Citelum and Paradox Engineering work to make Siracusa, Italy a 'Smart City'

March 2, 2017 - Siracusa is a historical City located in the southeast corner of Sicily, Italy, with a population of around 125,000 people. It is very well known for its rich Greek cultural and artistic legacy, as UNESCO listed it as a World Heritage Site along with the Necropolis of Pantalica. Committed to sustainable growth, the City is building its own future by investing in smart technologies to improve urban services, increase energy efficiency, simplify internal processes and encourage citizens’ participation.

In February 2015, the City launched the “Siracusa SmaRt” project and called for tenders to renew the existing public lighting infrastructure with LED-based devices, also developing a remote control and data transmission system. Citelum and EBF Costruzioni Impianti won the contract by proposing a true Smart City project for the small island of Ortigia, representing the heart of Siracusa’s historical center. Citelum’s project was designed to achieve four main targets: energy efficiency, city beautification, remote control and management of lighting points, data transmission systems. Data transmission systems were aimed at citizens, tourists and the municipality, leveraging Internet of Things (IoT) technologies to deliver broad- and narrowband communications thus enabling several services as video surveillance, WiFi hot-spots, tourist information, measuring and sensing.

Citelum replaced about 1,530 lighting points with energy efficient LED lamps, that is old-fashioned artistic lanterns with warm white lights to enhance buildings’ and monuments’ colors. Choosing Paradox Engineering’s wireless network platform to enable remote management and control, each luminaire is now connected to an urban-wide network and can receive and transmit data and execute commands.

Thanks to Paradox Engineering’s technology, Citelum can remotely manage breakdowns, plan maintenance routines and set customized lighting patterns for single districts, streets and even single lamps, triggering on/off and dimming actions according to programmed schedules (ie. daily solar times, week days, specific local circumstances or events, etc.) or on demand (ie. in case of emergencies or public security issues).

This step was completed in less than two months, paying peculiar attention to some of the City’s most ancient locations and monuments such as Cathedral Square, the Arethusa’s fountain, and Saint-Joseph Church. The Smart Lighting solution has been operating since December 2015, and the City expects a reduction of power consumption up to 60% in selected districts.

In a genuine Smart City spirit, and taking advantage of Paradox Engineering’s Internet of Things-ready platform, Citelum used the same wireless architecture to support further devices and provide citizens and visitors with additional urban services.

Video surveillance is currently granted through 10 IP cameras located in Ortigia, while 2 variable message panels offer useful traffic guidance and 3 digital boards display tourist information. Moreover, Paradox Engineering’s platform enabled a pilot Smart Metering project, connecting 12 electrical meters to the network for remote reading and energy consumption control.

A further step was made in July 2016, offering people free Internet access through 26 Wi-Fi access points, all installed in Ortigia leveraging existing Paradox Engineering’s smart devices without the need to implement a different network.

With the “Siracusa SmaRt” project, Citelum has thus started to build a real smart urban network, hosting a number of applications over the same wireless infrastructure. More services might be integrated in the future according to specific urban needs and available resources: next steps might include for instance the development of a Smart Parking solution to monitor public lots and facilitate parking search, possibly extended to electrical vehicle charging stations to support green mobility.
