Abstract
It is often claimed that the cheapest energy is the one you do not need to produce. Nevertheless, this claim is somewhat unsubstantiated. In this article, we try to shed some light on this issue by using the energy return on investment (EROI) as a yardstick. This choice brings semantic issues because the EROI is used in a different context than that of energy production. Indeed, while watt and negawatt share the same physical unit, they are not the same object, which brings some ambiguities in the interpretation of EROI. These are cleared by a refined definition of EROI and an adapted nomenclature. This review studied the research in the energy efficiency of building operation, which is one of the most investigated topics in energy efficiency. Impact of insulation, high efficiency windows, and other energy efficiency measures were considered. These results were normalized for climate, life time of the building, and construction material. In many cases, energy efficiency measures imply a very high EROI. Nevertheless, in some circumstances, this is not the case and it might be more profitable to produce the required energy than trying to save it.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
