Do the rooms have to be adjacent?

"In case I simulate an entire building, do adjacent rooms have to be connected by walls for the calculation to work correctly, or is the simulation accurate simply by choosing an interior wall, regardless of whether the rooms are adjacent? I noticed that a room always has to have side and back walls, so I'm wondering if I need to place half the wall width (so that in adjacent rooms it's the correct width), or do I need to set the exact wall width for each room and mark the wall as interior?"

If you turn on “Connect adjacent rooms” under “Advanced settings” you will get thermal conduction between the zones. The distance between the zones does not have to be exactly the same as the wall thickness for the zones to be thermally connected through their common wall. Largest allowed distance is 0.5 m horizontally and 0.8 m vertically. Larger distance will give separate adiabatic walls.

If you don’t turn on “Connect adjacent rooms” (default) the inner walls will be adiabatic, but you will still have thermal interaction (storage) with half of the wall. In both cases you should model the inner walls with their full thickness.
