DAYLIGHT SYSTEMS
The next step in making daylight decisions is to determine what types of light character will serve the design intent. The controllable aspects of intensity, color, texture, shape and origin are just as valid with daylight as they are with electric light. Daylight systems can be lumped into two basic categories: sidelight and
top-light. We then identify the technologies and geometries that we use to control, modify and enhance each.
Sidelight Systems
Common wall windows are the clearest example of sidelight entering a space. Sidelight systems are unique in the many ways that they can transform daylight into a useful form. If we receive direct sun sidelight, we must consider diffusing techniques like tinting, frosting, and fritting. Sidelighting systems are effective high up on vertical surfaces to impart a glow that lights up ceilings and walls to translate volume. Sidelight systems can also be designed with geometry in mind so that different components of sunlight and skylight are delivered differently through the year. These systems can incorporate overhangs and shelves to shade direct sunlight. Figures 16.7 through 16.1 illustrate various systems for harvesting and controlling sidelight.

Top-light Systems
Most designed spaces have access to high angled downward daylight, regardless of orientation and neighboring structures. Daylight from above can be shaped much like the recessed luminaires we use so much. High daylight is easy to
incorporate into long, linear slots and clean planes. The guidelines for such systems are the same as any daylight:
