<font size=2 face="sans-serif">Hallo,</font>
<br>
<br><font size=2 face="sans-serif">thank you both for your quick reply!</font>
<br>
<br><font size=2 face="sans-serif">1. I also thought of implementing the
windows by treating them as walls and since itīs the least complicated
solution for the problem I did it that way now.</font>
<br>
<br><font size=2 face="sans-serif">2. Loading the idf file into a new just
opened Sketchup didnīt work, but the idf text file really helped. Thank
you!</font>

<br><font size=3>Anne-Kathrin,<br>
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>

<br><font size=2 face="sans-serif">Hallo everybody,</font><font size=3>
</font>
<p><font size=2 face="sans-serif">I have several problems with Trnsys3d:</font><font size=3>
</font>
<p><font size=2 face="sans-serif">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><font size=3>
</font>
<p><font size=2 face="sans-serif">2. Is it possible
to list all the drown surfaces in a building? Iīve 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 mē and I donīt know where they are, so
itīs like searching for a needle in a haystack...</font><font size=3>
