Agreed - exterior balconies are nothing more complicated than shades.
Repeating balconies as seen commonly with multistory apartment buildings & hotels should be defined as typical window overhangs in the wizards of the appropriate dimensions. If it's more of an isolated case you might save time creating a single building shade in detailed edit instead.
Unless the balcony is an extension of the floor slab - at which point it becomes a heat transfer fin. Not too bad if you are in Florida. A wreck if you are in Duluth.
And no, I haven't the vaguest idea of how that is modeled.
In screen 4 of 25 of the DD shell wizard you can specify "Slab
Penetrates Wall Plane" (check box). If you do, eQUEST created a new
wall type of height equal to your slab thickness and composed of 1' of
concrete plus any slab edge insulation you specify on the same wiz
screen. That provides a parallel path for the heat transfer from the
balcony or slab edge. Not exactly 2D heat transfer modelling -- but at
least you aren't ignoring the effect of the slab edge or balcony.
Do you mean an outdoor balcony? I would add a shading device over a window on
the floor below.
