A Method for the Assessment of Moisture Conditions of Painted Wood Siding in Historic Wood Frame Buildings
Bibliographic record
Abstract
There are many wood frame buildings in the Ottawa area with painted wood siding.As vinyl is a popular replacement, most historic buildings continue to use wood due to its heritage value.Painting the wood siding protects the underlying material from degradation from the surrounding exterior environment.For painted wood siding, periods of high moisture content can lead to premature decay of the wood or cause paint to blister.The role of the paint layer and its importance in protecting wood siding from moisture is the focus in this research.The permeability of the paint layer to vapour and liquid moisture sources is analyzed using WUFI Pro based on the Sd-value and Aw coefficient.Interior and exterior sources of moisture were found to impact the exterior siding.For Ottawa's climate, an exterior paint layer that is permeable (Sd<=0.5m)and with a lower Aw coefficient (<=0.0003kg/m 2 h 0.5 ) is recommended.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
