title Rethinking the Space of Intelligent Environments
source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 377-382
summary Technologies are not mere exterior aids but interior changes of consciousness that shape the way the world is experienced. As we enter the age of ubiquitous computing, where computers are worn, carried or embedded into the environment, we must be careful that the ideology the technology embodies is not blindly incorporated into the environment as well. As disciplines, engineering and computer science make implicit assumptions about the world that conflict with traditional modes of cultural production. Space is commonly understood to be the void left behind when no objects are present. Unfortunately, once we see space in this way, we are unable to understand the role it plays in our everyday experience. In this paper, I argue that with the realization of the vision of ubiquitous computing, the fields of computer science and engineering reify the dominance of abstract space in real space. A new approach to the design of computing systems is necessary to reembody space. The social nature of the interface allows us to situate it within Henrí Lefebvre’s notions of space, providing new tools for thinking about how computing practice engages space as well as opening avenues to rematerialize the environment through embodied interaction.

title Creative Design Between Representation and Simulation
source CAAD | INNOVATION | PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 11-12
summary Milestone figures of architecture all have their different views on what comes first, form or function. They also vary in their definitions of creativity. Apparently, creativity is very strongly related to ideas and how they can be generated. It is also correlated with the process of thinking and developing. Creative products, whether architectural or otherwise, and whether tangible or intangible, are originated from ‘good ideas’ (Elnokaly, Elseragy and Alsaadani, 2008). On one hand, not any idea, or any good idea, can be considered creative but, on the other hand, any creative result can be traced back to a good idea that initiated it in the beginning (Goldschmit and Tatsa, 2005). Creativity in literature, music and other forms of art is immeasurable and unbounded by constraints of physical reality. Musicians, painters and sculptors do not create within tight restrictions. They create what becomes their own mind’s intellectual property, and viewers or listeners are free to interpret these creations from whichever angle they choose. However, this is not the case with architects, whose creations and creative products are always bound with different physical constraints that may be related to the building location, social and cultural values related to the context, environmental performance and energy efficiency, and many more (Elnokaly, Elseragy and Alsaadani, 2008). Remarkably, over the last three decades computers have dominated in almost all areas of design, taking over the burden of repetitive tasks so that the designers and students can focus on the act of creation. Computer aided design has been used for a long time as a tool of drafting, however in this last decade this tool of representation is being replaced by simulation in different areas such as simulation of form, function and environment. Thus, the crafting of objects is moving towards the generation of forms and integrated systems through designer-authored computational processes. The emergence and adoption of computational technologies has significantly changed design and design education beyond the replacement of drawing boards with computers or pens and paper with computer-aided design (CAD) computer-aided engineering (CAE) applications. This paper highlights the influence of the evolving transformation from Computer Aided Design (CAD) to Computational Design (CD) and how this presents a profound shift in creative design thinking and education. Computational-based design and simulation represent new tools that encourage designers and artists to continue progression of novel modes of design thinking and creativity for the 21st century designers. Today computational design calls for new ideas that will transcend conventional boundaries and support creative insights through design and into design. However, it is still believed that in architecture education one should not replace the design process and creative thinking at early stages by software tools that shape both process and final product which may become a limitation for creative designs to adapt to the decisions and metaphors chosen by the simulation tool. This paper explores the development of Computer Aided Design (CAD) to Computational Design (CD) Tools and their impact on contemporary design education and creative design.

title Shape Exploration in Design: Formalising and Supporting a Transformational Process
source International Journal of Architectural Computing vol. 6 - no. 4, 415-433
summary The process of sketching can support the sort of transformational thinking that is seen as essential for the interpretation and reinterpretation of ideas in innovative design. Such transformational thinking, however, is not yet well supported by computer-aided design systems. In this paper, outcomes of experimental investigations into the mechanics of sketching are described, in particular those employed by practicing architects and industrial designers as they responded to a series of conceptual design tasks. Analyses of the experimental data suggest that the interactions of designers with their sketches can be formalised according to a finite number of generalised shape rules. A set of shape rules, formalising the reinterpretation and transformations of shapes, e.g. through deformation or restructuring, is presented. These rules are suggestive of the manipulations that need to be afforded in computational tools intended to support designers in design exploration. Accordingly, the results of the experimental investigations informed the development of a prototype shape synthesis system, and a discussion is presented in which the future requirements of such systems are explored.

title Gulliver in the land of Generative Design

summary The current trend in architectural design towards architectural computing has been treated both from a philosophical standing point and as an operational systems’ problem, in a quest for explications which could at last break ground for a more broad development and adoption of design tools. As Kostas Terzidis (2007) puts it, the intuitiveness that architects have put on so high a pedestal seems to be the central issue to be dealt with by both views. There seems to be no apparent shortcut toward the reconciliation between traditional practice and new media and most certainly it is not only a problem of interface design, but one of design method clarification and reinterpretation of those methods into computing systems. Furthermore, there’s no doubt left as to whether computing systems can generate such new patterns as to impact our own understanding of architecture. But even if computer algorithms can make possible the exploration of abstract alternatives to an abstract initial idea, as in Mathematica and Processing, the issue of relating abstract and geometric representations of human centered architecture lays in the hands of architects, programmers or, better yet, architect-programmers. What seems now to be the relevant change is that architectural design might escape from the traditional sequence embedded in the need – program – design iterations – solution timeline, substituted by a web of interactions among differing experimental paths, in which even the identification of needs is to be informed by computing. It is interesting to note that the computational approach to architectural design has been praised for the formal fluidity of bubbles and Bezier shapes it entails and for the overcoming of functionalist and serialization typical of modern architecture. That approach betrays a high degree of canonic fascination with the tools of the trade and very little connection to the day to day chores of building design. On the other hand, shall our new tools and toys open up new ways of thinking and designing our built landscape? What educational issues surface if we are to foster wider use of the existing technologies and simultaneously address the need to overtake mass construction? Is mass customization the answer for the dead end modern architecture has led us to? Can we let go the humanist approach begun in Renascence and culminated in Modernism or shall we review that approach in view of algorithmic architecture? Let us step back in time to 1726 when Swift’s ‘Travels into Several Remote Nations of the World by Lemuel Gulliver’ was first published. In Swift’s fierce critic of what seemed to him the most outrageous ideas, he conceived a strange machine devised to automatically write books and poetry, in much the same generative fashion that now, three centuries later, we begin to cherish. “Every one knew how laborious the usual method is of attaining to arts and sciences; whereas by his contrivance, the most ignorant person at a reasonable charge, and with a little bodily labour, may write books in philosophy, poetry, politicks, law, mathematics and theology, without the least assistance from genius or study. He then led me to the frame, about the sides whereof all his pupils stood in ranks. It was twenty foot square, placed in the middle of the room. The superficies was composed of several bits of wood, about the bigness of a dye, but some larger than others. They were all linked together by slender wires. These bits of wood were covered on every square with paper pasted on them; and, on these papers were written all the words of their language in their several moods, tenses, and declensions, but without any order. The professor then desired me to observe, for he was going to set his engine at work. The pupils at his command took each of them hold of an iron handle, whereof there were forty fixed round the edges of the frame; and giving them a sudden turn, the whole disposition of words was entirely changed. He then commanded six and thirty of the lads to read the several lines softly as they appeared upon the frame; and where they found three or four words together that might make part of a sentence, they dictated to the four remaining boys who were scribes. This work was repeated three or four times, and at every turn the engine was so contrived, that the words shifted into new places, as the square bits of wood moved upside down.” (Jonathan Swift, Gulliver’s Travels, A Voyage to Balnibarbi) What astonishing forecast did Swift show in that narrative that, in spite of the underlying incredulity and irony, still clarifies our surprise when faced to what might seem to some of us just an abandonment of all that architects and designers have cherished: creativeness and inventiveness. Yet, we could argue that such a radical shift in paradigm occurred once when master builders left the construction ground and took seat at drafting boards. The whole body of design and construction knowledge was split into what now seem to us just specialties undertaken by more and more isolated professionals. That shift entailed new forms of representation and prediction which now each and all architects take for granted. Also, Cartesian space representation turned out to be the main instrument for professional practice, even if one can argue that it is not more than the unfolding of stone carving techniques that master builders and guilds were so fond of. Enter computing and all its unfolding, i.e. DNA coding, fractal geometry, generative computing, nonlinear dynamics, pattern generation and cellular automata, as a whole new chapter in science, and compare that to conical perspective, descriptive and analytical geometry and calculus, and an image begins to form, delineating a separation between architect and digital designer. In previous works, we have tried approaching the issues regarding architects education in a more consensual way. But it seems now that the whole curricular corpus might be changed as well. The very foundations upon which we prepare future professionals shall change, not only in College, but in High School as well. In this paper, we delve further into the disconnect between current curricula and digital design practices and suggest new disciplinary grounds for a new architectural education.

title A window to the autism: the political role of the difference of an objectile in the homogeneous school
source SIGraDi 2018 [Proceedings of the 22nd Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Brazil, São Carlos 7 - 9 November 2018, pp. 848-853
summary This paper approaches the insertion of an objectile in the homogeneous space of a school, looking to bring flexibility and responsiveness to assist a user with Autism Spectrum Disorder (ASD). The research concerns with photosensitivity, a problem faced by almost 25% of the children with autism (Miller-Horn; Spence; Takeoka, 2011). The study is based on the theories for ASD environments that speak of ‘sensorial perception’ and ‘thinking with imagery’ (Mostafa, 2008), and the coexistence of Sensory Design Theory and Neuro-Typical Method (Pomana, 2015). The result consists of a gadget developed in MIT App Inventor tool and a curtain that interact responsively through an Arduino code, for a new connection between the user and his surroundings.

title Networked mobilities and new sites of mediated interaction
source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 279-286
summary This paper takes point of departure in an understanding of mobility as an important cultural dimension to contemporary life. The movement of objects, signs, and people constitutes material sites of networked relationships. However, as an increasing number of mobility practices are making up our everyday life experiences the movement is much more than a travel from point A to point B. The mobile experiences of the contemporary society are practices that are meaningful and normatively embedded. That is to say, mobility is seen as a cultural phenomenon shaping notions of self and other as well as the relationship to sites and places. Furthermore, an increasing number of such mobile practices are mediated by technologies of tangible and less tangible sorts. The claim in this paper is, that by reflecting upon the meaning of mobility in new mediated interaction spaces we come to test and challenge these established dichotomies as less fruitful ways of thinking. The paper concludes with a research agenda for unfolding a ‘politics of visibility’, engaging with the ambivalences of networked mobilities and mediated projects, and critically challenge of taken for granted interpretations of networked mobilities.

title Reconfigurable Molds as Architecture Machines

summary In The Architecture Machine (1970), Nicholas Negroponte postulates the development of design machines wherein the “design process, considered as evolutionary, can be presented to a machine, also considered as evolutionary, and a mutual training, resilience, and growth can be developed.” The book, dedicated to “the first machine that can appreciate the ges­ture,” argues for developing machines with human like quali­ties. This paper aims to develop an alternative trajectory to the “evolutionary” architecture machine, this time not towards anthropomorphism but responsiveness. The aim on one level is the same: to create machines that appreciate the gesture. However our approach is tied to more modest aims and means that bring current thinking on evolutionary processes and the forming of materials together. The reconfigurable mold (RCM) is an architecture machine that produces parts that can be combined to create more complex organizations. The molds are simple analog computers that employ various continuous scales like volume, weight and heat to develop their unique components. Parametric alterations are made possible by affecting these measures in the process of fabrication. An underlying material that is instrumental in the molds is rub­ber, whose variable elasticity provides unique possibilities for indexing the gesture that remains elusive for industrial pro­cesses.

title Post-Digital Architecture: Towards Integrative Design
source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 149-156
summary In this paper, an alternative vision of integrated design is proposed that is more open, fluid, pliable, and opportunistic in its search of collaborative alliances and agendas. This alternative approach is referred to as integrative design, in which methods, processes, and techniques are discovered, appropriated, adapted, and altered from “elsewhere,” and often “digitally” pursued. The designers who engage design as a broadly integrative endeavor fluidly navigate across different disciplinary territories, and deploy algorithmic thinking, biomimicry, computation, digital fabrication, material exploration, and/or performance analyses to discover and create a process, technique, or a product that is qualitatively new.

title Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 85-102.
summary The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

summary This paper synthesizes several years of research in the field of the theory of architecture and design, and its subsequent undergraduate and graduate teaching. Specifically, it is a work that reflects on how architecture and design should face the three most important paradigmatic phenomena of our present and near future. Paradigms as things we think with, rather than as things we think about (Agamben, 2008), or in other words, it matters what ideas we use to think of other ideas (Strathern, 1992). These phenomena refer to environmental, technological and anthropological aspects, and the strategies to cope with them, involving alternate design thinking and practice in which futurabilities and futurizations depart from the displacement generated by post-utopian visions based on dissidence and subalternity.

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 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.

title Elemental Methods for Integrated Architectures: Experimentation with Design Processes for Cable Net Structures
source International Journal of Architectural Computing vol. 6 - no. 4, 453-475
summary Tension active systems are compelling architectural structures having an intimate connection between structural performance and the arrangement of material. The direct flow of structural forces through the material makes these systems attractive and unique from an aesthetic point of view, but they are a challenge to develop from a design and an engineering perspective. Traditional methods for solving such structural systems rely on both analog modeling techniques and the use of highly advanced engineering software. The complexity and laborious nature of both processes presents a challenge for iterating through design variations. To experiment with the spacemaking capabilities of tension active systems, it is necessary to design methods that can actively couple the digital simulation with the analog methods for building the physical structure. What we propose is a designer-authored process that digitally simulates the behaviors of tension active systems using simple geometric components related to material and structural performance, activated and varied through elemental techniques of scripting. The logics for manufacturing and assembly are to be embedded in the digital generation of form. The intention is to transform what is a highly engineered system into an architectural system where investigation is as much about the determination of space and environment as it is about the arrangement of structure and material.

title Material & Space: Synthesis Strategies based on Evolutionary Developmental Biology
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, 66-71

summary A material system can be defined as a set of self-organized materials, defining a certain spatial arrangement. In architecture, this material arrangement acts as a threshold for space, though space often only appears as a by-product of the material organization. Treating space as a resulting, therefore secondary, independent product minimizes the capacity to generate architecture that is astutely aware of concerns of functionality, environment and energy. An effective arrangement of material can only be determined in relation to the spaces that it defines. When proposing a more critical approach, a material system can be seen as an intimate inter-connection and reciprocal exchange between the material construct and the spatial conditions. It is necessary to re-define material system as a system that coevolves spatial and material configurations through analysis of the resultant whole, in a process of integration and evaluation. ¶ With this understanding of material system comes an expansion in the number of criteria that are simultaneously engaged in the evolution of the design. The material characteristics, as well as the spatial components and forces (external and internal), are pressures onto the arrangement of material and space. ¶ This brings a high degree of complexity to the process. Biological systems are built on methods that resolve complex interactions through sets of simple yet extensible rules. Evolutionary Developmental Biology explains how growth is an interconnected process of external forces registering fitness into a fixed catalogue of morphological genetic tools. Translating the specific framework for biological growth into computational processes, allows the pursuit of an architecture that is fully informed by the interaction of space and material.

title Simulating and assessing prospective scenariosA comparative approach in urban planning
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 The first part of the paper is centred on the phenomena of urban growth, in order to set the rules for a sustainable scenario of urban development. Then we enter the core of the paper that is the comparison of models. For each of the three compared models, we describe its main theoretical characteristics, the chosen parameters, and the obtained results. In section 6, heterogeneity of the produced results is discussed, and we highlight the points of interest and the lacks of the three models. Here we show that results we obtained feed debates about urban growth management. Finally, concluding remarks at the end of the paper address the general topic of the evaluation of the quality of simulation results.

title Noncopyright And The Digital Interface To Support The Autonomous Production Of Dwellings
source International Journal of Architectural Computing vol. 6 - no. 3, pp. 279-297
summary This paper presents the discussions on intellectual property crucial for the research group MOM to develop the system IDA (digital interface for supporting autonomous production of dwellings). It first introduces IDA, its conceptual framework, its database and its interactive interface. Then, it examines the arguments for copyright, identifying them as myths or disguises of other intentions, usually based on perpetuating privileges. From that it discusses the way IDA approaches interaction as a means to break the usual logic of perpetuating privileges in digital systems. This leads to examining some anti-copyright movements concluding that they follow the same logic of register of the copyright. Thus, noncopyright seems to be the best means to protest against the current logic and for conveying information towards autonomy of users in their processes of production of space. It also points to an alternative use of computers in architecture as proposed in IDA, which is not based on representation but on interaction.
