London Borough of Haringey, UK by Urbis Schréder

The roll-out of a Central Management System for the London Borough of Haringey’s 25,000 street lights has won both a GOLD and GREEN Build Back Better Award in the 2023 lighting category.

The local authority selected the cloud-based EXEDRA platform from Urbis Schréder to optimise energy use and configure the street illumination at a local level in real time. 

It follows the publication in 2021of ‘Haringey Climate Change Action Plan’ to deliver a route map towards Net Zero Carbon for the council by 2027 . Haringey has been a leader in carbon dioxide reduction and in its work on climate change. The borough is on target to deliver its 40 per cent carbon reduction by 2020 from its 2005 baseline. It has a better performance than neighbouring authority areas, but this strategy looked a how additional carbon reductions could be achieved whilst putting its residents and communities first.
Haringey is responsible for around 25,000 street lighting assets, and as part of its ongoing commitment to energy conservation and carbon reduction completed a six-year programme to upgrade these to LED. Significant energy savings of around 60 per cent had already being realised, however in order to provide additional connectivity and control to better meet future community and resident needs Haringey sought suppliers to provide a Central Management System (CMS).
Following a formal tender process in 2021, the Exedra platform solution from Urbis Schréder was selected and the deployment commenced in September that year.
Unlike traditional CMS solutions, Urbis Schréder’s EXEDRA platform is cloud native, microservice and serverless, utilising the functionality and tools of Microsoft Azure IoT. It is built as discrete services that are independently deployable, which means it has the ability to scale independently, giving more flexibility in updating individual subsystems and providing the flexibility to choose appropriate technology on a per subsystem basis. In addition it is certified TALQ compliant, both at a Gateway and CMS level, providing a foundation for future connectivity and services.
Lanterns and other devices are connected via cellular nodes, which allows larger amounts of data to be transmitted to and from the deployed devices, thus enabling real time and live communication and facilitating over the air software and firmware updates to help ensure end-to-end security of the solution over the lifetime.
The initial benefit of the new technology is that the lighting is now responsive and adaptive to help deliver the right light in the right place at the right time for the user and task being carried out.

For instance, if Tottenham Hotspur is playing at home, lighting can be increased to full output to help visitors and residents get home safely.

Energy savings of up to 60 per cent have been achieved in some areas with the new platform while still meeting best practice in BS5489. More importantly there was no negative feedback from the community during this time.
Unlike proprietary systems, EXEDRA is based on the Microsoft Azure IoT system and is certified TALQ compliant, both at a gateway and CMS level, providing a foundation for future connectivity and sensor-based services.
