A Urban Lighting Renovation Project to Optimize Environmental Performance and Reduce Energy Consumption: Results of a Measurement Campaign

In the last few years, the need to reduce costs and to limit energy consumption, together with the availability of financial and carbon reduction incentives led many public authorities to undertake the renovation of public lighting installations. In the North of Italy, a major program of public lighting renovation is being implemented in Torino since 2015. To verify the effectiveness of the interventions, the performance of the new LED lighting systems compared to the previous installations were assessed through measurement campaigns and computer simulations. The paper presents the main features of the project, the methodology adopted for the performance evaluation campaign and the results obtained in terms of both lighting performance (measured luminances and illuminances over representative areas) and energy performance (calculated Power Density and Annual Energy Consumption Indicators as defined in the EN 13201-5:2015).
