Effect of Sky View Factor on Outdoor Temperature and Comfort in Montreal
Bibliographic record
Abstract
Abstract The relationship between the sky view factor (SVF) and the urban heat island (UHI) effect in Montreal is explored, by assessing the effect of SVF on air temperature ( T a ) and mean radiant temperature (MRT). The amount of energy consumed by indoor heating and air conditioning is affected by T a . The value of MRT is the sum of all short-wave and long-wave radiation fluxes absorbed by the human body that affects its energy balance and human thermal comfort. SVF in urban areas affects both T a and MRT. We used a microscale urban climate model (ENVI-met) and simulated the effect of building geometry in four typical urban districts (each 300×300 m 2 in size) in Montreal, on air and human weighted mean radiant temperature (MRT human weighted ) at 1.5-m height above the ground. Urban development consideration of a low SVF could mitigate the UHI effect, by decreasing urban temperatures and increasing outdoor thermal comfort. Most UHI studies are carried out for cities in hot and dry climates; however, UHI mitigation can also reduce energy consumption in colder cities, such as Montreal. Results of this analysis can be used in environmental urban planning standards.

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.
