The Potential for Perennial Vines to Mitigate Summer Warming of an Urban Microclimate
Bibliographic record
Abstract
Shading and evapotranspirative cooling by vegetation are important controls on moderating rise in city temperatures and mitigating urban heat islands. The purpose of this research is to evaluate the potential of Boston ivy (Parthenocissus tricuspidata) to mitigate warming of building surface temperature in an urban core. Temperature loggers were placed on vine-shaded and non-shaded walls in Toronto, Canada to collect surface temperatures over a six-month period. During peak solar access periods, average vine-shaded and non-shaded temperature differentials of up to 6.5 °C and 7.0 °C for the south and west-facing walls were measured, respectively. Predictive models were developed to estimate daily degree hour difference (DHD), a metric for capturing the temperature moderating potential of vines. At ambient air temperatures exceeding 22 °C, ambient air temperature and solar radiation were significant positive drivers of DHD. Results are important to further understanding urban plant-microclimate interactions and strategies for heat island management.

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.
