[TRNSYS-users] Shading matrix just for some windows

[hotline]

Hi Toni,

Well, the shading matrix contains only windows which are actually shaded.
The limitation of 100 is related to formatted printing issue only.
Did you try to generate the matrix?
If it fails you may send me your project for further debugging (hotline at transsolar.com). As I mentioned before we are currently revising this process.

So I would like to ask you if there is the possibility to keep the 200 windows but to generate the shading matrix just for these 50 windows. Is it possible?

Well, yes but it is more work you can do the following:

  *   Export the b18 to TRNSYS3d file
  *   Open the trnsys3d file in the SketchUp plugin Trnsys3d
  *   Delete the windows which aren't shaded
  *   Save as a modified T3d file
  *   Open this modified T3d file in TRNBuild and generate the matrix.
  *   Copy the generated *.shm to the folder of the original b18 file and rename it such that name as the original b18 but with the extension "shm"

Since the geometry and the surface IDs are the same for the original B18 file and the modified one with the reduced number of windows the shading matrix is correct for both files and can be used.

Kind regards,

Marion

Betreff: [TRNSYS-users] Shading matrix just for some windows

Hi everybody,

I am modelling a huge building with ca. 80 thermal zones and almost 200 windows. I can not merge the windows and I know that, in case the number of windows is higher than 100, TRNBUILD is not able to generate the shading matrix.

Of these 200 windows, the shading matrix could be relevant just for 50 windows (windows with balconies). So I would like to ask you if there is the possibility to keep the 200 windows but to generate the shading matrix just for these 50 windows. Is it possible?

If not are there others alternatives (that are not merging windows or split the building model in two/three building models)?

Thanks a lot
