A system is an entity with recognizable parts or subsystems that in some way overlap or interact in time and space. This overlap of functions and degree of interactions project a singular purpose or identity of the system. A system is conceptual totality, but need not be a fathomable entity, like the atmosphere system. Systems have parts or subsystems that may seem to participate with other system. Such transcending parts individually reflect the nature of the systems they subsist on.
Systems are also finite when they exist within an environment of discipline. Such open systems also have nodes where other distinct systems get attached. Many such interconnected systems again serve a singular purpose. Compared with the interconnected or open systems, there could be self-sustaining systems. Such systems are strongly contained, and so are closed systems. Open systems interact with other systems or outside environment, and Closed systems have little interaction with other systems or outside environment. Our body is an open system as it continuously interacts with the environment, where as a watch is nearly self sufficient entity.
Open system have external interactions, such as of information, energy, material and other resources export-import. Open systems retain the enthalpy to be in equilibrium. Open systems are like a digital word processor article or a spreadsheet which are amenable to changes or can be “adjusted’. Some legal agreements could an ironclad or closed document, which once created cannot be changed in any part, and must be redrawn. A quasi-legal agreement could be an understanding, an open document allowing future change or revision.
In Architecture, buildings are classifiable into Open-ended and Closed-ended entities. An open-ended form and structure allow extensions or additions. Open-ended structures allow spatially limited or occasional alteration. Open-ended buildings have identifiable subsystems, each of which can be designed, executed, maintained, operated, upgraded, replaced or terminated by different agencies, at different times and circumstances. Open-ended systems inherently have multiple units of modulated sizes, form consistency patterned arrangement and perceptible organization.
Closed-ended structures have a self-sufficient form and singular purpose. Such structures reflect the one master ownership or single intent, and so are monumental, akin to a piece of sculpture. There may be nonfunctional repeat units in the composition for pattern making. A closed system does not transect anything, and may not have nodes of exchange. One need not be aware of the interior of the system, as there are ‘no repairable or serviceable components inside’. Such tags are very common on technical products of proprietary design.
Certain forms or shapes are dominantly, either Closed-ended or Open-ended. Forms that are broader at the base, and narrower or pointed at the top, do not allow extension. Pyramid, cone or tower, are closed ended systems. Similarly drum like shapes allow little additions except in the upward direction. Contrary to this, a square or rectangle is very extendible shape in all directions. Old Basilicas and Church buildings have been added upon, but Hindu temple is rather a static form.
Highly articulated buildings like Versailles or British Parliament, are closed ended or static structures. It would be difficult to add upon them in any relevant manner without compromising the integrity of the built-form. Indian Parliament has an annex connected with an access tunnel. Versailles has glass pyramids (closed ended entities) as new extension.
Architects create monumental buildings by compromising many other functions or requirements. For such purposes the building is conceived with a single form (though transgressed in many ways), single material, or sensuality, nonhuman or disproportionate scale and fewer sub elements. Some explorations towards closed ended architecture or monumental buildings have been deconstructionist, gravity defying and highly dynamic or mobile forms.
