DGH No-AC Cooling Power Score
The DGH No-AC Cooling Power Score is a 0-10 composite (higher = more cooling relief per layer); ranks each layer of a no-AC dorm cooling system by how much felt heat it removes in a 100-square-foot room where a window or portable AC is banned composite score. weighted composite (0-10): cooling_impact 35% + coverage_reach 25% + heat_source_mitigation 20% + dorm_legality_footprint 20%. cooling_impact credits a real temperature drop (evaporative coolers) or enough sustained airflow to move felt heat (air circulators) over a fan that only stirs nearby air; coverage_reach rewards whole-room circulation that holds at distance over point or personal cooling that fades a few feet out; heat_source_mitigation credits stopping heat at its source (blocking solar gain at the window, cooling the body at the mattress) rather than only treating the symptom; dorm_legality_footprint scores how cleanly the product clears a typical window/portable-AC ban and tucks into a shared room.

Formula
weighted composite (0-10): cooling_impact 35% + coverage_reach 25% + heat_source_mitigation 20% + dorm_legality_footprint 20%. cooling_impact credits a real temperature drop (evaporative coolers) or enough sustained airflow to move felt heat (air circulators) over a fan that only stirs nearby air; coverage_reach rewards whole-room circulation that holds at distance over point or personal cooling that fades a few feet out; heat_source_mitigation credits stopping heat at its source (blocking solar gain at the window, cooling the body at the mattress) rather than only treating the symptom; dorm_legality_footprint scores how cleanly the product clears a typical window/portable-AC ban and tucks into a shared room.
