summary	This paper presents the example of the reconversion of an important tram station from the origins of electricity in Portugal that was still in use until the late 1990’s but became redundant since then. Its significant urban presence and the importance of preserving the memory of the old trams that were still in use some years ago in Lisbon, led to an innovative solution, combining public value and heritage protection. In 2011, the Lisbon City Council agreed to give the building and its site for university use, namely to be transformed into a student’s facility, as a study, leisure, recreational and cultural space of the IST, open 24h a day. This new university building, located just one block away from the traditional IST compound, was called IST Learning Center and extended the notion of campus outside its walls and into the city’s urban fabric.

title	A Hypermedia Model for Supporting Energy Design in Buildings
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 39-49

summary	Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.

title	A Procedural Model for Integrating Physical and Cyberspaces in Architecture
source	Doctoral dissertation, University of Plymouth, Plymouth, U.K
summary	This dissertation articulates opportunities offered by architectural computation, in particular the digital simulation of space known as virtual reality (VR) and its networked, social variant cyberspace. Research suggests that environments that hybridize technologies call for a conception of space as information, i.e. space is both a product of and tool for cognition. The thesis proposes a model whereby architecture can employ this concept of space in creating hybrids that integrate physical and cyberspaces.The dissertation presents important developments in architectural computation that disclose concepts and values that contrast with orthodox practice. Virtual reality and cyberspace, the foci of this inquiry, are seen to embody the more problematic aspects of these developments. They also raise a question of redundancy: If a simulation is good enough, do we still need to build? This question, raised early in the 1990's, is explored through a thought experiment - the Library Paradox - which is assessed and critiqued for its idealistic premises. Still, as technology matures and simulations become more realistic the challenge posed by VR/cyberspace to architecture only becomes more pressing. If the case for virtual idealism seems only to be strengthened by technological and cultural trends, it would seem that a virtual architecture should have been well established in the decade since its introduction.Yet a history of the virtual idealist argument discloses the many difficulties faced by virtual architects. These include differences between idealist and professional practitioners, the failure of technology to achieve its proponents' claims, and confusion over the meaning of virtual architecture among both architects and clients. However, the dissertation also cites the success of virtual architecture in other fields - Human Computer Interface design, digital games, and Computer Supported Collaborative Work - and notes that their adoption of space derives from practice within each discipline. It then proposes that the matter of VR/cyberspace be addressed from within the practice of architecture, a strategy meant to balance the theoretical/academic inclination of previous efforts in this field.The dissertation pursues an assessment that reveals latent, accepted virtualities in design methodologies, instrumentation, and the notations of architectural practices. Of special importance is a spatial database that now pervades the design and construction processes. The unity of this database, effectively a project's cyberspace, and its material counterpart is the subject of the remainder of the dissertation. Such compositions of physical and cyberspaces are herein called cybrids. The dissertation examines current technologies that cybridize architecture and information technology, and proposes their integration within cybrid wholes. The concept of cybrids is articulated in seven principles that are applied in a case study for the design for the Planetary Collegium. The project is presented and critiqued on the basis of these seven principles. The dissertation concludes with a discussion of possible effects of cybrids upon architecture and contemporary culture.

title	The Computerized Design Firm

summary	This paper is not just about the future of computerized design practice. It is about what to do today in contemplation of tomorrow-the issues of computercentered practice and the courses of action open to us can be discerned by the careful observer. The realities of computerized design practice are different from the issues on which design education still fixes its attention. To educators, the present paper recommends further clinical research on computerized design firms and suggests that case studies on the matter be developed and utilized as teaching material. Research conducted by the author of this paper indicates that a new form of design firm is emerging-the computerized design firm-totally supported and augmented by the new information technology. The present paper proceeds by introducing an abridged case study of an actual totally electronic, computerized design practice. Then, the paper concentrates on modelling the computerized design firm as an intelligent system, indicating non-trivial changes in its structure and strategy brought about by the introduction of the new information technology into its operations - among other considerations, different strategies and diverse conceptions of management and workgroup roles are highlighted. In particular, this paper points out that these structural and strategic changes reflect back on the technology of information with pressures to redirect present emphasis on the individual designer, working alone in an isolated workstation, to a more realistic conception of the designer as a member of an electronic workgroup. Finally, the paper underlines that this non-trivial conception demands that new hardware and software be developed to meet the needs of the electronic workgroup - which raises issues of human-machine interface. Further, it raises the key issues of how to represent and expose knowledge to users in intelligent information - sharing systems, designed to include not only good user interfaces for supporting problem-solving activities of individuals, but also good organizational interfaces for supporting the problem-solving activities of groups. The paper closes by charting promising directions for further research and with a few remarks about the computerized design firm's (near) future.

title	A digital Procedure of Building Construction: A practical project
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

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.

summary	Neural networks of PDP (parallel distributed processing), models of computation are based on mathematical models of neural processes. The authors explore the application of PDP to simple spatial reasoning in computer-aided design. Knowledge that provides a mapping from performances to design descriptions can be encoded into PDP systems in the form of learned patterns. The implementation of a simple PDP pattern associator is described. The system is shown to facilitate a rudimentary kind of associative or analogical reasoning. It also facilitates reasoning where only incomplete information is available. There are important concerns in design reasoning

title	Virtual Reality and the Future of Publishing Archaeological Excavations: the multimedia publication of the prehistoric settlement on Tsoungiza at Ancient Nemea
source	New York: The Metropolitan Museum of Art
summary	The Nemea Valley Archaeological Project is a study of settlement and land use in a regional valley system in Greece extending from the Upper Paleolithic until the present. Active field research was conducted by four teams between 1981 and 1990. The first component was a regional archaeological survey. Second, and closely related to the first, was a social anthropological study of modern settlement and land use. Next was a team assigned to excavate the succession of prehistoric settlements of Ancient Nemea on Tsoungiza. Last, historical ecologists, a palynologist, and a geologist formed the environmental component of the research. As a result of advances in electronic publishing, plans for the final publication of the Nemea Valley Archaeological Project have evolved. Complete publication of the excavation of the prehistoric settlements of Ancient Nemea on Tsoungiza will appear in an interactive multimedia format on CD/DVD in Fall 2000. This project is planned to be the first electronic publication of the American School of Classical Studies at Athens. We have chosen to publish in electronic format because it will meet the needs and interests of a wider audience, including avocational archaeologists, advanced high school and college students, graduate students, and professional archaeologists. The multimedia format on CD/DVD will permit the inclusion of text, databases, color and black-and-white images, two and three-dimensional graphics, and videos. This publication is being developed in cooperation with Learning Sites, Inc., which specializes in interactive three-dimensional reconstructions of ancient worlds http://www.learningsites.com. The Nemea Valley Archaeological Project is particularly well prepared for the shift towards electronic publishing because the project's field records were designed for and entered in computer databases from the inception of the project. Attention to recording precise locational information for all excavated objects enables us to place reconstructions of objects in their reconstructed architectural settings. Three-dimensional images of architectural remains and associated features will appear both as excavated and as reconstructed. Viewers will be able to navigate these images through the use of virtual reality. Viewers will also be able to reference all original drawings, photographs, and descriptions of the reconstructed architecture and objects. In this way a large audience will be able to view architectural remains, artifacts, and information that are otherwise inaccessible.

source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 239-246
summary	The initial purposes of this work were to build a 3D model of the old city of Messina and to reconstruct a walk through it; to understand the "Ghost city," the parts that form it, and the rules of its plan, which are explicit in some cases but hidden most of the time; to measure its space, appreciate the similarities to and differences from modern city plans, and use the information to improve the plans of tomorrow. It might seem a useless study of a nonexistent city, and yet during the months of detailed work, of patient reconstruction from the surveys and photographs of the city destroyed in 1908, we began to consider how it was still possible to obtain spatial values of and to project behaviors in the lost city, in other words, to practice tests on memory that are very interesting for people working in a context in which memory no longer exists. The work presented here is the first stage of a more complex research project still to be carried out on Messina as it was at the end of the nineteenth century. Here we constructed a 3D model of some parts of the city prior to the earthquake of 1908 and made a five-minute video, using cartoon techniques, of an "impossible" walk through the city. The fragments of the city were reconstructed from available documentary sources, primarily photographic images, which tended to be of the most important places in the city.

source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 215-228
summary	In this paper we present a model for handling design information in the early design phases. This model can be used for representing both vague and exact defined information. The first part describes the difficulties involved in using CAD in the architectural design process and the characteristics of that process. Then we give a description of the design information and its representation during the design process. Next an overview of the architectural design process describes how design information is added and manipulated during the design process in order to achieve an effective result. Finally, we include a brief description of a simple prototype program to illustrate how this theory acts in practice.

title	Where the Footprints Lead: Tracking down other roles for social navigation
source	Social Navigation of Information Space, eds. A. Munro, K. H. and D Benyon. London: Springer-Verlag, pp 15-34
summary	Collaborative Filtering was proposed in the early 1990's as a means of managing access to large information spaces by capturing and exploiting aspects of the experiences of previous users of the same information. Social navigation is a more general form of this style of interaction, and with the widening scope of the Internet as an information provider, systems of this sort have rapidly moved from early research prototypes to deployed services in everyday use. On the other hand, to most of the HCI community, the term social navigation" is largely synonymous with "recommendation systems": systems that match your interests to those of others and, on that basis, provide recommendations about such things as music, books, articles and films that you might enjoy. The challenge for social navigation, as an area of research and development endeavour, is to move beyond this rather limited view of the role of social navigation; and to do this, we must try to take a broader view of both our remit and our opportunities. This chapter will revisit the original motivations, and chart something of the path that recent developments have taken. Based on reflections on the original concerns that motivated research into social navigation, it will explore some new avenues of research. In particular, it will focus on two. The first is social navigation within the framework of "awareness" provisions in collaborative systems generally; and the second is the relationship of social navigation systems to spatial models and the ideas of "space" and "place" in collaborative settings. By exploring these two ideas, two related goals can be achieved. The first is to draw attention to ways in which current research into social navigation can be made relevant to other areas of research endeavour; and the second is to re-motivate the idea of "social navigation" as a fundamental model for collaboration in information-seeking."

title	Interactive design of parameterized 3D models by direct manipulation
source	Delft University of Technology
summary	The practical applicability of a computer-aided design system is strongly influenced by both the user interface and the internal model representation. A well designed user interface facilitates the communication with the system by offering an intuitive environment for for specification and representation of model information. An internal model representation, capable of storing geometric, topological and hierarchical dependencies between components in a model, increases the efficiency of the system by facilitating modification and elaboration of the model during the different stages of the design process. The subject of this thesis is the integration of a high level parameterized model representation with direct manipulation interface techniques for the design of three-dimensional objects. A direct manipulation interface enables the user to specify a model by interaction on a graphical representation, as an alternative for an abstract and error-prone apha-numerical dialogue style. A high level model representation is obtained by using a procedural modeling language with general purpose control structures, including arithmetic and logical expressions, repetition, conditionals, functions and procedures, and dedicated data types such as coordinate systems, geometric primitives and geometric constraints. The language interpreter is interconnected with a graphical interface, an incremental constraint solver and a geometrical modeler, using visual programming techniques. The developed techniques are implemented in a modeling system called GeoNode. The system incorporates paradigms of object-oriented design, with respect to both the user interface and to the system implementation. The applicability of the presented techniques is illustrated by examples in application domains such as solid modeling, kinematic analysis, feature modeling and top-down design.

summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.
