A good example of the use of 'digital twins'. Challenge will be to get the required detail for so many buildings with different ages, designs, updates, designs. Shows both the possibilities and the complexity involved.
ORNL's Simulation Tool Creates Digital Twins of Buildings From Coast to Coast
Oak Ridge National Laboratory, August 11, 2021
Modeling software designed by researchers at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) can simulate the energy profiles of all 129 million buildings in the U.S. The researchers developed the Automatic Building Energy Modeling (AutoBEM) software suite to realize ORNL's five-year Model America vision of producing digital twins for all U.S. buildings. AutoBEM uses high-performance computing to collect publicly available data like satellite imagery and street views, then generates a building energy model to forecast which energy-saving technologies could be implemented. ORNL's Joshua New said, "Before this program, no one had the capability to perform that analysis with detailed, building-specific energy modeling at this scale. Individual utilities now have the capability to perform modeling to show the potential of reducing demand and greenhouse gas emissions."
