title Digital CADCAM Pedagogy Model: Intelligent Inquiry Education
source Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 458-463

summary Prototype manufacturing as an educational tool has been very successful at the college level in architecture and engineering design. This paper discusses an innovative inquiry-based learning approach rather than the problem-based learning models commonly utilized by other similar programs. For example, several research-funded technology projects (e.g., Cappelleri et al. 2007) look at involving students in problem-based learning exercises (e.g., building robots); however, these exercises (while providing valuable experiences) have predetermined outcomes ingrained by the teachers, the project structure, and the components used to construct the devices. Therefore, inquisitive and creative problem solving is limited to the “kit-of-parts” in their approach to solving the problem. The inquiry-based CADCAM pedagogy model is more concerned with the process of solving a problem through the vehicle of prototyping than with the specificity of the design project itself. This approach has great potential. First, the need to solve the problem drives learning on multiple levels, integrating interdisciplinary ideas into the problem and solution. Second, the problem interlocks disciplines through inquiry knowledge building in team exercises. Finally, it encourages diversity and flexibility by allowing students to look at problems from multiples perspectives and points of view.

title Creating Alternative Futures
source New York: Putnam
summary Creating Alternative Futures has pioneered many debates on how to guide industrial societies on healthier paths toward more equitable, ecologically sustainable human development. Henderson explains how GNP distorts the goal of human development worldwide. She points out misleading assumptions and a redefinition of health, wealth, and progress for humanity's long-term survival. The book predicts the sweep of democratization and the new "third sector" of grassroots globalists.

title A methodological approach to object modelling in the architectural designprocess
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary The paper describes a first prototype constructed in search for a central object model. It presents all possible data, concepts and operations concerning the architectural design process in the early phases.A central model of the process of design is essential: going from one design phase into another, the model describes geometrical shapes, abstract concepts like space and activity, concrete physical building elements and the basic operations all these entities undertake. Emphasis is put on combining all these different viewpoints, thus enabling the designer to use a broad range of design strategies. The aim is to help him and not steer or even hamper his creative process. Information necessary toassist the user of the system concerning energy calculation, stability checks etc can be extracted. By means of appropriate interfaces not only those tests built on top of the system but also existing software packages can make use of the model’s object structure. The implemented object model is one of the cornerstones of the IDEA+ project, aiming to provide an Integrated Design Environment for Architecture.

summary The course on CAAD at the KU Leuven is part of the course on design methodology and theory from which it is the most recent and natural extension. Attached to this course a series of assignments has been developed which bring the students in 45 hours to a non-trivial level of acquaintance with CAAD. Our assignments are primarily directed towards practice. They are built on top of AutoCAD to which we have added in-house developments in order to focus on specific pedagogical goals within a very limited time. After a general introduction on Windows (file management) and AutoCAD (basics) students make the following assignments (main pedagogical goals in between brackets). colophon (working with blocks), detail (2D-drawing, hatching, editing), facade design using a built-in system of proportion (slides, scriptfile), extraction (linking alphanumerical and graphical entities), container (level of detail, icon menus, viewports), surface modelling (modelling 3D-objects with surfaces), fractal tree (recursion in Autolisp), solid modelling (Leicester engineering building), lighting (integration of drawing and computation of illumination levels), pressure lines in an arc (interactive design of an arc), demos. The paper presents and comments these assignments and shows results from the last 2 years.

title A Core Object Model for Architectural Design
source Katholieke Universiteit Leuven
summary A core object model apt to describe architectural objects and their functionality is one of the keystones to an integrated digital design environment for architecture. The object model presented in this thesis is based on a conceptual framework for computer aided architectural design (CAAD) and aims to assist the architect designer right from the early stages in the design process. For its development the object-oriented analysis method MERODE (Model-based Existence-dependency Relationship Object-oriented Development) is used. After a survey on the role of computers in the architectural design process and on particular Product Modelling initiatives, the model is elaborated in two phases: the enterprise-modelling phase and the higher functionality-modelling phase. Actual design cases and test implementations help to establish the conceptual model and illustrate its concepts. The appendices provide a detailed description of both the object model and one of the case studies. The architect’s point of view and the specific nature of the architectural design process are the basic considerations, thus leading to a unique model that hopes to make a valuable contribution to the research area of integrated design environments.

summary The course on CAAD at the K.U. Leuven is part of the course on design methodology and theory from which it is the most recent and natural extension. Attached to this course a series of assignments has been developed which bring the students in 45 hours to a non-trivial level of acquaintance with CAAD. Rather then mimic the traditional pencil- and paper approach, the exercises encourage students to explore additional design opportunities that a drawing board cannot offer. In this way, the practical part goes beyond a mere preparation for practice. The assignments are built on top of AutoCAD to which we have added in-house developments in order to focus on specific educational goals within a very limited time. The paper presents and comments these assignments and shows results from the last 2 years.

title Setting objects to work: adding functionality to an architectural object model
source Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary Several research initiatives in the field of product modelling have produced static descriptions of the architectural and geometrical objects capable of describing architectural design projects. Less attention is paid to the development phase in which these static models are transformed into workable architectural design environments. In the context of the IDEA+ research project (Integrated Design Environment for Architectural Design), we use the object-oriented analysis method MERODE to develop and describe both an enterprise (or product) model and a functionality model. On the one hand, the enterprise model defines the architectural and geometrical objects, their methods and their relation with other objects. On the other hand, the functionality model organizes the functionality objects – ranging from single-event objects to complex-workflow objects – in a layered and easily expandable system. The functionality model is created on top of the enterprise model and closes the gap between the static enterprise model and the dynamic design environment as a whole. After a short introduction of the envisaged design environment and its underlying enterprise model, the paper will concentrate on the presentation of the higher-level functionality model. Elaborated examples of functionality objects on the different levels will clarify its concepts and proof its feasibility.

title A Virtual Reality Window View Evaluation Tool for Shading Devices and Exterior Landscape Design
source Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
doi https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_14
summary The window view is an important part of the daylighting design. The current window view analysis based on daylighting metrics does not respond well to user preferences. This study uses an office with a courtyard in Berkeley, CA, USA, as a case study to create a virtual reality-based window view evaluation tool and workflow to analyze the impact of different types of shading devices and different levels of exterior landscapes on user perception. This tool combines quantitative data based on daylighting metrics and users’ subjective and physical responses with qualitative analysis based on user feedback and preferences. A two-way ANOVA was conducted in the study to demonstrate that the independent and interactive impacts of shading devices and exterior landscapes on user perception and satisfaction. The results show that users prefer shading types that block less of window views even though they may cause a higher probability of glare. Besides, advanced landscapes tend to enhance user satisfaction with shading devices. This new window evaluation method will help architects make more comprehensive decisions in shading device type selection and exterior landscape design.

summary Several product-modelling initiatives have produced static descriptions of the architectural and geometrical objects capable of describing architectural design projects. Less attention is paid to the development phase in which these static models are transformed into workable architectural design environments. In the context of the IDEA+ research project (Integrated Design Environment for Architectural Design) emphasis lies on the systematic development of both phases. The result is an analysis model that consists of two submodels. On the one hand, the enterprise model defines the architectural and geometrical objects, their methods and their relation with other objects. On the other hand, the functionality model organises the functionality objects - ranging from single-event objects to complex-workflow objects - in a layered and easily expandable system. As such, it closes the gap between the static enterprise model and the dynamic design environment as a whole.

summary The IDEA+ project aims at developing an Integrated Design Environment for Architect designers, in which design tools and computational tests make use of one and the same core building description. Such a description must be apt to describe architecture in a full-fledged way. Hereto, the authors have put the IDEA+ model to the test with actual design cases. These cases have been used to test isolated design concepts and to mimic the global design process.

title Digital Reconstruction of Medieval Chinese Cities
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 529-540
summary The study and teaching of Chinese urban planning particularly of the earlier periods is heavily handicapped by the lack of pictorial or physical evidence. This is mainly due to the perishable nature of Chinese traditional construction which depended heavily on timber for both its structure and infill. Large architectural complexes were torched during wars and entire cities destroyed during dynastic upheavals. The Tang (618-906) capital of Chang'an is a classic example. Perhaps the foremost city in the world during the seventh and eighth centuries, it was reduced to wasteland by the beginning of the tenth century. The city now lies a little below the modem city of Xi'an, which occupies only a fraction of the Tang capital. The Northern Song (961-1127) capital, Kaifeng, also suffered similar fate when warfare and natural disasters eradicated the Song city. The ruins are buried five to twelve meters beneath present day Kaifeng. The earliest surviving imperial city is Ming (1368-1644) Beijing. By comparison, there are still substantial ruins from Athens and Rome in the Western world. The study of Chinese urban planning and the understanding of past urban structures are important as the influence of these urban structures are still discernible in historic Chinese cities today. While traditional Chinese architecture is perishable, traditional urban planning principles leaves their imprints much longer despite the frequent replacement of the physical urban fabric.

title Petri net as a formalism to assist process improvement in the construction industry
source Automation in Construction 7 (4) (1998) pp. 349-356
summary One major reason that hinders the implementation of process improvement principles in the construction industry is the lack of a powerful formalism to model and analyze the existing and new workflow processes. This paper proposes a framework which is based on the use of Petri nets for modeling and analyzing workflow processes in construction. The paper starts with an overview of current developments in the Petri nets theory. The paper then presents an example to demonstrate how to use the Petri net based framework to assist important steps of process improvement.

summary The laborious creation of digital images could soon be a thing of the past. Text-to-image software generates images from text descriptions through artificial intelligence, the AI can map entirely new concepts and create images in a variety of artistic styles. Existing text-to-image software is already publicly available, but does it live up to its promise, and can it be more useful to architects in their search for inspiration than previous software that uses visual search to display images? In this paper, we address the opportunities and problems of text-to-image software. To answer our question, we use a key study, this is divided into two user groups. The subjects of group A are to use DALL·E 2 to search for inspiration for a design whose task is: Design a museum with a boat dock. The same design task is also given to the subjects of group B, with the difference that they are to use Pinterest to find inspiration.We will then contrast the results of these surveys. We will document the differences of the user experience and the output of DALL·E 2 to Pinterest as well as about advantages and disadvantages of DALL·E 2 and possible future developments, and application areas of text-to-image software.

title Communicating Concepts for Shared Understanding: A Multi-Agent Approach

summary Capturing and sharing design concepts is necessary if we want to support the design process by means of Information & Communication Technology (ICT). Standardized concepts are important for support at the end of the design process when designs need to conform to set standards and norms, and in order to enable communication, but are less useful in the early design stages. We propose an approach that takes into account a more developmental attitude that will be better suited for design support and the sharing of design concepts. In this approach, design concepts are formalised by means of a technology called concept modelling. Capturing and exchange of concepts are based on a multi-agent approach. The whole of concepts that are used in a domain or for a design task can be considered a design ontology. In this paper we outline the motivations for the research, outline the basic approach in the research work, and identify the major challenges and research problems that need to be tackled.

summary The problem of complexity underlies all design problems. With the advent of CAD however, our ability to truly represent complexity has increased considerably. Following the four waves of design methodology as distinguished by Cross (1984), we see changing architectural design attitudes with respect to complexity. Rather than viewing it as problematic issue, designers such as Koolhaas, van Berkel, Lynn, and Franke embrace complexity and make it a focus in their design work. The computer is an indispensable instrument in this approach. The paper discusses the current state of the art in architectural design positions on complexity and CAAD, and reflects in particular on the role of design representations in this discussion. It is advanced that a number of recent developments are based on an intensified use of design representations such as schema’s, diagrams, and interactive modelling techniques. Within the field of possibilities in this field, the authors discuss Feature-Based Modelling (FBM) as a formalism to represent knowledge of the design. It is demonstrated how the FBM approach can be used to describe graphic representations as used in design, and how other levels and kinds of design knowledge can be incorporated, in particular the less definite qualitative information in the early design phase. The discussion section concludes with an extrapolation of the current role of design representation in the design process, and advances a few positions on the advantage and disadvantage of this role in architectural design.

title TetraScript: A Responsive Pavilion, From Generative Design to Automation
source International Journal of Architectural Computing vol. 10 - no. 1, 87-104
summary This research is part of a broader investigation into the use of digital technologies in the Architecture, Engineering and Construction (AEC) sector. The intention is to improve the ability of buildings to respond to context by proposing a skylight system that can adjust to external environmental conditions and internal functional demands. We call this responsive ability customisation. The proposed skylight system can adapt to different geometries, uses, locations, times of day and other contextual conditions. Customisation can be achieved by static and dynamic processes. Static customisation is achieved during the design process by selecting the form and size of the building, as well as the number, arrangement and size of the skylights, among other features. Dynamic customisation is accomplished after construction by changing the skylight aperture in real-time to control interior conditions. This paper focuses on the static process to find an adequate skylight configuration for a case-study pavilion.

summary Responsive architecture is often considered as one that merely adapts to change. This reflects its limited and still incipient application in architecture. Due to the current resource crisis, systemic building management is essential. This article argues that there are no established processes for creating and managing responsive architecture. To establish a foundation in this area, it claims that it is necessary to deepen knowledge about systems, computation, mathematics, biology and robotics. Despite being a vast subject, it proposes a state of the art of the systems, investigating how to operate them. A method for generating responsive systems is tested and implemented in a practical case. Two methods of adaptation are proposed and tested: static and dynamic adaptation. These methods reinforce the point that responsive architecture can use not only active mechanisms, but also passive methods embedded in its form as information. The research concludes that information management is critical to define what is designated in software engineering as architecture of the system. Thus, it suggests that it is necessary to define meta-systems and to define their methods to support the generation, fabrication, construction and operation of responsive systems.

summary The craft of complex artefacts, questioning technological changes and reflecting social and cultural transformation used to be a common attitude in traditional artisans of the pre industrialized society. Traditional craftsman developed special knowledge and skills, implementing their own tools and techniques. After the industrial revolution, the main focus shifted to mass production, and the personalization of artefacts became labour intensive and more expensive. Simultaneously, with technical specialization and the fragmentation of knowledge, the designer’s, builder’s and manufacturer’s approach became more segregated. Currently, information technologies offer new opportunities to the craft of complex objects. The integration of digital process from conception to fabrication, can transform this situation, and as a result personalization is more affordable. Nevertheless, the introduction of these new techniques or tools is lacking a poetic synthesis for the use of technology, and the social and cultural implications that may result of this use. A competition for a public installation was an opportunity to use digital tools to conceive, manufacture and construct a complex structure with a small budget that would be impossible to attain using only traditional tools. At the same time, this project - genetic landscape- could be seen as a metaphor, alluding to the technological interference on the process of creating a new life, or a second nature.

summary The fourth Industrial Revolution is characterised by the computational fusion of physical, digital and biological systems. Increasing information in terms of size, speed and scope exponentially. This fusion requires improved, if not new, tools and methods to deal with complexity and information processing. By opening Generative Systems to interact with the context, we believe that they can develop solutions that are more adequate for our time. This research began with a literature review about generative systems and their application to solve problems. We then selected the tools, Cellular Automata, L-Systems, Genetic Algorithms and Shape Grammar, and thought about how to translate these original mathematical tools to specific design situations. We tested the application of these tools and methods in a workshop, implementing recursive loops to open these techniques to interference. Analysing the empirical results made us revise our design thinking, relying on the study of complexity to understand how these techniques can be more context-aware, so we can make design evolve. Finally, we present a comparative framework analyses that interlaces techniques and methods, so in the future we can merge physical, digital and biological information.
