summary	ZipShape is a universal method to fabricate single curved panels from any plain material without molds. The system uses two individually slotted panels that interlock when bent to the predefined curvature. As non-radial curves require individual teeth geometry, the method makes use of automated detailing with corresponding algorithms. ZipShape is a fusion of information processing and material processing based on comparatively simple software technology and standard workshop machinery. With help of case studies, this paper evaluates the method’s claim to be a variable and feasible solution for the realization of non-planar shape.

summary	“ZipShape is a universal method to fabricate single curved panels from any plain material without moulds” was the first statement of a paper presented at the Antwerp eCAADe conference in September 2008 (Schindler, 2008). In contrast, the paper at hand introduces ZipShape as a highly specific composite combining different materials and their characteristics. Between those two texts, a paradigm shift took place – from abstract geometrical concept to experiencing the inseparable relation of form and material behaviour. This second step of ZipShape-research was initiated by Swiss design office schindlersalmerón through several workshops with Fachschule für Holztechnik Hamburg, CITA at Royal Academy of the Fine Arts Copenhagen, Bern University of Applied Sciences BFH–AHB Biel and The Detmold School of Architecture and Interior Design.

summary	The paper discusses mathematical form generation as an academic methodology to develop new approaches to architectural design. The academic design studio ‘Math objects’ investigates the relationship between complex 3d-surfaces and mathematics in order to expand the formal repertoire of architecture. It claims that the process of form generation can be seen as an autonomous entity, which is independent from an overall strategy or any a priori meaning. Architecture has always originated from a concept, eventually progressing towards a certain form. This methodology has been reversed. The paper discusses two studios undertaken in the last year, led by Daniel Baerlecken and Olaf Kobiella at the TU Braunschweig, Germany.

summary	Making double curvature surfaces in architectural design is nontrivial and presents many challenges. Design and fabrication of these complex shapes requires systematic approaches. Most current design and fabrication processes distribute adaptable patterns over modulated variable surfaces. But to produce variation with this method means many machining hours and a budget that a conventional architectural project cannot afford. An alternative method to achieve such complex shapes would be to overlap identical elements on a grid. This paper presents an approach to fabricate such complex surfaces from the repetition of a series of identical elements.

title	Digital design and manufacture based on Chiloean boats
source	International Journal of Architectural Computing vol. 6 - no. 3, pp. 317-333
summary	This paper proposes a design methodology for the manufacture of complex, double-curved surfaces based on the digital reconstruction of traditional structural and constructive elements of Chiloean boats. It also suggests a beneficial association between digital design and CAD CAM for manufacture using locally crafted construction techniques. The incorporation of innovated contemporary digital design and fabrication tools into traditional construction systems, aims to optimize and perpetuate traditional artisanal craft construction of complex shapes developed in the south of Chile. The importance of this research in budget-restricted economies, lies in the possibility of applying local construction and assembly techniques to new sophisticated designs that may satisfy the country's architectural needs. Scale models are used to record the design process and constructive development while information flow charts document the design methodology for the construction of complex geometries.

summary	There is a close relation between building design and fabrication. However still it is mostly a sequential process where the fabrication with its geometric chances and limitations is only to a small extend taken into account in early design phases. In this paper we describe a protoype form work project, realized out of styrofoam cut out with a CNC hot wire-cutting system and coated with the Claraporon coating system. Due to the linear nature of hot wire cutting the surfaces that can be created are ruled surfaces. They are discussed in a more general way as well as first exercises with ruled surfaces in teaching.

title	Progressions in Defining the Digital Ground for Component Making
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 57-64
summary	Terms digital and computation, once accepted as emergent understandings in design, became commonly known and used in recent years. Transformation of techniques from analog to digital created a shift in the understandings as well as products of design. Digital design exploration enabled the designers’ exposure to variety and richness. Increasing number of digital tools became easily-accessible. Thus design thinking in both practice and academia was transformed. Computation, via increasing power and speed of processing, offers mass information execution. Once this power was utilized to inform the discrete pieces of design, “component making” quickly became one of the trends in architectural design. Idea of components transformed the enclosing forms of architecture into subdivision surfaces which act as fields for components to aggregate on. While there has been a great interest in creating variety via manipulation of components as individual members, the characteristics of the surfaces became overlooked via common use of parametric (UV) subdivision. This paper, with a critical look at the current component field generation techniques, focuses on alternative methods of transforming a surface into a digital ground for component aggregation. Series of studies address and deal with various pitfalls of component design and application on software-dictated UV subdivision surfaces. Studies aim to release the component design logic from being software-specific by creation and use of customized digital tools and scripts.

title	Deconstructing Materiality: Harderials, Softerials, Minderials, and the Transformation of Architecture
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 367-376
summary	This paper presents a deconstructionist close reading of the conventional discourses about materiality by forwarding a triadic framework of harderials, softerials and minderials. The discourse draws from the Derridan notion of différance in articulating the fundamental difficulty in understanding materiality. Taking the discourse about materiality into the digital realm, a critical discussion of softerials (BREP Solids, Polynomial Surfaces and Isomorphic Polysurfaces) and their implication to architecture are presented. Questions about a possible material-envy and materiality-complex in architectural profession are also raised. Different binary strategies by which softerials are relegated by architects to a secondary status of “media” are exposed.

summary	Composite structures consist of high strength carbon threads held together in a matrix of epoxy resin or thermoplastics. Surfaces made from these materials are typically 10 times lighter and 1.5 times stronger than aluminum. Both simple and highly contoured shapes possessing extreme strength can be produced using a computer controlled fiber placement machine (FPM). These incredibly thin, corrosion resistant membranes require little or no supplemental support to manage loads and enclose space. The computer’s ability to determine the precise location of each fiber strand in a fiber placed part also facilitates unprecedented control of its aesthetic and functional properties. Fiber placement technology integrates building components that would normally be separated into clearly distinct systems. Here ornament, structure and cladding are collapsed into one material process. This paper explores the architectural potential of a technology normally reserved for aerospace applications through research conducted in close collaboration with fiber placement engineers at Automated Dynamics in Schenectady, New York (ADC).

title	Spatial Augmented Reality for Architecture Designing and planning with and within existing buildings
source	International Journal of Architectural Computing vol. 6 - no. 1, pp. 41-58
summary	At present, more than half of all building activity in the German building sector is undertaken within existing built contexts. The development of a conceptual and technological basis for the digital support of design directly on site, within an existing building context is the focus of the research project "Spatial Augmented Reality for Architecture" (SAR). This paper describes the goals achieved in one aspect of the project: the sampling of colors and materials at a scale of 1:1 using Augmented Reality (AR) technologies. We present initial results from the project; the development of an ad-hoc visualization of interactive data on arbitrary surfaces in real-world indoor environments using a mobile hardware setup. With this, it was possible to project the color and material qualities of a design directly onto almost all surfaces within a geometrically corrected, existing building. Initially, a software prototype "Spatial Augmented Reality for Architecture-Colored Architecture" (SAR-CA) was developed and then assessed based on evaluation results from a user study.

title	Structuring a Generative Model for Urban Design: Linking GIS to Shape Grammars
doi	https://doi.org/10.52842/conf.ecaade.2008.929
source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 929-938
summary	Urban Design processes need to adopt flexible and adaptive procedures to respond to the evolving demands of the contemporary city. To support such dynamic processes, a specific design methodology and a supporting tool are needed. This design methodology considers the development of a design system rather than a single design solution. It is based on patterns and shape grammars. The idea is to link the descriptions of each pattern to specific shape rules inducing the generation of formal solutions that satisfy the pattern. The methodology explores, from the urban designer point of view, the capacity of a shape grammar to codify and generate urban form (Duarte et al, 2007). This paper defines the ontology of urban entities to build on a GIS platform the topology describing the various components of the city structure. By choosing different sets of patterns the designer defines his vision for a specific context. The patterns are explicated into shape rules that encode the designer’s interpretation of the pattern, and operate on this ontology of urban entities generating solutions that satisfy the pattern’s concept. Some examples of the topological relations are shown.

summary	In this paper we present the development of a GIS tool kit for the socioeconomic valuation of urban areas towards the creation of sustainable communities, describing the project context, development process, the tool kit’s structure, its main tools and initial feedback from its use. We then present the plan for training sessions and pilot projects where the tool kit is going to be used, and conclude with the discussion of the development of a single integrated tool to be used beyond the life of the ‘i-VALUL’ project. This project was supported by the UCL led UrbanBuzz programme within which UEL is a prime partner.

title	Computing Different Projections of a Polyhedral Scene from a Single 2D Sketch
doi	https://doi.org/10.52842/conf.ecaade.2008.195
source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 195-200
summary	This paper presents the development of a tool which is capable of compute several projections of a polyhedral scene from a single axonometric or perspective projection. This projection is hand-drawn and may be incomplete. This sketch can be rotated with a kind of trackball and the tool computes in real-time new projections. In that way the designer can choose another view from which he is able to control and complete the sketch and carry on designing. So this tool can be useful for exploring architectural forms in the early phases of the design process. Unlike others freehand sketching interfaces, the system does not operate any reconstruction in 3D. Everything is computed in a 2D world.

title	A GA-based Multi-Objective Optimization Model for Location Planning of Urban Parks and Open Spaces A Case Study on Dhaka City
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	In this paper, we present a new multi-objective location model for urban parks and open spaces (POSs) planning. We developed a Genetic Algorithm (GA) based multi-objective optimization model (GAMOOM) to derive optimum locations of POSs by considering four incommensurable objectives with the provision of POSs near: 1) densely populated areas, 2) air polluted areas, 3) noisy areas, and 4) areas without open spaces. The success of the model is presented through its application as a case study on Dhaka City. Obtained results indicate that the model can successfully provide optimum location of required POSs. The findings from this study also signify that optimum location of POSs obtained by utilizing only the second objective is substantially different than that of others. Moreover, there is also difference in optimum location of POSs by taking into account only the third objective when compared with others. Therefore, considering single objective cannot give optimum results for good POSs planning. So, it is verified that POSs should be planned by optimizing multiple objectives instead of single objective. The outcome of this multi-objective GAMOOM model does have an implication on how POSs should be designed and managed by the planning authority for not only sustainable environment but also better quality of life in a city.

title	Programming As an Evolutionary Concept for Architectural Education: From natural systems to computer science materialization to emergent and evolutionary embedded architectural design

summary	Logic and evolution in ontogenetic processes for Architectural design was the title for a summer program taught at the Escuela de Arquitectura of the Universidad Anahuac from June to July 2008 in the State of Mexico, Mexico. Every single result in architectural design follows logical steps enclosed in the design processes. These logical processes evolve through space-time sequences in order to generate a diversity of possible solutions. In Biology an ontogenetic process refers to the development of an individual organism, anatomical or behavioral feature from the earliest stage to maturity. Following this development criteria students were encouraged to understand the main logics of natural and physical systems through the aid of computer programming. These logics must be understood as tridimensional geometries digitally generated. Right from the beginning all processes generated during the explorations and investigations had to be visualized as integral design performances. The integral design system must embedded structure, function, form and material capacities through the aid of computer programming, digital fabrication technologies and material assembling techniques. It is important to note that final prototypes had to demonstrate the diversity of capacities of the whole system in order to automate the components in evolution.

title	Structural Analysis as Driver in Surface-Based Design Approaches
source	International Journal of Architectural Computing vol. 6 - no. 1, pp. 19-39
summary	This research argues for novel strategies to integrate structural analysis data in architectural design. Instead of a linear procedure of analysis, synthesis, evaluation and post-rationalization a synthesis/evaluation loop is installed which embeds structural analysis data as design driver from early on. The approach regards structural performance as one design criteria within a network of different requirements. An equilibrium of multiple parameters is aspired to instead of a single-parameter-optimum. The research is conducted via a custom-made digital interface between 3d modelling software and an application for structural analysis of space frames. The information exchange provides the basis for successive strategies within a collaborative design process of spatial roof structures: negotiation of an overall form and a multi-dimensional improvement of space frame topologies by a Genetic Algorithm (GA).

title	An Energy Centric Approach to Architecture: Abstracting the material to co-rationalize design and performance
doi	https://doi.org/10.52842/conf.acadia.2008.072
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 72-81
summary	This paper begins by exploring matter as an aggregated system of energy transactions and modulations. With this in mind, it examines the notion of energy driven form finding as a design methodology that can simultaneously negotiate physical, environmental and fabrication considerations. The digital workspace enables this notion of form finding to re-establish itself in the world of architecture through a range of analytic tools that algorithmically encode real world physics. Simulating the spatial and energetic characteristics of reality enables virtual “form generation models that recognize the laws of physics and are able to create ‘minimum’ surfaces for compression, bending [and] tension” (Cook 2004). The language of energy, common in engineering and materials science, enables a renewed trans-disciplinary dialogue that addresses significant historic disjunctions such as the professional divide between architects and engineers. Design becomes a science of exploring abstracted energy states to discover a suitable resonance with which to tune the built environment. ¶ A case study of one particular method of energy driven form finding is presented. Bi-directional Evolutionary Structural Optimization (BESO) is a generative engineering technique developed at RMIT University. It appropriates natural growth strategies to determine optimum forms that respond to structural criteria by reorganizing their topology. This dynamic topology response enables structural optimization to become an integrated component of design exploration. A sequence of investigations illustrates the flexibility and trans-disciplinary benefits of this approach. Using BESO as a tool for design rather than purely for structural optimization fuses the creative approach of the architect with the pragmatic approach of the engineer, enabling outcomes that neither profession could develop in isolation. The BESO case study alludes to future design processes that will facilitate a coherent unfolding of design logic comparable to morphogenesis.

title	Topological Method of Construction of Point Surfaces as Physical Models
source	Proceedings of the 8th European Architectural Endoscopy Association Conference
summary	The shape of architectural objects in general can be treated as an envelope – a two dimensional surface embedded into three dimensional space. We directly perceive only the surface as a synthesis of sequential “photo snaps” – the two dimensional imprints on a retina – a concave screen inside of our eyes. In 15th century Italian architect and theorist L. B. Alberti claimed that the architecture consists in the outlines and the structure (lineamenta et structura in the original Latin text). The visible shape (outlines) exists only because a directly not perceived structure determines it. Like Alberti, the modern mathematical theories of form distinguish the shape as an exterior surface and the form itself as an internal structure. This subtle difference becomes a very important subject in the relationship between a virtual and a physical model in the studies of architectural endoscopy.

summary	This paper discusses multiple aspects of the city through examples of artistic interventions which see the city as complex and dynamic layers in constant change. This paper investigates the spatial configuration changes of São Paulo city in material surfaces as facades and walls. The understanding of urban surfaces as "'mediative' spatiality" (Ferrara, 2008) assigns communication categories to urban surfaces; the visual condition is discussed in this paper.
