Economic Efficiency of City External Lighting Systems: Methodological Research

The article reveals the methodological tools for research and assessment of the economic efficiency of the functioning and development of outdoor lighting systems in cities. The purpose of the research in the work is to substantiate approaches and methods for assessing efficiency, establishing types and groups of efficiency criteria, as well as developing a system of performance indicators for outdoor lighting systems. Taking into account the nature and purpose of the research object, the authors propose to make a comprehensive assessment of its effectiveness based on three groups of criteria through indicators of socio-economic, technical-economic and financial efficiency. In order to ensure comparability of efficiency indicators assessment of heterogeneous outdoor lighting systems, the work substantiates the new concept of “conditional luminaire”. The methodological research tools proposed in the work can be used by owners in making decisions on the expansion, reconstruction, and modernization of outdoor lighting systems.
