if you use EXTERNAL category, ambient temperature will be considered on outside wall surface. (You can also use BOUNDARY category with external temperature as input, but wall orientation won't be considered).
If you want to put ground temperature as external wall temperature, you may choose "BOUNDARY" in category wall, and define a ground temperature input (which is defined in Studio)
For information, Type 501 from TESS Library give a Soil Temperature Profile.

Good afternoon everyone, Within type 56, I have created an active layer which is the ground floor of the building I am modelling. When I define this active layer, in "category", I put "EXTERNAL". Is that mean that the software considere that the temperature on the outside surface of the layer is the outside ambiante temperature? In this case obviously it won't be right because it is not the outside ambiante temperature but the ground tempereature which should be defined. How should I do to model it right? Should I use the category "BOUNDARY" instead of "EXTERNAL"? In which case is it clever to use the BOUNDARY category? Thank you very much.
