title Cognition Model in Conceptual Designing

summary Both design researchers and cognitive scientists have developed various process models to study human creative behaviour in design. The models developed are often based on observations of design processes and analysis of design protocols. This research paper reports the-stateof- the-art in the area of cognition models that present design activities in conceptual designing. The research paper investigates the approaches of these cognition models. A new approach of a cognition activity model in conceptual designing is proposed. The new approach used in the introduced model takes into the account factors and activities that are related to the external environment of design (design medium). The external environment has an important role in the cognition activities and the evaluation process in a way that can hardly be ignored or neglected. The presented model of cognition activities in conceptual designing highlights two main factors employed in all the iteration loops of the model, namely: media use and representation. Case studies of architecture students’ designs have been analyzed. The analysis of these case studies helped in forming the proposed model. Various results have been concluded and reported.

title Representing Reflective Practice in a Remote Design Collaboration Process
source Digital proceedings of the 3rd Conference of International Association of Societies of Design Research (IASDR 2009), COEX, Seoul, Korea, pp. 1317 – 1326.
summary This paper addresses a new method to describe the remote collaborative design process from the perspective of reflective practice. We aim at understanding the mutual effect between internal and external structures in remote collaborative design. According to the cognitive coding scheme of Suwa et al., we encoded the process into a set of indices—new, continual and revisited—that describe each primitive design move. In a case study which involved the authors as design collaborators, we identified the degree of dependency among these moves and developed a 3D graphical representation to account for reflective practice between us as collaborators. In this representation, we re-interpreted our collaborative process through three main axes: axis of idea exchange as lateral component, axis of idea development as vertical component, and axis of dependency as depth component. We believe this representation can be used to re-interpret the collaboration process among geographically dispersed design team members.

title The Use of the Smart Geometry through Various Design Processes: Using the programming platform (parametric features) and generative components
source Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 297-304
summary The emergence of parametric generative design tools and prototyping manufacturing technology led to radical changes in architectural morphologies. This change increased the opportunity to develop innovative smart geometries. Integrating these algorithms in the parametric softwares led to variations in building design concepts increasing alternatives and decreasing the repetitive work previously needed in conventional CAD software. The chosen software in this research is Generative Components (GC). It is a software design tool for an associative and parametric design platform. It is tested for using Global Variables with associative functions during the concept creation and form GC comprises features. The results presented in this research may be considered an introduction to the smart geometry revolution. It deals with the generative design which applied in the design process from conceptual design phase, defining the problem, exploring design solutions, then how to develop the design phases. Office building is a building type which encourages new forms that needs computational processes to deal with repetitive functions and modular spaces and enclosed in a flexible creative structural skin. Generative design helps the office buildings to be arranged, analysed, and optimized using parameters in early stages in design process. By the end of the research, the use of the smart geometry in a high rise office building is defined and explained. The research is divided into three parts, first a summary of the basic theories of office buildings design and the sustainable requirements that affect it, and should be integrated. Secondly, the previous experiences in generating office buildings by Norman foster and Sergio Araya. At last, a case study is proposed to test and evaluate the use of the parametric generative methodology in designing an office building with specific emphasis on the function, environmental aspects and form generation using Generative Components (GC) Software.

summary The Catoptric Surface research project explores methods of reflecting daylight through a building envelope to form an image-based pattern of light on the interior environment. This research investigates the generation of atmospheric effects from daylighting projected onto architectural surfaces within a built environment in an attempt to amplify or reduce spatial perception. The mapping of variable organizations of light onto existing or new surfaces creates a condition where the perception of space does not rely on form alone. This condition creates a visual effect of a formless atmosphere and affects the way people use the space. Often the desired quantity and quality of daylight varies due to factors such as physiological differences due to age or the types of tasks people perform (Lechner 2009). Yet the dominant mode of thought toward the use of daylighting tends to promote a homogeneous environment, in that the resulting lighting level is the same throughout a space. This research project questions the desire for uniform lighting levels in favor of variegated and heterogeneous conditions. The main objective of this research is the production of a unique facade system that is capable of dynamically redirecting daylight to key locations deep within a building. Mirrors in a vertical array are individually adjusted via stepper motors in order to reflect more or less intense daylight into the interior space according to sun position and an image-based map. The image-based approach provides a way to specifically target lighting conditions, atmospheric effects, and the perception of space.

title Architectural Abstraction and Representation: The embodied familiarity of digital space
source Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 305-321
summary This paper argues that familiarity is the tool that enables the understanding of space abstraction and representation. Familiarity in this context is independent from embodied interaction, and is crudely based on the connection between the various similar images of space; in this particular case, virtual space. Our investigation into the nature of human interaction with space, its abstraction and its representation is based on the critical contrast between the outcomes of interaction with two virtual versions of a physical reality; the first version is a non-linear interactive graphical abstraction of the space where no assertions or indicators are given as to whether or not there is a relationship between the abstraction and its physical reality, whereas the second is a none-linear interactive 3D virtual environment clearly representing the physical space in question. The paper utilises qualitative methods of investigation in order to gain an insight into human embodied experience in space, its abstraction and representation.

doi https://doi.org/10.52842/conf.caadria.2009.005
summary This project examines a non-traditional method of construction generated through a digital design process that leverages digital fabrication techniques related to masonry construction. Where as architects’ use of computers first affected shape and structure, it is now additionally affecting material, construction, and craft. This design proposal explores these concepts through the production of a wall using simple configuration and reconfiguration of a repeated module adaptable to differing and unique contexts and site conditions. The masonry module is designed and built through the exploration of a CAD-CAM process. The prototypes produced investigate the repetition of a single module unit, manipulated and interlocked resulting in a continuous surface that is more than just the sum of its individual parts. The material, construction and craft of each unit informs and challenges the entire project to question the making of the masonry module into a wall.

summary In the paper the main stages of the evolution of aided design methods (which led to the formation of new spaces of creation) will be presented. The first way in which human tried make his work easier were direct introduction of scientific researches in practice. Comprehension and studying the structure of design process creates real conditions for increase of its efficiency. Thanks to methodological researches the systematic design methods were developed. The next steep was introducing the IT technologies into the design process. Firstly as a simple tool, and after as the participant of the creative process. Last years an idea of “direct designing” – the use of VR as an environment for the spatial forms creation was elaborated. The environment starts to play a role of an active mediator joining the real world, the men and the computer. In this environment the designer has access to the processes and sources of creative activity. The qualitatively new process of architectural designing arises.

summary We describe the exploration of the manifold novel shapes found in algebraic geometry and their application in architectural design. These surfaces represent the zero-sets of certain polynomials of varying degrees. They are therefore very structured, coherent and harmonious yet at the same time geometrically and topologically highly complex. Their application in design is mostly unprecedended as they have only recently begun to become accessible through novel software tools. We present and discuss experimental student design and research projects where shapes found in algebraic geometry were developed into pavilion designs. We describe historic precedents for the inspiration of art and architecture through mathematics and show how algebraic surfaces can be used to expand architects’ sculptural vocabulary, make the utmost of three-dimensional sculptural qualities, employ shapes that have a strong internal structure, transcend the imaginable and explore polynomials as a new kind of shape-making tool.

summary This paper presents a shape grammar for planned urban spaces intending an implementation for generative urban design. This implementation will form part of an urban design support tool defined to formulate, generate and evaluate urban designs. The goal is to formulate urban program descriptions according to context conditions using a description grammar and generate alternative design solutions using a shape grammar. The generation is guided by several evaluation processes performed by an evaluation module. In this paper we are focusing on the definition of the generic shape grammar using an existent urban plan as a case study. The aim is to encode the design moves of the urban designer into generic grammar rules amenable for specific instantiations through the customization of rule parameters.

title Parametricism for Urban Aesthetics - A flawless order behind chaos or an over-design of complexity
source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 105-112
summary Over the last decade, paradigm shifts in the philosophy of space-time relations, the change from space-time to spatio-temporality, caused significant changes in the design field, and introduced new variations and discourses for parametric approaches in architecture. Among all the discourses, parametricism is likely the most spectacular one. The founder of parametricism, Patrik Schumacher (2009) describes it as “a new style,” which has “the superior capacity to articulate programmatic complexity;” and “aesthetically, it is the elegance of ordered complexity in the sense of seamless fluidity.” In its theoretical background, Schumacher (2011) affiliates this style with the philosophy of autopoiesis, the philosophy that stands between making and becoming. Additionally, parametricism concerns not only the physical geometry in making of form; but also discusses the relational and causal aspects in becoming of form. In other words, it brings the aesthetic qualities in making through the topological intelligence behind becoming. Regarding that, parametricism seems an effective way of managing /creating complex topologies in form-related issues. However, when it comes to practice, there are some challenging points of parametricism in large-scale design studies. Thus, this work underlines that the dominance of elegance for urban planning has the potential of limiting the flexible and dynamic topology of the urban context, and objectifying the whole complex urban form as an over-designed product. For an aesthetic inquiry into urban parametricism, this paper highlights the challenging issues behind the aesthetic premises of parametricism at the urban design scale. For that, Kartal Master Plan Design Proposal by Zaha Hadid Architects (2006) will be discussed as an exemplary work.

summary ArtBus is a protocol and hardware bus for interfacing computers to sensors and actuators. It is a distributed interface, meaning that different parts of an ArtBus system can be at different locations in a space. ArtBus devices can be made on any embedded platform or microcontroller. While unconventional in some ways, ArtBus makes use of engineering design inspired by long established supervisory control and laboratory instrumentation practice. At the same time it is a simple, flexible interface which should be viable into the next generation of media devices and embedded control.

title Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called “gingerbread houses”, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

summary The goal of this research is to define a methodology for the construction of complex non-repeating surfaces and structures that rely on the formulation of a singular tectonic mechanism. Computational systems like cellular automata seem to suggest that it might be possible for modular material systems to self-assemble into complex organizations. A single series of modular parts could be capable of producing not only complex behavior, but also, depending on initial conditions, simple periodic behavior. The research outlined in this paper uses simple geometric transformations to produce tectonic computers that can be applied to a variety of building systems. This paper outlines a methodology for encoding and decoding material assemblages as discrete computational systems. Exploiting the combinatorial nature of tectonic systems makes it possible to produce a population of “material algorithms” capable of exhibiting a wide range of behaviors. Encoding assemblages as discrete systems affords the designer the ability to enumerate and search all possible permutations of a tectonic system. In this paper, we will discuss the calculations and computational processes used to encode material assemblages as populations of discrete algorithms.

summary Schools and teachers increasingly apply Online Learning Environments for teaching and course management. In many cases, an existing platform is used to support the curriculum. At the K.U. Leuven in Belgium a campus-wide platform is provided, using a commercial Content Management System. At the same time, the Design and Building Methodology research group at the Department of Architecture, Urbanism and Planning developed a custom portal to organize Computer Aided Architectural Design courses and seminars. Integration of this portal into the university system was rather disappointing, since much of the flexibility and customizability was lost, without any chance of filling in the gaps. This article discusses the possibilities and limitations of existing web-based systems to support Computer Aided Architectural Design teaching and reports on our own experiences from the last decade. A comparison of selected systems is juxtaposed with the requirements derived from these experiences.

summary This paper discusses a collaborative project by RDAI architects, Bollinger+Grohmann and the timber construction company Holzbau Amann. The project is located in a former swimming pool in Paris and it is part of the new interior of a flagship store of the French fashion label Hermes. In late 2009, Rena Duma Architects, asked Bollinger+Grohmann to collaborate as structural engineers on a challenging design proposal within a very short timeframe. Three wooden lattice structures, the so-called “bulle” and one monumental staircase with a similar design approach characterize the interior of the new flagship store. The lattice structures are dividing the basement into different retail spaces. They vary in height (8-9 m) and diameter (8-12 m) and have a free-form shaped wicker basket appearance. Wood was the chosen material for these structures to strengthen the idea of the wickerbaskets and to create an interior space with a sustainable and innovative material.

summary Since 3D city models need to be realistic not only from a bird's point of view, but also from a pedestrian's point of view, the interest in the generation of 3D façade models is increasing. This paper presents two successive algorithms for automatically segmenting building façades scanned by Terrestrial Laser Scanner (TLS) into planar clusters and extracting their contours. Since majority of façade components are planes, the topic of automatic extraction of planar features has been studied. The RANSAC algorithm has been chosen among numerous methods. It is a robust estimator frequently used to compute model parameters from a dataset containing outliers, as it occurs in TLS data. Nevertheless, the RANSAC algorithm has been improved in order to extract the most significant planar clusters describing the main features composing the building façades. Subsequently, a second algorithm has been developed for extracting the contours of these features. The innovative idea presented in this paper is the efficient way to detect the points composing the contours. In order to evaluate the performances of both algorithms, they have successively been applied on samples with different characteristics, i.e. densities, types of façades and size of architectural details. Finally, a quality evaluation based on the comparison of planar clusters and contours obtained manually has been carried out. The results prove that the proposed algorithms deliver qualitative as well as quantitative satisfactory results and confirm that both algorithms are reliable for the forthcoming 3D modelling of building façades.
