> The latest buzzword for a 'computer model'...

A digital twin is specifically a computer model that is continually updated with sensor data to mirror its real world counterpart.

So, you'd build a computer model of a building before you construct it. This model would let you you calculate and simulate temperature and airflow, for example. That's a model.

A digital twin is taking that model and combining it with live data, such as sensor data from the security systems, what the actual weather is that day, and which staff are where.

You might find that running costs are higher on Thursdays when the ambient temperature is below 10 degrees C, and that the front door is jammed open, and Bob the receptionist is on duty.
