summary As the first design-build-fabricate-assemble experiment at our school, the intent of the studio was to design a framework from which to examine a “lived space” through digital-to-digital processes. Moving from digital models and physical stereo lithographic models to hand-fabrication and digital assembly allowed the students to move from creation to completion. As part of our holistic design process, the studio fabricated almost all components for the project. These elements include the wood flooring, the copper and wood skins, the building’s structural panels, and the two-story light vortex. This single-family, in-fill house is located within an historic downtown neighborhood and is subject to historic district zoning regulations, design guidelines, and Board of Architecture Review approvals. The project is analogous to design challenges presenting themselves in historic districts throughout the United States including the Savannah, Georgia site for the 2005 ACADIA Conference. The scale of the project relates well to the horizontal nature of this context and after a formal, televised review process with the local Board of Architecture Review, the project represents a dynamic, yet sympathetic architectural dialogue with the surrounding buildings. The project develops simultaneously from the exterior and interior resulting in two courtyards that mediate the urban “front door” and the private “terrace.” The students designed these areas through a series of two-dimensional axonometric drawings, three-dimensional physical and digital models, and four-dimensional time-based animations. The building massing separates into two core elements: gabled copper volume and wood screen volume. These elements maintain their conceptual purity by using the same types of modulations on their skins. The copper form with its deep-cut reveals and proportionally placed light scoring patterns reflects the horizontal datum lines of the floor, sill, threshold, and ceiling. In contrast, the wood volume reflects these same lines as applied “shadow screens” which create depths that seamlessly tie together the side, rear, and front facades.The hinge point of the house is the light vortex. Designed in Rhino, translated in Catia, fabricated out of aluminum, and clad in stainless steel, this two-story sculptural element will literally wrap light around its surfaces. Like a sunflower, the light vortex, with its angel hair stainless steel finish, responds to the incremental differentiation of light throughout the day. Photosensitive floor-mounted lights designed to augment the volume of natural light will provide a continuous light rendition on the sculpture. The project, scheduled for completion at the end of the 2005 summer session, is at the time of this submission about 60% complete.

summary Moving from digital models and physical stereo lithographic models to hand-fabrication and digital assembly allowed the students to move from creation to completion. As part of our holistic design process, the studio fabricated almost all components for the project. These elements include the wood flooring and cantilevered staircase, the copper and wood skins, the building’s structural panels, and the two-story light vortex. This project—a single-family, in-fill house located within an historic downtown neighborhood—is subject to historic district zoning regulations, design guidelines, and Board of Architecture Review approvals. The students designed these areas through a series of two-dimensional plans and axonometric drawings, three-dimensional physical and digital models, and four-dimensional time-based animations. The building massing separates into two core elements: a gabled copper volume and a wood screen volume. The hinge point of the house is the light vortex. Photosensitive floor-mounted lights designed to augment the volume of natural light will provide a continuous light rendition on the sculpture.

title A 3D, interactive, multilayered, web-enabled model as a tool for multiple sets of end user groups: A case study and end user analysis

summary This research undertakes a case study involving focus groups of potential end users, to identify how a successful digital tool could be created using new and emerging technologies, to accommodate the multiple needs of these end users. 2005 saw the completion of a research paper, which proposed that a single, 3 dimensional digital model of a city forming a core for many different information systems, is a better approach to the needs of the city than many individual models optimised for each information system. The case for the single 3D model was evaluated through the research, development, delivery and analysis of a prototype 3 Dimensional model of Wellington City, New Zealand, presenting different ‘views’ of information in Wellington: a rendered visualisation in an animated “walkthrough”; the impact of planning constraints on daylight; interactive “plots” of property values. The development and delivery of the prototype model was analysed in regards to how complex, costly and time consuming it may be to exploit one base model for several purposes; and also therefore how beneficial, affordable and potentially successful a single model may be. The prototype model was created to test the idea, and therefore provided conclusions based on a limited feasibility analysis - with four potential information layers modelled and two potential delivery methods tested. The prototype model and user analysis results were presented in a research report that suggested further research and development of a single model could be very beneficial: Positive feedback from potential end users and data providers, and examples of potential data mining opportunities forming the basis of the need for continued research. 2006 sees the research continue as an 18 month research project in conjunction with an industry partner, Terralink International, (http://www.terralink.co.nz/). Terralink International Limited provides GIS and mapping solutions which according to their web site: “enable better business management.” The company maintains a national resource of “imagery, cartography, and spatial databases” and provides consultancy services linking these to company databases through GIS systems. The research investigates the potential for 3 dimensional, interactive, multilayered models to enhance delivery of information to multiple end user groups. The research method uses functional prototypes in end-user focus group workshops. These workshops, consisting of a combination of presentations, hands on interactive examples, group discussions, and individual feedback surveys, aim to establish how a tool might best be developed to communicate to a wide range of end users. The means of delivery whether a stand alone tool or web-based is a key element of the user group workshop assessment process. Note: The submission of the prototype tool (via video or interactive media) would greatly increase the effectiveness of the research presentation. Ability to include such media would be greatly appreciated.

title A Multi-dimensional Exploration of Urban Attributes by Data Mining
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. 333-350.
summary The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970’s in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity’s database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; • Can help in the design process by providing site-specific insight through deeper understanding of urban data. • Can produce results that can assist architects and urban planners at design, policy and strategy levels. • Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

title DecoSketch – Towards Calligraphic Approaches to Interior Design
doi https://doi.org/10.52842/conf.ecaade.2005.665
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 665-670
summary Computer-Aided Design tools have long played an important role in architecture design. However, we need to go beyond direct manipulation to devise new tools that will expedite the interior design and decoration. Indeed, conventional CAD systems, while providing ever increasing functionality, do not provide equal support to the drafting and drawing tasks. This makes even the simplest drawings a complicated endeavor. Draftspeople struggle with different concepts that those learnt from their earlier days in school and have to think long and hard to translate familiar sequences of operations to commands which require navigating a dense jungle of menus. The term calligraphic interfaces was coined by us to designate a large family of applications organized around the drawing paradigm, using a digital stylus and a tablet-and-screen combination as seen most recently in Tablet PCs®. Using these, users can enter drawings in a natural manner, largely evocative of drafting techniques that were perfected for pencil-and-paper media. This paper presents a simple calligraphic interface to explore interior design literally from the ground up. The Decosketch application is a modeling and visualization tool structured around 2 _D architectural plants. Its purpose is to help architects or customers easily creating and navigating through house designs starting from the floorplan and moving to their three-dimensional representation. Moreover, both 2D and 3D representations can be independently edited, providing a natural interface that tries to adhere to well-known representations and idioms used by architects when drafting using pencil and paper.

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 Structured Reflection as a Means to Deepen Understanding of CAAD

summary In this paper we outline a strategy of structured reflection to improve reflection by students in a course on the implication of CAAD, design theory, and design methodology. Earlier editions of the course showed that students often did not evolve their learning beyond a checklist level. Reflection is an important mechanism to improve learning from design situations. After a consideration of the main approaches to design reflection, we take up Schön’s notion of reflection and provide support for structured reflection in CAAD education, based on earlier experiences with structured question lists in a civil engineering course. Findings after the first year’s run show a deeper level of reflection on a more elaborate level.

title A Representation Language for a Prototype CAD Tool for Intelligent Rooms
doi https://doi.org/10.52842/conf.acadia.2005.170
source Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 170-183
summary Intelligent rooms are a type of intelligent environment which enhance ordinary activities within the confines of a room by responding to human interaction using pervasive and ubiquitous computing. In the design of intelligent rooms, the specification of how the intelligent room enacts intelligent behavior through computational means is as integral as the geometric description. The self-aware and context-aware capabilities of intelligent rooms extend the requirements for computer-aided design tools beyond 3D modeling of objects. This article presents a Hardware as Agents Description Language for Intelligent Rooms (HADLIR) to model hardware in an intelligent room as “hardware agents” having sensor and/or effector modalities with rules and goals. End-users describe intelligent room hardware as agents based on the HADLIR representation and write agent rules and goals in Jess for each hardware component. This HADLIR agent description and the requisite software sensors/effectors constitute “hardware agents” which are instantiated into a multi-agent society software environment. The society is then bridged to either a virtual environment to prototype the intelligent room or to microelectronic controllers to implement a physical intelligent room. The integration illustrates how the HADLIR representation assists in the design, simulation and implementation of an intelligent room and provides a foundation technology for CAD tools for the creation of intelligent rooms.

title Design Using Evolutionary Optimisation and Associative Geometry
source Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 243-254
summary This paper describes the usage of parametric design and evolutionary optimisation techniques in architect-engineer collaborations. It discusses the apparent challenges in setting up a trans-disciplinary working-platform that cuts across profession-specific boundaries and negotiates between the otherwise distinct work-methodologies through the use of intelligent CAAD applications. Two approaches to architectural form finding have been combined in this research. The first, parametric design, uses a proprietary package as a key element to the organisation and reorganisation of architectural design. By doing so, it is providing it with intrinsic flexibility allowing designers to go beyond form and accommodate performance data for versioning. The second, ESO (Evolutionary Structural Optimisation), is an engineering tool based on the use of finite element analysis (FEA) capable of optimising the formal geometry of an object to obtain minimum volume under even stress-distribution through an iterative design process. In undertaking this research it became apparent that different levels of resolution need to be addressed in the form-finding process in order to investigate the full potential of the interactive use of parametric design and evolutionary optimisation. The case studies reflect this diversity and demonstrate more successes, limitations and future challenges within the transdisciplinary, collaborative effort.

summary Research on contemporary habitation spaces is directly related to the study of the relationship between new media and everyday life. This paper presents ongoing in-depth research which intends to discuss these relationships in different ways on a conceptual basis. A collaborative multi-users interface is being specially designed, supported by different kinds of electronic equipment. Furthermore, the project’s objective is to analyze how these information and communication technologies are to be used, as well as their impact on poor communities. As a hypothesis, our intention is to verify if the access to information will be able to broaden social interactions and improve new services which have been set up, in order to guarantee a better quality of life. Beyond being a conceptual approach, the study intends to present and examine facts obtained from intervening in a poor district in São Paulo city, Brazil. Using an existing public telecenter as an access provider to the internet, individual TV-connected set-top boxes in 220 apartments in a local social housing complex are being installed, enabling users to communicate through a collaborative multiusers digital interface. Adding a virtual instance to a geographically-based community, the aim of the project is to provide new possibilities to improve dialogue and debates, to encourage more income and cultural activities. It also intends to evaluate the effects of the technological mediation of social relationships, both inside and outside the community, as well as within the physical urban space such as in the dwellings. The results of this study will be useful in defining public policies to be implemented by the Sao Paulo Local Government. The work is being sponsored by FAPESP, which is the Sao Paulo State Funding Agencie, but also by public institutions, private partners and universities. Researchers involved belong to complementary fields such as architecture, urbanism, computer sciences, social sciences, psychology and electronic engineering.

summary Cities are becoming more complex in this digital era due to technological changes. Thinking of cities without such technological changes is equivalent to an embryonic state in the morphology of city growth, that is, the growth seems less advanced. So it is appropriate to think of the non digital city digitally. Urban design is one state which establishes the perfect relationship between the street, people and building. The relationship of the people with the building and street is becoming one of the key factors in architecture. It has been observed that the design of a city has been influenced by the pedestrian movement. Many cities prior to the industrial era were largely determined by the social interactions based on walking. Thus the pedestrians play a key role in the formation of the city. They are a very important component in any representation of transport movements. They generally terminate or initiate a chain of linked activities, and if observed carefully, a single pedestrian movement is meant to include various sub journeys from one location to another. In order to organize pedestrians, we need to understand the pedestrian movement system. Though there is a lot of development of urban models in this aspect, it is still in a nascent state in comparison with the digital advancement. Thus much research work is carried out which can be applied to any given environmental setting, and as a result urban designers can respond to the changing socio-cultural technologies.

source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary This paper describes an experimental practice-based research project that considered design process, implementation and construction of a pavilion built to be part of the Performative Space section of the International Biennale of Contemporary Art, Prague 2005. The project was conceptualized as a time-bound performative situation with a parasite-like relationship to its host environment. Its design has emerged through an innovative iterative process that utilized digital simulative and procedural techniques and was formed in response to place-specific behavioral challenges. This paper presents the project as an in-depth case-study of digital methods in design, mass customization and unified methods of production. In particular, it considers the use of Voronoi patterns for production of structural elements providing detail on programming and construction techniques in relationship to design aspirations and practical constraints.

summary The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for envisaging complex geometric forms. The ‘informed design technique’, apart from being highly instrumental in conceptualizing and generating the geometric component constituting architectural form in a parametric manner, is also efficiently utilized for precise computer aided manufacturing and construction of the speculated form. Geometric complexities inherent in contemporary architectural constructs and the time spent in appropriation of such topologies, fueled the ‘informed design’ approach, which caters to issues of timely construction, precision oriented design and production (visual and material) and parametric modeling attuned to budgetary fluctuations. This design-research approach has been tested and deployed by ONL, for conceiving ‘the Acoustic Barrier’ project, Utrecht Leidsche Rijn in the Netherlands and is treated as a generic case for exemplifying the ‘informed design’ technique in this research paper. The design methodology encourages visualizing architectural substantiations from a systems perspective and envisages upon a rule based adaptive systems approach involving extrapolation of contextual dynamics/ground data in terms of logical ‘rules’. These rules/conditionalities form the basis for spawning parametric logistics to be mapped upon geometric counterparts exemplifying the conception. The simulated parametric relations bind dimensional aspects (length, width, height etc.) of the geometric construct in a relational manner, eventually culminating in a 3D spatial envelope. This evolved envelope is subsequently intersected with a ‘parametric spatio-constructive grid’, creating specific intersecting points between the two. The hence extorted ‘point cloud’ configuration serves as a generic information field concerning highly specific coordinates, parameters and values for each individual point/constructive node it embodies. The relations between these points are directly linked with precise displacements of structural profiles and related scaling factors of cladding materials. Parallel to this object oriented modeling approach, a detailed database (soft/information component) is also maintained to administer the relations between the obtained points. To be able to derive constructible structural and cladding components from the point cloud configuration customized Scripts (combination of Lisp and Max scripts) process the point cloud database. The programmed script-routines, iteratively run calculations to generate steel-wireframes, steel lattice-structure and cladding panels along with their dimensions and execution drawing data. Optimization-routines are also programmed to make rectifications and small adjustments in the calculated data. This precise information is further communicated with CNC milling machines to manifest complex sectional profiles formulating the construct hence enabling timely and effective construction of the conceptualized form.

summary Collaborative design activity that involves remote multilateral, multidisciplinary communication has become more commonplace with the electronic means to communicate across any distance in real time. The communication itself can be both an important repository of project information and an important part of the process of conceptualisation and design development. This research has explored the apparent shortcomings inherent in commonly used means of communication and how these impact on the design process. This paper describes research that has taken as a starting point the analysis and observation of actual design communication from the archive of an internationally published collaborative project involving disciplinarily diverse and globally scattered participants. Through the analysis, we have identified characteristics of communication tools or information environments that would address the particular issues found to impede collaboration while fostering those aspects that support it. The findings have been used to inform the design, specification and implementation of collaborative information spaces based on Wiki software.

summary The development of digital fabrication has reintroduced material processes with digital processes. There has been much discussion about the tool and the objects of the tool, but little discussion of the implication of the material process on the digital process. A brief historical review on the development of computer numerical control and the origins of the Bézier curve reveals an instrumental fact: computer numerical controlled tools necessitated advancements in computational surfaces which eventually led to NURBS (Non-Uniform Rational B-Splines) surfaces. In other words, the origins of NURBS surfaces resides in its relation to material processes, rather than many current approaches that develop free form surfaces and then force the tool onto the material without regard to the material properties. From this historical and mathematical review, this project develops toward more intelligent construction methods based on the integration of NURBS differential geometry paired with material qualities and processes. Specifically, a digital technique of developing conceptual NURBS geometry into piecewise surface patches are then flattened based on the material thickness and density. From these flattened patches, a material technique is developed to intelligently remove material to allow the rigid flat material to re-develop into physical surface patches. The goal of this research is to develop digital and material techniques toward intelligent construction based on the correspondence between digitally driven surface and digitally driven material processes. The application of this technique as a rational and flexible system is to support the dynamic response of form and material toward such performative aspects as structure, daylight, ventilation, and thermal properties.

summary Traditionally, the teaching of digital design systems has been focused on the operative learning of software. However, this almost exclusively technical approach has leaded to a partial view of these systems, as well suited platforms to exploration of project’s possibilities. Consequently their relevance as a base for project representation and therefore as a useful instrument for conceptual exploration for design and experimental research of their processes have been undervalued. On the other hand, this restrictive perspective results in an important waste of the teaching possibilities lying in CAD software related with interdisciplinary teamwork. The following academic experience obeys to a new insight of how to teach these tools, based upon problem solving in Design by interdisciplinary students work teams from Architecture and Industrial Design. In this bet, the learning process is flexible, shared and collaborative, according to the requirements of each project, powered by the commitment of facing common goals. [Full paper in Spanish]

title Generative Design Systems for Housing

summary The present paper describes an undergoing research that aims at developing a generative design computer implementation with an outside-in approach, OIDS. The system will allow developing and visualizing context-based housing development designs. This approach will include both natural characteristics of the site and the existing neighboring buildings. It is argued that certain common urban design practices are the result of a simplification due to difficulties in dealing with the irregularities of the natural environment, which often requires the use of time-consuming methods. The computer-based application will provide tools for dealing with such difficulties, allowing designers to describe their own design rules. In an initial phase of the project, a tool that can subdivide irregular land parcels into equally sized areas has been developed. In further stages, other environmental variables will be addressed, such as solar aspect and prevalent wind directions. Eventually, even the designs of interior layouts should result from exterior forces. The resulting generative system is expected to facilitate and encourage the use of a more organic approach to building siting and design, bringing about the important discussion about which should be the main forces in the generation of the built environment.

title A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.

summary If we compare the architectural design process to a black box system, we can assume that we now know quite well both inputs and outputs of the system. Indeed, everything about the early project either feasibility studies, programming, context integration, site analysis (urban, rural or natural), as well as the integration of participants in a collaborative process can all be considered to initiate and sustain the architectural design and ideation process. Similarly, outputs from that process are also, and to some extent, well known and identifiable. We are referring here, among others, to the project representations or even to the concrete building construction and its post-evaluation. But what about the black box itself that produces the ideation. This is the question that attempts to answer the research. Currently, very few research works linger to identify how the human brain accomplishes those tasks; how to identify the cognitive functions that are playing this role; to what extent they operate and complement each other, and among other things, whether there possibly a chain of causality between these functions. Therefore, this study proposes to define a model that reflects the activity of the black box based on the cognitive activity of the human brain. From an extensive literature review, two cognitive functions have been identified and are investigated to account for some of the complex cognitive activity that occurs during a design process, namely the mental workload and mental imagery. These two variables are measured quantitatively in the context of real design task. Essentially, the mental load is measured using a Bakan's test and the mental imagery with eyes tracking. The statistical software G-Power was used to identify the necessary subject number to obtain for significant variance and correlation result analysis. Thus, in the context of an exploratory research, to ensure effective sample of 0.25 and a statistical power of 0.80, 32 participants are needed. All these participants are students from 3rd, 4th or 5th grade in architecture. They are also very familiar with the architectural design process and the design mediums used, i.e., analog model, freehand drawing and CAD software, SketchUp. In three experimental sessions, participants were asked to design three different projects, namely, a bus shelter, a recycling station and a public toilet. These projects were selected and defined for their complexity similarity, taking into account the available time of 22 minutes, using all three mediums of design, and this in a randomly manner to avoid the order effect. To analyze the two cognitive functions (mental load and mental imagery), two instruments are used. Mental imagery is measured using eye movement tracking with monitoring and quantitative analysis of scan paths and the resulting number and duration of participant eye fixations (Johansson et al, 2005). The mental workload is measured using the performance of a modality hearing secondary task inspired by Bakan'sworks (Bakan et al.; 1963). Each of these three experimental sessions, lasting 90 minutes, was composed of two phases: 1. After calibrating the glasses for eye movement, the subject had to exercise freely for 3 minutes while wearing the glasses and headphones (Bakan task) to get use to the wearing hardware. Then, after reading the guidelines and criteria for the design project (± 5 minutes), he had 22 minutes to execute the design task on a drawing table allowing an upright posture. Once the task is completed, the subject had to take the NASA TLX Test, on the assessment of mental load (± 5 minutes) and a written post-experimental questionnaire on his impressions of the experiment (± 10 minutes). 2. After a break of 5-10 minutes, the participant answered a psychometric test, which is different for each session. These tests (± 20 minutes) are administered in the same order to each participant. Thus, in the first experimental session, the subject had to take the psychometric test from Ekstrom et al. (1978), on spatial performance (Factor-Referenced Cognitive Tests Kit). During the second session, the cognitive style is evaluated using Oltman's test (1971). Finally, in the third and final session, participant creativity is evaluated using Delis-Kaplan test (D-KEFS), Delis et al. (2001). Thus, this study will present the first results of quantitative measures to establish and validate the proposed model. Furthermore, the paper will also discuss the relevance of the proposed approach, considering that currently teaching of ideation in ours schools of architecture in North America is essentially done in a holistic manner through the architectural project.

title Architecture and Biological Analogies
doi https://doi.org/10.52842/conf.ecaade.2005.599
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 599-606
summary The study described in this paper evolves within the larger context of a research aimed at inquiring into analogies between architecture and nature, and more specifically between architecture and biology. Biology is a recursive source of architectural inspiration due to the tight relationship between form and function, the natural balance of forces and the corresponding geometric solutions found in living beings. Roughly, one can classify historical analogies between architecture and biology into two main categories. The first tries to mimic biological forms and the second biological processes. The specific goal of the described study is to find how new technologies can redefine and support the process of constructing such analogies. It uses as a case study a tower project designed by the architect Manuel Gausa (ACTAR, Barcelona) called Tornado Tower because of its complex shape inspired in the frozen form of a tornado. Due to the geometric irregularities of the tower, Gausa’s team had difficulties in designing it, especially because solving the structural problems required constant redrawing. This paper describes the first part of the study which primary goal was to conceive a parametric program that encoded the overall shape of the Tornado Tower. The idea was to use the program to simplify the drawing process. This required a mathematical study of spirals and helices which are at the conceptual basis of the external structure and shape of the tower. However, the program encodes not only the shape of Gausa’s tower, but also the shapes of other buildings with conceptual similarities. Such class of shapes is very recurrent in nature with different scales and with different utilities. Therefore, one can argue that the program makes a mathematical connection between a given natural class of shapes and architecture. The second part of the study will be devoted to extending the program with a genetic algorithm with the goal of guiding the generation of solutions taking into account their structural fitness. This way, the analogy with genetic procedures will be emphasized by the study of the evolution of forms and its limits of feasibility. In summary, the bionic shape analogy is made by the generation of mimetic natural forms and a genetic process analogy starts with the parametric treatment of shape based on code manipulations. At the end the program will establish an analogy between architecture and biology both terms of form and process.

title Crisis? What Crisis?
doi https://doi.org/10.52842/conf.ecaade.2005.547
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 547-556
summary The paper describes the current situation concerning career opportunities in the field of architecture in developed western countries. Several aspects that are almost universal mark this situation. Firstly, there are too many architects chasing traditional work in competition with structural (civil) engineers. This is not surprising in consideration of the fact, that the architectural education industry produces far too many new architects for the economy to absorb. In Germany, the number is almost three times too many. Secondly, the needs of the building industry have changed over the past twenty years so that the skills that architects want to offer are not necessarily those that are sought. Lastly, the constant specialisation of work has continued unabated. Architects, as generalists, have idly watched their areas of expertise be usurped from neighbouring fields like civil and structural engineering The reasons for this crisis are manifold. In the schools of architecture, the discussions often deal with form or formal arguments, which, in fact, have little or no relevance to the building industry. This position was tenable so long as the clients were willing to accept formal arguments in order to receive buildings of high quality or current social relevance (i.e. current architectural fashion). With the dual aspects of globalisation and a shift to maintaining building stocks rather than producing new buildings, the tolerance for “architectural” discussions has been reduced even further. Indeed, the monetary pressures overwhelm almost all other aspects, including so-called green issues. What is more, most of the monetary issues are time based. Time represents, perhaps, the largest pressure in any current planning project. The clients expect expedient, accurate and inexpensive solutions. If architects are not able to produce these, the clients will (and do) go elsewhere. The authors argue that there remain serious problems to be solved for architects and the metier in general. Ever cheaper, ever faster and ever encompassing information technologies offer the architectural community a chance to turn recent trends on their head. By using information technologies to their full potential, architects can reassert themselves as the coordinators of building information and processes. Simply put, this means less photorealistic rendering and more databases, which may be unappealing for those architects who have positioned themselves as “designers” and are able to talk long on form, but short on cost or logistics. Nonetheless, the situation is not lost, so long as architects are able to recognise what is desired from the point of view of the client and what is desired from the point of view of the architect. It is not a question of one or the other. Architects must be able to offer innovative design solutions that not only address the fiscal, legal and programmatic constraints, but also push the boundaries at to the position of architecture in the community at large. For educators, it must be made clear that the real potential architects possess is their encompassing knowledge of the building process including their expertise concerning questions of architectural form, function, history and art. Precisely while they are generalists are architects invaluable in a sea of specialists. The biggest hurdle to asserting this in the past has been the control of the vast amounts of information. This is no longer a problem and also no longer an excuse. In the education of architects, it must be made clear that their role dictates sovereignty over architectural information. Architectural Information Management is a necessary skill alongside the more traditional architectural skills. A brief outlook as to how this might come about is detailed in the paper. The authors propose didactic steps to achieve this. Primarily, the education of computer supported planning should not simply end with a series of lectures or seminars, but culminate in integrated Design Studios (which including Design-Build scenarios).
