Of course, glass will have to be double-glazing otherwise heat will escape and you will not see the benefits of the steps you took. In addition to this, light shelves bounce light into a building and they can be incredibly effective. From the floor to the top of the window, light shelves can bring light into a room two and a half times this distance.
Also, you could use clerestory windows which are long, thin panes that sit just under where the wall and ceiling meet. With a roof overhang in position, light will be allowed in whilst being protected from the sun. Finally, light tubes are also an option as they amplify any low-level light. By utilizing special lenses, sunlight enters a highly reflective tube and, through a diffuser, projects into a living space with even distribution.
