Daylight coefficients
Abstract
The concept of daylight coefficients is introduced, mathematical functions that relate the luminance distribution of the sky to the illuminance at a point in a room. They are illustrated first in the context of standard daylight calculations, and then in the form of finite element matrices. Graphs of the functions enable effects of sky luminance changes to be appreciated qualitatively; use of the coefficients in computer programs gives an efficient method for calculating daylight from a number of sky brightness distributions in succession.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
