Abstract

This paper describes a large-scale energy efficiency assessment of the public lighting system in the city of Cuenca, Ecuador, carried out with the collaboration of the system administrator, the Central South Regional Power Company (CENTROSUR). For the evaluation, the Spanish regulation ITC-EA-02 and the European standard UNE-EN 13201 were used since there are no similar efficiency standards in Ecuador. Three thousand measurement points distributed on about 200 city roads were surveyed. The results allowed to evaluate the levels of average horizontal illuminance on the road and the mean and general uniformities of the arteries as well as the energy efficiency during the years 2014-2015. As a conclusion, and according to the aforementioned European regulation, 81% of the studied roads have excessive levels of illumination; 13% deficient levels and only 6% of the roads complied fully with the standards.
