Daylight factor
In architecture, a daylight factor is the ratio of the light level inside a structure to the light level outside the structure. It is defined as: DF = (Ei / Eo) x 100% where,Ei = illuminance due to daylight at a point on the indoors working plane,Eo = simultaneous outdoor illuminance on a horizontal plane from an unobstructed hemisphere of overcast sky. To calculate Ei, requires knowing the amount of outside light received inside of a building. Light can reach a room via through a glazed window, rooflight, or other aperture via three paths: Lux = SC + ERC + IRC
