Energy performance numerical indicators of public lighting

Energy performance assessment for lighting systems is recognized as an important tool for promotion of energy efficient lighting technologies. Based on European directives, components of lighting systems are subjected to eco-design requirements, and lighting systems in buildings are evaluated for energy performance. Now, similar activities are running in the field of public lighting. This paper brings a brief state-of-the art in the standardization process and aims to inform about partial research studies which have to contribute to the preparation of a new European standard.
