ABSTRACT
The traditional idea of architecture was transformed strongly by pervasive appliances and technical systems in the twentieth century. Beyond serving modern notions of comfort or hygiene, building equipment became an imperative of construction and a central structuring element. Addressing the knowledge-driven implications of man-made underground environments, the paper is aimed at broadening the understanding of the role of building services in the transformation of architectural production. Located around the historic centre of Zurich, the infrastructural facilities Central (1942–43), Hohe Promenade (1964–68), and Urania (1970–74) concurrently serve as parking garages and public shelters. Yet the actual challenge of these designs by architect Gottfried Schindler was the provision and conditioning of air.
