<p>Toni,</p>
<p> You do not need to draw the cellar below the 0 level in
SketchUp. You will need to specify in SketchUp/Trnsys3d that your
cellar walls and floor are BOUNDARY walls and choose a variable
name for the temperature on the outside of those surfaces.</p>
<p>kind regards,</p>
<p> David</p>

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:<o:p></o:p></span></p>
