Sunlight, skylight and design

Non classé

Sunlight is a very intense directional light which comes from a point source of light (a ‘beam’),the sun. It cast sharp shadows. The intensity of a beam light varies with the day time, the season and the location on planet. It generally creates a warm color of light (candlelight color at sunrise and sunset ; neutral white at noon)

Skylight is a multidirectional light, more diffused (or scattered) arriving from a large area of light. It doesn’t cast a distinct shadow.It includes the light from clear blue skies (non uniform, cool color) and cloudy skies (uniform, half way sunlight and clear blue)

Local climate (proportion cloudy days / clear blue days + proportion beam sunlight / scattered skylight) determines the illumination available from sky lighting.
