Abstract

fetched live from OpenAlex

Statistical regression models were developed to permit the rapid modelling of large commercial office buildings within a single climate zone.The regression models are developed using a large number of building parameters and their hourly energy model simulated results.In previous building energy regression modelling, there is a research gap in selecting building parameters using statistical approaches.This paper investigates a feature selection method, including forward stepwise selection and LASSO regression, to identify building parameters that, together, have the most significant impact on total building energy load.The regression model, with 25 features selected through this methodology, predicts total energy load at 93.5% accuracy, on average.

Full frame distilled prediction

Teacher imitation

Not 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.
