Records marked Prototype are illustrative examples demonstrating the platform data model — not verified Jarlhalla research, and not citable as findings. The absence of that marker is not itself evidence: treat any record as unverified until it shows its sources and a verification date, and note that a workflow status is never proof that a claim is true. Read the provenance note.
Jarlhalla Research Hub
We collect, structure and publish ongoing research, observations, signals and evidence — continuously, in the open, with every claim traceable to its source and its level of verification stated.

Source-grounded research proposal, not a verified finding. The buildingSMART property-set concept describes how named properties, values and units are associated with objects or object types. This development documentation is schema background, not evidence of round-trip losses.…
Source-grounded research proposal, not a verified finding. JRC describes the second-generation Eurocodes programme and its transition framework. Programme-level material is not a completed Eurocode 5 literature review or proof of Norwegian design consequences. Previous counts of…
Source-grounded research proposal, not a verified finding. The EEA briefing examines circular renovation approaches and their implications for material use and embedded greenhouse-gas emissions. EU renovation evidence provides context, not validation of stalled, brokered or…
Source-grounded research proposal, not a verified finding. The PESETA IV report assesses climate-change impacts on windstorms in the EU. Climate-impact research does not prescribe Norwegian design loads, authorize departure from a national annex or establish liability…
Source-grounded research proposal, not a verified finding. The NIST AI RMF Playbook Measure function addresses appropriate metrics and assessment of AI system performance and fitness for purpose. This supports general evaluation design, not Norwegian building compliance or…
Source-grounded research proposal, not a verified finding. WoodWorks guidance identifies deep wetting, trapped moisture and repeated wetting and drying as construction moisture risks, and recommends planning moisture-control strategies. Practitioner guidance does not establish…
