summary	The goal of this paper is to present the feasibility computing tool for the perimeter block housing design in early design process. Firstly, the paper describes briefly issues of perimeter block housing focusing on block design cases of Seoul. Secondly, constraints and requirements of perimeter block housing are analysed and formulated based on specific zone ordinance and regulation. Thirdly application of half-edge data structure is presented for interconnected geometric problem solving. Fourthly, multi-objective optimization algorithm developed is shortly explained as problem solving method. Finally, feasibility-computing software using Java object oriented programming is developed. This can contribute to the tool development that can generate, optimize, evaluate and visualize perimeter block housings in early phases of design process by providing reliable design solutions for stakeholders.

summary	This paper presents a complex adaptive residential quarter planning software. It is developed using Java object oriented programming language and targeting at configuring the tower-type apartment in a dense area during early design stage. Rules are analyzed and formulated based on building code and zone ordinance. Moreover we develop an agent-based modeling with multi-objective optimization algorithm. In this modeling, each agent acts independently according to the rules that are designed to solve the complex geometric problems that are related to physical constraints. At the end, we present a simulation outcome of a case study.

title	A Cognitive Approach to Architectural Style Several Characteristics of Design Thinking in Architecture
doi	https://doi.org/10.52842/conf.caadria.1996.223

summary	Designing is a complicated human behaviour and method, and is often treated as a mysterious "black box” operation in human mind. In the early period as for theory-studying of design thinking, the way of thinking that the researchers took were mostly descriptive discussions. Therefore, they lacked direct and empirical evidence although those studies provided significant exploration of design thinking (Wang, 1995). In recent years as for the study of cognitive science, they have tried to make design "glass box”. That is to try to make the thinking processes embedded in designers publicized. That is also to externalize the design procedure which provided the design studies another theoretical basis of more accurate and deeply researched procedure (Jones, 1992). Hence the studying of design thinking has become more important and the method of designing has also progressed a lot. For example, the classification of the nature of design problem such as ill-defined and well-defined (Newell, Shaw, and Simon, 1967), and different theoretical procedure modes for different disciplines, such as viewing architectural models as conjecture-analysis models and viewing engineering models as analysis-synthesis (Cross, 1991).

title	Integration of Solid Modeling and Data Base Management for CAD/CAM
source	ACM IEEE Design Automation Conference Proceedings (20th : 1983 : Miami Beach, Florida). pp. 367-373 : ill
summary	For the fast growing CAD/CAM technologies, geometric solid modeling plays one of the most important roles. In order to satisfy a variety of engineering applications, an integrated database management system based on solid modeling is highly desirable. In the proposed approach, a concise object representation scheme, Constructive Solid Geometry (CSG), is adopted as the basis for database design. The underlying generic relational model is found to be more adequate than the conventional relational model in characterizing the embedded data abstraction. A systematic method is devised for converting the CSG scheme into a generic model based on the BNF grammar which depicts the CSG scheme. A relational query language, SEQUEL, has been modified to define, control, and manipulate the flat relations which represent the highly structural generic model

title	Automatic Finite- Element Mesh Generation from Geometric Models : A Point Based Approach
source	ACM Transactions on Graphics. October, 1984. vol. 3: pp. 287-311 : ill. includes bibliography
summary	A novel algorithm for automatic finite-element mesh generation is described. It uses constructive solid geometry to provide the geometric data for the object to be meshed. The geometric definition of the object and a value for the required mesh density are the only inputs. The method consists of two stages: point generation and mesh construction over the points. It has been implemented in two dimensions and is capable of generating predominantly 'good' quadrilateral elements. Triangular elements are only created in circumstances under which quadrilateral elements are not feasible

summary	In Taiwan, it is a common phenomenon that landscape, urban spaces, and buildings are not considered as a whole by governments at all levels and private clients. More terribly, the government has never proposed any urban statement for the future. The Minister strongly therefore proposes this statement: 2050 vision Taiwan, aim to design the public spaces for the life of Taiwan in the year 2050. The Council for Culture Affairs plans to spend two years to cover 100 locations and invite 20 design teams to provide new vision of the places. Our design team, AleppoZONE first conducts the initial stage of this project that includes three areas of Taiwan: Taipei as the capital of Taiwan is expected to become a better place reflecting new and old space combination. Hsinchu is planned to explore the prototype for a digital city where digital technology is wellinstalled in the city plaza and public buildings. In the island of Pen-Hu, the ecology and high-tech transportation are equally considered to shape Pen-Hu as an island with nature. In the process, design team successfully synthesizes digital models and dynamic films into virtual and physical coexisting environmental animations by using multiple digital media in realizing the 2050 vision cities. The aim of this research is to give a throughout introduction of this project.

title	On The Design Communication of Cultural Image
doi	https://doi.org/10.52842/conf.caadria.2009.401
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 401-410
summary	In this era, people are no longer satisfied with standardized products. Designers need to implement unique product semantics to attract customers to buy the products. According to this reason, designers are developing a new design approach that puts cultural elements into their products so that they can make people reappreciate their own culture and history. The Olympics is a global event which involves various sport competitions. Before the Beijing Olympic Games, many host nations used to promote their culture through selling a variety of merchandise. It is the first time for the Olympic Games to take place in China which means that it is obviously the right timing to see cultural symbols of China in the merchandises created by the Chinese design team. These designs had introduced Chinese imageries to the whole world. As generally known, traditional culture of Taiwan actually took root from China. Taiwan owns the same ancient history and materials like China. This study explores the cultural identity and analyses the cultural design elements of China. The 2008 Beijing Olympic Games is taken as case study in this research, because it helps people think how to create new value from their own culture. Furthermore, this paper proposes some suggestions on how to create design which represents the image of Taiwan.

title	Versatile Bracketry - Contemporary Fabrication Techniques for Traditional Korean Architecture
source	ACADIA 2022: Hybrids and Haecceities [Projects Catalog of the 42nd Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-7-4]. University of Pennsylvania Stuart Weitzman School of Design. 27-29 October 2022. edited by M. Akbarzadeh, D. Aviv, H. Jamelle, and R. Stuart-Smith. 100-105.
summary	Versatile Bracketry is an architectural experiment employing algorithmic design technology and 3D printing, manipulating Gong-po—a wooden bracket element found in traditional Korean architecture. Although there has been some recognition and reflection toward the inclusion of traditional forms in modern design, the mainstream in Korean architecture has been Western-oriented. However, advanced computation technology provides both a new perspective and approach in this field, and higher productivity and efficiency.

summary	To construct a building that meets the requirements of certification in terms of environmental friendliness, there must be a process that considers the certification criteria from the initial design phase. However, there are numerous complicated task performance procedures to analyse many required items in detail as well as perceive and apply the data requirements efficiently. Currently, Building Information Modeling (BIM) is gaining attention as a solution for environmental problems in architecture. BIM shows precisely how a virtual building is modelled in the real world, thereby providing an objective information and analysis through a simulation. However, the result values of BIM library or modelling may turn out differently as a result of the work environment of designers or users that is not standardized. Therefore, this study applies the modelled and extracted BIM data using the template and library established in the BIM add-in planning and design phase to review in advance the Green Standard for Energy and Environmental Design (G-SEED) assessment by item and manual input of users with the BIM-based (add-in) G-SEED assessment system, thereby providing support to enable users to establish specific strategies in designing green buildings.

title	The Relationship between Problem-Finding and Computing Media in Design Creativity
doi	https://doi.org/10.52842/conf.caadria.2000.277
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. 277-285
summary	Designing is defined as a process of problem-finding and problem-solving. According to studies, the problem-finding during the early period of designing is the key point for influencing creativity, and the study also indicates that the computer originally used for presenting during the late period of designing can also be used during the early stage, but now we lack studies about creativity and computers. This study uses protocol analysis as an experimental methodology. We hope to clarify the relationship between computers and problem-solving, and to compare the differences between traditional materials and computers when used to discover problems.

summary	Technically-oriented architectural spaces today are getting complicated because the building contains a number of electronic facilities and complex structures. Furthermore, the advent of the ubiquitous environment enabled the building to provide various services to users and accelerated the importance of architectural visualization as problem-solving and communicating tools. It is recommended that architectural visualization has been more intuitive and effective to support the design decision and collaboration. In this manner, this paper intends to define the role of current architectural visualization with considerations of previous research and related works in the practical field and proposes the appropriate method of architectural visualization. Also, in order to evaluate our idea, we recommend a prototype system based on dynamic and semantic representation with the avatar. It is a kind of simulator for the design of ubiquitous smart space and can deliver to users the better comprehension in how technological oriented space will be constructed and utilized.

title	A framework for distributed agent-based engineering design support
source	Automation in Construction 10 (5) (2001) pp. 631-637
summary	Concurrent engineering draws together team working and cooperation, with the aim of reducing the need for costly design modifications in the later stages of design and product development. However, the complexities arising in the process of design, in general, defy formal analysis and computational support is required. In providing intelligent computational support for concurrent engineering, a combination of various problem-solving strategies may be required for complex design situations. It is proposed that an appropriate model for such provision is in the form of a set of interacting autonomous intelligent agents, possessing different problem-solving capabilities and differing degrees of intelligence. The requirements for such agent-based design support are discussed and possibilities for its realisation, with the aid of Web technology, in a distributed design environment are explored.

title	Capturing design knowledge in formal concept definitions
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	For support of creativity in architectural design, design systems must be provided with information models that are flexible enough to follow the dynamic way of designers in handling early design information. This paper discusses a framework for information modelling using Features that answers this need. One of the characteristics of the framework is that designers can define the formalisation of their own design concepts into types of Features. The definition of these Feature Types can be done in different manners; three scenarios for this procedure are presented and discussed.

summary	Collaboration in design can take place in a physical, social space, in a distributed or virtual environment, or in a combination of both. Design teams use a range of ICT means to support both synchronous and asynchronous communication. While these tools are designed to facilitate collaboration, the collaboration process still requires planning and organisation in a social context, which are activities that students and professionals need to learn. In current practice there is a need for designers and design managers who have the competences to collaborate in design and to organise distributed collaboration processes. At the department of Architecture, Building, and Planning at Eindhoven University of Technology, we have developed a course on Collaborative Design in the Master of Science curriculum. This course addresses both the organisational, social, and technical issues of collaboration in design. The paper introduces the objectives and educational methods used in this course. It describes the experiences of both teachers and students that were gained now that the course was taught in three subsequent years.

summary	The purpose of this paper is to present the characteristics of laser scanning technology, based on two examples for the modeling at the reconstruction of the Golgotha site in Jerusalem and the ancient Stoa of Eumenes II, located at the South Slope of the Athens Acropolis. Terrestrial 3D laser scanning is a new methodology for three dimensional object modeling. Especially, the reconstruction of the ancient Stoa of Eumenes II comprises one of the most important restoration programs of the Greek Ministry of Culture. This paper will focus on the main steps of the laser scanning processing chain, starting from the acquisition of the data and ending with the evaluation of the 3D models.

summary	About the glocal very much has been said by Michael Porter . According to this author, in some countries there is a competitive advantage, in some industry . It is explained by a « diamond » with four facets : competition and rivalry inside the country, factors endowment, demand, related industries (providers, firms selling components etc … ) . The competitive advantage appears when the facets are efficient, and stimulating one another, in a country. Then the firms of this country invest abroad, to benefit from thecompetitive advantage, grabing market shares and making profits . The country itself is the place of the competitive advantage . Theinternational market is the place of the challenge, where the result of the competition appears .

title	Parallel Modeling: Addressing the Issues of Creative Designing in CAD Environments II. Special Applications
source	Proceedings of the Fifth International Conference on Human-Computer Interaction 1993 v.1 pp. 249-254
summary	We postulate that Industrial Designers, in general, solve a given problem by generating a series of proposed solutions to that problem, each proposal, in theory, helps the designer to converge on the ideal solution. Any number of solutions may be under continuous development at any one time and any previous solutions should always be available for appraisal and viewing. The single modeling environment provided in traditional Computer Aided Design (CAD) systems does not support this practice. Thus, CAD systems are primarily used to address the final phases of the design process, such as analysis, visualisation and detailing. This is surely not utilising the full potential of such a powerful design tool. In an attempt to develop a less restrictive working practice for CAD users, we consider a parallel modeling approach. This solution allows the simultaneous development, design and review of a number of computer based solutions.
