Yes, EnergyPlus will calculate beam solar radiation entering an exterior
window in a zone and then passing through interior windows in the zone to
adjacent zone(s). It does this by tracking where beam solar radiation
falls inside the primary zone. It will also apportion some of the diffuse
solar entering an exterior window to interior window(s). However,
daylighting through interior windows is not calculated.
