PERFORMANCE OF HEAT PUMP CHILLED FOUNDATIONS
Bibliographic record
Abstract
Standard domestic ground coupled heat pump technology has been applied to maintain frozen ground in and beneath insulated slab-on-grade foundations while simultaneously providing substantial heat for the building itself. Thermal and economic performance data are presented for the first year of operation of two-350 m2 multi-purpose municipal garage buildings located on permafrost in the W o n. The two cases bracket the range of soil conditions, ground temperatures, operating conditions and logistic problems likely to be encountered in practice. The thermal regime within the foundations was simulated by a numerical model.and the results were used to suggest ways of improving the design. The ground coupled heat pump chilled foundation has the advantage, relative to the alternatives, of beiig less affected by external air temperatures. Initial construction is cheap while net operating costs for electic heat pumps range from negligible to reasonably acceptable. Diesel or natural gas driven heat pumps would further reduce operating costs. The paper also suggests additional possible applications of groundcoupled heat pumps to permafrost engineering.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
