summary	The value of material in architectural practice is determined not by its character but by functional performance and economy. In early modernist thought, part of this motivation was to liberate construction from the ‘burden’ of aesthetic speculations and return it simply to the concerns of building. Any artistic agenda became embedded in the economic and productive processes of the project. Authenticity emerged out of the need to focus on the essentials and reject the superfluous. However, this demand for truth in materials has long since been compromised by the climatic requirements of building enclosure. Most contemporary practice in architecture is derived from principles of cladding where the ‘essential nature’ of a complex building requires concealment. The communication of the building is expressed in the refinement of the layers that make up the surface. This shift from the emphasis on making and the idea of ‘material’ in architecture, to one of perception and ‘materiality,’ has an important corporeal dimension that parallels the material aesthetic practices developed in art and sculpture in the 1960s. In this sense, Fabrication carries an ‘untimely’ dimension. This paper proposes to look at the work of a broad range of architects, both well-known and not so well-known, in light of these artistic-based approaches to materiality. Digital fabrication opens a new chapter on this debate and it remains to be seen how this economically useful approach to construction changes, once architects investigate the visual characteristics of materials and methods of fabrication.

title	Future Space Cities@Universe (Digi-City Vision)
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	A template for the future city has been carved into the heavens. Ever since the beginning of humankind, we have looked to the sky for the opportunity to make a new start in our imperfect world. Between the stars and the darkness we have imagined utopias beyond the reach of our travel technologies, colonizing space with our fantasies. Now we are in the first stages of an electronic revolution, but in the future 50 years later we will be in a mega-digital era which we have to predict, work and search for the reality of that future. Our planet is recently over loaded with different problems, such as pollution, population, nature disasters. Our vast speed of technology and the curiosity of discovering the invisible, leads to study and find out the nearest Future Space Architecture. With the vast acceleration of technology and digital life, we should start to predict the future architecture on, into or behind the Earth. This paper is one of many perceptions of life and architecture behind the Earth in the digital era, Digi-City Vision.

source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	This study is placed on the research line of Pedagogical practice and formation of the educator, which theme is related to learning in virtual worlds. The article presents and discusses some aspects of the process of approaching subjects (teachers) to a Virtual World, at a first moment, in a level of exploration, experimentation, interaction as a user, and, at a second moment as a creator, an author of a Virtual World, AWSINOS. The present study takes part of a exploratory/experimental research of qualitative nature that looks for the creation of virtual worlds for the continued qualification online and focuses on the investigation of socio-cognitive behaviors of subjects during their organization as a group and during the activity of building and using these worlds.

title	Computer Aided Sustainable Design
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
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	How to Construct an Audience in Collaborative Design - The Relationship Among which Actors in the Design Process
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 426-434

summary	The features of complexity in architectural design have now been clarified. Complexity, intrinsic in architectural work, has increased in recent years as in all other fields of human endeavour – social, economic and cultural. In the specific case of architectural design, the most significant factors in this regard consist of the large number of actors, the numerous disciplines involved, technological innovation, regulations and rules governing the design process and the various different design aims. In order to address this complex of problems, long-term research based on the Collaborative Design paradigm, CD, is now being carried out. In it, thanks to the reciprocal exchange of information, the complementary nature of the knowledge possessed by the various actors, and the contemporary nature of the design action by the various actors on the same components, positive effects are exerted on the design as a whole. The latter thus gains in coherence and in improved integration among the design solutions proposed by the various actors. In CD all the actors are involved from the outset of the design work and are helped by distributed Knowledge Bases (KBs) and Intelligent Assistants (IAs). In this case it may happen that information and knowledge automatically exchanged among KBs (through the IAs) are excessive and/or not addressed to the right actors. How can information redundancy be avoided, and how can the flow of information sent over the network be controlled? The present paper introduces and defines the concept of „Audience“, that is, the group of actors to which it is permitted to send information concerning non respected requirements and the „reduced Audience“ to which to send the knowledge needed to overcome the difficulties encountered.

title	La Arquitectura como Extensión Fenotípica Humana - Un Acercamiento Basado en Análisis Computacionales [Architecture as human phenotypic extension – An approach based on computational explorations]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 56-60
summary	The study describes some of the aspects tackled within a current Ph.D. research where architectural applications of constructive, structural and organization processes existing in biological systems are considered. The present information processing capacity of computers and the specific software development have allowed creating a bridge between two holistic nature disciplines: architecture and biology. The crossover between those disciplines entails a methodological paradigm change towards a new one based on the dynamical aspects of forms and compositions. Recent studies about artificial-natural intelligence (Hawkins, 2004) and developmental-evolutionary biology (Maturana, 2004) have added fundamental knowledge about the role of the analogy in the creative process and the relationship between forms and functions. The dimensions and restrictions of the Evo-Devo concepts are analyzed, developed and tested by software that combines parametric geometries, L-systems (Lindenmayer, 1990), shape-grammars (Stiny and Gips, 1971) and evolutionary algorithms (Holland, 1975) as a way of testing new architectural solutions within computable environments. It is pondered Lamarck´s (1744-1829) and Weismann (1834-1914) theoretical approaches to evolution where can be found significant opposing views. Lamarck´s theory assumes that an individual effort towards a specific evolutionary goal can cause change to descendents. On the other hand, Weismann defended that the germ cells are not affected by anything the body learns or any ability it acquires during its life, and cannot pass this information on to the next generation; this is called the Weismann barrier. Lamarck’s widely rejected theory has recently found a new place in artificial and natural intelligence researches as a valid explanation to some aspects of the human knowledge evolution phenomena, that is, the deliberate change of paradigms in the intentional research of solutions. As well as the analogy between genetics and architecture (Estévez and Shu, 2000) is useful in order to understand and program emergent complexity phenomena (Hopfield, 1982) for architectural solutions, also the consideration of architecture as a product of a human extended phenotype can help us to understand better its cultural dimension.

title	Building a Synthetic Cognizer
source	Design Computation Cognition conference 2004, MIT
summary	Understanding ‘space’ as a structured and dynamic system can provide us with insight into the central concept in the architectural discourse that so far has proven to withstand theoretical framing (McLuhan 1964). The basis for this theoretical assumption is that space is not a void left by solid matter but instead an emergent quality of action and interaction between individuals and groups with a physical environment (Hillier 1996). In this way it can be described as a parallel distributed system, a self-organising entity. Extrapolating from Luhmann’s theory of social systems (Luhmann 1984), a spatial system is autonomous from its progenitors, people, but remains intangible to a human observer due to its abstract nature and therefore has to be analysed by computed entities, synthetic cognisers, with the capacity to perceive. This poster shows an attempt to use another complex system, a distributed connected algorithm based on Kohonen’s self-organising feature maps – SOM (Kohonen 1997), as a “perceptual aid” for creating geometric mappings of these spatial systems that will shed light on our understanding of space by not representing space through our usual mechanics but by constructing artificial spatial cognisers with abilities to make spatial representations of their own. This allows us to be shown novel representations that can help us to see new differences and similarities in spatial configurations.

title	COMPUTER DESIGN OF REPEATING HYPERBOLIC PATTERNS
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 83-90.
summary	From antiquity, humans have created 2-dimensional art on flat surfaces (the Euclidean plane) and on surfaces of spheres. However, it wasn't until about 50 years ago that designers have created art in the third "classical geometry", the hyperbolic plane. Inspired by a diagram from the mathematician H. S. M. Coxeter, the graphic artist M. C. Escher became the first person to design such patterns, performing all the needed constructions laboriously by hand. In order to exhibit the true hyperbolic nature of such art, the pattern must exhibit symmetry and repetition. It seems natural to use a computer to avoid the tedious hand constructions performed by Escher. This was our goal: to design and implement a computer program to create repeating hyperbolic patterns.

title	AGENTS OF RISK: EMBEDDING RESISTANCE IN ARCHITECTURAL PRODUCTION

summary	In its most common usage, the term fabrication calls to mind industry and production. For architecture, fabrication and industry have been defining aspects of modern practice. While dependant on the dimensional and temporal standards of industry, modernists were preoccupied with the limitations imposed by the generic restrictions of mass production. When we make, instead of predetermining action, we discover a map of engagement. We play by challenging and resisting material. It in turn, reveals an intentional resistance that provokes yet another challenge, and on and on and on. In fact, craft excels in the less-than-ideal situations. When challenged by aberrant materials, geometry and craft are forced into innovative discovery: a knot of reaction wood within an otherwise homogeneous surface would force a novel adaptation of geometry generated by the imperfection. How, then, do we integrate the indeterminate cycle of craft and invention into a design process transformed by tools entirely reliant on prediction and the (virtual and real) homogeneity of materials? Is it reasonable to introduce an element of risk into the realm of digital fabrication equivalent to the auto-generative sabotage of Signwave’s Auto Illustrator? This paper reflects on the nature of material craft in the realm of digital fabrication. It will look both at the history and the contemporary opportunity of generative art and automata and their subversive (yet essential) relationship to the making of architecture.

summary	Project Alliances is a new alternative to A/E/C traditional project delivery systems, especially in the commercial building sector. The interoperable model of Co-design process and systems characteristics that is required to reduce the adversarial nature of most construction projects. Interoperable Co-Design System was just used successfully to complete the Si-soft Research Center of Taiwan. This project-alliancing project was analyzed as a case study to evaluate the validity of the system. Three key paradigms of the Co-Design were reviewed and numerous examples from the management of this project were cited that support the theoretical recommendations of this model. It was concluded that the system use wild client/server network architecture embedded with peer-to-peer agent technology to provide an open, familiar and easily extended co-design system.

title	Visual Design Thinking in the Design Process as Impacted by Digital Media

summary	Exploring design ideas, through two dimensional and three dimensional forms, is the basis of design exploration and visual design thinking during the design process. Imagining how drawings and models (be it manual or digital) will be presented in reality is the essence of visual design thinking. By the beginning of the 20th Century, architecture has become more three dimensional in design exploration and in representation. This transition to three dimensions makes the processes of visual design thinking more related to digital media. The nature of media, utilized by architects, affects design-exploration processes. The research investigates both the processes of visual design thinking and the interrelation between visual design thinking and digital media, in order to shed more light on how digital media should be introduced to students of architecture.

title	An Evaluation of Neural Spatial Interaction Models Based on a Practical Application

summary	One of the serious problems faced by the Brazilian municipalities is the scarcity of resources for building education infrastructure. This asks for an optimal allocation of the available resources that includes, among other things, a rational spatial arrangement of the supply points (i.e., schools) in order to increase the demand coverage (i.e., students). If it is possible to foresee the regions where the demand is going to be concentrated, it is then possible to plan the location of new facilities and to assess the impact on the future level of service of the entire system. Considering that one of the consequences of the location-allocation process is the distribution of trips from demand points to supply points throughout the city, therefore affecting the overall intraurban accessibility conditions to essential services such as education, there is a strong need of models that planners can rely on to predict the future trip distribution patterns. As a result, the objective of this work was to evaluate the performance of Artificial Neural Networks (ANN) when applied to spatial interaction models, the so-called Neural Spatial Interaction Models. This was done in a practical context, in contrast to the more theoretical works commonly found in literature. The practical application showed that the neural spatial interaction model had different performances when compared to the traditional gravity models. In one case the neural models outperformed the gravity models, while on the other case it was just the opposite. The explanation for this may be in the data or in the ANN model formulation, as discussed in the conclusions.

source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	An exploration on the analogy-based idea generation process in industrial design is reported. In particular we try to identify relationships between the sketching process and the analogy building in order to elicit requirements for a supporting software. We use concurrent think aloud protocols to obtain experimental data and an extension of a proved content oriented schema to analyze them. Statistical analysis on segments containing .analogical chains. found relations between analogical and design actions that allow us to support the hypothesis that the sketch seems to be more useful for helping the analytical aspects of the analogical making (i.e. to code a situation in terms of higher order relations) than the synthetic ones (i.e. to identify an analogy source). Results were interpreted as software requirements for a Computer Aided Design Application.

source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 248-253
summary	Recent developments in digital technologies and smart materials have created new opportunities and are suggesting significant changes in the way we design and build architecture. Traditionally, however, there has always been a gap between the new technologies and their applications into other areas. Even though, most technological innovations hold the promise to transform the building industry and the architecture within, and although, there have been some limited attempts in this area recently; to date architecture has failed to utilize the vast amount of accumulated technological knowledge and innovations to significantly transform the industry. Consequently, the applications of new technologies to architecture remain remote and inadequate. One of the main reasons of this problem is economical. Architecture is still seen and operated as a sub-service to the Construction industry and it does not seem to be feasible to apply recent innovations in Building Technology area. Another reason lies at the heart of architectural education. Architectural education does not follow technological innovations (Watson 1997), and that “design and technology issues are trivialized by their segregation from one another” (Fernandez 2004). The final reason is practicality and this one is partially related to the previous reasons. The history of architecture is full of visions for revolutionizing building technology, ideas that failed to achieve commercial practicality. Although, there have been some adaptations in this area recently, the improvements in architecture reflect only incremental progress, not the significant discoveries needed to transform the industry. However, architectural innovations and movements have often been generated by the advances of building materials, such as the impact of steel in the last and reinforced concrete in this century. There have been some scattered attempts of the creation of new materials and systems but currently they are mainly used for limited remote applications and mostly for aesthetic purposes. We believe a new architectural material class is needed which will merge digital and material technologies, embedded in architectural spaces and play a significant role in the way we use and experience architecture. As a principle element of architecture, technology has allowed for the wall to become an increasingly dynamic component of the built environment. The traditional connotations and objectives related to the wall are being redefined: static becomes fluid, opaque becomes transparent, barrier becomes filter and boundary becomes borderless. Combining smart materials, intelligent systems, engineering, and art can create a component that does not just support and define but significantly enhances the architectural space. This paper presents an ongoing research project about the development of new class of architectural wall system by incorporating distributed sensors and macroelectronics directly into the building environment. This type of composite, which is a representative example of an even broader class of smart architectural material, has the potential to change the design and function of an architectural structure or living environment. As of today, this kind of composite does not exist. Once completed, this will be the first technology on its own. We believe this study will lay the fundamental groundwork for a new paradigm in surface engineering that may be of considerable significance in architecture, building and construction industry, and materials science.

doi	https://doi.org/10.52842/conf.caadria.2017.551
summary	This paper will discuss and investigate the issues with the concept of 'glitch' in architecture. There are currently two definitions that sit in a symbiotic relationship with each other; Moradi's (2004) and Menkman's (2011). This paper will explore the implications of these two approaches, while investigating the possibility of a third, unique definition (the encoded transform), and what effect they have on the possibility for a 'glitch architecture'. The paper will then focus on the glitches' capacity to be disruptive within the design process. In the context of architecture, it has been previously argued that the inclusion of glitches within a design process can easily create a process that does not 'converge' to a desired design outcome, but instead shifts haphazardly within a set of family resemblances (Austin & Perin 2015). Further to this, it will be revealed that this 'divergent' quality of glitches is due to the encoded nature of architectural production.

summary	We are presenting design ideas, technical innovation, and fabrication expertise that address crucial issues. Authors investigate how to effectively design and practice architecture with automated prototyping and manufacturing. We want to understand where this might lead, and how it might change the nature of architecture itself. We are just beginning to discover the opportunities to be found in integrating automated fabrication within the practice of architecture. At the same time, the new century has brought very mixed perspectives on confident Modern progress. A cautious scrutiny of 'innovation' is needed. Fabrication is an old word with the straightforward meaning, to make. The roots of the word lead to the origins of architecture. Making has been considered a virtue by ancient writers and modern politicians alike. Fabrication (and homo faber, 'one who makes') have served as fundamental terms that constitutions and contract laws have been built upon. Shaping and working with materials is at the core of Western civilization. However at a point in human history where nature is steadily being replaced by human artifice, the consequences of making are far from simple. Whether for good or ill, our new fabricated environment is transforming the world.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
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 ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô 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‚Äôs 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	Designing is largely a process of (inter)active imaging. The evolvement of a design concept from preliminary design proposal towards spatial and material environment generally follows an uncertain path through uncharted landscape; a journey of exploration which requires both rational and creative consideration, frequently involving the interchange of information within a design team and collaboration with representatives from different contributing disciplines. Designs are conceived, worked out and specified step by step (roughly speaking from ‘rough to fine’) in iterative design ‘loops’. All the time the designer tries to determine which ‘course’ should be taken, by considering reference material, by reflecting on conceptions developed previously and by generating specific options aimed at furthering the ‘concretisation’ of the end product. In the course of such a trajectory, visual information is continually being developed, selected, tested, and subsequently either discarded or perfected. From early times architects have been considered not only as knowledgeable ‘experts’ in the field of building as a craft, but also as ‘creative directors’ of such development processes. The architect should be capable of not only conjuring up visions of the future spatial and material form of the building, but also of conveying these to the other ‘actors’ involved in the initiation and building process. Such ‘sharing’ of information is necessary in order to generate sufficient understanding, consensus, enthusiasm, as well as means. To become more than ‘figments of the imagination’, the designer’s ideas need to be ‘pinned down’ (even if they are not yet entirely finished) and communicated by using some form of reliable – and preferably readable – ‘language’ for design development and communication.

title	View from the Road: Environmental Simulation for the Fractal City of Rhine Ruhr
source	Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 43-47
summary	Highway seems to be more an issue of traffic planning than of urban design. But the highway can be a very important factor for the modern city pattern. Highways shape the spatial form of the fractal city. The modern highway can define new cores outside and “interior edges” within the city. Seen as a planning tool, highways are the great neglected opportunity in city and regional design. The 1st Architecture Biennial, 1ab, taking place from May 2003 to July 2003 in Rotterdam, explores the creative potentials of modern highways worldwide. An international research team discovered the spatial functions of highways in modern agglomerations. This lecture will give an overview of the results of the worldwide analyses and the design projects that had been undertaken. Both authors are members of the German research team. The German team examined the A 42 running through the Ruhrgebiet, a former coal and steal area in western Germany. The Ruhr Area is converting from an industrially orientated region to an agglomeration of high technology and science. But the regional image remains the same due to the fact that the changes cannot be seen, neither physically, nor from the road. Here, the highway could be used as a catalyst supporting and structuring the spatial changes to make them more legible for the people of Rhine-Ruhr. The nature becomes the most important tool of highway design. Landscape forms a linkage between the different cities of the region. Together with the A 40 and other local highways the region becomes the most important (and largest) public space of the new Rhine-Ruhr. The highway seen as a work of urban art can be designed only from the perspective of the driving car.

title	STUDY ON COMPUTER-AIDED DESIGN SUPPORT OF TRADITIONAL ARCHITECTURAL THEORIES
source	Technische Universität München
summary	The research presented in this thesis describes a computer-aided design support of traditional architectural theories. Traditional architectural theories in western architecture have been considered as a basis for answering the fundamental questions of architecture: proportion, symmetry, colour, harmony and so on. In particular, the aesthetic aspect of these theories has been one of many important architectural aspects, and which is concerned with the field of architecture in determining the beauty of architectural form. The most significant role of the traditional theories in architecture is to maintain unity, to avoid chaos and then to achieve harmony in a design, using some specific design principles. However, current technology-guided constructions tend to neglect often the importance of these theories due to the standardization of building elements, due to mechanically-prepared construction and the reducing completion costs, etc. Thus, this research proposes a design support system as a design assistant that gives an intelligent advice on architectural design, using analytical design- and ordering- principles of traditional theories for the optimization of the architectural design from the aesthetic perspective. To evaluate the aesthetic quality of an architectural design, this system is implemented in the AutoCAD environment, using the AutoLISP. It is applied so as to explain and develop aesthetic qualities of a design. Designs proposed by this system include optimum designs, which are based on the traditional architectural theories, and new ones which can be in future connected to information models. To do this, the definition of information about building elements is accomplished by using the neutral format EXPRESS and EXPRESS-G for such application systems. The results of the application system are presented, such as the easily generating and quickly conceptualising of an object model, the checking of the aesthetic value of the design during the various design phases, the helping to find direction during rational searching for a solution. The user can easily appreciate the usefulness of the proposed system as a set of tools for searching for rational architectural aesthetics and formal solutions at different design-stages. It is to be hoped that a new "traditional" fundamental of architecture, such as the proposed system, incorporating CAAD systems, will find its place among new technological methods in the AEC industry and so help to bridge the gap between the value of traditional architecture and CAAD systems.
