title	A Parametric Description for Metamorphosis of Islamic Geometric Patterns
doi	https://doi.org/10.52842/conf.caadria.2015.593
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 593-602
summary	This paper presents a parametric approach toward studying the characteristics of the Islamic geometric patterns (IGP). The presented computational system utilizes a parametric description of the geometry to initiate the process of metamorphosis exploration and to document the generated variations. The study found that changing the parameters in the description produces new variations that have a wide range of qualitative and quantitative properties; some match exactly the properties of traditionally existed geometries.

title	A User Interface for Parametric Architectural Design Reviews
doi	https://doi.org/10.52842/conf.caadria.2015.065
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 65-74
summary	Architectural form and performance are affected by the designer's graphical representation methods. Parametric CAD systems, as design and representation tools, have become ubiquitous in architectural practice and education. Literature in the area of parametric design reviews is scarce and focused within building inspection and construction coordination domains. Additionally, platforms marketed as design review tools lack basic functionality for conducting comprehensive, parametric, and performance-based reviews. We have developed a user interface prototype where geometric and non-geometric information of a Building Information Model were translated into an interactive gaming environment. The interface allows simultaneous occupation and simulation of spatial geometry, enabling the user to engage with object parameters, as well as, performance-based, perspectival, diagrammatic, and orthographic representations for total spatial and performance comprehension.

title	The geometry of Chuck Hoberman as the basis for the development of dynamic experimental structures

summary	The cognitive-theoretical foundation referring to teach drawing as a way of thinking, as well as the construction of the environment by means of drawing using transforming geometries and the formal and para-formal computational process, creating unusual geometries through generative design processes and methodologies, can be seen as some of the main possibilities in exploring dynamic experimental structures for an Adaptive Architecture. This article presents the development of a model for articulated facades, inspired by Hoberman´s Tessellates, and his Adaptive Building Initiative (ABI) project to develop facades models that respond in real time to environmental changes. In addition, we describe an experiment based on the retractable structures, inspired by Hoberman´s work and experimentations. Solutions for responsive facades can offer more flexible architectural solutions providing better use of natural light and contributing to saving energy. Using Rhinoceros and the Grasshopper for modeling and test the responsiveness, the parametric model was created to simulate geometric panels of hexagonal grids that would open and close in reaction to translational motion effects, regulating the amount of light that reaches the building.

title	On-site Robotic Assembly of Double-curved Self-supporting Structures
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 746-753.
summary	Robotic assembly of architectural structures has been an area of research for a few decades. Yet, current methods impose a large number of constraints on the geometry of those structures. In this paper we introduce a method for robotic assembly that enables the construction of double curved self-supporting structures. Latest research challenges have focused on the assembly of sophisticated brick structures and on sensor feedback systems for handling accuracy. We propose an alternative strategy to tackle tolerance handling in complex structures that rely on geometry. The intelligence of the system lies in two main aspects: a subdivision technique that incorporates the robot’s constraints as well as the structural equilibrium of the structure during each step of assembly, in order to omit the use of scaffolding; and a match between geometric information and the robot’s movements in a robot programming environment. As a proof of concept, we fabricated a portion of a full-scale double-curved structure. The structure was assembled without scaffolding by a portable KUKA KR10 on a randomly picked site. This project aims to demonstrate an easy and simple method for robotic assembly that enables the realization of digitally generated complex geometries as concrete complex structures.

title	Analysing Populations of Design Variants Using Clustering and Archetypal Analysis
doi	https://doi.org/10.52842/conf.ecaade.2015.1.251
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 251-260
summary	In order to support exploration in the early stages of the design process, researchers have proposed the use of population-based multi-objective optimisation algorithms. This paper focuses on analysing the resulting population of design variants in order to gain insights into the relationship between architectural features and design performance. The proposed analysis method uses a combination of k-means clustering and Archetypal Analysis in order to partition the population of design variants into clusters and then to extract exemplars for each cluster. The results of the analysis are then visualised as a set of charts and as design models. A demonstration of the method is presented that explores how self-shading geometry, envelope materials, and window area affect the overall performance of a simplified building type. The demonstration shows that although it is possible to derive general knowledge linking architectural features to design performance, the process is still not straightforward. The paper ends with a discussion on how the method can be further improved.

title	Optimization in the Architectural Practice - An International Survey
doi	https://doi.org/10.52842/conf.caadria.2017.387

summary	For several years great effort has been devoted to the study of Architectural Design Optimization (ADO). However, although in the recent years ADO has attracted much attention from academia, optimization methods and tools have had a limited influence on the architectural profession. The aim of the study is to reveal users' expectations from the optimization tools and define limitations preventing wide-spread adaptation of the optimization solvers in the architectural practice. The paper presents the results of the survey "Optimization in the architectural practice" conducted between December 2015 and February 2016 on 165 architectural trainees and practising architects from 34 countries. The results show that there is a need for an interactive multi-objective optimization tool, as 78% respondents declared that a multi-objective optimization is more necessary in their practice than a single objective one and 91% of them acknowledged the need for choice of promising solutions during optimization process. Finally, it has been found that daylight, structure and geometry are three top factors which architects are interested in optimizing.

title	Mass Regimes: Geometric Actuation of Thermal Behavior
source	International Journal of Architectural Computing vol. 13 - no. 2, 169-194
summary	The Mass Regimes is a research project that investigates the effect of complex geometry on processes of passive heat distribution in thermal mass systems. In the context of systems thinking, this research intends to instrumentalize design principles that engage a wider range of design tactics for choreographing thermal gradients between buildings and their environment. Research for this project has brought about a deeper understanding of how specific geometric manipulations of surface area over the same mass (Figure 1) affect the rate of thermal transfer. Leveraging physical simulations of geometric populations, along with current computational and design tools, the project sheds light on performative trends that may enhance creative design explorations in the use of passive systems. Preliminary analysis of varied geometric populations suggest an exciting trend and the possibility for a more synthetic incorporation of morphology, one in which surface geometry can be passively utilized to generate effects with more fidelity over the pace of thermal absorption and the release of sensible heat.

title	Subdivision Surface Modeling to Foster Responsive Design Solutions in an Integrated Multi-disciplinary Team
doi	https://doi.org/10.52842/conf.ecaade.2015.1.403
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 403-413
summary	This paper documents an architectural project developed using subdivision surface modelling. Subdivision surfaces are not new, and the tools are readily available in many 3d modelling applications. Despite their age and availability and recognised benefits they are rarely applied in architectural projects furthermore there is paucity of published case studies that demonstrate these tools in action. The second contribution to the field that this paper offers is in recognising the way in which subdivision surfaces can provide a new form of collaboration. Our core team consisted of architect, artist and 3d modeller and the project was inspired by a ceramic sculpture with unusual geometry. Subdivision surface modelling enabled a unique form of design exploration, feedback and communication between people with diverse skills. This case study therefore offers both insight into applied use of subdivision modelling and further depth into the way it enables interdisciplinary collaboration.

title	Parametric BIM Workflows

source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 437-446
summary	Building Information Modelling systems enable the creation of associative parametric models that include sets of interlinked parametric objects. Graph-based modelling systems on the other hand enable the creation of parametric models with more complex iterative behaviours. Parametric BIM workflows aim to link graph-based systems to BIM systems. A key requirement of such workflows is the ability to generate associative BIM models. However, current approaches to creating such workflows are complicated by the fact that the process of cooking is only able to generate explicit geometry. An alternative approach is proposed in which the cooking process is able to generate associative models, thereby enabling more user friendly and streamlined BIM workflows to be created.

summary	The paper demonstrates a work-in-progress research on an agent-based aggregation model for architectural applications with a system of assembly based on environmental data acted as a driver for a growth mechanism. Even though the generative design and algorithms have been widely employed in the field of art and architecture, such applications tend to stay in morphological explorations. This paper examines an aggregation model based on Diffusion Limited Aggregation system incorporating solar environment analysis for global perspective of aggregation, the geometry research for lattice systems, and morphological principles of unit module in agent scale. The later part of this research paper demonstrates the potential of a design process through the “Constructed Cloud” case study, including site-specific applications and the implementation of the systematized rule set.

title	An Inductive Construction of Rigid Panel-Hinge Graphs and Their Applications to Form Design
source	International Journal of Architectural Computing vol. 13 - no. 1, 45–64
summary	A panel-hinge framework is a structure composed of rigid panels connected by hinges. It was recently proved that at a generic position, the rigidity of panel-hinge frameworks can be predicted by examining a certain combinatorial property of the underlying graph. In this study, we apply such combinatorial characteristics to create design forms. When considering the application of design forms, we must also take into account non-generic cases. In this paper we develop two new approaches; the first one that the method inductively generates non-generic rigid panel-hinge frameworks consisting of orthogonal panels and the second one that inductively generates non-generic rigid panel-hinge frameworks based on fractal geometry coupled with space-filling convex polyhedron as a construction unit. We will give examples of forms created by the proposed method in order to demonstrate the applicability of the proposed methods to design forms.

summary	Architects are used to work with models since the early beginnings of Renaissance. These models were made to conceive spatial objects before they become realized. Nowadays space seems to be outdated: There are information topologies, virtuality, and globalization. Our models are logistical rather than spatial and they become increasingly complicated. They put an emphasis on energy- or cost-efficiency rather than the vividness of a localized place. But as Architects we are supposed to be ‚masters of space’. And somehow it feels like we have lost our domain and degraded ourselves to attaching nice skins on increasingly optimized concrete- or steel-skeletons. In this sense it might be necessary to reconsider our mastership upon the articulation of space. One way to achieve this might be that computation could do more than just deliver increasingly intriguing geometries, instead it might offer us a look at the spaces conceivable but not yet imaginable: computed as information topologies and then rendered back into the geometrical framework of physical space. New media have entered our perception to a degree never imagined by future sciences of the past. So the question arises if space-time can still be considered as a single layer in actuality. As individualization takes command, being special becomes normality. In a quantized society, where many cultures coexist at the same places simultaneously, a new model to space must deal with the superposition of territories.

title	A Collaborative Approach to Digital Fabrication:A Case Study for the Design and Production of Concrete ‘Pop-up’ Structures
source	International Journal of Architectural Computing vol. 13 - no. 2, 195-216
summary	The research presented in this paper utilizes industrial robotic arms and new material technologies to model and explore a prototypical workflow for on-site robotic collaboration based on feedback loops. This workflow will ultimately allow for the construction of customized, free-form, on-site concrete structures without the need for complex formwork. The paper starts with an explanation of the relevance of collaborative robotics through history in the industry and in architecture. An argument is put forward for the need to move towards the development of collaborative processes based on feedback loops amongst the designer, the robot and the material, where they all inform each other continuously. This kind of process, with different degrees of autonomy and agency for each actor, is necessary for on-site deployment of robots. A test scenario is described using an innovative material named concrete canvas that exhibits hybrid soft fabric and rigid thin-shell tectonics. This research project illustrates the benefits of integrating information-embedded materials, masscustomization and feedback loops. Geometry scanning, parametric perforation pattern control, computational analysis and simulation, and robotic fabrication were integrated within a digital fabrication deployment scenario. The paper concludes with a detailed report of research findings and an outline for future work.

title	Adaptive Pneumatic Shell Structures - Feedback-driven robotic stiffening of inflated extensible membranes and further rigidification for architectural applications
doi	https://doi.org/10.52842/conf.ecaade.2016.1.549
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 1, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 549-558
summary	The paper presents the development of a design framework that aims to reduce the complexity of designing and fabricating free-form inflatables structures, which often results in the generation of very complex geometries. In previous research the form-finding potential of actuated and constrained inflatable membranes has already been investigated however without a focus on fabrication (Otto 1979). Consequently, in established design-to-fabrication approaches, complex geometry is typically post-rationalized into smaller parts and are finally fabricated through methods, which need to take into account cutting pattern strategies and material constraints. The design framework developed and presented in this paper aims to transform a complex design process (that always requires further post-rationalization) into a more integrated one that simultaneously unfolds in a physical and digital environment - hence the term cyber-physical (Menges 2015). At a full scale, a flexible material (extensible membrane, e.g. latex) is actuated through inflation and modulated through additive stiffening processes, before being completely rigidified with glass fibers and working as a thin-shell under compression.

title	Exact Face-Offsetting for Polygonal Meshes
doi	https://doi.org/10.52842/conf.acadia.2015.203
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 203-210
summary	Planar-faced mesh surfaces such as triangular meshes are frequently used in an architectural setting. Face-offsetting operations generate a new mesh whose face planes are parallel and at a fixed distance from the face planes of the original surface. Face-offsetting is desirable to give thickness or layers to architectural elements. Yet, this operation does not generically preserve the combinatorial structure of the offset mesh. Current approaches to this problem are to restrict the geometry of the original mesh to ensure that the combinatorial structure of the underlying mesh is preserved. We present a general algorithm for face-offsetting polygonal meshes that places no restriction on the original geometry. The algorithm uses graph duality to describe the range of possible combinatorial outcomes at each vertex of the mesh. This approach allows the designer to specify independent offset distances for each face plane. The algorithm also produces a "perpendicular" structure joining the original mesh with the offset mesh, that consists of only planar elements (i.e. beams).

summary	In the aspiration to design the built environment, architects and designers are continuously trying to create spaces that positively affect users. Both aspects of rational and emotional combined simultaneously with technological advancement are essential to implement in a comprehensive architectural design process. While our ability to create complex architectural forms through computation is in the state of a continuous improvement, our knowledge about their emotional effects over users remain ambiguous. Recent developments in simulation of virtual spaces, along with advancement in neuroscience may enable us to conduct an empirical research on the way we perceive space and the way space affects us emotionally. This paper presents initial results from an ongoing research that examines the connection between human feelings and architectural space. We discuss the first stage of the research in which as we examine the emotional reaction of designers and non-designers to various spatial geometries in an immersive 3D virtual environment inside a visualization laboratory. We then present the methodology for the second stage of the research, in which we repeat the experiment while using Electroencephalography (EEG) device together with a wireless eye tracker and emotional engagement measurements (EEM) system.

summary	This study focuses on developing three-dimensional solar panels, as an alternative to traditional flat Photovoltaic (PV) surfaces in Building Integrated Photovoltaic (BIPV). We propose to increase the energy efficiency of buildings by using the entire envelope for energy production as well as by increasing the efficiency of solar energy output in orientations which were traditionally considered as non-ideal. The panels are constructed from Polycarbonate with integrated flexible photovoltaic film, solar paint or dye. The methodology included digital algorithm-based tools for achieving optimized variable three-dimensional surfaces according to local orientation and location, computational climatic simulations and comparative field tests. In addition, the structural, mechanical and thermal properties of the integration between flexible PV sheets and hard plastic curved panels were studied. Interim results demonstrate a potential improvement of 50-80% in energy production per building unit resulting from geometric variations per-se. The dependence of energy production by surface geometry was revealed and an optimized method for solar material distribution on the surface was proposed. A parametric digital tool for automatic generation of optimized three-dimensional panels was developed together with a database and material models of the optimized panels system.

summary	In the field of architectural design, Diffusion-limited aggregation (DLA) has been widely adopted in the study of macroscopic urban terrains and structures. If we consider individual habitats as having the same gene as our city, the intrinsic nature of DLA provides interesting insights in emulating local interactions that take place at microscopic level. This paper takes the dynamics of the DLA to the smallest unit of designable space. Whilst Phase I focuses mainly on Euclidean constraints, Phase II looks at how such generative space can add complexity to an open office plan by allowing different physical attributes to interact with one another based on the company’s organizational chart.

summary	Digital fabrication technologies are changing rapidly the way we design, as any other tool would affect the way we produce space. Multi layered 3D printing is already allowing architects, designers and engineers to experiment with new design processes and new ways of production. At the same time, little research has being done in the way gradient transparency (through multiple layered surfaces) can affect the design process through computation; a field that deserves further investigation. The focus of this paper is to explore bio-inspired material finding design processes while combining biology, architecture and material science. We explore performance driven design possibilities through a study of marine animals -and specifically cephalopods- where opacity between skin layers is controlled through color pigments - while black pigments are called melanophores - which is often used as a type of camouflage. We propose a computation model that follows the logic of gradient transparency through pigments to fit complex “host surfaces”. We define a “host” surface as a basic geometry on which the pigments are computed. This study provides the methodology for the design of biomimetic surfaces with gradient transparency, using controlled and computated sub geometries analogous to the melanophores pigments. We finally propose Pigment Skin, a computational design model as an example to materialize this study.
