Cologne Becomes Germany’s First Smart City with Connected Lighting System from Signify

85,000 lights points in the city of Cologne, Germany, are connected with Signify’s Interact City lighting management system to make the city smarter. The installation is expected to increase the city’s energy efficiency and reduce costs while improve the safety and quality of life of the citizens. The system can also accommodate the integration of sensors into the luminaires, providing data that offer environmental benefits that go beyond lighting. RheinEnergie, which is responsible for the city’s lighting, will replace all the light points with connected luminaires within the next 15 years.

Starting in January 2019, Cologne has converted more than 85,000 public lighting points lighting points to digital and networked lighting via Interact City.

Interact City enables RheinEnergie to continuously monitor and manage all the lights from a single dashboard. This makes planning of maintenance and repairs more efficient and provides RheinEnergie with information and data on the performance and status of the light points for analyses, reports and evaluations.

Additionally, the system enables the integration of sensors on the luminaires, such as environmental data or traffic flows measuring to provide reliable data for sustainable and future-oriented urban development. Thanks to open interfaces (APIs), the system is also integrated into RheinEnergie's SAP system, combining luminaire inventory data with RheinEnergie’s accounting and purchasing data. Signify’s Interact City connected lighting system thus offers cities such as Cologne a comprehensive and stable digital infrastructure for the various public systems and supports their path to becoming a Smart City.
