title	The comparison between visual thinking using computer and conventional media in the concept generation stages of design
source	Automation in Construction 10 (3) (2001) pp. 319-325
summary	The computer, the new media, reaches out and influences the behavior of design as it does almost every facet of life. In recent years, much research into the development of computer-aided design has looked at the concept generation stage of the design process. Most of these applied studies have focused on the testing of computer systems. On the other hand, there are also many studies on the visual thinking and cognitive behavior of designers while sketching or drawing in the stage of concept generation. From the synthesis of the two aforementioned disciplines, we can find that there exists a point of deficiency. That is, the cognitive research about designers using computers as sketching media is absent. It is this area that is discussed in the current paper. The fundamental analytic data of this research is the visual process chronicled from the sketching of subjects. The analytic data is the verbal data from the questions that the subjects are asked after sketching. The data is analyzed using three coding schemes. The cognitive appearance while designers generating concepts with computers or conventional media are propounded and discussed in this research.

title	Tolerating Inconsistencies. The Distributed Perspectives Model
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.

summary	Computer, this new kind of media, has influenced the behavior of design to some degree. Among these years, many researches have appeared for the development of computer-aided design. In recent years, such kind of computer-aided studies about the forepart of design, that is the stage of concept generation, have also started to generate. But most of these researches belonged to the kind of applied studies with the test of computer systems. On the other hand, there were many researches about the visual thinking and cognitive behavior of designers while sketching or drawing in the stage of concept generation. From the synthesis of the fore two disciplines, we can find that there existing a point of deficiency, that is the cognitive research about designers using computers as the sketching media is absent. And that is what I want to study and discuss in this research. The fundamental analytic data of this research is the visual process chronicled form the sketching of subjects, and the assistant analytic data is the verbal data from the questions that the subjects are asked after his/her sketching. These data is analyzed by three coding schema. The cognitive appearance while designers generating concepts with computers or conventional media are propounded and discussed in this research.

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	Some Phenomena of Design Thinking in the Concept Generation Stage Using Computer Media
doi	https://doi.org/10.52842/conf.caadria.2000.255
source	CAADRIA 2000 [Proceedings of the Fifth Conference on Computer Aided Architectural Design Research in Asia / ISBN 981-04-2491-4] Singapore 18-19 May 2000, pp. 255-263
summary	Today, the computer media has become more and more important in design process. It is not only used as kind of simulated and presented media. Also, various kinds of research start developing the computer aided design system and probing the possibility of using computers in creative activities. In resent years, many studies concentrate on the forepart of design, the concept generation stage, but most of them are based on conventional media such as papers and pencils. This study attempts to probe the different design thinking phenomenon produced through concept generation by computers and by conventional media; and the effects of the development and presence of design concept generation resulted from the merits and features of the computers themselves. The methodology used here is protocol analysis of gaining subject's verbal data in think-aloud way and then encoding it to analyze. The outcome of this study is to find some phenomena of design thinking when using computers to progress concept generation, and suggest further studies relating to the topic of methodology.

summary	This thesis presents the first basics of an expertsystem to transform a spatial into a structural design. The system thus relates space-allocation techniques and structural design software for stress-engineering. For the implementation Prolog-2 was used. Although in Dutch, the thesis provided background information for more recently written papers for eCAADe (2005) and CAADRIA (2006). The thesis was published as a paper in Design Studies (2006).

title	Simply complex: a case study of construction-driven design using computational methods
doi	https://doi.org/10.52842/conf.caadria.2010.585
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 585-594
summary	This paper explores how fabrication-based criteria can be integrated into design processes through computational methods. Based on the ongoing project of the Library of the Bao’an Cultural Complex in Shenzhen, China (referred as ‘the Library’ in this paper hereafter), this paper discusses the process of the rationalisation of an intuitive architectural form and its subsequent tiling design based on the adaptation to the conventional fabrication techniques of the building façade industry in China. These objectives are followed by the establishment of robust computational systems of automation that provide a concrete basis for the visualisation, the development of envelope details, and the generation of the list of component data for fabrication. This integrative approach is markedly different from a more conventional one, in which computational systems serve as a priori solutions to unconstraint design sketches.

title	In-Between Spaces: Data-driven Analysis and Generative Design for Public Housing Estate Layouts
doi	https://doi.org/10.52842/conf.caadria.2021.2.397
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 2, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 397-406
summary	As Hong Kong constructs increasingly high-density, high-rise public housing estates to increase land use efficiency, public in-between spaces are more constrained, which impacts the quality of social relations, movements and daily practices of residents (Shelton et al. 2011; Tang et al. 2019). Current planning practices are focused on the achievement of quantitative performance measures, rather than qualitative design considerations that support residents experiences and community interaction. This paper presents a new methodology that combines urban analysis and generative design for the regeneration of social housing estates, based on the spatial and social qualities of their in-between spaces.

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.

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.

title	Effects of 3D Zoning of Spatial Designs on the Performance of Structure Systems

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	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

summary	New boroughs are continuously being built in Brasilia, Brazil’s Capital City. The paper deals with the performance of such boroughs concerning sociospatial segregation. A comparison is made between two proposals for a new borough to the West of the North Wing of the Pilot Plan, which was originally designed by Lucio Costa. The first proposal was made by a wellknown architectural studio in Brasilia and is beginning to be implemented. The second proposal is an exercise made by undergraduate students from the School of Architecture of the University of Brasilia, under the supervision of one the authors of the paper. The two proposals present very different performances. In the first case, the borough is set apart from the immediate urban surroundings; there is no direct connection between inner roads and the main arteries that surround the site. In the second case, the students have proposed a scheme that connects the interior areas of the borough to the vicinity; we hardly know where the new borough begins vis-à-vis the neighbouring areas. We argue that there are serious traffic implications in the first case, as well as sociological implications. We deal with traffic modelling, space syntax techniques and geoprocessing tools to prove so. Furthermore, we will show how the building types are as well socially inadequate, for they will imply homogeneous social layers among the inhabitants – namely exclusively high-middle class living in the new area.

title	A Virtual Reality Modeling Tool for Students of Architecture
source	University of Hong Kong, Hong Kong
summary	During a collaborative design session with other universities, several shortcomings, namely long communication response time, lack of common data format for design and ineffective discussion using static image of design, were observed. A solution was proposed by providing a design interface, a. viewing area of the design and a database to store designs and discussion dialogs. This thesis described a VR (virtual reality) modeling tool, the "VR Composer". With the "VR Composer", models are created directly in 3D. This is the design interface of the solution. The "VR Composer" is based on a commercially available VR software. With a head-mounted display, the "VR Composer" immerses the user into a VR environment. This provides a feeling of presence inside the VR environment. New functionality was added to allow user to create and modify objects in VR. There is no common definition for VR.. I have defined VR as Virtual reality is a human-computer interfiwe which allows a user to visualize and interact with the computer-generated three-dimensional environment intuitively.The students of Department of Architecture are requested to test the VR Composer. Although the VR Composer provided basic functionality as a modeling tool, it has to be improvement in many aspects to become an effective tool for modeling.

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.

keywords	Architects largely define the environmental impact a building will cause throughout its life cycle. Especially decisions taken in early design stages have a great influence on the environmental performance. The integration of environmental assessment into the design process requires adequate tools and basic knowledge of the architects using them. This paper discusses both aspects by means of two case studies with students. In both case studies, the goal was to use Life Cycle Assessment (LCA) to optimize the environmental performance of the building in the design process. The results of the first case study proved the benefits of using LCA-based information for decision-making, but some issues of using the tool during the design process became evident. In the second case study an improved LCA-tool was employed that proved to be applicable by all students. Nevertheless, only one group used the feedback to optimize the building design in an iterative process as intended by the supervisors. This leads to the conclusion that the difficulty of environmental design shifted from a lack of adequate assessment tools to the question of the design approach.
