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.<br>
Kind regards,<br>

<div dir="ltr">Hello there,<br>
<br>
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?!<br>
<br>
Thanks <br>
