Costume Materials

Hi all,

I am simulating a trombe wall connected to a house with multizones.
I have a construction set for the main building with thin internal walls.
For the Trombe wall, that is unconditioned and adiabatic wall with the main building, has a consruction set that is same as the rest of the building exept for the inner walls are earth material/ high mass.

I want to differenciate the interal walls from the main building and the one between the trombe zone and main building (adiabatic wall). How I have it now, that wall is both the interal wall of the main building and trombe zone. Since inputed two different systems, it gives me an error.

How do I “tell” grasshopper what I want (a high mass adianatic surface)?

Thank you for your time :slight_smile:
