Danish window and door manufacturer builds internal expertise to automate EPDs and reduce dependency on consultants
Vindunor is a Danish manufacturer of high-performance windows and doors supplying the Nordic construction market. The company’s product range is widely used in both residential and commercial buildings where durability, energy performance, and aesthetic quality are key.
As sustainability requirements expand across Europe, Vindunor is aligning its business strategy with the growing need for transparent and verified environmental data.
When Danish construction regulations began requiring documented carbon data, Vindunor quickly recognized that Environmental Product Declarations (EPDs) would become essential for market access. Initially, however, the company relied heavily on external consultants to produce EPDs.
“Before, we depended on consultants for every single EPD. It worked, but it wasn’t scalable — and we had very little internal insight into how the results were calculated.” – Anders Jensen, Sustainability Manager, Vindunor
This dependence created both cost and operational challenges. Generating new EPDs or updating existing ones could take months, limiting Vindunor’s ability to respond to customer requests and tender requirements.
“We wanted to understand the process ourselves and not have to wait weeks for updates or changes. It was important for us to have control of the data and to build our own knowledge”, says Anders.

Vindunor decided to invest in an in-house workflow for creating and managing EPDs. The aim was to enable internal staff — rather than external consultants — to produce verified environmental data for their full product range.
“We wanted our team to be able to handle EPDs independently, from data collection to publication. Once you understand the logic behind it, it’s actually manageable,” Anders said.
Using automation and standardized datasets, Vindunor established a process that integrates EPD generation into their daily operations. This gave the company full visibility over data inputs and assumptions, ensuring each declaration reflects the latest production information.
“Automation helped a lot,” Anders noted. “Now we can update data when production changes without starting from scratch. It saves both time and resources.”
A key factor in Vindunor’s success was the structured onboarding process and continuous technical support. Instead of relying solely on documentation, Vindunor’s team received hands-on guidance that accelerated their learning curve.
“The onboarding was really good,” Anders recalled. “We got help step by step, and we could ask questions at any time. It felt like there was always someone there to make sure we were doing things right.”
This combination of personal support and self-paced learning allowed the team to become confident users in a matter of weeks. As Anders emphasized, it wasn’t just about learning how to use a tool — it was about understanding the underlying principles of life-cycle assessment.
“It’s not just about clicking the right buttons,” he said. “The training helped us understand the logic behind EPDs — what the data means and how to interpret it correctly. That’s what makes it sustainable in the long term.”
By the end of the onboarding process, Vindunor had a repeatable internal workflow and the confidence to scale EPD production independently.

The shift to in-house EPD creation has delivered immediate efficiency gains. Vindunor can now publish EPDs much faster and respond quickly to customer or project-specific data requests.
“We’ve reduced the turnaround time dramatically. What used to take months now takes days,” Anders said. “It also costs less — and the quality is actually higher because we know the data and how it’s structured.”
Bringing EPD expertise inside the company has also strengthened Vindunor’s sustainability culture. Engineers, designers, and management teams now share a common understanding of carbon impacts and how design decisions affect environmental performance.
“The biggest advantage is knowledge,” Anders summarized. “By doing it ourselves, we learn every time. That’s something we would never get by outsourcing.”
Vindunor plans to expand its EPD coverage to include new product ranges and variants. The company views in-house EPD management not only as a compliance requirement but also as a strategic advantage for future growth.
“Our customers increasingly ask for documentation,” Anders said. “Being able to deliver reliable data quickly gives us credibility and strengthens our position in the market.”
