Abstract

A computer implemented method for illumination planning is provided that includes providing a floorplan having at least one lighting space; and assigning functions to the at least one lighting space. The lighting space and functions assigned to the lighting space of the floorplan are matched to a historical lighting schema. A lighting layout is extracted from the historical lighting schema and matched to the lighting space. A light package is extracted from the historical lighting schema and matched to the lighting space. A calculation of lighting performance for the lighting layout and the light package that has been matched to the lighting space is conducted to determine whether the lighting performance meets a lighting standard or whether the lighting performance does not meet the lighting standard. The computer implemented method further includes producing a conclusion for the lighting scenario for suitability to the floorplan and functions.
