title	Spatial Nets: the Computational and Material Study of Reticular Geometries

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.

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	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.

title	On-site Robotic Assembly of Double-curved Self-supporting Structures
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 746-753.
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	Anisoptera; Anisopteran Deformation and the Latent Geometric Patterns of Wood Envelopes
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
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.

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	In 2015, an earthquake of 7.8 magnitude displaced over 6.6 million people in Kathmandu, Nepal. Three years later, the country continues in its struggle to rebuild its capital. The aim of this study is to investigate a construction system, produced from locally sourced materials, that can aggregate and deploy as self-built, habitable infrastructure. The study focused on the relationship between material resonance, earthquake resistant structures, and fabrication strategies. An agent-based form-finding algorithm was developed using knowledge acquired through physical prototyping of mycelium-based composites to generate earthquake resistant geometries, optimize material usage, and enhance spatial performance. The results show compelling evidence for a construction methodology to design and construct a 3-4 story building that holds a higher degree of resistance to earthquakes. The scope of work contributes to advancements in bioengineering, confirming easy-to-grow, light-weight mycelium-composites as viable structural materials for construction.

summary	The non-standard approach, widely discussed in the past years as Architecture progressively uses alternative design methods different from the Euclidean paradigm, has allowed architects to transform the way architecture is conceived and materialized. Such evolution uses computer-aided design along with automation in production to originate the environment for the aided architectural conception field in which we present a method, in its early development stage, intended to create non-standard walls and envelopes based on cellular patterns using wood as base material. We present the results obtained from modeling and building two full-scale prototypes of non-standard wooden walls.

summary	The construction and building sector is now widely known to be one of the biggest energy consumers, carbon emitters, and creators of waste. Some architectural agendas for sustainability focus on energy efficiency of buildings that minimize their energy intake during their lifetime - through the use of more efficient mechanical systems or more insulative wall systems. One issue with these sustainability models is that they often ignore the hierarchy of energy within architectural design. The focus on the efficiency is but one aspect or system of the building assembly, when compared to the effectiveness of the whole, which often leads to ad-hoc ecology and results in the all too familiar “law of unintended consequences” (Merton, 1936). As soon as adhesive is used to connect two materials, a piece of trash is created. If designers treat material as energy, and want to use energy responsibly, they can prolong the lifetime of building material by designing for disassembly. By changing the nature of the physical relationship between materials, buildings can be reconfigured and repurposed all the while keeping materials out of a landfill. The use of smart joinery to create building assemblies which can be disassembled, has a milieu of new possibilities created through the use of digital manufacturing equipment. These tools afford designers and manufacturers the ability to create individual joints of a variety of types, which perform as well or better than conventional systems. The concept of design for disassembly is a recognizable goal of industrial design and manufacturing, but for Architecture it remains a novel approach. A classic example is Kieran Timberlake's Loblolly House, which employed material assemblies “that are detailed for on-site assembly as well as future disassembly and redeployment” (Flat, Inc, 2008). The use of nearly ubiquitous digital manufacturing tools helps designers create highly functional, precise and effective methods of connection which afford a building to be taken apart and reused or reassembled into alternative configurations or for alternative uses. This paper will survey alternative energy strategies made available through joinery using digital manufacturing and design methods, and will evaluate these strategies in their ability to create diassemblable materials which therefore use less energy - or minimize the entropy of energy over the life-cycle of the material.

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	3D printing as support for arts education for the visually impaired

summary	This article discusses some methodologies in art education in schools and educational activities in museums. It focuses on accessibility and in the visually impaired rights to access and improve the experiences and repertoire in artistic languages, recognizing the use of new technologies in the field of digital manufacturing as valuable resources for the production of teaching materials with the use of cheaper and accessible technology, which expands the access to cultural institutions and education. Considering that most of the museums art works are not to be touched, 3D printing reproductions in durable low cost plastic present as an alternative for tactile experience. In addition, the photogrammetric 3D scanning process and digital editing allow for the creation of isolated parts and materials originated from the art piece, broadening the pedagogical possibilities of art educators. The production of didactic material for arts teaching, with the use of 3D printed copies (edited or not) originated from 3D scans, may help revealing a more subtle and sophisticated aspect of artistic narrative to the public and the visually impaired.

title	Parametric environment for internalization and classification of models generated by the Shap-E tool

summary	Computing has been increasingly employed in design environments, primarily to perform calculations and logical decisions faster than humans could, enabling tasks that would be impossible or too time-consuming to execute manually. Various studies highlight the use of digital tools and technologies in diverse methods, such as parametric modeling and evolutionary algorithms, for exploring and optimizing alternatives in architecture, design, and engineering (Martino, 2015; Fagundes, 2019). Currently, there is a growing emergence of intelligent models that increasingly integrate computers into the design process. Demonstrating great potential for initial ideation, artificial intelligence (AI) models like Shap-E (Nichol et al., 2023) by OpenAI stand out. Although this model falls short of state-of-the-art sample quality, it is among the most efficient orders of magnitude for generating three-dimensional models through AI interfaces, offering practical balance for certain use cases. Thus, aiming to explore this gap, the presented study proposes an innovative design agency framework by employing Shap-E connected with parametric modeling in the design process. The generation tool has shown promising results; through generations of synthetic views conditioned by text captions, its final output is a mesh. However, due to the lack of topological information in models generated by Shap-E, we propose to fill this gap by transferring data to a parametric three-dimensional surface modeling environment. Consequently, this interaction's use aims to enable the transformation of the mesh into quantifiable surfaces, subject to collection and optimization of dimensional data of objects. Moreover, this work seeks to enable the creation of artificial databases through formal categorization of parameterized outputs using the K-means algorithm. For this purpose, the study methodologically orients itself in a four-step exploratory experimental process: (1) creation of models generated by Shap-E in a pressing manner; (2) use of parametric modeling to internalize models into the Grasshopper environment; (3) generation of optimized alternatives using the evolutionary algorithm (Biomorpher); (4) and classification of models using the K-means algorithm. Thus, the presented study proposes, through an environment of internalization and classification of models generated by the Shap-E tool, to contribute to the construction of a new design agency methodology in the decision-making process of design. So far, this research has resulted in the generation and classification of a diverse set of three-dimensional shapes. These shapes are grouped for potential applications in machine learning, in addition to providing insights for the refinement and detailed exploration of forms.

summary	This paper discusses the development of an informed Design-to-Robotic-Production (D2RP) system for additive manufacturing to achieve performative porosity in architecture at various scales. An extended series of experiments on materiality, fabrication and robotics were designed and carried out resulting in the production of a one-to-one scale prototype. In this context, design materiality has been approached from both digital and physical perspectives. At digital materiality level, a customized computational design framework is implemented for form finding of compression only structures combined with a material distribution optimization method. Moreover, the chained connection between parametric design model and robotic production setup has led to a systematic study of certain aspects of physicality that cannot be fully simulated in the digital medium, which then establish a feedback loop for underrating material behaviors and properties. As a result, the D2RP system proposes an alternative method of robotic material deposition to create an informed material architecture.

summary	This paper introduces a counter-mapping attempt augmented by a Geoweb 2.0 platform in the context of two Belgian inner-city neighborhoods. The two aims of this project were to build a platform for the collective construction of a better understanding this dynamic super-diverse arrival environment and bring the various qualities and aspects of these super-diverse urban neighborhoods to foreground. In this study we report on the first results of this project which took place in Ghent and Brussels in 2014. Around 300 architecture students registered, interpreted and geocoded visible signs along preconceived tracks by means of a Geoweb 2.0 platform. Through field observations and interviews, the students created dynamic and interactive maps. We found that the large-scale mapping through Geoweb 2.0 makes it possible to discern different layers of use in arrival neighborhoods. These layers referred to different population groups which continuously have to negotiate each other's presence. Furthermore, the platform created the possibility to effectively and efficiently combine student fieldwork with online and offline lectures and offered students the opportunity to comment on, peer-review and learn from each other's insights. The findings will serve as an alternative information resource in the forthcoming Master's thesis graduation design studio which will be led by the first author.

summary	This paper discusses the potential of a BIM platform for offsite timber construction within the context of the UK construction industry. It examines the benefits, limitations, and challenges that BIM brings for offsite timber. Proof-of-concept projects are presented that deal with the architectural technology, structural engineering, and life cycle analysis aspects. These demonstrate the feasibility of the development of an open BIM platform which would establish a common standard for the industry. The paper concludes by suggesting an alternative business model for offsite timber construction, as enabled by Building Information Modelling.

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.

summary	This study focuses on developing three-dimensional solar panels, as an alternative to traditional flat Photovoltaic (PV) surfaces in Building Integrated Photovoltaic (BIPV). We propose to increase the energy efficiency of buildings by using the entire envelope for energy production as well as by increasing the efficiency of solar energy output in orientations which were traditionally considered as non-ideal. The panels are constructed from Polycarbonate with integrated flexible photovoltaic film, solar paint or dye. The methodology included digital algorithm-based tools for achieving optimized variable three-dimensional surfaces according to local orientation and location, computational climatic simulations and comparative field tests. In addition, the structural, mechanical and thermal properties of the integration between flexible PV sheets and hard plastic curved panels were studied. Interim results demonstrate a potential improvement of 50-80% in energy production per building unit resulting from geometric variations per-se. The dependence of energy production by surface geometry was revealed and an optimized method for solar material distribution on the surface was proposed. A parametric digital tool for automatic generation of optimized three-dimensional panels was developed together with a database and material models of the optimized panels system.

title	Generative Design for Folded Timber Structures

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.
