title	Social Sensory Architectures: Articulating Textile Hybrid Structures for Multi-Sensory Responsiveness and Collaborative Play
doi	https://doi.org/10.52842/conf.acadia.2015.263
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. 263-273
summary	This paper describes the development of the StretchPLAY prototype as a part of the Social Sensory Surfaces research project, focusing on the design of tactile and responsive environments for children with Autism Spectrum Disorder (ASD). The project is directed specifically at issues with sensory processing, the inability of the nervous system to filter sensory input in order to indicate an appropriate response. This can be referred to as a “traffic jam” of sensory data where the intensity of such unfiltered information leads to an over-intensified sensory experience, and ultimately a dis-regulated state. To create a sensory regulating environments, a tactile structure is developed integrating physical, visual and auditory feedback. The structure is defined as a textile hybrid system integrating a seamless knitted textile to form a continuous topologically complex surface. Advancements in the fabrication of the boundary structure, of glass-fiber reinforced rods, enable the form to be more robustly structured than previous examples of textile hybrid or tent-like structures. The tensioned textile is activated as a tangible interface where sensing of touch and pressure on the surface triggers ranges of visual and auditory response. A specific child, a five-year old girl with ASD, is studied in order to tailor the technologies as a response to her sensory challenges. This project is a collaboration with students, researchers and faculty in the fields of architecture, computer science, information (human-computer interaction), music and civil engineering, along with practitioners in the field of ASD-based therapies.

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	Spatial Nets: the Computational and Material Study of Reticular Geometries
doi	https://doi.org/10.52842/conf.acadia.2015.123
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. 123-135
summary	Reticular systems are in many aspects a distinct taxonomy of volumetric geometries. In comparison with the conventional embodiment of a ‘volume’ that encapsulates a certain quantity of space with a shell reticular geometries emerge from the accumulation of micro elements to define a gradient of space. Observed in biological systems, such structures result from their material properties and formation processes as well as often ‘simple’ axioms that produce complex results. In micro or macro levels, from forest tree canopies to plant cell walls these porous volumes are not shaped to have a singular ‘solution’ for a purpose; they provide the fundamental geometric characteristics of a ‘line cloud’ that is simultaneously flexible in response to its environment, porous to other systems (light, air, liquids) and less susceptible to critical damage. The porosity of such systems and their volumetric depth also result in kinetic spatial qualities in a 4D architectural space. Built upon a ‘weaving’ organization and the high performance material properties of carbon fiber composite, this research focuses on a formal grammar that initiates the complex system of a reticular volume. A finite ‘lexical’ axiom is consisted of the basic characters of H, M and L responding to the anchor points on the highest, medium and lower levels of the extruding loom. The genome thus produces a string of data that in the second phase of programming are assigned to 624 points on the loom. The code aims to distribute the nodes across the flat line cloud and organize the sequence for the purpose of overlapping the tensioned strings. The virtually infinite results are then assessed through an evolutionary solver for confining an array of favorable results that can be then selected from by the designer. This research focuses on an approximate control over the fundamental geometric characteristics of a reticular system such as node density and directionality. The proposal frames the favorable result of the weave to be three-dimensional and volumetric – avoiding distinctly linear or surface formations.

title	Toward a Behavioral Design System: An Agent-Based Approach for Polygonal Surfaces Structures
doi	https://doi.org/10.52842/conf.acadia.2015.161
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. 161-172
summary	The following research investigates the development of an agent-based design method as an integrative design tool for polygonal surface structures. The aim of this research is to develop a computational tool that self-organizes the emergence of polygonal surface structures from interaction between its constitutive lattices. This research focuses on the ethological level of morphogenesis that is relevant to the animal or insect societies, whereby agents mediate the material organizations with environmental aspects. Meanwhile, behavior-based approaches are investigated as a bottom-up system to develop a computational framework in which the lower-level features constantly interact. The lower-level features such as material properties (e.g., geometric descriptions) are abstracted into building blocks or agents to construct the agent’s morphology. The abstracted principles, which define the agent’s morphology, are aggregated into a generative tool to explore the emergent complexities. This exploration coupled with the generative constraint mechanisms steers the collective agents system toward the cloud of solutions; hence, the collective behaviors of agents constitute the polygonal surface structures. This polygonal system is a bottom up approach of developing the complex surface that emerges through topological and topographical interaction between cells and their surrounding environment. Subsequently, the integrative system is developed through agent-based parametric modelling, in which the knowledge-based system as a top-down approach is substituted with the agent system together with its morphological features and significant behaviors.

summary	An algorithm is a process of addressing a problem in a finite number of steps. In the context of architectural design, algorithmic thinking means taking on an interpretive role to understand the results in relation to design criteria, knowing how to modify the code to explore new options, and speculating on further design potentials. The application of algorithms within architecture often addresses the developed design stages, primarily to optimise structure, test environmental performance or to resolve complex construction. This research aims to explore algorithmic tools with a focus on early stage design. This design stage is often developed using traditional processes and is where algorithmic applications have been less successfully executed. The objectives are to algorithmically explore the areas of space planning, programme layout, form finding and form optimisation within early stage architectural design. Through the combination of a range of diverse algorithms, this research has an ultimate aim of integrating a computational workflow into practice at the early design stage.

title	Towards A Motion Grammar for Robotic Stereotomy
doi	https://doi.org/10.52842/conf.caadria.2015.723
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. 723-732
summary	This paper presents progress towards the definition of a motion grammar for robotic stereotomy. It describes a vocabulary of motions able to generate complex forms by cutting, slicing, and/or carving 3-D blocks of material using a robotic arm and a custom made cutting tool. While shape grammars usually deal with graphical descriptions of designs, a motion grammar seeks to address the 3-D harmonic movements of machine, tool, and material substrate choreographically, suggesting motion as a generative vehicle of exploration in both designing and making. Several models and prototypes are presented and discussed.

summary	Nowadays, there is a growing interest in buildings' envelops presenting complex geometries and patterns. This interest is related with the use of new design tools, such as Generative Design, which promotes a greater design exploration. In this paper we discuss and illustrate a structured and systematic computational framework for the generation of facade designs. This framework includes (1) a classification of facades into different categories that we consider computationally relevant, and (2) an identification and implementation of a set of algorithms and strategies that address the needs of the different designs.

title	Anisoptera; Anisopteran Deformation and the Latent Geometric Patterns of Wood Envelopes
doi	https://doi.org/10.52842/conf.acadia.2015.047
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. 47-56
summary	Advancements in technologies provide Architects, today, with the means to expose new expressive forms using traditional materials. It is therefore possible to design dynamic actuating systems, where several different expressions, or differentiations inherent in the same material, are able to modify its topology and enhance its properties. Wood, traditionally used in construction, is given static expression during its life cycle, where an alignment, or assembly detail, helps retain its original shape. This research outlines the integration of specific and individual anatomical information of wood during the design process. It aids in utilizing the analyzed biological variability and natural irregularities of wood within a material-based architecture, in view of developing a lightweight, and light-filtering dynamic skin. Additionally, the research helps to explore an understanding of the differentiated material composition of wood as its major capacity, rather than its deficiency. Moreover, it analyzes form, material, and structure, as complex interrelations that are embedded in, and explored through an integral design process that seeks to employ typically disregarded, highly differentiated flat materials, in view of enhancing their latent dimensional deformation potential. The main focus of this research is to explore that latent geometric deformation of emerging patterns based on an array of heterogeneous wood veneers in relation to their Hygroscopic and Anisotropic properties. These properties are expressed through a set of flat skins and Mobius arrangements, articulating complex geometric ranges that reveal additional properties, such as bendability and flexibility.

title	Protocol of Error: The design and construction of a bending-active gridshell from natural bamboo
doi	https://doi.org/10.52842/conf.caadria.2016.415
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. 415-424
summary	This paper advocates alternative methods to overcome the impossibility of realising ‘perfect’ digital designs. It discusses Hong Kong’s 2015 ‘ZCB Bamboo Pavilion’ as a methodological case study for the design and construction of architecture from unprocessed natu- ral bamboo. The paper critically evaluates protocols set up to deal with errors resulting from precise digital design systems merging with inconsistent natural resources and onsite craftsmanship. The paper starts with the geometric and tectonic description of the project, illus- trating a complex and restrictive construction context. Bamboo’s unique growth pattern, structural build-up and suitability as a bending- active material are discussed and Cantonese bamboo scaffolding craftsmanship is addressed as a starting point for the project. The pa- per covers protocols, construction drawings and assembly methods developed to allow for the incorporation and of large building toler- ances and dimensional variation of bamboo. The final as-built 3d scanned structure is compared with the original digital model. The pa- per concludes by discussing the necessity of computational architec- tural design to proactively operate within a field of real-world inde- terminacy, to focus on the development of protocols that deal with imperfections, and to redirect design from the virtual world towards the latent opportunities of the physical.

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	Modulating Thermal Mass Behavior Through Surface Figuration

source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 202-211
summary	This research builds upon a previous body of work focused on the relationship between surface geometry and heat transfer coefficients in thermal mass passive systems. It argues for the design of passive systems with higher fidelity to multivariable space between performance and perception. Rooted in the combination of form and matter, the intention is to instrumentalize design principles for the choreography of thermal gradients between buildings and their environment from experiential, spatial and topological perspectives (Figure 1). Our work is built upon the premise that complex geometries can be used to improve both the aesthetic and thermodynamic performance of passive building systems (Cupkova and Azel 2015) by actuating thermal performance through geometric parameters primarily due to convection. Currently, the engineering-oriented approach to the design of thermal mass relies on averaged thermal calculations (Holman 2002), which do not adequately describe the nuanced differences that can be produced by complex three-dimensional geometries of passive thermal mass systems. Using a combination of computational fluid dynamic simulations with physically measured data, we investigate the relationship of heat transfer coefficients related to parameters of surface geometry. Our measured results suggest that we can deliberately and significantly delay heat absorption re-radiation purely by changing the geometric surface pattern over the same thermal mass. The goal of this work is to offer designers a more robust rule set for understanding approximate thermal lag behaviors of complex geometric systems, with a focus on the design of geometric properties rather than complex thermal calculations.

summary	The purpose of this paper is to present a work in progress pertaining to drone pose estimation and flight calibration. This paper intends to underline the increasing importance of determining alternative path planning instruments through accurate localization for Unmanned Aerial Vehicles (UAVs) with the purpose of achieving complex flight operations for the emerging applications of autonomous robotics in surveying, design, fabrication, and on-site operations. This research is based on the implementation of novel technologies such as Augmented Reality (AR), Robot Operating System (ROS), and computational approaches to define a drone calibration methodology, leveraging existing methods for drone path planning. Drones are equipped with measurement systems to provide geo-location and time information such as onboard Global Positioning System (GPS) sensors, and Inertial Measurement Units (IMU). As stated in previous research, to increase navigation capabilities, measurements and data processing algorithms have a critical role (Daponte et al. 2015). The outcome of this work in progress showcases valuable results in calculating and assessing accurate positioning for UAVs, and developing data exchanges in transmission, reception, and tracking.

summary	The digital age is facilitating an ever increasing trend of globalized language and culture. Environmental issues are no longer a static concept as climate change and population growth force concepts of adaptability. What does this mean for the academy? How do we educate students to contemplate future urban scenarios and make some organization out of this more dynamic, complex future? The following paper seeks to disseminate a spring 2014 design studio at The University of Arizona where these issues were addressed, with Mexico City as a test bed. Computation has become a vital tool in the organizational process of these complex issues and big data. Various digital tools and platforms were explored in the studio to determine which ones would be most useful in modeling, mapping, designing and processing some of the complex relationships that are present in urban environments today.

summary	With an exponential increase in the possibilities of computation and computer-controlled fabrication, high density information is becoming a reality in digital design and architecture. However, construction methods and industrial fabrication processes have not yet been reshaped to accommodate the recent changes in those disciplines. Although it is possible to build up complex simulations with millions of particles, the simulation is often disconnected from the actual fabrication process. Our research proposes a bridge between both stages, where one drives the other, producing a smooth transition from design to production. A particle in the digital domain becomes a drop of material in the construction method.The architect's medium of expression has become much more than a representational tool in the last century, and more recently it has evolved even beyond a series of rules to drive from design to production. The design system is the instruction itself; embedding structure, material and tectonics and gets delivered to the very end of the construction chain, where it gets materialised. The research showcased in this paper investigates tectonic systems associated with large scale 3D printing and additive manufacturing methods, inheriting both material properties and fabrication constraints at all stages from design to production. Computational models and custom design software packages are designed and developed as strategies to organise material in space in response to specific structural and logistical input.Although the research has developed a wide spectrum of 3D printing methods, this paper focuses only on two of the most recent projects, where different material and computational logics were investigated. The first, titled Filamentrics, intends to develop free-form space frames, overcoming their homogeneity by introducing robotic plastic extrusion. Through the use of custom made extruders a vast range of high resolution prototypes were developed, evolving the design process towards the fabrication of precise structures that can be materialised using additive manufacturing but without the use of a layered 3D printing method. Instead, material limitations were studied and embedded in custom algorithms that allow depositing material in the air for internal connectivity. The final result is a 3x2x2.5m structure that demonstrates the viability of this construction method for being implemented in more industrial scenarios.While Filamentrics is reshaping the way we could design and build light weight structures, the second project Microstrata aims to establish new construction methods for compression based materials. A layering 3D printing method combines both the deposition of the binder and the distribution of an interconnected network of capillaries. These capillaries are organised following structural principles, configuring a series of channels which are left empty within the mass. In a second stage aluminium is cast in this hollow space to build a continuous tension reinforcement.

summary	We analyse the problem of creating didactic material for teaching and evaluating mathematics in the first year of a School of Architecture. By using visual programming, science professor used codes (formulae) to represent in a software their proposals, instead of drawing them themselves. Through this experience we create a database of codes with computational solutions that allows faculty to modify, reuse, visualise and print in the same platform that she students will use while developing their designs. In this way we aim to maximise the link between mathematics and design as fundamental base for the control of complex shapes.

summary	The animation and visual effects industry is producing advanced software capable of generating realistic behaviours faster than ever by using algorithms that approximate the physics of the real world. There is an opportunity to utilize these software to support performance-based conceptual design for complex simulations such as Computational Fluid Dynamics (CFD). This paper investigates a method of performing windflow simulation using an animation software that implements an Eulerian based smoke solver. These simulations run orders of magnitude faster than the similar simulations in dedicated high-end CFD applications. The paper compares the animated simulation results to a benchmark case with measured wind-tunnel data. The results indicate that at certain points in the animation, the accuracy is very high. However, the challenge lies in predicting best frame at which to stop the animation. The paper ends with a discussion of how this challenge might be tackled.

title	Super-details: Integrated patterns from 3D printing processes to performance-based design

summary	Performance-based architecture has predominately been influenced by computational advances in simulating complex organizations. The advent of 3D printing, however, has introduced a new approach to generate complex forms, which is redirecting focus from shape-centric design to material design, namely, innovative structures and properties generated by the process itself. This article investigated the multiscale approach potential to design using extrusion-based 3D printing techniques that offer novel geometric organizations that conform to desired performance. It was found that 3D printed toolpaths adapted to extrusion-based systems render an anisotropic behavior to the architectural object that is best optimized by designing tessellated surfaces as the primary structural shape from which small-scale periodic surfaces can be embedded within a larger geometric system.

title	Pattern, cognition and spatial information processing: Representations of the spatial layout of architectural design with spatial-semantic analytics
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 484.
summary	In this paper, we review and extend the idea of Alexander’s “pattern language”, especially from the viewpoints of complexity theories, information systems, and human-computer interaction, to explore spatial cognition-based design representations for “intelligent and adaptive/interactive environment” in architecture and urban planning. We propose a theoretic framework of design patterns “with spatial information processing”, and attempt to incorporate state-of-the-art computational methods of information visualization/visual analytics into the conventional CAAD approaches. Focused on the spatial-semantic analytics, together with abstract syntactic pattern representation, by using “spatial-semantic aware” graph grammar formalization, i.e., Spatial Graph Grammars (SGG), the relevant models, algorithms and tool are proposed. We testify our theoretic framework and computational tool VEGGIE (a Visual Environment of Graph Grammar Induction Engineering) by using actual architectural design works (spatial layout exemplars of a small office building and the three house projects by Frank Lloyd Wright) as study cases, so as to demonstrate our proposed approach for practical applications. The results are discussed and further research is suggested.

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.
