The potential of Earth-to-Air Heat Exchangers for reducing energy demand in Spanish dwellings
Bibliographic record
Abstract
An earth-air heat exchanger (EAHX), also known as Provençal well or Canadian well, is a system for cooling and heating buildings using the ground as a heat sink/source. This study is dealing with earth-air heat exchanger (EAHX) implementation for Spanish dwellings. The objective is to assess the potential of this solution for HVAC energy savings and greenhouse gas emissions reductions. A numerical study is conducted to assess the thermal behavior of EAHX using the transient simulation tool TRNSYS. The simulations are carried out for typical Spanish single family detached home, taken into account three different climate regions. Detailed results are presented concerning EAHX thermal behavior and its benefits in terms of energy savings and anti pollution effects for fresh air pre-heating and pre-cooling within mechanical ventilation system of the house.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
