summary The research presented in this paper is part of a larger body of emerging research into embedding autonomy in the built environment. We develop a framework for designing and implementing effective autonomous architecture defined by three key properties: situated and embodied agency, facilitated variation, and intelligence.We present a novel application of Deep Reinforcement Learning to learn adaptable behaviours related to autonomous mobility, self-structuring, self-balancing, and spatial reconfiguration. Architectural robotic prototypes are physically developed with principles of embodied agency and facilitated variation. Physical properties and degrees of freedom are applied as constraints in a simulated physics-based environment where our simulation models are trained to achieve multiple objectives in changing environments. This holistic and generalizable approach to aligning deep reinforcement learning with physically reconfigurable robotic assembly systems takes into account both computational design and physical fabrication. Autonomous Robotic Tensegrity (ART) is presented as an extended case study project for developing our methodology. Our computational design system is developed in Unity3D with simulated multi-physics and deep reinforcement learning using Unity’s ML-agents framework. Topological rules of tensegrity are applied to develop assemblies with actuated tensile members. Single units and assemblies are trained for a series of policies using reinforcement learning in single-agent and multi-agent setups. Physical robotic prototypes are built and actuated to test simulated results.

title Biomimetic Reciprocal Frames - A design investigation on bird's nests and spatial structures

summary Reciprocal Frame (RF) is a constructive system typically applied with timber, since it is composed by discrete elements with short dimensions. It allows the construction of large spans and complex geometries. This kind of structure has been addressed by recent research projects that aim to produce it using computational tools and digital fabrication techniques. Moreover, the enhancement of these technologies enabled the integration of simulations of biological processes into the design process as a way to obtain better and optimal results, which is known as Biomimetics. This paper describes the development of a spatial structure that combines the principles of RF and the assembly process of natural agents, such as birds, in a digital environment. The tools used for the generation of the structure were Rhinoceros, Grasshopper and different add-ons, such as Culebra, Kangaroo, Pufferfish and Weaverbird.

summary By investigating methods for using computation and digital manufacturing technologies to integrate material properties with architectural design tools, the research in this paper aims at revealing new potentials for the use of wood in architecture. Through an explorative approach, material particularities and fabrication methods are explored and combined into new workflows and architectural expressions. The research looks into different properties and capacities of wood, but the main part of the experimentation revolves around crooked oak logs. Due to their irregularities, these logs are normally discarded. However, through the methods suggested in this research, they are instead matched with unique processing informed by their divergence. The research presents a workflow for handling the discrete shapes of sawlogs in a system that both involve the collecting of material, scanning/digitization, handling of a stockpile, computer analysis, design, and robotic manufacturing. The workflow includes multiple custom-made solutions for handling the complex and different shapes and data of wood logs in a highly digitized machining and fabrication environment. The suggested method is established through investigations of wood as a natural material, studies of the production lines in the current wood industry, and experimentation in our in-house laboratory facilities. This up-cycling of discarded wood supply establishes a non-standard workflow that utilizes non-standard material stock and leads to a critical articulation of today’s linear material economy. The research thereby gives an example of how the natural forms and properties of sawlogs can be directly used to generate new structures and spatial conditions.

title Semi-flexible Additive Manufacturing Materials for Modularization Purposes - A modular assembly proposal for a foam edge-based spatial framework

summary This paper introduces a series of design and fabrication tests directed towards the use of bendable 3D printing materials in order to simplify a foam bubble-based geometry as a frame structure for modular assembly. The aspiration to reference a spittlebug's bubble cocoon in nature for a light installation in the urban context was integrated into a computational workflow conditioning light-weight, material-, and cost savings along with assembly-simplicity. Firstly, before elaborating on the project motivation and background in foam structures and applications of 3D-printed thermoplastic polyurethane (TPU) material, this paper describes the physical nature of bubble foams in its relevant aspects. Subsequently this is implemented into the parametric design process for an optimized foam structure with Grasshopper clarifying the need for flexible materials to enhance modular feasibility. Following, the additive manufacturing iterations of the digitally designed node components with TPU are presented and evaluated. Finally, after the test assembly of both components is depicted, this paper assesses the divergence between natural foams and the case study structure with respect to self-organizing behavior.

title Ashen Cabin
source ACADIA 2020: Distributed Proximities / Volume II: Projects [Proceedings of the 40th Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-95253-6]. Online and Global. 24-30 October 2020. edited by M. Yablonina, A. Marcus, S. Doyle, M. del Campo, V. Ago, B. Slocum. 176-181
summary Ashen Cabin, designed by HANNAH, is a small building 3D-printed from concrete and clothed in a robotically fabricated envelope made of irregular ash wood logs. From the ground up, digital design and fabrication technologies are intrinsic to the making of this architectural prototype, facilitating fundamentally new material methods, tectonic articulations, forms of construction, and architectural design languages. Ashen Cabin challenges preconceived notions about material standards in wood. The cabin utilizes wood infested by the Emerald Ash Borer (EAB) for its envelope, which, unfortunately, is widely considered as ‘waste’. At present, the invasive EAB threatens to eradicate most of the 8.7 billion ash trees in North America (USDA, 2019). Due to their challenging geometries, most infested ash trees cannot be processed by regular sawmills and are therefore regarded as unsuitable for construction. Infested and dying ash trees form an enormous and untapped material resource for sustainable wood construction. By implementing high precision 3D scanning and robotic fabrication, the project upcycles Emerald-Ash-Borer-infested ‘waste wood’ into an abundantly available, affordable, and morbidly sustainable building material for the Anthropocene. Using a KUKA KR200/2 with a custom 5hp band saw end effector at the Cornell Robotic Construction Laboratory (RCL), the research team can saw irregular tree logs into naturally curved boards of various and varying thicknesses. The boards are arrayed into interlocking SIP façade panels, and by adjusting the thickness of the bandsaw cut, the robotically carved timber boards can be assembled as complex single curvature surfaces or double-curvature surfaces. The undulating wooden surfaces accentuate the building’s program and yet remain reminiscent of the natural log geometry which they are derived from. The curvature of the wood is strategically deployed to highlight moments of architectural importance such as windows, entrances, roofs, canopies, or provide additional programmatic opportunities such as integrated shelving, desk space, or storage.

summary Tradition wood tectonics, like interlocking joints, have regained focus against the background of digital design and fabrication technologies. While research on interlocking joints is quite focused on joint geometries, especially for timber plates, there has been less attention on the design and mass customization of interlocking joints for linear timber elements. In this context, this research addresses the challenges of mass customization of interlocking joints for linear elements through the design and realization of a 9-meterhigh timber structure with fully interlocking joints, without the use of any nails or glue. A customized code generation program was developed for the fabrication process, allowing the rapid programming and fabrication for all the 840 elements and 2592 notches. The project demonstrates how innovative structures are allowed through the synthesis of joint geometry, assembly process, and cutting-edge fabrication technology.

title Catenary Wooden Roof Structures: Precedent knowledge for future algorithmic design and construction optimisation
doi https://doi.org/10.52842/conf.ecaade.2023.1.611
source Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 611–620
summary The timber industry is expanding, including construction wood product applications such as glue-laminated wood products (R. Sikkema et al., 2023). To boost further utilisation of engineered wood products in architecture, further development and optimisation of related tectonic systems is required. Integration of digital design technologies in this endeavour presents opportunities for a more performative and spatially diverse architecture production, even in construction contexts typified by limited means and/or resources. This paper reports on historic precedent case study research that informs an ongoing larger study focussing on novel algorithmic methods for the design and production of lightweight, large-span, catenary glulam roof structures. Given their structural operation in full tension, catenary-based roof structures substantially reduce material needs when compared with those relying on straight beams (Wong and Crolla, 2019). Yet, the manufacture of their non-standard geometries typically requires costly bespoke hardware setups, having resulted in recent projects trending away from the more spatially engaging geometric experiments of the second half of the 20th century. The study hypothesis that the evolutionary design optimisation of this tectonic system has the potential to re-open and expand its practically available design solution space. This paper covers the review of a range of built projects employing catenary glulam roof system, starting from seminal historic precedents like the Festival Hall for the Swiss National Exhibition EXPO 1964 (A. Lozeron, Swiss, 1964) and the Wilkhahn Pavilions (Frei Otto, Germany, 1987), to contemporary examples, including the Grandview Heights Aquatic Centre (HCMA Architecture + Design, Canada, 2016). It analysis their structural concept, geometric and spatial complexity, fabrication and assembly protocols, applied construction detailing solutions, and more, with as aim to identify methods, tools, techniques, and construction details that can be taken forward in future research aimed at minimising construction complexity. Findings from this precedent study form the basis for the evolutionary-algorithmic design and construction method development that is part of the larger study. By expanding the tectonic system’s practically applicable architecture design solution space and facilitating architects’ access to a low-tech producible, spatially versatile, lightweight, eco-friendly, wooden roof structure typology, this study contributes to environmentally sustainable building.

title Stressed Skin Wood Surface Structure
doi https://doi.org/10.52842/conf.acadia.2019.470
source ACADIA 19:UBIQUITY AND AUTONOMY [Proceedings of the 39th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-59179-7] (The University of Texas at Austin School of Architecture, Austin, Texas 21-26 October, 2019) pp. 470-477
summary Innovation in parametric design and robotic fabrication is in reciprocal relationship with the investigation of new structural types that facilitated by this technology. The stressed skin structure has historically been used to create lightweight curved structures, mainly in engineering applications such as naval vessels, aircraft, and space shuttles. Stressed skin structures were first referred to by Fairbairn in 1849. In England, the first use of the structure was in the Mosquito night bomber of World War II. In the United States, stressed skin structures were used at the same time, when the Wright Patterson Air Force Base designed and fabricated the Vultee BT-15 fuselage using fiberglass-reinforced polyester as the face material and both glass-fabric honeycomb and balsa wood core. With the renewed interest in wood as a structural building material, due to its sustainable characteristics, new potentials for the use of stressed skin structures made from wood on building scales are emerging. The authors present a material informed system that is characterized by its adaptability to freeform curvature on exterior surfaces. A stressed skin system can employ thinner materials that can be bent in their elastic bending range and then fixed into place, leading to the ability to be architecturally malleable, structurally highly efficient, as well as easily buildable. The interstitial space can also be used for services. Advanced digital fabrication and robotic manufacturing methods further enhance this capability by enabling precisely fabricated tolerances and embedded assembly instructions; these are essential to fabricate complex, multi-component forms. Through a prototypical installation, the authors demonstrate and discuss the technology of the stressed skin structure in wood considering current digital design and fabrication technologies.

summary We present a framework to generate intelligent spatial assemblies from sets of digitally encoded spatial parts designed by the architect with embedded principles of prefabrication, assembly awareness, and reconfigurability. The methodology includes a bespoke constraint-solving algorithm for autonomously assembling 3D geometries into larger spatial compositions for the built environment. A series of graph-based analysis methods are applied to each assembly to extract performance metrics related to architectural space-making goals, including structural stability, material density, spatial segmentation, connectivity, and spatial distribution. Together with the constraint-based assembly algorithm and analysis methods, we have integrated a novel application of deep reinforcement (RL) learning for training the models to improve at matching the multiperformance goals established by the user through self-play. RL is applied to improve the selection and sequencing of parts while considering local and global objectives. The user’s design intent is embedded through the design of partial units of 3D space with embedded fabrication principles and their relational constraints over how they connect to each other and the quantifiable goals to drive the distribution of effective features. The methodology has been developed over three years through three case study projects called ArchiGo (2017–2018), NoMAS (2018–2019), and IRSILA (2019-2020). Each demonstrates the potential for buildings with reconfigurable and adaptive life cycles.

summary Virgin materials used in the construction industry strain resources and cause further exploitation. This is true of the raw materials used to produce construction materials and products and the fossil fuels that feed energy into the processing line. The cement industry causes 9% of carbon emissions due to the chemical process of its creation and the energy needed to fuel it (World Green Building Council 2019). To mitigate these impacts, it is imperative to minimize the use of new concrete. This remains a challenge as the demand for construction is high, and simultaneously, buildings no longer deemed fit to use are being demolished and replaced by new construction. Demolished structures are a quarry for new construction. Substantial amounts of rubble from demolitions are crushed in landfills for aggregate. This work leverages the material's larger and stronger form rather than reducing it to infill. Concrete rubble, as chunks, is often considered a complex material to construct with, as it is inconsistent and irregular in size and form. However, better reuse is within reach with the aid of scanning tools, digital design workflows, and advanced fabrication methods. This research proposes tractable ways of upcycling concrete from demolition sites to create new, innovative structures and avoid downcycling the material. The paper demonstrates a novel application of algorithmic tools leveraged to support the use of irregular rubble-based inventories as structural components. The proposed ‘rubble trusses’ are designed as assemblies of concrete chunks that are processed, strung together like a jewelry piece to create a structural and aesthetic language for material circularity as the ‘Crown Jewels’; whereby rubble is regarded as gem.

summary This paper challenges digital preoccupations with precision and control and questions the status of tolerance, allowance and error in post-digital, human-centred architectural production. It uses the participatory action research design-and-build project TOROO, a light-weight bending-active bamboo shell structure, built in Hsinchu, Taiwan, in June 2019, as a demonstrator project to discuss how protean digital design diagrams, named 'vibrant objectiles,' are capable of productively absorbing serendipity throughout project crystallisation processes, increasing designer agency in challenging construction contexts with high degrees of unpredictability. The demonstrator project is then used to discuss future research directions that were exposed by the project. Finally, the applicability of working with 'vibrant objectiles' is discussed beyond its local project use. Common characteristics and requirements are extracted, highlighting project setup preconditions for which the scope covered by the architect needs to be both broadened and relaxed to allow for feedback from design implementation phases.

summary This paper is a description of a hybridized digital and analog workflow for reusing waste corrugated cardboard as a building material. The work explores a combination of digital design and analog fabrication tools to create a workflow that would help designers/builders to negotiate with the material variability of waste cardboard. The workflow discussed here was implemented for designing and fabricating a prototypical modular floor panel using different sheets of waste cardboard combined with repurposed wood. The implementation shows that combining digital and analog tools can create a novel approach to material reuse, and facilitate a design/fabrication culture of smart reuse that supports informal building and making at recycling collection centers in developing countries for housing alternatives

summary The paper presents research for wind-responsive architecture. The main objective is the digital design methodology incorporating the dynamic, fluctuating wind flow into the shape-generating process of architectural envelopes. These computational studies are advanced and informed through physical prototyping models, allowing a hybrid method approach. The negative impacts of the wind at the building scale (wind loads), as well as urban scale (wind discomfort), can be avoided and even transformed into an advantage by incorporating the local wind conditions to the process of creating architectural envelopes with adaptive structures. The paper proposes a tensegrity-membrane system which, when exposed to the dynamic wind flow, enables a local passive shape adaptation. Thus, the action of the wind pressure transforms the shape of the building envelope to an unsmoothed, dimpled surface. As a consequence, the aerodynamic properties of the building are modified, which contributes to reducing wind suction and drag force. Moreover, the slight shape change materializes and articulates the immaterial wind phenomena. For a better understanding of the dynamic geometric properties, one unit of the wind-responsive envelope is tested through simulations, and through physical prototypes. The idea and material-geometric studies are subsequently applied in a specific case study, including a designed building envelope in an industrial silo cluster in Stockholm.

title Design of a post-disaster shelter through soft computing
source International Journal of Architectural Computing vol. 17 - no. 2, 185-205
summary Temporary shelters become a more critical subject of architectural design as the increasing number of natural disasters taking place each year result in a larger number of people in need of urgent sheltering. Therefore, this project focuses on designing a temporary living space that can respond to the needs of different post-disaster scenarios and form a modular system through differentiation of units. When designing temporary shelters, it is a necessity to deal with the provision of materials, low-cost production and the time limit in the emergency as well as the needs of the users and the experiential quality of the space. Although computational approaches might lead to much more efficient and resilient design solutions, they have been utilized in very few examples. For that reason and due to their suitability to work with architectural design problems, soft computing methods shape the core of the methodology of the study. Initially, a digital model is generated through a set of rules that define a growth algorithm. Then, Multi-Objective Genetic Algorithms alter this growth algorithm while evaluating different configurations through the objective functions constructed within a Fuzzy Neural Tree. The struggle to represent design goals in the form of Fuzzy Neural Tree holds potential for the further use of it for architectural design problems centred on resilience. Resilience in this context is defined as a measure of how agile a design is when dealing with a major sheltering need in a post-disaster environment. Different from the previous studies, this article aims to focus on the design of a temporary shelter that can respond to different user types and disaster scenarios through mass customization, using Fuzzy Neural Tree as a novel approach. While serving as a temporary space, the design outcomes are expected to create a more neighbourhood-like pattern with a stronger sense of community for the users compared to the previous examples.

title Actuated Textile Hybrids - Textile smocking for designing dynamic force equilibria in membrane structures

summary This paper introduces Actuated Textile Hybrids, and describes the steps needed to steer the form finding processes necessary for their production. The method presented employs an integration of an "activated" instead of a pre-stressed textile membrane to design different stages of force equilibrium within the Hybrid Structure, and to investigate the potentials of ever flexible shaping of tensile elements. The set-up for the Textile Hybrid consists of three main elements which are digitally and physically analysed in their inextricable interdependence in force, form and material. Together, the bending active beam (rod), the textile membrane and an applied pattern which actively shrinks surface areas of the membrane (activation), create the base for the form finding process.With advanced Finite Element Modelling software and the architects resulting ability to engineer responsive building-systems for a dynamic environment, it is essential to rethink the construction methods and the building-material of the classic building envelope. This is to not only develop a smartly engineered sustainable skin but also a boundary object which, due to its adaptation, develops the potential to interconnect with its surrounding to re-establish the relationships between nature, home and inhabitant.

title Tornado Pavilion - Simplexity, almost nothing, but human expanded abilities

summary In the context of the fourth industrial revolution, not all regions have the same access to technology for project development. These technological limitations do not necessarily result in worst projects and, on the contrary, can stimulate creativity and human intervention to overcome these shortcomings. We report here the design of a small pavilion with scarce budget and an ambitious goal to qualify a space through tactical urbanism. We develop the project in a multidisciplinary partnership between academy and industry, designing, manufacturing and assembling Tornado Pavilion, a complex structure using combined HIGH-LOW technologies, combining visual programming with analog manufacture and assembly. The design strategy uses SIMPLEXITY with ruled surfaces strategy to achieve a complex geometry. Due to the lack of automated mechanical cutting or assembly, we used human expanded abilities for the construction; instead of a swarm of robots, we had a motivated and synchronized swarm of students. The pavilion became a reference for local population that adopted it. This process thus shows that less or almost nothing (Sola-Morales 1995), need not to be boring (Venturi 1966) but less can be much more (Kolarevic 2017).

summary Current computer-aided-design tools tend to focus on technical descriptions of objects and processes, while disregarding the agency of the designer in the creative process. This research shifts the focus to explore how computational tools could embrace the designer’s perception and trigger design exploration. In this direction, Pattern Mapping is presented as a prototypical software for the designing, making, and learning of a geometric material system: free-form surfaces created by the deformation of thin aluminum with auxetic-pattern slits. Along with the development of the software, the paper reports on a new methodology towards visual exploration in computational tools. Texture mapping—a computer-graphics algorithm—is utilized to bridge intuitive visualizations of form and materiality with geometric analysis. Informed by recent studies on design creativity, visual perception, and a precedent of an artist’s workflow, the proposed software facilitates learning through multiple modes of representations and drawing-like operations. Ultimately, Pattern Mapping is a provocation for the fusion of computational analysis with perception, drawing, and making.

summary A workflow for integration of parametric modeling with BIM, using generative-programming, is described and tested in this research. The objective is to take advantage of these two distinctive design paradigms. This paper describes a design experiment that required a NURBS roof generated by sweeping profiles along a curved path. We assumed the use of multiple applications, using various file formats, are facts and are unlikely to disappear. Given that interoperability issues will certainly arise, we propose and test a design workflow using parametric modeling, generative programming, and building information modeling. Our major contribution was defining a workflow for designing NURBS surfaces and corresponding supporting structures enhancing interoperability among different applications through generative-programming.

title Interoperability Workflow Method for Designing NURBS Surfaces and Structures with Generative Programming
source Ji-Hyun Lee (Eds.) "Hello, Culture!"  [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, pp. 88-100
summary The workflow for integration of parametric modeling with BIM is using generative-programming described and tested in this research. The workflow aims to take advantage of these two distinctive design paradigms. This paper describes a design experiment that called for a NURBS roof generated by sweeping profiles along a curved path. Computer applications in the field of architecture are often based on a diverse range of design paradigms. We assumed the use of multiple applications, using various file formats, are facts and are unlikely to disappear. Given that interoperability issues will certainly arise, in this article, we propose and test a design workflow using parametric modeling, generative programming, and building information modeling. Our objective is to test the efficiency and improve upon the compatibility between Parametric-Algorithmic-Design and BIM applications. Our major contribution was defining a workflow for designing NURBS surfaces and corresponding supporting structures enhancing interoperability among different applications through generative-programming.

title Designing for Shape Change - A Case study on 3D Printing Composite Materials for Responsive Architectures
doi https://doi.org/10.52842/conf.caadria.2019.2.391
source M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 2, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 391-400
summary This paper presents the initial stages of a research that aims to develop hydroactive architectural skin systems that respond to environmental humidity. As part of this study, we have developed wood-based bio-composite materials that are 3D printed with wood filament. Shape-changing behavior is not predictable in advance. We developed customized 3D printing protocols to systematically study shape-changing behavior. The paper presents this systematic material study and the prototypes that we have developed.
