LCA Validation & Circularity

PROJECT CONTEXT
Validation of the peer-reviewed whole-building LCA of the built NEST UMAR circular-housing unit, reconstructing its material-passport and circularity logic and mapping the published performance to a 2026 Swiss KBOB/SIA reassessment workflow, while documenting the public-data limits that prevent a defensible absolute carbon recalculation.
