Consto and Siva built the world’s northernmost BREEAM Outstanding certified building
Consto and Siva have realised a groundbreaking innovation center in Tromsø – the world’s northernmost building with a BREEAM-NOR Outstanding certification and a record score of 99.2%. Interaxo was the project's digital backbone, assisting their vision, precision and collaboration to set the standard for sustainable construction projects – both in Norway and internationally.
Stage 4 at the Research Park in Tromsø has set a new standard for sustainable construction – both nationally and internationally. With a BREEAM-NOR Outstanding certification and a record score of 99.2%, this is not only Norway’s first building to achieve such a goal; it is the world’s northernmost building with the ‘Outstanding’ status.
“You can’t achieve such a high score if the project isn’t planned for sustainability from the outset.”
– Ida Bordi Stene, project manager and BREEAM manager at Consto
Ida has had a central role as BREEAM AP, with responsibility from design to execution – a role she has held for three years. “Such an ambitious project requires more than just good intentions – it requires structure, overview and a platform that ensures accountability and interaction,” she shares.
The solution was Interaxo and the BREEAM module
Interaxo was chosen as the digital platform for the project, and the BREEAM module was tailored to the needs of the project. Ida had previous experience with Interaxo and highlights several advantages: “It’s a big plus that we could get the modules tailored. We could easily extract data in Excel, customise the documentation flow, and gather everything in one place.”
The documentation in BREEAM is divided into the engineering phase, design and completion. With the help of Interaxo, folders and workflows were created to support the entire process. All documentation was gathered and followed from start, through revision and to final approval. “Everything is so well sorted that if you need to replace a person, everything is still there. What if you had used email instead? That would be horrible,” Ida says with a smile.

A demanding project – and an award-winning result
The project has been both demanding and unique – not only because of the level of ambition, but also because of the location in Tromsø and unforeseen events along the way, such as the bankruptcy of subcontractors. Nevertheless, the project managed to deliver on time and on target, thanks to good collaboration between Consto and Siva, and not least a clear sustainability strategy. Ida asks the rhetorical question: “What is an innovation center without innovations?”
She emphasises that Interaxo made it easy to share findings, reports and feedback – and that it facilitated good interdisciplinary collaboration. In May 2025, the project was awarded the prestigious BREEAM Award for New Buildings, with the jury stating that the building set a new standard for BREEAM-NOR certification in Norway.
Key figures from the project:
- BREEAM-NOR Outstanding with a score of 99.2% – top 6 globally
- One of only 69 projects in the world with innovation points
- 45% reduction in greenhouse gas emissions
- 65% reduction in water consumption
- 98.3% waste sorting rate
- 23.8 kg waste/m² in construction phase
- 78.46 kWh/m² energy consumption
- Ground source heat via heat pump – SCOP 4.65
- Leakage rate of 0.22
- Energy class A (passive house standard)
Consto and Siva have proven that it is possible to achieve world-leading results – even in demanding environments.
“Sustainability is an interdisciplinary effort. It’s about good communication and accountability.”
– Ida Bordi Stene, project manager and BREEAM manager at Consto
