core I: extensive/intensive

Cristina Parreño

This project uses a transformation system based in Grasshopper to create an architecture that uses intensive processes of convection and conduction thermodynamics in a first state, and the process of radiation in the second to inform the extensive properties. Through a thick envelope, compact structure and central temperature/people circulation system, the first state utilizes the attributes of the stack effect and a central chimney to drive and enhance its thermodynamic system. As the armature unfolds the geometry (in Grasshopper) into a second, exposed state, the radiation and shading enables a completely different thermodynamic and organizational environment. The proposal references, enables, and explores the dichotomy between environments, geometries, thermodynamic systems, and circulation systems.
