Durability Characterization of a High Performance Building Envelope with Vacuum Insulation Panels and Energy Recovery Ventilation
Bibliographic record
Abstract
Vacuum insulation panels (VIPs) can help achieve thin, highly insulated building envelopes, but poor implementation and insufficient ventilation can lead to durability issues.This thesis describes a field study that was used to characterize the durability of a research house with a thin, VIP-integrated building envelope and an energy recovery ventilator (ERV).The study employed long term hygrothermal monitoring of the building envelope and various tests to evaluate the insulation performance, airtightness, and ventilation effectiveness.The impacts of VIPs and ventilation on durability were discussed, with emphasis on moisture buffering, drying potential, mold growth risk, and VIP aging.The house demonstrated exceptional insulation performance with no risk of visible mold growth during the study.The walls and floor showed acceptable conditions for VIP longevity, and the ERV showed a potential to sufficiently buffer indoor moisture loads.Recommendations were provided to improve the durability and efficiency of the house.

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.
