EVALUATION OF AN APPROXIMATE METHOD FOR PREDICTING THE U-VALUE OF A WINDOW WITH A BETWEEN-PANES LOUVERED SHADE
Bibliographic record
Abstract
A numerical model has been developed of the conjugate convection, conduction and radiation heat transfer in a double glazed window with a between-panes venetian-type blind. The two-dimensional finite-volume model has been validated for a range of slat angles using U-Value measurements from the open literature. This "Full CFD Model" has been used to show that the thermal performance of the window/blind enclosure can be closely approximated using a much simpler model. The "Simplified Model" combines data from a convection-only CFD solution with a six-surface radiation model. For both standard (high-e) and low-e windows, it has been shown that the Simplified Model can predicted the U-Value of the window/blind enclosure to within 1.5 percent, compared to the Full CFD Model. It has also been shown that the Simplified Model can account for geometric effects, such as the blind being located off the centre line of the gas-filled enclosure. Air was the fill gas in all calculations.

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.
