Interesting, I have a couple of questions:

- How do model random variables with high variance like occupancy or equipment use? Are you using sensor/monitoring equipment or just trying to model it as best as you can?

- Did you guys use the initial energy model (built by by the design/consultant team) or do you guys build your model from scratch?

- What energy simulation engine do you guys use? I'm just curious if there's any big advantage between the engines for digital twin applications.
