Hi, I am simulating natural ventilation with solar chimney concept in a room with walls, surrounded by a rectanglar enclosure as the ambient outdoor air is planned to be considered as well.

I know that usually for aerodyanmics, geometry has to be removed by subtracting itself from the enclosure. But now for building ventilation, I would like to take the wall heat exchange and thermal conductivity into account, assigning composite wall material layers, rather than just subtracting the room domain inside the enclosure.

Q: Can I mesh the room domain inside the meshed enclosure without substraction, if yes, how could I manage to do so? Thank you for the guidance!!!

Subtract+retain, or Split will do what you want. Just remember to check you only have single volumes (ie no duplicates) when you finish. Then make sure you use a multibody part or Share Topology depending which geometry tool you're using.

Yes, you can mesh inside of your enclosure. If using SpaceClaim/Discovery, you may want to check for interference (Prepare > Interference) between volumes and then apply Share topology between your volumes to have a conformal mesh between them.
