This is the answer to the question How much light does the window let in?
Revision 1
As an example, the number of lux indoors cannot be achieved even remotely by evenly distributed sunlight.
It also varies between cloudy and sunny, winter and summer.
It is not just the net area of the window that determines the lightness of the room, but also the height of the lintel. There are several rules, for example, the depth of the room should not exceed twice the height of the lintel.
In addition, different rooms have different requirements.
Our HWR room has enough light at 2 sq. m. by 8 sq. m., our living room has 14 sq. m. of windows by 25 sq. m. – It's nicely light. The children's rooms, with 3 sq. ft. windows per 16 sq. ft. space, are also pleasantly light. The hallway is ~2 sq m, which in cloudy weather is sometimes a little dark.
