Abstract
This chapter discusses some of the concepts and ideas that have been proposed that help facilitate building material and component reuse and that break down some of the barriers. Concepts such as salvageability, secondary use, material flow analysis and urban mining all help to establish a theoretical base for processes that enable buildings to be created using components and materials that have had a previous use. Urban metabolism principles have been employed to analyse the interrelations between environmental, sociological and economic factors of cities to understand the flow of resources through a city, as well as the relationships between urban areas and their hinterlands. The deconstruction (DfD) concept affects the design of all material levels that are accounted for by the technical composition of buildings. In 2005 McDonough and Braungart Design Chemistry (MBDC) launched Cradle to Cradle (C2C), a conceptual framework for assessing and certifying the impact of products, including building components.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
