Monitoring and modelling of a prefabricated exterior envelope retrofit
Bibliographic record
Abstract
As part of a larger project to develop prefabricated technologies for retrofitting building envelopes of Canadian homes, a small building was retrofitted and instrumented. This prefabricated retrofit method is intended to be applied directly over existing cladding. Two prototype retrofit wall systems were installed on the building; a nailbase panel, and a wood frame panel. The existing wall had an RSI value of 1.80 m2K/W (including film coefficients) and the resulting retrofitted walls reached values of 6.40 m2K/W and 5.72 m2K/W. With the addition of a new air barrier, blower door tests have shown a large reduction in infiltration from 7.62 ACH to 0.82 ACH at 50 Pa. This paper discusses the approach taken, the construction of the prefabricated panels, preliminary in-situ RSI measurements, and modelling of thermal bridging and energy savings for the pilot project.

How this classification was reachedexpand
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.
