Ventilverlusten
Ventilverlusten is a term used in speculative urban science to describe a hypothetical failure mode of large-scale building ventilation networks, in which interactions among ducts, fans, sensors, and control systems produce emergent air-flow patterns and local climatic anomalies within a city or large facility. The word combines ventil- from ventilation with loss (-verlust) to indicate a systemic loss of intended airflow control. It is not a standard engineering diagnosis, but a conceptual framework used in fiction and theoretical discussions to examine how automated ventilation might behave under stress.
In the fictional and analytical usage, Ventilverlusten refers to the buildup of pressure differentials when parts
In literature and media, Ventilverlusten has been employed as a metaphor for dependency on centralized climate
