title	Body tailored space: Configuring Space through Embodiment

summary	With this project I propose that embodiment can be more emphasized and better supported in space-design frameworks. This paper presents background on several theories of embodiment since the beginning of the twentieth century to recent developments of the concept in tangible and social computing and anticipate that this reveals pathways for designing new embodiment framework systems for architecture. I suggest that architecture and interactive computing can share a common theoretical foundation in embodied interaction. The main thesis is for designers to use the body as an interface to understand how the interaction between a person and his/her surroundings arises and how our embodiment reveals other rich spatial qualities during the conception phase of design. This paper proposes a conceptual framework for embodied interaction based on the creation of real-time systems in order to instigate a framework for interactive processes that can help designers understand architecture phenomena and the performance of space. I present a design experiment on embodied performance space entitled “Body Tailored Space” where the boundaries of the human body are metaphorically extended into surrounding membranes.

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	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.

title	Artificial networks for spatial analysis
source	International Journal of Architectural Computing vol. 6 - no. 1, pp. 59-78
summary	This paper tests digital representation techniques which can be used by artificial neural networks in a computer-aided design (CAD) environment to analyze and classify architectural spaces. We developed two techniques for encoding volumetric data: vertex representation and feature space representation, as input for artificial neural networks. We tested how two different kinds of artificial neural networks, perceptron networks and self-organizing maps, could recognize given shapes in these representational formats. We have found that a one-layer perceptron can be used to classify shapes even when presented with input vectors composed of real numbers. These spatial representation techniques provide a method for using ANNs for architectural purposes.

title	Design Flow and Ideation
source	International Journal of Architectural Computing vol. 6 - no. 3, pp. 299-316
summary	In the last year, we developed the Hybrid Ideation Space (HIS), an innovative immersive sketching and model-making system that augments analog tools with digital capabilities, for continue and direct reflective conversation with the representation. The system enables designers to sketch and make models all around them in real-time and real scale using a digital tablet (sketches), image capture (physical models) and a spherical projection device (immersion). Teams of industrial design students participated in the study working on the initial stages of the design of a car. This is a comparative study putting side by side the HIS, analog tools and hybrid modeling techniques. We developed the notion of Design Flow to assesses the design ideation process. The students reported being in the state of flow more often in the HIS than with digital or physical modeling.

title	Integration through city space-formUsing space syntax, traffic modelling and geoprocessing tools forevaluating new urban developments
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	New boroughs are continuously being built in Brasilia, Brazil’s Capital City. The paper deals with the performance of such boroughs concerning sociospatial segregation. A comparison is made between two proposals for a new borough to the West of the North Wing of the Pilot Plan, which was originally designed by Lucio Costa. The first proposal was made by a wellknown architectural studio in Brasilia and is beginning to be implemented. The second proposal is an exercise made by undergraduate students from the School of Architecture of the University of Brasilia, under the supervision of one the authors of the paper. The two proposals present very different performances. In the first case, the borough is set apart from the immediate urban surroundings; there is no direct connection between inner roads and the main arteries that surround the site. In the second case, the students have proposed a scheme that connects the interior areas of the borough to the vicinity; we hardly know where the new borough begins vis-à-vis the neighbouring areas. We argue that there are serious traffic implications in the first case, as well as sociological implications. We deal with traffic modelling, space syntax techniques and geoprocessing tools to prove so. Furthermore, we will show how the building types are as well socially inadequate, for they will imply homogeneous social layers among the inhabitants – namely exclusively high-middle class living in the new area.

title	Knowledge Acquisition in Parametric Model Development
source	International Journal of Architectural Computing vol. 6 - no. 4, 435-451
summary	This paper addresses the development of parametric models in contemporary architectural practice. A parametric model can be regarded as a representation of a solution space and in order to structure this, a description of the problem is required. Architectural design tasks are typically ill structured, the goals may not be defined and the means unknown. Moving from an incomplete problem description to a functional parametric model is a difficult task. This paper aims to demonstrate that through a combination of knowledge acquisition and capture a parametric model can develop from an incomplete problem description. This demonstration draws on existing strands of design theory which are then used to outline a theoretical framework. This framework is then used to examine a case study of a live project and practical examples of the described theory in action are given. The practical observations are the result of a case study involving the author as a participant and observer working with HOK Sport to develop a cladding geometry solution for Lansdowne Road Stadium in Dublin.

title	The Impact of Information Technology on Architectural Education in the 21st Century
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 3-6
summary	Architecture is a technology-intensive discipline. It uses technology—both in the process of designing and in its products—to achieve certain functional, cultural, social, economic, and other goals. In turn, technology transforms the discipline. The importance of technology to the discipline and to the practice of architecture has been demonstrated again and again throughout history. In the 21st century, the advent of computer-aided design, computerassisted collaboration, construction automation, “intelligent” buildings, and “virtual” places, promise to have as much of an impact on architectural design processes and products as earlier technological advances have had. Like most other early adoptions of a technology, the first uses of computing in the service of architecture mimicked older methods: electronic drafting, modeling, and rendering. But this rather timid introduction is changing rapidly: new design and evaluation tools allow architects to imagine new building forms, more responsive (and environmentally more responsible) buildings, even radically new types of environments that blend physical with virtual space. Communication and collaboration tools allow architects, engineers, contractors, clients, and others to work much more closely than was possible before, resulting in more complex, more innovative, and more effective designs. Understanding and shaping this transformation are the basis of architectural education in the 21st century.

summary	In this paper, we are interested in developing a smart workplace to assist design activities during design processes from an emotional approach. A key problem in this study is how to design a smart environment, which is able to detect the designer’s emotional state and provides smart mechanism to assist design work. In the preliminary study, a spatial system prototype is developed to illustrate the design ideas of the smart workplace. Some triggered spatial events to describe the capabilities of assisting design activities from an emotional approach is introduced in the study. The framework of ubiquitous computing design in developing the smart workplace is introduced.

title	Smart Space for Office Daily Life: A Situated Life Pattern Approach
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 168-173

summary	Researches in smart space design have been focused on using ubiquitous computing technologies to provide the visions of future lives in physical spaces. However, most researches have less concern for the logical usability in creating smart spaces for the occupants. The study is interested in designing a smart space which is occupant-centric and situated-life-oriented based on ubiquitous computing technologies. A spatial system prototype with smart door, smart wall, and smart table is developed from a situated life pattern approach to support typical office life events. The design problems of integrating ubiquitous computing devices with physical spatial components are explored and discussed.

title	In-situ Analyses of Buildings by means of Smart Devices and Location Based Services
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 635-641
doi	https://doi.org/10.52842/conf.caadria.2008.635
summary	In this research we examined if it might be possible that a client accomplishes an ad-hoc analysis of an existing building with the intention of prospective revitalization. The aim is to give a client who incidentally faces a building the possibility to run an in situ usability simulation. To accomplish this we recommend Location Based Services that can be accessed by common remote sensing devices. These devices should automatically connect to server-based applications, which compare the requirements of the client with the existing building and run remote simulations on concrete further utilization. The newly generated information will then be passed back to the clients’ device. In the paper we address a scenario of a prospective client who visits a city where he hits on an unused building he might be interest in. The client wishes to gain immediate and accurate information if the building is able to meet his demands regarding the space needed for his company. Different techniques investigated, their assets and drawbacks will be described that could accomplish suchlike tasks.

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	Design Rationalization of Irregular Cellular Structures
source	International Journal of Architectural Computing vol. 6 - no. 2, pp. 197-211
summary	Complex geometries found in nature are increasingly used as images and analogies for the creation of form and space in architectural design. To be able to construct the resulting complex building forms, strategies to handle the resulting production requirements are necessary. In the example of a design project for a Japanese noodle bar, a strategy for the realization of an irregular cellular spatial structure is presented. In order to represent its complex geometry, building principles relating to foam are applied to transform and optimize the design, which is based on hexagonal, cellular compartments defining the different interior spaces. The principles are converted into software code and implemented into a digital design toolbox to be used within a 3D-modelling environment. Utilizing the tools within the redesign process made a rationalization of the cellular structures possible without sacrificing the desired visual irregularity. The toolbox also enables the extraction of the cell geometry to support the generation of production documents. The result is the dramatic reduction of production effort to realize the complex cellular structures by keeping a maximum of design flexibility and desired visual appearance.

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	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	A paradigm shift in the world of architecture brought by the recent developments in visualization and communication technology not only offers us drastically different ways to collaborate, but also questions traditional location dependent collaborations. This new technology offers us new possibilities for a more phenomenologically rich mode of creative activity and participation. The goal of the Participatory Design Studio was to allow architecture students in multiple locations to collaborate in real-time by sharing computational resources, geometric datasets, and multimedia content including high-definition video. The technologies involved in this research include the National LambdaRail (layer 3, PacketNet with 1Gb/s connection) and CA*net 4 (Canadian broadband layer 2 with 10gb/s lightpath connectivity) allowing Standard Definition videoconference, utilization of Deep Computing Visualization, Remote Visual Networking (RVN) and Web Service access and control of the APN devices through the dashboard solution that makes integration seamless to the workflow and transparent to the user.

title	Performance-based Design: Current Practices and Research Issues
source	International Journal of Architectural Computing vol. 6 - no. 1, pp. 1-17
summary	In view of current developments in the theory and technology of digital design, potential novel directions for environments that support performance-based design are beginning to emerge. The field of performance-based design is defined through an analysis of current work in the field. Various models of performance-based architectural design are presented and discussed. On the basis of this analysis, key concepts and issues in the application of performance-based design in architecture are defined and certain research directions for the development of new approaches are presented. Finally we propose a new approach termed: Performative Design. Performative Design suggests that in creating simulation environments for performance-based architectural design both generative and evaluative capabilities can be integrated within performance-based simulations. The potential of performance-based simulation as a model of performance-based design is explored through a case study from an experimental digital design studio. Implication of this work on future research directions in the field is explicated.

title	Automated Cost Analysis of Concept Design BIM Models
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. 403-418.
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.

summary	The focus of the research presented in this paper asks how a designer can create a flexible system of physical making which can accommodate multiple programmatic functions within a smooth whole, rather than creating an a priori singular formal object. This adaptable system of construction works through the development of an intelligent CAD model that can be mapped to a flexible manufacturing mechanism, i.e. a reconfigurable mold. This system of manufacturing can be used to cast totally unique solid modules without creating a unique mold for each part by manipulating the topological structure of the system. This approach takes the notion of mass-customization beyond the expensive and unsustainable one-offs that the design world has seen recently, and into a new paradigm of a sustainable, economically viable world of mass-customizable form and space.
