summary The architectural design requires collaboration among various participants, such as architects, clients, engineers in the stages of the design process. The Sasada laboratory has been involved in the various collaborative architectural design projects. The authors found several important issues in the process of those projects. Firstly, the presentation data is composed of different kinds of data such as documents, computer generated still images, movies and 3D objects. The participants involved in those projects need to access these data as necessary. Secondly, it is virtually impossible for all participants to attend at the same time and place. Therefore, computer networked collaborative design work is essential, in particular, for an international project and for a complex architectural design project.

title Sustainable Design Framework for the Anthropocene - Preliminary research of integrating the urban data with building information

summary In terms of the efficiency and informatization in the architecture and construction industry, the Fourth Industrial Revolution presents positive aspects of technological development, but we need to discuss the expanded concept, the Anthropocene. The era of the human-made environment having a powerful influence on the global system is called Anthropocene. Since the 1950s, many indicators representing human activity and earth system have shown the 'Great acceleration'. Currently, lots of urban data including building information, construction waste, and GHG emission ratio is indicating how much the urban area was contaminated with artifacts. So, the integrated planning and design approach are needed for sustainable design with data integration. This paper examines the GIS, LCA and BIM tools focusing on building information and environmental load. With the literature review, the computational system for sustainable design is demonstrated to integrate into one holistic framework for the Anthropocene. There were some limitations that data was simplified during the statistical processing, and the framework has limitations that must be demonstrated by actual data in the future. However, this could be an early approach to integrating geospatial and environmental analysis with the design framework. And it can be applied to another urban area for sustainable urban models for the Anthropocene

title Design Adaptation for Handling Design Failures
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 567-576
summary This research deals with two important issues in Case-based Design (CBD): a structure of design cases and a process of design adaptation for handling design failures. The structure of design cases involves problem situation, design specification, design tasks, design solutions, causal explanation, past design failures as well as design performance. It has been noticed that how to represent a structure of design cases and how it can be used in actual a process of design adaptation process are important in Case-based Design. Adaptation process in Case-based Design is also critcial, especially in handling design failures. The description and the analysis of design adaptation process in the context of Case-based Design paradigm is the major focus of this research. A model of casual explanation is presented as an useful tool for identifying sources of design failures. For efficiently handling design failures based on causal explanation, it is essential to characterize various design failures and to devise an adequate structure of adaptation process. Applicability of adaptation process is demonstrated in an exemplary kitchen layout.

summary Graduate Institute of Architecture, National Chiao Tung University, Hsinchu, 30050, TAIWAN The adaptation of the word cyberspace (Gibson, 1984) following the emergence of the World Wide Web Internet not only succinctly revolutionized the correlation of time and space but also poised to challenge how we view the existing spatial concept. This research tries to use protocol analysis to examine text-based cyberspace, such as bulletin board, chart rooms and so forth, and the objective of this research is to realize the spatiality of cyberspace through the cognitive point of view, and to compare the differences of the definitions and perception ways of spatiality between people with general domain and in design fields. Finally, we validate the existence of cyberspace, where the process not only allows further categorization of spatial elements concluded from the earlier study, but discover that varied backgrounds can affect how a user defines and perceives cyberspace (Strate, 1999).

summary Graduate Institute of Architecture, National Chiao Tung University, Hsinchu 30050, Taiwan The evolution of design media has kept a close relationship with the development of design methods in the history. Nowadays, different computer media have been used in different stages of the design process. It is to believe that computer media have great impact on the design process and methods. The objective of this paper is to realize the design process and methods when designers use computer modeling to tackle an architectural design problem. The methodologies are non- participant observation and retrospection. The findings of this research prove that media does contribute to the changes in design process and methods. Not only does its conclusion help to better understand properties of different media, but also benefit the development of computer media.

summary Korean traditional structure is constructed as prefabrication jointed in largely characterized by its unique components under the specific rules of assembly and proportion. This point is a double-edges sword. Because, while various shapes and sizes of components based upon an objected-oriented form appear the potential possibility of producing changeable prototypes to build up, these various characters of components and several jointed methods has made difficulties to handle. Accordingly, an automatic 3D modeling algorithm is focused on the methodology of changeable prototypes of Korean Traditional architecture keeping traditional jointed methods with setting various characters of components

summary This paper describes the color design process of the house in the village. The color design process proposed in this paper constitutes design stages such as color selection, color application, and color design analysis and evaluation. In the color selection step, a method of arranging colors using a color pallet or a color scheme is described. The color application stage includes the process of creating a village color design alternatives by specifying the color information of the hue, value, and saturation based on the BIM model. The color analysis stage is to numerically identify the color design attributes of the generated color design alternatives. The reason for color analysis and evaluation is to produce various design alternatives with the color harmony and improve the quality of the design.

summary Color selection plays a vitally important role in creating impressions of individuals or companies because colors have sensibility aspects and relate to some images or associations. Based on both the theory of color harmony and the sensibility ergonomics, some quantitative and systematic researches on the color image have been developed. In this paper, we suggest a color coordinate system that supports the color analysis and the color harmony functions using color images, which can be captured by corresponding adjective words. We focus on a system prototype for interior design domain to exemplify our concepts in this paper, even though this system can be applied for all design domains.

title iSphere:A free-hand 3D modeling interface
source International Journal of Architectural Computing vol. 4 - no. 1, 19-31
summary Making 3D models should be an easy and intuitive task like free-hand sketching. This paper presents iSphere, a 24 degree of freedom 3D input device. iSphere is a dodecahedron embedded with 12 capacitive sensors for pulling-out and pressing-in manipulation on 12 control points of 3D geometries. It exhibits a conceptual 3D modeling approach for saving mental loads of low-level commands. Using analog inputs of 3D manipulation, designers are able to have high-level modeling concepts like pushing or pulling 3D surfaces. Our experiment shows that iSphere saved steps in the selection of control points in the review of menus and leading to a clearer focus on what to build instead of how to build it. Novices saved significant time learning 3D manipulation by using iSphere to making conceptual models. However, one tradeoff of the iSphere is its lack of fidelity in its analog input mechanism.

summary This paper presents a visibility analysis for 3D urban environments and its possible applications for urban design. This multi-view visibility analysis tool was generated by 3D isovist in Grasshopper, Rhino. The advantage of this analysis tool is that it can be compared within the measurement area. In addition, setting a visual object different from the existing isovist. The visual object is a landmark of a city space, such as landscape or object. First, the application experimented on the relevance between the calculation time and precision by this analysis tool. Based on the results of this experiment, it applied it to an actual part of an urban space. The multi-view visibility includes confirming the possibility of a comprehensive evaluation on the urban redevelopment and change of the view caused by the building layout plan - by numerical analysis showing the visual characteristics of the area while using 3D isovist theory. The practically applied area is Shinkiba, which is a part of Tokyo's landfill site; and while using the calculated data, multi-view visibility of each plan in the simulation of the visibility map is compared and evaluated.

summary In this paper, we present a user-friendly and practical method for seamless integration of computergeneratedimages (CG) with real photographs and video. In general, such seamless integration isextremely difficult and requires recovery of real-world information to simulate the same environment forboth CG and real objects. This real-world information includes camera positions and parameters,shapes, material properties, and motion of real objects. Among these, one of the most important islighting.Image-based lighting that is developed to recover illumination information of the real world fromphotographs has recently become popular in computer graphics. In this paper we present a practicalimage-based lighting method that is based on a simple and easily constructable device: a square platewith a cylindrical stick. We have developed a user-guided system to approximately recover illuminationinformation (i.e. orientations, colors, and intensities of light sources) from a photograph of this device.Our approach also helps to recover surface colors of real objects based on reconstructed lightinginformation.

summary Intelligent environments are buildings and other settings that can recognize the changing needs of their users and/or the changing nature of their context, and respond to them by adjusting some key environmental parameters (temperature, light, sound, furnishings, etc.). Unlike the currently common approach, which is based on systems theory (i.e., adjusting the parameters of the environment to match some pre-defined use profile), the approach proposed in this paper is based on dynamic, collaborative design: it views the (built) environment as comprised of multiple independent object-agents, each of which is responsible for one small aspect of the environment. Each can sense the immediate changes pertaining to its domain of responsibility, and propose corrective measures, which are negotiated with other agents to form a collective response. The paper hypothesizes that such an approach can be made more context-sensitive and dynamic, is easily scaleable, and can respond to the needs of multiple different users of the environment at the same time. The paper presents the rationale for developing the multi-agent approach, its hypothetical implementation, and its application to hypothetical case studies.

summary The notion of globalisation has become widely spread in various fields, and accordingly, it is increasingly more important to take account of indigenous culture characteristics in each field. An as- pect of achieving globalisation, globalization with local consideration, is to consider the difference of colour usage between distinct cultures. This study suggests an approach to investigate the colour difference between eastern and western cultures with the case analysis of build- ing fac?ade colours in Disneyland Paris and Tokyo Disneyland. We an- alysed cultural colour usage characteristics and derived tendencies for both Paris and Tokyo Disneyland building fac?ade colours. To do this, we use image based k-means clustering algorithm and CIELAB colour space distances to explore colour characteristics. Our analysis indi- cates an overall colour usage tendency that Paris uses more green and bluish colours and Tokyo uses more red and yellowish colours for building fac?ades, based on CIELAB colour space values. The major motivation of this paper was to reflect the atmosphere and the mood of the space that can be easily felt but not readily expressible into a cultural colour palette. Eventually, by finding the characteristics of perceived colours, we hope to create a colour recommendation system for different cultures based on cultural clues.

summary The “Case Studies in Architecture” phase of a course in architectural design includes in-depth comparisons and analyses of architectural precedents. However, with the large number of cases now readily available, Web searching and navigation is a time-consuming, low precision activity. In the work described in this paper, we built eCAADe, an educational commendation system for the adaptive semantic Web to allow students to query and retrieve semantically for architectural cases during the case study phase of an architectural design process. In our suggested system, we built a Semantic Web for design knowledge representation to make query and retrieval efficient. We also applied a hybrid recommendation mechanism, which is combining both content-based filtering and collaborative filtering to help for students to find relevant cases more efficient and precise with their preferences. We illustrate our concepts with several concrete examples.

Computation of neural networks systems, as a result and the difference between human designers and computer, can be discussed too. Also, since the work of Neo-Plasticism Mondrian influences contemporary architecture design, industrial design, andvisual design directly or indirectly, floorplans of architect John Hejduk’s works were taken as an example to discuss the application of Neural networkss in the design field.

title Developing the Reinforcement-Learning Child Agents for Measuring Play and Learning Performance in Kindergarten Design

doi https://doi.org/10.52842/conf.ecaade.2023.1.069
summary Although kindergarten design requires promoting play behaviours related to physical and social development and ensuring safety of children to support a child-oriented design, the systemic evaluation of design performance remains challenging because of the children’s dynamic play behaviours. As one solution, agent-based simulations have been applied in the design field, but there are limitations in reflecting children’s behavioural richness. To overcome this shortcoming, this study developed reinforcement learning (RL) child agents to compute the dynamic play behaviours associated with physical and social development. Several iterations were conducted to implement the RL agents’ play behaviours, and the results were incorporated into the simulation. To validate the play behaviour model, we conducted a case analysis with authentic and unbuilt kindergarten designs and measured the quantifiable design performance in terms of physical and social play behaviours and safety. The results indicated that the RL child agents enabled a holistic analysis and the calculation of generative behavioural responses, depending on physical variations. By facilitating an unknown design affordance, the RL-powered simulation model is expected to provide data-driven evidence to support a child-oriented design.
