title Functionally Graded Architectural Detailing using Multi-Material Additive Manufacturing
source P. Janssen, P. Loh, A. Raonic, M. A. Schnabel (eds.), Protocols, Flows, and Glitches - Proceedings of the 22nd CAADRIA Conference, Xi'an Jiaotong-Liverpool University, Suzhou, China, 5-8 April 2017, pp. 427-436

summary The paper presents a future architectural detailing strategy enabled by the design of functionally graded materials (FGM). In specific, our proposal suggests the possibility of removing mechanical fasteners and adhesives from joint details. This is achieved by combining the principles of interlocking joineries found in traditional timber structures and current Multi-Material Additive Manufacturing (MMAM) technology to materialise FGMs. FGM belongs to a class of advanced materials characterised by variation in properties as the dimension varies by combining two or more materials at a microscopic scale (Mahamood et al. 2012). FGM is ubiquitous in nature and, when properly designed, can exhibit superior performance characteristics compared to objects comprised of homogeneous material properties. With the aim of developing interlocking details with improved performance, reliability, and design flexibility, we focus on controlling material stiffness, joint fitting, and geometry through the design of the microscopic material layout. A case study design will be presented to illustrate the process.

title The Meaning of BIM

summary The paper is a position paper, not a report about a research project. It concerns the paradigm-shift that is taking place in the CAAD software and its implications for the business of architecture and more importantly, for the education of future members of the profession. Twenty years ago the use of CAAD software as a replacement for hand drafting was starting. Since then the transformation is complete: hardly a final project in the universities is drawn by hand. Currently, we are witnessing a second paradigm shift and its name is BIM. The meaning of BIM is rooted in two significant differences to current CAAD software and this will have implications for teaching and practicing architecture. The first difference is the way the software structures information in the CAAD file. The standard way to save CAAD information was to organise simple geometric objects according to membership in groups and to sort them according to a layer-metaphor, which primarily controlled the visibility of the geometric elements. Three-dimensional modelling is/was nothing more than the same structure with a more complex geometry. BIM software changes this structure by storing classes of geometries and then to store the specific values of individual geometries according to factors that can be determined by external or internal logical factors. The implication for architects is that we have the chance to be the people in control of the building information model, so long as we invest the time and energy to fully understand what is happening to the building information during the planning process. If we ignore this, the real danger exists that the last control of the building’s final configuration will be usurped. As educators we are currently teaching students that will be leaving the schools in 2012 and beyond. By then, the paradigm-shift will be in full motion and so it behoves us to consider which skill sets we want the next generation of architects to possess. This means not just teaching students about how to use particular BIM software or how to program a certain parametric/genetic algorithm in a form-finding process. We need to teach our students to take the leadership in building information management and that means understanding and controlling how the building information flows, how the methodologies that are used by the consulting engineers affect our building models, and knowing what kind of logical inconsistencies (internal or external) can threaten the design intention.

summary This paper presents a concept of origami as a form-generator for a structural system that allows deployability for structures with large spans. The presented approach studies the embedded kinetic possibilities of folded structures and focuses on a parametric modelling process that allows evaluating the structural performance of different types of the same origami family in order to optimize the geometry for a given scenario. The workfl ow between scripting based form generation – within Rhinoceros and Excel – and LS-DYNA is presented in detail. In addition to that the question of scalability from a thin microstructure to a thickened roof structure is discussed in the context of an architectural project.

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 Our team is currently engaged in the peer review of a large steel stadium dome roof. The roof has a diameter of approximately 300m and rises to over 70m in elevation. In addition to its size, the roof also contains a moveable component which can be deployed during inclement weather. The roof structure comprises of approximately 32,000 beams with 10,000 nodes. This paper overviews our efforts in scaling digital design techniques with regards to automation and parametric geometry to expedite the verification of structural members and geometrically complicated connection nodes. The paper will discuss two realms where automation was deployed. The first realm is the verification of Type 1 node connections where less than eight members intersect at a single work point and is relatively geometrically simple. Type 1 nodes were checked against published code requirements. Type 2 connections consisted of nodes where more than eight members intersected or bracing angles did not meet code guidelines. Type 2 nodes were verified using the finite element method and large scale automation of node geometry creation to structural analysis post processing was employed.

summary The following pages show a selection of studio projects which explore the opportunistic collaborative process between commercial fabricators, material sponsorships, and the institution. The articles speaks about the intersection of design experimentation and significance of fabrication within the contained process of [design | optimisation | fabrication]. Within this process the article intersects between practice, commercialisation, and design-research, into the development arena of architectural academic outcomes. The demonstrating fact within much of the research and development also touches upon intricate details of modularity, and designing with optimisation in mind for the purpose (and ease) of fabrication, prototyping, and ‘real-life’ production. While the focus of the academic studios deliberates and uses parametric design systems through digital and analogue modelling to contribute to a full scale designed installation, and actively working with a commercial fabricator and material sponsor (Luxx Newhouse & LG Hausys HI-MACS). The aim of the courses were to acquaint students with theoretical and practical conditions needed for the creating of experimental relational modularity between geometry, scale, and materials as well as the ability to negotiate between quick intuitive studies and definitive quantifiable decisions.

title Conventions of Control: A Catalog of Gestures for Remotely Interacting With Dynamic Architectural Space
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. 429-438

summary The intent of this project is to create a catalogue of gestures for remotely controlling dynamic architectural space. This research takes an essential first step towards facilitating the field of architecture in playing a role in developing an agenda for control. The process of the project includes a sequence carried out in four stages: 1) Research of gestural control 2) Creating an initial catalogue of spatial architectural gestures 3) Real-world testing and evaluation and 4) Refining the spatial architectural gestures. In creating a vocabulary for controlling dynamic architectural environments, the research builds upon the current state-of-the-art of gestural control which exists in integrated touch- and gesture-based languages of mobile and media interfaces. The next step was to outline architecturally specific dynamic situational activities as a means to explicitly understand the potential to build gestural control into systems that make up architectural space. A proposed vocabulary was then built upon the cross-referenced validity of existing intuitive gestural languages as applied to architectural situations. The proposed gestural vocabulary was then tested against user-generated gestures in the following areas: frequency of "invention", learnability, memorability, performability, efficiency, and opportunity for error. The means of testing was carried out through a test-cell environment with numerous kinetic architectural elements and a Microsoft Kinect Sensor to track gestures of the test subjects. We conclude that the manipulation of physical building components and physical space itself is more suited to gestural physical manipulation by its users instead of control via device, speech, cognition, or other. In the future it will be possible, if not commonplace to embed architecture with interfaces to allow users to interact with their environments and we believe that gestural language is the most powerful means control through enabling real physical interactions.

summary The challenge of developing adaptive, responsive low-energy architecture requires new knowledge about the complex and dynamic interaction between envelope architecture and optimisation between competing environmental performance metrics. Advances in modelling the geometry of building envelopes and control technologies for adaptive buildings now permit the sophisticated evaluation of alternative envelope configurations for a set of performance criteria. This paper reports on a study of the parametric control of a building envelope based on moveable façade components, acting as a shading device to reduce thermal gain within the building. This is investigated using a novel pentagonal tiling strategy considering the component design, tessellation and control methods.

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.

title Toward a performance-oriented architecture: An integrated design approach to a real time responsive structure

summary This paper started from the study of “performance-oriented architecture” for the purpose of developing a real time responsive prototype that can enclose large expansive interior space. Questions regarding the relationship between the structural arrangement of systems and the natural environment initiated an investigation in Phyllotaxis. It has been found in plant systems for the optimisation of photosynthesis with harvesting maximum amounts of solar energy. In the design of a real time responsive prototype, an algorithmic approach is introduced with the mathematical interpretation of Phyllotaxis and its translation into the global geometry of the prototype. Also, the usage of a Voronoi diagram is parametrically configured to form the local geometry of the prototype. The interactive mechanism of the prototype was achieved with an assorted computational application. Furthermore, with the demonstration of the aforementioned prototype in both digital and physical environments, its implementation process is explained.

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.

summary Digital architecture is at an exciting but challenging stage of its development. Past decades have witnessed important developments in computer-generated architectural representations. These tools have complemented and, in some cases, superseded the traditional forms of design and communication. In parallel with progress in computer graphics, advances in computer generated architectural representations have evolved to deliver photorealistic computer generated imagery. However, there is evidence to suggest that these advances have not significantly enhanced collaborative practices. It was acknowledged that to address the fragmentation of the industry, a fundamental change to deliver digital architecture was needed. Dealing with the requirements for an improved co-ordination and co-operation between designers and other stakeholders to encourage more integration has therefore become a central issue in the last decade. It was also recognised that significantly more intelligence needs to be brought to bear on the decision-making process if the targets set by the sustainability agenda are to be met. The quest for an improved quality of information and decision making has shifted the emphasis from computer-generated imagery to integrated building information. The recent emergence of building information modelling (BIM) constitutes one of the most exciting developments in the field. It was suggested that BIM will deliver considerable sophistication and judgment in decision-making. This keynote speech seeks to examine the implications of the transition of digital architecture from simulation and visualisation to information modelling. It aims to shed light on the methodological and technological challenges facing practitioners, researchers, and software developers, as a result of the early adoption of BIM.

title Generation and Integration of an Aerodynamic Performance Data Base Within the Concept Design Phase of Tall Buildings
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. 87-96

summary Despite the fact that tall buildings are the most wind affected architectural typology, testing for aerodynamic performance is conducted during the later design phases well after the overall geometry has been developed. In this context, aerodynamic performance studies are limited to evaluating an existing design rather than a systematic performance study of design options driving form generation. Beyond constrains of time and cost of wind tunnel testing, which is still more reliable than Computational Fluid Dynamics (CFD) simulations for wind conditions around buildings, aerodynamic performance criteria lack an immediate interface with parametric design tools. This study details a framework for empirical data collection through wind tunnel testing of building mechatronic models and the expansion of the collected dataset by determining a mathematical interpolating model using an Artificial Neural Network (ANN) algorithm developing an Aerodynamic Performance Data Base (APDB). Frederick Keisler called the interacting of forces CO-REALITY, which he defined as The Science of Relationships. In the same article Keisler proclaims that the Form Follows Function is an outmoded understanding that design must demonstrate continuous variability in response to interactions of competing forces. This topographic space is both constant and fleeting where form is developed through the broadcasting of conflict and divergence as a system seeks balance and where one state of matter is passing by another; a decidedly fluid system. However, in spite of the fact that most of our environment consists of fluids or fluid reactions, instantaneous and geologic, natural and engineered, we have restricted ourselves to approaching the design of buildings and their interactions with the environment through solids, their properties and geometry; flow is considered well after the concept design stage and as validation of form. The research described herein explores alternative relations between the object and the flows around it as an iterative process, moving away from the traditional approach of Form Follows Function to Form Follows Flow.

title Cellular Robotic Architecture
source International Journal of Architectural Computing vol. 10 - no. 3, 319-339
summary An emerging need for interactive architecture is currently making buildings mutable, flexible in use, and adaptable to changes in climate by introducing robotic systems. However, the feasibility of the seamless integration of building construction details and kinetic robotics has become a critical issue for developing robotic architecture. The objective of this work is to develop a robotic architecture with an emphasis on the integration of cellular robotics with a distributed kinetic building surface. The kinetic building surface integrates an actuating system, a localization and remote control system, which become part of the kinetic building system. This paper presents a systematic framework by reviewing theories and related work of robotic architecture and automated control. An architectural design scheme is proposed to simulate a scenario of application in a physical space. The functionality of the electrical and control system and the integration of the effects of actual construction were examined by a prototype of a kinetic surface. Our prototype presents a feasible construction method, and a prominent energy-saving effect. The potential strength and restrictions of the cellular robotic approach to architectural applications are discussed. The applicability of the prototype system and issues about controlling the behavior of spatial robots are demonstrated in this paper.

summary The intention of this research is to develop a design system for geometrically complex passive houses. Research focuses especially on the link-up of the CAAD (Computer-aided architectural design) and the CAM process (Computer-aided manufacturing) and deals only with timber structures. The aim of the project is to develop a system that would automate a creation of the computer model of the geometrically complex timber structures and link it to fabrication process. It should be possible to use the system for houses of the size of a family house up to an apartment house. The advantages of the system ought to be the fabrication preciseness, economical availability, high speed of construction, eco-friendliness and above all absence of geometrical constraints.

summary Creating architectural form requires much more than a moment of inspiration; it requires understanding form in its whole structure. In teaching architecture aiming for the architectural design a group of strategies is needed to prepare students for the creative process. In this process it begins with issues such as the geometry allows the students redeem their prior knowledge. This paper compares, in two different contexts of the initial stages of architectural teaching process, the results of activities of digital graphic representation of architectural structures. These activities are supported by the analysis of shape grammar in promoting the learning process in a comprehensive manner such as suggested by Wertheimer.

The main objective of this effort was to convert the linearity of time during the hearing of a musical piece into a continuous pathway and an architectural stroll on a given site. To this end, the musical piece is used as a source of data, which, with the use of developed algorithms, are converted into spatial data. A purely instrumental piece, “Air,” from the suite for strings in D major by Bach, provided the source data used in the design of Park D, a section of a Cultural Park in the suburbs of Athens, Greece. The developed algorithms presented in the paper include: a) an algorithm for generating the shape of the path and the space defi ning elements along the path, and b) an algorithm that generates the geometry of four harmonographic structures.

title Adaptive Distributed Robotics for Environmental Performance, Occupant Comfort and Architectural Expression
source International Journal of Architectural Computing vol. 10 - no. 3, 341-359
summary The integration of adaptive distributed robotics in architectural design has the potential to improve building energy performance while simultaneously increasing occupant comfort. In addition, conceiving buildings as dynamic systems with the ability to adapt to the changing environments in which they exist, opens new aesthetic possibilities for designers. As the façade of a building is a common place to address issues of energy performance and occupant comfort, this paper presents a first prototype of an adaptive solar envelope (ASE). Its functions are to provide distributed shading, solar power generation through integrated photovoltaics, and daylight distribution. We describe the interdisciplinary design process, and illustrate the architectural possibilities that arise from a distributed systems approach. The ASE is expanded to work in parallel with an adaptive artificial lighting element. Rather than being preprogrammed, the systems adapt their behavior through interaction with the environment and building occupants. This adaptation to the user's wishes is demonstrated successfully for the artificial light controller. We argue that with presently available technology and an increased exposure of architecture students and practitioners to adaptive design techniques, adaptive architectures will soon become a regular element of the built environment.

title Using the human body as an interactive interface for navigation in VR models
source Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 79–88

summary The use of Virtual Reality (VR) and interactive real-time rendering in urban planning and building design are becoming more and more common. However, the integration of VR in the urban planning process suffers from the complicated interaction handling of the virtual environment. In particular, people unfamiliar to gaming environments and computers are less prone to interact with a VR visualisation using keyboard and mouse as controlling devices. This paper addresses this issue by presenting an implementation of the XBOX 360 Kinect sensor system, which uses the human body to interact with the virtual environment. This type of interaction interface enables a more natural and user-friendly way of interacting with the virtual environment. The validation of the system shows that respondents perceived the interface as non-demanding and easy to use. The implemented interface to switch between different architecture proposals gave a better understanding and spatial reasoning for the respondent. The study also shows that males perceived the system as more demanding than females. The users also associated and compared their body with virtual environment, which could indicate that they used their body during spatial reasoning. This type of spatial reasoning has been agued to enhance the spatial-perception.

title Sewing timber panels: An innovative digitally supported joint system for self-supported timber plate structures
source Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 213–222
doi https://doi.org/10.52842/conf.caadria.2012.213
summary This paper focuses on the joint system of flat panels as parts of a freeform building. This topic is a key area of the ongoing founded research project, in which we investigate nonstandard shapes, realized with standard building materials, namely cross-laminated timber (CLT). We use different discretization algorithms to overlay arbitrary freeform surfaces with ornaments consisting of polygonal flat panels. We investigate a series of ornaments and their discretization results on different surfaces. In this paper, we will present and discuss a new timber-to-timber joint system that we developed exclusively for this project. We discuss the results of the load tests that we performed recently and we take a look at the construction dependent requirements of the joint system concerning the tolerances and the geometry and also, how these constraints inform the digital process. As we will discuss throughout the paper, in earlier publications we described the form finding process and the geometrical guidelines for the discretization of a desired freeform building using ornamental flat patterns. This paper moves one step further as the digital becomes physical and it is closely related to building construction and the computational design outset.
