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.

title Plan is Dead: to BIM or not to BIM, that is the question
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 Drawing, modeling and the explicit abstraction embedded in the traditions and conventions of visual communication through composition and representation are fundamental to the how, why and what of architectural design. BIM presents simulation as an antiabstract means of visual communication that seeks to displace the discreet representation of plan, section and elevation with the intelligent object model. If plan is dead, the implication is that the value of abstraction is dead or dying as well. How can architectural education prepare students for digital practice with such an assault on the underlying role of abstract representation of formal and spatial constructs that constitute architecture? This paper explores a possible path for engaging digital media in education that explores the gap between design theory and digital practice. The investigation centers on ways of exploring architecture by developing teaching methods that reprioritize ways of seeing, thinking and making spatial design. Digital architectural education has great opportunity and risk in how it comes to terms with reconceptualizing design education as the profession struggles to redefine the media and methods of architectural deliverables in the age of BIM.

summary An isosurface is a three-dimensional representation of a constant value of a field function within a given volume. They are normally used in computer graphics to visualize data in fluid dynamics, medical imaging, geophysics, and meteorology. The advantage of isosurfaces is that they can represent all sorts of topologies. That makes them a perfect tool for modeling, branching, forking, and bifurcating objects with smooth transitions. As they work of a field function, the surface is implicit, the polygonization an approximation. This is a good base for coupling performance with precision. The task was to define a set of handles to change and model an isosurface. It had to happen through the modeling of the field function in a way that is rather intuitive but without giving up the precision one is used to have from standard NURBS/BREP modeling. The paper shows how a modeling framework for isosurfaces is implemented as a plug-in for Bentley Systems Generative Components allowing an intuitive way of exploring design variations. The implementation is illustrated with a proof of concept showing a sketch design.

summary Urban pedestrian studies on navigation have been conducted for developing applications to ease the task of exploring in a virtual environment. As navigation in virtual environments is evidently difficult and as many virtual worlds have been designed to be used by untrained visitors that explore the environment, navigational supports are critically needed. This study is aimed to collect information about the user needs in order to build a model of user preference and produce simulative scenarios that can reveal the navigational patterns related to street design. The study is based on the attention theory for studying people who are socially interacting with street activities and furniture within designated areas. Furthermore, the study attempts to apply agent interface develop a prototype system with space tags. Finally, the system and its applications, and major findings of these applications are reported

title Road hierarchy and speed limits in Brasília/Brazil
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 aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title Land Use Location and Urban Topology - Exploring this relationships' relevance and an approach methodology

summary This work's first aim is to analyse the relationship between urban axes' topological properties and urban land use location. The second aim is to do it in a straightforward reliable way. A bottom-top methodology is proposed and explored. It is commonly accepted that land use searches within the city for a convenient location, concerning their business. Location is influenced by several factors. These factors and their relative importance differ among land uses. Accessibility is usually recognised as an important factor. This work analyses some land uses in the city of Lisbon in relation to the location parameter: topological accessibility. The exploratory work made clearer it worth studying topology's role in the location of urban land use. Although short on land use types, its wide spectrum in relation to service level confirms both urban topology as an important location parameter and the proposed method as promising.

title Self-Organizing Map and Axial Spatial Arrangement: Topological Mapping of Alternative Designs
doi https://doi.org/10.52842/conf.acadia.2006.342
source Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 342-355
summary This research attempts to formulate a computational framework for exploring spatial arrangements in the early phases of design. In the physical world, this could be compared to exploring spatial arrangements using cardboard cut-outs or simply a grid of spaces on paper. This research demonstrates the framework by means of a generative design system that introduces axial order in a plan parti made up of discrete 3D objects. The tool is designed to organize the 3D objects along an Axis specified by the user and also rearrange them following user-defined mathematical expressions. The numerical parameters (the dimensions and physical properties of the individual objects) are linked through the mathematical expressions to vary the spatial arrangement of objects. Implementation of the tool involves the Self Organizing Maps (SOMs) as the Graphical User Interface (GUI) in generative systems. This allows the user to select and dynamically view spatial arrangements that have been organized on a map based on their similarity. The application is implemented, tested, and its results are demonstrated using buildings designed by Louis I. Kahn, Frank Lloyd Wright and Mies van der Rohe.

summary FFR investigates the self-organization of plaster and elastic fabric to produce evocative visual and acoustic effects. Inspired by the work of the Spanish architect Miguel Fisac and his experiments with flexible concrete formwork in the 1960-70s, FFR continues this line of research by exploring aspects of pattern generation and recognition in relation to self-organized form. In line with the theme of the current exhibition, Digital Exchange, the work can be understood as a dialog between physical and digital computation. The form is a result of a negotiation between the digital manipulation of images and the physical deformations of materials under stress. Both digital and physical processes play an equal role in the final form of the plaster tiles.Reflecting on Miguel Fisac’s flexible concrete formwork, there was a desire to investigate the potential for more differentiated patterns while still using the same basic fabrication technique. This was accomplished through the use of a custom-designed script in Rhino that analyzes a given image and translates it into a field of points. These points establish areas of constraint in the elastic membrane of the mould. Through numerous physical tests, the minimum and maximum distances between constraint points was determined and these were entered into the script as limits for the point creation. If the points are too close, large wholes with very thin and weak plaster form whereas if the points are too far apart the amount of elastic deformation is so great that the weight of the plaster can cause failures to occur in the fabric mould. One of the most important aspects of the project is its resonance with the body and our natural attraction and repulsion for certain forms. Through exploring the natural self-organization of material under stress, FFR unintentionally reminds us of our own flesh. The plaster tiles resonate with our own body’s material as it sags, expands, and wrinkles in relationship with gravity, structure, and time.

summary The building materials that help designers or architects achieve their goal of defining and enclosing space are usually concrete, steel, glass or wood. For these materials designers have both empirical data gained from experience and at times complex calculation methods enabling them to use them in their designs in a tangible, reckonable and, consequently, almost risk-free manner. It seems obvious that creating a design with well-known building materials will lead to more or less predictable outcomes. This is a good reason for investigating a design process dealing with air-filled building-elements. Architectural structures look completely different when one employs a “building material” which has not been subjected to either detailed investigations or sophisticated calculations. The “Smart_Air” Design Studio was devised to take a closer look at the unusual building material “air,” which we have only just begun to explore, and to make it the centre of a focused design exercise. The objective was to use “air” or, rather, pneumatic technologies, to arrive at structurally sound solutions for enclosing space, which could be considered a “roof” in the widest sense of the term.

summary This article communicates results of an experimental pedagogical strategy aiming at both, introducing and taking advantage of new technologies in an architectural design studio. One of the reasons for the notorious unfriendliness of CAD software to the design process comes from the attempt to imitate traditional pen and paper design on the computer. While the whole process could be completely different when performed in a digital environment offering powerful form generation and knowledge modelling possibilities. the proposed teaching method is based on the following principles: (1) emphasis on new methods of designing made possible by the use of computer; (2) communicating the design process, and not only the final result; (3) exploring parametric design for generation of different formal expressions of a design concept; (4) using visual programming to create inter-object relations, etc. A comparison of this experimental approach to other approaches used in design studios (digital or traditional), proves that the architectural results obtained are largely related to the chosen medium and the tools of work. In our opinion, this teaching approach proves to be promising for introducing considerable qualitative changes in the architectural profession, and this way in our built environment as well.

summary Most analytical pedestrian behavior researches use utility-maximizing models and have paid less attention to models based on alternative behavioral theories such as bounded rationality. Consequently, there is a lack of deeper explorations into the decision processes of pedestrians. This lack of such alternative models may also be the result of inappropriate methods to estimate such models. For this reason, the paper first introduces a modeling platform GEPAT which has the ability to estimate parallel functions using a multi-gene-sectional chromosome structure and to facilitate building models using processors emulating simple decision mechanisms. The going-home decision of pedestrians in Wang Fujing Street is taken as an example to illustrate the use of GEPAT. The most important conclusion from a comparison of the MNL, hard cut-off, soft cut-off and hybrid model is that the satisficing heuristic fits better to the problem structure, at least in this case, than the utility-maximizing rule does. This example also shows the flexibility of GEPAT as a modeling toolbox and the power of estimating complex models.

summary Folding is not only a design operation of shaping but also a philosophy theory from Deleuze (Deleuze 1988) which was adopted by architecture. Basically, folding constitutes to forming and topology, which often delivered a mathematical and philosophical expression in generating 3D architectural form. For instance, the work of Eisenman (Eisenman 2003), Libeskind and Lynn (Lynn 1998), they use folding as inspiration to explore the textural folding and bifurcation meaning in the process of form-making. While exploring the meaning of folding, their ideas are expressed by the form using computational tools. Therefore, if a suitable or inspirable tool like our Folding Space (FoS) could be available, such action –fold can be expressed further in the form exploration process.

summary Today's industrials are facing numerous product development challenges and pressures as a result of an increasingly competitive market. It creates an enormous need for a constantly growing supply of new ideas and solutions. The computer support used by designers still lacks the ability to use experiential knowledge in a rational way. Therefore, pursuit of designer is utilizing innovative design methods and problem-solving approaches to systematically simplify design problem, and hence accelerate the design process. This paper proposed to integrate TRIZ method into CBR process and aims at exploring the possibility to use TRIZ method as a complement to enhance performance of CBR in product design. Wall lighting design problem is used as example, and an interactive CBR system is not only built to provide designers a computational tool to efficiently retrieve usefulness design cases but also assist designers systematically in finding creative ideas.

summary This paper discusses the basic principles of a geometric method to aid the design process of residential buildings. It makes part of the initial phases of a research whose aim is to develop a computer system to aid the sketching and evaluation of floor plant design of multi-storied residential buildings. The fundamental idea of the research is the existence of some basic patterns of floor plants that reflect the designer’s mental models in this category of building. The models are regarding the usage of the space such as forms and dimensions, the elements for the circulation and the external skins. During the design process, architects work on each one of these models to generate the sketches of the floor plant layout. Generally, the layout of an apartment in multi-storied buildings depends basically on the internal dynamics of the users without the complex relationship with the neighborhood environment as in the case of houses. In this way, it would be easier to identify, to organize and to associate the mental models of multi-storied buildings on geometric basis, which, in their turns, might be effectively used as inputs for the layout planning of new design. By applying the geometric basis, the architects may reduce the universe of feasible alternatives into a small group of heuristic solutions that can be described by using few simple guidelines. In addition to this, the geometric bases of the existing buildings might be used to build a knowledge-based system to aid the architectural design. The objective of this paper is to show some initial results of the research obtained from a survey and the case studies of form, dimensions and topology of existing buildings. To limit the scope of the discussion, only residential buildings with two to three bedrooms are considered. At first, a survey of plants of residential buildings with two and three bedrooms, in Brazil, is carried out. In the next step, the dimensions, shape, external skin perimeter, circulation system and accessibility are analyzed. Finally, typical topologies of the building are investigated.

summary This paper provides an overview of the requirements for a computational model of a Sensor-Based Aware Environment (SBAE) that integrates sensor technologies with the Building Information Modelling (BIM) in order to sense ambient and physical aspects of the built environment. Wireless sensors sense ambient data of a built environment, process, and communicate these data through an ad-hoc wireless network. The BIM, on the other hand, is based on International Foundation Classes (IFCs) and contains data about the physical infrastructure (i.e. Walls, Windows, doors) and abstract entities (i.e. Spaces, Relationships) and relationships between those entities. Therefore, the proposed computational model could sense real time data that are related to the as-built information model allowing for holistic building state information.

summary In this work in progress report we present the results of a four week design studio with graduate students as part of a broader research project on investigating digital additive fabrication processes and their implications on architectural design.In a simple test arrangement we realized the digital design and additive fabrication of two by three meters brick walls. The use of bricks, being the primary module for construction, and at a relatively coarse resolution, allowed us to concentrate on the design of completely programmed walls encompassing material-dependent parameters. The resulting prototypes depict the great potential of the integration of the design and the fabrication process. Non-standardized solutions can be easily accomplished as the design data is directly used to control the fabrication process. In using an additive digital fabrication process, a novel architectural product of the kind “brick wall” emerged, which could not have been conceived or fabricated manually.

summary The study investigates how religious principles govern the treatment of light/darkness in sacred monument. Specifically, a digitized daylight simulation is used in the analysis of Brihadeshvara Hindu Temple, built in 1010 AD in Tanjore, Tamilnadu, India. This sacred monument, listed as one of UNESCO's World Heritage Sites, is an intriguing case study since the treatment of the 'holy light' in the temple is the treatment of the 'holy darkness'.In spite of the importance given to sun in ancient Hindu scriptures, natural light was used very sparsely in Hindu temples. According to Hindu religious belief, when a worshipper is in the presence of the divine, there should be nothing to distract his/her senses (including vision). Therefore, the innermost sanctum is shrouded in total darkness and the progression into the temple is a ritual movement where the devotee goes through the dynamic experience of the darkening spaces of the temple before reaching the dark sacred chamber (see Fig.1). The dictation of the Hindu faith to create this spiritual procession toward the 'holy darkness' is examined in the historic Brihadeshvara Temple by using Lightscape -- computerized lighting simulation software. To run the program, a 3-D CAD surface model of the temple was created and imported into Lightscape. Then the model was assigned materials and its openings and lighting systems were defined. The simulations were run on four interior horizontal (floor) and vertical (walls) surfaces, along four spaces of the procession in the temple. The simulation targeted three time frames: sunrise, sunset and at high noon on March 21st (the equinox). The location of Tanjore, India was used for light conditions. The Lightscape simulations used the process of radiosity to generate single frame daylight renderings along with light analysis of each surface. A lighting animation was then produced in Quick Time.The results of this analysis demonstrate that the average illumination values for specific surfaces of the temple along the procession sequence correspond to the schematic expectation depicted in Figure 1, i.e., a progressively decreased luminance towards the dark innermost chamber. Furthermore, the simulated values were compared to the Illuminating Engineering Society (IES) standards, which recommend ranges of luminance for specific visual tasks and areas. The comparisons showed that the average luminance in the temple, from the illuminated entrance in the east to the darker chamber in the west, is lower than the IES standards for 'public places with dark surroundings' for 'short temporary visits'. Finally, a morphological analysis of the temple along accepted daylight design guidelines corroborated the previous findings. The multi-method investigation of the relationship of light and darkness, light and objects, and the designated light quality in the Brihadeshvara Temple demonstrates the strong influence of the specific dictum of Hinduism on the light/darkness treatment in the temple. The paper concludes that digitized media such as computerized daylight simulations can examine the significance of light/darkness in sacred monuments as a spiritual experience. This quantitative investigation can augment the qualitative studies in the field of historic sacred architecture.

summary A novel evolutionary system used for the production of design information for digital fabrication is presented. This program generates information for physical construction as architectural models of double-curved walls built from unique masonry units. We present a series of computer programs and physical models as examples of straight and curved walls generated from an evolutionary system built for design. The wall examples here are built of non-uniform, interlocking units. This project is an exploration of evolutionary design tools that construct double-curved structures in CAD for fabrication with a 3D printer.
