Diffuse transparent media

Postby wariner » Thu Feb 16, 2012 12:38 pm

Is there a way to model materials that are diffuse as opposed to completely transparent?

Examples include polycarbonate panels used in warehouses, or Sunoptic rooflight diffusers.

Many thanks

Bump. Same question. There seems to be almost no option in IGBD (database) for translucent materials.

EnergyPlus does have an option to make a glazing material (solar diffusing) according to the InputOutputReference (page 146/2234).

Is there a way to expose this in the DesignBuilder interface?

Another bump. Is there a way to externally load this at simulation using the "Include idf File" option? Seems like a lot of work for a simple yes/no toggle.

Another Bump to this question.

I hope someone is going to answer!
