On 24 June 2026, the WeForming and DECODIT consortia came together for a joint technical workshop.
The meeting focused on technical alignment and collaboration within the framework of Common European Energy Data Spaces. The primary ambition of this collaboration is to move away from today’s fragmented data ecosystem and establish a fair, standardised, and secure framework for exchanging data. This structure ensures seamless interaction between data owners and data users, including building owners, citizens, energy service providers, and electricity grid operators.
Why Is Europe Pushing for Unified Data Spaces?
The European Union’s drive towards unified data spaces is centered around three core principles:
Data Sovereignty: Moving away from unregulated data sharing to guarantee that users keep full control over their own data under clear, transparent rules.
Value Creation and Monetisation: Enabling citizens and businesses to safely share energy metrics and receive tangible financial rewards or enhanced services in return.
Innovation at Scale: Making data sharing easier to foster the development of next-generation green energy businesses and innovative digital tools.
To prevent technical fragmentation caused by incompatible technologies – such as completely separate setups for home heating systems, heat pumps, electric vehicles, and solar panels – both projects are actively building towards a unified framework or smart middleware.
Turning Messy Building Data into Intelligent Decisions
Real-world buildings suffer from unique data challenges, including broken streams, missing information, or hardware connectivity issues. The workshop highlighted the structured workflow required to transform this raw, messy data into high-value operational insights:
- Information Layer: Raw hardware streams are combined with essential metadata and time-stamps to make the data actionable.
- Knowledge Layer: Data is structurally mapped using open international standards and ontologies to create a clear semantic model.
- Wisdom Layer: Automated control tools or third-party energy experts use this unified data pipeline to make optimal energy management decisions for the end-user.
Addressing Stakeholder Demands and Pilot Challenges
During the workshop, partners evaluated how data spaces directly answer the distinct demands of modern energy stakeholders:
Building Owners and Citizens are looking for automated energy recommendations to lower their utility bills via user-friendly apps. They are less interested in the technical data space itself and more focused on the automated microservices it enables.
Service Providers require secure access to building-level data to offer advanced energy flexibility and efficiency optimization services.
Grid Operators (DSOs) are highly interested in consumer consumption trends to handle frequency regulation and improve peak demand forecasting.
While technical challenges remain – such as managing high seasonality when properties are empty for parts of the year, or handling home router changes that interrupt data streams – the projects are deploying robust, plug-and-play hardware and compression solutions to keep data flowing reliably.
A Powerful Technical Synergy
The collaboration bridges a crucial technical gap in the European energy ecosystem. While one project operates primarily at the higher system, district, and aggregation layer, the other drills deeper into individual buildings, private homes, and local appliances.
Connecting these two approaches creates a highly complementary, end-to-end network pipeline. By demonstrating a sovereign and secure exchange between their federated data spaces, WeForming and DECODIT are paving the way for a more collaborative and sustainable European grid.
