title	Using Tensegrity and Folding to Generate Soft Responsive Architectural Skins
doi	https://doi.org/10.52842/conf.ecaade.2016.1.529

summary	This paper describes the process of designing a prototype for a soft responsive system for a kinetic building facade. The prototype uses lightweight materials and mechanisms to generate a building facade skin that is both soft (less dependent on hard mechanical systems) and responsive (dynamically and simultaneously adapting to spatial and environmental conditions). By combining concepts stemming from both tensegrity structures and folding mechanisms, we develop a prototype that changes dynamically to produce varying facade patterns and perforations based on sensor-network data and feedback. We use radiation sensors and shape memory alloys to control the prototype mechanism and allow for the required parametric adaptation. Based on the data from the radiation sensors, the lengths of the shape memory alloys are altered using electric wires and are parametrically linked to the input data. The transformation in the resulting overall surface is directly linked to the desired levels of daylighting and solar exposure. We conclude with directions for future research, including full scale testing, advanced simulation, and multi-objective optimization.

title	Development of Kinetic Facade Units with BIM-Based Active Control System for the Adaptive Building Energy Performance Service
doi	https://doi.org/10.52842/conf.caadria.2016.517

summary	This paper proposes a novel concept and practice to engage the BIM model as a control system of building energy performance service. This issue can be divided into two sub-issues including the development of more eco-friendly fac?ade which can interact with its local environment, and the related active control system which can process the environmental parameters for eco-friendly actions. This research designs the Parametric Adaptive Skin System (PASS) to en- gage the adaption of natural sunlight use for higher building perfor- mance. PASS consists of kinetic fac?ade components dominated by the BIM-based parametric engine called Dynamo. The PASS prototype demonstrates that the workflows is successful in using a real light sen- sor plus simulated solar terms to drive the interaction of virtual Revit model and physical PASS model.

title	A smart bracelet: An alternative interfaces between performer and audience
doi	https://doi.org/10.52842/conf.caadria.2016.311
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 311-319
summary	Performing arts has been one of the main recreational activ- ities in people’s life. However, most performing arts, performers usu- ally used one direction to express performing contents to the audienc- es. It means there is no real-time communication channel between the performers and audience in most performance. Hence the challenge of this research is how to provide a better relationship between the per- formers and audience without disturbing the show? This research we implemented a bio-sensor embedded smart bracelet which is able to transmit the feelings from user’s to stage by monitoring biological signal (ex: Galvanic skin response) immediately. When most audienc- es have the same physiological reaction to a certain level, the stage scene would be changed the colour and pattern to let performers know how the audiences’ feeling now. Performers would enhance self- confidence and then incorporate the audiences’ feedback to create their future performance. By applying this interactive interface to per- forming arts, we explored a new vision of performance that can not only enhance the diversity of performance but also provide a comfort- able communication channel between performers and audiences, and improve the confidence of the performers.

title	The Grammar of Crystallographic Expression
doi	https://doi.org/10.52842/conf.acadia.2016.236
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 236-243
summary	This paper stems from a research collaboration which brings together two disciplines at different ends of the scale spectrum: crystallography and architecture. The science of crystallography demonstrates that the properties of crystalline materials are a function of atomic/molecular interactions and arrangements at the atomic level—i.e., functions of the form and structure of the material. Some of these nano-geometries are frameworks with special characteristics, such as uni-directional porosity, multi-directional porosity, and varied combinations of flexibility and strength. This paper posits that the symmetry operations implicit in these materials can be regarded as a spatial grammar in the design of objects, spaces, and environments. The aim is to allow designers and architects to access the wealth of structural information that is now accumulated in crystallographic databases as well as the spatial symmetry logics utilized in crystallography to describe molecular arrangements. To enable this process, a bespoke software application has been developed as a tool-path to allow for interoperability between crystallographic datasets and CAD-based modelling systems. The application embeds the descriptive logic and generative principles of crystallographic symmetry. Using this software, the project, inter alia, produces results related to a class of geometrical surfaces called Triply Periodic Minimal (TPM) surfaces. In addition to digital iterations, a physical prototype of one such surface called the gyroid was constructed to test potential applications in design. The paper describes the development of these results and the conclusions derived from the first stage of user testing.

summary	Building Performance simulation is escalating towards design optimization worldwide utilizing computational and advanced tools. Egypt has its plan and agenda to adopt new technologies to mitigate energy consumption through various sectors. Energy consumption includes electricity, crude oil, it encompasses renewable and non-renewable energy consumption. Egypt Electricity (EE) consumption by sector percentages is residential (47%), industrial (25%) and commercial (12%), with the remainder used by government, agriculture, public lighting and public utilities (4%). Electricity building consumption has many divisions includes HVAC systems, lighting, Computers and Electronics and others. Lighting share of electricity consumption can vary from 11 to 15 percent in mixed buildings as in our case study which definitely less that the amount used for HVAC loads. This research aims at utilizing shape morphogenesis on facades using geometric shape grammar to enhance daylighting while blocking longwave radiations causing heat stress. Mixed-use building operates in daytime more than night which emphasizes the objective of this study. Results evaluation is referenced to LEED v4.1 and ASHRAE 90.1-2016 window-to-wall ratio calibration and massive wall description. Geometric morphogenesis relies on three main parameters; Pattern (Geometry Shape Grammar: R1, R2, and R3), a reference surface to map from, and a target surface to map to which is the south-western façade of the case study. Enhancing Geo-morph rule is to guarantee flexibility due to the rotation of sun path annually with different azimuth and altitude angles and follow LEED V4.1 enhancements of opaque wall percent for building envelope.

title	Generating two-dimensional schematic diagrams of mechanical, electrical, and plumbing systems from three-dimensional building information models
source	International Journal of Architectural Computing vol. 14 - no. 3, 219-232
summary	In this article, we propose a method of generating two-dimensional schematic diagrams from three-dimensional models of mechanical, electrical, and plumbing systems on computer-aided design software to represent this information in a more traditional, user-friendly format. It can be difficult to grasp the relationships between various mechanical, electrical, and plumbing elements in building information models because they are represented in a visually complex, three-dimensional manner. On the other hand, the relationships between building elements can be easily understood when using traditional schematic diagrams. First, the network of mechanical, electrical, and plumbing systems and a section view are extracted separately from three-dimensional models. Next, these extracted files are displayed as schematic diagrams on computer-aided design software. The expressions of traditional drawings were referenced to generate new diagrams. After schematic diagrams were created, they were evaluated by staff members in the facilities department of a university in Japan.

title	Adaptive Decorative Building Skin
doi	https://doi.org/10.52842/conf.caadria.2016.425
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 425-434
summary	Traditional decorative ornaments were commonly used on the building skin of traditional architecture. Nowadays in urban areas, those ornaments become less popular for they are considered old- fashioned and due to the lack of technical function that matches with the modern building designs. Based on those issue, this paper pro- posed a type of building skin that aimed to revive a new expression of traditional decorative elements by applying digital design tools and technology as well as having an adaptive function. Traditional decora- tive ornaments merged in an adaptive skin that used traditional pat- terns as a controller of the effect of environmental changes in a build- ing could provide a new expression of the use of traditional ornaments on a building in accordance with the times. Most of the adaptive building skin used kinetic techniques in order to make its formation and pattern transformable. This paper proposed a parametric-cam mechanism to transform the pattern of traditional ornament using pre- programmed analysis data of environmental changes to parametrically drive the number of rotation phase and length of nose that generated the shape of the cams. In conclusion, this paper has developed a proto- typical tool that facilitates the new approach to kinetic decorative or- naments on building skin.

title	Robotic Forming: Rapidly Generating 3D Forms and Structures through Incremental Forming
doi	https://doi.org/10.52842/conf.caadria.2016.539
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 539-548
summary	The past years have seen significant developments in the area of robotic design interfaces. Building upon visual programming environments, these interfaces now allow the creative industry to de- fine even complex fabrication processes in an easy, accessible way, while providing instant, production-immanent feedback. However, while these software tools greatly speed up the programming of robot- ic arms, many processes are still inherently slow: Subtractive process- es need to remove a large amount of material with comparably small tools, while additive processes are limited by the speed of the extruder and the properties of the extruded material. In this research we present a new method for incrementally shaping transparent polymer materi- als with a robotic arm, without requiring heat or dies for deep- drawing, thus allowing us to rapidly fabricate individual panels within a minimum of time.

title	In Search of Design Parameters for Well-Being and Creativity in Knowledge Work Environments

summary	Contemporary knowledge working environments are rapidly evolving alongside the digital and virtual technologies used for knowledge work. Contemporary offices range from cellular offices with assigned desks to activity-based offices with shared-desk policies and location independent blended working. Furthermore, advanced technologies, such as intelligent and adaptive lighting, are being implemented in our everyday surroundings, including working environments. The changes require adaptation from both knowledge workers and architectural elements of the environments. We propose that knowledge work environments should be explored from user-centric point of view and we aim to elucidate how the physical design of the workplace enhances well-being, creativity and innovation of their users. The various parameters of knowledge work environments should be specified through architectural design process but also through ethnographic methods, which enable us to retrieve the parameters of knowledge work environments users deem important. Using both spatial design and functional design approach we will challenge the multidimensional problem field of designing collaborative knowledge work environments.

title	Highly Informed Robotic 3D Printed Polygon Mesh: A Nobel Strategy of 3D Spatial Printing
doi	https://doi.org/10.52842/conf.acadia.2016.298
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 298-307
summary	Though robotic 3D printing technology is currently undergoing rapid development, most of the research and experiments are still based on a bottom up layering process. This paper addresses long term research into a robotic 3D printed polygon mesh whose struts are directly built up and joined together as rapidly generated physical wireframes. This paper presents a novel “multi-threaded” robotic extruder, as well as a technical strategy to create a “printable” polygon mesh that is collision-free during robotic operation. Compared to standard 3D printing, architectural applications demand much larger dimensions at human scale, geometrically lower resolution and faster production speed. Taking these features into consideration, 3D printed frameworks have huge potential in the building industry by combining robot arm technology together with FDM 3D printing technology. Currently, this methodology of rapid prototyping could potentially be applied on pre-fabricated building components, especially ones with uniform parabolic features. Owing to the mechanical features of the robot arm, the most crucial challenge of this research is the consistency of non-stop automated control. Here, an algorithm is employed not only to predict and solve problems, but also to optimize for a highly efficient construction process in coordination of the robotic 3D printing system. Since every stroke of the wireframe contains many parameters and calculations in order to reflect its native organization and structure, this robotic 3D printing process requires processing an intensive amount of data in the back stage.

summary	Environmentally sound and high-performance buildings are contributing towards a sustainable future. With increased density of contemporary urban space and the urgent desire to promote building performance, a better understanding of wind behaviour will positively influence future design explorations. In the traditional sequential ar- chitectural practice, there is a gap between design and performance simulation. This paper presents an experimental and systematic study of the performance-oriented design tools, strategies and workflows utilized in the concept prototyping of a high-rise building. It describes a new approach to incorporate wind tunnel testing, computational flu- id dynamics simulation as well as parametric software, sensors and open-source electronics platform into an accessible, interactive and low-cost form generation kit, rapidly evaluating the performance of potential design options in the early design stage. As indicated in this research, environmental simulation can be a decision-making tool, in- tegrating the concept of continuity into the design process.

title	Material Active Geometry - Constituting Programmable Materials for Responsive Building Skins
doi	https://doi.org/10.52842/conf.ecaade.2016.1.639

summary	This paper is part of a body of research developing an exploratory dialogue between the built form and the environment, via experimentation with performative geometry and material. Here, geometry is considered a design material with the specific capacity to contribute to the performative aspects and kinetic capabilities of building skins.This work opens with a review of emerging opportunities for architects to design materials. It then discusses the concept of Material Active Geometry (MAG) as a means of designing new properties for existing materials. This is followed by a discussion of MAG principles that inform the concepts of flexibility and rigidity in a 3D-printed textile called Flexible Textile Structure (FTS). This research characterizes two FTS types and discusses their potential to be employed in building skins; it also considers combinatory approaches to computational models and physical prototyping. The work concludes with a discussion of the advantages of using FTS, and provides a trajectory for future research in the field of responsive materials and systems.

summary	While nonlinear concepts are widely applied in analysis and generative design in architecture, they have not yet convincingly translated into the material realm of fabrication and construction. As the gap between digital design model, shop drawing, and fabricated result continues to diminish, we seek to learn from fabrication models and natural systems that do not separate code, geometry, pattern, material compliance, communication, and form, but rather operate within dynamic loops of feedback, reciprocity, and generative fabrication. Three distinct, but connected problems: 1) Robotic ink drawing; 2) Robotic wine pouring and object detection; and 3) Dynamically Adjusted Extrusion; were addressed to develop a toolkit including software, custom digital design tools, and hardware for robotic fabrication and user interaction in cyber-physical contexts. Our primary aim is to simplify and consolidate the multiple platforms necessary to construct feedback networks for robotic fabrication into a central and intuitive programming environment for both the advanced to novice user. Our experimentation in prototyping feedback networks for use with robotics in design practice suggests that the application of this knowledge often follows a remarkably consistent profile. By exploiting these redundancies, we developed a support toolkit of data structures and routines that provide simple integrated software for the user-friendly programming of commonly used roles and functionalities in dynamic robotic fabrication, thus promoting a methodology of feedback-oriented design processes.

title	Prototyping a Temporospatial Simulation Framework:Case of an Ottoman Insane Asylum
doi	https://doi.org/10.52842/conf.ecaade.2016.2.485

summary	Effectively communicating the history of a complex building site using only conventional presentation techniques can be limiting. It is a challenge to present temporal changes in the site simultaneously within a spatial framework. Whereas 2D drawings typically used in architectural historical scholarship are many times cleaned abstractions, 3D models might create an illusion of "recreated reality." Both representation types distance the reader from the primary sources rather than being a mechanism to bring the reader closer to the sources. This paper reports on an interactive simulation of a fin-de-siecle Ottoman insane asylum in Istanbul. Our response to these challenges incorporates to the simulation both the temporal aspect (spanning the life of the asylum and the daily life within) and primary documents by using temporally aware 3D models and keyed descriptive markers for building programming.

summary	This paper explains a method will be used during a workshop for constructing complex-curved geometry with quad edge panels. In this workshop, we demonstrate that quad-edge mesh data structure can efficiently be used to construct complex large shapes. With hands-on experiments, we will show a vast variety of shapes can be constructed using square, rectangular, parallelogram and extruded-line shaped panels. In addition, using a system we have recently developed to unfold polygonal mesh, we will demonstrate how desired shapes can be constructed by using laser-cut quadrilateral panels. This approach is particularly suitable to construct complicated sculptural and architectural shapes from anisotropic materials that can only be bended in one direction.

summary	This research documents our initial experiences of using a new type of collaborative, industrial robot in the area of architecture, design, and construction. The KUKA LBR-iiwa differs from common robotic configurations in that it uses seven axes with integrated force-torque sensors and can be programmed in the Java programming language. Its force-sensitivity makes it safe to interact with, but also enables entirely new applications that use hand-guiding and utilize the force-sensors to compensate for high tolerances on building sites, similar to how we manually approach assembly tasks. Especially for the creative industry, the Java programming opens up completely new applications that would have previously required complex bus systems or industrial data interfaces. We will present a series of realized projects that showcase some of the potential of this new type of collaborative, safe robot, and discuss the advantages and limitations of the robotic system.

summary	This project explores the advantages of employing continuum material topology optimization in a 3D non-standard lattice structure through fiber additive manufacturing processes (Figure 1). Additive manufacturing (AM) has gained rapid adoption in architecture, engineering, and construction (AEC). However, existing optimization techniques often overlook the mechanical anisotropy of AM processes, resulting in suboptimal structural properties, with a focus on layer-by-layer or planar processes. Materials, processes, and techniques considering anisotropy behavior (Kwon et al. 2018) could enhance structural performance (Xie 2022). Research on 3D printing materials with high anisotropy is limited (Eichenhofer et al. 2017), but it holds potential benefits (Liu et al. 2018). Spatial lattices, such as space frames, maximize structural efficiency by enhancing flexural rigidity and load-bearing capacity using minimal material (Woods et al. 2016). From a structural design perspective, specific non-standard lattice geometries offer great potential for reducing material usage, leading to lightweight load-bearing structures (Shelton 2017). The flexibility and freedom of shape inherent to AM offers the possibility to create aggregated continuous truss-like elements with custom topologies.

summary	Bamboo is a high potential alternative solution for substi- tuting industrial material with its natural characteristics, economical and environmental aspects. However, one of the biggest challenges for natural materials to be used in computational designed is the control- lability due to its unevenness nature. The other gap is the lack of ma- terial parameters that might be bridged by analysing data acquired from conventional tests. This research studied the raw bamboo strip and its natural forming from bending, by using sampling points and curvature reconstruction. The parametric models of bamboo strips were then constructed to represent its material behaviours for form prediction, material selection, and simulation in parametric design. It also serves as an assistive method for material selection when crafting with bamboo bend.
