When you say " import the temperatures data from my city " which temperatures are your referring to?

The CFD boundary conditions editor is used for a internal CFD analysis. External analysis don't take into consideration the external temperatures.

Please follow the instructions here to prepare your model for an internal CFD analysis: https://designbuilder.co.uk/helpv5.0/#P ... itions.htm

And then run a EnergyPus simulation to generate the CFD boundary conditions for an internal CFD analysis.
You can find an example at the CFD webinar: https://www.youtube.com/watch?v=NS9ixAqUCPA
