Modest, M. F.

Employing a general numerical model for the calculation of daylighting in interior spaces the sensitivity of daylighting to nonrectangular rooms, such as L-shaped rooms, and to other internal visual obstructions, such as light-shelves, is discussed. In addition, the model has been expanded to allow the treatment of opaque, semi-transparent, and translucent window overhangs, which may be positioned at any or all sides of a window. Further, the model has now the capability of graphical output. Thus, all results are shown in the form of contour plots, showing room outline, sunny areas, and constant-illumination or constant-daylight factor lines.
