After energy performance of lighting in buildings assessed in the proces of energy certification was put to life few years ago, the focus is now on energy performance of public lighting. As required by the mandate of the European Commission to the CEN to define and introduce suitable numerical indicators of the energy performance of public lighting systems, the standardisation process started in 2009. A self standing part of the standard for roadlighting, prEN13201-5 in particular, is devoted to this topic. This standard actually passed through the formal vote in CEN and release of the standard is expected in August this year. Since the begin there were several indicators like LENI, SLEEC and others under discussion, but finally a pair of compound indicators PDI and AECI won the battle. It is obvious that situation in road lighting is principially different from buildings and this fact has to be reflected in selection and definition of the indicators. Aim of this paper is to explain the different approaches and reasons of the selection of PDI and AECI as indicators for assessment of public light ing systems and to give an overview on the main parts of this draft standard with discussion on practical application of the indicators. Lighting control profiles important for calculation of the annual energy consumption incorporated in the AECI indicator are discussed as well in the paper.
