Abstract

fetched live from OpenAlex

Abstract Designing for climate resilience and carbon neutrality implies low-emission structures that double as thermal mass. In this study, the effect of using geometry to maximize natural surface convection on an internal thermal mass is investigated. Wood and concrete thermal masses are optimized for both instantaneous heat transfer and transient heat storage, and compared. It is found that the addition of optimally-sized fins can double or triple the convection coefficient at the interior surface, provided the thermal conductivity of the fins is sufficiently high. Doubling or tripling the surface heat transfer translates to an equivalent increase in dynamic energy storage, so long as the mass thickness, wall area, and vent openings are recalibrated to maintain thermal synchrony at the building-level.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
