title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

summary	With recent developments in communication and information technology there has been increasing research into the role and the impact of computer media in collaborative design. This paper presents a case study that compares two designers collaborating in three different types of virtual environments with face to face (FTF) collaboration. The aim of the study is to identify similarities and differences between remote locations in order to have a better understanding of the impact of different virtual environments on design collaboration. Our results show that the architects had different designing behaviour depending on the type of external representation: they developed more design concepts, and had more design iterations through analysis-synthesis-evaluation while designing FTF and in a remote sketching environment; while the same architects focused on one design concept and making the design when designing in 3D virtual worlds.

title	Revitalization of Existing Buildings through Sustainable Non-Destructive Floor Space Relocation
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 261-268
doi	https://doi.org/10.52842/conf.acadia.2006.261
summary	The revitalization of existing buildings is gaining importance. We are facing a development where, in many cases, there is no need to design new buildings because an increasing number of existing buildings are not used anymore. The most ecological procedure to revitalize these buildings would be through a continued usage and by making few or no alterations to the stock. Thus, the modus operandi could be called a “non-destructive” approach.From the architect’s point of view, non-destructive redesign of existing buildings is time-consuming and complex. The methodology we developed to aid architects in solving such tasks is based on exchanging or swapping utilization of specific rooms in order to reach a design solution. With the aid of mathematical rules, which will be executed by the use of a computer, solutions to floor space relocation problems will be generated. Provided that “design” is in principle a combinatorial problem, i.e., a constraint-based search for an overall optimal solution of a problem, an exemplary method will be described to solve such problems.The design of the model developed is related to problems in logistics (e.g., the loading in trans-shipment centers). The model does not alter geometric proportions or locations of rooms, but solely changes their occupancy such that a new usage could be applied to the building. From our point of view, non-destructive models can play an important role in floor space relocation processes. Our examinations demonstrate that new patterns of utilization could be found through the use of this model.

summary	The impact of collaborative design in virtual environments on the behaviour of designers depends on the nature of the design task and the resources available to the designers. By introducing new technology, we can identify the kinds of positive impacts that should be integrated, and the kinds of negative impacts that should be eliminated, in order to improve the collaborative design environment. We studied designers collaborating in three environments: (1) face-to-face with their current design and communication tools (pen and paper), (2) a shared remote drawing system (Group Board) with synchronous voice and video conference and (3) a 3D virtual world with synchronous voice and video conference. Collaborative design sessions of 5 architect pairs were video recorded. They respectively worked on separate design briefs in the three different design settings. Protocol analysis was used to study and compare collaborative design behaviour.

summary	Augmented Reality (AR) technologies are often perceived as the most impactful method to enhance the communication between the designer and the client during the iterative design process. However, the significance of designing the User Interface (UI) and the User Experience (UX) are often underestimated. To intercede, this research aims to employ new and existing techniques to develop UI's, and comparatively assess "the accuracy and completeness with which specified users can achieve specified goals in particular environments" (Stone, 2005) - a notion this research delineates as 'effectiveness'. Prompted by the work of key scholars, the developed UI's were assessed through the lens of existing UI evaluation techniques, including: Usability Heuristics (Nielsen, 1994) and Visual and Cognitive Heuristics (Zuk and Carpendale, 2006). In partnership with PTW Architects, characteristics such as the rapidity and complexity of interactions, in conjunction with the interface's simplicity and intuitiveness, were extracted from 15 trials underwent by architectural practitioners. The outcomes of this research highlights strategies for the effective development of user interface design for mobile augmented reality applications.

title	FULL 3D STRUCTURAL ZONING OF SPACE: Using a Geometrically Related Reducer and Matrix Coupling
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 161-168
doi	https://doi.org/10.52842/conf.caadria.2006.x.x2d
summary	Structural zoning is the recognition of forms in spatial designs. It can be used by a structural designer to develop a structural system. This paper will start with the presentation of a proof that neither user action nor a two-dimensional approach -two existing approaches of zoning- are able to recognize all possibilities for the application of a structural design to a spatial design. Only full three-dimensional structural zoning is considered to be an appropriate instrument to give useful solutions. Two new concepts will be presented to overcome problems for three-dimensional zoning: (1) Geometrically Related Reducers and (2) Matrix Coupling. These concepts are first defined in a general form and thereafter the definitions are condensed into a practically applicable format. Both concepts are demonstrated when finding rectangular zones in spatial designs up to 44 separate spatial entities. They are programmed procedurally using the C++ computer language and are used for a comparison between structural designers and computer performance.

title	Properly Equip Planners, Instead of Just Manning Equipment - A first step in a user-oriented PSS development approach as support for the integration of land use and transport planning
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 35-50
summary	There is a growing need for planning support in planning practice, especially in land use and transport integration. Recent studies have shown that instruments that provide such are seldom implemented. Building on recommendations of those studies, this paper explores how to develop a planning support system (PSS) for this specific field of planning and shows some preliminary results of the first steps towards such a PSS. An qualitative assessment on the strengths and weaknesses of two recently developed instruments that share this goal; the VPR and the SDS+STE. Due to time constraints, the focus is on the background and framework of the study.

source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 443-451
doi	https://doi.org/10.52842/conf.caadria.2006.x.a6t
summary	The work presented here brings together two core interests that have been developed by the first two authors over recent years. The first is the development of city models for use in a range of applications where different data sets and different levels of detail may be appropriate. The second is the development of low cost systems that can deliver useful tools to help address Computer Aided Architectural Design problems. In addition the involvement of a colleague in Electrical Engineering and Electronics reflects a long standing belief in the benefits of cross-disciplinary and interdisciplinary work between architecture and parallel research fields. The product of the collaboration is a system that can aid in the production of terrain models that, in our case, are particularly important as the base for a city model (Brown et.al, 2005).

title	Inventioneering Architecture: building a doubly curved section through Switzerland
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 544-545
doi	https://doi.org/10.52842/conf.acadia.2006.544
summary	Inventioneering Architecture is an exhibition of the four Swiss architecture schools that has been traveling the world during 2005/06. This doubly curved exhibition platform, resembling an abstract crosscut through Swiss topography, measures 40 by 3 meters. The authors proposed to assemble the hilly platform from 1000 individually curved rafters that were milled out of 40mm medium density fiberboard (MDF). By implementing a continuous digital chain from the definition of the surface geometry in the CAD software Maya to the control of the five-axis CNC-mill that manufactures the parts, production costs could be lowered significantly. The detailing was developed closely after the capabilities of a five-axis router. The platform is divided into 40 mm wide cross sections, each describing the upper surface path of one rafter. The milling tool follows this path and rotates around it at the same time, cutting out a so called “ruled surface” that follows the topography of the platform both along and across the section. In order to meet the budget requirements, the crucial point was to automate the translation of the platform geometry into the geometry of the single parts and finally into the steering code (G-Code) for the computer controlled mill.

summary	Putting a camera close to a scale-model requires deliberately chosen abstractions and refinements in order to communicate the required architectural insights. Depending on what aspects exactly have to be evaluated (e.g. the visualisation of urban space, building blocks, façade structures, urban furniture, traffic, day and night situations, general atmosphere of a place etc.) different choices can be made for level of detail and materialisation of the scale-models. Specific computer controlled tools can be employed to gain high-precision control over model making. In this conference contribution an overview is provided of possibilities from our newly established Computer-Aided- Modelling-lab (CAM-lab). A selection of applications, made by students and researchers, will be presented. Specific choices can make or break the quality of the final presentation. Insight and knowledge of many available techniques, using the right tools and materials, can bring appropriate scenes before the camera. The input from unbiased and freely experimenting students can give happy surprises and new insights. While looking at the broad range of possibilities, inspired by innovative experiments of students in the workshop we work towards a set of best practices. Especially the integration of different digital and traditional techniques remains interesting.

doi	https://doi.org/10.52842/conf.ecaade.2007.351
summary	This paper presents a novel approach for the automatic creation of vegetation scenarios in real or virtual 3D cities in order to simplify the complex design process and time consuming modeling tasks in urban landscape planning. We introduce shape grammars as a practical tool for the rule-based generation of urban open spaces. The automatically generated designs can be used for pre-visualization, master planning, guided design variation and digital content creation in general (e.g. for the entertainment industry). In a first step, we extend the CGA shape grammar by Müller et al. (2006) with urban planning operations. In a second step, we employ the possibilities of shape grammars to encode design patterns (Alexander et al., 1977). Therefore, we propose several examples of design patterns allowing for an intuitive high-level placement of objects common in urban open spaces (e.g. plants). Furthermore, arbitrary interactions between distinct instances of the vegetation and the urban environment can be encoded. With the resulting system, the designer can efficiently vegetate landscape and city parks, alleys, gardens, patios and even single buildings by applying the corresponding shape grammar rules. Our results demonstrate the procedural design process on two practical example scenarios, each one covering a different scale and different contexts of planning. The first example illustrates a derivation of the Garden of Versailles and the second example describes the usage of high-level rule sets to generate a suburbia model.

summary	Which kind of imagination do we need for the future of our planet? In the past 150 years, we have completely transformed our biosphere. Today we have arrived at points of no return in global warming! The temperature of the Arctic Ocean will increase by 3-5°C by mid-century. This will lead to disastrous ocean acidification, sea-level rise, and worst of all the thawing of the permafrost that will release 1 trillion tons of carbon dioxide into the atmosphere. In this paper, we argue that building with biology will be the most important force to transform our planet. Since 2006, Synthetic Biology (SynBio) has surfaced as the fastest-growing technology in human history. SynBio involves emerging techniques that allow us to design, edit, and engineer all kinds of living organisms. In this paper, we elaborate on its potential development in growing infrastructures and its impacts on architectural thinking.

title	Collaborative Architectural Design as a reflective Conversation: an agent facilitated system to support collaborative conceptual design
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	In this paper, definitions of collaborative design are discussed and understood in terms of a designer’s cognitive collaborations to explore his/her experiential memory for remote idea associations. Based on Schon’s reflective practice theory, Valkenburg and Dorst’s (1998) description of collaborative team designing is adopted as a model for a proposed design conversation system. The design conversation system is aimed at triggering the experiential memory of the designer by associating significant ideas from different design domains to provide different perspectives of a design situation. The paper describes a proposed framework for the design conversation system incorporating computational agents in a blackboard architecture environment.

title	A Constraint-Based Building Bulk Design Support
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 278-282
summary	We introduce an architecture practice-oriented implementation strategy of constraint-based methods called BDS (Building Bulk Design Support) to supporting bulk analysis during the architectural programming phase. We examine the optmization problem of site coverage and building massing according to a set of standard planning and zoning regulations, and try a problem solving approach based on the paradigm of constraint satisfaction problems. The case study, which is focused on the paticipatory planning of very low-income dwellings within the Latin American context, serves as testbed for a prototypical application of the adopted methodology. The BDS constitutes a novel approach on computer-aided bulk analysis, regarding this particularly relevant context of application. In the case of participatively planned low-income housing projects, efficiency regarding time and cost of planning directly affects dwellers’ quality of life, whereas elementary programming tasks such as bulk analysis lack appropriate state-of-the-art technological support. Traditional architectural planning methods demand a large domain-specific knowledge base and skillful planners. A planning process, which is mainly driven by the formulation of planning-relevant constraints and sets of solution alternatives, suggests to avoid architects’ traditional procedure of: 1. Create an (yet not necessarily valid) instance of the eventual design solution by directly choosing specific values for its shape parameters. 2. Evaluate its validity by confronting the designed model to a set of applicable constraints, which have to be satisfied. Instead, the constraint-based design methodology poses a search procedure that operates in a space of pertinent constraint sets. A computer-aided interactive search procedure to find more valid design solution alternatives in less time and with less effort is particularly qualified to supply efficient support for participatory planning activities carried out between dwellers and planners. The set of solutions for a building-bulk design problem is constrained by both a large complex system of planning and zoning regulations and the geometry of the eventual design solution itself. Given a considerable amount of such regulations, a regular size geometric constraint satisfaction system proved to be capable of providing a highly efficient, interactive modeling and evaluation tool for the formulation in real time of valid solution alternatives for an ordinary building-bulk design problem. A BDS implementation will constitute one system module of a larger integrated system model called Esther. A BDS tool shall interact with other functional modules, like e.g. the FLS (Floor plan Layout Support), which also uses constraint-based design methods.

title	Automatic Semantic Comparison of STEP Product Models - Application to IFC product models

summary	This paper introduces an original method to compare IFC models and more generally any STEP models. Unlike common 'diff-like' tools which compare textual files by proceeding line against line, our approach compares actual graphs created from STEP-files. Therefore added, removed, and changed objects can be tracked between two versions of the model. Besides, this standalone tool does not need any heavy database to work so it is fully adapted to design methods of construction projects, where actors are free to modify a local version of their project without any dependence on the database. Moreover it is reusable for other industrial fields thanks to its compatibility with any STEP model. This tool is a part from a more global project which tends to improve accessibility and sustainability of IFC therefore it can be used as a support for VR based design tools.

summary	The perception of space, geometry, material and the influence of light is one of the core items of undergraduate courses in architecture. In Bochum we developed and still practise a consequent system of integrating drawing and photography as analytic tools of perception and sketching, descriptive geometry, computer aided design, digital visualisation and animation as synthetic items. The versatile use of digital media in the further studies is of essential significance - especially the synthesis between architectural photography (with all its special features concerning geometrical depicting) and CAD / visualisation / animation. Special emphasis is given to techniques for simulation and immersion such as digital panorama photography, combined with computer-based vr-modelling e.g. vrml as well as using online-cad-modeling and arial photography in processes of citizen participation.

title	Foundations for a Constraint-Based Floor Plan Layout Support in Participatory Planning of Low-Income Housing
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 283-287
summary	We introduce the foundations of a novel approach that deals with constraint-based design methods to supporting participatory planning processes of low-income dwellings. We examine the space allocation problem inside the architectural domain on the basis of graph theory and combinatorics, providing a concise mathematical background for an implementation strategy called FLS (Floor plan Layout Support), which is analyzed here for the first time regarding this particular context of application. The philosophy underlying a design method that is mainly driven by the formulation of distinct constraints suggests to avoid the traditional procedure of first to create a yet not necessarily valid instance of the eventual design solution by directly choosing specific parameter values of its shape, and later on to evaluate its validity by confronting the designed model to a set of applicable constraints. Instead, constraint-based design poses a search procedure that operates in a space of planning-relevant constraint sets. The FLS methodology integrates some few principles of constraint-based automated reasoning with high user interactivity, into a design environment where as much dwellers as planners can collaboratively work in solving spatial organization problems of housing projects. The FLS model of application makes use of a combination of dweller-specified constraints, planning and zoning regulations, and a small library of modular space units. Constraint-based design ! methods are particularly capable of supplying efficient support for the collaborative involvement of dwellers into the architectural programming process of her/his own home. Mainly, because dwellers themselves tend to describe their space need and design intentions as a set of constraints on room quantity, space utilization, circulation system, allocation of available furniture, available budget, construction time, and so forth. The goal is to achieve an integrated tool for finding and modelling topologically valid solutions for floor plan layout alternatives, by combining user-driven interactive procedures with automatic search and generative processes. Thus, several design alternatives can be explored in less time and with less effort than using mainstream procedures of architectural practice. A FLS implementation will constitute one system module of a larger integrated system model called Esther. A FLS tool shall interact with other functional modules, like e.g. the BDS (Building Bulk Design Support), which also uses constraint-based design methods. A preliminary procedural model for the FLS was tested on Chile’s official social housing standards (Chilean Building Code – OGUC. Art. 6.4.1) which are very similar to most Latin American housing programs currently in operation.

title	BIM applications in Design Studio An integrative approach Developing Student Skills with Computer Modeling

summary	This paper proposes a reductionist approach to the integration of software used in professional practice with course activities associated with design studio. This proscriptive strategy emphasizes the use of task-specific software features to support specific aspects of design project activities and learning outcomes. The rationale of this strategy is discussed followed by case studies that review the application of a reductionist approach to building information modeling software in a third year studio and a design foundation course.

title	Forms of Participation in Urban Redevelopment Projects - The differing roles of public and stakeholder contributions to design decision making processes
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 375-390
summary	This paper examines how political commitment to participatory design within the context of a major urban redevelopment project was translated into a strategy and a course of action for achieving effective participation within a demanding project timeframe. The project in question involves a new transport interchange for the city of Auckland (New Zealand), the redevelopment of a number of heritage buildings, and the introduction of new buildings to create a mixed use precinct covering three city blocks. The project, currently being implemented, has involved extensive public consultation and stakeholder participation as it has proceeded through the stages of project visioning, an open public design competition, and the development of the competition winning design. The paper draws a distinction between the contributions of stakeholders versus the public at large to the decision-making process, outlines the different kinds of participatory processes adopted by the local authority (Auckland City Council) to effectively engage and involve these two different groups and the stages in the evolution of the project at which these different contributions were introduced. The model of 'open design' proposed by van Gunsteren and van Loon is used as a basis for explaining the success of multi-stakeholder inputs at a crucial stage in project development. The paper concludes by examining the limits of applicability of the 'open design' model in the context of urban redevelopment projects in which there is broad public interest, and by suggesting a number of design decision support guidelines for the management of participatory processes.
