title	The Medium Is the Matter: Critical Observations and Strategic Perspectives at Half-time
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 129-136
summary	This paper critically re-views the professional impact and functionality of the pervasive digital ‘matter’ we have come to believe we can no longer do without. On the basis of a playful exploration of the first ‘half-century’ of our digital age, an attempt is made to draw new perspectives for the next ’level’ of our digital culture in a broader (multi)media perspective and more specifically: the domains of Architecture. To stimulate an open-minded ‘second-half’ debate, the paper puts forward some potentially promising (and hopefully provocative) conceptions and strategies for imaginative interface applications and game-based architectural study initiatives. Furthermore, the paper proposes the establishment of a new cultural platform for the exchange of Critical Digital hypotheses and the evolvement of visionary design concepts through creative digital innovation, with the (inter)active involvement of older and younger team-players…

title	Certain assumptions in Digital Design Culture: Design and the Automated Utopia
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 137-148
summary	Much of the research efforts in computational design for Architecture today aim to automate or bypass the production of construction documents as a means of freeing designers from the sticky and inconvenient contingencies of physical matter. This approach has yielded promising questions and applications, but is based on two related assumptions that often go unnoticed and that I wish to confront: 1. Designers are more creative if the simulations they rely on engage only with the superficial aspects of the objects they design (rather than with their structural and material-specific behaviors) and 2. The symbolic 3-D environments available in current design software are the ideal media for design because of their free nature as modeling spaces. These two assumptions are discussed both as cultural traits and in their relation to digital design technologies. The work presented is a step towards the far-sighted goal of answering the question: how can computation enable new kinds of dialogue between designer, design media and construction in a design process? In concrete, this paper proposes a critical framework for discussing contemporary digital design practices as a continuity –rather than as a rupture- of a long-standing tradition in architecture of separating design and construction.

title	CeramiSKIN: Biophilic Topological Potentials for Microscopic and Macroscopic Data in Ceramic Cladding
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 65-76
summary	CeramiSKIN is an inter-disciplinary investigation examining recursive patterns found in organic matter. Through the use of digital capture and translation techniques, these biophilic systems may serve as topological generators for structural and ornamental consequences well-suited to mass-customizable ceramic cladding systems for architecture. Digital information is acquired through laser scanning and confocal electron microscopy, then deformed using particle physics engines and parametric transformations to create a range of effects promulgated through digital fabrication techniques. This inquiry is primarily concerned with two questions: Is it possible that natural systems may be digitally captured and translated into biophilic structural forms and/or ornamental effects that may foster beneficial responses in humans? / Since natural orders eschew rigid manifold geometries in favor of compound plastic shapes, is it possible to fabricate mass-customized, large-scale biophilic ceramic cladding from organic digital data?

summary	While conventional information displays are still effective, a lack of integration between descriptive and contextual information means they cannot be used independently of additional external information. New digital systems such as Google Maps are increasing in popularity. Unfortunately these present some limitations in terms of understanding both route and survey information, and in particular navigation and orientation, such as intuitively understanding a plan view no matter which way one is facing, so visitors can quickly and intuitively learn how to get to specific buildings or to specific facilities. Digital systems may also alienate older and non computer literate users; and they display contextual information inside an interface which limits the possible range of interaction methods offered by physical interaction. Our solution was to create a 3D physical model that one could spin, which would in turn display digital panoramas that spun in rotational alignment with the physical city model. Further, the user could place category tokens in intersections of the city model, which would bring up digital panoramas on the screen and highlight facilities linked to the category chosen. Rotating the token would also rotate the digital panorama.

title	Information-matter hybrids: Prototypes engaging immediacy as architectural quality
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 105-110
summary	‘Immediate Architecture’ is an exploratory investigation into possibilities of immediate interactive and constructive interaction with the built environment supported by digital technologies. Aim is to realize interactive reconfigurable architectural objects that support their informational and material reconfiguration in real-time. The outcome is intended to become a synergetic amalgam of interactive architecture, parametric design environment, automated component fabrication and assembly. To this end, computational and material strategies are developed to approach the condition of immediate architecture and applied in real-world prototypes. A series of developed techniques are presented, ranging from realtime volumetric modeling, behavioral programming and meta-application protocol to streaming fabrication and dynamic components for interactive architecture.

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	When The Going Gets Tough, The Pluripotent Get Going: Resilient Developmental Models
doi	https://doi.org/10.52842/conf.acadia.2008.088
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, 88-93
summary	Mechanisms of biological development, such as in embryogenesis, offer promising models for resilient architectural systems well-suited to volatile or unpredictable contextual conditions. The resilience of embryonic development as a process is such that successful development—“success” defined here as that which results in the birth of an organism that can survive—can sustain extreme shifts in a normal developmental process, triggered by mutations, environmental pressures, injury, or experimental intervention. More specifically, biological development combines mechanisms of standardization with mechanisms of customization to create open-ended or what biologists call pluripotent systems—poised (“-potent”) to develop into a wide range (“pluri-”) of potential forms—which we can endeavor to reproduce mimetically. ¶ This paper considers biomimesis less a matter of replicating these developmental mechanisms physically or formally, but rather borrowing aspects of the mechanisms’ operation in order to test project outcomes digitally. The discipline of developmental biology affords a virtually ready-made conceptual framework and terminology to guide an open-ended digital methodology, in the hope of incorporating increasing degrees of resilience into the resulting design work. Searching for a capacity to sustain a similar fluidity of differentiation afforded by organisms in early development, we explore a pluripotent architecture for which differentiation might occur over time, and which might be better able to absorb volatility.

title	Dynamic Design Matter[s]: Practical considerations for interactive architecture
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 49-56
summary	This paper explores the concept of interactive architecture. The first section begins by formulating a daring vision of a radically new kind of architecture. In the second chapter this vision is further elaborated upon, by proposing a generic approach towards practically accomplishing the originally formulated theoretical concept. Opportunities and threats that emerge from this vision and approach are discussed in the third section and eventually, in section four and five, the proposed approach is brought to practical applications and illustrated with a number of experimental building component examples that all together include all necessary features to create a complete large scale architectural object. All projects and explorations have been conducted as part of the Hyperbody group’s research at the Delft University of Technology and have been inspired by group’s director, prof. Kas Oosterhuis.

summary	Narratives—public and private are the stuff of design. This commonplace truism is often forgotten in the buzz, boom and confusion surrounding the development of digital media; digital media seem to offer a “virtual” alternative to such stuff; as such, the current Romance with Digital Media is nothing but a weak revival of primitive mentalism.

title	The teleplastic abuse of ornamentation
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 383-392
summary	Is it possible that psychoanalysis, a discipline that allegedly deals with abstract or invisible entities, and entomology, a discipline that predominantly taxonomizes insects by type, can offer us an insight into the nature of digital design processes and emergent material phenomena? One of Roger Caillois’ most controversial psychoanalytic theories, “teleplasty,” shows that psychoanalysis and entomology can indeed suggest an alternative perspective of how bodily or other material substances are initially fabricated by insects and how they can further transform. In several of his case studies, Caillois claims alliances between material and psychical structures in his psycho-material teleplastic theorem and eventually questions spatial distinctions: distinctions between geometry and material, purpose and function, cause and effect, between the imaginary and the real. Can digital media help us redefine the static relationship between a window and a wall as an interaction of chemical substances rather than a process of assembling joints and components? Can we perceive material, not as an application to predetermined geometries, but as an inherent condition, a subatomic organization of matter that precedes geometry? The aim of this paper is to problematize such distinctions as a discussion emerging through the prolific use of digital design processes.

summary	Biological processes, computing and design make an inconvenient mix, a mix that challenges us to broaden our academic horizons at a time when we are thirsty for creative solutions to unprecedented global problems and opportunities. More than a mixture, it is about forming rhizomatic connections between these three systems of knowledge, brought together through design, mediated by computing and inspired by the wisdom ensconced in biological processes that have evolved over billions of years. The last few years together represent a watershed time for ACADIA. Themes ranging from digital fabrication, smart environments, expanding bodies, and synthetic landscapes have been taken up in the recent past. This year’s conference marks yet another year of pushing the envelope with a subject matter that is still on the frontiers of the emerging (and emergent) knowledge. ACADIA is proud to play a vanguard role in leading and facilitating this discourse. To this end, the outstanding team of conference chairs has put together a unique and exciting program. I would like to thank the chairs for their boldness, hard work and resourcefulness in bringing together a remarkable array of people, things, systems, and topics to the table. All evidence points to the emergence of ACADIA as THE forum for vanguard explorers from multiple disciplines. I hope that the seeds of discourses sown at this remarkable conference at the University of Minnesota will grow into significant movements in the future. Thank you!

source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 287-294
summary	What is videogame matter? This essay examines the matter of videogames in relationship to architectural design, and advances a definition that videogame matter is: meta, modular, indexical, and distributive. These attributes support an argument that the materiality of the videogame has a markedly different set of properties than the matter of the physical world. A definition of videogame matter is critical to understanding the value of design within virtual environments, which then aids architects and designers utilizing the immersive environments of the videogame for representation, design and collaboration.

title	ARCHITECTURE ‘in computro’ - Integrating methods and techniques
doi	https://doi.org/10.52842/conf.ecaade.2008
source	26th eCAADe Conference Proceedings [ISBN 978-0-9541183-7-2], Antwerp (Belgium) 26-29 September 2008, 968 p.
summary	The presence of both visible and hidden digital resources in daily life is overwhelming and their presence continues to grow exponentially. It is surprising how little the impact of this evolution is questioned, especially in education. Reflecting on past experiences of this subject to learn for the future seems rarely to be done, and the sheer fact that a digital method exists is often seen as sufficient justification for its use. Are these the perceptions of serious misgivings or isolated views that circulate in the educational world and beyond? We would suggest that the eCAADe (Education and Research in Computer Aided Architectural Design in Europe) and its conferences provide the ideal forum to provide answers in this debate. For the first conference in what is to be the next quarter century of the existence of eCAADe, a theme was chosen that could easily include all aspects of this debate: ARCHITECTURE ‘in computro’ , Integrating methods and techniques It seems a bit vulgar to use a dog-Latin phrase ‘in computro’ for such a serious matter but at least it now has a place between ‘in vivo’ and ‘in vitro’. For more than 25 years CAAD has been available, and has been more and more successfully used in research and commercial architectural practice. In education, which by definition should prepare students for the future, the constantly evolving CAAD metaphor is provoking a challenge to cope with the ever expanding scope of related topics. It is not surprising that this has led to differing opinions as to how CAAD should be taught. Questions such as how advanced research results can be incorporated in teaching, or if the Internet is provoking self-education by students, are in striking contrast with the more fundamental issues such as the discussion on analogue versus digital design methods. Is CAAD a part of design teaching or is it its logical successor in a global E-topia? Although the E of education is a prominent factor in the ‘raison d’être’ of the organisation, the papers presented at this conference illustrate that eCAADe is open to all other relevant contributions in the area of computer-aided architectural design. It will be a fortunate coincidence that this exchange of knowledge and opinions on such state-of-the-art subjects, will be hosted by the The Higher Institute of Architectural Sciences, Henry van de Velde, located in the historical buildings of the Royal Academy of Fine Art established since the founding of the academy in 1662.

title	Oublier Domino: On the Evolution of Architectural Theory from Spatial to Performance-based Programming
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 393-402
summary	The conception of the architect as form-giver has since historical times dominated the field of architecture. It is precisely this image which has devalued material practice in the distinction between form and matter consistently inherent in architectural discourse. Recent technological developments in the field of design computation, coupled with environmental concerns and philosophical debates have contributed to the shift in focus from form, as the exclusive object of design practice to matter and materials as an alternative approach to the conception of form. Such a shift calls for a reorientation of existing protocols for design generation. Design based upon performance appears to justify and make sensible computational design processes that integrate material properties with structural and environmental constraints. These processes, as demonstrated here, contribute to the elimination of traditional architectural typologies replaced with spatial organization driven by need and comfort. This paper proposes a new approach in design where processes of formgeneration supporting sustainable design solutions are directly informed by structural and environmental constraints. Computational models are developed and implemented that incorporate data-driven form generation. Fabrication tools and technologies are customized to include material properties and behavior. The projects illustrated in this paper are currently on display at the Museum of Modern Art.

summary	Through the formation of bio-chemical information networks natural materials possess efficient processes of self-organization, adaptability, regeneration and decomposition. This performative excellence has lead science to draw behavioral models from nature implementing biomimmicry (Benyus 1998) in the pursuit of material systems optimization. Design disciplines influenced by this course are integrating living organisms as models of efficiency through bionic systems ever more into their discourse. Architecture, influenced by this tendency, is becoming progressively more aware of the vast benefits that biomimetics can yield particularly in the development of ecologically sensitive systems. Yet, the emerging incorporation of bionics into architecture is differing largely to that within the sciences by centering almost exclusively in form (geometrical pattern) generation. This paper analyzes a rising material design research methodology implementing biomimetics: matter-form parametrics based on bio-physical properties’ data. Specific study of the incorporation of broad-scalar scientific imaging into the formulation of explorative parametric grammar for the development of material systems is analyzed through a bio-synthetic polymer based wall system (SugarWall, Gensler+Gutierrez 2006b). The incorporation of broad scalar imaging and material interdependencies is propelling the emergence of new programming tactics that will affect bio-material systems architectural research.

summary	“A city can not be designed” Watanabe [1]: our ambition can be at the maximum to guide someway and in some part its growth. So as planners need tools to aid an open design with uncertain goals. This research group beginto develop such a tool at high level of abstraction (Fioravanti 2008), with theaim of investigating the potentiality of a collaboration among complementary research domains. The present work reports about early implementation results of an innovative approach developed by the authors, for representation of design knowledge. It has been identified in the Urban Design Ontology (Montenegro and Duarte 2009) some design entities and their internal relationships that have been formalized and visualized by means of an intuitive interface. As a matter of fact, this approach, by means of inference engines allows coherence’s check and constraint verification, pointing out incompatibility between initial design program and each partial specialist design solution and/or the overall shared one.

summary	A convenient method for creating accurate 3D urban models without expensive survey equipment is developed by introducing digital photogrammetry. As a matter of logic, the 3D models for urban landscape simulations are expected to limit errors to several dozen centimeters. The proposed method is examined in order to reproduce the actual urban landscape and to provide accuracy that is sufficient to meet the theoretical requirement.

title	Poetics of performative space
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 403-417
summary	My project concerns subjectivation, performativity and embodiment, as inflected by notions of process and field. These questions were inspired by recent work in the margins of experimental performance, sound arts, computational media, and philosophy of process. They are informed by, and critically respond to Leibniz’s continuous substance, Whitehead’s “unbifurcated” process ontology, and Petitot’s approach to morphogenesis. Beginning with a concern with the materiality of writing, the project explores the ethico-aesthetics of touch and movement, and poetic architecture or installation events as sites for speculative action. The kind of events I describe, are collective, co-present, embodied, and a-linguistic. The potential for physical contact is a condition for the collective embodied experiences needed to conduct experimental phenomenology. Our events are designed for four or more participants, three to destabilize dyadic pairing, and lower the threshold to improvising being in that space, and a fourth for potential sociality. Having dissolved line between actor and spectator, we may adopt the disposition of an agent of change, or equally a witness of the event. Relinquishing also a categoreal fixation on objects in favor of continua, we inhabit ambient environments thick with media and matter that evolve in concert with movement or gesture.

title	Energy Puppet: An Ambient Awareness Interface for Home Energy Consumption
source	Digital proceedings of the 7th International Workshop on Social Intelligence Design (SID 2008), School of Architecture, Universidad de Puerto Rico, San Juan, Puerto Rico.
summary	The Energy Puppet is an ambient display device that provides peripheral awareness of energy consumption for individual home appliances. The display produces different “pet-like” behavioral reactions according to energy use patterns of the appliances to give homeowners an indication of their energy consumption status. The puppet would raise its “arms” in victory to display normal consumption rate, or its “eyes” would change color to red and “roar” to warn the homeowners when the specific appliance reaches dangerously high consumption rates. The assumption is that the awareness of energy consumption could affect how people consume and control energy use in their households. This paper describes the usage scenarios and the design and implementation of Energy Puppet and discusses future research directions.

title	Automated Cost Analysis of Concept Design BIM Models

summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.
