summary	Today, material performance is regarded as one of the richest sources of innovation. Accordingly, architecture is shifting to practices by which the computational generation of form is directly driven by material characteristics. At the same time, there is a growing technological means for the varied composition of material, an extension of the digital chain that foregrounds a new need to engage materials at multiple scales within the design process. Recognising that the process of making materials affords perspectives not available with found materials, this paper reports the design and assembly of the fi bre reinforced composite structure Composite Territories, in which the property of bending is activated and varied so as to match solely through material means a desired form. This case study demonstrates how one might extend the geometric model so that it is able to engage and reconcile physical parameters that occur at different scales.

title	Leaving Flatland behind: Algebraic surfaces and the chimaera of pure horizontality in Architecture
doi	https://doi.org/10.52842/conf.ecaade.2012.1.433
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 1 / ISBN 978-9-4912070-2-0, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 433-441
summary	We argue that the prevalence of continuous flat floor surfaces in architecture is comprehensible but fallacious, and that this chimaera can be overcome through studying and employing the sculptural potential of algebraic surfaces which suggest spatial possibilities that enrich designers’ vocabulary enormously. We continue, deepen and extend research the basics and early results of which were presented at the last two eCAADe conferences in Istanbul and Zürich. We present and discuss a university-based experimental design and research project that demonstrates how Algebraic Surfaces can drastically amplify the so far only tentative exploration of the possibilities of non-fl at fl oor surfaces in Architecture.

summary	Behavioural Surfaces is a thesis project in Architecture discussed on December 2010 at the University of Florence. The project explores the surfacespace relationship in which a surface condition, generated from intensive datascapes derived from environmental data, is able to produce spatial differentiation and modulate structural and environmental preformance. Exploiting material self-organization in sea sponges as surfaces that deploy function and performance through curvature modulation and space defi nition, two different surface definition processes were explored to organize the system hierarchy and its performances at two different scales. At the macroscale, the global shape of the building is shaped on the base of isopotential surfaces while at a more detailed level the multi-performance skin system is defi ned upon the triply periodic minimal surfaces (TPMS).

title	A Method for Generating Regular Grid Configurations on Free-From Surfaces for Structurally Sound Geodesic Gridshells
doi	https://doi.org/10.52842/conf.ecaade.2021.2.493
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 493-502
summary	Gridshells are highly efficient, lightweight structures which can span long distances with minimal use of material (Vassallo & Malek 2017). One of the most promising and novel categories of gridshells are bending-active (elastic) systems (Lienhard & Gengnagel 2018), which are composed of flexible members (Kuijenhoven & Hoogenboom 2012). Timber elastic gridshells can be site-sprung or sequentially erected (geodesic). While a lot of research focus is on the site-sprung ones, the methods for design of sequentially-erected geodesic gridshells remained underdeveloped (Cichocka 2020). The main objective of the paper is to introduce a method of generating regular geodesic grid patterns on free-form surfaces and to examine its applicability to design structurally feasible geodesic gridshells. We adopted differential geometry methods of generating regular bidirectional geodesic grids on free-form surfaces. Then, we compared the structural performance of the regular and the irregular grids of the same density on three free-form surfaces. The proposed method successfully produces the regular geodesic grid patterns on the free-form surfaces with varying curvature-richness. Our analysis shows that gridshells with regular grid configurations perform structurally better than those with irregular patterns. We conclude that the presented method can be readily used and can expand possibilities of application of geodesic gridshells.

title	Pedagogic Approach in the Age of Parametric Architecture: Experimental method for teaching architectural design studio to 3rd year level students
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 211-226
summary	In this era, Architectural Design Practice is faced with a paradigm shift in its conventional approaches towards computational methods. In this regard, it is considered a pedagogic challenge to boost up knowledge and skills of architectural students’ towards an advanced approach of architectural design that emphasizes the potentials and complexity of computational environments and parametric tools for design problem solving. For introducing the concept of Parametric Oriented Design Methods to 3rd year level architectural students, an experimental pedagogic course was designed in the scholastic year of 2012-2013 at German Jordanian University GJU (School of Architecture and Built Environment SABE) to approach this concept. In the preparation phase, the experimental course was designed to incorporate structured instructing and training method to be consecutively performed within experimental lab environment to target predetermined learning outcomes and goals. The involved students were intentionally classified into three levels of previous involvement associated with the related software operating skills and computational design exposure. In the implementation phase, the predetermined instructing and training procedures were performed in the controlled environment according to the planned tasks and time intervals. Preceded tactics were prepared to be executed to resolve various anticipated complication. In this phase also, students’ performance and comprehension capacity were observed and recorded. In data analysis phase, the observed results were verified and correlations were recognized. In the final phase, conclusions were established and recommendations for further related pedagogic experiments were introduced.

summary	Architecture today has come to its most complex form. There are lots of criteria such as fi re safety, structure, sustainability etc… which must be controlled by the designers. To improve the performance and accessibility of buildings, governing bodies publish different codes for each of the different criteria. Buildings must comply with these codes to get a permit for construction. The checking of the buildings according the codes is done manually by code offi cials. This process is time consuming, high in cost and prone to errors. To remedy this problem by using the tools like BIM and AI, systems that can automatically check the code compliance of projects are being developed. In this paper we provide an overview of the structures and capabilities of these systems and present the automated code compliance checking system that we develop for checking building models against some parts of the Turkish Fire Codes.

doi	https://doi.org/10.52842/conf.ecaade.2012.2.573
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 2 / ISBN 978-9-4912070-3-7, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 573-581
summary	Contemporary explorations within the evolutionary computational domain have been heavily instrumental in exploring biological processes of adaptation, growth and mutation. On the other hand a plethora of designers owing to the increasing sophistication in computer aided design software are equally enthused by the formal aspects of biological organisms and are thus meticulously involved in form driven design developments. This focus on top-down appearance and surface condition based design development under the banner of organic architecture in essence contributes to the growing misuse of bio-inspired design and the inherent meaning associated with the terminology. HyperCell, a bio-inspired information design framework for real-time adaptive spatial components, is an ongoing research, at Hyperbody, TU Delft, which focuses on extrapolating bottom-up generative design and real-time interaction based adaptive spatial re-use logics by understanding processes of adaptation, multi-performance and self sustenance in natural systems. Evolutionary developmental biology is considered as a theoretical basis for this research.

summary	This paper describes the development of a design and prototype production system for novel structural use of networked small components of wood deploying elastic and plastic bending. The design process engaged with a significant number of different overlapping and interrelated design criteria and parameters, a high level of complexity, custom component geometry and the development of digital tools and procedures for real time feedback and productivity. The aims were to maximize learning in the second order cybernetic sense through empirical experience from analogue modeling, measurement and digital visual feedback and to capture new knowledge specifically regarding intrinsic material behavior applied and tested in a heterogeneous networked context. The outcome was a prototype system of design ideation, conceptualization, development and production that integrated real time material performance simulation and feedback. The outcome was amplified through carrying out the research over a series of workshops with distinct foci and participation. Two full scale demonstrators have so far been constructed and exhibited as outputs of the process.

title	Creative Design Between Representation and Simulation
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 11-12
summary	Milestone figures of architecture all have their different views on what comes first, form or function. They also vary in their definitions of creativity. Apparently, creativity is very strongly related to ideas and how they can be generated. It is also correlated with the process of thinking and developing. Creative products, whether architectural or otherwise, and whether tangible or intangible, are originated from ‘good ideas’ (Elnokaly, Elseragy and Alsaadani, 2008). On one hand, not any idea, or any good idea, can be considered creative but, on the other hand, any creative result can be traced back to a good idea that initiated it in the beginning (Goldschmit and Tatsa, 2005). Creativity in literature, music and other forms of art is immeasurable and unbounded by constraints of physical reality. Musicians, painters and sculptors do not create within tight restrictions. They create what becomes their own mind’s intellectual property, and viewers or listeners are free to interpret these creations from whichever angle they choose. However, this is not the case with architects, whose creations and creative products are always bound with different physical constraints that may be related to the building location, social and cultural values related to the context, environmental performance and energy efficiency, and many more (Elnokaly, Elseragy and Alsaadani, 2008). Remarkably, over the last three decades computers have dominated in almost all areas of design, taking over the burden of repetitive tasks so that the designers and students can focus on the act of creation. Computer aided design has been used for a long time as a tool of drafting, however in this last decade this tool of representation is being replaced by simulation in different areas such as simulation of form, function and environment. Thus, the crafting of objects is moving towards the generation of forms and integrated systems through designer-authored computational processes. The emergence and adoption of computational technologies has significantly changed design and design education beyond the replacement of drawing boards with computers or pens and paper with computer-aided design (CAD) computer-aided engineering (CAE) applications. This paper highlights the influence of the evolving transformation from Computer Aided Design (CAD) to Computational Design (CD) and how this presents a profound shift in creative design thinking and education. Computational-based design and simulation represent new tools that encourage designers and artists to continue progression of novel modes of design thinking and creativity for the 21st century designers. Today computational design calls for new ideas that will transcend conventional boundaries and support creative insights through design and into design. However, it is still believed that in architecture education one should not replace the design process and creative thinking at early stages by software tools that shape both process and final product which may become a limitation for creative designs to adapt to the decisions and metaphors chosen by the simulation tool. This paper explores the development of Computer Aided Design (CAD) to Computational Design (CD) Tools and their impact on contemporary design education and creative design.

title	Glass Cast: A Reconfigurable Tooling System for Free-Form Glass Manufacturing
doi	https://doi.org/10.52842/conf.acadia.2012.287
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 287-294
summary	Despite glass’s ubiquity in the modern built environment it is rarely applied in applications requiring complex curvature. The high temperatures and complexity of techniques utilized in forming curved glass panels are typically very expensive to employ, requiring dedicated hard-tooling which ultimately limits the formal variation that can be achieved. This combination of economic and manufacturing barriers limits both the formal possibilities and potentially the overall envelope-performance characteristics of the glazing system. This research investigates a methodology for utilizing reconfigurable tooling to form glass into doubly curved geometries, offering the potential for improved structural and environmental performance in a material that has remained largely unchanged since the advent of its industrial manufacturing. A custom built forming kiln has been developed and tested, integrated through a parametric modeling workflow to provide manufacturing constraint feedback directly into the design process. The research also investigates the post-form trimming of glass utilizing robotic abrasive waterjet cutting, allowing for the output of machine control data directly from the digital model. The potentials of the methodologies developed in this process are shown through the fabrication of a full-scale installation. By integrating material, fabrication, and design constraints into a streamlined computational methodology, the process also serves as a model for a more intuitive production workflow, expanding the understanding of glass as a material with wide-ranging possibilities for a more performative architecture.

summary	This research presents a solution for evaluation of kinetic façades system performance via experiences and lessons learnt from experiments. We bridge between architects and engineers to address limitations associated with incorporating performance criteria in the design of kinetic façades by integrating different simulation tools. The experiments focus on optimization of the daylight performance through the design and motion of kinetic façades using various integrated software. The research is developed using real time data feedback processed through various digital tools from three domains: (1) Architectural design, (2) day-lighting performance and (3) parametric design computation. From the evaluations, the paper demonstrates the analysis of kinetic motion for daylight optimization at the early design stage and suggests possible configurations for daylight performance.

summary	Buildings are the world’s largest consumer of energy, accounting for 34% of total use. In the United States residential and commercial buildings are responsible for 72% of electricity use and 40% of CO2 emissions. In order to reduce the impact of buildings on the environment and to utilize freely available environmental resources, building design must be based on site climate conditions, e.g. solar radiation and air temperature. This paper presents a web-based framework that enables the production of user-generated visualizations of weather data. The Open Graphic Evaluative Framework (Open GEF) was developed using the Graphic Evaluative Frameworks (GEF) approach to authoring design-assistant software, which is more appropriate than the now dominant ‘generalized design tool’ approach when supporting design processes that require a high level of calibration to the cyclic and acyclic shifting of environmental resources. Building on previous work that outlined the theoretical underpinnings and basic methodology of the GEF approach, technical specifi cations are presented here for the implementation of a Java driven web-based visualization platform. By enabling more nuanced and customizable views of weather data, the software offers designers an exploratory framework rather than a highly directed tool. Open GEF facilitates design processes more highly calibrated to climatic fl ows that could reduce the overall impact of buildings in the environment.

title	Zero-Waste, Flat-Packed, Tri-Chord Truss: Continued Investigations of Structural Expression in Parametric Design"
doi	https://doi.org/10.52842/conf.acadia.2012.199
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 199-208
summary	The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models. This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes. This paper will expand (greatly) upon previous research into bi-chord truss designs, developing a tri-chord truss, which is parametrically linked to its structural moment diagram. The cross section of each truss is formed based on the loading condition for each beam. This truss design has been developed through a thorough series of analytical models and tests performed digitally, to scale and in full scale. The tri-chord truss is capable of resisting rotational failures well beyond the capacity of the bi-chord designs previously developed. The results are complex, and elegant expressions of structural logics embodied in a tightly constrained functional design.

summary	In city, when temperatures run higher than those in suburban and rural areas, this generate a phenomenon called Urban Heat Island (UHI), this effect occurs, primarily because growing numbers of buildings have supplanted vegetation and trees. The main causes of the different microclimatic conditions in cities are linked among other parameters to urban geometry which influences incoming and outgoing radiations as well as surface material properties, such as color and texture. In hot climates the elevated surface temperatures of materials directly affect, not only the urban microclimate, but also thermal comfort conditions in urban open spaces. In order to evaluate the microclimate variation of urban street canyon compared to the variation of walls and ground surfaces materials, series of field simulation are used by software tool , Envi-met v3.0, in down town of Constantine, Algeria.

title	Shading With Folded Surfaces: Designing With Material, Visual and Digital Considerations

summary	This paper analyses a hybrid design approach; how physical and digital processes can inform each other in a multivalent design cycle. It describes the design of origami-inspired window shades, part of the Shaping Light project that explores how adjustable surface structures can modulate light levels and heat gain in response to the changing seasons. The screen uses sloped surfaces to diffuse light and create apertures that close when the screen is stretched and open when the screen is folded. The project complements digital methods for pattern proportioning and kinetic simulation with manual manipulation to generate 3D folding motifs and refi ne assemblies. Physical prototypes can shape digital refi nement by revealing visual and structural characteristics of materials, along with joint and production considerations. Physical models for simulating sunny and cloudy daylighting conditions provide a direct connection between spatial confi guration and visual effects. The paper concludes with guidelines for material-based digital-analog creation.

summary	The consideration about contemporary urban spaces incorporates a set of investigations linked to spatial implementation of digital technologies. This paper is about the different ways in which tangible computational interfaces have been arranged in urban environments, be they projections onto urban surfaces, interactive façades, or even architecture and interactive and/or responsive urban objects. It examines the nature of this phenomenon from perspectives presented by different authors and based on systematized information on a wide array of interfaces. It also posits some significant attributes that should be taken into account when performing a close examination of these interventions. Its aim is to contribute theoretical explorations to the study of hybrid urban spaces.

summary	The fundamental processes in living systems can be a potential resource to derive nonlinear relationships that could find application in the design of responsive surface from an architectural standpoint. This research focuses on deriving a parametric relationship from a phenomenon in cell biology to generate an architectural expression of responsive surface/ façade. It further delineates the dynamic feedback mechanism from the environment and user as control factors. Through extensive investigation of cell-to-cell connections in the mammary epithelial cells and review of evident relay of communication across the entire system of cells, we could unfold the logical parameters of the biological system. Parametric modelling indicating the causality of the surface condition, changes with the change in extracellular matrix. This gives an opportunity to manoeuvre the surface parameters, contrary to the involuntary cell environment where the behaviours are under the control of a physiological process. Architecturally, the dynamic relationship of surface in a hybridised model, explains that interactivity is not a mere one to one response to a stimulus. Evidently, this interactive process can be a sophisticated loop of feedback through different materiality and componentry that play their effects (and are played back) by “active” surfaces.

summary	Abstract Integral structural optimization and fabrication seeks the synthesis of two original approaches; that of topological optimization (TO) and robotic hotwire cutting (HWC). TO allows for the reduction of up to 70% of the volume of concrete to support a given structure. A strength of the method is that it allows to come up with structural designs that lie beyond the grasp of traditional means of design. A design space is a discretized volume, delimiting where the optimization will take place. The number of cells used to discretize the design space thus sets the resolution of the TO. While the approach of the application of TO as a constitutive design tool centers on structural aspects in the design phase, the outcome of this process are structures that cannot be realized within a conventional budget. As such the ensuing design is optimal in a narrow sense; whilst optimal structurally though, construction can be prove to be prohibitively expensive. This paper reports ongoing research efforts on the development of a cost effective methodology for the realization of TO concrete structures using HWC.

summary	From the beginning of digital revolution, structural surfaces drew significant attention as a realm that interweaves formal explorations, form-finding and structural optimization. However, after successful experimentation in the virtual domain, it became evident that some of the main challenges lay on how to translate these structural forms into architectural assemblies at the scale of buildings. The development of digital fabrication is crucial in this task, as means to overcome traditional constraints such as need for modular pieces, scaffolding and optimal assembly sequences.This research focuses on digital workflows that combine form finding with robotic fabrication, surface tessellation and panelization. In the past years, the use of digital tools to assemble identical modules into complex formations has achieved significant results for loadbearing walls. Expanding this line of research, the proposed fabrication system carries these experiments on additive fabrication into the production of structural surfaces. The assembly sequence involves a two-step fabrication: off-site panel manufacturing and on-site assembly. The main components of the system consist of two triangular ceramic pieces that provide structural resistance, refined surface finish, and formwork for thin reinforced-concrete layer. Panelization strategies reduce the requirements on-site work and formwork.The paper describes background research, concept, construction process, methodology, results and conclusions.

summary	As we stand with our feet on earth’s outermost surface we build an architecture today that is much like it was several thousand years earlier, in an attempt to extend that outer shell with one of our own making. Artificial masses are built from a refinement of this existing geologic layer into materials of stone, steel, concrete, and glass that assemble to produce new pockets of space through the buildings they create. However, the sixth century BC writer Thales of Miletus put a different perspective on this: he insisted that we live, in reality, not on the summit of a solid earth but at the bottom of an ocean of air (Holmyard 1931). And so, as architecture continues to build up the outermost layer of earth’s surface through a mimicking, embellishing, and enhancing of the materials which it comes from, it raises the question of why we have not brought a similar relationship to the materialities at the bottom of this “ocean” of air to create the spaces we call architecture. If you were looking to level a complaint with the architectural profession, stating that it has not been ambitious enough in scope would not be one. Architects have never shied away from the opportunity to design everything from the building’s shell to the teaspoon used to stir your sugar in its matching cup. But it would seem that the profession has developed a rather large blind spot in terms of what it sees as a malleable material with which to engage. Architects have made assumptions as to what is beyond our scope of action, refraining from engaging a range of material variables due to a belief that the task would be too great or simply beyond our physical control. So even though we are enveloped by them continuously, both on the exterior as well as the interior of our buildings, it must be assumed that the particles, waves, and frequencies of energy that move around us are thought by architects to be too faint and shaky to unload upon them any heavy obligations, that they are too unwieldy for us to control to create the physical boundaries of separation, security, and movement required of architecture. This has resulted in a cultivated set of blinders that essentially defines architecture as a set of mediation devices (surfaces, walls, and inert masses) for tempering the environmental context it is situated in from the individuals and activities within. The spaces we inhabit are defined by their ability to decide what gets in and what stays out (sunlight, precipitation, winds). We place our organizational demands and aesthetic opinions on the surfaces that mediate these variables rather than seeing them as available for manipulation as a building material on their own. The intention here is to recalibrate the materialities that make up that environmental context to build architecture. The starting point is a rather naive question: can we design the energy systems that course in and around us daily as an architectural material so as to take on the needs of activities, securities, and lifestyles associated with architecture? Can the variables that we would normally mediate against instead be heightened and amplified so as to become the architecture itself? That which many would incorrectly dismiss as simply “air” today—thought to be homogeneous, scale-less, and vacant due in part to the limits of our human sensory system to perceive more fully otherwise—might tomorrow be further articulated, populated, and layered so as to become a materiality that will build spatial boundaries, define activities of individuals and movement, and act as architectural space. Our environmental context consists of a diverse range of materials (particles and waves of energy, spectrum of light, sound waves, and chemical particles) that can be manipulated and formed to meet our needs. The opportunity before us today is to embrace the needs of organizational structures and aesthetics by designing the active context that surrounds us through the material energies that define it.
