[EnergyPlus_Support] Greenhouse plastic film optical properties

["jvd2pe" <jvd2pe@xxxxxxx>]

Dear Support Group,
I'm working on a simulation of a greenhouse which operates primarily
during the heating season in Michigan, USA and is covered completely
by a double layer of plastic film.  The film is inflated by a fan
pumping air into the space between the layers.  I have obtained
optical properties from the film manufacturer for Transmission, Haze,
and Clarity per ASTM D 1003.  I do not know much about fenestration
properties, and want to know how to tell EPlus appropriate values for
the Material:Windowglass, since the fenestration has a huge impact on
the simulation.
Have any of you got experience with providing or creating these values
for greenhouse films?  (Thanks in advance!)
