title Ceramic Components - Computational Design for Bespoke Robotic 3D Printing on Curved Support
source Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 71-78
summary Additive manufacturing enables the fabrication of affordable customisation of construction elements. This paper presents a computational design method developed for 3D printing of unique interlocking ceramic components, which assemble into segmented columns. The fabrication method is ceramic-paste extrusion, robotically placed on semi-cylindrical molds. Material system and fabrication setup contribute to the development of an integrated generative system which includes overall design, assembly logic and printing tool-path. By contextualizing clay extrusion and identifying challenges in bespoke tool-path generation, this paper discusses detailing opportunities in digital fabrication. Finally, it identifies future directions of research in extrusion-based printing.

title Assesing Strategy Questionnaire for Architectural Styles of Designing (ASQ-FASD)
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary In this paper the first results will be discussed that were obtained by the Assessing Strategy Questionnaire For Architectural Styles of Designing (ASQ-FASD). This questionnaire was developed specifically for the assessment of architectural design strategies. The construction of the questionnaire will be discussed in light of previous protocol research on strategic styles of designing. With this questionnaire, we developed a tool to assess an architects design strategy in a faster, easier and more reliable way than used to be the case with conventional protocol studies and other knowledge eliciting techniques like Card Sorting, and Repertory Grid. This questionnairewas submitted in a pilot study to 10 experienced Dutch architects. R.esults show that architects do indeed have preferences for different design situations. Moreover results indicate that they havea preference with respect to their responses within such specific situations. Though the generalizability coefficient was calculated for no more than 10 architects with a value of .57 (generalizing across situations), we feel that this is reason enough to assume that the questionnaire can be used to assess design strategies of architects. These results will be discussed with respect to the development of new design and decision support tools. The fact that designers have preferences for specific design problems and that they respond differently should be considered in the implementation of user interfaces and data base technology where possible.

title Understanding Heat Transfer Performance for Designing Better Façades
source ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 71-78
summary This early research focuses on the design of building façades to mediate external and internal thermal conditions. It explores new workflow for accessible feedback into the early design of façade systems. Specifically, this research aims to explore the level of corroboration or the gap between predictions of thermal behavior using digital modeling and simulation, and the empirical measurement of thermal behavior in physical analog models for façade design.

summary This paper compares the musical and architectural languages exploring the similarities between works related to Twelve-tone music and Descontruction. To do this, first looks at Opus 27 by Anton Webern whose goal was to explore the spatiality in the context of sound perception by using a topology based on a square matrix of twelve rows and columns. Next, compares these procedures to those adopted by Peter Eisenman to design the conceptual model Guardiola House (1988), demonstrating the affinity between spatial and temporal constructions in the works of these two authors.

title Reconnecting [Conference Proceedings]
source ACADIA Conference Proceedings / ISBN 1-880250-03-9 / Washington University (Saint Louis / USA) 1994, 232 p.
summary This book captures and binds disparate streams of information in a single volume and attempts to reconnect us to the experience of architecture through holding a book in our hands. Just as architecture uses the connections among the dissimilar as the sites for design intervention and invention, the content of this book attempts to connect the objective processes that are characteristic of computers with the subjective processes that are characteristic of creativity. The chosen format juxtaposes technical work in the first half with pedagogical explorations in the second half. By recognizing their differences and separating them from each other, the process of reconnecting can occur. Within both the technical and pedagogical sections, a continuous stream of information connects the papers across the bottom of the page. Against the technical papers, we have placed the keynote paper by Professor Paul Laseau. Against the pedagogical papers, we have placed a drawing done by Trent Tesch that is a visual interpretation of cyberspace based on the novel, Neuromancer, by William Gibson. While turning these pages, consider the accidents that take place through the juxtaposition of streams of thought sharing a single page.

title Component-Based, Three-Dimensional "Working Drawings"
source Education and Practice: The Critical Interface [ACADIA Conference Proceedings / ISBN 1-880250-02-0] Texas (Texas / USA) 1993, pp. 141-151
summary It is now possible to communicate technical information about a building utilizing accurate threedimensional computer modeling of component assemblies of an entire building for the production of an alternative set of "working drawings." Most assembly illustrations and final appearance can be presented as output from the computer model. The use of these three-dimensional images in the practice of architecture may improve communication between the members of the building design team and, therefore, may improve the overall design integration of the various systems in a building.

Additionally, this type of component model construction for the production of technical drawings offers a unique bridge over the gap between the practice of architecture and the teaching of architecture. Rather than teaching students how to "do working drawings," something all practitioners wish the academic institutions did, students would develop the ability to design, integrate, and construct complex three-dimensional assemblies and present them in a variety of ways using the standard sections, layers, view, etc. inherent in any reasonable threedimensional computer based modeling system.

summary This works in progress paper describes the development of an alternative method for teaching building technology using the composite sketch concept borrowed from police forensics. The composite sketch utilizes individual components and assemblies of construction in various combinations to explore the design implications of materials and connections on form and surface. To enhance the usefulness of the composite sketch, in-depth case studies of specific buildings are linked to the digital assemblies of the composite sketch so that students can see the basic concepts in actual buildings. The project currently models more than 500 combinations of components and includes approximately 200 catalogued images of buildings under construction.

title Component Based Computer Aided Learning for Students of Architecture and Civil Engineering
source New Ideas and Directions for the 1990’s [ACADIA Conference Proceedings] Gainsville (Florida - USA) 27-29 October 1989, pp. 193-208
summary The paper describes the methodology and the current efforts to develop an interdisciplinary computer aided learning system for architects and civil engineers. The system being developed incorporates a component oriented relational database with an existing interactive 3-dimensional modeling system developed in the School of Architecture and Planning at SUNY Buffalo. The software will be used in existing courses in architecture and civil engineering as a teaching aid to help students understand the complex 3-dimensional interrelationships of structural components. Initial implementation has focused on the modeling of the components and assemblies for a lowrise steel frame structure. Current implementation efforts are focusing on the capability to view connections in various ways including the ability to "explode" a connection to better understand the sequence of construction and load paths. Appropriate codes, limit states of failure and specific data will be linked to each specific component in an expert system shell so that the system can offer feedback about a student generated connection and perhaps offer other possible connections a library of standard connections. Future expansion of the system will include adding other "systems" of a building, such as mechanical, electrical, plumbing, enclosure etc., to help students visualize the integration of the various parts.

title Building Representation within a Component Based Paradigm
source From Research to Practice [ACADIA Conference Proceedings] Big Sky (Montana - USA) 4-6 October 1990, pp. 117-127
summary This paper questions the use of a 2-dimensional medium to convey 3-dimensional information about design intent and proposes a computer-aided paradigm that could radically alter the way in which buildings are designed and built. The paradigm is centered about the accurate and rational representation (Rush, 86) of each individual component that makes up a building in a single, shared, computer based model. The single model approach couples the accurate physical representation of components with the accurate representation of technical information and knowledge about the assemblies of building components. It is anticipated that implementation of this approach will result in fewer communication problems that currently plague the fragmented process of practicing in the professions of architecture and engineering. The paper introduces the basic concepts within the paradigm and focuses on the development of intuitive, reasoning about the component-based design suitable for incorporation in a computer-aided setting.

title Component-Based Spatial Reasoning
source Mission - Method - Madness [ACADIA Conference Proceedings / ISBN 1-880250-01-2] 1992, pp. 103-111
summary The design process and ordering of individual components through which architecture is realized relies on the use of abstract "models" to represent a proposed design. The emergence and use of these abstract "models" for building representation has a long history and tradition in the field of architecture. Models have been made and continue to be made for the patron, occasionally the public, and as a guide for the builders. Models have also been described as a means to reflect on the design and to allow the design to be in dialogue with the creator.

The term "model" in the above paragraph has been used in various ways and in this context is defined as any representation through which design intent is expressed. This includes accurate/ rational or abstract drawings (2- dimensional and 3-dimensional), physical models (realistic and abstract) and computer models (solid, void and virtual reality). The various models that fall within the categories above have been derived from the need to "view" the proposed design in various ways in order to support intuitive reasoning about the proposal and for evaluation purposes. For example, a 2-dimensional drawing of a floor plan is well suited to support reasoning about spatial relationships and circulation patterns while scaled 3-dimensional models facilitate reasoning about overall form, volume, light, massing etc. However, the common denominator of all architectural design projects (if the intent is to construct them in actual scale, physical form) are the discrete building elements from which the design will be constructed. It is proposed that a single computational model representing individual components supports all of the above "models" and facilitates "viewing"' the design according to the frame of reference of the viewer.

Furthermore, it is the position of the authors that all reasoning stems from this rudimentary level of modeling individual components.

The concept of component representation has been derived from the fact that a "real" building (made from individual components such as nuts, bolts and bar joists) can be "viewed" differently according to the frame of reference of the viewer. Each individual has the ability to infer and abstract from the assemblies of components a variety of different "models" ranging from a visceral, experiential understanding to a very technical, physical understanding. The component concept has already proven to be a valuable tool for reasoning about assemblies, interferences between components, tracing of load path and numerous other component related applications. In order to validate the component-based modeling concept this effort will focus on the development of spatial understanding from the component-based model. The discussions will, therefore, center about the representation of individual components and the development of spatial models and spatial reasoning from the component model. In order to frame the argument that spatial modeling and reasoning can be derived from the component representation, a review of the component-based modeling concept will precede the discussions of spatial issues.

summary This paper explores pedagogical and practical ramifications of implementing the component-based design paradigm through the actual construction process of a simple wood frame house for Habitat for Humanity. The house was digitally-modeled as part of an elective construction class, then physically constructed by students and faculty of the College of DAAP at the University of Cincinnati as part of a community service exercise. The digital model and a detailed database of individual components were mined in order to explore and exploit the complete and accurate electronic modeling of building, prior to actual construction.

title An Integrative Approach to Computer-Aided Design Education in Architecture
source February, 1985. [17] p. : [8] p. of ill
summary With the advent of CAD, schools of architecture are now obliged to prepare their graduates for using the emerging new design tools and methods in architectural practices of the future. In addition to this educational obligation, schools of architecture (possibly in partnership with practicing firms) are also the most appropriate agents for pursuing research in CAD that will lead to the development of better CAD software for use by the profession as a whole. To meet these two rather different obligations, two kinds of CAD education curricula are required: one which prepares tool- users, and another that prepares tool-builders. The first educates students about the use of CAD tools for the design of buildings, whereas the second educates them about the design of CAD tools themselves. The School of Architecture and Planning in SUNY at Buffalo has recognized these two obligations, and in Fall 1982 began to meet them by planning and implementing an integrated CAD environment. This environment now consists of 3 components: a tool-building sequence of courses, an advanced research program, and a general tool-users architectural curriculum. Students in the tool-building course sequence learn the principles of CAD and may, upon graduation, become researchers and the managers of CAD systems in practicing offices. While in school they form a pool of research assistants who may be employed in the research component of the CAD environment, thereby facilitating the design and development of advanced CAD tools. The research component, through its various projects, develops and provides state of the art tools to be used by practitioners as well as by students in the school, in such courses as architectural studio, environmental controls, performance programming, and basic design courses. Students in these courses who use the tools developed by the research group constitute the tool-users component of the CAD environment. While they are being educated in the methods they will be using throughout their professional careers, they also act as a 'real-world' laboratory for testing the software and thereby provide feedback to the research component. The School of Architecture and Planning in SUNY at Buffalo has been the first school to incorporate such a comprehensive CAD environment in its curriculum, thereby successfully fulfilling its obligation to train students in the innovative methods of design that will be used in architectural practices of the future, and at the same time making a significant contribution to the profession of architecture as a whole. This paper describes the methodology and illustrates the history of the CAD environment's implementation in the School

title An Expert System Approach to Computer-Aided Participatory Architectural Design
source February, 1985. 16 p. : ill. includes bibliography
summary Increased satisfaction of the built environment can be achieved by more effective communication between the people who use that environment and the designers who form it. Participatory design is a method which educates and involves the users in the actual design process so that such a communication becomes possible. Methods that have so far been developed for participatory design have proven to be too limited, due mainly to the large time demands they place on architects. An effective participatory design method can be achieved by the use of a knowledge-based expert system which is capable of providing an educational design experience to the user. The development and implementation of such a system, specifically for the design of single family homes, is the focus of this paper

summary Ceramic building material is a useful passive modulator of the environment. The subject area is based on traditional cultural and material knowledge of clay properties: from amphora to rammed earth building; and ranges to present uses: from desiccants and space shuttle tile patterns to bio-ceramics. The primary consideration is to control material density and porosity in a tile component, in response to specific environmental conditions. This depends on a number of key physical principles: the ability of the material to absorb thermal energy, the ability to absorb and then ‘wick’ moisture within the pore structure, and the decrement factor or ‘time lag’ of the effect. The interplay between these properties point to the importance of directionality in the porous microstructure, at the boundary layer. Material characteristics have been investigated in the laboratory at a micron scale and in the ceramics workshop at full scale, with some interplay between the two. Recent work done on monitoring has led to the development of software tools that allow feedback (approaching real time)- a visual representation of the dynamic thermal and hygrometric properties involved.

summary This paper discusses the development of an informed Design-to-Robotic-Production (D2RP) system for additive manufacturing to achieve performative porosity in architecture at various scales. An extended series of experiments on materiality, fabrication and robotics were designed and carried out resulting in the production of a one-to-one scale prototype. In this context, design materiality has been approached from both digital and physical perspectives. At digital materiality level, a customized computational design framework is implemented for form finding of compression only structures combined with a material distribution optimization method. Moreover, the chained connection between parametric design model and robotic production setup has led to a systematic study of certain aspects of physicality that cannot be fully simulated in the digital medium, which then establish a feedback loop for underrating material behaviors and properties. As a result, the D2RP system proposes an alternative method of robotic material deposition to create an informed material architecture.

summary The paper concerns the potential of sensors as architectural design tools in different spatial and temporal scales. In particular, the focus is on how sensors are able to operate in a constantly changing environment, and how sensors might nurture an intuition of otherwise non perceivable aspects of performance within architecture.The study discus two set-ups. Firstly; an onsite sensor reading of changing performance between a refurbished and a classic Arabic house; the study is in large spatial and temporal scale. Secondly; a model design setup where the performance of the same Arabic house typology is tested in small spatial and small temporal scale. The study shows how large scale architecture can be investigated through the use of sensor chaining and how simple sensors can be implemented in a design task in order to give insight to certain aspects of performance. The paper concludes with a discussion on a more general sensor strategy for changing environments and design setups.

summary Acoustic performance is defined by the parameter of reverberation time; however, this does not capture the acoustic experience in some types of open plan spaces. As many working and learning activities now take place in open plan spaces, it is important to be able to understand and design for the acoustic conditions of these spaces. This paper describes an experimental research project that studied the design processes necessary to design for sound. A responsive acoustic surface was designed, fabricated and tested. This acoustic surface was designed to create specific sonic effects. The design was simulated using custom integrated acoustic software and also using Odeon acoustic analysis software. The research demonstrates a method for designing space- and sound-defining surfaces, defines the concept of acoustic subspace, and suggests some new parameters for defining acoustic subspaces.
