Revetec range of luminous flux regulators and remote management with Maestro software


The Municipality of Syracuse, between 2006 and 2007, identified two primary needs:

  • the need to modernize and adapt a significant part of the city's public lighting network, consisting of 13,398 lighting points
  • the need to rationalize energy costs and therefore contribute to reducing management costs, safeguarding the environment.


In the first two years it was decided to focus the interventions, for activities related to energy saving, on:

  1. installation of flow regulators complete with centralized remote control systems;
  2. replacement of lighting fixtures and lamps with others with high performance and luminous efficiency. In particular, at the beginning of the contract, the current state of the systems saw installed about 30% of 250 watt mercury vapor lamps, which were completely replaced with 150 watt SAP lamps.

The savings expected in the offer phase, once the installation of the aforementioned equipment (flow regulators and lighting fixtures-lamps) has been completed, was calculated to be approximately 20% less than the historical consumption before the start of the new management.

Flow regulators installation
It was decided to install about a hundred centralized luminous flux regulators.
To date, the active devices regulate about 65% of the energy used for the operation of public lighting systems in the Municipality of Syracuse.

The average value of the energy savings achieved in the plants where regulators are installed is around 24.3%.
The Reverberi SEC STP range flow regulators are equipped with equipment for remote management of the plants, which is carried out both from the Milan office and locally by the on-site technical staff.

Replacement of lighting fixtures and lamps
It was also decided to install high-efficiency lamps in place of the obsolete Mercury Vapor lamps.


On the basis of the estimates made, it can be stated that in the first contractual year approximately 3% was saved compared to 2002, the year for which consolidated historical data are known; in the second year compared to the first, 25%; in the third year compared to the second, a further 6% is assumed.
In total, energy savings will be about 31% compared to historical consumption before the start of the current management, about 11% more than expected.
This will lead to an expected energy saving of 2,983,558 Kwh, corresponding to approximately a reduction of 695 tons of C0²
