Efficiency, in the world of construction, hinges on two factors: weight-to-volume ratio and scalability. The Pneuma rejects traditional methods of building with rigid and massive materials, opting instead to use air. Although air is frequently explored as a building medium, there has yet to be a standardized mode of construction with it. In response, The Pneuma uses a finite set of mass-produced materials and typical assembly details to create an infinite set of formal expressions. Using recycled exercise balls, Cradle to Cradle Fabric (Mermet GreenScreen Evolve 10%), and rented scaffolding (Colgate Scaffolding NYC), the pavilion is a collection of amorphous geometries that morph from canopies to seating elements. The taut fabric registers nuanced air pressure changes in the inflated balls, generating an unlimited array of forms with a limited set of modules.
