title	A Homology-Based Mapping Approach to Concurrent Multi-Domain Performance Evaluation
doi	https://doi.org/10.52842/conf.caadria.1997.237
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 237-246
summary	Over the past several years there have been a number of research efforts to develop integrated computational tools which seek to effectively support concurrent design and performance evaluation. In prior research, we have argued that elegant and effective solutions for concurrent, integrated design and simulation support systems can be found if the potentially existing structural homologies in general (configurational) and domain-specific (technical) building representations are creatively exploited. We present the use of such structural homologies to facilitate seamless and dynamic communication between a general building representation and multiple performance simulation modules – specifically, a thermal analysis and an air-flow simulation module. As a proof of concept, we demonstrate a computational design environment (SEMPER) that dynamically (and autonomously) links an object-oriented space-based design model, with structurally homologous object models of various simulation routines.

title	A Middle Way to Integration
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Integration in computer-aided design denotes systematic incorporation of multiple domain applications within a unified computational design support environment. At one end of the spectrum of integration efforts, there is a top-down approach involving an all-encompassing maximal building representation. On the other end, there is bottom-up approach involving the ad hoc and as-needed production of translator and mediator routines to enable various existing applications to communicate with each other. This paper describes the development of a design support system which represents a middle way to integration: while it assumes that, at a fundamental level, some shared notation of the constitutive building entities and their spatial relationships is sine qua non, it assumes that this notation is not a primary necessity, but must be tested against the requirements of the "down-the-line" manipulators of the entities encapsulated by it.

title	Open Simulation Environments: A “Preference-Based” Approach
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 195-214
summary	This paper introduces in conceptual, algorithmic and implementation terms, the notion of an "open" simulation environment as a "multidirectional" approach to computer-aided performance modelling. A "preference- based" formalization of design intentions/criteria is proposed to cope with the "ambiguity" problem through dynamic control of degrees of freedom of relevant design-related parameters during the interactive design process. A prototypical realization of an open simulation environment called "GESTALT' for simultaneous treatment (parametric manipulation) of various design and performance variables is demonstrated. Some preliminary results of computer-assisted generation of performance-responsive designs are presented.

title	Towards a framework for evaluation of computer visual simulations in environmental design
source	Design Studies 22 (2) (2001) pp. 193-209
summary	Research has been conducted into the assessment of visual simulation as a credible method for predicting future environments, especially in building and landscape evaluation. Despite this work a conceptual framework to guide research and practice in this field has not been developed. The recent and increasingly widespread use of computer simulation in design has created an urgent need to develop a conceptual framework which can test prevailing assumptions and provide the basis for the development of an accepted theory in the field. This paper proposes such a framework, and identifies and relates the significant variables, which impact upon the application of visual simulation in an environmental design, task-orientated context.

title	Digital Architecture at Crossroads – Transition from Simulation and Visualisation to Information Modelling
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 5
summary	Digital architecture is at an exciting but challenging stage of its development. Past decades have witnessed important developments in computer-generated architectural representations. These tools have complemented and, in some cases, superseded the traditional forms of design and communication. In parallel with progress in computer graphics, advances in computer generated architectural representations have evolved to deliver photorealistic computer generated imagery. However, there is evidence to suggest that these advances have not significantly enhanced collaborative practices. It was acknowledged that to address the fragmentation of the industry, a fundamental change to deliver digital architecture was needed. Dealing with the requirements for an improved co-ordination and co-operation between designers and other stakeholders to encourage more integration has therefore become a central issue in the last decade. It was also recognised that significantly more intelligence needs to be brought to bear on the decision-making process if the targets set by the sustainability agenda are to be met. The quest for an improved quality of information and decision making has shifted the emphasis from computer-generated imagery to integrated building information. The recent emergence of building information modelling (BIM) constitutes one of the most exciting developments in the field. It was suggested that BIM will deliver considerable sophistication and judgment in decision-making. This keynote speech seeks to examine the implications of the transition of digital architecture from simulation and visualisation to information modelling. It aims to shed light on the methodological and technological challenges facing practitioners, researchers, and software developers, as a result of the early adoption of BIM.

title	The Re-Engineering Project Developing Pedagogical Frameworks for Early Stage Collaborative Design between Engineers and Architects
doi	https://doi.org/10.52842/conf.acadia.2006.200
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 200-212
summary	We describe a research-based design studio entitled Reengineering, brought together by two research groups with the aim of further understanding factors that promote conceptual design for interdisciplinary work between architects and engineers. The aim, through a sequence of semi-structured projects, was to reflect upon the students’ attempts both at a co-rational (Fischer 2006) approach to design and at the culmination of each stage to return to the beginning albeit with a more sophisticated understanding of the work. Through this process we found that a close-coupled design process was achieved between these disciplines at a conceptual level but when the participants developed a shared understanding supported by a project language and when each eschewed their discipline specific tools a co-rational approach was obtained.

summary	Through a model of engaging research in practice, we present the development of a technique for digitally resolving three-dimensional curves for documentation and fabrication. We suggest it is possible to distinguish the power of the computer as a design tool in the design development process, where the description of complex forms are not well served by the established methods of orthogonal representation.

title	Hybridized Measurement: Interpreting historical images of Sagrada Família Church in Barcelona using CAD-based digital photogrammetry
doi	https://doi.org/10.52842/conf.ecaade.2002.448
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 448-455
summary	This paper gives an account of the extrapolated use of digital photogrammetry undertaken by the Spatial Information Architecture Laboratory (SIAL) in the pursuit for new interpretations of historical images at the Sagrada Família Church. The work is an extension of the research activities undertaken as part of the Australian Research Council (ARC) Strategic Partnerships with Industry – Research and Training (SPIRT) project New onto Old : 3D flexible computer modelling to aid heritage building restoration, recycling and extension, where digital photogrammetry was first explored as a measurement tool for non-specialist implementation. The research makes use of the link between Computer Aided Design (CAD) and digital photogrammetry in a reverse manner, using built spatial data to produce orthographic rectified images of what was intended from the historical drawings and models of the architect Antoni Gaudí (1852-1926).

summary	New design opportunities that are facilitated by cross-disciplinary collaboration in both practice and research are available through the use of high level design software that simultaneously offers real time access to both analysis and design geometry in shared three-dimensional digital models. Here we present a collaborative research project between architects and structural engineers for the design of a pedestrian bridge, conceived to test current digital design processes in architectural and structural engineering practice with those in research through the use of models of parametrically defined associative geometry. In this project, the digital model’s architectural design geometry was constrained by the bridge’s fabrication methods and linked with its engineering analysis. Iterations of the design geometry were then optimised or ‘solved’ to produce variations according to the design parameters offered up for change. The shift of the professions from the plane to digital space exposes the possibilities of new design techniques with the exchange of design parameters potentially operating as a digital dialogue between the disciplines—a kind of digital version of Antoni Gaudi’s funicular hanging model—a metaphor of the digital space that has been developed for this project.

title	Understanding Virtual Design Studios
source	Springer, London
summary	Understanding Virtual Design Studios examines the issues involved in setting up and running a virtual design studio. Rather than focusing on the technology or how to apply it, the reader is presented with an interdisciplinary framework for understanding, organising, running and improving virtual design studios both in professional and educational practice. The authors assess the potential benefits, such as improved creativity and collaboration, and highlight the areas in which our understanding needs to improve; How people collaborate in an environment where interaction is mediated by shared computer resources; How to organise and manage a distributed workspace efficiently; How people represent and communicate design ideas in an electronic form. Of interest to both design professionals and researchers interested in computer-mediated collaboration, this volume will also be of interest to anyone who needs a clear picture of what this new technology can do for them

title	Variations on the Virtual Design Studio
source	Proceedings of Computer-Supported Collaborative Work in Design
summary	There are numerous approaches and techniques for setting up an environment for collaborative design. The most common approach is to extend the desktop environment to include tools for meeting and sharing files. This approach takes the individual work environment and adds tools for communicating with others. An alternative approach is to create a virtual world environment in which the collaborators meet, work, and organise their projects. This approach differs conceptually because it creates a sense of place that is unique to the project, sort of a shared office space. A variation on this approach is to create a virtual world that is the model of the product being designed. This is a more obvious choice when the product is an architectural design, but it can be extended to other kinds of design. This approach is essentially collaborating within the design. We present the three approaches and comment on their strengths and weaknesses.

title	Developing case-based reasoning for structural design
source	IEEE Expert
summary	Case-based systems enable users to retrieve previously known designs from memory and adapt them to fit the current design problem. The four case-based design systems described here illustrate how various implementations achieve design assistance or design automation objectives. Case-based reasoning is a problem-solving technique that makes analogies between a problem and previously encountered situations (cases) relevant to solving the problem. Using CBR as a design process model involves the subtasks of recalling previously known designs from memory and adapting these design cases or subcases to fit the current design context. The detailed development of this process model for a particular design domain proceeds in parallel with the development of the case representation, the case memory organization, and the necessary design knowledge. The selection of an information representation paradigm and the details of its use for a problem-solving domain depend on the intended use of the information, the project information available, and the nature of the domain. CBR could be used to develop and implement a CBR system. Although that sounds circular, if CBR is a viable approach to problem solving, it can be applied to the development of the reasoning system itself. Toward that end, this article presents four "cases" of case-based building design systems that we've developed at the University of Sydney: CaseCAD, CADsyn, Win, and Demex. These systems exemplify alternative case memory contents and organizations and provide insight into different potential implementations of the recall and adaptation subprocesses.

title	Modelling design exploration as co-evolution
source	Microcomputers in Civil Engineering, 11:192-207
summary	Most computer-based design tools assume designers work with a well defined problem. However, this assumption has been challenged by current research. The explorative aspect of design, especially during conceptual design, is not fully addressed. This paper introduces a model for problem-design exploration, and how this model can be implemented using the genetic algorithm (GA) paradigm. The basic GA, which does not support our exploration model, evaluates individuals from a population of design solutions with an unchanged fitness function. This approach to evaluation implements search with a prefixed goal. Modifications to the basic GA are required to support exploration. Two approaches to implement a co-evolving GA are presented and discussed in this paper: one in which the fitness function is represented within the genotype, and a second in which the fitness function is modelled as a separately evolving population of genotypes.

title	An Experimental Study of Computer Mediated Collaborative Design
source	International Journal of Design Computing, Key Centre of Design Computing, University of Sydney, Sydney
summary	The use of computer technology in design practice is moving towards a distributed resource available to a team of designers. The development of software to support designers has traditionally been based on the assumption that there will be a single person using the software at a time. Recent developments have enabled the feasibility of software for two or more simultaneous users, leading to the possibility of computer mediated collaborative design (CMCD), where the computer plays the role of mediator and design information handler. There is the potential for the computer to play a more active role in collaborative design through enhanced visibility of 3D models and assistance in generating alternative designs and design critiques. With this potential the computer not only mediates the collaborative design process but actively supports the designers. Research in integrated CAD, multimedia and design database systems, virtual design studios, and design protocol studies provide the basis for a formal study of CMCD. We have developed an experimental methodology to study the difference in design semantics documented using computer applications when designing alone as compared to designing collaboratively. This methodology can be applied to study other aspects of CMCD.

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.
