title	Design Tool Integration: Model Flexibility for the Building Profession
source	Proceedings of Building Systems Automation - Integration, University of Wisconsin-Madison
summary	The development of ICAtect, as discussed in the Building Systems Automation and Integration Symposium of 1991, provides a way of integrating simulation tools through a common building model. However, ICAtect is only a small step towards the ultimate goal of total integration and automation of the building design process. In this paper we investigate the next steps on the path toward integration. We examine how models structured to capture the physical attributes of the building, as required by simulation tools, can be used to converse with knowledge-based systems. We consider the types of mappings that occur in the often different views of a building held by these two classes of design tools. This leads us to examine the need for multiple views of a common building model. We then extend our analysis from the views required by simulation and knowledge-based systems, to those required by different segments of the building profession (e.g. architects, engineers, developers, etc.) to converse with such an integrated system. This indicates a need to provide a flexible method of accessing data in the common building model to facilitate use by different building professionals with varying specialities and levels of expertise.

title	A toolset for navigation in virtual environments
source	Proceedings of the ACM User Interface Software and Technology, pp.157-165
summary	Maintaining knowledge of current position and orientation is frequently a problem for people in virtual environments. In this paper we present a toolset of techniques based on principles of navigation derived from real world analogs. We include a discussion of human and avian navigation behaviors and show how knowledge about them were used to design our tools. We also summarize an informal study we performed to determine how our tools influenced the subjects' navigation behavior. We conclude that principles extracted from real world navigation aids such as maps can be seen to apply in virtual environments.

title	Knowledge and data modelling in cad/cam applications
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Modelling knowledge and data in CAD/CAM applications is complex because different goals and contexts have to be taken into account. This complexity makes particular demands upon representation formalisms. Today many modelling tools are based on record structures. By analyzing the requirements for a product model of a portal structure in steel, this paper shows that in many situations record structures are not well suited as a representation formalism for storing knowledge and data in CAD/CAM applications. This is illustrated by performing a knowledge-level analysis of the knowledge and data generated in the design and manufacturing process of a portal structure in steel.

title	Integrated Design and Sustainable Building
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In the international student-project "European Environmental Campus 91 TU Delft Dordrecht" 20 students from 13 European countries worked in september 1991, during three weeks on "EcologicalSketches for the Island of Dordrecht". They worked on four different scales: the region isle of Dordt / the district Stadspolders / the neighbourhood I the house and the block. The environmentaltheme's Energy, Water, Traffic & Noise, Landscape & Soil were together with spatial analyses combined with the different scales. This combination was organised following the scheme mentioned below. The characters stand for the students. During the first period they worked in research groups, during the last period more in design groups. For instance: student L works in the beginning with the students B, G and Q in the research group water. In the last period sheworks with K, M, N and 0 in the design group Neighbourhood. Those students worked earlier in the other research-groups and contribute now in the design-group their thematic environmental knowledge. The results were presented to the Dordrecht council, officials and press. In the next project in september and october 1993 we started earlier with the design groups. Ten Dutch and ten "Erasmus" students worked for six weeks on proposals for the Vinex location Wateringenthe Hague. Each morning they worked in the research groups each afternoon in the design groups. The research groups used the EcoDesign Tools, small applications in Excel on Apple Macintoshto quantify the environmental pressure.

title	Modular building models
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	The development and implementation of a modular building model appropriate for computer aided design is described. The limitations of a unified building model with regard to concurrence and complexity in design is discussed. Current research suggests that to model real-world complexity, one must trade centralized control for autonomy. In this paper we develop a modular approach to building modelling that is based on object-oriented autonomy and makes it possible to define these models in a distributed concurrent manner. Such a modular and autonomous implementation brings inherent uncertainty and conflict which cannot be determined a priori.

title	Generative Modelling and Electronic Lego
doi	https://doi.org/10.52842/conf.ecaade.1993.x.q8a
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	This paper shows work exemplifying the further extent of computer capabilities in the field of design. The work stems from a belief that for computers to be used effectively within the architectural profession their utility must stretch far beyond the process of description of geometric data, but be incorporated in the fundamental roots of design: that of conceptual design. Computers can be used to access the knowledge we have and then formulate this knowledge into a working language of design. Computers can be used to generate space and form in accordance with any relationship the designer may choose to set. This allows them to be used from the very conception of design. It is only by working from the very beginning, the very basis of the design of a building that we can fully develop the integration of computers in the construction industry. The work undertaken sets out primarily to explore one of the ways computers could be used in the field of architectural design. In recognition that an important byproduct of any design search is the enhanced understanding of the problem itself, the work was directed towards a particular project. This allowed each stage of thought to be to be considered as it arose and subsequently incorporated into the design model. The work does not attempt to automise the design process but simply tries to explore some of the opportunities offered by computers and see if they can be easily incorporated into the design process offering design solutions that may not otherwise have been considered. The exploration resulted in a simple design process model that incorporates the more accessible and useful aspects of computer technology.

title	The Future of CAAD Education

source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	The field of Computer-Aided Architectural Design (CAAD) is composed of two main threads of development, Academic and Professional, and can be described in three decades, which correspond roughly with three generations of computer systems. This paper presents a brief description of the entire period of school- and practice-based research and development on the applications of computers in Architectural design, and shows how these efforts have and have not been relevant to students' future experiences. Educators must take a fresh look at their current courses and research programs to make sure that they are relevant in the rapidly changing world of professional practice. With limited human and financial resources at most institutions, it is critical to make the best possible choices for the immediate and long-term benefit of today's students. While it is not appropriate for Schools of Architecture to operate strictly at the behest of the profession, we must prepare our students for the world in which they will practice. Therefore, I believe that it is important for the faculty at each School to consider the following questions: (-) Are our students prepared to enter realistic positions as soon as they graduate? (-) Do they have the background necessary to use computers effectively in the future? (-) Do our research efforts have results that designers are likely to use today or any time soon to make better buildings or to make buildings better?

title	Spatial Perception in Virtual Environments: Evaluating an Architectural Application
source	IEEE Virtual Reality Annual International Symposium, 1993, Seattle
summary	Over the last several years, professionals from many different fields have come to the Human Interface Technology Laboratory (H.I.T.L) to discover and learn about virtual environments. In general, they are impressed by their experiences and express the tremendous potential the tool has in their respective fields. But the potentials are always projected far in the future, and the tool remains just a concept. This is justifiable because the quality of the visual experience is so much less than what people are used to seeing; high definition television, breathtaking special cinematographic effects and photorealistic computer renderings. Instead, the models in virtual environments are very simple looking; they are made of small spaces, filled with simple or abstract looking objects of little color distinctions as seen through displays of noticeably low resolution and at an update rate which leaves much to be desired. Clearly, for most applications, the requirements of precision have not been met yet with virtual interfaces as they exist today. However, there are a few domains where the relatively low level of the technology could be perfectly appropriate. In general, these are applications which require that the information be presented in symbolic or representational form. Having studied architecture, I knew that there are moments during the early part of the design process when conceptual decisions are made which require precisely the simple and representative nature available in existing virtual environments.

title	Design support via simulation of building and plant thermal interaction
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Design decision support related to building energy consumption and/or indoor climate should be based on an integral approach to the environment, the building, heating, ventilating and air-conditioning (HVAC) system, and the occupants. The tools to achieve this are now available in the form of computer simulation systems which treat the building and plant as an integrated dynamic system. Although its potentials reach beyond the area of Computer Aided Building Design, the paper describes building and plant energy simulation within the context of CABD, design decision support and design evaluation. Currently, computer simulation is only used indirectly as a design decision support mechanism; that is, its power is not delivered very efficiently to the design profession. This paper suggests some future research directions. These are aimed at providing a mechanism to overcome this problem by developing an intelligent front end' which bridges the gap between sophisticated computer simulation tools and the design profession.

summary	Since its invention millenia ago, paper has served as one of our primary communications media. Its inherent physical properties make it easy to use, transport, and store, and cheap to manufacture. Despite these advantages, paper remains a second class citizen in the electronic world In this paper, we present a new technology for bridging the paper and the electronic worlds. In the new technology, the user interface moves beyond the workstation and onto paper itself. We describe paper user interface technology and its, implementation in a particular system called XAX.

title	PARADISE: An Intelligent CAD System architecture
source	The Int. Journal of Construction IT 1(3), pp.1-24
summary	This paper presents the architecture of an intelligent CAD system called PARADISE. The motivation is in addressing the lack in architectural computing that has to do with intelligent assistance of design at the early stages. A schema for representing and integrating design knowledge and graphical data called the Design Model (DM) is presented. Following which, work done in developing the CAD-based front end of PARADISE called the graphic subsystem (PGS) is described. The emphasis is at providing tools which facilitate the creation and manipulation of form and spaces at early design stages. We then describe the functionalities of our geometric reasoner (PGS) is described. The geometric reasoner is responsible for all reasoning between the syntax of design drawings and its related semantics. We highlight, in particular, the reasoning of implicit spaces.

title	Recognizing Emergent Subshapes in Design Problem Solving: A Connectionist Investigation
doi	https://doi.org/10.52842/conf.acadia.1993.131
source	Education and Practice: The Critical Interface [ACADIA Conference Proceedings / ISBN 1-880250-02-0] Texas (Texas / USA) 1993, pp. 131-139
summary	Human problem-solving behavior has been modelled as a search through the space as defined as problem states, within which earlier states move to subsequent ones by applying rules in the human mind until the goal state is found. This cognitive model of problem-solving has been broadly accepted and has become dominant in both cognitive psychology and artificial intelligence (AI). In the field of computeraided architectural design (CAAD), search models are also widely used for solving design problems, although various foci of design knowledge are differently represented by shape grammars, graphs, and knowledge-based systems using predicate logic for different purports. In design search, design evolves from one state to another by exhaustively or heuristically applying proper rules. Each rule application involves, first, pattern-matching the antecedent of a rule to the current state and, second, transforming the matched portion of that state into the consequence of the rule. However pattern-matching techniques of current CAAD systems are still limited. In current CAAD systems, only those two squares can be dealt with by patternmatching for further development. However, a human designer can effortlessly recognize not only those two but other emergent subshapes, for example a smaller square in the middle where the two squares overlap and two L-shapes in the corners. Therefore a human designer can thoroughly deliberate all these alternatives before making a decision. In other words, human designer is capable of restructuring shapes in terms of emergent subshapes in any step of designing.

title	Creativity and design as exploration
source	J.S. Gero and M. L. Maher (eds), Modelling Creativity and Knowledge-Based Creative Design, Lawrence Erlbaum Associates, pp. 139-175
summary	This paper considers the problem of creative design, and in particular the role of a priori knowledge or "prototypes" in the design process. A design problem is characterised as one in which both the objectives and the means available for achieving these objectives are (of necessity) initially only poorly defined. Some observations concerning the nature of design process based on this characterisation are presented, and a model of the design process as a knowledge-based exploration task described. The role of prototypes in organising this knowledge is examined, and the widely accepted view that prototypes can form the principle source of knowledge for creativity in design is challenged. In a final section we outline the structural principles of a representation scheme which aims to overcome of these difficulties and describe a design support system which uses this scheme to support the design process.

title	A functional approach to realizing decision support systems in technical regulation management for design and construction
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Technical building standards defining the quality of buildings, building products, building materials and building processes aim to provide acceptable levels of safety, health, usefulness and energy consumption. However, the logical consistency between these goals and the set of regulations produced to achieve them is often hard to identify. Not only the large quantities of highly complex and frequently changing building regulations to be met, but also the variety of user demands and the steadily increasing technical information on (new) materials, products and buildings have produced a very complex set of knowledge and data that should be taken into account when handling technical building regulations. Integrating knowledge technology and database technology is an important step towards managing the complexity of technical regulations. Generally, two strategies can be followed to integrate knowledge and database technology. The main emphasis of the first strategy is on transferring data structures and processing techniques from one field of research to another. The second approach is concerned exclusively with the semantic structure of what is contained in the data-based or knowledge-based system. The aim of this paper is to show that the second or knowledge-level approach, in particular the theory of functional classifications, is more fundamental and more fruitful. It permits a goal-directed rationalized strategy towards analysis, use and application of regulations. Therefore, it enables the reconstruction of (deep) models of regulations, objects and of users accounting for the flexibility and dynamics that are responsible for the complexity of technical regulations. Finally, at the systems level, the theory supports an effective development of a new class of rational Decision Support Systems (DSS), which should reduce the complexity of technical regulations and restore the logical consistency between the goals of technical regulations and the technical regulations themselves.

source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 455-470
summary	Design is rarely an activity that is commenced and completed by an individual The more common design environment is one in which teams of designers work together towards a final solution. In this paper we consider issues involved in the development of computer-based design environments in which teams of design professionals can collaborate, focusing on the need for visual and underlying representations which can support multiple interpretations. We consider the environment as providing a shared workspace which facilitates both communication and progression of design ideas, concepts, and drawings. In the environment presented here, the shared workspace has two foci: the workspace that designers see and interact with, and the workspace that provides an underlying computer-based representation for persistent memory. The emphasis is on providing representations that support emergence that occurs during collaboration.

summary	In the evening reception held at the Mies Van der Rohe's German Pavilion, Gabriel Ferrater, Rector of Universitat Politecnica de Catalunya, challenged the participants of the ECAADE 92 conference that despite all the advances in CAD techniques, none of the many wonderful buildings that had been built in Barcelona was 'designed' on computer. To researchers in the field of design and CAD research, the challenge went deeper than designing and architecture. It questions the very essence of CAD methodology and pedagogy.

title	Modeling the structure of the flow experience
source	INFORMS Marketing Science and the Internet Mini-Conference, MIT
summary	The flow construct (Csikszentmihalyi 1977) has recently been proposed by Hoffman and Novak (1996) as essential to understanding consumer navigation behavior in online environments such as the World Wide Web. Previous researchers (e.g. Csikszentmihalyi 1990; Ghani, Supnick and Rooney 1991; Trevino and Webster 1992; Webster, Trevino and Ryan 1993) have noted that flow is a useful construct for describing more general human-computer interactions. Hoffman and Novak define flow as the state occurring during network navigation which is: 1) characterized by a seamless sequence of responses facilitated by machine interactivity, 2) intrinsically enjoyable, 3) accompanied by a loss of self-consciousness, and 4) selfreinforcing." To experience flow while engaged in an activity, consumers must perceive a balance between their skills and the challenges of the activity, and both their skills and challenges must be above a critical threshold. Hoffman and Novak (1996) propose that flow has a number of positive consequences from a marketing perspective, including increased consumer learning, exploratory behavior, and positive affect."

title	An Approach to Automated Scoring of Architectural Designs
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 215-224
summary	An automated approach to scoring architectural designs of building sites was devised. Design drawings were represented in the computer as a database consisting of a series of objects and their locations and relationships to other objects. Designs were automatically scored by: (a) determining whether or not certain basic requirements were met (such as parking, handicapped access, and building within site boundaries) and (b) determining the extent to which the drawings met criteria of efficient site design. The drawings had been scored earlier by a panel of expert registered architects. The automated technique was able to reproduce the human jurors' ratings for many drawings. In particular, drawings that the automated technique failed were quite likely to have been failed by human jurors as well.

source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	In this paper we present a hierarchical decision support system for the allocation of organisations to available buildings, and for the allocation of employees of an organisation to the work units of a building. For both allocation problems a mathematical model and optimisation algorithm is developed, taking into account the relevant criteria, such as the extent to which the allocated floorspace is in accordance with the standards, and the extent to which departments are housed in connecting zones of a building. The decision support system is illustrated by two practical applications.

title	Decision support system for air base construction operations
source	The Int. Journal of Construction IT 1(2), pp. 69-82
summary	The United States Air Force has recently introduced a CAD software performing air base planning and operability functions. This paper presents a prototype system developed to support that software in enhancing decision-making processes for construction operations, by integrating its CAD/graphics capabilities with a database management system (DBMS). The system addresses the complexity and unique nature of the air base environment and takes due account of the importance of the efficient utilization of resources. It assists in the generation of alternative solutions and furnishes comparative and indicative evaluations of these, thus providing the decision maker with proper guidance towards the expeditious selection of good solution. System fundamentals and the rationale behind them are described. A typical scenario is presented, illustrating the concepts developed and demonstrating the potential benefits of the system as a practical decision-support tool. Although originally aimed for an air base environment, the proposed solution could also readily apply to civilian systems of similar characteristics.
