[TRNSYS-users] Multiple Wingwalls

[David Bradley]

Mohannad,
  If I am understanding your configuration correctly, you have a large 
west facing facade that has vertical fins projecting perpendicularly 
every 2 meters? If this is the case, you can think of the facade as a 
series of 2m sections all of which are identical. So you could define a 
Type34 for the repeating section: width 2m, height 3m each with a left 
and a right wingwall that projects 1.8m. Type34 calculates solar 
radiation per unit area on the facade so you can then apply its 
calculated result to the entire 18m x 3m facade. If you wanted to be a 
little more rigorous, you could define two Type34s, one for the opaque 
part of each 2m wall section and one for the transparent part. If you 
are using Type56, you would then have to define your windows in the 
"additional windows" category so that they can have a different 
ORIENTATION name than does the wall. Recall that all an ORIENTATION 
means in TRNBuild / Type56 is that a certain amount of radiation per 
unit area falls on all surfaces having that ORIENTATION.
Best,
 David
