summary	Modern architecture takes advantage of the greatly increasing design possibilities. Yet, architects are not just a new group of CAD users. Scale and construction technologies pose new challenges to engineering and design. We are convinced that those can be met more effectively with a solid understanding of geometry. Thus, an academic CAAD curriculum has to meet these requirements. We introduce our approach taken at TU Vienna and focus on the first-term mandatory course on geometry for architecture.

title	Creating the Electronic Design Studio: Development of a Heterogeneous Networked Environment at Harvard's Graduate School of Design
doi	https://doi.org/10.52842/conf.ecaade.1992.225

summary	The migration of design education to reliance on computer-based techniques requires new ways of thinking about environments which can effectively support a diverse set of activities. Both from a spatial standpoint and a computing resource standpoint, design studios must be inevitably reconfigured to support new tools and reflect new ways of communicating. At Harvard's GSD, a commitment to incorporating computer literacy as a fundamental component of design education enables us to confront these issues through the implementation of a heterogeneous network imbedded in an electronic design environment. This evolving prototype of a new design studio, its development and its potential, will be the subject of this paper. A new style design environment is built upon an understanding of traditional techniques, and layered with an awareness of new tools and methods. Initially we borrow from existing metaphors which govern our interpretation of the way designers work. Next we seek to extend our thinking to include allied or related metaphors such as the library metaphor which informs collections of software and data, or the laboratory metaphor which informs workspace groupings, or the transportation metaphor which informs computer-based communications such as electronic mail or bulletin boards, or the utility services metaphor which informs the provision of network services and equipment. Our evaluation of this environment is based on direct feedback from its users, both faculty and students, and on subjective observation of the qualitative changes in communication which occur between and among these groups and individuals. Ultimately, the network must be judged as a framework for learning and evaluation, and its success depends both on its ability to absorb our existing metaphors for the process of design, and to prefigure the emerging metaphors to be envisioned in the future.

title	Visual Intelligence
source	Norton Publishing, New York
summary	After his stroke, Mr. P still had outstanding memory and intelligence. He could still read and talk, and mixed well with the other patients on his ward. His vision was in most respects normal---with one notable exception: He couldn't recognize the faces of people or animals. As he put it himself, "I can see the eyes, nose, and mouth quite clearly, but they just don't add up. They all seem chalked in, like on a blackboard ... I have to tell by the clothes or by the voice whether it is a man or a woman ...The hair may help a lot, or if there is a mustache ... ." Even his own face, seen in a mirror, looked to him strange and unfamiliar. Mr. P had lost a critical aspect of his visual intelligence. We have long known about IQ and rational intelligence. And, due in part to recent advances in neuroscience and psychology, we have begun to appreciate the importance of emotional intelligence. But we are largely ignorant that there is even such a thing as visual intelligence---that is, until it is severely impaired, as in the case of Mr. P, by a stroke or other insult to visual cortex. The culprit in our ignorance is visual intelligence itself. Vision is normally so swift and sure, so dependable and informative, and apparently so effortless that we naturally assume that it is, indeed, effortless. But the swift ease of vision, like the graceful ease of an Olympic ice skater, is deceptive. Behind the graceful ease of the skater are years of rigorous training, and behind the swift ease of vision is an intelligence so great that it occupies nearly half of the brain's cortex. Our visual intelligence richly interacts with, and in many cases precedes and drives, our rational and emotional intelligence. To understand visual intelligence is to understand, in large part, who we are. It is also to understand much about our highly visual culture in which, as the saying goes, image is everything. Consider, for instance, our entertainment. Visual effects lure us into theaters, and propel films like Star Wars and Jurassic Park to record sales. Music videos usher us before surreal visual worlds, and spawn TV stations like MTV and VH-1. Video games swallow kids (and adults) for hours on end, and swell the bottom lines of companies like Sega and Nintendo. Virtual reality, popularized in movies like Disclosure and Lawnmower Man, can immerse us in visual worlds of unprecedented realism, and promises to transform not only entertainment but also architecture, education, manufacturing, and medicine. As a culture we vote with our time and wallets and, in the case of entertainment, our vote is clear. Just as we enjoy rich literature that stimulates our rational intelligence, or a moving story that engages our emotional intelligence, so we also seek out and enjoy new media that challenge our visual intelligence. Or consider marketing and advertisement, which daily manipulate our buying habits with sophisticated images. Corporations spend millions each year on billboards, packaging, magazine ads, and television commercials. Their images can so powerfully influence our behavior that they sometimes generate controversy---witness the uproar over Joe Camel. If you're out to sell something, understanding visual intelligence is, without question, critical to the design of effective visual marketing. And if you're out to buy something, understanding visual intelligence can help clue you in to what is being done to you as a consumer, and how it's being done. This book is a highly illustrated and accessible introduction to visual intelligence, informed by the latest breakthroughs in vision research. Perhaps the most surprising insight that has emerged from vision research is this: Vision is not merely a matter of passive perception, it is an intelligent process of active construction. What you see is, invariably, what your visual intelligence constructs. Just as scientists intelligently construct useful theories based on experimental evidence, so vision intelligently constructs useful visual worlds based on images at the eyes. The main difference is that the constructions of scientists are done consciously, but those of vision are done, for the most part, unconsciously.

source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 375-386
summary	A new design model is presented. Information on the design is distributed over multiple self-contained design perspectives and translation functions between design perspectives. Inconsistencies between specifications in different design perspectives introduced by human designers are temporarily tolerated in order to support creative design processes. The implementation of a design support system currently under evaluation is outlined.

title	Combined web crippling and bending moment failure of first-generation trapezoidal steel sheeting : experiments, finite element models, mechanical models
source	Eindhoven University of Technology
summary	Cold-formed trapezoidal sheeting of thin steel plate is a very popular product for building construction. It combines low weight and high strength and is economical in use. Current design rules, which predict sheeting failure for an interior support, do not provide sufficient insight into the sheeting behaviour, and can differ up to 40% in their predictions. To develop a new design rule, this thesis presents new experiments in which first-generation sheeting behaviour is studied for practical situations. The experiments show that after ultimate load, three different post-failure modes arise. Mechanical models have been developed for the three post-failure modes. These models can help to explain why a certain post-failure mode occurs. Finite element models were used to simulate the experiments. Studying stress distributions with finite element simulations, it can be seen that there are only two ultimate failure modes at ultimate load. One of these ultimate failure modes is not relevant for practice. A mechanical model has been developed for the other ultimate failure mode. This model performs as well as the current design rules, and it provides insight into the sheeting behaviour.

title	Co-evolutionary Spatial-Structural Building Design Optimisation including Facade Openings
doi	https://doi.org/10.52842/conf.caadria.2021.1.431
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 1, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 431-440
summary	Within co-evolutionary building design simulations, a spatial design can be automatically transformed into a structural design, and its structural performance can lead to modifications of the spatial design, after which a new cycle starts. This paper presents two procedures to include facade openings in these simulations, to allow for future simulations that include lighting. The first procedure reassigns a fixed pattern of facade openings to the spatial design each cycle, whereas the second procedure only assigns a pattern at the start, and modified spaces inherit their openings. For structural peformance, it is concluded that deterministic vertical opening patterns, with a low facade opening ratio, lead to a reduction of the number of stories, and consequently optimise the structural design. Also, it is shown that the first procedure maintains facade opening ratios during simulations, whereas the second procedure leads to decreasing openness, and more unconnected spaces. As such the first procedure is considered for an upcoming project, where spatial-structural-thermal-lighting building optimisation is investigated, including non-rectangular spatial designs.

title	Improving Design using Autonomous Spatial and Structural Generators
doi	https://doi.org/10.52842/conf.ecaade.2005.743
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 743-750
summary	During a building design process, a structural designer transforms a spatial design into a structural design and this structural system can be improved by optimisation methods or expert views of other structural designers. The improved structural system allows the architect a new spatial design, which can be transformed or altered again by the architect. This design cycle can be repeated several times and is defined as interaction of spatial and structural design. Case studies are used to demonstrate that this interaction occurs in practice and is needed to improve building quality. This paper presents a program with more or less autonomous spatial and structural generators. Each generator will facilitate one direction in the interaction process. Then using both consecutively leads to a design method that provides interaction between spatial and structural design. For the spatial generator, named “room positioning with structural constraints” a space allocation technique is used including constraints that handle structural boundary conditions. A zone generator based on pattern recognition and shape grammars handle the structural design. A Prolog-2 program was developed to demonstrate the application of the two proposed generators. “Zone generation” is performed per building storey and thus represents a horizontal two-dimensional procedure. Similarly “room positioning with structural constraints” is a planar vertical operation. In future these procedures can be made three-dimensional.

summary	Besides the development of benchmarks for structural optimization, this report shows that optimization techniques can be used not only for changing structural elements, but also for changing structural topology and thus potentially whole building designs. This is relevant for computer aided structural design in general and for interaction of spatial and structural design as presented by the author at eCAADe 2005.

source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 483-492
summary	Recently, in the research field of combined architecture and structural design, the idea of a so-called research engine has been developed. During its development, initially the intention was to develop a design-support tool, however, it now becomes clear that it may serve as a general framework for several applications. In this paper the new possibilities for the applications will be presented. As a result, a bird’s-eye view is developed on a set of applications that are often presented separately and without a larger framework in literature. In conclusion, several applications used for CAAD and CASD (Computer Aided Structural Design) can be seen as derivatives of a research engine. The other way round, the research engine can be modified and new applications may result.

summary	A particular application for informed building design concerns the intelligent synthesis of a structure system for a conceptual spatial design. As part of this synthesis, the positioning of structural elements is normally related to the surfaces of the spaces that form the spatial design. It is shown that if surfaces of zones are taken instead, with a zone being a group of complete or possibly incomplete spaces, structural performance of the space-based systems may be Pareto dominated by the zone-based systems. This indicates that zones are a useful concept to improve structural performance. Also, the variety of zoned designs for a single spatial design delivers, together with a single structural grammar, many variants for a structure system.

summary	Conventional CAD systems rarely provide automated conversion of general building design representations (BDR) into the simulation domain representations (SDR) required for various detailed simulations. The Simulation Environment for Modeling Performance (SEMPER) project has demonstrated such an automated mapping for buildings with orthogonal geometries. This paper further illustrates automated mapping for buildings with complex (non-orthogonal) geometry.

summary	It is argued that readers are likely to carry away from Donald Knuth's article 'The Concept of a Meta-Font' a falsely optimistic view of the extent to which the design of typefaces and letterforms can be mechanized through an approach depending on describing letterforms by specifying the settings of a large number of parameters. Through a comparison to mathematical logic, it is argued that no such set of parameters can capture the essence of any semantic category. Some different ways of thinking about the problem of the 'spirit' residing behind any letterform are suggested, connecting to current research issues in the field of artificial intelligence

title	Playing with Time - Continuous Temporal Mapping Strategies for Interactive Environments
source	6th Canadian GIS Conference, (Ottawa Natura Resources Canada), pp. 318-329
summary	The growing acceptance of GIS technology has had far- reaching effects on many fields of research. The recent developments in the area of dynamic and temporal GIS open new possibilities within the realm of historical research where temporal relationship analysis is as important as spatial relationship analysis. While topological structures have had wide use in spatial GIS and have been the subject of most temporal GIS endeavours, the different demands of many of these temporally- oriented analytic processes questions the choice of the topological direction. In the fall of 1992 the Montreal Research Group (MRG) of the Canadian Centre for Architecture mounted an exhibition dealing with the development of the built environment in 18th- century Montreal. To aid in presenting the interpretive messages of their data, the MRG worked with the Centre for Landscape Research (CLR) to incorporate the interactive capabilities of the CLR's PolyTRIM research software with the MRG's data base to produce a research tool as well as a public- access interactive display. The interactive capabilities stemming from a real- time object- oriented structure provided an excellent environment for both researchers and the public to investigate the nature of temporal changes in such aspects as landuse, ethnicity, and fortifications of the 18th century city. This paper describes the need for interactive real- time GIS in such temporal analysis projects and the underlying need for object- oriented vs. topologically structured data access strategies to support them.

summary	This paper is based on a hypothesis that games can be used to support design decisions in a variety of complex situations. To explore this proposition, the research described below focuses on two aspects. Firstly, it experiments with the potential of games to be socially provocative. And secondly, it applies the induced provocations in support of collective imagination. This discussion is supported by a practical case study: a working prototype of a smartphone game that simulates urban cycling. The paper discusses utilisation of this game by diverse stakeholders in a workshop that sought to advance decision-making in a particularly vexatious stalemate.

title	Genetic Algorithms
source	Scientific America, July 1992
summary	Living organisms are consummate problem solvers. They exhibit a versatility that puts the best computer programs to shame. This observation is especially galling for computer scientists, who may spend months or years of intellectual effort on an algorithm, whereas organisms come by their abilities through the apparently undirected mechanism of evolution and natural selection. Pragmatic researchers see evolution's remarkable power as something to be emulated rather than envied. Natural selection eliminates one of the greatest hurdles in software design: specifying in advance all the features of a problem and the actions a program should take to deal with them. By harnessing the mechanisms of evolution, researchers may be able to "breed" programs that solve problems even when no person can fully understand their structure. Indeed, these so-called genetic algorithms have already demonstrated the ability to made breakthroughs in the design of such complex systems as jet engines. Genetic algorithms make it possible to explore a far greater range of potential solutions to a problem than do conventional programs. Furthermore, as researchers probe the natural selection of programs under controlled an well-understood conditions, the practical results they achieve may yield some insight into the details of how life and intelligence evolve in the natural world.

summary	Architects have developed and employed parametric design strategies to both address these performance related concerns and improve their production. Though these strategies have improved architectural design, they are not being used to their full extent in the design process. I propose taking the use of computers in aiding architectural design one step further; information and data should INFORM the project, driving the creation of a building FORM enabling it to PERFORM at higher levels than traditional design.
