title An electronic design assistance tool for case-based representation of designs
source Automation in Construction 6 (4) (1997) pp. 265-274
summary In precedent based design, solutions to problems are developed by drawing from an understanding of landmark designs. Many of the key design operations in this mode are similar to the functionalities present in case-based reasoning systems: case matching, case adapting, and case representation. It is clear that a rich case-base, encoding all major product types in a design domain would be the centerpiece of such an approach. EDAT (Electronic Design Assistance Tool) is intended to assist in precedent based design in the studio with the potential of expansion into the office setting. EDAT has been designed using object oriented system development methods. EDAT was used in a design studio at Carnegie Mellon University, during Spring 1996.

title Impact-Analysis of Urban Design Realtime impact-analysis models for urban designers
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary The past five years Prof Dr Jr T.M. de Jong, professor in environmental planning and sustainability at the Technical University of Delft, has developed a theoretical foundation for the analysis of urban design on the ecological, technical, economical, cultural and political impacts of morphologic interventions on different levels of scale. From september 1994 Jr AJ. Boelen (Urban Design Scientist and Knowledge Engineer) started a research project at the same university to further explore the possibilities of these theories and to develop impact evaluation models for urban design and development with the theoretical work of De Jong as a starting point. The paper discusses the development of a design and decision support system based on these theories. For the development of this system, techniques like object-orientation, genetic algorithms and knowledge engineering are used. The user interface, the relation between the real world, paper maps and virtual maps and the presentation of design-interventions and impacts caused by the interventions are important issues. The development-process is an interactive step by step process. It consists of the making of a prototype of the system, testing the theory and hypothe-sisses the system is based on, by applying tests end adjusting the theory and hypothesisses where needed. Eventually the system must be able to act as an integrator of many different models already developed or still to be developed. The structure of the system will allow easy future expansion and adjustment to changing insights. The logic used to develop the basic theory on which this system is founded makes it possible to even introduce and maintain rather subjective aspects like quality or appraisal as impacts that can be evaluated. In a previously developed system "Momentum" this was proved to work effectively for the national level. In this project we will - amongst other things - try to prove the effectiveness of impact-evaluation for other levels of scale.

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 Criteria for the Selection of Conceptual Modelling Languages for Knowledge Based Systems
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary In recent years knowledge is increasingly recognised as a critical production factor for organisations. Performance of activities such as designing, diagnosing, advising and decision making, depend on the availability and accessibility of knowledge. However, the increasing volume and complexity of knowledge endangers its availability and accessibility. By their knowledge processing competence, knowledge based systems containing a structured and explicit representation of knowledge, are expected to solve this problem. In the realisation of a knowledge based system, the phase in which a knowledge model is reconstructed through a conceptual language, is essential. Because the knowledge model has to be an adequate reflection of real-world knowledge, the conceptual language should not only offer sufficient expressiveness for unambiguous knowledge representation, but also provide facilities to validate knowledge on correctness, completeness and consistency. Furthermore, the language should supply facilities to be processed by a computer. This paper discusses fundamental criteria to select a conceptual language for modelling the knowledge of a knowledge based system. It substantiates the claim that the selection depends on the nature of the knowledge in the application domain. By analysing the nature of knowledge using the theory of functional object-types, a framework to compare, evaluate and select a conceptual language is presented. To illustrate the selection process, the paper describes the choice of a conceptual language of a knowledge based system for checking office buildings on fire-safety demands. In this application domain, the language formed by decision tables has been selected to develop the conceptual model. The paper provides an in-depth motivation why decision tables form the best language to model the knowledge in this case.

title ADELINE, an Integrated Approach to Lighting Simulation
source Proceedings of Right Light 4, 4th European Conference on Energy-Efficient Lighting, pp.99-103
summary The use of daylighting and artificial lighting simulation programs to calculate complex systems and models in the design practice often is impeded by the fact that the operation of these programs, especially the model input, is extremely complicated and time-consuming. Programs that are easier to use generally do not show the calculation capabilities required in practice. A second obstacle arises as the lighting calculations often do not allow any statements regarding the interactions with the energetic and thermal building performance. Both problems are mainly due to a lacking integration of the design tools of other building design practitioners as well as due to insufficient user interfaces. The program package ADELINE (Advanced Daylight and Electric Lighting Integrated New Environment) being available since May 1996 as completely revised version 2.0 presents a promising approach to solve these problems. This contribution describes the approaches and methods used within the international project IEA Task 21 for a further development of the ADELINE system. Aim of this work is a further improvement of user interfaces based on the inclusion of new dialogs and on a portation of the program system from MS-DOS to the Windows NT platform. Additional focus is laid on the use of recent developments in the field of information technology and experiences gained in other projects on integrated building design systems, like for example EU-COMBINE, in a pragmatical way. An integrated building design system with open standardized interfaces is to be achieved inter alia by using ISOSTEP formats, database technologies and a consequent, object-oriented design.

title A World of Data: An Animated Construction Information System as a Virtual Hypergraphic Environment
doi https://doi.org/10.52842/conf.acadia.1996.267
source Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 267-274
summary This paper describes research on an animated construction information system organized as a hypergraphic virtual environment. The user enters this environment to interact with the information it contains. A matrix of cubes sits as the gateway to an array of data chambers that give this information its virtual form. A mouse click on one of these cubes leads to a three-dimensional interface that is a simulation of the object to be constructed. Reflective-transparent panels surround the simulation and display two-dimensional projections of its pieces. These panels capture projections of slices through the pieces of the object represented by the simulation. Below the zero plane are slices of floor framing, foundation, excavation, utilities, and soil conditions. Above are ceilings, framing, and roofing. To the sides are finishes, wall framing, fixtures, and elevations. This immersive virtual environment extends as an array of data chambers partitioned by the suspended reflective-transparent panels. Pathways around these partitions lead to secondary chambers that contain sub-simulations of the plumbing, electrical, and HVAC systems. Design-team members access these chambers to coordinate the document's development, review progress, and make changes to the information system. The result is a WORLD of data where graphic information defines both space and time. This breaks with the notion of a construction document as an object-of-exchange and suggests a new focus for the use of computers in the design and construction process.

title An Outline of the Requirements for a Computer-Supported Collaborative Design System
source Open House International, vol 21, no 1, March 1996
summary Computer-Aided Architectural Design (CAAD) systems have adequately satisfied several needs so far. They have dramatically improved the accuracy and consistency of working drawings, enabled designers to visualize their design ideas in three-dimensions, allowed the analysis of designs through data exchange and integrated databases, and even allowed the designers to evaluate (and in some cases generate) designs based on comparisons to previous cases and/or the formalization of grammars. Yet, there is a consensus that CAAD systems have not yet achieved their full potential. First, most systems employ a single-user approach to solving architectural problems which fails to grapple with the fact that most design work is done through teamwork. Second, current systems still can not support early design stages which involve client briefing, data collection, building program formulation, and schematic design generation. This paper seeks to study remedies to both of the afore-mentioned limitations through focusing on the fundamental dialectic and collaborative nature of what is called designing: a concerned social activity that proceeds by creating architectural elements to address a set of requirements and their re-thinking as a result of architectural conjecture. To investigate this relationship, it is proposed to build a computer-supported collaborative design environment using the tools of conceptual modeling, object-oriented algorithms, and distributed agents. Based on findings regarding the role of artifacts in collaborative design and a literature survey, this paper concludes with an outline of the requirements for the above system.

title A Design System for Concurrent Reuse of Architectural Data
doi https://doi.org/10.52842/conf.caadria.1996.163
source CAADRIA ‘96 [Proceedings of The First Conference on Computer Aided Architectural Design Research in Asia / ISBN 9627-75-703-9] Hong Kong (Hong Kong) 25-27 April 1996, pp. 163-172
summary This paper describes a design system which supports the concurrent re-use of existing design information by means of an object-oriented database system. The system manages component versioning within a flexible design environment which is to be used by a design team working on an evolving, complex design. A database of prototype designs has been built with a database system that supports versioning. The basic database operations are then extended with the routines that support inter-designer communication. The database system with these extensions produces a design environment in which designers using partitioned design databases holding multiple design component versions, may concurrently develop new designs. In addition, an expert system shell has been incorporated to deal with design evaluation processes. In this paper, the authors investigate the mechanisms by which existing design versions may be represented, combined and edited to provide new designs.

title Gentrification Waves in the Inner-City of Milan - A multi agent / cellular automata model based on Smith's Rent Gap theory
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 187-201
summary The aim of this paper is to investigate the gentrification process by applying an urban spatial model of gentrification, based on Smith's (1979; 1987; 1996) Rent Gap theory. The rich sociological literature on the topic mainly assumes gentrification to be a cultural phenomenon, namely the result of a demand pressure of the suburban middle and upper class, willing to return to the city (Ley, 1980; Lipton, 1977, May, 1996). Little attempt has been made to investigate and build a sound economic explanation on the causes of the process. The Rent Gap theory (RGT) of Neil Smith still represents an important contribution in this direction. At the heart of Smith's argument there is the assumption that gentrification takes place because capitals return to the inner city, creating opportunities for residential relocation and profit. This paper illustrates a dynamic model of Smith's theory through a multi-agent/ cellular automata system approach (Batty, 2005) developed on a Netlogo platform. A set of behavioural rules for each agent involved (homeowner, landlord, tenant and developer, and the passive 'dwelling' agent with their rent and level of decay) are formalised. The simulations show the surge of neighbouring degradation or renovation and population turn over, starting with different initial states of decay and estate rent values. Consistent with a Self Organized Criticality approach, the model shows that non linear interactions at local level may produce different configurations of the system at macro level. This paper represents a further development of a previous version of the model (Diappi, Bolchi, 2005). The model proposed here includes some more realistic factors inspired by the features of housing market dynamics in the city of Milan. It includes the shape of the potential rent according to city form and functions, the subdivision in areal submarkets according to the current rents, and their maintenance levels. The model has a more realistic visualisation of the city and its form, and is able to show the different dynamics of the emergent neighbourhoods in the last ten years in Milan.

title Matching the Knowledge Needs of Trade and Industry: Advanced and Operational Knowledge Based Systems
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary Complex tasks that are being performed in trade and industry such as diagnosis, engineering and planning, increasingly require rapid and easy access to large amounts of complicated knowledge. To cope with these demands on trade and industry, advanced automated support for managing knowledge seems to be needed. Knowledge based systems are claimed to match these needs. However, to deal with the vast volume and complexity of knowledge through knowledge based systems, preconditions at three computer systems levels should be fulfilled. At the first level, called the knowledge level, the development of knowledge based systems requires a well-elaborated theory of the nature of knowledge that helps to get a clear and consistent definition of knowledge. By providing guidelines for selecting and developing methodologies and for organising the mathematical functions underlying knowledge representation formalisms, such a definition significantly advances the process of knowledge engineering. Here, we present the theory of functional object-types as a theory of the nature of knowledge. At the second level, called the symbol level, the representation formalisms used must be compatible with the chosen theory of the nature of knowledge. The representation formalisms also have to be interpretable as propositions representing knowledge, so that their knowledge level import can be assessed. Furthermore, knowledge representation formalisms have to play a causal role in the intelligent behaviour of the knowledge based system. At the third level, called the systems level, a knowledge based system should be equipped with facilities that enable an effective management of the representation formalisms used. Yet other system facilities are needed to allow the knowledge base to communicate with existing computer systems used in the daily practice of trade and industry, for instance Database Management Systems, Geographical Information Systems and Computer Aided Design Systems. It should be taken into account that these systems may run in different networks and on different operating systems. A real-world knowledge based system that operates in the field of soil contamination exemplifies the development of an advanced and operational knowledge-based system that complies with the preconditions at each computer systems level.

summary This paper introduces the concept, structure, components, and application results of "SEMPER", an active, multi-aspect computational tool for comprehensive simulation-based design assistance. Specifically, SEMPER seeks to meet the following requirements: a) a methodologically consistent (first- principles-based) performance modeling approach through the entire building design and engineering process; b) seamless and dynamic communication between the simulation models and an object- oriented space-based design environment using the structural homology of various domain representations; and c) "preference-based" performance-to-design mapping technology (bidirectional inference). SEMPER involves the integrated computational modeling of heat transfer, air flow, HVAC system performance, thermal comfort, daylighting and electrical lighting, acoustics, and life-cycle assessment.

summary This paper focuses on the development of an integrated information model suitable for a knowledge-based system to automate the building design process including code compliance checking. The development of such a data model is based on object-oriented knowledge representation techniques in which building entities and relationships are represented by objects and attributes through appropriate frame-based forms, whereas rule-based representations are used to describe the knowledge contained in building regulations. The proposed approach integrates all relevant information among different disciplines such as architecture, engineering, and building regulations in an object-oriented model capable of exchanging all the information by means of a common database. The implementation of a prototype system is also described.

title A STEP Towards a Computer based Integrated Building Design System
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary Building design is a multi-actor and multi-task process. In a design project architects, engineers and other specialists need to exchange information in order to produce a coherent design. These design participants often have different views of the design from their own perspectives. The aim of an integrated building design system is to develop a building data model that integrates all views so that building information can be exchanged in electronic form between the designers and also throughout various design stages. This paper introduces an integrated building design system developed as part of the European project, Computer Models for the Building Industry in Europe. It concentrates on the development of the Data Exchange System which is a central data repository implemented using an object oriented database and ISO STEP technology and it is able to support concurrent engineering, versioning, history tracing and other data transaction management

title The Use of An Interactive Animation Viewer in Presenting Architectural Design
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary This paper analyzes the use of a 31) hypermedia system in architectural presentation. It first reviews the current process of using computer animation in architectural presentation and identifies problems in the current process. The research assumes that a new approach using the hyper-model environment and animation together would provide a better environment for presenting architectural animation. An interactive animation viewer is designed and developed using the new approach. A sample architectural animation is presented using a tape-recorded animation player, a normal animation player, the interactive animation viewer, and a real-time animation player. The analysis of the result is made by a comparison in terms of image quality, speed, user interactions, object hyperlinkage, scene complexity, and information transmission on using different systems in presenting the same material. A conclusion is drawn to show the advantages of using the new approach. Limitations on using the new approach are identified too.

summary We often speak of changes in design process due to an application of computers. But in my opinion we more often rather speak of lack of changes. Lets hope that some day we will be able to witness full integrity and compatibility of design process and tools applied in it. Quite possible such an integrity may occur in the cyberspace. Nevertheless before that could happen some changes within the teaching methods at faculties of architecture, where despite great numbers of computer equipment used, the students are still being taught as in the XIX century. In terms of achieved results it proves ineffective because application of chalk and blackboard only will always loose to new media, which allow visual perception of dinosaurs in Jurassic Park. Our civilisation is the iconographic one. And that is why teaching methods are about to change. An application of computer as simply a slide projector seems to be way too expensive. New media demands new process and new process demands new media. Lets hope that could be achieved in cyberspace as being a combination of: classic ways of teaching, hypertext, multimedia, virtual reality and a new teaching methodology (as used in Berlitz English School - full brainwash). At our faculty several years ago we experimentally undertook and applied an Integrated Design Teaching Method. A student during design process of an object simultaneously learnt all aspects and functions of the object being designing i.e.: its structure, piping and wiring, material cost and even historic evolution of its form and function. Unfortunately that concept was too extravagant as for the seventies in our reality. At present due to wide implementation of new media and tools in design process we come to consider reimplementation of IDTM again.

title An integrated system for computer-aided design and construction of reinforced concrete buildings using modular forms
source Automation in Construction 5 (4) (1996) pp. 323-341
summary The study reported in this paper investigates the feasibility of automating the on-site construction of reinforced concrete residential buildings. The basic construction tasks are identified, analyzed and modified with a view towards potential for automation. Emphasis is placed on developing modular forms that facilitate automation. The majority of work in the field of construction robotics has focused on the adaptation of existing industrial robots to automate traditional construction processes. This paper outlines a computer-aided construction system approach specially suited for integrating design and implementation by on-site robots. A Computer-Integrated Construction (CIC) system, similar to CIM, is developed that includes a CIC data-base, a construction design system, a construction production/process planning system, and a robotics execution system. This approach is intended to minimize the redesign effort as well as the need for on-site manual work.
