RE: [EnergyPlus_Support] problem with thermal radiation

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.

Hi,
I investigate on thermal radiation and its effects
I have two alternative materials
1- external wall ( with two metal layers)
2- external wall2 (with out metal)
The difference between two simulations  was very poor and thermal radiation energy loos by the wall that has this material wasn't change.
