Re: [TRNSYS-users] Defining transparent wall

[David BRADLEY <d.bradley@tess-inc.com>]

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

Hello there,

I am using TRNSYS 16 to estimate the total cooling requirement of three temporally built structures. One of the structures is a tent whose vertical walls contain like 50 percent plastic transparent parts. How can i create a layer and define it to be transparent to the incoming radiation?? I know that this must be having a huge effect on the total cooling requirement. Can someone please help me with some ideas how this can be done?!

Thanks
Martin
