summary	This paper describes a prototype of an intuitive tool named Smart Topology for the architectural space allocation in the early design phase. Smart Topology focuses on the manipulations of virtual spaces and can build and operate the topological relation among them by instantly modifying the geometric properties of spatial allocation so as to comply with the topological relation defined by the user. Based on a prototype of an interactive tool for the spatial allocation named Spatial Layout Game (SLG), Smart Topology adds more topological operations into SLG, such as the connective, combining, orientating, and opening. It also tracks the manipulating process and results by applying the database technology.

title	Experiments with stochastic processes: Facade subdivision based on wind motion
source	International Journal of Architectural Computing vol. 7 - no. 3, 389-402
summary	Constraint based tools for architectural design exploration need to satisfy aesthetic and functional criteria as well as combine discrete and continuous modes of exploration. In this paper, we examine the possibilities for stochastic processes in design space exploration. Specifically, we address the application of a stochastic wind motion model to the subdivision of an external building envelope into smaller discrete components. Instead of deterministic subdivision constraints, we introduce explicit uncertainty into the system of subdivision. To address these aims, we develop a model of stochastic wind motion; create a subdivision scheme that is governed by the wind model and explore a design space of a façade subdivision problem. A discrete version of the façade, composed of light strips and panels, based on the bamboo elements deformed by continuous wind motion, is developed. The results of the experiments are presented in the paper.

title	Sound fields; experiencing the unrepresentable
source	6th AHRA Conference, 20-21 Nov. 2009
summary	This paper explores the intangible aspects of space through a series of soundmappings that took place in Edinburgh and Athens between 2006-08. One of our main conclusions is that sound is a rich and provocative tool for exploring space, due to the fact that it reveals qualities and information that a visual representation wouldn’t had been able to. A significant remark we made is that the exploration of space through sound does not predetermine the findings; we did not pose questions about pre-decided aspects of the places under investigation. On the contrary, within each different environment, the study of sound brought out different kinds of information. We also realized, that the experience of sound of a place lies in the tension between our attempt to grasp, and possibly map it, and the fact that sound – and atmosphere in general – naturally resists these endeavours.

title	Preliminary tectonic phenomena of diversified architectural spatial forms in digital age
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 599-608
doi	https://doi.org/10.52842/conf.caadria.2010.599
summary	The research on tectonics in the architectural field began from the middle of nineteenth century and in recent twenty years digital technology gradually developed and permeated through the field of architecture. Liu and Lim (2006, 2009) integrated classic and digital tectonic factors a present framework of new tectonics. However, the previous studies related to the tectonics in this digital age were only on architectural cases that use a great deal of digital media. The research wants to know what and how the tectonic factors affect the different spatial forms of modern architecture and focused on a case study of the diversified spatial forms, orthogonal, folding and curving. The results show the classic tectonic thinking is imperative until now. It is critical to prove the significance of adding the new digital tectonic factors in digital age.

summary	The materialization of architectural forms uses new processes aided by digital manufacturing techniques (FD). Five FD techniques stand out: sectioning (serial planes), tessellation, folding, contouring, and forming. This article's objective is to characterize the state of the art of these techniques, from 2009 to 2020 in national and international research bases. The Systematic Literature Review is used from three stages and nine protocol phases. The results indicate the techniques, methods, computer simulations, and applicability in more recurrent materials.

title	Designing for the unpredictable: Novel model for the design of emergence through real-world behavior
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 847- 860
summary	Most current approaches to unpredictability, within architectural discourse, lie either in the design of unbuildable emergent shapes or in performance simulations to test already designed outcomes. Even though some recent explorations have enabled the construction of emergent shapes, the unpredictability of real-world behaviors as the rules’ source for the unpredictability of shape generation remains unexplored. This paper proposes a novel model for the design of unpredictable buildable shapes, based on real-world behaviors. Initially, current methodologies are studied in order to find how they deal with the unpredictability of shape generation and real-world behaviors. Finally, a comprehensive novel model is proposed and tested through an empirical experiment, to show how it can be applied in architecture.

title	Novel Transformations of Foldable Structures
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 195-204
doi	https://doi.org/10.52842/conf.caadria.2009.195
summary	Most foldable structures have been designed to optimize collapsibility and structural performance. Likewise, they have been solely applied to a limited number of architectural shapes such as arches, domes or geodesics. While the constant folding process between retracted and deployed states, has been the main concern of designers, non-constant transformations and the in-between states remains unexplored. This research will study non-constant transformations in the in-between states, with the aim to find novel shapes and extend the repertoire of current applications. Initially, existing structures will be modified in order to find what type of shape transformations can be produced. Finally, a novel solution, through a digital model and a kinetic physical prototype, will be proposed.

title	From texture to volume: an investigation in quasi-crystalline systems
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The relation between texture, pattern and massing is a fundamental question in architecture. Classical architecture, as Leon Battista Alberti states in “De re aedificatoria” (Book VI, Chapter 2), is developed through massing and structure first; texture is added afterwards to give the bold massing and structure beauty. Only the ornamentation adds pulcritudo to the raw structure and massing. Rather than starting with a volume and applying texture afterwards, the Digital Girih project started with textural operations that informed the overall volume later. The stereometric, top-down methodology is questioned through the bottom-up methodology of the Girih project. Girih lines of traditional Islamic patterns were used as a starting point. The aspect of 3-dimensionality was developed analogue as well as digital, using the deformability of different materials at various scales and digital construction techniques as parameters. The flexibility within the Girih rules allowed the system to adapt to different tasks and situations and to react to different conditions between 2- and 3- dimensionality. The project in that way explored a bottom-up process of form generation. This paper will describe the process of the project and explain the necessity of digital tools, such as Grasshopper and Rhino, and fabrication tools, such as laser cutter and CNC fabrication technology, that were essential for this process.

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.

title	Human visual perceptions in built environment: Applying image-based approach for architectural cue recognition
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 328-341
summary	This paper first presents a review on visual perception in the built environment and human vision simulation. Followed by the description of the Standard Feature Model of visual cortex (SFM), an architectural cue recognition model is proposed using SFM-based features. Based on the findings of the experiments it can be concluded that the visual differences between architectural cues are too subtle to realistically simulate human vision for the SFM model.

summary	This article presents an application of Augmented Reality technology for interior design. Plus, an Educational Interior Design Project is reviewed. Along with the dramatic progress of digital technology, virtual information techniques are also required for architectural projects. Thus, the new technology of Augmented Reality offers many advantages for digital design and construction fields. AR is also being considered as a new design approach for interior design. In an AR environment, virtual furniture can be displayed and modified in real-time on the screen, allowing the user to have an interactive experience with the virtual furniture in a real-world environment. Finally, this study proposes a new method for applying AR technology to interior design work, where a user can view virtual furniture and communicate with 3D virtual furniture data using a dynamic and flexible user interface. Plus, all the properties of the virtual furniture can be adjusted using occlusion based interaction methods for a Tangible Augmented Reality.

title	Monitoring Archaeological Site Landscapes in Cyprus using Multi-temporal Atmospheric Corrected Image Data
source	International Journal of Architectural Computing vol. 7 - no. 1, 121-138
summary	This paper aims to examine the use of satellite remote sensing for monitoring archaeological and more generally cultural heritage sites. For this purpose, multi-temporal data from Landsat 5 TM, Landsat 7 ETM+ and Quickbird images were applied. The paper also discusses the importance of atmospheric correction at the pre-processing step in order to determine true surface reflectance values by removing these effects from satellite images. Atmospheric correction is arguably the most important part of the pre-processing of satellite remotely sensed data and any omission produces erroneous results. The effects of the atmosphere are more severe where dark targets are shown in the satellite image. In the management of cultural heritage sites, since temporal satellite images are required for monitoring purposes, the effect of the atmosphere must be considered. In-situ spectro-radiometric measurements using the GER1500 field spectro-radiometer have been used to assess the reflectance values found after applying the darkest pixel atmospheric correction to the image data. The study area consist the Amathus archaeological site in Limassol and the Nea Paphos archaeological site area located in Paphos district area in Cyprus. Vegetation Index (NDVI) change detection algorithm has been applied to a series of thirteen Landsat TM/ETM+ images of Amathus archaeological site in Limassol. Classification and extraction algorithms have been applied to Landsat TM and Quickbird high resolution images of Nea Paphos archaeological site area.

title	Systems-Thinking: Formalization of parametric process
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. 215-223
summary	This paper details a design process focused on explicit digital parametric modeling as an integral system-outcome design. This investigation isolates and alters a simple geometric form (cylinder) in a constructed architectural design method. Systems are defined as logical, sequential operations inherent to the resultant effects. These operations within each system are composed of various parameters, singular entities containing or referencing data. Given specific data, operations are preformed culminating with corresponding outcomes. The two main components of this research pertain to object extraction and transformation. A single grain silo (cylinder), as the architectural/geometric object under examination, is tested using a system of varied parameters inputted into the program Grasshopper, an “explicit history” graphic plug-in for Rhinoceros. This application is utilized to digitally manipulate parameters as objects in a nodal arrangement. Throughout the operations execution, this isolated silo will be transformed into a multitude of versions, then regrouped into the original cluster of silos to expose the implications from patterning, adjacency, and repetition given the proximity of the each silo and its new parametric characteristics. As the various parameters in specific operations affect the system as a whole, so is each adjacent silo in proximity given the same or similar operation? This then is translated and reflected in the outcome. This research seeks to explore design process by applying constant digital 3-D reductive geometric, modular forms inviting systems thinking in parametric environments that can lead to architectural design implications. By focusing on the technical aspect of the parameterization and valuing functionality rather then style, the process becomes focused on formal qualities as the system-outcome relationships. This research tests the “aesthetic implications” of a varied mode of digital design, namely the investigation of an architectural process utilizing parametric design.

title	Using the FBS ontology to capture semantic design information in design protocol studies
source	in J McDonnell and P Lloyd (eds), About: Designing. Analysing Design Meetings, CRC Press, pp. 213-229.
summary	This chapter presents a method to capture semantic information from design protocols. We report on a preliminary study that analyses a design protocol by using the FBS ontology and derives processes within this ontological framework by employing linkography. The usefulness of this method is examined by applying it to the Engineering 1 protocol (E1) as a case study. The original 1990 FBS ontology captures 66% meaningful processes of all the derived processes, while the situated FBS ontology captures 92% meaningful processes of all the derived processes. Further coding analysis may improve this percentage. The session is characterized, according to the ontology, by the high percentage of behaviour reformulation, followed by structure reformulation, and analysis.

title	The Design of a Mobile Navigation System Based on QR Codes for Historic Buildings
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 103-112
doi	https://doi.org/10.52842/conf.caadria.2009.103
summary	Due to the rapid development of mobile and compact electronic devices such as PDAs and smart phones, designers and developers now have to consider user mobility and the dynamic context of use in the design of interactive systems. In this study, literatures associated with mobile navigation systems in museums and historic buildings are first reviewed in order to understand the features, advantages, and drawbacks of current mobile navigation technology. The feasibility of applying QR codes in the navigation of historic buildings is then discussed, and the mobile navigation principles mentioned in previous literatures are applied in our proposed system. A number of common problems are encountered in the navigation of local historic buildings or museums. Visitors (1) cannot understand what makes an exhibited item a work of art; (2) do not know where to start or how to get started; (3) feel rushed by guides during the guided tour; and (4) find that the audio guide is not clear enough. Managers of historic buildings or museums are generally concerned about (1) the high cost of constructing a mobile navigation environment; (2) possible damage to devices; and (3) the cost of device maintenance. This study attempts to solve the above issues by constructing an affordable digital navigation environment that enables users to clearly understand each exhibited item and its location.

title	O Uso de Modelagem Generativa para Representação de Modulações de Alvenarias em Ferramentas BIM
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	One approach to perform the design for production of masonry with BIM tools is to explicitly represent the wall elements. However, this strategy decreases the application performance because of model complexity. Generative Modeling is a modeling paradigm aimed at defining rules and applying them for generating models. The masonry block placement is associated with a set of rules, making the use of generative modeling a viable solution to implicitly represent the blocks. This paper presents some preliminary results of our research on investigating if Generative Modeling can help in the representation of masonry modulation and for the proposal of a shape grammar for representing its basic elements.

summary	This study evaluated the BIM Maturity Levels of architecture offices in Porto Alegre (Brazil) by adapting the method developed by Succar (2009). It was carried out by applying a questionary in face-to-face interviews and converting the qualitative data obtained into quantitative, ultimately generating the BIM Maturity Index: a percentage number that can be classified and compared. The preliminary results indicate a significant discrepancy in BIM competences between the case studies while reasserting challenges faced by them in a regional scope: the scarcity of external stakeholders appropriately inserted on the BIM process and the undersupplied BIM knowledge offered in academic courses.

summary	Past research over the last two decades has demonstrated that fractal analytical methods can be used to evaluate the visual complexity of architectural designs. Applying a computer program that has been developed specifically for the quantitative evaluation of architecture, the authors previously tested the fractal analysis method on several well-known architects’ works including those of Le Corbusier. However, while undertaking this research the computational method revealed unexpected results for the visual complexity of Le Corbusier’s early, highly ornamented, house designs. This paper examines these anomalous results and the proposition that they are a by-product of the data chosen for analysis. The fractal method relies on architectural drawings as raw “data” but little research has been undertaken into which elements should be chosen to represent the buildings or alternatively, which lines are “significant”. The present paper uses the results for ten of Le Corbusier’s house designs to examine the sensitivity of the method.

source	27th eCAADe Conference Proceedings [ISBN 978-0-9541183-8-9], Istanbul (Turkey) 16-19 September 2009, 854 p.

summary	In the field of architecture, computational design has emerged as sub-discipline having a multidisciplinary nature and using computing methods and capabilities to understand and solve architectural design problems. Computational design is based on computational thinking that includes a range of mental tools in solving problems, designing systems, and understanding human behavior. It has drawn on the concepts of mathematics and computer science. Computational design elements are derived from both theoretical science and experimental design in such a way that its mechanism relies heavily on mathematical logic, but once built, experimentation is done by varying one parameter at a time to study individual changes. It is a design model, not design itself. Computational design involves applying appropriate computational mechanisms, algorithms, or methods to architecture in order to solve design problems and develop design applications. This process creates systems that can be used as design tools for exploring and forming entirely new design concepts and strategies. Over the next decade, computation will have a great impact on design world. It will solve more complex design problems with greater accuracy and be applied by more designers more routinely—it will go deeper and wider. However, the greatest change that it will bring is the breaking down of barriers between scientific domains and design, enabling real “design science.” Computation is already a key driver in “joined-up” research. It forces scientists and designers to think deeper and wider. Some people have considered it to be the enemy of creativity. In their opinion, designers simply must do things rather than think about what they are doing and how they are doing it. Deeper thinking is associated with scientific rather than designer thinking. The fact is that some of the most innovative and creative work is being done by people who have developed computational thinking skills and know other disciplines along with computing. The theme of eCAADe 2009 conference, Computation: The New Realm of Architectural Design, is devoted to exploring the ramifications of this view for the domain of design: research, education, and practice. We believe that the most intriguing research questions that will emerge from the advent of new and more powerful computational devices—and from the design tools that make use of them—will be in the realm of developmental design science.

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.
