title Overcoming Repetition: Robotic fabrication processes at a large scale
source International Journal of Architectural Computing vol. 11 - no. 3, 285-300
summary In the context of the Future Cities Laboratory (FCL) of ETH Zurich, the Professorship for Architecture and Digital Fabrication of Fabio Gramazio and Matthias Kohler has set up a robotic laboratory to investigate the potentials of non-standard robotic fabrication for high rise constructions in Singapore. The high degree of industrialisation of this dominant building typology implies standardisation, simplification and repetition and accounts for the increasing monotony evident in many Asian metropolises. The aim of this research on material systems for robotic construction is to develop a new and competitive construction method that makes full use of the malleable potential of concrete as a building material. A novel, spatial, robotic "weaving" method of a tensile active material that simultaneously acts as the form defining mould, folds two separate aspects of concrete-reinforcement and formwork-into one single robotic fabrication process (see Figure 1). This in-situ process could permit the fabrication of structurally differentiated, spatially articulated and material efficient buildings.

summary What if we had materials that weren’t solid and static like traditional building materials are? What if these materials could dynamically change and adapt to varying environmental situations and stimulations and evolve and learn over time? What if they were autonomous, self-sufficient and independent but could communicate with each other and exchange information? What would this “living matter” mean for architecture and the way we perceive the built environment? This paper looks briefly at current concepts and investigations in regards to programmable matter that occupy various areas of architectural research. It then goes into detail in describing the most recent smart material installation “Resinance” that was supervised by Manuel Kretzer and Benjamin Dillenburger and realized by the 2012/13 Master of Advanced Studies class as part of the materiability research at the Chair for CAAD, ETH Zürich in March 2013. The highly speculative sculpture links approaches in generative design, digital fabrication, physical/ubiquitous computing, distributed networks, swarm behavior and agent-based communication with bioinspiration and organic simulation in a responsive entity that reacts to user input and adapts its behavior over time.

summary Interactive architecture is a fairly recent phenomenon enabled through new materials and technologies. Through experimentation architects are coping with questions of changeability, adaptability, and interaction. However, there are no comprehensive design methods to support this type of architecture. In this paper we aim to bring together methods that can support the design of interactive architecture. The methods are ordered in a methodological framework that provides an overview of possible approaches.

summary Due to improving technology and global competition today sky is the only limit for high towers of metropolitan areas. The increase in number of high rise has been ruining the silhouette of cities all over the world like Istanbul, whose identity and image have also been destroyed by skyscrapers dominating the seven slopes on which it was once built. The urbanization in Istanbul has somehow become homogenous and destructive over the topography. Despite of raising debates on the critical issue now and then, no analytical approach has ever been introduced. The research therefore, aims to analyze the change of Bosphorus silhouette caused by the emergence of high rise blocks in Zincirlikuyu-Maslak route since it was defined as a Central Business District and a high rise development area by Bosphorus Conservation Law in 1991. ArcGIS Desktop software and its analyst extensions are used for mapping, analyzing and evaluating the urban development within years. The application is considered to be the initial step for a decision support system which will assist in assigning ground for high rise buildings in Istanbul.

source FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.187-195
summary This paper describes a new methodology of deriving innovative hybrid designs using shape grammars of heterogeneous designs. The method is detailed within three phases of shape grammars: analysis, synthesis and evaluation. In the analysis phase, the research suggests that original rules of each design component are grouped in subclass rule sets to facilitate rule choices. Additionally, adding new hybrid rules to original rules expands the options available to the grammar user. In the synthesis phase, the research adopts state labels and markers to drive the design generation. The former is implemented with a user guide grammar to ensure hybridity in the generated design, while the latter aims to ensure feasible designs. Lastly evaluation criteria are added to measure the degree of innovation of the hybrid designs. This paper describes the derivation of hybrid minaret designs from a corpus of heterogeneous traditional minaret designs.

summary The paper presents an innovative semantic and parametric method to build 3D models to be used in cognitive-information systems. We integrated structured geometrical and documentary information resulting from multiple sources with the aim to enhance the knowledge of those sites within the frame of their historical evolution and their institutional management in a 3D GIS/DB. The developed applications were designed for different types of users, with a largely scalable interface, able to support different output devices and to work at different levels of iconicity. The system allows a full comprehension of the buildings in their own context, permitting to discover unknown relationships, to evaluate their architectural occupancy and to quickly access a complex system of information.

summary This paper aims to draw the necessary distinctions in order to contribute to identify, among all the objects that populate our world of perception, the urbanist´s own object of study. In systemic jargon, it aims to distinguish that elemental unity that ensures that a phenomenon is an urban one and none other. This, in order to help to distinguish in turn the urbanist´s own field of action. It calls into question the widespread belief that this object of study might be the already built city as current academic and professional tradition dictates and postulates instead the study of the urban protophenomenonalternatively, of the archetypal citizen- as a genuinely urban route for the attainment of urban knowledge.

source FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.717-726
summary We present a simulation platform to evaluate procedurally generated 3d city models with a set of agents representing urban street actors and pedestrians towards greenhouse gas emissions from transportation. Our aim is to give architects and urban planners an empiric tool to analyze, predict and quantify traffic fluctuations over time, and define the number of occupants, individual traffic and public transport in a city. In this project we show that the allocation of functions within a city is an important factor for the appearanceof traffic. The occupant’s decisions where they want to go are defined by the allocation of functions – and the distance defines the mode of transportation. We simulate the decision processes and gain information about the path, the mode of transportation, and the emissions they produce, and individual experiences like stress and effort. The autonomous driving cars are equipped with an acceleration based emission model allowing us to evaluate the inpact of jammed streets on the emission of cars.

source FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.379-387
summary The Attractive City Generator is an interactive installation with which users can create or rearrange virtual cities by placing and moving physical objects. Through the set of simple inputs that the users provide and which represent city areas, landscapes or landmarks, the ACG is capable of creating complex and growing cities. In addition, a plethora of factual feedback on these cities is calculated. Becoming physically involved enhances the learningprocess and increases the user’s interest. The users are drawn to the colourful and simple interface. Due to the practical feedback that the city returns, the users can feel more attached to the city they have created. A dynamic dialogue is formed between the city and its creators, that involves the wishes of the users versus the needs of the virtual city, the practical interaction on the table versus the theoretical calculations taking place inside the computer, the physical input versus the digital output.

summary We investigate the recent coincidence of rapid global urbanization and unprecedented formal freedom in architectural design and ask whether this coincidence is an uneasy one. To study an extreme case of the new exotic geometries made possible through CAAD, we employ algebraic surfaces to experimentally design architecture in an university-based research and experimental design project. Such surfaces exhibit unprecedented complexity and new geometric and topological features yet are highly sound and harmonious. We continue and extend our research presented at the eCAADe 2009 conference in Istanbul.

source FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.265-274
summary This paper shows the first results of a prototype implementation of a generative urban design tool. This implementation will form part of a design support tool for a GIS based platform defined to formulate, generate and evaluate urban designs. These three goals, formulation, generation and evaluation are integrated by connecting three modules developed individually for each goal. In this paper we focus on the implementation of the generation module showing a prototype developed on the Integrated Development Environment (IDE) of AutoCAD Civil 3D. This implementation attempts to encode the design moves of the urban planner into design patterns supported on grammar formalisms which allow for design synthesis and design exploration in the field of urban design.

summary This paper presents an ongoing research on computer supported collaborative design carried out by the ARIAM-LAREA laboratory at the Superior National School of Architecture of Paris-LaVillette. The aim of this research is to analyze computer mediated architectural design practices in order to identify the specific “operations of conception”. Two observations of architectural collaborative design supported by computer tool called “Studio Digital Collaboratif” have been conducted: one concerning collaboration between architects, in laboratory, the other one between architects and engineers in a real situation of design. Our analysis use two concepts to explain the collaborative conception in architecture: classes of operation of conception and operation of conception. They permit to identify the elementary operations of conception and pragmatic operations of collaboration. According to the first results it seems that classes of operation of conception are shared but operations of conception seem to be unshared.

source FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.151-156
summary The paper follows the development of digital tools for architects and briefly discusses their utility within education and practice. The move from static CAD tools to time based media followed by programmatic processes and virtual environment design is addressing the evolution of the profession and to an extent reflects practitioners’ needs. The paper focuses on the notion of interactivity and how it is been addressed in various fields. Borrowing from computer science and game design the author presents a course dealing with designing interactivity, responsiveness and users feeding their input back in the design. The aim of the paper is to analyse and support a new set of tools in architectural curricula that will implement interactivity and integrate it into spatial design leading to a holistic approach promoting intelligence, hybridity and responsiveness of the built environment. Following, the elaboration of the rationale, a brief discussion on tools and project directions is carried out.

title Spatial Visualization of abstract Information: A Classification Model for Visual Spatial Design Guidelines in the Digital Domain
source Swiss Federal Institute of Technology, ETH Zurich
summary Visualization of abstract information refers to the design of graphical representations of information that has no simple relation to known concrete or physical forms. Designing visualizations of abstract information requires proposing visual representation for often a large body of data pants. determining a meaningful structure for the complex relations among them and suggesting a method for Interacting with this body of data. Spatial perception plays an Important role for cognitive processing when interacting with abstract information, slice spatially-organized Information can be accessed and operated on rapidly and effortlessly, especially when a spatial arrangement reveals the conceptual organization of Information.

This thesis focuses on aspects of the spatial visual design of abstract information presented as computer-generated. dynamic and interactive images accessible through flat displays. The process of spatial visualization design is shaped by various factors including interactive, perceptual, navigational as well as organizational and metaphorical aspects and as such requires an interdisciplinary approach. Therefore, in researching spatial visual design. it is crucial to use methods facilitating the process of sharing competencies among different disciplines.

In this thesis, we introduce a new classification model accommodating features important in designing effective spatial visualizations of abstract information. To enhance the effectiveness of spatial visualization, this model offers a holistic approach in classifiying spatial Visualization features. As part of the model, we analyze properties already used in architectural representation and other visual design disciplines for spatial presentations as well as investigate their potential usage in digital domains of abstract information. The process of spatial visualization In the digital environment is mostly based on the practical experience of a designer. and therefore the majority of spatial design know-how is heuristic in nature. Based on this assumption, we present a set of guidelines addressing the general problem of spatial design.

The Spalial Design Classificahon Model, Visual Spatial Properties and Spatial Design Guidelines build an extendable infrastructure which becomes a first step towards augmenting the quality of spatial information design- We propose to use this infrastructure as a general blueprint for structuring the exchange of expertise in Interdisciplinary problem-solving processes.

The use of this construct or method made the design process more intelligible for the students who took part in the project and helped managing the team work. We expect that these rules will also allow the automation of the production of design alternatives and construction drawings for new buildings in the campus.

title Analogical and inductive reasoning in architectural design computation
source Swiss Federal Institute of Technology, ETH Zurich
summary Computer-aided architectural design technology is now a crucial tool of modern architecture, from the viewpoint of higher productivity and better products. As technologies advance, the amount of information and knowledge that designers can apply to a project is constantly increasing. This requires development of more advanced knowledge acquisition technology to achieve higher functionality, flexibility, and efficient performance of the knowledge-based design systems in architecture. Human designers do not solve design problems from scratch, they utilize previous problem solving episodes for similar design problems as a basis for developmental decision making. This observation leads to the starting point of this research: First, we can utilize past experience to solve a new problem by detecting the similarities between the past problem and the new problem. Second, we can identify constraints and general rules implied by those similarities and the similar parts of similar situations. That is, by applying analogical and inductive reasoning we can advance the problem solving process. The main objective of this research is to establish the theory that (1) design process can be viewed as a learning process, (2) design innovation involves analogical and inductive reasoning, and (3) learning from a designer's previous design cases is necessary for the development of the next generation in a knowledge-based design system. This thesis draws upon results from several disciplines, including knowledge representation and machine learning in artificial intelligence, and knowledge acquisition in knowledge engineering, to investigate a potential design environment for future developments in computer-aided architectural design. This thesis contains three parts which correspond to the different steps of this research. Part I, discusses three different ways - problem solving, learning and creativity - of generating new thoughts based on old ones. In Part II, the problem statement of the thesis is made and a conceptual model of analogical and inductive reasoning in design is proposed. In Part III, three different methods of building design systems for solving an architectural design problem are compared rule-based, example-based, and case-based. Finally, conclusions are made based on the current implementation of the work, and possible future extensions of this research are described. It reveals new approaches for knowledge acquisition, machine learning, and knowledge-based design systems in architecture.

source FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.237-242
summary This paper is a presentation of the preliminary framework for the design and fabrication of the soft-skin. Today, the digital technology applied in the architecture field is everywhere. However, there are still lots of fantastic free form architecture uncompleted and remained on the paper architecture or only the digital visual simulated model. Until now, most of the finished free form cases are consisted of the skin and bones, or only the bones. The complete soft-skin cases without the bones are fewer and the process remains untold. Based on the parametric environments and biology, how might you design a free form without the bones? How could you make the soft skin stand up? The research starts a series of exploration of the design and fabrication for the soft skin, and seeks to propose the preliminary framework as a helpful reference for the designers who deal with the soft skin project.

summary A new housing complex on the Campus of the University of Patras, Greece, is expected to serve as a test-bed for experimentation with a parametric design process that integrates significant climatic data. To optimize the environmental performance of the proposed housing complex a parametric design algorithm has been developed. The algorithm links the weather data in the area with the site topography and the basic geometric features of the buildings on the site. To explore the interaction of the building features with the prevailing winds in the area and the solar exposure throughout the year various software applications, including computational fluid dynamics (CFD) simulations, have been utilized. The inclusion of wind data in the algorithm renders it particularly effective. The developed parametric process has been useful during the early design phase when studies on various patterns for arranging the buildings on the site were conducted. The parametric process has facilitated the configuration of the typical building block as well.

title A Computer-Assisted Diagramming System
source Swiss Federal Institute of Technology, ETH Zurich
summary This research investigates characteristics and generation of graphic diagrams used in support of analysis, presentation and synthesis of information in various domains. The research is aimed at the development of a software system which can be used to specify, generate and manipulate diagrams similar to the way they are represented and operated upon in traditional media.Diagrams are graphic representations of symbolic propositions that allow tentative reasoning and inferencing, and enable a person to focus on selected aspects of a situation that are deemed of interest. The economy and directness of expression found in diagrams seem to be the prime reasons why they are so ubiquitous in many domains. Despite these advantages, studies into supporting diagrammatic representations using computers are rather sparse. This research is an attempt at developing a comprehensive framework of thought in this direction.In the context of design disciplines like architecture, this research forms a part of the continuum of studies in computer aided design techniques and tools. While a large number of tools and techniques in CAD have emerged so far, usage of such tools, due to their underlying representations, expects and demands commitment of too many details too early in the design process. This research is aimed at characterizing and developing a computer based diagramming system to support tentative reasoning using diagrams, and thus hopes to extend the scope of CAD environments in design. The thesis first articulates motivations for this topic in detail. Next, a discussion on the role played by diagrams as conceptual tools in various domains is presented. It is followed by a detailed look at characteristics and components of diagrams viewed as a graphic communication system. Next, a comprehensive set of requirements for an ideal software environment for diagramming tasks is developed. A prototype system called CDT was implemented and is used to demonstrate ideas developed in this research. The study concludes with some observations on contributions of this research effort and possible future extensions.
