RT Journal Article T1 Maintenance factor identification in outdoor lighting installations using simulation and optimization techniques A1 Ogando Martínez, Ana A1 López Gómez, Javier A1 Febrero Garrido, Lara K1 3306 Ingeniería y Tecnología Eléctricas K1 3306.04 Iluminación Eléctrica AB This document addresses the development of a novel methodology to identify the actual maintenance factor of the luminaires of an outdoor lighting installation in order to assess their lighting performance. The method is based on the combined use of Radiance, a free and open-source tool, for the modeling and simulation of lighting scenes, and GenOpt, a generic optimization program, for the calibration of the model. The application of this methodology allows the quantification of the deterioration of the road lighting system and the identification of luminaires that show irregularities in their operation. Values lower than 9% for the error confirm that this research can contribute to the management of street lighting by assessing real road conditions.
