title	Algorithmic Form Generation of a Radiolarian Pavilion
source	International Journal of Architectural Computing vol. 7 - no. 4, 677-688
summary	This paper describes the design stage of an on-going research project for the construction of a pavilion that mimics the bone structures of Radiolarians. In the process, several constructive and generative algorithms are developed, together with geometric and trigonometric functions, all implemented in RhinoScript and a math plug-in for the NURBS modeler Rhinoceros. There has been considerable emphasis on the generation of the Radiolarian cell that is tessellated along a stereographic surface with a honeycomb-based algorithm. It combines design strategies from biomimetics, mathematical functions, generative scripting, process automation and versioning, all integrated into an algorithmic methodology for creating a non-standard structure, capable of being manufactured with CNC technology, and doing so, setting a precedent in the academic and professional environment in which it will be located.

title	Pluripotent Structures: An Exploration into Digital Design & Fabrication by Bio Mimicry
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 665-668
summary	This project is an exploration into the design & fabrication process of a canopy structure derived from the notion of pluripotency. The term is widely used in the context of stem cells in biological science where pluripotency is referred to the potential of a stem cell to develop into more than one type of mature cell, depending on environment. These can be re-interpreted architecturally as, the quality of design components or elements to be radically transformed into one or more different kinds of components, keeping the general structural integrity of the design unchanged (Kolatan, 2009). Consequently, the pluripotent canopy design is a 3 dimensional double curved surface , having smart pluripotent components populated over its domain, which parametrically has the potential to be transformed to more than one different kinds of elements, keeping the same parameters of construction for each component.

title	Decon Recon: Parametric CADCAM Deconstruction Research

summary	The deconstruction (DeCon) and repurposing (ReCon) of existing structures and materials are worthwhile and relevant endeavors given the potential for such procedures to be more economically and environmentally sustainable than conventional construction methods. Conventional construction methods often utilize virgin materials for the production of architecture, requiring extensive energy to harvest, process, and manufacture the materials for use. Today, we must face the fact that we exist in a carbon-sensitive economy, and demand design approaches that reduce architecture’s impact on the environment. Our goal was to develop a CADCAM ReCon design methodology that would have the potential to mitigate carbon consumption. To explore this goal, students engaged a design research project that looked for novel and innovative approaches to the DeCon and ReCon of an existing barn. The student researchers created parametric models and surface designs derived from the existing materials. The digitally fabricated tectonic design constructions resulted in economical, novel, and material-efficient design methodologies for DeCon and ReCon.

summary	Tensegrity grids composed of tensegrity units that form double layer cable nets of single or double curvature can find applications in architecture as surface structures. In this paper a parametric process for the geometric configuration and representation of double layer tensegrity structures of helical shape is discussed. Departing from the geometric construction process, an algorithm that facilitates the parametric description of helical tensegrity structures has been developed. The algorithm reflects the interdependence of all parameters involved in the design of helical tensegrity structures and has been integrated into a software application that enables the automatic generation of virtual models of helical configurations in a graphic environment.

title	Bio-shell (Biodegradable vacuum-formed modularized shelter)
source	T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary	This poster demonstrates how digitally fabricated vacuum-formed components can provide a new type of lightweight construction applicable to architecture. Surface-active systems such as a thin-shell concrete domes are some of the most material-efficient structures. Despite their efficiency few have been constructed recently due to necessary extensive labor cost. However, the growing concern for a worldwide shortage of natural resources and rising material costs, suggests that we reconsider the use of efficient structures, such as surface-active systems. Vacuum formed plastics mainly used in industrial design have strong merit based on their fast and low-cost mass production. Together with the recent emergence of digital fabrication technologies, the vacuum forming process is becoming an attractive fabrication technique for new and innovative lightweight structures.

title	Musical Deconstruction / Reconstruction: Visualizing architectonic spaces through music
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. 225-233
summary	There is a common belief that music and architecture are connected through a hidden a dimension. Both arts, when abstracted intellectually (through mathematics) or emotionally (through phenomenological experience), share a number of ordering principles, having the same notion of crescendo in sequence and progression. Many have sought to unlock this hidden dimension to create artwork that lets our souls transcend up to the heavens. There are five different methods where architects have used music in their design approach: there are those who use harmonic proportions found in musical consonances as room dimensions to create harmonic spaces, flowing into each other like musical chords (Palladio, Steven Holl); those who believe that music is ‘design in time’ use rhythmic elements of music and apply it to their vertical surfaces and structural grids (Iannis Xenakis, Le Corbusier); those who use architecture as a musical instrument experiment with sound and acoustics to create a phenomenological environment (Bernhard Leitner, Peter Zumthor); those gifted with synethsesia (stimulating one sensory preceptor with another, e.g. seeing colors by listening to music, or vice versa) use certain musical pieces as an inspiration for form generation (Wassily Kandinsky, Steven Holl); and there are those who deconstruct an element in music and reconstruct it to architectural form, highlighting common themes between both arts (Iannis Xenakis, Daniel Libeskind). These five different methods have been the topic of research of many architectural scholars using western music as reference. The question becomes what if the musical reference is changed? Classical, rock, pop, country, jazz, and blues music are very different from one another, yet they share similar foundational musical structures. One may go further and experiment with various world music as reference, which is very different than western music in terms of musical structure. Linguists and musicologists have discussed the origins of music in relation to language. They hypothesize that cognitive elements found in language are somehow carried into the region's music. This paper documents the research of the author in this topic, discussing the digital modeling applications adopted that make such an investigation possible. The interest here is exploring how the visual space is altered when the musical reference is changed, and whether properties of the musical reference are evident in the architectural visualization. The musical references will be limited to Western Classical and Arabic music.

summary	In the summer of 2018, our collaboration was awarded a University Design Fellowship from the Exhibit Columbus organization to design, fabricate, and build a large pavilion in Columbus, Indiana as part of a biannual contemporary architecture exhibition. Our proposal for the competition was a pavilion that would double as an ecological education center. Our inspiration for this program was triggered in part by our reading of Jane Bennett’s materialist philosophy outlined in her book Vibrant Matter (2009). Through Bennett’s lens, our design rendered our site’s context as an animate field, replete with pre-existing material composites that we wanted to celebrate through a series of displays, information boards, and artificial lighting. In this, the installation would feature samples of local plants, minerals, and rocks, indigenous to Southern Indiana.

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

title	Modulations of Voxel Surfaces Through Emotional Expressions to Generate A Feedback Loop Between Private Mood and Public Image
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 173-182
doi	https://doi.org/10.52842/conf.caadria.2009.173
summary	My proposal is an investigation into the perceptual boundaries between human and architectural expression. It asks how architecture can creatively adopt human expression by using the emotions ‘displayed’ on the ‘surface face’ as a generator for displaying a surface on a voxel façade to achieve a cross-connecting perceptual change with modulations through emotion (Massumi, 2006). Through voxel facades the public with their expressed emotions will be included in the decision process of defining space, by expressing our innermost feelings through an architectural medium. Thus emotions of the individual have a platform and can be conveyed indirectly to the public, and in turn open up discussions about the state of the community through the state of the façade. An alliance of media and place in an urban context can be achieved and created, with the participation of its inhabitants, along with a new perception of how media and architecture can together shape and inform spatial relations for a feedback loop between private mood and public image.

summary	The way screens are attached to architecture at present limits architectural surfaces to carriers of signs. The research presented in this paper offers a possible solution that allows architectural surfaces to be both a space-defining element that has certain architectural material qualities and at the same time allows media technology to be embedded. These surfaces can alter their state from static material to dynamic image in an instance. The paper presents a prototype capable of fulfilling this requirement. It also positions the research within the architectural discussion by comparing it to works of others and confirming its research value by reference to work in a similar direction. Finally, the paper evaluates the research and concludes that it could offer a ‘fabric’ to be used as a sort of media clothing for architecture in the electronic age (Ito, 2001).

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 circumscribed by curved surfaces, but the envisioned process might be applied to other functional, formal, and spatial typologies. The design of the pavilion starts with the generation of a surface, later tessellated into a matrix of skylights depending on the geographic location and sun orientation. In the constructed pavilion, the skylights react to the variation of daylight intensity during the day to satisfy specified internal lighting needs. Simultaneously, the integration of conception and fabrication using digital tools (CAD-CAM) facilitates the construction of a non-standard, parametric geometry, thereby diminishing the costs of production and allowing for personalization, while assuring global sustainability.

title	Towards a dynamic evacuation system: developing methodologies to simulate the evacuation capabilities of subway stations in response to a terrorist attack with CBRNE weapons
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 109-118

summary	Events in recent times have highlighted the vulnerability of underground public transportation to possible terrorist attacks. A key question therefore is how an evacuation can be accomplished from underground stations safely. The strategy “go up and take the nearest exit to the surface” might not be the best response. Evidence from the Daegu subway station fire in 2003, investigated by Tsujimoto (2003) and Jeon and Hong (2009) establish that smoke or toxic airborne substances from a terrorist attack tend to use the same direct routes used by the fleeing passengers and as result significant injuries or fatalities can occur. This study proposes the concept of a dynamic evacuation system which would guide subway users along safe routes. To test how this system may operate, the study discussed combines measurements from tracer gas experiments with climate measurements to establish how toxic agents spread in subway stations under certain conditions and combines these results with those from pedestrian simulations applied to calculate evacuation times for possible escape routes. By integrating the resulting dataset from these methods, an evidence base of how a dynamic evacuation system may work can start to form.

title	Performative Wood: Integral Computational Design for Timber Constructions

doi	https://doi.org/10.52842/conf.acadia.2009.066
summary	Wood differs from most building materials in that it is a naturally grown biological tissue. Thus wood displays significant differentiation in its material makeup and structure as compared to most industrially produced, isotropic materials. Upon closer examination wood can be described as an anisotropic natural fiber system with different material characteristics and related behavior in different directions relative to the main grain orientation. Because of its differentiated internal capillary structure wood is also hygroscopic. It absorbs and releases moisture in exchange with the environment and these fluctuations cause differential dimensional changes. In architectural history the inherent heterogeneity of wood and the related more complex material characteristics have been mainly understood as a major deficiency by the related crafts, timber industry, engineers and architects alike. This paper will present an alternative design approach and associated computational design tools that aim at understanding wood’s differentiated material make up as its major capacity rather than a deficiency. Along two design experiments the related research on an integral computational design approach towards unfolding wood’s intrinsic material characteristics and performative capacity will be discussed. The first experiment explores the anisotropic characteristics of wood by exploiting the differential bending behavior in relation to the local induction of forces through which a specific overall morphology can be achieved. The second experiment focuses on the hygroscopic property of wood as the base for developing a surface structure that responds to changes in relative humidity with no need for any additional electronic or mechanical control.

doi	https://doi.org/10.52842/conf.acadia.2009.075
summary	Aperiodic tiling patterns result in endlessly varied local configurations of a limited set of basic polygons, and as such may be used to economically produce non-repeating, complex forms from a minimal set of modular elements. Several well-known tilings, such as by Penrose (2D) and Danzer (3D), have been used in architecture, but these are only two examples of an infinite set of possible tilings that can be generated by the projection in two or three dimensions of high-dimensional grids subject to rotations. This paper proposes an interface that enables the user to parametrically search for such tilings. Assembly rules are explained by which arbitrary geometry as specified by NURBS surfaces may be based on the pattern to form a non-repeating complex surface. As an example, the fabrication in concrete of a cylindrical tiling is used to demonstrate the mass production of a continuous, free-flowing structure with the aid of a minimum amount of formwork.

title	Parametric Modelling of Architectural Surfaces

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.

summary	This paper documents an ongoing research that combines recent developments in the field of Rapid Prototyping Technology for a materialisation of composite pneumatic models. The ability to create three dimensional prints with varying surface materials has the potential to assign the RP model a different role in the design process. The implementation of material performance, configured through CAD driven geometry, allows for an emergence of dynamical models that are freed from conventional representational function.

title	To Colour the Virtual World - Difficulties in Visualizing Spatial Colour Appearance in Virtual Environments
source	International Journal of Architectural Computing vol. 7 - no. 2, 289-308
summary	This paper discusses the problems of visualizing colour appearance in an interactive virtual environment (VE) from the viewpoint of practice based architectural research. The discussion is based upon the research information project Virtual Colour Laboratory (VCL), the aim of which is to visually present and demonstrate existing research results on spatial colour phenomena for educational purposes, in the shape of a software application. During the work on this project, various problems connected to the visualization of colour appearance have emerged which are discussed in relation to current research on spatial experience and visual appearance in VEs. The aim of the paper is to focus on the importance of colour appearance in digital modelling as well as to highlight the problems of visualizing colour appearance interactively. The term colour appearance is used here as a general concept for the perceived colour of a surface or object.

doi	https://doi.org/10.52842/conf.caadria.2009.597
summary	A potential way to bridge the gap between complex form generation and models for physical manifestations is to panelize NURBS surfaces with polygonal faces. This paper investigates the transition from NURBS surface to a mesh solid through a procedural modeling approach, in the process, illustrating how a discretized planar surface can be reconstructed for form generation and further exploration. The paper promotes this approach as an efficient way to modeling complex forms using an example drawn from real life architecture to demonstrate a generative process with customized restructuring.

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