Is it necessary to adjust the albedo boost and indirect intensity?

I'm working on a interior design visualization in Unity but the problem is some rooms are too dark even the directional light is direct to the window of the room is still dark. I know the solution is adjusting the albedo boost and indirect intensity. But is this the right way by adjusting the albedo boost and indirect intensity? Because I want to achieve a realistic result

Note: I'm using Realtime GI without mix lighting because I want to achieve Day/Night Cycle.
