Daylight factor - Wikipedia. In architecture, a daylight factor (DF). It is defined as: DF = (Ei / Eo) x 1. 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: Direct light from a patch of sky visible at the point considered, known as the sky component (SC),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). The sum of the three components gives the illuminance level (typically measured in lux) at the point considered: Illuminance = SC + ERC + IRCThe daylight factor can be improved by increasing SC (for example placing a window so it . In most rooms, the ceiling and floor are a fixed colour, and much of the walls are covered by furnishings. This gives less flexibility in changing the daylight factor by using different wall colours than might be expected. Undertaken using the IES Radiance software Module. Architects and engineers use daylight factors in architecture and building design to assess the internal natural lighting levels as perceived on working planes or surfaces.

They use this information to determine if light is sufficient for occupants to carry out normal activities. The design day for daylight factor calculations is based on the standard CIE overcast Sky for 2. September at 1. 2: 0.

It uses ray tracing to perform all lighting calculations. One failing in many of these calculations is that they are often completed without wall hangings or furniture against the walls. This can lead to higher predictions of the daylight factor than is correct. In the UK this is likely to be CIBSE Lighting Guide 1.
