves comparison to 15-minute data from over 150,000 buildings.
