For 1, I would suggest that you ignore the windows in the basement
as far as Trnsys3D is concerned. My guess is that their impact on
the house will be more significant as a source of energy conduction
and less as a solar gain to the basement. Because of that, I would
treat them as a small (opaque) wall instead of as a window. Once you
get to TRNBuild, you can associate them with some thermal properties
that account for the thermal insulation of the glass but doesn't
bother with the light transmittance.<br>
<br>
For 2, I am not sure there is a specific tool. In TRNBuild, you
should be able to tell what zone they are part of. I would then hide
all the other zones in the Trnsys3D project. If the remaining zone
isn't too complicated, you can always delete it and start over. You
might also be able to look at the *.idf file itself (which is text)
to determine the surface name (a bunch of letters and numbers) that
have been associated with the surface. <br>

Trnsys3d:</font>
</p>
<p><font face="sans-serif" size="2">1. I
am working on a building that has a cellar with windows. When
I convert
the idf-file into a TRNBuild-file (b17 idf-file) the cellar
walls are shown
with a wrong area (takes the net area = gross area minus
windows instead
of the gross area) and the windows are missing. Is it not
possible to include
windows in walls that have the ground as a boundary? Of course
the house
has a light well, but I thought I could solve the problem by
just drawing
the windows and setting them to a high shading factor.</font>
</p>
<p><font face="sans-serif" size="2">2. Is
it possible to list all the drown surfaces in a building? I´ve
always used
the surface search so far but I have two lines (drown by
accident) that
are recognized as walls with an area of 0.001 m² and I don´t
know where
they are, so it´s like searching for a needle in a
haystack...</font>
