title A Hypermedia Model for Supporting Energy Design in Buildings

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 Mastering Urban Network Intersection And Superimposition, in an Object-oriented Knowledge System Integrating Rules, Neurons and Processes
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Many networks cover the urban texture, either superimposed at a variable distance, or really intersecting, or even in interconnection. We briefly recall the HBDS model, working on persistent abstract data types associated to graphical representations and carrying algorithms expressing conditions to be verified and/or actions to be performed. HBDS is an integrated system too, including database, expert system dealing with fuzzy rules and facts, discrete simulation engine, and neural engine; it has a general purpose programming language. Any urban network is associated to a given prototype, according to the same scheme named prototype with more specific components. These prototypes allow to build the different thematic structures instantiations of the prototypes. All possible cases of arc intersection or "pseudo-intersection" (simple superimposition)or interconnection are obtained by, owing to new prototypes. Moreover, such (pseudo)-intersections are automatically recognized and processed without a human intervention, owing to classes ofconstraints and classes of rules. They deal with particular constraints concerning the location of some urban furniture, and rules concerning the way a cable or a pipe must follow according to thepre-existing other networks in a given area, the minimal distances, minimal or maximal depths, and some required equipments. Urban classes of (pseudo-)intersections inserted in the hyperciass"neuron", inheriting of neural features, may be used for automated learning of urban knowledge; owing to their "behavior", these neurons can communicate and perform actions on other components. Urban classes inserted in the hyperciass "process" may be used for building very large models simulating complex urban phenomenons, thus allowing a better understanding of the real phenomenons. As a conclusion, we emphasize the methodological aspects of object-oriented integration for an efficient processing of the urban context, based on prototyping and mixing rules, neurons and processes.

title SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article.

Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components.

Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

title Base de datos de la arquitectura moderna de la ciudad de Maracaibo 1920-1990 [Database of the Modern Architecture of the City of Maracaibo 1920-1990]
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
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.

title Architectural Photogrammetry & Knowledge-Base Systems Record & Redevelopment
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary In redevelopment projects, the purpose of heritage recording is part of an investigative process to achieve understanding about structures so that designers can make the appropriate design decisions. It is desirable to integrate the knowledge of the recording and documentation specialist, who has first-hand knowledge of the building, with the interpretative process of evaluating the building information and making design decisions. New developments in the fields of photogram-metric recording and computer science has led to improved "image understanding". This paper describes research that is the result of exploring the concept of integrating new digital photogram-metric recording processes with an automated expert evaluation tool. The goal of this research is to expedite the acquisition of heritage building information for use by a knowledge-based system capable of providing the designer with building performance evaluations. Photogrammetry records all data as a series of three-dimensional coordinates which make it a natural partner for today's three-dimensional CAD systems. Generating a three-dimensional model of architecturally significant physical forms and details can provide a basis for evaluation, understanding, education, and design. The purpose of knowledge-based systems in construction is to enhance the decision-making process with specialized knowledge and experience. The linkage of CAD databases with knowledge-based systems provides a source of input data, such as a three-dimensional model, significant to a particular problem. This research is a collaborative effort between two groups, the Swiss Federal Institute of Technology in Zurich Switzerland, and the University of Manitoba in Winnipeg, Canada.

title Graphical Knowledge Interfaces: The Extensive and Intensive Useof Precedent Data Bases in Architecture and Urban Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Space syntax' is a family of techniques for the analysis of architectural and urban space which can be used both in research and design mode. This means, for example, that a redevelopment area in an urban context can be researched using space syntax models which can then be turned round and used as the basis for design idea of a 'graphical knowledge interface' (GM) is a further development of this in feeding research into design. It starts from the important role that the analysis and comparison of 'precedents', that is, cases with some similarity of the design problem in hand, often play in design. In a GM, 'precedents' which have already been researched using the space syntax methodology and which are relevant to a particular design problem - say a set of urban areas or a set of housing estates - can be brought into the modelling technique, so that the designer has on hand not simply a space syntax model of the problem in hand but an intelligent 'precedent' in the form of graphical and statistical representations which can be manipulated and interrogated during the design process, in much the same way as discussion of precedent are currently brought into design but with much more complex data and much more powerful theoretical tools. GM can be used as intensive mode, in which many different kinds of data - say on land uses, rents, or crime rates - are added to the model of an area, or in extensive mode where the emphasis is on comparing, say, the structures of a large number of urban areas. The GM will be illustrated through a worked example of a recent major urban design project in which the team has participated.

summary What is the role of CAAD as a tool of architectural form creation ? We used to over-estimate the role of computer as significant factor of design process. In fact it serves only to produce technical documentation and to visualise designed buildings. We usually use CAAD to record ideas, not to create designs. We use it like more complex pencil. But it is unsuitable for conceptual design , with imperceptible influence on idea definition. Its practical usefulnes is limited. I would like to consider and find out reasons of that state, present some conclusions and ideas on computer aided architectural form creation. Many tools were invented to extend posibilities of human body or intellect. Microscop and telescop are extensions of human eye. Which organ is extended by computer (especially by CAAD)? CAAD with high developed function of visualising of the object beeing designed seems to be an extension of architect's imagination. It is beeing used to foresee visual efects, to check designed forms, to see something what we are not able to imagine. It performes the role of electronic modeler. Real model and virtual model - the medium of presentation is diferent but ways of using them are similar . Dislocation of place where we build model is not a big achievement, but potential possbilities of CAAD in modeling are almost unlimited (?). What are special features of CAAD as a modeling tool? First we have to consider what is indispensible when building a model: to embody idea. To do this we need space, substance and tools. In architectural design practice space is a real site with definite climate, neigbourhood, orientation. Substance that we shape is an archiectural form composed of many difrent elements: walls, windows, roof, entry, ... , proportions, rhythm, emotions, impresions... The tool is: our knowledge, imagination, talent, experience, norms, law and drawing equipment. Working with the computer, making virtual model, we have many of mentioned elements given in structure of CAAD program and interpreted by it. But many of them have different character. Making traditional dummy of building we operate on reality which is manually accessible. In case of computer model we operate on information. Space, substance and tool (- program) are informations, data. Human being is not an abstract data processor, but creature that lives non stop in close, direct, sensual contact with nature. By this contact with enviroment collects experiences. Computer can operate on digital data that is optionally selected and given by user, independent upon enviromental conditions. Usually architecture was created on basis of enviroment, climate, gravity. But these do not exist in CAAD programs or exist in the symbolic form. Character of these conditions is not obvious. We can watch demeanour of objects in gravity but it can be also antigravity. In theory of systems everything is considered as a part of biger system. In "virtual" reality (in computer space) we deal with accurences which are reduced to abstract level, free upon terms or connections. We work with our CAAD software using geometric space whithout any other principle.

title Data representations in an integrated architectural design environment
source University of Strathclyde, Dept. of Architecture and Building Science
summary The architectural design process is very complex and involves cross-disciplinary communication among many related fields. Given the further problems arising from the technological advances in building materials and construction methods, an integrated design environment becomes a central design issue. There have been many attempts to analyse and structure the design process as a uniform hierarchical framework. Most of the attempts resulted in a vague and inappropriate outcome due to the lack of understanding of architectural design complexity and inconsistent design data control sequence. A design problem cannot be comprehensively stated because the design problem has a multi-disciplinary nature and the design problem itself evolves as solutions are attempted by the designer. Therefore, an ideal CAAD system should have the capability to accommodate the multi-disciplinary nature of design and should not prescribe or restrict design concepts and design knowledge. A well designed integrated design environment provides more information and invokes creative imagination for each design stage, and therefore creative decision making by the designer can be achieved. This thesis proposes a prototype architectural design environment, Hybrid Integrated Design Environment [HIDE], which aims to integrate all applications for designing a building. Within the object-oriented design environment, a unified data model and a data management system have been implemented to seamlessly connect all applications. Development of the environment needs to consider the fundamental interaction between each module. Devising a data structure that is appropriate to an effective data communication among the various design stages is essential in a totally integrated CAAD system. The suggested unified data model organizes the structure of the design data to keep the design consistent throughout the design and construction process. By means of the unified data model, integrated CAAD systems could represent and exchange design information at a semantic level, i.e. the user’s way of thinking, such as exchanging components and features of a building rather than graphical primitives. In consequence, the unified data model reduces the misunderstandings and communication problems among the multiple disciplines of architectural design. The suggested data management system supports the consistent and straight forward mechanisms for controlling the data representation through the inter-connected modules. It is responsible for creating, maintaining, and viewing a consistent database of the design description. It also helps to perform effective data communication among the various design stages to ensure quality and time saving in the final construction of the building. To support inter-disciplinary communication of design concepts and decisions, the integrating of relevant CAAD tools is essential. In the environment, the integration of CAAD tools has been performed on the basis of how well computerized design tools can assist designers to develop better solutions, enabling them to manipulate and appraise varying solutions quickly and with a minimum of effort in an environment conducive to creative design. A well designed user interface system can also benefit the seamless working environment. The proposed user friendly interface system allows a user to explore the environment in a highly interactive manner. From the development of the early data model to the final design, a user could benefit from the prototypes and methods of the user interface system. The ultimate goal of the prototype environment is to suggest a future design environment which helps the architect to have minimum discontinuity in his creativity and make the design process similar to the natural design process with the help of a set of design assistance modules. A prototype version of HIDE has been implemented and a demonstration of the environment is part of this thesis.

title "To See Ideas" or The Visualizing of Programmatic Data Reading Examples in Architecture and Town Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Whether images are still in the mind, metaphors, sketches or icons, they play a crucial role. They have always been the heuristic pivot around which the process of artefact design organizes itself, particularly in architecture and town-planning. "To see ideas" through computer ideograms is to experiment an interesting and new direction for "pictural approach" supported design. Cognitive psychology emphasizes the important part played by mental images in reasoning, imagination in the working of human intelligence and the construction of mental images as cognitive factors underlying reasoning. It also points out how close computerized objects and mental schemata are. "To reason over a situation is first to remember or build some mental models of this situation; second to make those models work or simulate them in order to observe what would happen in different circumstances and then verify whether they fit the experiment data; third to select the best model, a tool meant to sustain and amplify the elaboration of mental models, which is a spontaneous activity". We introduce our exploration of the direct transmission of mental models through computer ideograms. We study the "operative" and the "expressive" aspects, and this allows us to analyze how some aspects in a field of knowledge are represented by ideograms, schemata, icons, etc. Aid to imagination, reasoning and communication by means of a graphic language must be limited to some figurative relevant aspects of the domain considered; it should not aim at a realistic simulation. Therefore, the important role played by icons and the spatial schematic representation of knowledge is emphasized. Our hypothesis is that an architectural concept does not result from an inductive process, but rather is built to solve problems through the direct representation of ideas with ideograms. An experiment was conducted with a graphic language, a dynamic scenography and actor-objects. The language allows one to build and visualize models from the various domains of knowledge of the object. The dynamic scenography can explore and simulate kinetically those models by means of staging various narrations and visual scenarios. The actor-objects play various and complementary parts in order to make the image explicit and link it with the concept. We distinguish between two parallel levels of reality in computer ideographics: one concerns the model, it represents the visualization of a graphic model at a particular moment and according to a particular representation, the other concerns the ideogram.

title Form and Performance in Intelligent CAAD Systems for Early Stages in Solar Design Building
source Technion, Faculty of Architecture and Town Planing, Haifa
summary Great care should be taken at the initial design stages to determine the principles and solution schemes for climate and energy-conscious buildings. The present study deals with supporting the designer's efforts at the early stages to lay down the appropriate principles for a conceptual and geometric design of energy-preserving buildings, which are also thermally comfortable and adapted to local climatic conditions. For years, especially during the last decade, important data concerning climate-conscious construction has been compiled, but the information has not been utilized by designers, due to its inaccessibility. It is significant, though, that solutions based on this knowledge could be found and assessed at the preliminary design steps. A correct climate-conscious design conceived at the initial stages may guarantee that during later phases of the project's development no problems calling for essential and drastic changes in the basic design will crop up. The meaning of such changes at later stages may require sometimes a redesigning of the entire project. It is vital, therefore, to understand at the pre-conceptual phase, what are the correct climatic-solar design strategies which satisfy the requirements of the local conditions, and enable the attainment of thermal comfort conditions, while consuming the least possible energy. The present study proposes a computer-aided passive solar design system (PASYS) which enables the handling of entire designing process, and its general, conceptual aspects, as well as the preliminary designing steps and their particular, practical aspects. The system is based both on a knowledge base which stores the existing information concerning solar-climatic construction in the form of rules of thumb, and on precise procedural models which enable finding solutions suited to the local climatic conditions. The proposed system is an intelligent CAAD system which equips the designer who is aware of the constraints of climate and energy, with a tool to achieve a better design. PASYS was developed as a universal system to deal with the various activities involved in the initial – pre-conceptual and conceptual - design stages. The system supports the following design activities of each stage of this kind: analysis, synthesis, documentation, assessment and decision making. It is capable of analyzing given conditions, thus helping the designer understand which are the significant preliminary design stages that have a bearing on thermal comfort conditions in a given climate. The system is also capable of proposing solutions corresponding with the particular design phase, and assess their adequacy. These solutions take into account the constraints determined both by the designer and by the system itself, owing to the knowledge base it contains. The system can also document the various solutions that have been found and selected, so that may be further developed at later stages. This documentation is carried out by a graphic interface, developed as part of the system, as well as by an interface devised for existing CAD software. This study highlights the interaction between form and performance. The system is able to assess the performance of a proposed design by considering a given geometry (form), or viceversa, it is able to recommend a solution that can deliver desired and required performances. The study comprises three parts: (a.) Development of the conceptual model of a knowledge based design process. (b.) Further development of the initial stages of the afore mentioned process, including the pre-conceptual and conceptual stages. (c.) Demonstration of the mode of work with the PASYS system. // The first part of the study deals with the definition of the design process, the definition of the various design steps and their characteristics, and the definition of the activities involved in each design step. This part of the work also presents the kinds of knowledge bases affecting the design process, and shows how this knowledge is an inseparable part of the design process. The second part deals with the development of the initial design stages - the pre-conceptual and the conceptual - which are based on knowledge. This part also contains compiled knowledge that is relevant to the design stage, and a knowledge storage and retrieval method that was developed so as to make the knowledge available and accessible on demand. This part further presents precise procedural methods, developed to find solutions adapted to the specific given conditions, and to precisely assess the performance of the proposed solution. A case in point is the module of the SHADING system which enables a precise assessment of the mutual shading of buildings, and an examination of the exposure of the southern elevation to the sun, which is necessary in order to determine the effective solar absorption area in a proposed project in given environment conditions. The third part of the study demonstrates the solar-climatic design process put into action and supported by the system that was developed. This system enables the designer, even at the preliminary design stages, to determine which properties relating to local climatic conditions he will introduce into the building. This important, seemingly natural act, is usually performed during more advanced stages, when it might generate significant changes in the design, at a juncture when changes are hard to make. A PASYS-aided design environment ensures that from the beginning of the designing process, the project will be designed correctly and efficiently as far as energy is concerned.

summary The need for regional styles to exist in architecture has been broadly and long discussed. In general, regionalisms are socially accepted and they should be employed. Discussions usually become more intensified together with the search for inspiration to create new styles in architecture. In Poland Stanislaw Witkiewicz, arts critic and theoretitian, a painter and a writer, created and developed “the Zakopane style” on the turn of the 19th century. This is the only one architectural style focussed on the regional features that has been preserved until nowadays. It referred both to architecture and industrial forms. It was received by the contemporaries with ambivalent attitude, from the uncritical enthusiasm to emotional negation. One side claimed that the style affected the national consciousness and united the nation without the State. According to the other side, “the Zakopane style”, when outside the Podhale region, shocked with its non-conformity to the surroundings. About 1910 there was an attempt to create the style not exactly regional but rather national. The designs referred to neoclassic Old Polish mansion house with a porch supported by columns and high mansard roof. Between 1915 and 1918 projects to rebuild the Polish villages and little towns were thrown open to competition. Afterwards, neatly published project catalogues presented universal, all-Polish type of architecture. In 1918, after I World War and after Poland regained independence, whole housing estates were built in manorial style. At the same time the described sets of competition projects were used together with the new ones, prepared by eg. Polish Hygenic Society (1936). All the project proposals show the all-Polish type of regionalism. Another intensification of discussion concerning the regional style is linked with the post-modernist ideas. Modernism-lacking ornament, cosmopolitan, without any homely features (by the way, he is jolly smart who knows what this “homeliness” is all about) despite its undeniable achievements has been finally faced with crushing criticism. Together with this reaction the search for inspiration in regional features of architecture has been revived. But then there has been a lack of Witkiewicz’s enthusiasm and stubbornness. We deal with constant attempts to solve the problem of creation in regional style. The situation described allows for the statement that there are two forms of regionalism: one on a narrow, territorial and second on the all-Polish scale. No doubt, “the Zakopane style” was the territorial regionalism, and the manorial architecture-the all-Polish one. The condition and quantity of traditional forms are really varied in Poland. For these still existing objects to serve as “model” and inspiration, they have to be examined, classified and made accessible to the designers. The next step is to extract the most distinct features of sub-regions and to popularize the knowledge of these problems. At the Faculty of Architecture of Bialystok Technical University the relative data base concerning the regional architecture is being created on the basis of Microsoft’s ACCESS. It is still another attempt to preserve and uphold the cultural landscape of Poland.

title A run time exchange of component information between CAD and object models: A standard interface
source The Int. Journal of Construction IT 2(2), pp. 37-52
summary Integrated computer aided design could only occur in engineering once CAD systems could represent physical features and components rather than graphical primitives. In most dedicated CAD systems, the knowledge of a complete component exists only for the duration of each drawing command and the data stored in the database is simply a set of graphic primitives. This paper proposes an approach for real time information transfer from and to CAD systems based on a high level object representation of the design drawing. Drawing components are automatically identified and represented in an object hierarchy that reflects the 'part-of' relation between the various components including building spaces. Such hierarchies transfer an industry standard CAD system i.e. AutoCAD, into a high level object oriented system that can communicate with external applications with relative ease.

title Design of a View-Based DSS For Location Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary This paper describes the design of a DSS for locating facility networks. The proposed DSS is based on the principle of dynamic data definitions. The declarative and procedural forms of knowledge involved are identified by a logical analysis of planning tasks. The DSS supports an iterating process of adjusting and evaluating plan options. A flexible and interactive problem solving environment is achieved by means of a user defined set of views that captures both forms of knowledge. Each view describes the system to be planned in terms of a set of variables and attached evaluation procedures. The views are dynamic and linked data structures, so that changes in one view automatically lead to updating all linked views. The DSS supports both the specification of the set of views and its application to solve a specific location problem.

title The Design of Decision Support Systems in Urban and Regional Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Planning methodology over the years, has shifted from situations whereby planners think, plan and design for the people to one whereby both people and planners have become important components of the planning process. Consequently, the important urban planning methodology of the last two decades that utilized mathematical models in the planning process is fast becoming obsolete. The paper argues that model building should move to the creation of urban decision support systems for the planning process through the development of expert systems shells that interfaces existing planning models with the knowledge content of planning and planners. The expert system shells as the set of decision rules for determining how existing supply and demand relationships are applied for modelling land use and transportation would be responsible forguiding the development of appropriate geographical information systems, supporting land use and other models in a coordinated manner, for communicating with these other systems componentsand for guiding interactions between them and the user. Furthermore, decision support systems should be designed to bring the whole of the knowledge base to bear on a problem through a flexible and adaptive solution system that makes explicit use of both the analysts models and the decision makers expert knowledge. It is argued that this understanding leads to the development of three crucial issues for the design of decision support systems in urban and regional planning;namely the development of user friendly integrated urban land-use transportation models, the development of expert geographical information systems and the development of expert systemshells for many of the routine tasks planners deal with.

title Assesing Strategy Questionnaire for Architectural Styles of Designing (ASQ-FASD)
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary In this paper the first results will be discussed that were obtained by the Assessing Strategy Questionnaire For Architectural Styles of Designing (ASQ-FASD). This questionnaire was developed specifically for the assessment of architectural design strategies. The construction of the questionnaire will be discussed in light of previous protocol research on strategic styles of designing. With this questionnaire, we developed a tool to assess an architects design strategy in a faster, easier and more reliable way than used to be the case with conventional protocol studies and other knowledge eliciting techniques like Card Sorting, and Repertory Grid. This questionnairewas submitted in a pilot study to 10 experienced Dutch architects. R.esults show that architects do indeed have preferences for different design situations. Moreover results indicate that they havea preference with respect to their responses within such specific situations. Though the generalizability coefficient was calculated for no more than 10 architects with a value of .57 (generalizing across situations), we feel that this is reason enough to assume that the questionnaire can be used to assess design strategies of architects. These results will be discussed with respect to the development of new design and decision support tools. The fact that designers have preferences for specific design problems and that they respond differently should be considered in the implementation of user interfaces and data base technology where possible.

title Communicative Acts in Cooperative Architectural Design Environments
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The purpose of this paper is to present a scheme, that can be used to support the communication process in cooperative design. Computational aids for design have largely been for a designerworking by himself/herself. These aids have also been supplemented by the widespread use of artificial intelligence approaches. However, design is so complex, and very rarely acted upon by a single designer but many more working towards the same aim. This involves a new paradigm in which designers need to cooperate with each other using a computational medium. A protocol analysis in cooperative design has been carried out and technological support has been proposed.Cooperative design becomes an important paradigm for the next generation of intelligent computer aided design systems. It will be conducted in many forms among several designers and willrequire the support of advanced communication facilities beyond the "passive" transmission of data and messages. Technological advances in communication networks have opened up new ways for cooperative design interaction across several processes of cooperation among designers, designers and computer aided design systems, computer aided design systems and knowledge based systems, and knowledge based systems themselves. In cooperative design environments, aunit of communication among designers is the transfer of a message from one designer (a sender) to another (a receiver). The aim of such communication is to provide the receiver with some information or to have the receiver take certain actions. Inspired by the speech act theory, a branch of the philosophy of language and linguistics, such a unit is called a communicative act. By analogy to architectural design, a communicative act is a performing act in designers communication.

doi https://doi.org/10.52842/conf.acadia.1994.005
summary The process of architectural design aims to define a physical form that will achieve certain functional and behavioral objectives in a particular context. It comprises three distinct, but highly interrelated, operations: (1) Definition of the desired objectives; (2) production of alternative design solutions; (3) evaluation of the expected performances of the solutions and their comparison to the predefined objectives. Design can be viewed as a process of search for a solution that satisfies stated needs, while at the same time adapting the needs to the opportunities and limitations inherent in the emerging solution. // Computational techniques were developed to assist each one of the three operations, with varying degrees of success. We propose to integrate all three operations into one whole, by developing a computational model that will facilitate smooth transition from one operation to another. The role of computers in supporting this model will include providing a knowledge base of prototypical design objectives and solutions, storing project-specific design goals and solutions, and predicting their expected performances. This paper discusses the rationale and background for developing such a knowledge-based design system, and presents the parameters for implementing it as a computational tool to support architectural design. Examples from a prototype implementation serve to illustrate the discussion.

title A Proposal for a Framework for Business Re-engineering in Design and Realization of Artificial Environments
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary According to the Top-Down design process', this paper gives a generic and qualitative description of a Concurrent Engineering Environment, that should support the problem solving procedure in town planning and architecture in a modern quality oriented society. A system that is based on the principal of democracy might guarantee the preservation of quality in the projection and realization of artificial environments. This environment can be seen as a part of the today often discussed "digital democracy", which practically is based on a infrastructure of computers, interfaces, software systems, a network, databases and a data presentation, that is able to comprise the expectations of professionals involved in the architecture and town planning process. The paper will discuss what the role of the designer and coordinator of this computer environment looks like,in order to design, plan, build and coordinate activities for the realization of this Concurrent Environment and how several software engineers work concurrently to develop tools that guarantee a modular integration. The backbone of this environment is the definition and use of standards for data exchange. Basically those standards are derived from two domains: artifacts will be described in a product model data, while natural resources are described in spatial data. Town planning has to integrate both models. It will be discussed briefly how far the data modelling language EXPRESS of part 11 of the ISO 10303 (Express Language Reference Manual) might be useful to model GIS related problems. An example will describe how a scenario of activities, from registration of real world data to recognition of requirements of society, the definition of development plans through design(competition), lawfulness checking and construction until demolition should look like.

title What Conceptual Modelling Is and Isn´t
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary It is generally agreed that conceptual modelling is an important activity in the development of knowledge based systems. The availability of an adequate conceptual model is of vital interest notonly for the design and implementation of knowledge based systems, but also for their validation, modification, maintenance and enhancement. In order to be able to develop adequate conceptualmodels a theory about the nature of knowledge is required and, in line with this theory, a methodology to reconstruct the meaning of concepts. Additionally, techniques have to be selected which enable the modelling, representation, validation and simulation of reconstructed concepts. In the development of knowledge based systems often techniques are used which are not very wellsuited to the reconstruction and representation of the concepts of an application area. The selection of a technique is not motivated by an explicitly formulated theory, but by the representation formalisms applied within the software used for the implementation of knowledge based systems. This often leads to inadequate conceptual models and consequently poorly functional and hardly maintainable systems, mainly because the representation of concepts is adapted to the limitations of the applied representation formalism. In this paper we explain how the conceptual modelling activity isusually tackled in thedevelopment of knowledge based systems and what the related problems are.
