Hi @mikeheiss ,
Yes, the window conduction term in Honeybee accounts for both the conduction that happens as a result of indoor/outdoor temperature difference as well as solar heat that gets absorbed by the glass and conducts to the interior. The solar term that you see in Honeybee accounts for only solar that is directly transmitted through the glass (and then absorbed by interior surfaces). And, yes, solar heat hitting opaque walls that then conducts to the interior will be included in the Opaque Conduction just like Window Conduction.
Still, I sense there’s a slight misunderstanding in your descriptions:
Note that the SHGC metric includes BOTH directly transmitted solar gain as well as solar heat that gets absorbed by the glass and then conducts to the interior under standard “summertime” thermal conditions. I think the term you are looking for is “Solar Transmittance” and not “SHGC” since Solar Transmittance refers exclusively to the fraction of incident solar heat that does NOT get reflected or absorbed as it passes through the glass.
