Abstract

fetched live from OpenAlex

This study presents an exploratory, in-depth case study on the short-term thermal and hygrothermal performance of a cement-stabilized, core-insulated rammed earth house in a cold-climate region of eastern Canada. Rammed earth construction is increasingly promoted as an eco-efficient solution for winter-dominated climates due to its thermal and moisture-regulating properties, however, empirical validation under real-world conditions remains limited. A three-day monitoring campaign was conducted under free-running winter conditions using three complementary methods: infrared thermography (IRT), surface heat flux sensing, and in-situ temperature and humidity measurements. The results reveal measurable thermal lag, reduced diurnal temperature swings, and delayed heat dissipation during unheated periods, indicating high passive heat retention. IRT demonstrated dynamic surface temperature responses to solar exposure, particularly on the south-facing wall, while heat flux data confirmed reduced transmittance through the composite earthen envelope. Indoor temperature and relative humidity remained stable throughout the monitoring period, reflecting effective hygrothermal buffering. Although limited in duration and scope, this study provides a rare, high-resolution benchmark dataset that characterizes the short-term behavior of insulated rammed earth walls in cold climates and supports future simulation-based and long-term field investigations.

Not 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.
