This project restores the Arctic tundra ecosystem by transforming two invisible spectrums—ultraviolet (UV) and infrared (IR)—into architectural operations. UV is expressed through floral color and UV patterns that guide pollinators, while IR is revealed through bird nesting behavior and branch deformation that indicate soil instability caused by warming. A network of Outposts measures how roof angles, materials, and shadows modify these indicators, documenting changes in floral UV visibility, ground temperature, and nest stability. This data informs the Archive, which operates as an Inverse Preserve: rather than enclosing protected nature, it actively produces restorative microclimates. Tall roof structures cast cooling shadows, reestablish UV cues, and stabilize permafrost soils, forming a resilient ecological core as the surrounding landscape deteriorates. Located in Churchill, Canada, the Archive propagates restored seeds through visitors, extending ecological repair beyond the building and proposing a new climatic model for architectural restoration.
