summary	Since 1985 the Computer-Aided Architectural Design Futures Foundation has fostered high level discussions about the search for excellence in the built environment through the use of new technologies with an exploratory and critical perspective. In 2015, the 16th CAAD Futures Conference was held, for the first time, in South America, in the lively megalopolis of Sao Paulo, Brazil. In order to establish a connection to local issues, the theme of the conference was "The next city". The city of Sao Paulo was torn down and almost completely rebuilt twice, from the mid 1800s to the mid 1900s, evolving from a city built in rammed-earth to a city built in bricks and then from a city built in bricks to a city built in concrete. In the 21st century, with the widespread use of digital technologies both in the design and production of buildings, cities are changing even faster, in terms of layout, materials, shapes, textures, production methods and, above all, in terms of the information that is now embedded in built systems.Among the 200 abstracts received in the first phase, 64 were selected for presentation in the conference and publication in the Electronic Proceedings, either as long or short papers, after 3 tough evaluation stages. Each paper was reviewed by at least three different experts from an international committee of more than 80 highly experienced researchers. The authors come from 23 different countries. Among all papers, 10 come from Latin-American institutions, which have been usually under-represented in CAAD Futures. The 33 highest rated long papers are also being published in a printed book by Springer. For this reason, only their abstracts were included in this Electronic Proceedings, at the end of each chapter.The papers in this book have been organized under the following topics: (1) modeling, analyzing and simulating the city, (2) sustainability and performance of the built environment, (3) automated and parametric design, (4) building information modeling (BIM), (5) fabrication and materiality, and (6) shape studies. The first topic includes papers describing different uses of computation applied to the study of the urban environment. The second one represents one of the most important current issues in the study and design of the built environment. The third topic, automated and parametric design, is an established field of research that is finally becoming more available to practitioners. Fabrication has been a hot topic in CAAD conferences, and is becoming ever more popular. This new way of making design and buildings will soon start affecting the way cities look like. Finally, shape studies are an established and respected field in design computing that is traditionally discussed in CAAD conferences.

summary	The paper aims to address methods of realizing computationally generated self-organizing systems on a one-to-one scale with the employment of a singular material system. The case study described in this paper is the outcome of an investigation which has explored earth scaffolding, fabric form-work, and concrete materiality during an international three-week architecture workshop. Real-time generative form-finding methods based on branching and bundling systems in nature have been developed and simulated in an open-source programming environment. The outcome of the simulation stage has been analyzed structurally via Finite Element Analysis (FEA), results of which have served as inputs for the fine-tuning of the simulation. Final three-dimensional geometry has been fabricated by employing fabric, essentially forming the fabric form-work. Fabric form-work is then laid on top of the earth scaffolding, followed by the process of concrete casting. From a pedagogical point of view, the research focuses on the integration of digital design techniques between various design/architecture/analysis platforms combined with basic and advanced techniques of construction within a limited time frame.abstract here by clicking this paragraph.

title	C-Lith: Carbon Fiber Architectural Units
doi	https://doi.org/10.52842/conf.acadia.2015.069
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. 69-79
summary	C-LITH is the reconsideration of the architectural building unit through the exploration of new composite techniques and materials. Our project develops individual compo- nents that exploit the strength, lightness, and variability possible with carbon ber laments when paired with computation, digital fabrication, and hand assembly. Traditionally, architectural units made of brick or concrete are small and multiple, heavy, dif cult to vary, and are much better in compression than tension. Using carbon ber laments to create variable units allows for larger individual units that can vary in both shape and structural performance as needed. Our units, developed through winding pre-preg carbon ber tow around disposable molds, bene t structurally from the quasi-isotropic properties that are developed through the winding patterns. The specific structural capacities of the units remain to be understood through further testing and analysis, which falls outside the scope of this current research. At this junction, structural capacities have been determined empirically, i.e. will it stand? Most importantly, as a formal study, our units address the use of carbon ber at the scale of architectural production. A majority of the effort involved in materializing C-LITH was the development of a two-fold prototypical manufacturing process that produces the components and assembly. For this we invented a method to quickly and cheaply construct variable cardboard molds that could withstand the wound casting and baking steps, but could also be easily weakened through water immersion to be removed. For the assembly we developed a rigid dummy-jig system to hold the joint plates in position with a high level of precision but could also incrementally absorb the adjustment errors unavoidable in hand assembly systems. Using a simple pin connection the resultant structures can be easily disassembled for transportation and reassembly elsewhere.

summary	Voxelbeam explores precedents in the optimization of architectural structures, namely the Sydney Opera house Arup beam. The authors research three areas crucial to conceiving an innovative contemporary reinterpretation of the beam: A shift in structural analysis techniques from analytical to numerical models such as topology optimization, the fundamental differences between digital and analog representations of structural forces, and the translation of structural analysis data into methods for digital fabrication. The research aims to re-contextualize the structural beam within contemporary digital platforms, explores the architectural implications of topology optimization, and proposes two fabrication strategies based on the analysis results – including automated off-site pre-casting and multi-material 3d printing.

summary	The prevalent mode of shape grammar output is a two-dimensional drawing grammar. For architectural applications, these two- dimensional shape rules can hold a variety of interpretations in three-dimensional space. This work translates an existing grammar from a manual two-dimensional drawing grammar to an automated three-dimensional building grammar to explore the challenges and opportunities that this translation suggests in the larger context of shape computation. The case study considered here is a grammar interpreting John Portman’s architectural language as defined by the house Portman identifies as emblematic of his design principles, his 1964 personal residence Entelechy I.

title	SHOPGENERATOR v2:Automated Design, Analysis and Optimization of Shopping Layouts

summary	In shop design a common method to maximize sales is to manipulate the customers through spatial arrangements of shelves and products. The aim of this practice is that shoppers have to spend a long time in the store and pass a high quantity of products. Using this technique requires a lot of empirical analysis of POS (point of sale) data and experimentation with product and shelf arrangements, while not upsetting the customers by guiding them through a “shopping maze”. For this reason we developed a tool that semi-automatically - just a couple of inputs concerning the type of shop are required - creates different shopping layouts which are later analyzed and optimized for visibility and product placement. This tool aims to support shop designers in an early planning stage. This is done by creating and testing a large number of different shopping layouts without having to conduct experiments in an actually built environment..

summary	Today, human activities constitute the primary environmental impact on the planet. In this context, commitments to sustainability, or minimization of damage, prove insufficient. To develop regenerative, futuring capabilities, architectural design needs to extend beyond the form and function of things and engage with the management of complex systems. Such systems involve multiple types of dynamic phenomena – biotic and abiotic, technical and cultural – and can be understood as living. Engagement with such living systems implies manipulation of pervasive and unceasing change, irrespective of whether it is accepted by design stakeholders or actively managed towards homeostatic or homeorhetic conditions. On one hand, such manipulation of continuity requires holistic and persistent design involvements that are beyond natural capabilities of human designers. On the other hand, practical, political or creative implications of reliance on automated systems capable of tackling such tasks is as yet underexplored. In response to this challenge, this paper considers an experimental approach that utilised methods of critical making and speculative designing to explore potentials of autonomous architecture. This approach combined 1) knowledge of animal architecture that served as a lens for rethinking human construction and as a source of alternative design approaches; 2) practices of creative computing that supported speculative applications of data-driven and performance-oriented design; and 3) techniques of robotics and mechatronics that produced working prototypes of autonomous devices that served as props for critical thinking about alternative futures.

title	Expanding the Material Possibilities of Lightweight Prefabrication in Concrete Through Robotic Hot-Wire Cutting - Form, Texture and Composition
doi	https://doi.org/10.52842/conf.ecaade.2015.2.341
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 341-351
summary	In recent years, digital fabrication technologies have enabled renewed explorations into traditional materials, with innovative results. This paper focuses on concrete and on the potentials of a specific technology: robotic hot-wire cutting for the production of expanded polystyrene (EPS) formwork. Academia and industry have explored this process recently but the number of works built with this technology is reduced and the general concrete prefabrication industry has been slow to adopt it. In this context, this paper analyzes the use of EPS in the production of concrete formwork by reviewing its application in contemporary examples. In order to develop a clear assessment of the possibilities of expanding prefabrication in concrete using robotic hot-wire cutting, this paper also documents a set of practical experiments developed in the laboratory, addressing three material challenges: form; texture and composition. This research involved the design, formwork production and casting of concrete elements to explore the limits and characterize the process of robotic hot-wire fabrication in the context of concrete prefabrication. By recognizing the different approaches present in contemporary examples and in the explored practical experiments, we point out the advantages and limitations of using hot-wire cutting, and develop the reasons behind its limited application in practice.

title	Transient Thermal Exchange and Developmental Form for Tactile Surfaces
doi	https://doi.org/10.52842/conf.acadia.2015.431
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. 431-441
summary	The idea of an emergent or generative form based on repeating rules of development borrowed from the field of developmental biology has provided fertile ground for inspiration for architectural theory and computational design. With simple constraints developed iteratively, complex geometry and form generation can be distilled down to a list of developmental rules or functions in order to deterministically generate form. The ideas and illustrations of naturalists on organic form and developmental biology leading back to the turn of the 20th c., such as the work of D'arcy Wentworth Thompson and Ernst Haeckel, have inspired architects from Louis Sullivan all the way to contemporary generative design. This study revisits this design tradition of biomimetic geometries based on deterministic rules for the iterative development of forms based on biological analogs and models for growth. A series of semi-regular compound patterns were developed using parametric modeling and iterative rules. These geometries were then applied to surface topologies as a decorative tactile embellishment resulting in complex thermodynamic conditions. A series of physical prototypes where then developed with different high-relief patterns and pattern densities. Positive prototype geometries were then produced using stereolithography for casting plaster molds for the production molding of finished ceramic pieces for thermal analysis using digital thermography. By studying the performance of these complex geometries as physical prototypes under controlled experimentation, high-relief surfaces and the resulting thermodynamic conditions can be understood not just qualitative experience, but also quantitatively through measured performance metrics and innovative tools for analytical analysis.

title	A User Interface for Parametric Architectural Design Reviews

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	On-site Robotic Assembly of Double-curved Self-supporting Structures

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	Spatial Nets: the Computational and Material Study of Reticular Geometries
doi	https://doi.org/10.52842/conf.acadia.2015.123

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	Modulating Thermal Mass Behavior Through Surface Figuration
doi	https://doi.org/10.52842/conf.acadia.2017.202

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	Novel digital fabrication platforms enable the design and construction of materially sophisticated structures with high spatial resolution in manufacturing. However, virtual-to-physical workflows and their associated software environments are yet to incorporate such capabilities. Our research sets the stage for seamless physical feedback workflows across media, disciplines and scales. We have coined the term Fabrication Information Modeling (FIM) to describe this approach. As preliminary methods we have developed four computational strategies for the design and digital construction of custom systems. These methods are presented in the context of specific design challenges and include a biologically driven fiber construction algorithm; an anatomically driven shell-to-wearable translation protocol; an environmentally-driven swarm printing system; and a manufacturing-driven hierarchical fabrication platform. We discuss and analyze these four challenges in terms of their capabilities to integrate design across media, disciplines and scales through concepts such as multi-dimensionality, media-informed computation and trans-disciplinary data.

title	Recapitulation in Generating Spatial Layouts
doi	https://doi.org/10.52842/conf.caadria.2015.199
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. 199-207
summary	The noted 19th century biologist, Ernst Haeckel, put forward the idea that the growth (ontogenesis) of an organism recapitulated the history of its evolutionary development. While this idea is defunct within biology, the idea has been promoted in areas such as education (the idea of an education being the repetition of the civilizations before). In the research presented in this paper, recapitulation is used as a metaphor within computer-aided design as a way of grouping together different generations of spatial layouts. In most CAD programs, a spatial layout is represented as a series of objects (lines, or boundary representations) that stand in as walls. The relationships between spaces are not usually explicitly stated. A representation using Lindenmayer Systems (originally designed for the purpose of modelling plant morphology) is put forward as a way of representing the morphology of a spatial layout. The aim of this research is not just to describe an individual layout, but to find representations that link together lineages of development. This representation can be used in generative design as a way of creating more meaningful layouts which have particular characteristics. The use of genetic operators (mutation and crossover) is also considered, making this representation suitable for use with genetic algorithms.

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.

summary	The number of variables acting upon urban landscapes is numerous and interconnected, closely resembling complex systems in constant dynamic transformation. Current analytical methods and descriptions of the city are domain specific, limited in scope, and discretize the city into quantifiable individual representations, resulting in an equally limited urban policy and design. If we are to produce urban systems capable of contributing to the robustness and resiliency of cities, we ought to understand and represent the comprehensive network of actors that construct contemporary urban landscapes. On one hand, the natural sciences approach the analysis of complex systems by primarily focusing on the development of models capable of describing their stochastic formation, remaining agnostic to the contextual properties of their individual components and oftentimes discretizing the otherwise continuous relationships among parts. signers work in groups. They need to share information either synchronously or asynchronously as they work with parametric modeling software, as with all computer-aided design tools. Receiving information from collaborators while working may intrude on their work and thought processes. Little research exists on how the reception of design updates influences designers in their work. Nor do we know much about designer preferences for collaboration. In this paper, we examine how sharing and receiving design updates affects designers’ performances and preferences. We present a system prototype to share changes on demand or in continuous mode while performing design tasks. A pilot study measuring the preferences of nine pairs of designers for different combinations of control modes and design tasks shows statistically significant differences between the task types and control modes. The types of tasks affect the preferences of users to the types of control modes. In an apparent contradiction, user preference of control modes contradicts task performance time.

title	Generative Design for Folded Timber Structures
doi	https://doi.org/10.52842/conf.caadria.2015.673
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. 673-682
summary	Folding structures belong to the group of lightweight structural systems, which often consist of polygonal elements like triangles or quadrangles. Folding structures whose construction is made out of cross-laminated timber (CLT) panels represent an innovative step in the timber industry, which has many advantages. CLT panels can be used simultaneously as supporting elements and as finishing building envelopes. There are many prefabrication possibilities, high efficient material consumption, low production and assembly costs, and it has environmental advantages over conventional materials used for folding structure like concrete, metal or glass. CLT folding structures are not sufficiently explored. One of the reasons may lie in the fact of limited design possibilities, which includes the specificity of CLT capacity. Another reason is maybe the inability to use standard wooden connectors to transfer the forces along the thin linear edges where the panels are supported. The aim of this paper is to present design possibilities through parametric modelling using the characteristics of CLT. Using the example of a wooden theatre stage we will present results of our research.
