Canadian Construction Materials Centre guidelines for the evaluation of vacuum insulated panels
Bibliographic record
Abstract
Within the construction product sector, the evaluation of innovative products is not a new activity. Over the last 30 years, the Canadian Construction Materials Centre (CCMC) has conducted evaluations on various innovative construction products in accordance with CCMC Technical Guides. Over the last decade, increasing attention has been paid to improving the energy efficiency of buildings. Hence, there is currently a growing interest in manufacturing products using complex composite materials, innovative raw materials and nanotechnology to meet new energy regulations and user expectations. The use of vacuum insulated panels (VIPs) as an alternative to standardized thermal insulation products offers a far greater thermal insulating capacity, but also raises some challenges, particularly with respect to the installation of VIPs. This paper is an overview of the CCMC protocol to assess VIPs for compliance with the National Building Code of Canada (NBC), which considers two designated exterior wall applications: curtain walls and non-loadbearing steel stud walls.

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.
