+The important distinction between this output variable and those for ``Surface Window Heat Gain/Loss'' is that this represents the net heat flow through the window and not the heat flow \emph{to the zone}. The only difference is the heat flow \emph{to the zone} does not account for radiation from the opaque frame and divider components.
