User's Guide: National Energy Code of Canada for Buildings 2020
Bibliographic record
Abstract
The User's Guide – National Energy Code of Canada for Buildings 2020 is designed to complement the National Energy Code of Canada for Buildings (NECB) 2020 by providing background information as well as detailed examples and calculations. This edition of the User's Guide has been updated to • introduce energy performance tiers, which provide a flexible compliance framework for achieving higher levels of energy efficiency in buildings, • include additional examples of determining the thermal characteristics of building envelope assemblies, • provide guidance on whole building airtightness testing, • describe the six different compliant HVAC systems, and • explain compliance using whole-building energy modeling. The User's Guide serves as a reference tool for those involved in building design, construction, or regulation. It explains the NECB's provisions and includes examples to assist users in understanding energy-efficient design. The guide can also be used as a resource for educators and trainers when instructing students and professionals.
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.
