Environmental and Energy Performance of Public Lighting Installations: Results of a Measurement Campaign

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 has been 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 was 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 and energy performance.
