title	Thermal Simulation In Residential Building Within Computer Aided Architectural Design: Integrated model
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. 235-243
summary	Nowadays, the architectural profession is seeking a better energy saving in the design of buildings. The fear of energy shortage in the very near future, together with the rapid rise in energy prices, put pressure on researchers on this field to develop buildings with more efficient heating systems and energy systems. This work is concerned mainly with the development of a software program analyzing comfort in buildings integrated in CAD architectural systems. The problem of presenting the computer with information concerning the building itself has been overcome through integration of thermal analysis with the building capabilities of CAD system. Mainly, such experience concerns the rules for calculating heat loss and heat gain of buildings in Algeria, The program has been developed in order to demonstrate the importance of the innovation of the computer aided-architectural-design field (CAAD) in the technology of buildings such as the three dimensional modeling offering environmental thermal analysis. CAAD is an integrated architectural design system which can be used to carry out many tasks such as working drawings, perspectives and thermal studies, etc., all from the same data. Results are obtained in tabular form or in graphical output on the visual display. The principle of this program is that all input data should be readily available to the designer at the early stages of the design before the user starts to run the integrated model. Particular attention is given to the analysis of thermal aspects including solar radiation gains. Average monthly energy requirement predictions have been estimated depending on the building design aspect. So, this integrated model (CAAD and simulation comfort) is supposed to help architects to decide on the best options for improving the design of buildings. Some of these options may be included at the early design stages analysis. Indications may also be given on how to improve the design. The model stored on CAAD system provides a valuable data base for all sort analytical programs to be integrated into the system. The amount of time and expertise required to use complex analytical methods in architectural practice can be successfully overcome by integration with CAAD system.

title	Parametric Modelling of Architectural Surfaces
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 635-644
doi	https://doi.org/10.52842/conf.caadria.2009.635
summary	Parametric modelling is gaining in popularity as both a fabrication and design tool, but its application in the architectural design industry has not been widely explored. Parametric modelling has the ability to generate complex forms with intuitively reactive components, allowing designers to express and fabricate structures previously too laborious and geometrically complex to realise. This allows designers to address a project at both the macro and micro levels of resolution in the governing control surface and the individual repetitive component. This two level modelling control, of component and overall surface, can allow designers to explore new types of form generation subject to parametric constraints. Shading screens have been selected as the focus for this paper and are used as a medium to explore form generation within a given set of functional parameters. Screens can have many applications in a building but for the purpose of the following case studies, lighting quality and passive sun control are the main functional requirement. A set of screen components have been designed within certain shading parameters to create a generic component that can automatically adapt to any given climatic conditions. These will then be applied to surfaces of varying degrees of geometric complexity to be analysed in their ability to correctly tessellate and create a unified screening array true to the lighting requirements placed on the generic component.

title	Drawing Architecture using Manga Techniques
source	Managing IT in Construction / Managing Construction for Tomorrow, CIB W78, Attila Dikbas, Esin Ergen & Heyecan Giritli (eds.), CRC Press/Balkema, Istanbul, Turkey, pp.567-576
summary	Manga is a type of stylised bitonal drawings pleasing in terms of screen variety and tidy lines. In this paper, we present a method to draw architecture, spatial compositions and their details, including colours, textures, and tones, using manga drawing techniques. Given a colour image, such as photography, or drawing, our method finds the optimal solution for screening during the bi-tonal transformation, as well as a set of ideally abstracted line drawings. This offers a novel rendering appearance for the communication of architectural design. In our results we demonstrate successfully that our method generates manga-like drawings from an architectural image that preserve architectural key-elements, such as surface or material properties.

title	Digitizing Architecture: Formalization and Content
source	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, 463 p.
summary	CAAD is constantly provoking and raising many potentials, challenges and arguments in academia, practice, and even in the theory of architecture itself. This process starts with the pedagogy of designing and the ongoing questions such as how much of CAAD should be incorporated in teaching, and ends with digital design technologies and the new emerging questions such as how biologically inspired computational processes alter the form of our architecture and the typical design process. Architecture originates from peoples’ needs and beliefs. The new forms of digital architecture generate debates in terms of various important issues, ranging from emotional and social factors to sustainability and warming climate. The focus area of the conference can be shaped, as follows: considering all these potentials, challenges, and arguments, which we have to benefit from and cope with, are there truly legitimate concerns about the future of our architecture and its content in particular from human and environmental dimensions? Can we develop our own ways of benefiting from the technology that cater to our environment and culture? Can we still see the form of architecture in the traditional way or should we change our perspectives? In other words the conference concentrates on bridging between the new digital form and the traditional human content.

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.

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	Fotografia digital e imagens multi-perspectivas no estudo de sítios históricos [Digital photography and multi-perspective image in the study of historical sities]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The creation of panoramic images for depicting urban landscape is a technique that has its origins in Antiquity. These images, which are known to represent large urban areas from multiple views, can be considered true works of art. Recently there has been a growing interest by some researchers, especially in the area of computer graphics, in the production of multi-perspective images for representing historic sites. However, the focus of these studies has been especially the computational aspects of this process, and there are few studies that address the impact and possibilities of these methodologies in historic preservation and urban planning. Realizing this shortcoming and considering the demand for a perspective more connected to cultural heritage, our proposal is to associate the excellent visual results of the multi-perspective images to the rich possibilities of computer simulation that can provide digital photography. The fact is that in recent years we have experienced technological innovations in the field of computer simulation that far exceeded our expectations. While most surveys of buildings are still based on the use of tape measure, pencil, paper and camera, the computer has become increasingly the main interface between the user and the information and is now the preferred instrument for the production and viewing of images, including the creation of virtual environments. Thus, this work seeks to explore the great potential which seems to exist in the combination of digital photography and the technique of multi-perspective image representation, which may provide new approaches and perspectives for the field of historic preservation. For that, we present a rapid and low cost methodology, developed in recent years, which generates orthophotos and metric multi-perspective images, useful for the analysis of built heritage and historic sites. In addition to that, we will also discuss further possible byproducts of this methodology, among which we could highlight the creation of three-dimensional models, and the analysis of building pathologies in combination with thermal photography. As a case study, we will present a representation of the Rua dos Caetés, a listed historic district in Belo Horizonte (MG), Brazil.

title	Notes on Designing Multi-Display spaces
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 461-470
doi	https://doi.org/10.52842/conf.caadria.2009.461
summary	This research attempts to integrate a new technology–Multi- Display Environment (MDE)–into the design and creation of new architectural spaces–multi-display spaces. The research objective is to formulate a set of design guidelines that advise designers on the effective use of the MDE technology, so that the technology may become a new design element and enables designers to show amplification effects of spaces. Two empirical studies are conducted. Based on the results of empirical studies, a set of multi-display space design guidelines is formulated with three key aspects: scene selection, display allocation and display arrangement. The design guidelines require further validations through practical applications. Nevertheless, the research introduces a new design element for designers to think about the future of architectural spaces with more opportunities and possibilities.

summary	Shape grammars have been used in architecture for analysis and synthesis - in the first case, mainly for the characterization of styles and in the later for the generation of novel compositions. The present research proposes the use of shape grammars for establishing guidelines for the requalification of historical areas that have lost their original characteristics due to improper renovations. In order to develop and test the proposed method, a study was carried out in a small Brazilian town called Monte Alegre do Sul. The town was chosen because its original urban morphology, developed in the XIXth century, is still relatively well preserved, although part of the original façades have been transformed. The objective of the research is to develop a shape grammar to set guidelines for the requalification of the already renovated façades in Monte Alegre do Sul.

title	Preserving memories with digital media: a methodology for the reconstruction of Castelnuovo Village
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 83-92
doi	https://doi.org/10.52842/conf.caadria.2010.083
summary	The historical centre of the village of Castelnuovo (located in Abruzzo, a region in central of Italy) was seriously damaged by the earthquake of the 6th of April 2009. Following the survey by the Civil Protection, all dwellings have been classified as unsuitable for habitation. The village should be either abandoned or totally rebuilt. But which is its value? Is there something worth of being preserved? If observed from a biodiversity point of view, or more precisely from a “cultural biodiversity” point of view, the historical centre possess interesting materials and immaterial characteristics. These qualities constitute real guidelines for a possible recovery project. Since there is not any possibility to make a survey of the inner village because of its destruction by the earthquake, in this research we have decided to use information technology, in order to rebuilt it and study it in a three-dimensional environment. In this paper we describe the theoretical basis, the method of elaboration and the instruments we have used to locate and evaluate the memories that should be preserved in a new project. Starting with a traditional documentation, such as photographs and drawings, we have used a variety of software (graphics editing program, CAD, 3D modeler, videogame 3D-engine), because of the several hypothesis considered.

summary	This paper details a series of preliminary explorations into the concept of kinetic tensegrity grids that can respond to stimuli by changing their shape, porosity, and transparency. The research presented explores double-layer tensegrity grids that utilize 3D “compressed” components. A case study demonstrates their applicability to the formation of sophisticated building envelopes that can actively or passively respond to changes in the environment. A computational form-finding tool is introduced to study design variations in real time. This tool is shown to expand the design spectrum by supporting increased complexity and revealing unexpected design potential. This research is significant as it outlines a practical methodology for conceiving responsive building systems. In particular, it illustrates an approach that synthesizes design concerns with engineering and fabrication goals.

title	From Digital Heritage Documentation to 3D Virtual Reconstruction and Recreation for Heritage Promotion and Reinterpretation: The Case of the iHeritage Project
source	C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, pp. 7-23.
summary	In the last two decades, the digital age Information and Communication Technologies (ICT) development and concerns combined with rapid technology have permitted the dissemination of different digital applications (including digital documentation, virtual reality (VR), augmented reality (AR), mixed reality (MR), digital gaming, and holograms etc.) oriented toward past, present and future communication using digital three-dimensional audio-visual content. Today, we must acknowledge that 3D virtual 3D reconstruction and recreation has become an established way to build, understand, reinterpret, and promote Cultural Heritage (CH). The virtual 3D reconstruction world and multimedia industry are often considered potential marketing channels for World Heritage Sites (WHS) and heritage tourism. 3D digital/virtual reconstruction merges and embodies subjectivity in one process, playing an attractive role in heritage tourism destinations and creating image experiences, providing the first enjoyable interpretation and information for most audiences. Based on the EU-funded iHERITAGE project ICT Mediterranean platform for the UNESCO CH, this paper attempts to examine some insights into constructing the optimistic image of heritage promotion and tourism in the context of CH as it flows through both physical and virtual spaces to give a glimpse of the future of virtual reconstruction. It illustrates the development of the concepts and practice, challenges and opportunities, advantages and disadvantages, and the negative and the positive sides of the related issues of only 3D digital reconstructions, and some issues concerning the ethics based on the International Chartres and Conventions mainly in the field of scientific visualisation, such as the London Charter (2009) and Seville Principles (2011). Finally, as a practical dimension, it presents some representative examples of 3D digital/virtual reconstruction of characteristic monuments of the WHS of Nabataean Petra in Jordan for the first time.

title	Digital Modeling in Traditional Architecture Learning: the method and benefits
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. 153-162
summary	This paper looks at learning from The traditional architecture with the aid of digital 3D modelling aimed to support the process of architectural design in a studio environment where designs can be tested without the practicalities of the real world. The process of architectural design in itself is an unknown phenomenon for new students of architecture, so they look to digital 3D modelling to help them in understanding the vernacular or traditional architecture vocabulary. The question therefore, is how can digital 3D modelling underpin a student’s own design philosophy and experience? Also is there any place for the older students, in making this process more productive? The digital 3D modelling of a sample traditional house in historical Jeddah has allowed for a study and learning from of traditional architecture. Observing students over one semester, it was apparent that a more open critical ability developed in understanding the vernacular or traditional architecture vocabulary. Based on feedback from students, we have developed guidelines and recommendations for teaching traditional architecture with the help of 3D digital modelling technologies. We believe we have improved the quality of the Department's small-group teaching and encouraged students to treat communication and 3D modelling skills as valuable. Our results show techniques of creating 3D digital modelling can be very helpful in teaching the vocabulary of our traditional architecture. Digital 3D modelling in this way seems an ideal tool in traditional architectural education which is presently neglected.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The creation process of a product is a work of immersion and concentration, and is, seldom linear. A primary concept most likely will undergo modifications during the process. In what concerns teaching, a great number of Brazilian higher education institutions act exclusively on the formation of students as specialists in the creation of primary concepts. As for the process of refining an idea, as in prototype production and observation, this phase will only be learned and understood on the job market. Nowadays, new methodologies for digital fabrication put into evidence other strategies resulting from post-industrial production.

summary	Recently we developed a prototype general shape grammar system, called Grammar Environment (Li et al. 2009). It differs from other systems in that it aims to support designers who design with shape grammars. One task of such a system is to support users in editing shapes. The guidelines that we followed in developing Grammar Environment suggested that the shape editing system should both be integrated into the system and be powerful as a drawing tool. This seemed to be contradictory. We decided to make two shape editors: one stronger on integration, the other on drawing power.

doi	https://doi.org/10.52842/conf.caadria.2009.033
summary	Geosemiotics, defined as the study of meaning of placing signs in the material world, concerns the interaction of spatial, individual, social, and cultural contexts. Mobile technology, enabling spatial awareness successfully, has turned our living space into coordinates to broaden geosemiotics study. With interdisciplinary perspectives, there is an emerging potential to integrate the study of mobile spatial interaction and geosemiotics and we address several open issues of geospatial applications in this paper. Since indexicality is the focus of geosemiotics study, we focus on digital indexicalities referring to physical space. Physical indexical signs are usually set by government or organizations rather than individuals, and therefore we propose a new concept to place personal indexical signs in the physical space with mobile devices and augmented reality technology. Overlapped onto the physical world via visual, iconic, and metaphorical methods, what these unique personal semiotics bring is a living space with novel urban landscape and geosemiotics.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	This paper presents a parametric analysis where WWR and color glass was varied to determine their influence in the thermal performance of an office building’s room. Design Builder tool was used to calculate the thermal load and the internal gains. The WWR variation in different orientations resulted in a significant increase of the thermal load. The reflective glass allowed a better thermal performance of the room. With the use of computer simulation was possible to analyse many constructive and design characteristics of the facade and its influence on the results, when considered together.

summary	The aim of the paper is to establish an ontology-based case encoding tool with sufficient formalization and expansibility to assist users for organizing the case information and increasing the feasibility of the design knowledge in a case library. The tool is named Open Case Study (OCS). OCS is a formalized and expandable tool for authoring metadata of a case library and organizing them by their semantic ontology. By using the templates constructed by design experts, such as design teachers or experienced architects, OCS provides the user with explicit but adaptable guidelines for case analysis and encoding. OCS then performs the searching and mapping function provided by Open Ontology. Thus, when the user is encoding the information segments of cases, relevant knowledge chunks in the case library can then be immediately provided, such as relevant senses in similar cases, all atoms of a relevant sense, and known value ranges of a relevant property. This assists users to avoid data mistake and duplication in encoding design cases.

summary	Frank Gehry is a notable contemporary architect. His work method, that it mixes technology and architecture involves varied instruments as the outline and the drawing, the physical model and the tool computacional and it makes possible the execution of architectural objects with specific characteristics. The artistic influences suffered in the beginning of the career, decades of 60 and 70, they were considerable in his way of to notice and to conceive the architecture. Their purposes differ of the ones of most of the architects for if they relate with an artist's concerns: the form as middle of expression.

summary	This essay codifies and extends contemporary conceptions of systemic organization using architectural case studies within the context of 1950’s space-time. Given the dominance of certain concerns within the profession of architecture during that time—prefabrication and strict modularity—the selected case studies reveal unprecedented characteristics which anticipate current developments in algorithmic and parametric formation. The projects in question demonstrate sophisticated strategies for differentiated part-to-whole relationships which predate contemporary organizational systems, now derived with the aid of digital computation. Their importance to current architectural discourse lies in distinguishing the manner in which they manifest notions of space-time, including transformation, continuity and modulation, as architects increasingly operate within dexterous and interconnected environments.
