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.

title	Performative Building Skin Systems: A Morphogenomic Approach Towards Developing Real-Time Adaptive Building Skin Systems
source	International Journal of Architectural Computing vol. 7 - no. 4, 643-676
summary	Morphogenomics, a relatively new research area, involves understanding the role played by information regulation in the emergence of diverse natural and artificially generated morphologies. Performative building skin systems as a bottom-up parametric formation of context aware interdependent, ubiquitously communicating components leading to the development of continually performative systems is one of the multi-scalar derivations of the aforementioned Morphogenomic understanding. The agenda of adaptations for these building skins specifically corresponds to three domains of adaptation: structural, behavioral and physiological adaptations resulting in kinetic adaptability, energy generation, conservation, transport and usage principles as well as material property based changes per component. The developed skins adapt in real time via operating upon ubiquitous communication and data-regulation protocols for sensing and processing contextual information. Computational processes and information technology based tools and techniques such as parametric design, real-time simulation using game design software, environmental information mapping, sensing and actuating systems coupled with inbuilt control systems as well as manufacturing physical models in collaboration with praxis form a vital part of these skin systems. These experiments and analysis based on developing intrinsic inter-dependencies between contextual data, structure and material logistics thus lay the foundation for a new era of continually performing, self powering, real-time adaptive intelligent building skin systems.

title	Dynamic Relaxation of Tensegrity Structures
doi	https://doi.org/10.52842/conf.caadria.2009.553
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 553-562
summary	The structural hierarchy inherent to tensegrities enables a building skin that performs on multiple levels simultaneously. While having one function in the global building mechanics, its individual components can work as self-contained systems balancing tensile and compressive forces locally within them. The behavior of elements under load is linear and thus describable analytically. When these are aggregated in a tensegrity however, the performance of the assembly as a whole is non-linear. In order to investigate further these relationships a method of dynamic relaxation will be developed. This tool allows for simulation and load analysis of a complex tensegrous network, based on the relationships between force, stiffness and dimension formulated by Young and the computational means provided by a parametric/associative modeling environment. This research investigates the possible formfinding through computational means of a double-layer tensegrity grid.

title	Visual sensitivity analysis of parametric design models: Improving agility in design
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 815- 829
summary	The advances of generative and parametric CAD tools have enabled designers to create designs representations that are responsive, adoptable and flexible. However, the complexity of the models and limitation of human-visual systems posed challenges in effectively utilizing them for sensitivity analysis. In this prototyping study, we propose a method that aims at reduction of these challenges. The method proposes to improve visually analysing sensitivity of a design model to changes. It adapts Model-View-Controller approach in software design to decouple control and visualization features from the design model while providing interfaces between them through parametric associations. The case studies is presented to demonstrate applicability and limitation of the method.

title	Contemporary Digital Methods for the Geometric Documentation of Churches in Cyprus
source	International Journal of Architectural Computing vol. 7 - no. 1, 21-37
summary	Recent advances in digital methods incorporating information technology have enabled the traditional surveyor and monument recorder to work faster, more accurately and in an automated way in order to produce advanced digital products, more versatile and more useful to the end users. Such methods include tacheometry, digital photogrammetry, as image-based method, terrestrial laser scanning and the development of specialized software in order to fully exploit the digital data acquisition. Usually, a combination of these methods gives the most efficient cost benefit results, by providing 2D vector and raster products and 3D textured models. In this paper two examples of the implementation of these methods in the geometric documentation of two churches, both significant for the history of Cyprus, are presented. It is concerned with the churches of Virgin Mary (Panayia) Podithou, in Galata and St. George Nikoxylitis in Droushia. The applied methodology, using classical and contemporary techniques of commercial and in-house developed software is presented. Comparative tests for the achieved accuracies and the completeness of each method's products have been made, and their merits and usefulness are explained.

title	TetraScript: Sistema integrado para optimizar a iluminação natural num espaço circunscrito [TetraScript: An Integrated System to Maximize the Natural Light in a Confined Space]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The purpose of this research is to develop a process capable of optimizing the capture of light in a circumscribed space, using a responsive system of skylights. Research is focused on the design of irregular dome-like pavilion spaces but the envisioned process might be applied to other functional, formal, and spatial typologies. A process based on scripting generates a matrix of components based on geographic situation, and sun orientation. The integration of conception and fabrication with digital tools (CAD-CAM) enabled the construction of this non standard, parametric geometry, diminishing the costs of production, allowing personalization and assuring global sustainability.

summary	This paper will relay the initial phase of a collaborative work within partners from the design discipline, systems engineering, and software engineering which deals with the interrelations of “network idea”, “systems thinking”, “collective design”, and “computation”. Vensim– a system dynamics modelling tool developed by Ventana Systems, Inc. in 1992 – has been used in an experimental first year design studio to engage students in systems thinking in the architectural design environment. It has been observed that this tool enabled most students to develop a multi-layered, complex and more controlled design logic and to amplify the cognitive processes at the beginning of the design education. We conclude that in order to fully realize systems thinking in the design process, new ways of integrating parametric design environments and system dynamic modelling environments needs to be investigated.

title	A Cyber-Enabled Collaborative Design Studio
source	International Journal of Architectural Computing vol. 7 - no. 2, 267-288
summary	The research project investigates the use of a network-enabled platform involving a combination of technologies. As a preliminary report on a proof-of-concept design studio conducted in 2007 between Carleton University and Pennsylvania State University, the paper first describes the implementation of this network-centric collaborative design platform. The report articulates the “staging” of the conditions of possibility for a dynamic interplay between technological mediation and the reality of making, then compares the use of high bandwidth technology with customized symmetrical toolsets in the telecollaborative environment, versus commercial toolsets deployed over moderate bandwidth connections. In each setting, the collaborative environment is assessed according to issues encountered by students and design outcomes. The effectiveness of the digitally mediated collaborative studio is also gauged in terms of student reaction to the learning process via feedback surveys and questionnaires.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	It is appropriate to investigate the potential analogies between architecture and biology enabled by the use of digital processes, thereby testing the effectiveness of the application of biological principles to the lifecycle of buildings. The aim of this paper is to understand the way architects integrate and develop different biological approaches to architecture, by mapping the present situation and identifying the trends for future developments. Three major approaches were identified: biomimetics, bionics and biotechnology. The use of biological knowledge and technology in architecture, could pave the way for solutions to current problems, such as energy shortage, climate change, and lifestyle diversity.

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	BIM in academia: Shifting our attention from product to process
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 395-409
summary	This paper proposes changes in architectural education to respond to BIM technology and the resulting complexity in the design concept. We examine the interoperability issues between design and analysis in professional practice. We present the results of a case study mapping the activities of two interdisciplinary student teams in the early design phases of a BIM-enabled project. Results show the problems associated with building simulation tools, core knowledge lacking in architectural education, and the relationship between information management, team process, and the types of tools used. A flexible curricular structure is proposed in architectural education, expanding our professional roles.

title	Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.
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. 451-476.
summary	The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building‚Äôs Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

title	Depth Perception in Real and Pictorial Spaces: A Computational Framework to Represent and Simulate Built Environments
doi	https://doi.org/10.52842/conf.caadria.2009.543
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 543-552
summary	Architectural design is often mediated on two-dimensional representation systems and envisioned three-dimensionally in the pictorial space. The developments of advanced digital technologies have enabled us to create the pictorial representations of un-built design projects that can appear as real as photographs. The visually appealing pictures produced by photorealistic rendering tools are useful for visualizing the form and the spatial layout of the proposed architectural design; but they may be inadequate and misleading for simulating the perceptual qualities of space. This paper draws from the recent developments in computer graphics (physically based renderings and perceptually based tone mapping techniques) and proposes a computational framework to faithfully represent and simulate pictorial spaces. Guidelines are provided for generating images with appropriate representation and simulation techniques so that architects can make informed design decisions about the perceptual qualities of their designs and researchers can study depth perception in computer environments.

title	Redesigning The Brick
doi	https://doi.org/10.52842/conf.caadria.2009.381
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 381-390
summary	This research examines the value of “redesigning the brick,” in creating a new vocabulary of basic architectural building blocks with autonomous reconfigurable robotics. The paper highlights several built examples by the author of robotic architectural environments and the work of architecture students whereby individual modules were created within the context of a design studio and applied to scenarios of space making at various scales. Several strategies for decentralized control were explored dictating how individual parts of a system should behave and how local interactions between individual modules can lead to the emergence of global behaviour. The students schematically designed selfreplicating models which would allow for each object to be able to attach, detach, and reconfigure according to predetermined computational logic. The projects successfully demonstrate various strategies for mechanical design, locomotion and control.

summary	InteractiveChair is proposed as a natural and affordable medium that enables direct control of locomotion in 3D virtual space by using dynamic sitting postures. InteractiveChair detects subtle movements of a chair occupant in real time by measuring relative position and orientation between the user’s body and the chair. While standard user interfaces require users to consciously relate the device manipulation by hand to the action in the virtual space, InteractiveChair directly leverages the correlation between our body and spatial conception to control the avatar’s locomotion. This study determines typical user behaviours on the chair and measures them through sensors that are exquisitely integrated with a typical swivel chair. The study then presents results from a user study to measure the qualitative factors of user experience in controlling virtual locomotion with InteractiveChair.
