Externally reflected component

WebExternal Reflected Component (ERC): Sunlight reflected from an exterior surface (building/walls) and then reaching the point considered, known as the externally reflected component (ERC). Light reflected from an exterior surface and then reaching the point considered, known as the externally reflected component (ERC), Light entering through the window but reaching the point only after reflection from an internal surface, known as the internally reflected component (IRC). See more In architecture, a daylight factor (DF) is the ratio of the light level inside a structure to the light level outside the structure.

External Reflection: Fresnell

WebNote that when light hits a surface, part of it is reflected back. This reflection normally takes the form of diffused (nondirectional) light and is dependent on the object's reflection. The reflection of the outside ground is typically on the order of 0.2 or 20%.
