title	Performance Analysis and Conceptual Design
source	School of Architecture and Fine Arts, University of Western Australia
summary	A significant amount of the research referred to by Manning has been directed into the development of computer software for building simulation and performance analysis. A wide range of computational tools are now available and see relatively widespread use in both research and commercial applications. The focus of development in this area has long been on the accurate simulation of fundamental physical processes, such as the mechanisms of heat flow though materials, turbulent air movement and the inter-reflection of light. The adequate description of boundary conditions for such calculations usually requires a very detailed mathematical model. This has tended to produce tools with a very engineering-oriented and solution-based approach. Whilst becoming increasingly popular amongst building services engineers, there has been a relatively slow response to this technology amongst architects. There are some areas of the world, particularly the UK and Germany, where the use of such tools on larger projects is routine. However, this is almost exclusively during the latter stages of a project and usually for purposes of plant sizing or final design validation. The original conceptual work, building form and the selection of materials being the result of an aesthetic and intuitive process, sometimes based solely on precedent. There is no argument that an experienced designer is capable of producing an excellent design in this way. However, not all building designers are experienced, and even fewer have a complete understanding of the fundamental physical processes involved in building performance. These processes can be complex and often highly inter-related, often even counter-intuitive. It is the central argument of this thesis that the needs of the building designer are quite different from the needs of the building services engineer, and that existing building design and performance analysis tools poorly serve these needs. It will be argued that the extensive quantitative input requirement in such tools acts to produce a psychological separation between the act of design and the act of analysis. At the conceptual stage, building geometry is fluid and subject to constant change, with solid quantitative information relatively scarce. Having to measure off surface areas or search out the emissivity of a particular material forces the designer to think mathematically at a time when they are thinking intuitively. It is, however, at this intuitive stage that the greatest potential exists for performance efficiencies and environmental economies. The right orientation and fenestration choice can halve the airconditioning requirement. Incorporating passive solar elements and natural ventilation pathways can eliminate it altogether. The building form can even be designed to provide shading using its own fabric, without any need for additional structure or applied shading. It is significantly more difficult and costly to retrofit these features at a later stage in a project’s development. If the role of the design tool is to serve the design process, then a new approach is required to accommodate the conceptual phase. This thesis presents a number of ideas on what that approach may be, accompanied by some example software that demonstrates their implementation.

title	Level-of-Detail Visualization of Architectural Models
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 831-836
summary	The work presented in this paper aims to use level-of-detail representation in realizing interactive walkthroughs or ignoring useless details in large architectural models. In order to choose the right representation of a model, we have to evaluate the error committed when using a simplified version instead of the full description of an object. This error depends on the object deformation during the simplification process but also on the importance of this object in the current viewing conditions. This "visible" error is used with different visualization strategies to find the model representation which satisfies either a quality criterion or a cost condition.

title	Integrating Design Tools within a Human Collaborative Working
source	The Int. Journal of Construction IT 5(2), pp. 47-73
summary	This paper stresses the importance of establishing a collaborative working context as the basis for design integration. Within a virtual studio environment framework, a hybrid architecture for design tool integration is presented. Each design tool is wrapped as an autonomous service provider with its own data store; thus the project design data is physically distributed with the design tools. A global product model, which is augmented with meta-data description, is employed to provide a common vocabulary for communications and to assist the management of the distributed resources and activities. Collaboration-aware information is modelled and structured through the meta-data model and a tool model. Based on this, mechanisms for tool service coodination in varying modes are developed. It is then illustrated, through an implemented prototype system, how the integrated design tools might be used in human design work.

title	Executable Drawings: The Computation of Digital Architecture
doi	https://doi.org/10.52842/conf.acadia.1998.172
source	Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 172-187
summary	Architectural designs are principally represented by drawings. Usually, each drawing corresponds to one design or aspects of one design. On the other hand, one executable drawing corresponds to a set of designs. These drawings are the same as conventional drawings except that they have computer code or programs embedded in them. A specific design is the result of the computer executing the code in a drawing for a particular set of parameter values. If the parameters are changed, a new design or design variation is produced. With executable drawings, a CAD system is also a program editor. A designer not only designs by drawing but also programming. It fuses two activities: the first, drawing, is basic in architectural practice; and the second, progamming, or specifying the relation of outputs from inputs, is basic in computer system development. A consequence of executable drawings is that architectural form is represented by graphical entities (lines or shapes) as well as computer code or programs. This type of architecture we call digital architecture. Two simple examples are presented: first, the design of a building in terms of an executable drawing of the architects, Sangallo the Younger and Michelangelo, and second, a description of an object oriented implementation of a preliminary prototype of an executable drawing system written in 1997 which computes a simple office layout.

title	Creation of concept shape designs via a virtual reality interface
source	Computer-Aided Design, Vol. 29 (8) (1997) pp. 555-563
summary	This paper describes an approach for creating concept shape designs in a virtual reality environment--COVIRDS (COnceptual VIRtual Design System. Conceptdesign refers to the ab initio design of a product or part. In concept design, the product details such as shape features and exact dimensions are not rigidly definedand the designer has some freedom in determining the shape and dimensions of the product. Current CAD require the designer to specify shape and dimensions tocreate CAD models of products even though these are probably not necessary at the concept development stage. COVIRDS overcomes these drawbacks by providing abi-modal voice and hand-tracking based user interface to the VR-based CAD modeling environment. This interface allows rapid concept design creation withoutrequiring time consuming shape description and the tedious specifications of exact dimensions.

title	Exploring the Possibilities of Conjoint Measurement as a Decision-Making Tool for Virtual Wayfinding Environments
doi	https://doi.org/10.52842/conf.caadria.1997.061
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. 61-71
summary	Virtual reality systems may have a lot to offer in architecture and urban planning when visual and active environments may have a dramatic impact on individual preferences and choice behaviour. Conjoint analysis involves the use of designed hypothetical choice situations to measure individuals’ preferences and predict their choice in new situations. Conjoint experiments involve the design and analysis of hypothetical decision tasks. Alternatives are described by their main features, called attributes. Multiple hypothetical alternatives, called product profiles, are generated and presented to respondents, who are requested to express their degree of preference for these profiles or choose between these profiles. Conjoint experiments have become a popular tool to model individual preferences and decision-making in a variety of research areas. Most studies of conjoint analysis have involved a verbal description of product profiles, although some studies have used a pictorial presentation of production profiles. Virtual reality systems offer the potential of moving the response format beyond these traditional response modes. This paper describes a particular aspect of an ongoing research project which aims to develop a virtual reality based system for conjoint analysis. The principles underlying the system will be illustrated by a simple example of wayfinding in a virtual environment.

summary	Description of class research from 1997-2 to 2000-1 in “Applied Computing in Architecture” conducted in the sixth semester of the Architecture Program at Faculdade de Belas Artes de São Paulo. The study is intended to analyze, evaluate and discover new paradigms in the introduction/application of class methodologies of teaching the use of computer in the design process. Our intention is to verify the students natural understanding of the principles of 3D digital modeling by introducing new tools for defining space and form, using the computer as a communication/representation system, and not only as a mimetized production tool. The challenge was to find a natural syntony between the digital projectual process and the learning process. At the end of each semester we evaluated the results and redirected the class proposals.

title	Information management in creative engineering design and capabilities of database transactions
source	Automation in Construction 7 (1) (1997) pp. 55-69
summary	This paper examines the information management requirements and sets forth the general criteria for collaboration and concurrency control in creative engineering design. Our work attempts to recognize the full range of concurrency, collaboration and complex transactions structure now practiced in manual and semi-automated design and the range of capabilities needed as the demands for enhanced but flexible electronic information management unfolds.The objective of this paper is to identify new issues that may advance the use of databases to support creative engineering design. We start with a generalized description of the structure of design tasks and how information management in design is dealt with today. After this review, we identify extensions to current information management capabilities that have been realized and/or proposed to support/augment what designers can do now.Given this capability-based starting point, we review existing database and information management capabilities, as presented in the literature. In the review, we identify the gaps between current concurrency and collaboration technology and what is needed or would be desirable. Our objective is to assess current research and to identify new issues that may advance the use of databases to support creative engineering design.

source	AVOCAAD First International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-01-09] Brussels (Belgium) 10-12 April 1997, pp. 227- 234
summary	Thinking of using computers in architecture, we have probably already learnt that there is much more than just one general way of doing so. At the same time, the general description of the field - i.e. the 'title' Computer Aided Architectural Design' has become a rhetorical figure - actually it covers much more activities than those just aiding design. To some extent computers change architecture introducing new values into it. This does not mean that they change architecture at all, but these new values begin to exist pararelly to the already present and accepted ones. In such sense architecture is changed - one of the possible branches of development is the one related to computers (no matter how complex this branch itself is).

source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 571-589
summary	This paper belongs to a suite of three interrelated papers. The two others are 'The VEGA Platform' and 'A Dynamic Product Model'. These two companion papers are also based on the VEGA project. The ESPRIT project VEGA (Virtual Enterprises using Groupware tools and distributed Architectures) has the objective to develop IT solutions enabling virtual enterprises, especially in the domain of architectural design and building engineering. VEGA shall give answers to many questions of what is needed for enabling such virtual enterprise from the IT side. The questions range from technologies for networks, communication between distributed applications, control, management of information flow to implementation and model architectures to allow distribution of information in the virtual enterprises. This paper is focused on the product model aspect of VEGA. So far modeling experts have followed a more or less centralized architecture (central or central with 4 satellites'). Is this also the architecture for the envisaged goal? What is the architecture for such a distributed model following the paradigm of modeling the , natural human' way of doing business? What is the architecture enabling most effective the filtering and translation in the communication process. Today there is some experience with 'bulk data' of the document exchange type. What is with incremental information (not data) exchange? Incremental on demand only the really needed information not a whole document. The paper is structured into three parts. First there is description of the modeling history or background. the second a vision of interoperability in an distributed environment from the users coming from architectural design and building engineering view point. Third is a description of work undertaken by the authors in previous project forming the direct basis for the VEGA model. Finally a short description of the VEGA project, especially the VEGA model architecture.

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. 29-39
summary	The paper describes a relations-based graphic environment of shape delineation and dynamic drawing manipulation that can provide a qualitatively different way to explore shape, dimension and geometric organization. Relational description of shapes based on the concept of construction or regulating lines is introduced as an explicit formulation of a strategy to form generation and creative discovery. A limited prototype of the relations-based graphic system, called ReDRAW, is briefly described and the implications of its use in conceptual architectural design are discussed.

title	Form Language and Style Description
source	Design Studies 18, 3, pp. 249-274
summary	This paper presents a `style description framework' for the analysis of style as it is exhibited by objects, artifacts and, particularly, products. The framework equips a designer with both the ability to analyse existing styles and to describe new styles for target markets. A `style profile' consists of a set of polar adjective scales and associated weighting mechanisms. Within the profile, stylistic attributes -- in the form of values given on the scales -- are grouped into six categories: form elements, joining relationships, detail treatments, materials, colour treatments and textures. Two weighting mechanisms, an importance index and confidence factor, fine-tune the description. The style profile can be used not only to communicate styles between designers and computers, but also to accumulate formal style knowledge.

source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 331-344
summary	The systematic use of reliable modeling data is believed to improve the building design quality. The key term here is "reliability". There is general agreement that reliability in the context of modeling- assisted CAAD depends on the accurate description of both contextual parameters (climate, site, etc.) and ~building features (geometric and non-geometric properties) as well as the validity of the underlying simulation algorithms. In this paper, we specifically address the importance of detailed contextual information and computational algorithms for the reliability of the daylight modeling results.

source	Computer-Aided Design, Vol. 29 (8) (1997) pp. 547-553
summary	This paper presents a description of ISAAC; the Immersive Simulation Animation And Construction program designed and built at the University of North Carolina atChapel Hill (UNC-CH). ISAAC is a scene composition application used for the interactive construction of virtual worlds. In ISAAC you work directly in a virtualenvironment; you position, orient and scale objects using direct and indirect manipulation techniques. ISAAC stores object configurations in ASCII files that it uses torecreate scenes at a later date for further manipulation and interactive exploration. ISAAC is not a modeling program; you create worlds by manipulating pre-generatedthree-dimensional models (which can come from sources such as computer-aided design programs or three-dimensional scanning devices). ISAAC was designed toovercome some of the limitations of working in a virtual environment and to take advantage of the natural and intuitive forms of interaction available in a virtual world.

title	A Hypertextual Didactic Tool for a Maintenance Oriented Design
source	AVOCAAD First International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-01-09] Brussels (Belgium) 10-12 April 1997, pp. 263-275
summary	This paper presents a research concerning the theme of the support didactic tools for a maintenance oriented design. The work takes a starting point in two remarks: the first is the importance of maintainability requirements prevision for the correct planning of a project and for the formulation of maintenance strategies; the second is the lack of information (examples, references, laws, quality and performance plans) easily available for students and designers. The tool thas has been pointed out has the aim to provide the information - belonging to different categories of knowledge - useful for a maintainability conscious design, according the free navigation modalities tipical of hypertextual applications. Starting from a matrix that associates building subsistems and maintainability requirements the student has the possibility to navigate into a network in which it is possible to have information about: european laws concerning maintenance, examples (drawings, pictures and description) of architectures and of industrial components that regard particular maintainability solutions and a plan in which are schematized the appropriate dimensions and the morfological configurations for the maintenance activities. This hypertextual didactic tool has two different educational applications: 1) during design training courses, it can support in self-training about maintenance aspects; 2) it can become a specialistic module inside an integrated CAAD system developed to combine the graphic representation with different performances evalutions.

title	Programming construction robots using virtual reality techniques
source	Automation in Construction 5 (5) (1997) pp. 393-406
summary	The paper describes a new approach to programming construction robots, using virtual reality (VR) techniques. The new approach is needed because both traditional and new methods of programming industrial robots, described in the paper, have specific drawbacks, which become crucial in the construction arena. This is because of the ever-changing environment of construction and its nature, a prototype or one-of-a-kind, industry. As a result, construction robots need much more programming than their industrial counterparts, which is labor intensive using known methods and is not compensated by mass production. The VR approach is demonstrated with the Multi-Purpose Interior Finishing Robot (MPIR) for a masonry task, accompanied by a detailed description of the VR-based programming model and approach.

title	Issues in the Development and Implementation of a Building Project Model for an Automated Building System
source	The Int. Journal of Construction IT 5(2), pp. 75-101
summary	While other generalised building project models have been designed to support computer-based integration between various construction applications, we propose that the project model of an Automated System must be specifically designed for the purpose. The aim of an Automated, Computer Integrated Building Realization System is to automatically generate all of the information required for the design, planning and execution of a building project. The project model forms the foundation of the system, and must therefore include all of the relevant information about the facility and the resources required through the various realisation stages. This paper describes a project model designed and implemented specifically for this purpose and details some of the considerations in its development. The model has been tested for life-cycle applicability in a prototype interface of an Automated System. Its completeness at the final stage has also been validated through description of an existing 10 storey building.

title	An Integrated Software Environment for the Architectural Design Process
source	Proceedings of the International Conference on Applications of Computer Science and Mathematics in Architecture and Building Science (IKM 1997), Weimar, Germany
summary	Many software systems are in common use in the field of architectural design. On the other hand, we consider a complete automation of architectural design as an unlikely proposition and undesirable for the architect. Therefore, the general objective is to support the designer during the whole process of architectural design in order to increase the efficiency and to improve the quality of the results. So far there are different tools providing such functionality. Nevertheless, there are no appropriate tools for many of the sub-processes. Furthermore, the current state of available design software is characterised by a lack of integration of different tools. In this paper we will provide a survey on a project dealing with the solution of both problems. First we will give a general description of the support that software can provide to architects during the design process. We conclude that many different tools are needed which have to be integrated in an open, modular, distributed, user friendly and efficient environment. We will explain the necessity of integration and cover integration technologies. Besides the aspect of integration we also deal with the development of tools which can operate in the integrated design environment. We suggest a strategy where the tool functions are specified on the basis of a transformation from hierarchical process descriptions of architectural design into a hierarchy of tool descriptions.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 136-143.
summary	The hybridization of architectural, biological and robotic agencies Situated in the field of architectural biodesign, InterspeciesForms explores a closer relationship between the fungus Pleurotus ostreatus and the designer in the creation of form. The intention of hybridizing mycelia’s agency of growth with architectural design intention is to generate novel, non-indexical crossbred designed outcomes that evolve preconceived notions of architectural form. Mycelium are threadlike fibrous root systems made up of hyphae, that form the vegetative part of a fungus (Jones 2020). Known as the hackers of the wood wide web (Simard 1997) mycelia form complex symbiotic relationships with other species that inhabit our earth. Michael Lim states “Fungi redefine resourcefulness, collaboration, resilience and symbiosis” (Lim 2022, p. 14). When wandering around the forest to connect with other species or searching for food, fungi form elaborate and entangled networks by spreading their hyphal tips. Shown in Figure 1, this living labyrinth results in the aesthetic formation of an intricate web. Due to the organisms ability to determine the most effective direction of growth, communicate with its surrounding ecosystem, and connect with other species, fungi are indeed an intelligent species with a unique aesthetic that must not be ignored. In drawing on these concepts, I refer to the organism’s ability to search for, tangle, and digest its surroundings as ‘mycelia agency of growth’. It is this specific behavioral characteristic that is the focus of this research, with which I, as the architect, set out to co-create and hybridize with.
