Extending the lighting design objectives procedure for holistic lighting solutions

The author has previously proposed a novel spreadsheet-based lighting design objectives procedure (LiDOs) that enables practitioners to reconcile interacting LiDOs relating to the spatial distribution of illumination within a space, and this procedure has been successfully adopted by several lighting design practices. This paper proposes that the procedure is developed into an extended computer-based lighting design tool (LiDOs2) that includes LiDOs relating to spectral and temporal illumination distributions, as well as spatial distribution. This would enable regulators to specify limiting values for basic indoor lighting objectives such as perceived adequacy of illumination while at the same time guiding practitioners to incorporate LiDOs that address characteristics of lighting chosen to suit specific applications. The LiDOs2 procedure would be capable of generating holistic lighting performance specifications that would enable practitioners to conduct informed searches for light sources and luminaires, and to determine layouts and control circuits with confidence that the specified combination of LiDOs would be achieved.
