1 AIRFLOW AND HEAT TRANSFER MEASUREMENTS NEAR A FAÇADE WITH DIFFERENT HEATING CONFIGURATIONS
Bibliographic record
Abstract
This paper presents the experimental results of temperature and air velocity field measurements near a glazed façade located in a test chamber at the Hydro-Quebec (LTE) research laboratory in Shawinigan, Quebec. The façade separates a cold room from a warm room (at normal conditions), both controlled. The objective of the experiment was to examine the air movement and heat transfer near the windows with and without shading and with different perimeter heating configurations (for winter conditions). The chamber is equipped with three types of heating systems: electrically heated windows, a baseboard heater and a radiant ceiling panel. 2-D velocity field measurements were performed on a 15cm×11cm vertical plane perpendicular to the window surface using a Particle Image Velocimetry (PIV) system. A 2-D motorized traverse system was used to allow measurements at different heights, closer or further away from the façade. The thermal stratification in the room was monitored using a grid of thermocouples at different heights and distances from the facade. The general objective of this work is to develop design recommendations for high performance facades that will reduce or eliminate perimeter heating in buildings as a secondary heating system.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
