Retrofit of lighting systems have proved to be one of the most cost-effective means of accomplishing energy savings with a minimum of effort dedicated to project design. Many lighting retrofit projects, in fact, are simple one-to-one replacements of lamps and ballasts with more energy-efficient models. The authors have found that it is possible to maximize the energy savings of lighting retrofit projects by utilizing the same approach and methodology as one would for a lighting design project. That is, to use point-by-point calculations to determine exact illumination levels and patterns for both the original fixtures as well as for the retrofit lamp and ballast combinations. Very often one will find that the original design provides excessive lighting levels, even though the present levels may appear to be satisfactory. Point-by-point calculations allow innovation in prescribing retrofits that offer the most life-cycle-cost-effective lighting that is satisfactory to the room`s occupants. Examples of project are provided that illustrate the effectiveness of this approach to lighting retrofit projects.
