Illustrated User's Guide: NBC 2020: Part 9 of Division B, Housing and Small Buildings
Bibliographic record
Abstract
The Illustrated User’s Guide for the National Building Code of Canada 2020: Part 9 of Division B, Housing and Small Buildings features hundreds of graphics, examples and calculations. This edition of the guide provides updated information on the following topics: • Safety measures for openable windows in buildings of residential occupancy • Home-type care occupancy and related fire protection measures • Penetrations of fire separations by outlet boxes, service equipment, raceways, sprinklers and fire dampers • Vapour barrier materials and their uses • Connectors and fasteners in contact with preservative-treated wood and the penetration of fasteners for cladding, shakes and shingles • The location of exhaust outlets • Airtightness testing of the building envelope and requirements for the use of test results to determine airtightness levels • Energy performance tiers, which provide a flexible compliance framework for achieving higher levels of energy efficiency in housing and small buildings • A prescriptive trade-off path with energy conservation measures that can be credited with energy conservation points to attain Energy Performance Tier 2 The User’s Guide helps builders and designers understand the National Building Code of Canada 2020 as it applies to housing and smalls buildings. It also provides detailed explanations of the principles and rationale behind the provisions of Part 9.

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.
