Envelope air pressure design load: an approach for hygrothermal analysis of retrofitted high-rise masonry wall assemblies
Bibliographic record
Abstract
This paper presents the analytical approach to predict envelope air-pressure differential that was newly implemented into IRC’s computer weather analysis tool for hygrothermal calculations WeatherSmart-1.1 . In addition to its original features, this tool now allows obtaining in a user-friendly way yearly profiles of hourly envelope air-pressure differential for both low and high-rise buildings. Hourly envelope air-pressure profiles are derived from the knowledge of both indoor and outdoor hygrothermal design loads. WeatherSmart-1.1 is being used within the frame work of a research project to assess effects of adding supplementary insulation and air-sealing retrofit on the long-term hygrothermal performance of different wall types used in Canadian high-rise buildings. Within the frame work of this research project, the paper also introduces how effects of moist air infiltration and exfiltration across tall building envelopes are assessed using IRC’s advanced HAM model hygIRC .

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.
