Direct sunlight should be diffused and controlled; Skylight is welcomed and easier to put to use;
Study of solar geometry and diffusing materials are the key to good daylight textures.

controlling Top-light.

LIGHT CONTROL TECHNIQUES
The last ingredient to making use of daylight is an understanding of the technologies that we use to alter the light textures we receive.
Diffusing
Diffusing daylight can be accomplished through the use of translucent acrylic, frosted glass and a host of other slightly opaque materials. This treatment tends to create a soft, even texture similar to skylight on a cloudy day.
Tinting
Tinting is the simple act of reducing the transmittance of a transparent substrate. Tinting films and laminates come in a variety of colors and are often mirrored. In many cases they receive mixed reviews as they impart a strange sort of gloomy or dark perception of the outside world.
Fritting
Fritted materials are otherwise transparent materials with lines etched or embedded in them. Good fritting can act like a series of miniature light shelves or louvers, using geometry to reduce the transmission of light at certain angles. Bad fritting behaves similar to diffusing materials or prismatic lenses.
Daylight at Work
There are, of course, situations where the raw, unbridled effects of natural
daylight are exactly what a space needs. When daylight is used as an accent feature, the challenge is often in studying exactly what type of system is most effective. Daylight for the sake of energy conservation is a noble cause, but there are just as many valid emotional and experiential reasons to work daylight into your design. Many of the most amazing natural and designed spaces hang much of their greatness on the inclusion of daylight. The ethereal connection we hold with daylight makes it a powerful ingredient that can turn an otherwise sterile environment into a truly moving experience.
