Abstract
Over the past 10 years in Europe and North America, passive house standards have become the leading high-performance building standards. Although site energy metrics are paramount in these standards, the roots are in reducing carbon emissions. This article describes the influence that using regional, rather than broad (i.e., continent-wide), energy supply carbon emission factors can have on the life cycle operating carbon emission outcome for single-family dwellings designed according to a passive house standard for three climatic locations across Canada, using two mechanical systems with different fuels. All three cities significantly differ when using regional carbon emissions factors, compared with a broad average. Recommendations are made to generate a hybrid carbon intensity factor balancing national and regional electrical grid carbon intensities. As the passive house standards become more and more mainstream paths to reducing the carbon impact of buildings, understanding the differences between emissions factors becomes increasingly important.

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
