RE: [EnergyPlus_Support] interior walls in a one zone model
All three have thermal storage. Unless there are only NoMass materials in a construction, or it is a window, all surfaces are modeled so as to account for dynamic thermal storage. In fact it is hard to turn off thermal storage modeling and it is difficult to really have a true adiabatic surfaces in E+. Using the word ?adiabatic? in that input field is not entirely accurate but it was chosen as a concise and approximate term for the concept ?the-other-side-face-of-this-surface-has-the-same-boundary-conditions-as-the-inside-face-of-this-surface-and-there-is-no-corresponding-interior-partition-surface-in-an-adjacent-zone.? It does come out to be effectively adiabatic when the zone is well-controlled and zone conditions do not change over time.

Walls that are ?Adiabatic? in EnergyPlus still store and release heat. They have the same boundary conditions on both faces. When those conditions are varying, then heat will flow in and out of the wall and get stored and released in the thermal mass.
Brent- Thanks for correcting my mistake, however I am now curios if you could please elaborate?
So are you speaking of using the outside boundary condition of "zone" or "surface" or "adiabatic" or any/all of these?
