A staircase provides an opportunity to bring light down into the middle of the house. Because the stair penetrates up through the ceiling and to the second floor, it opens up the ground floor to daylight received from windows and skylights upstairs. Careful placement of stairs, windows and skylights can transform the downstairs experience, and save a great deal of lighting energy besides.
