Part 2 in the article series “Inside the Criteria Council”
What does it really mean for an interior design solution to be truly sustainable? As the Criteria Council for Hållbar Interiör (HI) begins its work, the ambition is clear: to create criteria that are both scientifically grounded and practically applicable. One of the contributors to that mission is Derek Diener, researcher at RISE and expert in life cycle analysis.
“It’s not enough for something to feel sustainable – we need to be able to show it. That requires data, methodology, and clear system boundaries,” says Derek Diener.
He is one of eleven members of the newly formed Council, representing the academic and research perspective. For Derek, who has been involved in HI’s development for several years, joining the Council was an obvious choice.
“I believe HI has real potential, and I want to be part of its continued development. I’m also excited to be part of the exchange between researchers, practitioners, and the market – that’s where criteria truly become relevant.”
From Principle to Practice
At RISE, Derek often works at the intersection of research and industry, where sustainability goals must translate into real-world decisions. He sees this experience as particularly valuable to the Council.
“Theory is important, but without practical applicability we won’t get far. My role is to contribute with structure, measurability, and methodology – while understanding when simplification is needed to make things work.”
He notes that compromises are sometimes necessary – that scientific rigor must occasionally yield to usability. The key is striking the right balance: robust enough to build trust, yet simple enough to implement.
Sustainability as More Than a Feeling
According to Derek, sustainable design often lacks clear definitions. A product that appears “green” may have a complex and resource-intensive background, while reused objects might offer significantly lower environmental impact – even if it doesn’t show.
That’s why he believes the HI label should offer decision-makers a tangible reference point. It’s not just about what we choose, but how we plan and design.
“The core message is to keep things in use as long as possible and design for longevity. The most visually impressive solution isn’t always the most sustainable – and HI can help shift that perspective.”
Toward Clarity and Trust
Derek also sees the HI label as a way to reduce uncertainty and increase credibility in the industry.
“Many want to work sustainably, but don’t know how. HI provides both direction and confidence. And with RISE verifying the process, it builds trust – it’s based on facts, not opinions.”
When asked what he’s most looking forward to in the coming work, Derek highlights the opportunity to follow how the label is implemented – and how real-world feedback can help refine the criteria.
“I hope we can encourage more stakeholders to join the label – and keep raising the bar so HI becomes a truly transformative tool for the industry.”
Next Article: Architects’ Expectations In the next installment of the series, we meet Linn Sylvan and Therese Löwstedt, two interior architects on the Criteria Council. What do they expect from the HI criteria – and how might they reshape their work, from the first sketch to the finished space?
