[EnergyPlus_Support] Re: interior walls in a one zone model


Dear Linda, Jeremiah, and Griffith

Thank you very much for your answers. 

Unfortunately my central question remains a little unclear to me:
What kind of surface should I use in order to account for the thermal inertia of an interior wall in a single zone model?

Should I use Wall:Detailed or BuildingSurface:Detailed object? What would I choose as "Outside Boundary Condition"?

I was considering the Internal Mass object before, but decided not to use it, because it will not appear in the graphical (dxf) representation and I guess it might falsify the solar gains.

Thank you again!

Kind regards
Niko
