[TRNSYS-users] Defining transparent wall

[David BRADLEY]

Martin,
   A few years back, I was faced with modeling some greenhouses that 
were covered by a plastic film. I ended up modeling them as a window in 
Type56 and worked a lot in LBNL's WINDOW5 software to create a glazing 
system that represented the plastic film. The process was no different 
from creating any other new window for TRNBuild/Type56. I wasn't 
entirely happy with the solution in part because of the diffusion of the 
incoming solar caused by the plastic. However, it was the best I could 
do at the time and the results were defensible. At the time, I also 
looked for (and found) some models of actual greenhouses that people had 
developed. None of them suited the project very well but that might be a 
good avenue to pursue as well.
Kind regards,
  David
