summary One of the most important aspects architects need to consider fairly early on is that of energy saving, cost, thermal comfort and the effect on the environment in terms of CO2 emissions. At present, during the early design stage of a building, different options are assessed using simple tools (tables, graphs and software) that contain a large number of assumptions the very nature of which can bias choice or possibly lead to an inappropriate solution. It can be argued that the only way to provide a rational assessment of options is to use calculation methods that represent in detail the physical processes involved; this usually involves the use of dynamic thermal models. Furthermore if this tool is also used during detailed design it would introduce a consistency that is normally absent from the analytical design process. Many designers are of the opinion that, because not all details are known, then such tools are not suitable for application at early stages in the design. This view can be challenged because, even at the concept stage, a great deal is known about a building. This paper aims to show that a general description of a building can be used to generate sufficient data to drive a valid analysis using a detailed thermal model at the early sketch stage of the design process. The paper describes the philosophy, methodology and the interface developed to achieve this aim. The interface guides the user through the input process using a series of screens giving options for keywords used to describe the building; comprehensive default data built into the software are then attached to these keywords. The resulting data file is a building description that is the best possible interpretation of the design intent. This can then be used to assess options and guide towards a final design.

title SGML: a meta-language for shape grammars
source PhD dissertation, Department of Architecture, Massachusetts Institute of Technology, Cambridge, Mass
summary A shape grammar develops a drawing through a series of transformations by repeatedly applying if-then rules. Although the rules can be designed, in principle, to construct any type of drawing, the drawings they construct may not necessarily develop in the manner intended by the designer of the grammar. In this thesis, I introduce a shape grammar meta-language that adds power to grammars based on the shape grammar language. Using the shape grammar meta-language, the author of a grammar can: (1) explicitly determine the sequence in which a set of rules is applied; (2) restrict rule application through a filtering process; and (3) use context to guide the rule matching process, all of which provide a guided design experience for the user of the grammar. Three example grammars demonstrate the effectiveness of the meta-language. The first example is the Bilateral Grid grammar which demonstrates how the meta-language facilitates the development of grammars that offer users multiple design choices. The second grammar is the Hexagon Path grammar which demonstrates how the metalanguage is useful in contexts other than architectural design. The third and most ambitious example is the Durand grammar which embodies the floor plan design process described in Précis of the Lectures of Architecture, written by JNL Durand, an eighteenth century architectural educator. Durand's floor plan design process develops a plan through a series of transformations from grid to axis to parti to wall. The corresponding Durand grammar, which consists of 74 rules and 15 macros organized into eight stages, captures Durand's ideas and fills in gaps in Durand's description of his process. A key contribution of this thesis is the seven descriptors that constitute the meta-language. The descriptors are used in grammar rules: (1) to organize a set of rules for the user to choose from; (2) to group together a series of rules; (3) to filter information in a drawing; (4) to constrain where a rule can apply; and (5) to control how a rule is applied. The end result is a language that allows the author to create grammars that guide users by carefully controlling the design process in the manner intended by the author.

title The use of learning algorithms for real-time immersive data visualization in buildings
source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary Computational Fluid Dynamic (CFD) simulations are used to predict indoor thermal environments and assess their response to specific internal/external conditions. Although computing power has increased exponentially in the past decade, CFD simulations are time consuming and their prediction results cannot be used for real-time immersive visualization in buildings. A method that can bypass the time consuming simulations and generate .acceptable. results will allow such visualization to be constructed. This paper discusses a project that utilizes Artificial Neural Network (ANN) as a learning algorithm to predict post-processed CFD data to ensure rapid data visualization. The technique has been integrated with an immersive Augmented Reality (AR) system to visualize CFD results in buildings. ANN was also evaluated against a linear regression model. Both models were tested and validated with datasets to determine their degree of accuracy. Initial tests, conducted to evaluate the user.s experience of the system, indicated satisfactory results.

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.

title Modularity and Flexibility at the Small Scale: Evolving Continuous Material Variation with Stereolithography
source Fabrication: Examining the Digital Practice of Architecture [Proceedings of the 23rd Annual Conference of the Association for Computer Aided Design in Architecture and the 2004 Conference of the AIA Technology in Architectural Practice Knowledge Community / ISBN 0-9696665-2-7] Cambridge (Ontario) 8-14 November, 2004, 76-87
summary In this paper, we introduce a technique by which the internal material properties of an object can be optimised at a microstructural level (5x10-5m) to counteract the forces that are applied to it. These can then be fabricated using the rapid prototyping method of stere­olithography. The proposed technique is analogous to principles of mass customization and takes advantage of a flexible module to cre­ate complex structures in a manner that is computationally efficient and effective. The process is two-staged, in which a genetic algorithm evolves the topology of the microstructure and a second algorithm incorporating Finite Element Analysis then optimises the geometry. The examples shown are designed specifically for the fabrication tech­nique, but the method and general principles are applicable to struc­tural problems at any scale.

summary This paper is original research that demonstrates new design possibilities for evaluation in the schematic phase of design through the use rapid prototyping as a tool of representation verses 2D drawing. These program shapes are created from CAD files using a threedimensional printing and laser cutting CAM tools. This way of working is in response to two dimensional plan representation and evaluation (Mitchell 1976). This research combines the best of the visual aspects of plan representation and the formal representation of solid block modeling. The models in this paper demonstrate the building’s physical scale of spaces, building use and overall form. Resulting models will demonstrate a new way of designing in CAD one that combined physical and visual ways or representation.

summary We investigate the creation and reinterpretation of an architectural design process using a variety of digital and physical media. We study how tools for design influence perception, comprehension and creation of spatial volumes within both Virtual Environments (VE) and physical realms. We explain how designers translate spatial volumes and communicate architectural design ideas by using VE and conventional models. In a series of reinterpretation of architectural meanings we examine the translation of threedimensional design from virtual to tangible depictions and vice versa. We conduct a design-studio in order to explore issues of quality, understanding, communication and building of architectural compositions. VE can be an environment for design distinguishable and facilitating reality. We test this statement by interchanging both realms to that extent that the boundaries of each one are nearly dismantled. Virtuality and reality are both used in alternative formand design-finding exercises in order to gain an overall conclusive design.

title The Synthetic Sublime

summary The distinction between the artificial and the natural has been increasingly challenged as a result of advances in genetics, microbiol¬ogy, and robotics. Beginning with the molecular assemblage of organic systems into complex micro-surfaces and structures, and expanding into the realm of the macro landscape, our understanding of the term Synthetic must be revised. What is the relationship between the component (or part) and the whole, when confronted with the Synthetic? Digitally mediated fabrication technologies, combined with a renewed interest in topology and (bio)logical form, serve to challenge our preconceived notions of space and form. This inquiry will attempt to explore the relationship between traditional assemblies produced by hand, and the production of complex forms through digital rapid prototyping. The impact of D'Arcy Thompson's On Growth and Form will be considered both as a historical juncture and a contemporary source of knowledge for the exploration of new assemblages inspired by topology and biology. In particular, the organic micro-surfaces depicted in France Bourély's Hidden Beauty will be explored, in comparison with the mathematical development of organic forms inspired by Periodic Minimal Surfaces. The analysis of emerging forms and assemblages based on the notion of the Synthetic will be compared with the Organic, and considered within the context of twentieth century art and sculpture. An attempt will be made to establish new modes of inquiry for combining digital and physical explorations of space and form, influenced by advances in micro-scale structures, complex surfaces, and the history of organic form in art.

summary Design of assemblies will become an area of study when using rapid prototyping devices in the architectural design process becomes standard practice. This paper is a presentation of a design process study focused on understanding a method of working with rapid prototyping devices in a creative design process. This paper has an emphasis is on the creation of physically large models. These models are built from many layers of detail and are too large to print on a conventional 3D building device (3D printer). In response to this is a proposal to design assemblies as a means to create models of parts manufactured with rapid prototyping devices. Design for Assembly (DFA) becomes an exclusive process within this method of model making. Designing assemblies as part of a creative design enterprise offers greater knowledge of the building's construct at an early stage of the process. As an example, there are three physical models built from 3D CAD descriptions for this study. These models are manufactured from various rapid prototyping devices and differing processes of assembly. They are evidence of DFA as a necessary process in architectural design when using rapid prototyping devices.

summary The Academic Upgrade Program (.Capacitación Docente.) is been developed in the contexto of a MECESUP project (government funding assignments for education) at the FAU of Universidad de Chile. This program is about upgrading knowledge and user capabilities in Information and Communication Technologies (IT) of our academic team, in order to improve our pedagogical model, and to include these IT into the learning-teaching process for Architecture, Design and Geography. Considering that new technologies are part of the contemporary professional development and they are already included in high school in Chile, they should be part of the university academic environment as well, as an important tool and a link between generations, careers, and stages of education. Estimulating a cultural transformation process in the academic team, promoting transversal network thinking and to generate a base of knowledge in digital culture are our main objectives. This is our contribution to a new academic model, which we need in deed.

title Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools

summary Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call “business views”. We propose a 4 steps-method to compose business views. The first step identifies the users’ business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user’s interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary In the previous study, we had applied the data mining techniques and ontology methodology to develop a keyword-based schema to extract and represent the implicit information within a case library, Case Base for Architecture (CBA). To improve the ability of our keyword-based schema on extracting and representing design knowledge within cases, we proceeded some experiments to understand the design’s mental behaviors in extracting knowledge from cases. Through protocol analysis, we attempted to establish a knowledge discovery model of extracting design knowledge from cases, and to propose methods to apply this model to improve our keyword-based schema. Through collecting adjective keywords to restructure our design dictionary, we attempt to make our system more sensitive to design knowledge, and more sensitive to user’s intensions by extending the ontology of our keyword list.

summary The social and economic context of architectural co-operative projects does not support the experimentations with dedicated tools. Therefore, we chose to achieve functional validations and operations of communication about tools usefulness with the use of scenarios. The scenario techniques are usually used in computer science to capture user’s needs and to validate software specifications. After having analyzed the different contexts of scenario usage in computer science, we characterize the specific context of the use of tools in cooperative activities. Then, we report some experiences of functional validation, of tool demonstration and of usefulness validation based on the use of scenarios. We explain in each experience the objectives and their implication in the scenario definition.

title A COMPARISON OF 3D VISUALIZATION TECHNOLOGIES AND THEIR USER INTERFACES WITH DATA SPECIFIC TO ARCHITECTURE
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 99-111
summary Contemporary advanced virtual reality systems use different stereoscopic 3D visualization technologies. In this study, VR systems from one projection wall up to VR systems with six projection walls have been evaluated. Besides the optical properties tested with architectural 3D models, the user interfaces have been analyzed with reference to exact and intuitive control abilities. Additionally, the workflow of an early architectural design process with CAAD generated 3D models and VR visualization techniques was analyzed. It turns out that current VR systems exhibit shortcomings in visual and spatial representations, as well as tools for an early design process.

title Visual Simulation as a Tool for Planning Education - Computer Aided Participation Support
source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 500-507
summary Contemporary computer techniques offer many new opportunities to engage citizens into the planning process. There are new possibilities of interaction, introducing an observer into the “game”. The research project presented in the paper assumes the use of a visual 3D language which consists of a series of schematic types of buildings. They form a language which is easy to understand both by professionals and by laymen. Understanding is the very first step towards getting convinced by the ideas presented. The next step is interaction - the user’s action induces the response of the system. The solution proposed by the user meets an evaluation from the part of the system which evokes the user’s interest - in the case presented here the evaluation introduces the simulation of future state of the site. The problem posed is to find out the best way to convince people that some places are less or more suitable for settlement, depending on the media present there, distance from the urban areas and the environment protection. The attempt to create a tool which could be helpful in an educational process is described in the paper. The idea is to prepare a form of a master plan record which uses the visual 3D language and may be accessed via World Wide Web pages. The paper formulates the assessments for the software described above and examines the possibility to create an application. The trial to prepare a web based service using the flash and shockwave technology is presented.

title Interacción icónica verbal en interfases digitales [Verbal Iconical Interaction in Digital Interfaces]
source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary Based on principles of usability and semantics, to analyze the structure that sub lies in the design of a graphical digital interfaces, it.s the main focus of this paper. Besides it tries to provide the criteria for designers of interfaces, and helps them to understand certain items that can give them the tools with they can generate in the common user, confidence and freedom in the use of an interface.
