title Foundations for a Constraint-Based Floor Plan Layout Support in Participatory Planning of Low-Income Housing
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 283-287
summary We introduce the foundations of a novel approach that deals with constraint-based design methods to supporting participatory planning processes of low-income dwellings. We examine the space allocation problem inside the architectural domain on the basis of graph theory and combinatorics, providing a concise mathematical background for an implementation strategy called FLS (Floor plan Layout Support), which is analyzed here for the first time regarding this particular context of application. The philosophy underlying a design method that is mainly driven by the formulation of distinct constraints suggests to avoid the traditional procedure of first to create a yet not necessarily valid instance of the eventual design solution by directly choosing specific parameter values of its shape, and later on to evaluate its validity by confronting the designed model to a set of applicable constraints. Instead, constraint-based design poses a search procedure that operates in a space of planning-relevant constraint sets. The FLS methodology integrates some few principles of constraint-based automated reasoning with high user interactivity, into a design environment where as much dwellers as planners can collaboratively work in solving spatial organization problems of housing projects. The FLS model of application makes use of a combination of dweller-specified constraints, planning and zoning regulations, and a small library of modular space units. Constraint-based design ! methods are particularly capable of supplying efficient support for the collaborative involvement of dwellers into the architectural programming process of her/his own home. Mainly, because dwellers themselves tend to describe their space need and design intentions as a set of constraints on room quantity, space utilization, circulation system, allocation of available furniture, available budget, construction time, and so forth. The goal is to achieve an integrated tool for finding and modelling topologically valid solutions for floor plan layout alternatives, by combining user-driven interactive procedures with automatic search and generative processes. Thus, several design alternatives can be explored in less time and with less effort than using mainstream procedures of architectural practice. A FLS implementation will constitute one system module of a larger integrated system model called Esther. A FLS tool shall interact with other functional modules, like e.g. the BDS (Building Bulk Design Support), which also uses constraint-based design methods. A preliminary procedural model for the FLS was tested on Chile’s official social housing standards (Chilean Building Code – OGUC. Art. 6.4.1) which are very similar to most Latin American housing programs currently in operation.

title Controlled Unpredictability: Constraining Stochastic Search as a Form-Finding Method for Architectural Design
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 263-267
summary Provided with a strict set of rules a computer program can perform the role of a simple designer. Taking advantage of a computer’s processing power, it can also provide an unlimited number of variations in the form while following a given set of constraints. This paper delineates a model for interrelating a rule-based system based on purely architectural considerations with non-deterministic computational procedures in order to provide controlled variations and constrained unpredictability. The experimental model consists of a verisimilar architectural problem, the design of a residential tower with a strict program of 200 units of different types in a given site. Following the interpretation of the program, a set of rules is defined by considering architectural concerns such as lighting, dimensions, circulations, etc. These rules are then encoded in a program that generates form in an unsupervised manner by means of a stochastic search algorithm. Once the program generates a design it’s evaluated, and the parameters on the constraints are adjusted in order to produce a new design. This paper presents a description of the architectural problem and of the rule building process, images and descriptions of three different towers produced, and the code for the stochastic-search algorithm used for generating the form. The succesful evolution of the experiments show how in a computation-oriented design process the interpretation of the problem and the rule setting process play a major role in the production of meaningful form, outlining the shifting role of human designers from form-makers to rule-builders in a computation-oriented design endeavour.

title A Multi-Agent Model for Generating Local Land-Use Plans in the Context of an Urban Planning Support System
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 153-168
summary In a multi-player urban planning process, the outcome of any individual decision of the actors is uncertain until a state where the plan is satisfactory for all. To support the plan generation phase, this paper develops a generic multi-agent system, in which agents represent particular land-uses. In the system, agents higher in the hierarchy have priority over agents lower in the hierarchy to claim units of land. This one-direction claim process may result in a plan that is not optimal for every agent. The system, therefore, allows agents to revise their plans in an iterative procedure. A case study illustrates centralized, semi-centralized and decentralized solutions for a plan area based on the outcomes of different strategies used by facility agents (retail, green, schools) and a housing agent. The results show that the proposed system is able to generate rational and realistic plan alternatives for new residential areas.

summary This paper presents a computational system for enriching design discovery in the external 2D representation of architectural plans. Enriching discovery is achieved through an interpretative search process that involves emergent findings. The developed computational system employs a twofold discovery process, generative phase and an interpretative or explorative phase. In the generation phase the system allows designers to depict an initial building design in the form of 2D plans as a set of lines. The system recognizes possible components of the initial design by generating different forms of bounded shapes that are both explicit and implicit using the Hamiltonian circuit approach. In the interpretation phase the discovery process using the quest mechanism is invoked by selecting a geometrical semantic identified in the recognized shapes to generate possible alternative interpretations of the complete representation of initial design. This plays an important role in enriching discovery in the architectural design of buildings and provides a set of new moves and directions for the designer to pursue.

title A Heuristic Method for Land-Use Plan Generation in Planning Support Systems

summary Existing land-use allocation methods assume that the suitability of a spatial distribution of land-uses can be measured as the sum of suitability scores across parcels. Although this may be plausible for some land-uses, facilities such as retailing, schools, medical services, etc., intend to serve the needs of a local population and should be evaluated at the level of a facility network, instead. The purpose of the present paper is to develop a method that combines a suitable heuristic for facility-location planning with an existing mechanism for land-use allocation, to solve this shortcoming of existing models. In specific, the proposed method combines the interchange heuristic for locating facilities and a swapping heuristic for area-type land-use allocation in a multi-agent framework. A case study shows that the method generates plausible land-use plans in reasonable computation time.

title I3-Eye-Cube: interactive intuitive mixed reality interface for virtual architecture
source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary This paper introduces a new tangible interface for navigating through immersive virtual Architecture. It replaces the common mouse or glove with a set of tangible cubes. It includes physical architectural floor plans as contextual haptic constraints for the cubes to ensure better object manipulation compared to free space. The position and orientation of the cubes relative to the floor plan is tracked by web cameras and a newly developed program translates this into the 6-dof of the virtual camera generating a 3D view for the immersive projection of virtual architecture. This easy to use tangible interface mixes common 2D dimensional (real) with 3D immersive representation (virtual) of Architecture to overcome the problem of ‘Getting lost in Cyberspace’.

title Teaching parametric design in code and construction
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 158-161
summary Automated manufacturing processes with the ability to translate digital models into physical form promise both an increase in the complexity of what can be built, and through rapid prototyping, a possibility to experiment easily with tangible examples of the evolving design. The increasing literacy of designers in computer languages, on the other hand, offers a new range of techniques through which the models themselves might be generated. This paper reviews the results of an integrated parametric modelling and digital manufacturing workshop combining participants with a background in computer programming with those with a background in fabrication. Its aim was both to encourage collaboration in a domain that overlaps both backgrounds, as well as to explore the ways in which the two working methods naturally extend the boundaries of traditional parametric design. The types of projects chosen by the students, the working methods adopted and progress made will be discussed in light of future educational possibilities, and of the future direction of parametric tools themselves. Where standard CAD constructs isolated geometric primitives, parametric models allow the user to set up a hierarchy of relationships, deferring such details as specific dimension and sometimes quantity to a later point. Usually these are captured by a geometric schema. Many such relationships in real design however, can not be defined in terms of geometry alone. Logical operations, environmental effects such as lighting and air flow, the behaviour of people and the dynamic behaviour of materials are all essential design parameters that require other methods of definition, including the algorithm. It has been our position that the skills of the programmer are necessary in the future of design. Bentley’s Generative Components software was used as the primary vehicle for the workshop design projects. Built within the familiar Microstation framework, it enables the construction of a parametric model at a range of different interfaces, from purely graphic through to entirely code based, thus allowing the manipulation of such non-geometric, algorithmic relationships as described above. Two-dimensional laser cutting was the primary fabrication method, allowing for rapid manufacturing, and in some cases iterative physical testing. The two technologies have led in the workshop to working methods that extend the geometric schema: the first, by forcing an explicit understanding of design as procedural, and the second by encouraging physical experimentation and optimisation. The resulting projects have tended to focus on responsiveness to conditions either coded or incorporated into experimental loop. Examples will be discussed. While programming languages and geometry are universal in intent, their constraints on the design process were still notable. The default data structures of computer languages (in particular the rectangular array) replace one schema limitation with another. The indexing of data in this way is conceptually hard-wired into much of our thinking both in CAD and in code. Thankfully this can be overcome with a bit of programming, but the number of projects which have required this suggests that more intuitive, or spatial methods of data access might be developed in the future.

summary This study describes a procedural design studio using Genetic Programming as the evolutionary mechanism and formal generation. This procedural design is integrated with a visualisation interface, which allows designers to interact and select from instances for design evolution. Evolutionary design facilitates designers in three areas: 1) diversify instances of design options; 2) inspect specific goals; 3) and enhance the possibility of discovering various potential solutions.

summary This paper presents a novel approach for the automatic creation of vegetation scenarios in real or virtual 3D cities in order to simplify the complex design process and time consuming modeling tasks in urban landscape planning. We introduce shape grammars as a practical tool for the rule-based generation of urban open spaces. The automatically generated designs can be used for pre-visualization, master planning, guided design variation and digital content creation in general (e.g. for the entertainment industry). In a first step, we extend the CGA shape grammar by Müller et al. (2006) with urban planning operations. In a second step, we employ the possibilities of shape grammars to encode design patterns (Alexander et al., 1977). Therefore, we propose several examples of design patterns allowing for an intuitive high-level placement of objects common in urban open spaces (e.g. plants). Furthermore, arbitrary interactions between distinct instances of the vegetation and the urban environment can be encoded. With the resulting system, the designer can efficiently vegetate landscape and city parks, alleys, gardens, patios and even single buildings by applying the corresponding shape grammar rules. Our results demonstrate the procedural design process on two practical example scenarios, each one covering a different scale and different contexts of planning. The first example illustrates a derivation of the Garden of Versailles and the second example describes the usage of high-level rule sets to generate a suburbia model.

title THE EMERGING DIGITAL STYLE: Attention shift in architectural style recognition

summary “Style” has long been an important index to observe the design thinking of designers in architecture. Gombrich (1968) defined style as a particular selection from the alternatives when doing things; Ackerman (1963) considered that a distiguishable ensemble of certain characteristics we call a style; Schapiro (1961) pointed out that style is constant forms, and sometimes the constant elements, qualities and expression; Kirsch (1998), Cha and Gero (1999) thought of style as a form element and shape pattern. As Simon and others referred to, style emerged from the process of problem solving, Chan (1994, 2001) ever devised a serious of experiments to set up the operational definitions of style, further five factors that relate to generating styles. Owing to that the greater part of sketches and drawings in the design process couldn’t be replaced by computer-aided design systems (Eisentraut, 1997), designers must shift between different problem-solving methods while facing different design problems. The purpose in this research is to discuss the influences of computer usage on style generation and style recognition: The employment of certain procedural factors that occurred in the design processes that using conventional media is different from the ones that using computer media? Do personal styles emerge while designers shifting between different media in the design processes? Does any unusual phenomenon emerge while accustomed CAD-systems designers recognizing a style?

source Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 860-866
summary The goal of the research described in this paper is to develop a computational model of the Medina of Marrakech in Morocco. The ultimate goal is to develop a system that could capture some of the characteristics of traditional Muslim cities fabric and use it in contemporary urban planning. Previous papers have proposed the use of three grammars to encode the spatial complexity of the Medina: the urban grammar, the negotiation grammar, and the housing grammar, and addressed the development of the urban grammar. This paper proposes a grammar to describe the formal structure of the houses, the first step in the developments of the remaining two grammars. It describes the set of rules and then illustrates its application in the generation of an existing house. The basic formal structure consists of three concentric rectangular rings with the patio in the middle. The location of the entrance and the staircase are fundamental for the definition of the basic layout.

title Dry-In House: A Mass Customized Affordable House for New Orleans
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 359-362
summary Dry-in house is a mass customized affordable housing system proposed for the reconstruction of New Orleans. The dry-in House gets the owner back to their home site quickly while providing the infrastructure an occupant needs (shelter, water, electricity). The owner is supplied with an inhabitable shell that is customizable before it is fabricated as well as onsite as the project is “fitted out” over time. The key concept is to allow families to participate in the design of their customized homes and to get people back to their home sites as quickly as possible and to give them the opportunity to finish and further customize their home over time. The project addresses inefficiencies and redundancies in emergency housing currently provided by FEMA. Primarily the dry-in House as its name implies provides a timely dried-in space which doubles as a customized infrastructure for the reconstruction of homes and neighborhoods. The project is designed to meet the $59,000 life cycle cost of the presently provided temporary housing, the notorious “FEMA Trailer”. However, the Dry-in House provides a solution that: a) Is permanent rather than temporary. The house will be finished and further customized over time rather than disposed of. b) Reoccupies the owner’s home site rather than a “FEMA ghetto” keeping the community together and functioning. c) Is mass customized rather than mass-standardized allowing the owner to have input on the design of their home. The design is a “starter home” rather than an inflexible and over-determined solution. This also has the benefit of giving variation to the reconstruction of New Orleans as opposed to the monotony of mass-production. d) Allows the owners to further customize their home over time with additional exterior finishes and the subdivision and fit out of the interior. By utilizing plate truss technology and associated parametric modeling software, highly customized trusses can be engineered and fabricated at no additional cost as compared to off-the-shelf trusses. This mass customization technology is employed to create the building section of each individual’s house. The truss is not used in its typical manner, spanning over the house; rather, it is extruded in section to form the house itself (roof, wall, and floor). Dry-in House exploits this building technology to quickly rebuild communities in a sensible manner. It allows for an increased speed of design and construction and most importantly it involves the owner in this process. The process has other benefits like reducing waste not only because it replaces the FEMA trailer which is expensive and disposable but also since the components are prefabricated there is more precision and also quality. The Dry-in House allows the owner-designer to “draw” the section of their new home providing them with a unique design and a sense of belonging and security. The design of the section of the house also provides them with spatial configurations customized relative to site conditions, program etc... Because of the narrow lot configuration of New Orleans, the design maximizes the roof as a source for natural ventilation and light for the interior of the house. In addition, the house is one room deep providing cross ventilation in all rooms minimizing reliance on artificial mechanical systems. The timely and efficient off site fabrication of building sections facilitate larger concentrations of volunteers on site at one time, thereby promoting a greater collective spirit among the community and volunteer workforce, a therapeutic event for the community as they participate in the rebuilding of their homes and city. With individualized building sections arriving on site, the construction process is imagined to be more akin to a barn raising, making possible the drying in of multiple houses in less than one day.

summary You and I were not born in the 1990’s thus our experience about the true modalities of circulation and communication that have substantially transformed the methods that form and inform us today, are not really “pure”. Why? Because we know how slow time was before the communication boom of this last decade and because some of us still believe that we must read to be inform and thus, visit a bookstore, library or friends house and get peeks inside a subject of matter. So experiencing life as we bypass the book _ that’s a story of a brand new era! Taking note of the enormous changes this era brings, is fundamental to our current pedagogic undertakings. We seek data about the differences that lie in the way individuals, which never knew a world before or between analogue and digital zones, process information. It signals a dramatic shift in cognitive realms that is deeply imbedded in our emerging socio-economic spheres. So, you say “hypothesizing that economic, technologic, and cultural fluxes fabricate new means to learn and think, is not a fresh idea”_ True. But, it led us to ask one fundamental question _What are the upcoming learning habits employed by the “post digital” society? We noted that the post digital generation is an avid cut, copy, paste society that is able to extract information from infinite resources and mix, remix in diversified modes, through time and in real-time. We think these abilities are strengths, which will permit students to multitask yet they strongly differ from the academic agendas that are concerned with meditative processes and qualitative interdisciplinary task. As aspiring academics interested in the reconfiguration of current pedagogic formats we seek a creative intervention for future design generations, one that can benefit both the upheavals of the cultural world and the integrity of the academic setting where a pedagogy that links extended fields of knowledge with shifting cognitive habits can emerge. In this arena where cognition plays an important role, our goals are challenging and difficult, especially in the beginning years when the foundations set forward leaves lasting impressions. Thus, letting go of familiar grounds and tuning to continual alterations of the immediate surroundings enables us to seek means that facilitate important readings for our current learning/teaching processes. Demystifying changes and embracing differences as design potentials for new interventions are basic programmatic elements that permit us to incorporate a rigorous research agenda in the design exercises. Our presentation will project the current state of our teaching modality and provide examples of current studio work. It will demonstrate how everyday rituals, journeys and research observations, are documented by a society that heralds a new academic setting.

title Redemptive Technologies II: the sequel (A Decade Later)
source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary Nearly ten years ago I published an article in the Dutch journal ARCHIS called "Redemptive Technologies." It derived from comments I made during a conference held in New Orleans in 1994. At that point the machine aesthetic associated with the "new technologies" generated by the computer had not established a precise formal vocabulary but were generating great excitement among the architectural avant-garde. It addressed the limits of the imagery and data produced by this machine and the simple but very political problem of cost and obsolescence. Now the millennium is well past and the somewhat apostolic fervor that accompanied the interaction of a very expensive consumer device with architecture has cooled. Discussion has generally moved from the titillating possibilities opened up by the device, many of which have so far not come to pass, to the sorts of hard and software available. An architectural language closely associated with the imagistic potential of new programs, biomorphism, has now come and gone on the runways of architectural taste. And yet, in recent articles rejecting the direct political effect of architectural work, the potential of new programs and virtual environments are proposed as alternative directions that our perpetually troubled profession may pursue. This paper will assess the last decade regarding the critical climate that surrounds cyber/technology. In the economic context of architectural education in which computers are still a central issue, the political issues that evolve will form a backdrop to any discussion. Furthermore, the problem of the "new" language of biomorphism will be reiterated as an architectural grammar with a 100-year history - from Catalan Modernismo and Art Nouveau, through Hermann Finsterlin and Eric Mendelsohn's projects of the 1920s, to Giovanni Michelucci and Italian work of the post-war, to Frederick Kiesler's Endless House of the late '50s, continuing through moments of Deconstructivism and Architectural Association salients, etc. These forms continue to be semantically simplistic and hard to make. Really the difference is the neo-avant-garde imagery and rhetoric involved in their continuing resurrection. Computer images, but also the ubiquitous machine itself, are omnipresent and often their value is assumed without question or proposed as a remedy for issues they cannot possibly address. This paper will underline the problem of the computer, of screens and the insistent imagistic formulas encourage by their use, and the ennui that is beginning to pervade the discipline after initial uncritical enthusiasm for this very powerful and expensive medium. But it will also propose other very valuable directions, those relating to reassessing the processes rather than the images that architecture engages, that this now aging "new" technology can much more resolutely and successfully address.

It utilizes shape grammars as a pedagogical tool for introducing the concept of design computing to graduate students of architecture without a background in computation theory. The teaching model has developed in two parallel run courses: 1-Introduction to Computational Logic in Design: a visual generative design tool shape grammar is used as a tool to teach design students computational logic, 2- Designing the Design: The design students are introduced with the new language and method of designing. Examples from the Computational Design graduate curriculum at Yildiz Technical University are given to illustrate explorations in this new teaching of design.

summary This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs

summary Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

summary A strong dichotomy exists between the factors of fluctuating natural orders apparent in the river, and the striation of the land by human historical and cultural influence. The installation exists as surface of influence between these forces. The form is informed by parameters of light, vista, material, and process through a method of digitally folding and perforating sheets of steel to enable a self structuring membrane which rises and falls from the plateau edge. A swath of prairie grasses, rising and falling in their own cycle, demarcates this edge. A screen of 15 weathering steel sheets stretches for 63’ across the boundary of the human order and the encroaching erosion of the natural realm. From the initial generation of geometry pairings, well “adapted” pairings are spliced from the parent and “bred” with similarly fit geometries. The fit of these pairs is based on the relationships between the form and the desired criteria of reflection, screening, and framing. To properly combine these pairings, several mutations occur (indicated in red).

title Experimental Approach in an Architectural Design Studio - How Digital Technologies Could Change a Design Process

summary This article communicates results of an experimental pedagogical strategy aiming at both, introducing and taking advantage of new technologies in an architectural design studio. One of the reasons for the notorious unfriendliness of CAD software to the design process comes from the attempt to imitate traditional pen and paper design on the computer. While the whole process could be completely different when performed in a digital environment offering powerful form generation and knowledge modelling possibilities. the proposed teaching method is based on the following principles: (1) emphasis on new methods of designing made possible by the use of computer; (2) communicating the design process, and not only the final result; (3) exploring parametric design for generation of different formal expressions of a design concept; (4) using visual programming to create inter-object relations, etc. A comparison of this experimental approach to other approaches used in design studios (digital or traditional), proves that the architectural results obtained are largely related to the chosen medium and the tools of work. In our opinion, this teaching approach proves to be promising for introducing considerable qualitative changes in the architectural profession, and this way in our built environment as well.
