[TRNSYS-users] Modelling of a flat below the ground

[Toni Calabrese]

Hi,
I have a question. I am modelling a MFH in SketchUp and I need to model the cellar. The cellar is (of course) below the ground, but I do not understand how Trnsys will recognize that the cellar is below the ground (i.e. not directly hit by the solar radiation). Here my questions:

1)     Need I to draw the cellar below the "0" level in SketchUp? In SketchUp "-1m" means that I am drawing a flat 1 m below the ground?

2)     Or need I simply to specify in TRNBUILD that the wall is a boundary wall (T ground) and automatically TRNSYS recognize that the wall is not hit by the solar radiation?

Thanks a lot and a nice afternoon.
