Abstract

fetched live from OpenAlex

This paper presents development of a model for analysis of energy and exergy utilisation within an urban centre of Calgary, Canada. The analysis began with the detailed assessment of energy resource utilisation patterns and energy flows across six different energy consuming sectors, namely energy generation, residential, commercial, industrial, transportation and agricultural. For each sector, the energy and exergy efficiencies were determined. Calgary's overall energy and exergy efficiencies were found to be 40.9% and 15.7%, respectively. Thereafter, the developed model was used to identify energy and exergy losses in different sectors and potential areas for improvement. It was determined that, by switching coal with natural gas by 50%, the CO2 emissions can be reduced by 24.3%. In addition, as much as 31.5% reduction in emissions is also possible by reducing the electricity usage up to 50%.

Not 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.
