title	Go with the flow: particle systems for program modeling in high-rise buildings
source	International Journal of Architectural Computing vol. 6 - no. 2, pp. 171-196
summary	This paper revisits the particle flow system, a time-based computational tool, which has received a lot of attention from the early pioneers of digital architecture. The use of particle flow systems in architecture enables designers to materialize what they term as site forces which can later be formalized into a building. The methods offered by various designers for using particle flow systems in architecture have kept the discourse purely formal by focusing on the exterior and neglecting the interior. This paper offers a different way of using and conceptualizing particle flow systems in architecture. Shifting the emphasis from the formal, the paper aims to show the potential of using particle flow systems as a parametric model for exploring the spatial organization of an architectural program. This paper also illustrates the application of the proposed computational model, i.e., the particle flow system, by using a case study - the design of a high-rise building in downtown Tel Aviv, Israel.

summary	Since Hugh Ferris in 1922 started with a series of massing studies the visualization of zoning planning began to be a topic for architects. Setbacks, plot area ratio, maximum building height, and other important attributes must be handled by the architect to fulfill the law, the needs of the clients and his own inspiration. This paper presents the problem of envelope design for high-rise isolated housing buildings, as well as a new Decision Support Systems tool based on the platform of a BIM software, that allows to simulate several options for building envelope according to the parameters required by the city Zoning Planning. These options deliver reliable data and geometry, to be analyzed in real time for the architects, engineers, builders, government and the client in the early stages of the building’s design.

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 study about facades from historical brazilian town using shape grammar
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	Shape grammars have been used in architecture for analysis and synthesis - in the first case, mainly for the characterization of styles and in the later for the generation of novel compositions. The present research proposes the use of shape grammars for establishing guidelines for the requalification of historical areas that have lost their original characteristics due to improper renovations. The use of shape grammars proposed here starts with the definition of a set of rules for characterizing the original style of an area. Based on these rules, the main characteristics of the area are confirmed, such as siting, proportions between walls and openings in the façades, overall dimensions constraints, and so on. Next, the rules of the grammar are transformed, to allow the use of contemporary building materials, as well as the incorporation of contemporary living styles in the new design. Rules must take into account two cases: original buildings that have been inadequately transformed, and buildings that have been completely torn down and will replace been completely replaced by new constructions. Both cases need to be harmonious with the remaining original buildings, however without simply copying the existing style. In both cases, rules have been used to establish the guidelines for the renovations, which resulted in modern urban environments that resemble the original historical sites in terms of spatial relations and proportions. They also create an appropriate environment for the observations of the preserved original buildings, which would otherwise look like aliens in a completely transformed neighborhood. The latter case is very common in most Brazilian cities, especially in the case of São Paulo, where houses from the late 1800´s and early 1900´s are flanked by high rise apartment buildings. In order to develop and test the proposed method, a study will be carried out in a small Brazilian town called Monte Alegre do Sul. The town was chosen because its original urban morphology, developed in the XIXth century, is still relatively well preserved, although part of the original façades have been transformed. The objective of the research is to develop a shape grammar to set guidelines for the re-adaptation of the already renovated façades and reconstruction of other ones in Monte Alegre do Sul.

title	Creation of an Evolutive Conceptual Know-how Framework for Integrative Building Design
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. 435-450.
summary	Low productivity of the building sector today is attributed to the fragmentation of tasks, disciplines and responsibilities, as well as to the resistance to adopt integrative work processes and digital means. The increased complexity of architectural projects and the aroused social consciousness for sustainable environment calls for integrative design collaboration. Thus, there is need for a Conceptual Framework combining work processes, technological means and policy aspects. According to the literature, integrative multidisciplinary design is a strategy resulting in high performance buildings nurturing sustainable way of living (Reed et al. 2009, Krygiel & Nies 2008). Responding to the increased technological complexity of our built environment, as well as to the objective of meeting multiple criteria of quality, both necessitating multidisciplinary collaboration during design, Building Information Modeling (BIM) is seen as a powerful means for fostering quality, augmenting productivity and decreasing loss in construction. Based on recent research, we can propose that a sustainable building can be designed through an integrative design process (IDP) which is best supported by BIM. However, our ongoing research program and consultations with advanced practitioners underscore a number of limitations. For example, a large portion of the interviewed professionals and construction stakeholders do not necessarily see a link between sustainable building, integrative design process and BIM, while in our opinion, their joint use augments the power of each of these approaches taken separately. Thus, there is an urgent necessity for the definition of an IDP-BIM framework, which could guide the building industry to sustainable results and better productivity. This paper defines such a framework, whose theoretical background lays on studies in social learning (activity theory and situated action theories). These theories suggest that learning and knowledge generation occurs mainly within a social process defined as an activity. This corresponds to the context in which the IDP-BIM framework will be used, its final objective being the transformation of building design practices. The proposed IDP-BIM framework is based on previous research and developments. Thus, firstly, IDP process was well formalized in the Roadmap for the Integrated Design Process‚ (Reed et al.) which is widely used as a guideline for collaborative integrative design by innovating practices in USA and Canada. Secondly, the National Building Information Modeling Standard (NBIMS) of the USA is putting an enormous effort in creating a BIM standard, Succar (2008) recently proposed a conceptual framework for BIM, but BIM ontology is still under development (Gursel et al 2009). Thirdly, an iterative design process bound to gating reviews (inspired from software development processes) was found to be successful in the context of multidisciplinary design studios (reported in our previous papers). The feedback from this study allowed for modifications and adjustments included in the present proposal. The gating process assures the good quality of the project and its compliance to the client's requirements. The challenge of this research is to map the above mentioned approaches, processes and technologies into the design process, thus creating an integrated framework supporting and nurturing sustainable design. The IDP-BIM framework can be represented by a multidimensional matrix linked to a semantic network knowledge database: - the axes of the matrix being the project timeline, the design process actors and building stakeholders (architect, engineers, client, contractor, environmental biologist, etc.), or different aspects of building performance (environmental, functional, social, interior environment quality, cost, etc.); and - the knowledge database providing multiple layers of semantic support in terms of process, domain knowledge, technology and workflow at a given moment of the project and for a given actor or building aspect. The IDP-BIM framework is created as an evolutive digital environment for know-how and will have an established protocol for regular updates. The paper will firstly present the state of the art in IDP and BIM. Secondly, it will expose the methodology used for the definition of the Framework, followed by a description of its structure, contents and digital implementation. Then, some scenarios for the use of the Framework will be shown as validation.

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.

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	Hybrid Art > Synthesized Architecture
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This paper investigates possible intersections between some contemporary artistic modalities and architectural practice. At first, it describes and discusses different uses of art in architectural history. Through the analyzes of Le Corbusier’s artistic and architectural practices, it observes the limits of looking at art as only ‘inspiration’ for architectural form and points to the necessity of surpassing this formal approach. More than bringing pictorial ‘inspiration’, art, as a experimental field, can change our architectural procedures and approaches - a much richer and powerful addition to the development of architecture. It discusses then, the confluence of architecture, information and communication technologies. Very commonly present in our contemporary life, not only on the making of architecture – computer drawings and modeling of extravagant buildings – nor in ‘automated rooms’ of the millionaire’s houses. Televisions, telephones and computers leave the walls of our houses “with as many holes as a Swiss cheese”, as Flusser has pointed. The architecture has historically manipulated the way people interact, but this interaction now has been greatly changed by new technologies. Since is inevitable to think the contemporary world without them, it is extreme urgent that architects start dealing with this whole universe in a creative way. Important changes in architecture occur after professionals start to research and experiment with different artistic medias, not limiting their visions to painting and sculpture. The main hypothesis of this paper is that the experiments with new media art can bring the field of architecture closer to information and communication technologies. This confluence can only take form when architects rise questions about technology based interaction and automation during their creative process, embodying these concepts into the architecture repertoire. An educational experience was conducted in 2007 at UFMG Architecture School, in Brazil, with the intention of this activity was to allow students to research creatively with both information technology and architecture. The students’ goal was to create site-specific interventions on the school building, using physical and digital devices. Finally, the paper contextualizes this experience with the discussion above exposed. Concluding with an exposition of the potentialities of some contemporary art modalities (specially the hybrid ones) in qualifying architectural practices.

title	Balancing Design and Performance in Building Retrofitting: A Case Study Based on Parametric Modeling
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, 214-221
doi	https://doi.org/10.52842/conf.acadia.2008.214
summary	Retrofitting the existing building stock will become one of the key fields of action for architects in the future. Due to the raised awareness of CO2 emissions related to the energy consumption of buildings, architects have to increasingly consider parameters influencing the energy performance of their retrofit designs. This is a complex task especially in the early design stages as multiple dependencies between building form, construction and technical systems influence overall energy performance. The inability to cope with this complexity often leads to simple solutions such as the application of massive insulation on the outside, neglecting aesthetic expression and design flexibility. Digital models storing multidisciplinary building information make it possible to include performance parameters throughout the architectural design process. In addition to the geometric parameters constituting the form, semantic and topological parameters define building element properties and their dependencies. This offers an integrated view of the building. We present a case study utilizing mulit-parametric façade elements within a building information model for an integrated design approach. The case study is based on a retrofit project of a multi-family house with very poor energy performance. Within a design workshop a parametric building model was used for the development of the designs. An integrated analysis tool allowed an immediate performance assessment without importing or exporting building data. The students were able to freely define geometric and performance parameters to develop their design solution. Balancing between formal expression and energy performance lead to integrated design sketches, resulting in surprising solutions for the given design task.

title	Rapid Agent Based Simulation of People Flow forDesign of SpacesAnalysis, Design and Optimisation
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	This paper presents a novel static-dynamic network based people flow simulation model applied to design optimisation of circulation spaces within buildings and urban areas. In the current state of art the majority of existing people flow simulation models are driven by analysis rather than design. This is fine for simpler, evacuation type scenarios where a single or a few analyses runs are sufficient to determine the evacuation time. For more complex scenarios such as crowd circulation with complex multi-directional flow, one is as interested in the sensitivity of various design and stochastic behavioural parameters, so the rapid modelling simulations together with design capability become important. This paper presents a simplified network based people flow model that enables rapid simulations and therefore iterative design optimization of circulation space. The work integrates the techniques of graph-theory based network analysis with an origin-destination matrix model of crowd flow, to provide a rapid, parametric model. The resulting model can be analysed in a static as well as dynamic state. In the static state, the model analyses space based on connectivity of nodes, superimposed with the origin-destination matrix of population to provide valuable information such as footfalls, density maps, as well as quasi-static parameters such as mean flow rates. In the dynamic state, the model allows time-dependent analysis of flow using a detailed agent based simulation that also incorporates dynamic route-choice modelling, agent behaviours and interaction, and stochastic variations. The paper presents the integrated modelling technique and its implementation into simulation software SMART Move.

summary	This paper considers the problem of detailing joints between manual and digital construction by tracking the provocations of KieranTimberlake’s SmartWrap research and the evolution of that knowledge into practical architectural instruments that can be deployed into more traditional construction projects. Over the past several years, KieranTimberlake Associates in Philadelphia has undertaken a path of research focusing on problems of contemporary construction systems and practices. One product of this research was a speculative wall system assembled for a museum exhibit. SmartWrap was to be a digitally prefabricated wall system with embedded technology. ¶ While they have yet to wrap a building with SmartWrap, KieranTimberlake have utilized a number of the construction principles and digital tools tested in the SmartWrap exhibit. One of the most important principles, prefabrication, was explored in a fast-track construction project at the Sidwell Friends School. The compressed schedule drove the design of an enclosure system which incorporated performative elements in similar categories to SmartWrap: insulation, an electrical system, view, daylighting, and a rainscreen. Besides being a prefabricated façade system, the rainscreen detailing became a formal system for organizing many other scales of the project including: site systems, thermal systems, daylighting systems, enclosure, and ornament. At a second project, a similar wood rainscreen strategy was used. However, at the Loblolly House the question of prefabrication and digital modeling was tested far more extensively: thermal systems were embedded into prefabricated floor cartridges, entire program elements – a library, kitchen, and bathroom were proposed as prefabricated systems of self-contained volume and infrastructure which were then inserted into the on-site framework. ; In all three projects the joint between manual-imprecise construction and digital-precise prefabrication became the area of richest invention (Figure 1). SmartWrap may not have yielded flexible, plastic architecture; but its conceptual and practical questions have yielded tangible implications for the design/construction processes and the built product in KieranTimberlake’s practice.

summary	Historically, the city represents not just a collection of buildings, but also the concrete cosmology of the world. The importance of geometry in this context is that one can be assured that one’s understanding of the form of the city will correspond to meaning. It is this reading that is the canonical visualization method of the city form. But contemporary urban designers are confronted by cities with overlapping systems of movement and information that has made the reading of geometry insufficient for an understanding of the city. Our interdisciplinary team of researchers has been studying issues related to urban visualization from the perspectives of urban design and computer visualization. Together, we have published work demonstrating how very large and disparate data sets can be visualized and integrated in unique ways. Building on this existing work that connects the two disciplines, this paper presents a survey of six urban design methodologies that may be useful for visualization. Each approach is described through a brief history, a conceptual overview and a diagrammatic exegesis. The conclusion presents an overview of the complementary natures of the discourses in urban design and computer visualization and a prospectus for application of the identified methodologies to computer urban visualization. We conclude that urban theories can inform urban visualization both as a method of informing generation and run-time simplification of 3D geometric modeling and in managing information visualization overlay issues for the very large, over-lapping data sets.

summary	This paper describes our research on environment-behavior simulation and focuses on the modeling of built environments using Computer-Aided Design (CAD) and Building Information Modeling (BIM). Our environment-behavior simulation addresses the problem of predicting and evaluating the impacts of built environments on their human inhabitants. We present simulation systems comprising an agent-based virtual user model and building models created with CAD and BIM tools. We compare the use of CAD vs. BIM with two case studies for environment-behavior simulation, and describe the essential parts of modeling buildings for the simulation, including geometry modeling—how the building components are shaped, semantic modeling—what the building components are, and pattern modeling—how the building components are used by users. We conclude that a new extensible and pattern-embedded BIM system will be necessary to facilitate environment-behavior simulation.

title	Multi-Directional Interrelationship Approach For Hybrid Interactive Design Tool For High-Rise Building

summary	The role of computers in architectural design is constantly increasing, as may be seen in the efforts to develop generative design tools which are focused on helping create innovative results. Some of these are generated by sets of rules, constraints, theoretical models and algorithms, for which the computer is used as the implementing tool. This research introduces a new approach in hybrid interactive design tools, which are focused on the clustered and hectic urban context in the modern age, meaning that architecture is continuously developing vertically, in high-rise buildings. The main point in this research will be the abandoned gap in connecting the internal functions and external appearance. This is another main point which cannot be ignored in designing high rises, which ideally contain both internal and external perceptive aesthetics. The scope of this research will cover three aspects: Function, Perception, and Proportion. Therefore, the work flow of this design tool will be a multi-directional interrelationship between these three steps: 1) internal function and external form generation by various types of constraints, 2) internal function and external form inspection, and 3) internal function and external form modification by the users.

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.

summary	This work invests on delimitation of a Geometric Modeling study program directed to students at the initial stages of Architecture. It is considered that the studies promote a qualified control of the form based on recognition of parameters which define it, moreover it also allows the enlargement of the students geometric vocabulary, important to the architectural design activities. In this way, the program advances on the appropriation of new concepts which surround the investigations on architectural design processes, such as the concept of shape grammar. Observing analysis and architectural composition practices based on such concept, contents of geometric modeling which are already being used in the context of post-graduation are identified to be transposed to the graduation context, along with the initial teaching practices of architectural design. The results refer to making the didactic material available, these materials have the objective of building references for the development of design practice which explore the reflection about the processes of creation and composition of architectural form in their geometric aspects.

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.

summary	The transition from conventional to sustainable building depends on a number of factors— technological, environmental, economic and social. From a computer-aided design perspective, the first two are perhaps the most significant. We are working on a project with an emphasis on developing tools, to evaluate environmental consequences for design decision-making. Our current thrust is given to reducing energy usage as well as carbon emissions in buildings.

summary	Our contention is that the city is a rich collection of urban micro-ecologies in continuous formation that include information types outside the traditional boundaries of urban design, city planning, and architecture and their native data fields. This paper discusses working with non-standard urban data types of a highly granular nature, and the analytical possibilities and technical issues associated with their aggregation, through a post professional masters level research studio project run in 2008. Opportunities for novel urban analysis arising from this process are discussed in the context of typical urban planning and analysis systems and locative media practices. This research bought to light specific technical and conceptual issues arising from the combination of processes including sources of data, data collection methods, data formatting, aggregating and visualisation. The range and nature of publicly available information and its value in an urban analysis context is also explored, linking collective information sites such as Pachube, to local environmental analysis and sensor webs. These are discussed in this paper, toward determining the possibilities for novel understandings of the city from a user centric, real-time urban perspective.

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?
