summary This paper presents research in computer modeling that ARIAM team of the school of architecture of Paris La Villette has been developing for several years. One of the aims of this research group is to develop computer systems that assist architects in modeling existing buildings or monuments from heterogeneous documents or data as drawings plans, sections, photos, measures taken on site etc. In spite of advances in computer recognition it’s a long way to have a system that could automatically recognize, from any bitmap document or photo, relevant architectural objects and automatically build the model these documents represent. However, if we could define a knowledge base about a particular domain, it would be possible to develop a system that could interpret specific documents that represent some kind of building or monuments. But, even in such limited domain, it is difficult to build an exhaustive knowledge base and user-interactions are generally required. We argue that a user could mark relevant information on the documents and thus facilitate the process of interpreting. The system we propose has three components: a graphical user interaction tool, an analyzer of documents and user interactions, and a generative tool that produces the required model. As an illustration, the paper presents a system we have developed which assists an architect in modeling a 3D mesh of gothic vaults for a finite elements analysis.

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

title The Impact of 3D Digital Modeling on the 3D Design Aspects in Urban Design Plans
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 331-340

summary Some experts suggest that urban design plans in US cities may lack adequate coverage of the three-dimensional design aspects of the built environment. 3D digital models may help designers visualize and interact with design alternatives, large urban data sets, and 3D information more effectively, thus correcting this problem. Case studies of recent urban design plans that have used 3D digital models may indicate whether these technologies can increase the quality of the plan. This research discusses the role 3D urban models can play in supporting designers in addressing the 3D design aspects. A literature review focused on reviewing secondary sources to construct or adopt theoretical propositions against which the empirical data can be compared and contrasted. A case study involved investigating the methods with which 3D models have been used in developing a selected urban design plan. The content analysis of the case study refuted the premise that the plan would inadequately address 3D aspects and utilize 3D information, and indicated an effective usage of 3D modeling to analyze and represent most of the 3D and 2D information elements and issues. The results are consistent with a hypothesis that the effective usage of 3D modeling would result in the effective coverage of 3D information and issues. The effective usage of the model’s functionalities has improved the quality of the decision-making process through improving designers’ cognitive capabilities and providing a platform for communicating design ideas among and across design teams.

title Responsiveness and Social Expression; Seeking Human Embodiment in Intelligent Façades

summary This paper is based on a comparative analysis of some twenty-six intelligent building facades and sixteen large media-facades from a socio-psychological perspective. It is not difficult to observe how deployment of computational technologies have engendered new possibilities for architectural production to which surface-centeredness lies at that heart of spatial production during design, fabrication and envelope automation processes. While surfaces play a critical role in contemporary social production (information display, communication and interaction), it is important to understand how the relationships between augmented building surfaces and its subjects unfold. We target double-skin automated facades as a distinct field within building-services and automation industry, and discuss how the developments within this area are over-occupied with seamless climate control and energy efficiency themes, resulting into socially inert mechanical membranes. Our thesis is that at the core of the development of automated façade lies the industrial automation attitude that renders the eventual product socially less engaging and machinic. We illustrate examples of interactive media-façades to demonstrate how architects and interaction designers have used similar technology to turn building surfaces into socially engaging architectural elements. We seek opportunities to extend performative aspects of otherwise function driven double-skin façades for public expression, informal social engagement and context embodiment. Towards the end of the paper, we propose a conceptual model as a possible method to address the emergent issues. Through this paper we intend to bring forth emergent concerns to designing building membrane where technology and performance are addressed through a broader cultural position, establishing a continual dialogue between the surface, function and its larger human context.

title Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
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. 181-200.
summary The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

title Dynamical structural modeling A collaborative design exploration
source International Journal of Architectural Computing vol. 3 - no. 1, 27-42
summary This study is based on a generative performative modeling approach that engages architects and structural engineers in close dialogue. We focus on knowledge shared between engineers and architects to apply the Finite Element Analysis based structural design technique Evolutionary Structural Optimization [ESO] as a way to understand or corroborate the performance factors that are significant in determining architectural form. ESO is very close conceptually to the dynamical system of matter and forces of growth itself. It has parallels both mathematical and metaphorical with natural evolution and morphogenesis so it has been poignant to apply the approach to a formal architectural case study in which the generative influence of these processes is inherent.

source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 300-303
summary Traditionally, the teaching of digital design systems has been focused on the operative learning of software. However, this almost exclusively technical approach has leaded to a partial view of these systems, as well suited platforms to exploration of project’s possibilities. Consequently their relevance as a base for project representation and therefore as a useful instrument for conceptual exploration for design and experimental research of their processes have been undervalued. On the other hand, this restrictive perspective results in an important waste of the teaching possibilities lying in CAD software related with interdisciplinary teamwork. The following academic experience obeys to a new insight of how to teach these tools, based upon problem solving in Design by interdisciplinary students work teams from Architecture and Industrial Design. In this bet, the learning process is flexible, shared and collaborative, according to the requirements of each project, powered by the commitment of facing common goals. [Full paper in Spanish]

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

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

title A Computational Approach to the Reconstruction of Surface Geometry from Early Temple Superstructures
source International Journal of Architectural Computing vol. 3 - no. 4, 471-486
summary Recovering the control or implicit geometry underlying temple architecture requires bringing together fragments of evidence from field measurements, relating these to mathematical and geometric descriptions in canonical texts and proposing "best-fit" constructive models. While scholars in the field have traditionally used manual methods, the innovative application of niche computational techniques can help extend the study of artefact geometry. This paper demonstrates the application of a hybrid computational approach to the problem of recovering the surface geometry of early temple superstructures. The approach combines field measurements of temples, close-range architectural photogrammetry, rule-based generation and parametric modelling. The computing of surface geometry comprises a rule-based global model governing the overall form of the superstructure, several local models for individual motifs using photogrammetry and an intermediate geometry model that combines the two. To explain the technique and the different models, the paper examines an illustrative example of surface geometry reconstruction based on studies undertaken on a tenth century stone superstructure from western India. The example demonstrates that a combination of computational methods yields sophisticated models of the constructive geometry underlying temple form and that these digital artefacts can form the basis for in depth comparative analysis of temples, arising out of similar techniques, spread over geography, culture and time.

summary 4D CAD systems are used by contractors for visually checking the construction process. To enable simulation of the construction process, the construction planner links building components from a CAD model with the activities from a project planning. In this paper we describe a method to generate a project planning directly from a CAD model using basic construction knowledge. A case study is discussed briefly to show the current results and the shortcomings. Finally an outlook is presented on a more advanced implementation that is (also) useful for designers.

title The continuity style in architectural dynamic visualization
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 468-472
summary The term “continuity style” in cinema refers to a collection of cinematic conventions aiming at a realistic viewing experience without drawing attention to the elements of illusion used in the representation of 3D space on 2D film. The continuity style underlies the majority of narrative films produced to date and has had a significant influence on other genres, including documentaries. Despite the similarities in purpose, architectural filmmaking owes little to the cumulative knowledge of filmmaking encapsulated in the continuity style. While narrative films focus on the viewing experience, architectural animation tends to be dominated by integral 3D building models. We propose that key elements of the continuity style could be applied to architectural dynamic visualization in order to enhance both lay perception of architectural space and professional analysis of design intentions. These elements refer to four primary areas of architectural dynamic visualization: narrative, camera use, lighting and model structure.

summary During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi-EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

title Collective Pavilions: A Generative Architectural Modelling for Traditional Chinese Pagoda
source Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 129-138
summary This paper investigates generative architectural modelling for traditional Chinese architecture and aims to explore and extend the potential of adaptive computing for architectural design methods. The design manners analysis of traditional pagodas architectures is made in a holistic view and under historical perspective. We propose a descriptive model and generative system for the design of traditional Chinese pagodas, by which each pagoda is defined as a collection of style-matched and form-coordinated pavilions and described by both topological graphs and variant geometrical units. Our approach models both of the building geometry and space organization/spatial patterns of pagodas separately. The generative mechanism consists of a framework of grammar-based design and parametric, recursive shape computation. Accordingly, the generative algorithm is also made of two levels, the topology of spatial patterns and the shape geometrical parameters that characterize pavilion variations. The algorithm for computing the former is based on GP (Genetic Programming) and the latter GA (Genetic Algorithms). To explore the collective behaviour of a group of pavilions, multi-agent modelling approach is incorporated in composition patterns search. A prototype system, 'glPagoda', using the OpenGL graphics library for rendering and visualization, has been developed and implemented on PC windows platform.

title A METHOD FOR REAL TIME SPATIAL ANALYSIS OF SOUND VIA MODELING IN A CAD ENVIRONMENT, BASED ON ACOUSTICAL MEASUREMENTS
source 14th European Colloquium on Theoretical and Quantitative Geography,September 9-13, 2005, Tomar, Portugal
summary Typical modeling systems for spatial analysis employ data that represent the visual part of a landscape (e.g. relief and morphology), combined with other data about specific attributes (depending on the aims of an application). Thus, in a modeling environment, each place is described by a variety of properties that are not always visible. More of those “hidden” properties require special sensors and/or instruments to be captured and sometimes make their presence evident through human senses, such is sound. The present study takes advantage of wide spread technologies (such as GPS, VHF telecommunications and field sensors) and methodologies that are commonly used in telegeoprocessing – telegeomonitoring in order to simulate an existing acoustic environment. The aim is to acquire real time data about the sound (referenced to a particular area) and manipulate them in a CAD environment with purpose to visualize the sound influence in a specific landscape. Specifically it is proposed a method that transfers spatial data (collected from the field), directly into a modeling system (in the office, or in situ). In sequence the data is processed adequately to feed the modeling system that describes the current sound intensity of a place.

title On Recovering the Surface Geometry of Temple Superstructures
source CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 2, pp. 253-258
doi https://doi.org/10.52842/conf.caadria.2005.253
summary The application of computational techniques to the analysis of heritage artifacts enables scholars to bring together diverse fragments of surviving evidence, construe “best-fit” strategies and unearth implicit or hidden relationships. This paper reports a hybrid approach for recovering the surface geometry of temples. The approach combines physical measurements, architectural photogrammetry and generative rules to create a parametric model of the surface. The computing of surface geometry is broken into three parts, a global model governing the overall form of the superstructure, local models governing the geometry of individual motifs and finally the global and local models are combined into a single geometry. In this paper, the technique for recovering surface geometry is applied to a tenth century stone superstructure: the temple of Ranakdevi at Wadhwan in Western India. The global model of the superstructure and the local model of one individual motif are presented.

title Automation of Building Code Analysis: Characteristics, Relationships, Generation of Properties and Structure of Various Models
source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 607-622
summary This paper is considered as the second part of what has been presented in ASCAAD 2005, titled "Issues of Integrating Building Codes in CAD", that discussed the conceptual framework of automating the building code analysis process. The proposed framework was composed of three digital interrelated models; Building Code Model (BCM), Building Data Model (BDM) and Computer Aided Building Code Analysis of Design (CABCAD) Program. The International Building Code (IBC) has been selected to understand the characteristics of building codes and to develop the BCM. This paper aimed to discuss the concepts behind the building code requirements, characteristics of building code analysis process, hierarchical relationship between various objects in the BCM and BDM.
