title	Towards Changeability
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 189-200
summary	Many buildings around the world have undergone successive changes over their life cycles. Regardless of the type or size of a building there are usually requirements for change due to several unanticipated forces and emerging uncertainties that act upon them. These changes might be in the building’s spatial, structural or service systems. This can be due to changes in the needs of occupants, the market demand or technological advances. Although buildings undergo change, current design practice does not address this and buildings are still designed as if they will remain static. This paper proposes an Adaptable Buildings Design (ABD) Framework to address the issue of adaptability in building design. Using this methodology uncertainties and future changes are first identified. To increase the building’s longevity, flexibility options are embedded and design rules are formulated to trigger these options when necessary. The value of adaptability is then assessed by implementing several simulations using Real Options Analysis (ROA). To demonstrate the approach, the ABD is applied to a multi-use commercial building case study. Flexibility is embedded in the building’s design across several systems allowing it to change and evolve over time based on a set of design rules. The buildings adaptability is then assessed using ROA. Positive results demonstrate the strength of the proposed methodology in addressing future change and uncertaintie.

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 ‚Äúgingerbread houses‚Äù, 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	Digital technologies and processes have been used to generate architectural form for over two decades. Recent advances in digital technologies have allowed virtual digital environments to be constructed from physical movement. But can a bridge that connects the physical and virtual realms be developed? Can this, currently arbitrary form making be grounded in human activity and subsequently be integrated in to real time, space, and place. This research asks how space generated from the process of digital morphogenesis can be related to meaning beyond just the creation of form. Existing research asks how new form can be discovered, or what material and structural possibilities can be derived from form, through these morphological processes. The aim of this research project is to complete the loop, physical–virtual–physical, and to connect these digital processes to meaning through human activity. Its aim is to discover the consequences of generated spatial envelopes that are manipulated through digital morphogenesis and related to specific human activity, in the pursuit of possibilities for a digitally generated architecture that is socially engaged. This is not random form finding, wherein architecture tries to imitate biological processes or form, but form finding that is connected to a primary architectural concern, how is the architecture being used by humans.

title	Patterns, heuristics for architectural design support: making use of evolutionary modelling in design
doi	https://doi.org/10.52842/conf.caadria.2010.283
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 283-292
summary	Software used by architectural and industrial designers has shifted from becoming a tool for drafting, towards use in verification, simulation, project management and remote project sharing. In more advanced models, design parameters for the designed object can be adjusted so that a family of variations can be produced rapidly. With the advances in computer aided design (CAD) technology, design options can now be generated and analyzed in real time. However the use of digital tools to support design as an activity is still at an early stage and has largely been limited in functionality with regard to the design process. To date, major CAD vendors have not developed an integrated tool that is able to leverage specialised design knowledge from various discipline domains (known as expert knowledge systems) as well as to support the creation of design alternatives that satisfy different forms of constraints. We propose that evolutionary computing and machine learning be linked with parametric design techniques in order to monitor a designer’s cognition and intent based on their design history. This will lead to results that impact future work on design support systems which are capable of supporting implicit constraint and problem definition for wicked problems that are difficult to quantify.

summary	As technology advances, users become more detached from the way things work and are produced. Users end up being pure consumers and leave their positions as decision makers behind. Before the architectural and building processes were industrialized, most practitioners of so - called vernacular architecture were in fact the inhabitants of what they built, which easily met their specific personal needs because they were in total control of the building process. This paper will focus on the possibility of non - architect users of architecture as decision - makers in order to establish designs that satisfy their individual needs.

summary	As technology advances, users get more detached from the way things work and are produced. Users end up being pure consumers and leave their positions as decision makers behind. Before the architecture and buildings processes were industrialized, most practitioners of the so-called vernacular architecture were in fact the dwellers of what they built and they easily met the specific personal needs since they were in total control. Some “architectural theorists have turned to vernacular construction with the conviction that such buildings and settlements express the interconnectedness between humans and the landscapes they live in.” (Beesley and Bonnemaison 2008). Considering the present day intense building activity, such relationship of dweller and architecture seems not possible excepting a very few examples to later referred to. This paper will instead focus on the possibility of the non-architect users of architectures as decision makers in order to reach designs that meet the requirements of their addressees.

title	The Chair Back Experiment: Hierarchical Temporal Memory and the Evolution of Artificial Intelligence in Architecture
source	International Journal of Architectural Computing vol. 8 - no. 2, 151-164
summary	Computational synthesis tools that automatically generate solutions to design problems are not widely used in architectural practice despite many years of research. This deficiency can be attributed, in part, to the difficulty of constructing robust building specific databases. New advances in artificial intelligence such as Hierarchical Temporal Memory (HTM) have the potential to make the construction of these databases more realistic in the near future. Based on an emerging theory of human neurological function, HTMs excel at ambiguous pattern recognition. This paper includes a first experiment using HTMs for learning and recognizing patterns in the form of visual style characteristics in three distinct chair back types. Results from the experiment indicate that HTMs develop a similar storage of quality to humans and are therefore a promising option for capturing multi-modal information in future design automation efforts.

doi	https://doi.org/10.52842/conf.acadia.2010.305
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 305-312
summary	The instrumental and aesthetic implications of architecture’s engagement with science and technology has a long history, part of which includes the period following the Second World War when the rapid technological advances of the Industrial Revolution merged with a general cultural mindset characterized by themes of progress and futurism. For postwar thinkers like Reyner Banham, this interest in a futurist architecture suggested an approach to design rooted less in architectural precedent than technological extrapolation. While a precedent based approach might be viewed as more disciplinary in nature, technological extrapolation suggests an inclination towards interdisciplinarity. Thus, Banham’s concept of extrapolation encouraged architects to look beyond the limits of their own discipline as a means of discovering new forms of knowledge and expertise. Indeed Banham was engaged in taking stock of the technological advances particular to his time while simultaneously anticipating the implication of these advancements for the future. To this extent, the postwar period and its inherent futurism provides a useful and poignant lens through which to take stock of our own technological climate. Given the equally revolutionary advances in computer technology in the last twenty years, our contemporary moment can be seen as having many parallels with the postwar period, and not unlike the postwar generation of architects and thinkers, contemporary designers are inevitably faced with the challenge of engaging new technological advances and their implications for architecture. In our current age of digital and biological technologies, these advances are both rapid and widespread, and include LED and fiber-optic lighting systems, motion sensing, interface design, solar tracking photovoltaic skins and wind harnessing technologies, magnetic levitation, and robotics. This paper begins with an examination of design work and criticism from the postwar period and proceeds to utilize that examination as an historical framework for addressing issues of contemporary design and 21st Century technological advancement.

title	Augmented Reality-Based Education and Fire Protection for Traditional Korean Buildings
source	International Journal of Architectural Computing vol. 8 - no. 1, 75-91
summary	This study examines an application of Augmented Reality technology (AR) for Korean Cultural Traditional Buildings, specifically, the Namdaemun Gate, "National Treasure No 1" of the Republic of Korea. Unfortunately, in February 2008, the Namdaemun Gate burned down, despite the efforts of many firemen, as the main difficulty was getting the fire under control without any structural knowledge of the wooden building. Hence, with the great advances in digital technology, an application of virtual technical information to traditional buildings is needed, and the new technology of AR offers many such advantages for digital architectural design and construction fields. While AR is already being considered as new design approach for architecture, outdoor AR is another practical application that can take advantage of new wearable computer equipment (Head-mounted display also know as HMD, position and orientation sensors, and mobile computing) to superimpose virtual graphics of traditional buildings (in this case, Namdaemun Gate) in a real outdoor scene. Plus, outdoor AR also allows the user to move freely around and inside a 3D virtual construction, thereby offering important training opportunities, for example, specific structural information in the case of firemen and mission planning in the case of a real-life emergency. In this example, the proposed outdoor AR system is expected to provide important educational information on traditional wooden building for architects, archaeologists, and engineers, while also assisting firemen to protect such special buildings.

title	Assessing innovation in hybrid designs using shape grammars
doi	https://doi.org/10.52842/conf.caadria.2011.545
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 545-554
summary	Al-kazzaz et al (2010) described hybrid adaption technique to generate innovative designs from heterogeneous precedents using shape grammars. An evaluation of the degree of innovation in the hybrid designs gave feedback to grammar users before and after applying a rule. Innovation was assessed using variables derived from the internal structure of the grammar such as: the number of antecedents in the corpus having the same rule; the number of rules in a subclass rule set having the same geometry; etc. However, the validity of the innovation assessment was unclear and the use of the feedback measures was not demonstrated. Accordingly, this study aims to verify the credibility of the innovation measures and to identify the independent variables that a user can control to achieve a significant impact on each innovation measure as a dependent variable.

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.

title	Automated 3D Reconstruction of Interiors from Point Clouds
source	International Journal of Architectural Computing vol. 8 - no. 1, 55-73
summary	We present a new technique for the fully automated 3D modelling of indoor environments from a point cloud. The point cloud is acquired with several scans and is afterwards processed in order to segment planar structures, which have a noticeable architectural meaning (floor, ceiling and walls) in the interior. The basic approach to data segmentation is plane sweeping based on a hypothesis-and-test strategy. From the segmentation results, the ground plan is created through cell decomposition by trimming the two-dimensional ground space using half-space primitives. An extension in height of the ground contours makes the generation of the 3D model possible. The so-reconstructed indoor model is saved in CAD format for analysis and further applications or, simply, as a record of the interior geometry.

title	Multi-touch - the future of design interaction
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. 557-572.
summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

title	Parametric Documenting of Built Heritage: 3D Virtual Reconstruction of Architectural Details
source	International Journal of Architectural Computing vol. 8 - no. 2, 135-150
summary	This paper examines 3D modelling of architectural elements with the help of parametric components. Such components may be useful within the framework of projects dealing with virtual 3D reconstruction of heritage monuments. Architectural components of the built heritage often have complex geometry. We studied the various geometrical shapes of a given architectural element, representative of a specific period and place. This study allowed us to identify the parameters and to implement parametric objects (in Maya Environment [1]). We also developed a Graphical User Interface (GUI) to answer the user's needs while generating the 3D model representing the architectural element. Within this GUI, the user is able to make adjustments with the help of laser point clouds from laserscanning, 2D plans or photographs. We exemplify our method with a case study dealing with openings and lintels. The corpus under study consists of elements of the built heritage of Montreal (Canada) and Nancy (France).

title	Abstractions for information based design
source	International Journal of Architectural Computing vol. 8 - no. 3, pp. 233-256
summary	This paper discusses how live linkages between parametric geometry, structural analysis and optimization can be leveraged to explore an architectural massing from different perspectives of optimum assuming a set of cost and value characteristics. Broad performance measures such as program area, cladding surface and structural quantities were computed for each geometry variation and collected. Optimums from different perspectives (structure, developer, designer) were extracted for each height category and compared. To further inform and engage stakeholders, a variety of visualization and filtering techniques have been implemented. These new techniques and associated distillation of data aids the design team in understanding the design space. A script based approach towards geometry and data management has led to a shift towards active option evaluation and a more interactive approach to form exploration. A generic workflow for structural analysis, design and optimization has been implemented and this ability to engineer at a greater velocity will move the design profession towards a more collaborative and information based design environment.

summary	Real time walkthrough is a valuable resource, especially in the early stages of the design process. Assessing how shadows and reflections behave enables architects to make better choices regarding materials, geometry and lighting. Traditional methods do not offer daylight simulations in real time, whereas interactive visualization requires large computational resources to allow an evaluation of behavior of light in architectural space. This project researched virtual environments that permit the real - time generation of interactive scenes that simulate natural light algorithms modeled. The goal of this is to meet the needs of architects when evaluating the changes of a dynamic and synchronous project.

title	A Breathing Building Skin

summary	This paper details an initial exploration into the development of a breathing building skin. This research proposes a system of diaphragms as an alternative to the use of fans for distributing volumes of air. The driving concepts for this project are the three types of evolutionary adaptation: flexibility, acclimation, and learning. Of particular interest is how these biological concepts relate to architectural design. Parametric modeling was used throughout the project to study a family of folding geometry. This allowed for the iterative development of a complex part that is capable of being manufactured from a single sheet of material. Preliminary calculations point to this system being several times more energy efficient than a fan at moving a given volume of air per Watt of electricity. This research is significant as it puts forth a potentially energy efficient and highly integrated alternative to fans, while also illustrating a way of relating biological concepts of adaptation to architectural design.

summary	In this work, we address the challenges in the realization of free-form architecture and complex shapes in general with the technical advantages of ruled surfaces. We propose a geometry processing framework to approximate (rationalize) a given shape by one or multiple strips of ruled surfaces. We discuss techniques to achieve an overall smooth surface and develop a parametric model for the generation of curvature continuous surfaces composed of ruled surface strips. We illustrate the usability of the proposed process at hand of several projects, where the pipeline has been applied to compute NC data for mould production and to rationalize large parts of free-form facades.
