I'm trying to get IEQ C8.1 by the prescriptive option, but I'm having problems with the calculation of the window areas.

Its a residential building and the project contains plenty of balconies and not much windows. Could I consider the areas of the glass doors from the balconies? To calculate these areas, should I use the window head height minus 30 inches or the height of the balcony's sill? And the obstruction of the ceiling of the balcony, should I use the 63-degree angle from the vertical to modify the height?
