Numerical patterning is commonly utilized for multifactorial lighting conception, whereas, for elementary conformations, computings can be accomplished by hand, possibly with reference tables. Supported on the locations and mounting altitudes of the habitués, and their photometrical features, the projected illuminating layout can be controlled for uniformness and amount of illumination. For bigger tasks or those with asymmetrical floor projects, illuminating conception software system can be utilized.

Each habitué has its emplacement introduced, and the reflectivity of walls, cap, and floors can be introduced. The software program will then develop a set of configuration graphs covered on the project floor architectural plan, indicating the light degree to be awaited at the functioning altitude. More sophisticated softwares can include the impression of light from windowpanes or fanlights, permitting additional optimisation of the operating expense of the illuminating installation.
