Ground temperature

Dear Trnsys users

What is the value we must take for the external convection coefficient of the floor, while we are describing a building in the Prebid?

And how to model the influence of the ground temperature?

Note that in the Trnsys examples, the value of Hback was very low, and the ground temperature was fixed.

Thank you in advance.

Best regards.
