I struggled with lighting interiors as well. What sort-of came out of that was someone mentioned the use of portals as a means to 1) cut down on render times, since light rays travelling out the window don't really need calculating, and 2) checking your ambient occlusion distance settings in the World settings. Not sure if that helps, but just saying: I relate to your frustration.
