My journey with the EU Data Act began during a fascinating conversation with a colleague at a large automotive company. His deep expertise in automotive regulations sparked my curiosity about how this groundbreaking legislation would reshape our industry. As a software architect, I couldn’t help but dive deeper.
What I discovered was far more than just another regulation—it was a fundamental shift in how we think about data ownership.
One weekend in April 2025, I found myself mapping out connections to the EU Data Act across the industries I’ve worked closely with: automotive, healthcare, and pharma in my previous roles, as well as construction and facility management from earlier in my career. Although the regulation remained the same, its impact varied dramatically across these sectors.
Let me share what I’ve learned.
The Automotive Crossroads
Given my deep involvement with an automotive, this resonates strongly with me.
Modern vehicles are sophisticated data generators. From connected ECUs to detailed telematics, collecting everything from driving patterns to real-time vehicle diagnostics. Until now, we and other OEMs have maintained tight control over this data, citing intellectual property protection and safety concerns.
The EU Data Act fundamentally changes this paradigm: vehicle owners must now have access to their car’s data and can share it with third parties like independent repair shops or insurance companies. This represents a seismic shift for the automotive industry.
I have personally witnessed cases where customers struggled to access their vehicle data after incidents, particularly when trying to understand potential vehicle malfunctions. The automotive industry’s reluctance stems from legitimate concerns about competitive advantage and safety protocols.
Yet, there is immense potential here. Progressive companies are already developing secure data intermediary platforms, creating transparent systems where data usage, consent mechanisms, and service agreements are clearly defined and standardized.
This is where I believe our future lies: building trust through transparent data services.
The Healthcare and Medical Device Revolution
This hits close to home personally since I live with a family member who has diabetes. The daily challenge of tracking blood sugar patterns, diet impacts, and medication effectiveness has shown me how crucial access to medical device data is.
The frustration is real when we see unexplained variations in blood sugar levels, despite maintaining seemingly identical routines. Without comprehensive data access, finding patterns feels like solving a puzzle in the dark.
The EU Data Act brings hope: patients and healthcare providers will have direct access to their device data. Imagine the possibilities: AI-powered apps providing personalized dietary recommendations, predictive analytics for blood sugar management, and real-time optimization of treatment plans.
However, we must carefully balance this with Medical Device Regulation (MDR) and GDPR requirements. These regulations rightly prioritize patient privacy and data security. While the Data Act promotes sharing, MDR and GDPR ensure it happens responsibly.
The challenge lies in creating platforms that prioritize both accessibility and security. As someone who’s worked on medical device software, I understand the complexity of this balance.
Facility Management Gets a Promotion
During a recent work trip to Oslo, I experienced the future of building automation first-hand. My hotel was completely digitized, from check-in kiosks to smart room controls. No human staff, just intelligent systems working seamlessly.
The building’s extensive sensor network tracked everything from motion to energy usage. As an architect, I couldn’t help but think about the untapped potential. Imagine dynamic pricing for services based on real-time energy costs, or predictive maintenance that actually works.
The EU Data Act is a game-changer here: building owners now have a legal right to access their operational data, regardless of who supplied the equipment. This transforms facility management from basic maintenance to strategic asset optimization.
Yet, we must consider existing regulations like the Energy Performance of Buildings Directive (EPBD). While it mandates energy monitoring, it hasn’t historically supported data sharing or innovation.
The Data Act changes everything. Now we can share building data with sustainability platforms, smart city initiatives, and innovative startups. This traditionally behind-the-scenes sector is stepping into the spotlight.
So, What’s the Takeaway?
The EU Data Act isn’t just another compliance requirement, it’s a catalyst for innovation. It exposes both challenges and opportunities in how we handle industrial data.
As someone straddling both technical and business perspectives, I see this as our moment to re-imagine data architecture. We need to bring together legal experts, engineers, and product teams to create new sharing frameworks and challenge existing paradigms.
Let’s continue this conversation. Whether over coffee, at industry conferences or online. Because data isn’t just a by-product anymore, it’s driving our future.
What’s your take on how the EU Data Act will impact your industry? I’d love to hear your perspective.
