[TRNSYS-users] problem adjacent window and window as external wall

[David BRADLEY]

Thomas,
   First, whether you are dealing with an EXTERNAL or an ADJACENT window 
that has no opaque component, treat it as though it did; draw the wall 
in SketchUp and then make a window in it that takes up almost the entire 
area of the wall (I usually make set my windows in so that there is 
about a 10cm border of actual wall around their perimeter). The engine 
on which Trnsys3D is built has trouble sometimes if the edge of a window 
is coincident with the edge of a wall.

   Second, I managed to create an ADJACENT window between two zones. 
Here are the steps I followed:

1. draw the first zone with a window in one of its walls. Name it "ZONE1"
2. draw the second zone with a window in the wall that is adjacent to 
the first zone. Make SURE that the verticies of the two windows that you 
drew are exactly the same. Name it "ZONE2"
3. hide "ZONE2." Select the ADJACENT wall in the first zone, open its 
"object info" window and set it's construction to ADJ_WALL, its outside 
boundary condition to "zone" and its outside boundary object to ZONE2.
4. select the window in that wall, open its "object info" window and set 
its construction to ADJ_WINDOW and its shading device to ESHADE=0.
5. unhide ZONE2. hide ZONE1
6. follow steps 3 and 4 for this zone (obviously set the outside 
boundary object to ZONE1).
7. unhide ZONE1 and save the *.idf file.

8. open TRNBuild and import the idf file. I got an error saying that it 
was not able to find the ADJACENT windows but when I checked them in 
TRNBuild's zone windows, they were fine. I was able to close and reopen 
the *.b17 file without error.

Kind regards,
  David
