title Do We Need CAD during Conceptual Design?
source Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 155-164
summary This paper presents the results of experiments to test whether a designer necessarily needs to produce and utilize external representations in the very early phases of conceptual design. Three architects are engaged in two separate design processes, one is the experiment condition where they were not allowed sketch, and the other, the control condition where they were allowed to sketch. In the experiment condition, architects were required to put on a blindfold and think aloud while designing. The results show that in both conditions the design outcomes fit in the given dimensions of the site, accommodate the space requirements and allow an effective use for the clients. Thus, when the participants were blindfolded, they were able to produce designs by using their cognitive resources to create and hold an internal representation of the design rather than by sketching, or using a CAD tool. We finally raise the question: do architects need CAD representations during the conceptual phase of the design activity?

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.

title Dynamic Generative Modelling System for Urban and Regional Design
source Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 259-268
summary This paper introduces a dynamic generative modelling system for urban and regional design. Through dynamic modelling the system evolves in time according to the interactions of the planners, decision-makers and citizens. On the basis of several synchronous and/or asynchronous user interactions, models are dynamically generated at run time. The models are built by defining the data (datasets) and the actions to perform on that data (tasks). The system reads and correlates data at urban and regional scale from various authorities to generate dynamic datasets. Tasks are especially powerful when they integrate generative procedures in a hierarchical structure. This allows us to model urban and regional dynamics through the interaction of tasks at micro- and macro-scale. Tasks can also implement either Cellular Automata or software agents. We examine the system application to a case project: the simulation of micro- and macro-dynamics in an Alpine valley, with specific challenges to fit competitive and sustainable growth in a landscape quality perspective. The simulation in spatial and temporal dimensions of regional data provided us with the elements to study the territorial evolution over the next twenty years. Four strategies gave as many scenarios highlighting the results of specific policies.

title Group design evaluation

summary Architectural visualization refers not only to the bulk of documents produced in the externalization of design representations but also to a major component of design communication and decision-taking. The paper focuses on the use of visualization in group design processes, i.e. processes typically involving the issues of common authorship, multi-actor design and intensive interaction between different aspects. It proposes that effective group design visualization requires hybrid environments that combine digital and analogue media in unobtrusive and efficient support structures. Registration of design information in group visualization refers primarily to two complementary dimensions: the syntagmatic (the sequence of actions that produce an image) and the paradigmatic (the collection of graphic primitives in the image). Recording syntagmatic information (i.e. who drew what and when) is essential for disentangling the usually dense results of group visualization and for distinguishing between actors, aspects and alternatives.

title Architectural space between reality and virtuality: simulation or reality?
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 517-521
summary This study was carried out under the Theory, Epistemology, and Philosophy principles, and is part of the PAAVI Project: The Architectural Design Process in Interactive Virtual Environments. The study presents part of the theory reference landmark that furnishes support in methodology and process approaches to the empirical research groundwork. The study also addresses the dimensions of architectural space and its representation in cyberspace. Comparisons are made between: static space/dynamic space – mathematical laws/architectural principles – interaction during the infographic process and formal manipulation of software – shape/form/function/space/void – distances/effects/rendering. The basic hypothesis is that the decisions made while solving architectural problems demand in-depth thought and ponderation. This is necessary in the light of the project theory, using the computer tools, electronic media, and concepts that structure different software. These software operations interfere in and interact with conception, appropriation, use and the esthetics of space and architectural form. [Full paper in Portuguese]

summary The development of computer programs has brought about a new trend for architects and designers. Topology, splines, nurbs and the use of sophisticated computer programs, which were formerly possible only to be executed on powerful computers, have triggered an interest in architects. Ten years ago, computers started to replace traditional drawing tools. Nowadays it is possible to develop the whole architectural process in three dimensions (project and manufacturing), reaching certain proposals that otherwise would be impossible or very tedious and time-consuming to carry out. Information technology proposes a new architectonic language, already experimented in a virtual way, but one that can be made real by means of the computer numeric control. [Full paper in Spanish]

title Sensitive Voxel - A reactive tangible surface
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. 525-538.
summary Haptic and tactile sensations, the active or passive exploration of our built surroundings through our sense of touch, give us a direct feeling and detailed information of space, a sense of architecture (Pallasmaa 2005). This paper presents the prototype of a reactive surface system, which focuses its output on the sense of touch. It explains how touch sensations influence the perception of architecture and discusses potential applications that might arise from such systems in the future. A growing number of projects demonstrate the strong impact of interaction design on the human senses and perception. They offer new ways of sensing and experiencing architectural space. But the majority of these interaction concepts focus on visual and auditory output-effects. The sense of touch is typically used as an input generator, but neglected as as a potential receiver of stimuli. With all the possibilities of sensors and micro-devices available nowadays, there is no longer a technical reason for this. It is possible to explore a much wider range of sense responding projects, to broaden the horizon of sensitive interaction concepts (Bullivant 2006). What if the surfaces of our surroundings can actively change the way it feels to touch them? What if things like walls and furniture get the ability to interactively respond to our touch? What new dimensions of communication and esthetic experience will open up when we conceive of tangibility in this bi-directional way? This paper presents a prototype system aimed at exploring these very questions. The prototype consists of a grid of tangible embedded cells, each one combining three kinds of actuators to produce divergent touch stimuli. All cells can be individually controlled from an interactive computer program. By providing a layering of different combinations and impulse intensities, the grid structure enables altering patterns of actuation. Thus it can be employed to explore a sort of individual touch aesthetic, for which - in order to differentiate it from established types of aesthetic experiences - we have created the term 'Euhaptics' (from the Greek ευ = good and άπτω = touch, finger). The possibility to mix a wide range of actuators leads to blending options of touch stimuli. The sense of touch has an expanded perception- spectrum, which can be exploited by this technically embedded superposition. The juxtaposed arrangement of identical multilayered cell-units offers blending and pattern effects of different touch-stimuli. It reveals an augmented form of interaction with surfaces and interactive material structures. The combination of impulses does not need to be fixed a priori; it can be adjusted during the process of use. Thus the sensation of touch can be made personally unique in its qualities. The application on architectural shapes and surfaces allows the user to feel the sensations in a holistic manner – potentially on the entire body. Hence the various dimensions of touch phenomena on the skin can be explored through empirical investigations by the prototype construction. The prototype system presented in the paper is limited in size and resolution, but its functionality suggests various directions of further development. In architectural applications, this new form of overlay may lead to create augmented environments that let inhabitants experience multimodal touch sensations. By interactively controlling the sensual patterns, such environments could get a unique “touch” for every person that inhabit them. But there may be further applications that go beyond the interactive configuration of comfort, possibly opening up new forms of communication for handicapped people or applications in medical and therapeutic fields (Grunwald 2001). The well-known influence of touch- sensations on human psychological processes and moreover their bodily implications suggest that there is a wide scope of beneficial utilisations yet to be investigated.

summary We present the results from the evaluation of the use of KeySet in the architectural BSc curriculum at Delft University of Technology. KeySet is a metadata system that provides data with a unique key consisting of a combination of keywords according to four dimensions. These dimensions constitute the qualities that data possess at different levels. In KeySet, assigning keywords to data is considered a form of claiming these qualities that the data possess.

summary There is growing consensus among architectural critics and educators that there exists an increasing divide between the worlds of architectural education and practice. New social and cultural norms, new materials, and current global concerns, like sustainability, have largely influenced the need for an improved balance/integration between design theory and practice. This places schools of architecture around the world under pressure to provide their graduates with the requisite skills that support responsible design characterized by good design thinking strategies. The Caribbean School of Architecture, in addition to being affected by this predicament, has other pressures on its educational offerings. The region’s lack of resources and particular social issues mandates that graduates of the school adopt a responsible attitude towards design in the region. A positive attitude to such issues as sustainability, energy conservation and community will only come about through an effective transmission of particular architectural knowledge that is relevant to the region. The challenge (globally and in the Caribbean), therefore, is the provision of an innovative and effective way of supporting the student master dialogue in studio, facilitating the transfer of “practical, appropriate knowledge” needed by students to create safe, purposeful and responsible architecture. This paper exists within the research paradigm of providing digital teaching tools to beginning students of architecture. This digital research paradigm seeks to move digital technology (the computer) beyond functioning as an instrumental tool (in visualization, representation and fabrication) to becoming a “Socratic machine” that provides an appropriate environment for design learning. Research funds have been allocated to the author to research and develop the information component of the tool with special reference to the Caribbean. The paper will report on the results of prior investigations, describe the reaction and appreciation of the students and conclude with lessons learnt for the further development of the teaching tool.

title DecoSketch – Towards Calligraphic Approaches to Interior Design

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.

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.

summary Space designers usually look for information on site before proceeding design. They image any possibilities of design, while they are on site. Restricted to traditional design media, if they want to develop their ideas further, they have to go back to desks. This kind of design process can capture only part of information of the site. Why not do some developments directly when designers are on the site? That is the starting point of this paper. The whole situation of site is very complicated, so it is very difficult discussing all the possibilities. In order to understand how to design on site, reducing the variations is needed. Tsai and Chang (2005) proposed a prototype about design on site, which focuses on land forming. So I chose interior as the site to reduce the variation and have more controllable factors. Still there are many factors effecting design on site, scale is very unique and very important factor of them. Beginners are difficult to really feel how long it is on the plan drawing, and even most advanced VR equipment still can’t fully present the rich information on the site. To experience the site though body, the main idea is how to propose a portable device that can support space designer to do design on site directly, with intuitional body movement and precise scale, and get feedback immediately.

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 Traditionally, architecture in its design process employs physical matter, requires physical presence and relies on real world environment using conventional methods of 2D depictions such as paper and pen or 3D representations such as physical models and communicates design ideas in verbal or text-based form. The conventional design process, for example an interior design, a residential house, a commercial complex or even urban design projects, follows the same hierarchy of activities. Efforts are made to the satisfaction of both parties to give the ideas of a physical shape through sketches, drafts and models which may take weeks even months. Finally the project gets its final shape in a working drawing, 3D visualisation or model making. This process is time consuming and somewhat redundant. In recent years technology has offered architects a new tool - the virtual environment. Architects use virtual environment increasingly as device of communication and presentation of design intensions. Virtual environment enables users to interact in real-time with design but unfortunately have not been used widely in the process of design development. The aim of this paper is to investigates the relationship between present design process and the emerging technology of virtual reality, establish a relationship between the two and its influence on architecture to form a new translated design process and communication, an interface between architect and client.

summary Topology optimization methods offer an interesting tool for architects and engineers as a rational basis for the choice of a structure’s initial form, particularly as developments in computer software are compatible with this approach. This can be argued from ecology, resource savings, static load design, financial and a number of other pragmatic reasons. But in an artistic/architectural perspective these are not decisive. Analogical design qualities include a tectonic appreciation of the properties of materials, metaphoric interpretation of intention and considerations of context. The paper describes an attempt to unify analytic and analogical approaches in an architectural education setting, using topology optimization software. It uses as examples recent student projects where the architectural design process based on a topology optimization approach has been investigated. The paper describes and presents results obtained by the students during the project. Further, a discussion is delivered concerning the improved understanding of tectonic design obtained by the student during the projects.

title Interactive Inverted Perspective Rendering for Architectural Visualization

summary Inverted perspective is an illusion of depth perception characterized by the inversion of depth cues in the scene. Distant parts of the scene are shown larger and nearer parts shown smaller than they would appear in linear perspective to achieve the illusion. In this paper, we present a method to achieve this illusion in real-time for interactive applications. We also present a 3D modelling environment for conceptual design which makes use of this display method. Apart from the artistic and perceptual applications of inverted perspective rendering, our method is also very useful for creating an active viewport scene for 3D modelling of solid models with boundaries and complex interior structures. Effective and legible visualization of complex conceptual objects with different kind of layered structures is an important topic for design research. Our method also enables the user to easily create non-photorealistic renderings to understand both the interior and exterior structure of a spatial model from a single image.

summary Virtual reality offers considerable promise with regard to facilitating the building process. A good example is the facilitation of communication between architects and building companies, sellers and buyers or between community planners and the general public. It is often thought that in order to utilise the potential of VR in, for example, the above-mentioned contexts, it is necessary to use fully fledged versions of VR, including stereovision and the possibility of controlling the VR show. However, if a model can also be presented on less advanced equipment and still interpreted in a way that is useful to the viewer it will be possible to distribute the model simply and effectively. This would make it easier to create a more democratic urban planning process compared with if specialised equipment needed to be used and special shows needed to be arranged. In this study we compared the experience of two VR models (a large indoor exhibition hall and an outdoor street in Gothenburg, Sweden) when presented with and without stereovision. When the experience was measured using the Semantic Environmental Scale (the SMB scale, developed by Küller, 1975, 1991), questions on the experience of presence and six other questions on the experience of the models, the results only revealed one indication that stereovision made a difference. This indication was the result for the SMB factor Enclosedness. Suggestions are presented for future research in this area.

summary Modest in budget and ephemeral in nature, STOCK SPACE was installed, exhibited, and dismantled over a five-day period at the Toronto National Trade Center as part of an invited exhibition of concept spaces at the 2005 Toronto Interior Design Show. Occupying 450 square feet within an 110,000-square-foot convention center, STOCK SPACE was small, vertical, warm, and quiet, in contrast to the immense horizontality of the mechanically cooled trade floor of nearly 40,000 exhibitors and attendees. STOCK SPACE was an investigation of limits. Material had to fit through doors and on our CNC milling bed. It had to clear staircases, be carried by hand, and be stored compactly within the confines of our fabrication area. STOCK SPACE was an exercise in subtraction. The space was created through the removal of stock material from a conceptually full volume that measured 24’ long x 18’ wide x 12’ tall. High density EPS foam in 4’x 8’ x 16” modules provided a light and machinable medium capable of recording the vestigial marks of fabrication as well as providing adequate dampening and insulation. The resulting assemblage of stacked modules embodied traits of the orthographic grid associated with the length and width of the stock, the topographic contours associated with the depth of the stock and the isoparametric grooves of the resulting surface. The collective composition of these elements was the analytical result of maximum machining curvature.

summary We are engaged in the process of exploiting gestural signs and pedestrian postures for the purpose of utilizing additional possibilities through the creation of a new Wearable Electronic Garment, as medium for inscription. Animated, cyber-performers move, deform, and re-arrange themselves, augmenting the dimensions of expressiveness/meaning during performance. The cognitive approach produced by thinking in/out of these bodies will similarly trigger changes in consciousness, affecting content and virtual story telling. Together we explore the interaction of text/gestures as movement—as in dance, human day- to-day postures, and our capacity to embody and generate meaning. Cyber dancers use gestures in order to cybernetically inscribe them. The composed gestures become the source of intention that relates to itself; its communicating environment becomes a visualization of the self-reflexivity of both the dance and consciousness. The dance is between worlds of humans, cyber-humans, and the source language as transforms into the domain of visible thought.

title Creating Physical Models Using Virtual Reconstructions: Mixed CAM-techniques for a Viennese Synagogue Scale-model
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 108-113
summary In the framework of a preceding SiGraDi-conference the virtual reconstruction work of Viennese Synagogues was elaborated. The focus of this continued research project is laid on historic/reconstructive modeling, which has specific requirements towards the modeling and subsequent production of scale models. In this paper, the prerequisites of 3D-printing and lasercutting technology for model making will be presented. This includes aspects of scale and handling of individual building elements regarding the possibilities and limitations for each specific CAM-technique. Compared to the rendering models, the modeling procedures for scale-model fabrication had to be adjusted. For example, certain dimensions for details and the structural strength of 3D-printed parts have to be taken into account. Due to economical and constructional reasons as well the printing time involved, a scale-model should be created by means of mixed CAM-techniques; building components have to be split up and assigned accordingly.
