EDI-Net at a glance

The EDI-Net (Energy Data Innovation Network) initiative analyses and communicates sub-hourly electricity, gas and water smart meter data to identify waste and savings opportunities, reduce consumption and save money. The initiative is aimed at public authorities’ decision makers, financial planners, energy and building managers and building users. An online forum and workshops facilitate the sharing of knowledge, experiences and best practices to support public authorities during the implementation of their sustainable energy and climate action plans.

EDI-Net helps municipalities to save water

For some time now, our three pilot cities have been using the various EDI-Net tools to continuously monitor and optimize their energy and water consumption. Alexander Nordhus, Energy Manager of the City of Nuremberg, explains how this can uncomplicatedly and quickly uncover waste: “As Energy Manager you have to keep an eye on the energy consumption of many buildings. Since the number of caretakers has decreased recently, it is all the more important to be able to quickly identify excessive external resource consumption.

At the beginning of May, the daily routine of checking all smiley faces for two meters revealed an unusually high water consumption. One of the buildings is a large school of more than 10,000 m2, the other is a residential home for homeless with a living space of about 3,000 m2. The responsible caretakers, who were not aware of the high consumption levels at the time, were informed. In the men's hostel, the cause was quickly discovered: a hose used to fill a garden pond with water had not been turned off after the pond was full. As a result, water was continuously flushed into the garden and seeped away.

At school the search for the cause took longer. On the occasion of a special school event, the toilets were set to continuous operation so that they were flushed every 30 minutes, 24 hours a day.

Without EDI-Net, the error would probably have been detected only by accident, which in our experience could have taken up to three months. All in all, EDI-Net contributed in both cases to save more than 1,300 m³ of water - and thus around 6,700 euros!”

EDI-Net Policy Paper on Smart Meter Regulation Requirements for Municipalities

It is now widely accepted that frequent data measurement is critical to reducing energy and water wastage. Leaks and other defects can be detected more quickly and building systems can be programmed as needed. Data can also be used to raise awareness, as is currently happening as part of the EDI-Net project. Current EU legislation is based on a simple relationship between customers, meters and utilities. However, this is often not the case in municipalities where central energy departments manage a large and diverse portfolio of buildings - often with their own energy contracts.

EDI-Net has now shown that municipalities have limited access to smart meter data for their buildings. Even in countries where the introduction of smart meters is already well advanced, it is often not possible in practice to improve energy efficiency. In Spain, for example, short-time meter data is only made available at the end of the month and it is not possible to react quickly to excessive energy consumption. In Great Britain, "transparent procedures" for data exchange could not be enforced with complaints to the settlement agencies, and in Germany interoperability with energy management systems is limited. In France, it remains difficult to obtain approval for access to measurement data by more than one authority. This list can certainly be continued in relation to other EU countries.

A closer look has also revealed: Municipalities that "lead by example" to increase the energy efficiency of their building stock through information and communication technology face increasing difficulties in accessing the data they have had access to for years. When suppliers install smart meters, they regularly disconnect customer access from the old meter and municipalities can no longer monitor the building unless they invest a second time. Other problems also arise from the inadequate definition of smart meter devices and standards, leading to the introduction of devices whose functionality does not match the capabilities of existing AMR hardware.

In order to meet EU energy efficiency targets, there is a need for a more coordinated development process for the introduction and operation of smart meters in municipalities. Above all, a targeted communication strategy should accompany the way, and this means that all stakeholders must be involved in a cross-sectional way: both the legislature and the local authorities and departments, as well as the building users, who can only demonstrate more energy-efficient behaviour by raising awareness of the issue.

Exciting exchange between municipal representatives at workshops in Leicester and Nuremberg

In June and July, EDI-Net workshops in Nuremberg and Leicester brought together representatives from German and English municipalities to discuss strategies for improving energy efficiency. The energy managers of the pilot cities showed how they use EDI-Net in their daily work to quickly and easily detect waste of water and energy. The results implemented by the environmental schools in Leicester with the help of EDI-Net are particularly exciting: even primary school pupils are concerned with the smileys that show them how much energy and water they consume and are therefore more resource-friendly. Students now pay more attention to close the windows while heating or turning off the light when it is no longer needed.

Would you like to know more about this topic? On 03 October 2018 from 12.30-04.00 pm (BST) the workshop "Energy Management in Schools" will take place in Leicester, Great Britain. The event is free of charge. To book a seat please write to or as soon as possible.

Connecting Cities ‒ Local Solutions for Global Challenges

1 – 3 October 2018 | Barcelona, Spain
Together, we can better decouple our production and consumption systems from natural resource depletion while tackling climate change, enhancing resilience, easing social tensions and diminishing financial instability. Our cities and towns are already co-creating solutions to these challenges. Every day, local authorities are implementing innovative approaches to governance that facilitate new coalitions and networks for more just, sustainable and resilient societies.

Connecting Cities strengthens network-based approaches to global challenges by connecting local and regional authorities from across Europe. Together, we can transform challenges into solutions! More information here.
