This function computes specular and hemispherical absorptance of each glass pane for exterior irradiation without shading.
It counts the transmittance and reflectance among different panes.
Pane 1 is facing the outside and pane N is facing the room.

extends Buildings.HeatTransfer.Windows.Functions.BaseClasses.partialWindowRadiation;
