Hi @Yure,
Sorry that was a bit unclear - by “this cooling makes sense” I meant the heat transfer from the space through the floor as it’s a heat loss to the space.
For the ground temperatures I used “Import EPW” and plugged the ground temperature output into a monthly chart. I’m not sure if it’s possible to apply these ground temperatures as an adjacent condition…
Chris talks a bit about setting boundary conditions here and it looks like the capability has now been included on the code side, but there might not be a component included yet that includes that functionality - if you took that approach you might need to look into using the python SDK
