The model for surface heat transfer in EnergyPlus is not what you seem to imagine. Trying to assemble an internal reflective cavity using Construction and Material objects does not work. You would need to develop equivalent properties for that portion of the assembly and collapse them into a single Material layer.

i saw many details that they use 3 or 4 metal layers with foam as insulation layers.

Your metal layers are inside the construction and will not do anything to affect thermal radiation. Only the first and last Materials affect the surface radiation properties of the Construction.
