Impact of added insulation on the hygrothermal performance of leaky exterior wall assemblies
Bibliographic record
Abstract
This project proposes an experimental procedure to evaluate the effect of adding insulation to leak exterior wall assemblies and to monitor air leakage paths within them. The procedure involves the construction of a full-scale test hut exposed consecutively to climatic conditions representing winter and late spring, inside the environmental chamber. Two re-insulation strategies are studied, with three different air leakage patterns, and compared to an insulated base-case. The construction of the hut is typical of low-rise wood frame residences in Quebec, insulated with glass fiber batt insulation between the studs. The objectives of the experimental work are: (1) To study the effect of different insulating strategies for exterior wall assemblies having different air leakage characteristics on the moisture content and temperature distribution patterns in walls when exposed consecutively to wetting and drying conditions; (2) To develop and implement a method of characterizing air leakage paths so that more is known about the movement of air through exterior wall assemblies; (3) To produce patterns that could be used to validate existing models.

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.
