Among the three components of daylight affecting a surface's illumination inside a room, the direct component, due to light flux reaching the surface element directly from the sky, (also called sky factor) is the most significant one. Its estimation must therefore be as accurate as possible when assessing the daylighting performances of a building.

Keywords: direct sky component (sky factor) ; luminance ; illuminance ; daylight factor ; daylight modeling
