Dear Pauline, Ntype 931 doesn’t
include shading effects, thus it should bet he same as type15-6 output “total tilted surface radiation”. For checking whether the SHM
is used please check - NTYPE 101 OSHADB Total
shading factor of external window for direct radiation incl. geometric shading - NTYPE 102 OSHADD Total
shading factor of external window for diffuse radiation incl. geometric shading or - NTYPE 103 IBSHAD - NTYPE 103 IDSHAD Concerning the shading
matrix: 99 -> sun is behind
the window no shading 0.... 1 -> sunlit
fraction (0 ... shaded, 1 ... sunlite (no shade)) The hemisphere is divided
into patches acc. to the tregenza model. In the attached file
includes the patch number, the zenith and azimuth angle for the centre point of
the patch. Best regards, Dipl.-Ing.

[mailto:p.gelin@katene.fr] Dear all, I still have encountered problems with the shm file, coming from my
trnsys3d drawing, and now the results of my simulations in trnsys17 studio. To check if shm file was really used I compared for a window
which normally has shading from buildings around it, like 2 wingwalls : - the trnbuild output n°931 “total external solar radiation on
external windows including frame” - the type15-6 output “total tilted surface radiation” I noted no difference ! So that means simulation didn’t take account of wingwalls drawing
in trnsys3d. So I read the shm file with a notepad. I understood that each column represents a window and when there is
0.99 there is no radiation on it. But what represent the 576 lines (not the hours, days, months or angles
?) ? And above all, how are the other fractions used ? Thanks a lot for everyone who could explain me that. Best Regards, Pauline Gelin KATENE engineer mailto:p.gelin@katene.fr FRANCE |
