[Equest-users] Existing building simulation

[David S Eldridge]

Your model results have very little energy for fans and cooling (and basically no heating) - I'm not sure what you would calibrate.  The actual data seems to show a much more pronounced weather dependence.

Probably some rough hand-calcs to check against annual fan and cooling energy usage estimates might be a good place to verify your model inputs for the HVAC systems.  I think you have a little bit of debugging of the inputs to go before thinking about "fine tuning" or calibrating.

If we are doing a simulation for an existing building and the actual electricity consumption does not match with the simulation, how can we adjust/calibrate it?

The snapshot shows the actual (blue graph) vs. simulation.
