Abstract
In an effort to reduce fossil fuel consumption and greenhouse gas emissions in the Canadian residential sector for space heating, a first-of-its-kind seasonal solar high-temperature borehole thermal energy storage (BTES) with district heating system for a community of 52 houses was built and has been in operation in Okotos, Alberta, Canada since 2007. In the last five years, the system was able to achieve an average solar fraction and coefficient of performance of 96% and 27, respectively. This study aims to improve the thermal efficiency of the system by implementing a simple organic Rankine cycle (ORC) to generate electricity for operating pumps in the system, and utilizing the solar energy stored in the BTES at 60–80°C as the heat source. The study shows that it is thermodynamically feasible.

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
