summary The Emergent Reefs project thrives on the potential that emerge from a coherent utilization of the environment’s inherent ecological structure for its own transformation and evolution, using an approach based on digitally simulated ecosystems and sparkled by the possibilities and potential of large-scale 3D printing technology. Considering tourism as an inevitable vector of environmental change, the project aims to direct its potential and economic resources towards a positive transformation, providing a material substrate for the human-marine ecosystem integration with the realization of spaces for an underwater sculpture exhibition. Such structures will also provide a pattern of cavities which, expanding the gradient of microenvironmental conditions, break the existing homogeneity in favor of systemic heterogeneity, providing the spatial and material preconditions for the repopulation of marine biodiversity. Starting from a digital simulation of a synthetic local ecosystem, a generative technique based on multi-agent systems and continuous cellular automata (put into practice from the theoretical premises in Alan Turing’s paper “The Chemical basis of Morphogenesis” through reaction-diffusion simulation) is implemented in a voxel field at several scales giving the project a twofold quality: the implementation of reaction diffusion generative strategy within a non-isotropic 3-dimensional field and integration with the large-scale 3D printing fabrication system patented by D-Shape®. Out of these assumptions and in the intent of exploiting the expressive and tectonic potential of such technology, the project has been tackled exploring voxel-based generative strategies. Working with a discrete lattice eases the simulation of complex systems and processes across multiple scales (including non-linear simulations such as Computational Fluid-Dynamics) starting from local interactions using, for instance, algorithms based on cellular automata, which then can be translated directly to the physical production system. The purpose of Emergent-Reefs is to establish, through strategies based on computational design tools and machine-based fabrication, seamless relationships between three different aspects of the architectural process: generation, simulation and construction, which in the case of the used technology can be specified as guided growth.

title Using Situated FBS Ontology to Explore Designers' Patterns of Behavior in Parametric Environments
source CAAD | INNOVATION | PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 23-32
summary Current literature suggests that there is limited empirical evidence supporting the understanding of designers’ behavior or processes in parametric design environments (PDEs). This on-going study explores designers’ patterns of behavior in PDEs and its relationship with design creativity. To achieve this, we introduce the situated function-behavior-structure (FBS) model to develop a customized coding scheme for future protocol studies. This FBS ontological model has been adapted to reflect the characteristics of parametric design. We propose to apply the results of the protocol analysis in identifying three levels of design behavior patterns: behavior patterns derived from design processes, behavior patterns derived from the whole design life-cycle and those derived from the two levels of parametric design activities (design knowledge based activities and rule algorithm based activities). Future experiments and subsequent protocol analysis will apply the coding scheme to identify these behavioral patterns. The relationship with design creativity will then be explored by mapping the identified behavior patterns against the design outcome assessment.

title Formal and Functional Implications of Dynamics-Related Solar Design Schemes
doi https://doi.org/10.52842/conf.acadia.2012.343
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. 343-354
summary In recent years several solar radiation simulation tools have been developed to assist architects in analyzing the performance of existing building designs. However it is often unclear how the results of these analyses can help to generate new solutions and thus be truly beneficial for innovation in sustainable architectural design. Recent developments in open source applications that allow links between energy simulation engines and 3D modeling environments open a new layer of understanding. The possibility to better understand the dynamic interaction between incident solar radiation and building envelopes allows the synthesis of new architectural design-schemes. This paper presents the results of a series of experiments based on the case-study of a mid-latitude single-family house in Taiki-Cho, Japan. The first experiment describes how the incident solar energy interacts with the exposed components of the envelope. The second experiment describes how the energy demand of the building can be partially reduced through the design of passive interventions that are based on the dynamics of the demand. Finally, the third experiment exemplifies how, based on the knowledge extracted from the first two experiments, it is possible to synthesize new dynamics-related solar design-schemes that join passive techniques, active technologies, and formal aspects.

title Generation and Integration of an Aerodynamic Performance Data Base Within the Concept Design Phase of Tall Buildings
doi https://doi.org/10.52842/conf.acadia.2012.087
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.

summary The use of digital design and fabrication technologies in architecture has followed a paradigm shift, which has seen the topology, form and structure of architecture pushed to incorporate areas such as climate, construction, acoustic etc. While these digital technologies are intended to enhance the processes and performance, a discussion of aesthetics has been ignored. Surmising that the use of digital technology enhances the performability and effi ciency aspects of architecture as well as the aesthetics, this research questions what the new relationships and arrangements for structure and ornament are. What are the challenges when structure uses a process-based logic and is sensitive to materiality whereas the aesthetics has a representation-based logic and is not sensitive to materiality? The authors of this paper contribute to this debate by using the notion of tectonic as a platform for gaining and creating knowledge about this issue and examining the issues through the design and prototyping of a Multi-functional Pavilion.

title The representation of type in grammatical design
doi https://doi.org/10.52842/conf.caadria.2012.425
source Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 425–432
summary Grammatical design is useful for the generation of a set of related designs. The concept of type aids designers in generating designs with a specified structure. However, existing studies in grammar are ambiguous in their definition of type in the language of designs generated by a grammar. Extending our previous study of defining style in grammar, this paper provides a formal definition of the concept of type in the language of designs generated by a grammar. This is done with the help of a description scheme which is developed by augmenting grammar primitives and spatial relations with descriptors. The description scheme allows the computation of descriptors for designs generated from grammar thus making possible the comparison of various design types in the language of a grammar. Such a description scheme for defining design types is especially significant for less restricted grammars that generate a large number of designs that are varied in nature. A formal definition of type in grammars allows users to sift through designs with particular features, and thus select desired designs.

summary The emergence of quasi-periodic tiling theories in mathematics and material science is revealing a new class of symmetry, which had never been accessible before. Because of their astounding visual and structural properties, quasi-periodic symmetries can be ideally suited for many applications in art and architecture; providing a rich source of ideas for articulating form, pattern, surface and structure. However, since their discovery, the unique long-range order of quasi-periodic symmetries, is still posing a perplexing puzzle. As rule-based systems, the ability to algorithmically generate these complicated symmetries can be instrumental in understanding and manipulating their geometry. Recently, the discovery of quasi-periodic patterns in ancient Islamic architecture is providing a unique example of how ancient mathematics can inform our understanding of some basic theories in modern science. The recent investigation into these complex and chaotic formations is providing evidence to show that ancient designers, by using the most primitive tools (a compass and a straightedge) were able to resolve the complicated long-range principles of ten-fold quasi-periodic formations. Derived from these ancient principles, this paper presents a computational model for describing the long-range order of octagon-based quasi-periodic formations. The objective of the study is to design an algorithm for constructing large patches of octagon-based quasi-crystalline formations. The proposed algorithm is proven to be successful in producing an infinite and defect-free covering of the two-dimensional plane.

summary As part of our inquiry about the practice of architectural film and animation and where it might go, this paper presents the results of interviews with architects on space, and on animation. We present their rich sense of space, and explain how they structure architectural film and animation. We found that architects wish to convey the subjective impact of design, but don’t know how to connect film editing techniques to architectural ends. Computational design could fill this gap with, for example, drag-and-drop editing patterns.

summary This paper presents a currently on-going research trajectory, investigating integrated design and build work-fl ows using generative design strategies and custom built fabrication devices. The aim of the research, which is being developed through a series of experiments and workshops, is to explore scenarios in which these work-flows can produce emergent architectural structures which are highly adapted towards the intended performance within their specifi c context and site. The research has produced a number of installations and prototypical structures which test the practical and theoretical dimensions of the methodology explored. This paper will introduce intriguing new scenarios in which the architects’ role is focused on an indirect, advanced level of control of the process of design, allowing for a more open-ended method of negotiation between structure, users and environment.

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 Architecture today has come to its most complex form. There are lots of criteria such as fi re safety, structure, sustainability etc… which must be controlled by the designers. To improve the performance and accessibility of buildings, governing bodies publish different codes for each of the different criteria. Buildings must comply with these codes to get a permit for construction. The checking of the buildings according the codes is done manually by code offi cials. This process is time consuming, high in cost and prone to errors. To remedy this problem by using the tools like BIM and AI, systems that can automatically check the code compliance of projects are being developed. In this paper we provide an overview of the structures and capabilities of these systems and present the automated code compliance checking system that we develop for checking building models against some parts of the Turkish Fire Codes.

summary The method proposed in this project addresses the parametric manipulation of a given pattern to respond directly to a pre-defined surface. Continuing the research of Kevin Rotheroe, Yale University and founder of FreeForm Design. Rotheroe has developed a series of studies in material and surface properties. By utilising a proven pattern, the proposed method sets parameters derived from the formal properties of the original pattern and produces a new pattern that is responsive to the curvature of a complex surface. The workflow developed in this research consists of a complex blending of tools in Grasshopper and Gehry Technologies Digital Project. The intent is to achieve the aesthetics and structure offered by Rotheroe’s original research and to add a responsive precision that provides an accurate adaptation of the pattern based on curvature of a specific computationally defined surface.

title Data Sharing for Sustainable Building Assessment
source International Journal of Architectural Computing vol. 10 - no. 4, 555-574
summary Sustainable design assessment requires information, which is aggregated from different phases of a building design, and evaluated according to criteria specified in a ‘sustainable building rating system.’ In the architecture engineering and construction (AEC) domain much of the necessary information is available through open source data standards such as Industry Foundation Classes (IFC). However, no single standard that provides support for sustainability assessment completely suffices as a data structure. This paper explores the augmentation of the Construction Operations Building information exchange (COBie) model, as an intermediary data structure, to bridge between requirements of the Leadership in Energy and Environmental Design (LEED) rating system and a building information model. Development of a general framework for data sharing and information management for LEED assessments is illustrated through an implementation of a prototype using functional databases.The prototype checks and augments available data as needed, which is used to populate LEED submission templates.

summary This article refl ects on the digital reconstruction of the Vinohrady Synagogue in Prague, which was demolished in 1951. Based on an international collaboration through the Erasmus program, expertise derived from other Viennese synagogue reconstructions at TU Vienna was combined with a resource organization methodology developed at KU Leuven. The reconstruction process is carried out using BIM software, which poses some particular attention on the software methodology and model structure, but at the same time illustrates the added value of a BIM approach, when comparing with more traditional CAD modelling systematics. Of particular interest is the approach for modelling complex geometry, integrating with more traditional 2D documents and for visualizing reconstruction assumptions within the 3D model representation.

summary Edible Infrastructures is an investigation into a projective mode of urbanism which considers food as an integral part of a city's metabolic infrastructure. Working with algorithms as design tools, we explore the generative potential of such a system to create an urban ecology that: provides for its residents via local, multi-scalar, distributed food production, reconnects urbanites with their food sources, and de-couples food costs from fossil fuels by limiting transportation at all levels, from source to table. The research is conducted through the building up of a sequence of algorithms, beginning with the ‘Settlement Simulation’, which couples consumers to productive surface area within a cellular automata type computational model. Topological analysis informs generative operations, as each stage builds on the output of the last. In this way we explore the hierarchical components for a new Productive City, including: the structure and programming of the urban circulatory network, an emergent urban morphology based around productive urban blocks, and opportunities for new architectural typologies. The resulting prototypical Productive City questions the underlying mechanisms that shape modern urban space and demonstrates the architectural potential of mathematical modeling and simulation in addressing complex urban spatial and programmatic challenges.

summary Agent-oriented modelling is one of the simulation methods for emergent behavior of a complex system that could be considered for application of urban city structures. Using advanced script techniques, the behavior and evolution of structures in the bottom-up strategies for the development of environment could be simulated in architecture and urbanism as well. The paper presents a research subproject in the area of verifi cation of the processes of spatial and social interaction of the agents according to the logic of defined intrinsic rules of Swarm behavior in the simulation model of the selected area. The research builds mainly upon two selected requirements of the bottom-up strategy: the approach distances to places of interest and mutual standoff distances between urban elements.

The material expression of these settings provides an important link between: the formal conceptualization, the digital geometric operation, its manufacturing and responsive review, similar to the design process used. At the same time reveals limitations of scale, materiality and design limitations, which condition the models implemented.

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 Gridshells are highly efficient, lightweight structures which can span long distances with minimal use of material (Vassallo & Malek 2017). One of the most promising and novel categories of gridshells are bending-active (elastic) systems (Lienhard & Gengnagel 2018), which are composed of flexible members (Kuijenhoven & Hoogenboom 2012). Timber elastic gridshells can be site-sprung or sequentially erected (geodesic). While a lot of research focus is on the site-sprung ones, the methods for design of sequentially-erected geodesic gridshells remained underdeveloped (Cichocka 2020). The main objective of the paper is to introduce a method of generating regular geodesic grid patterns on free-form surfaces and to examine its applicability to design structurally feasible geodesic gridshells. We adopted differential geometry methods of generating regular bidirectional geodesic grids on free-form surfaces. Then, we compared the structural performance of the regular and the irregular grids of the same density on three free-form surfaces. The proposed method successfully produces the regular geodesic grid patterns on the free-form surfaces with varying curvature-richness. Our analysis shows that gridshells with regular grid configurations perform structurally better than those with irregular patterns. We conclude that the presented method can be readily used and can expand possibilities of application of geodesic gridshells.
