I am trying to model a Ethylene tetrafluoroethylene (ETFE) roof with EnergyPlus. Does anyone have any experience using ETFE material with EnergyPlus? Any kind of hint or starting point would be helpful.

What aspects are you unsure about? Drawing the geometry? Accounting for structural edges? Material properties?

Geometry and structural edges are my concerns. and also which E+ object is better to represent the material properties and U-factor? what if I use a three layer cushion? How can I differentiate them from the simple glass in terms of long wave radiation?
