Abstract

fetched live from OpenAlex

Abstract This study aimed to prevent chemical air pollution and reduce its influence on occupants' health in a university building under renovation. Since starting the renovation work, the occupants' health status was monitored using questionnaires every summer and winter. According to a first questionnaire collected before the renovation, subjective symptoms were not observed. However, some occupants complained about odor after moving into their new rooms. Therefore, all interior materials used for the construction work were examined in small chambers to obtain their chemical emission characteristics. The assembled floor, which was a polyvinyl chloride floor sheet combined with a concrete slab by adhesive, was predicted to be the main source of odor in the renovated rooms. Two strategies were implemented individually in rooms to remove these odorous chemicals; a chemical filter in indoor air conditioning units and forced ventilation with hot‐humid outdoor air. The performance of each technique was validated by measuring the indoor concentration before and after operation. These results showed that both strategies had a significant effect on reducing volatile organic compounds (VOCs), in a practical way.

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.
