Code national du bâtiment : Canada : 2020
Bibliographic record
Abstract
The National Building Code of Canada (NBC) 2020, developed by the Canadian Commission on Building and Fire Codes and published by the National Research Council of Canada, sets out technical requirements for the design and construction of new buildings, as well as the alteration, change of use and demolition of existing buildings. Over 280 technical changes have been incorporated in this new edition, improving the level of safety, health, accessibility, fire and structural protection, and energy efficiency provided by the Code, and expanding the NBC into new areas. Significant changes in the NBC 2020 • Technical requirements for large farm buildings are added, which address fire protection, occupant safety, structural design, and heating, ventilating and air-conditioning. • Encapsulated mass timber construction is introduced, enabling the construction of wood buildings with up to 12 storeys. • Accessibility requirements are updated to reduce barriers related to anthropometrics, plumbing facilities, signage, entrances and elevators. • Design requirements for evaporative equipment are revised to minimize the growth and transmission of Legionella and other bacteria. • A home-type care occupancy is introduced to allow safe and affordable care in a home-type setting. • Energy performance tiers are established to provide a framework for achieving higher levels of energy efficiency in housing and small buildings.

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.
