What do outer space capsules, submarines, and office buildings have in common? Each was conceived as a closed system: a self-sustaining physical environment demarcated from its surroundings by a boundary that does not allow for the transfer of matter or energy.
The history of twentieth century architecture, design, and engineering has been strongly linked to the conceptualization and production of closed systems. As partial interpretations of the world in time and in space, closed systems identify and secure materials necessary for life. Contemporary discussions about global warming, recycling, and sustainability have emerged as direct conceptual constructs related to the study and analysis of closed systems.
