title	TEC-House: Itinerant Modular Space Based on Digital Fabrication
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1499–1510
summary	The academy aims to understand and insert digital technologies in the collaborative, interdisciplinary and innovative process. Thus, the process of this project aims to develop an itinerant space that enables integration between academics and the community, associated with digital technologies, making it essential as a precursor of knowledge, innovation and social well-being. Based on concepts from Smart City and Smart Campus, as it addresses a phenomenon of development intrinsic to technological processes in pursuit of environmental quality, it appropriates of digital manufacturing tools as a programmatic production model. Inspired by the generation of physical objects from digital models along the lines of Wikihouse, a modular architectural executive method was developed as an alternative for flexibility and movement. At the end of the process, there is the conception of the TEC-House, idealized as an itinerant modular space, based on anthropometric parameters where function determines the way they integrate, constituting modifying places.

title	Computational design and fabrication of highly customizable architectural space frames: Making a flat-cut Weaire-Phelan structure
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 1, 37–49
summary	This paper documents a computational approach to the design, fabrication, and assembly of customizable space structures built entirely out of flat-cut interlocking elements without the need of nodes, fasteners, cement, or glue. Following a Research by Design (RbD) methodology, we establish a framework comprising geometric and parametric modeling, structural analysis, and digital fabrication stages to examine the following research question: how might the modularity of a construction kit be combined with the plasticity of parametric descriptions to facilitate the design and fabrication of flat-cut space structures? We find that an adaptive joint design that resolves local deformations at the node and element levels can facilitate the construction of flat-cut space structures by making modular components responsive to local geometric, material, and mechanical demands. The research centers on the design and construction of an architecture-scale installation based on the Weaire-Phelan structure—an aperiodic space-filling geometric structure that approximates the geometry of foam—entirely out of flat-cut interlocking elements. Documenting the process in technical detail, as well as some limitations, the paper contributes to recent efforts to develop digital materials suitable for architectural applications. In addition, it contributes to extend the formal and architectural possibilities of flat-cut space structure design by facilitating “bottom-up” design explorations in concert with the structure’s tectonic resolution.

summary	The circumstances of the pandemic resulted in the closure of collective maker spaces and university fab labs. This disruption to machine access had consequences for design studio curricula which shifted to online and digital formats. In response, an experimental studio centered on digital fabrication was offered in the Spring of 2021 at MIT. The prompt of the studio was simple, to design and build an installation with spatial implications, wherever and with whatever material was at hand. To support students to re-engage physical making, a desktop milling machine was developed called the TinyZ. Due to its small scale and low cost, the TinyZ could be distributed as a kit to each participant in the studio. The TinyZ Kit was largely composed of standard parts and repetitive assemblies, making the machine itself extremely modular and easily reconfi gurable to adapt to different material processes and projects throughout the semester.

title	Floating Modular Houses as Solution for Rising Sea Levels - A case study in Kiribati island

summary	Many island states, due to rising sea levels, have a problem with losing inhabitant homes. One of those countries is Kiribati island. Nowadays, this problem is solved by applying floating architecture, so life on the land is transferred to the water surface. Building settlements of this type is very complex. This paper proposes a unique concept for architectural and urban design using computational intelligence methods and the principles of regular tessellation. It is necessary to define the architectural program, ie. input data for the design process based on the general and special needs of users in terms of the functional organization of space. Each data will be represented by a module of unique dimensions, and the connections between the data by parameters, which result in a functional Bubble diagram of a modular floating house. By setting the requirements for the minimal perimeter and maximum area, the most optimal design of each of geometric shapes of regular tessellation will be chosen and evaluated by objective and subjective parameters of the design quality to find out which one is the most suitable for the modular floating house and then sustainable floating settlement.

summary	This research demonstrates the development of a hybrid FRP-timber wall and slab system for multi-story structures. Bespoke computational tools and robotic fabrication processes allow for adaptive placement of material according to specific local requirements of the structure thus representing a resource-efficient alternative to established modes of construction. This constitutes a departure from pre-digital, material-intensive building methods, based on isotropic materials towards genuinely digital building systems using lightweight, hybrid composite elements. Design and fabrication methods build upon previous research on lightweight fiber structures conducted at the University of Stuttgart and expand it towards inhabitable, multi-story building systems. Interdisciplinary design collaboration based on reciprocal computational feedback allows for the concurrent consideration of architectural, structural, fabrication and material constraints. The robotic coreless filament winding process only uses minimal, modular formwork and allows for the efficient production of morphologically differentiated building components. The research results were demonstrated through Maison Fibre, developed for the 17th Architecture Biennale in Venice. Situated at the Venice Arsenale, the installation is composed of 30 plate like elements and depicts a modular, further extensible scheme. While this first implementation of a hybrid multi-story building system relies on established glass and carbon fiber composites, the methods can be extended towards a wider range of materials ranging from ultra-high-performance mineral fiber systems to renewable natural fibers.

summary	The circumstances of the pandemic have resulted in the closure of workshops and Fab Labs and put physical making on hold for fabrication-based design courses. However, with digital fabrication having become a crucial component of design education, involving the critical transition from design ideas represented digitally to being realized physically, alternative approaches needed to be found. Remote making can be enabled by the potentials of small-scale modular machines, which due to their low cost, are easily distributable and can be shipped to each student in a design studio. The use of at-home fabrication offers new possibilities for project-adaptive prototyping tools. Desktop scaled fabrication tools designed to reach a distributed audience abound in industry, academia, and amongst DIY-ers. Drawing from these precedents, a desktop milling machine called the TinyZ was developed to support digital fabrication in an architectural studio held at MIT in the Spring of 2021. The machine was designed to be an easily reconfigurable rapid prototyping tool intended to adapt to evolving design processes. The TinyZ Kit introduced students to the basics of machine building, electronics, and computer numerically controlled (CNC) programming. The outcome of the studio showed the potential for different home labs to develop specializations and to collaborate by out-sourcing, offering a way for students to work together remotely. Finally, the work of the studio demonstrated that new material processes developed remotely could return to fab labs and extend the capacities of shared maker spaces.

title	An Immersive Modular Museum-Archive Concept Model - An integration of shape grammars with virtual reality
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 323-332
doi	https://doi.org/10.52842/conf.ecaade.2021.2.323
summary	The paper presents a concept model of a modular exhibition that is designed to function as a museum in the physical environment and as an archive of architectural projects in the virtual. A design method based on shape grammars and inspired by the Bauhaus teaching, has been used to generate both the museum spaces and the archive which expands endlessly as the acquisition of architectural exhibits keeps increasing. Specifically, rules that control the geometric organization, tectonic expression and linear or radial expansion of a modular assembly of interlocking physical or virtual spaces, leading to various self-similar spatial patterns, have been developed. Several scenarios of the visitors' interaction with the exhibits and the museum's space with the use of VR and AR have been explored. In the actual museum scenario, physically present visitors can interact with the exhibits which are enriched with digital information. In the case of the archive, the Unity platform is used for the development of a virtual experience of the visitor who interacts with the expanding space and exhibits in a purely immersive manner.

summary	This paper will propose the integration of multi-view stereo and time of flight technologies and components. Through the spatial point cloud sensor, the changes of objects in the space are converted into digital point clouds, which are feedback on the virtual interface. To make the virtual and physical will continuously communicate and feedback in space, which we established a correction tool for the integration of virtual and physical. The agent-based sensor computing method combines the fabrication process of visual sensors and behavior, from virtual object control to fabrication machines. In this tool, users can explain the reasons for design decisions by visualizing process and process-related information. It allows virtual and physical previews and feedback in real time, and finds out the differences between the two and makes real-time corrections. Solved the correction problem of coexistence.

title	JointSearch: Efficient parametric detailing preparation through user-defined and property-based joint type filtering
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 3, 386–400
summary	Detailing joints are important when designing structures. In this design process, a structure is divided into different joint types. Digital fabrication and algorithmic aided design have changed the conceptions and requirements of joint detailing. However, parametric tools that can efficiently identify joint types based on the solution space are not available. This article presents a methodology that efficiently generates topological relations and enables the user to assign joint instances to joint types. A series of property-based search criteria components is applied to define the solution space of a joint type. Valid joints are coherently filtered, deconstructed and outputted for detailing. The article explains both the methodology and programming-related aspects of the joint type filtering. The article concludes that the developed methodology offers the desired flexibility and may be suitable for other materials and applications.

summary	Graphic statics vividly shows the topological relationship between the "form" represented by the structure itself and the "force" generated by its action through graphic method, which has become an important tool for architects to carry out structural innovative design in the past century. In the 21st century, with the development of computer technology, graphic statics has developed from the dual relationship between 2D thrust network and closed force polygon to the dual relationship between 3D thrust network and space closed force polyhedron. In this paper, the design method of graphic statics based on 3D graphic statics is applied to a stainless chair and an ice pavilion design. Researchers used different digital fabrication methods to manufacture the chair and the pavilion according to its material attribute.

title	The Use of Diagrammatic Reasoning to Aid Conceptual Design in Building Information Modeling (BIM)
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 39-48
doi	https://doi.org/10.52842/conf.ecaade.2021.2.039
summary	Architectural design is an intellectual activity where the architect moves from the abstract to the real. In this process, the abstract represents the logical reasoning of how architectural form is configured or structured, while the real refers to the final physical form. Diagrams become an integral part of the conceptual design stage because they mediate between those two realms. Building Information Modeling (BIM) can reallocate the effort and time to emphasize conceptual design. However, many consider BIM a professionally-oriented tool that is less suitable for the early design stages. This research suggests that architectural design reasoning can be achieved using constraint-based parametric diagrams to aid conceptual design in BIM. The study examines several techniques and constructs a framework to use diagrams in the early design stages. This framework has been investigated through Villa Stein and Citrohan House by Le Corbusier. This study addresses two roles of diagrams: the generative role to create various design solutions and the analytical one to conduct an early performance study of the building. Our research contributes to the discussion on the ways designers can use digital diagrams to support the architectural design process.

title	A Chained Machine Learning Approach to Motivate Retro-Cladding of Residential Buildings

doi	https://doi.org/10.52842/conf.ecaade.2021.1.055
summary	This paper investigates how a novel approach to visualisation could help address the challenge of motivating residential retrofitting. Emerging retrofitting research and practice emphasises retro-cladding - the upgrading of the exterior facade of a building - using a modular approach. We present a machine-learning based approach aimed to motivate residential retrofitting through the generation of images and cost/benefit information describing climatically specific additions of external insulation and green roof panels to the façade of a Danish type house. Our approach chains a series of different models together, and implements a method for the controlled navigation of the principle generative styleGAN model. The approach is at a prototypical stage that implements a full workflow but does not include numerical evaluation of model predictions. Our paper details our processes and considerations for the generation of new datasets, the specification and chaining of models, and the linking of climatic data to travel through the latent space of a styleGAN model to visualise and provide a simple cost benefit report for retro-cladding specific to the local climates of five different Danish cities.

summary	The paper describes the findings of the applied research project by Institute Integrative Design (currently ICDP) HGK FHNW and ERNE AG Holzbau to design and manufacture prefabricated wooden façades in the collaborative design manner between architects and industry. As such, it is an attempt to respond to the current interdisciplinary split in the construction, which blocks innovation and promotes standardized inefficient building solutions. Within this project, we apply three innovations in the industrial setup that result in the integrated design-to-production process of individualized, cost-efficient and well-crafted façades. The collaborative design approach is a method in which architect, engineer and manufacturer start exchange on the early stage of the project during the collaborative design workshops. Digital design and fabrication tools enable architects to generate a large scope of façade variations within production feasibility of the manufacturer and engineers to prepare files for robotic production. Novel multi-robot fabrication processes, developed with the industrial partner, allows for complex façade assembly. This paper introduces the concept of digital craftsmanship, manifested in a mixed fabrication system, which intelligently combines automated and manual production to obtain economic feasibility and highest aesthetic quality. Finally, we describe the design and fabrication of the project demonstrator consisting of four intricate façades on a modular office building, inspired by local traditional solutions, which validate the developed methods and highlight the architectural potential of the presented approach.

title	GoDesign - A modular generative design framework for mass-customization and optimization in architectural design

doi	https://doi.org/10.52842/conf.ecaade.2021.1.285
summary	We present a modular generative design framework for design processes in the built environment that provides for the unification of participatory design and optimization to achieve mass-customization and evidence-based design. The paper articulates this framework mathematically as three meta procedures framing the typical design problems as multi-dimensional, multi-criteria, multi-actor, and multi-value decision-making problems: 1) space-planning, 2) configuring, and 3) shaping; structured as to the abstraction hierarchy of the chain of decisions in design processes. These formulations allow for applying various problem-solving approaches ranging from mathematical derivation & artificial intelligence to gamified play & score mechanisms and grammatical exploration. The paper presents a general schema of the framework; elaborates on the mathematical formulation of its meta procedures; presents a spectrum of approaches for navigating solution spaces; discusses the specifics of spatial simulations for ex-ante evaluation of design alternatives. The ultimate contribution of this paper is laying the foundation of comprehensive Spatial Decision Support Systems (SDSS) for built environment design processes.

summary	This paper focuses on the woven textiles of Otavalo, Ecuador, as a case study for improved cultural representation in architectural design. A shape grammar methodology is used to identify specific geometry and elucidate relationship rules found in existing artifacts. These geometry and relationships are subsequently used to produce patterns; both replicas of traditional tapestries as well as new configurations. Extending from 2D to 3D and from digital to physical, sets of modular prototypes are developed based on patterns produced using the defined Otavalo Textile Grammar. Model parts are supplied to study participants; new building blocks for architecture as a spatial and social undertaking.

doi	https://doi.org/10.52842/conf.caadria.2021.1.603
summary	This paper presents the design and fabrication of a lightweight composite facade shading panel using 3D printing (3DP) of mineral foams. Albeit their important role in industrial construction practice as insulators and lightweight materials, only little research has been conducted to use foams in 3DP. However, the recent development of highly porous mineral foams that are very suitable for extrusion printing opens a new chapter for development of geometrically complex lightweight building components with efficient formwork-free additive manufacturing processes. The work documented in this paper was based on preliminary material and fabrication development of a larger research endeavor and systematically explored designs for small interlocking foam modules. Furthermore, the robotic 3D Printing setup and subsequent processing parameters were tested in detail. Through extensive prototyping, the design space of a final demonstrator shading panel was mapped and refined. The design and fabrication process is documented and shows the potential of the novel material system in combination with fiber-reinforced ultra-high performance concrete (UHPC). The resulting composite shading panel highlights the benefits of using mineral foam 3DP to fabricate freeform stay-in-place formwork for lightweight facade applications. Furthermore, this paper discusses the challenges and limitations encountered during the project and gives a conclusive outlook for future research.

title	Quantification of Effective Temporal Exposure to Daylight Illuminance Levels in Healthcare Settings
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 315–326
summary	The purpose of this study is the quantification of the exposure of occupants to daylight illuminance levels. The case study is the typical floor of a patient tower occupied by nurses in twelve hours shifts, from 7 am to 7 pm. Significant evidence exists regarding the positive impact of access to daylight on staff outcomes in healthcare facilities in terms of reduction of stress, absenteeism, medication errors, and burn outs. However, the standard daylight simulation methods evaluate the building and do not capture the dynamic nature of people’s behavior while moving through the space. The proposed approach combines agent-based simulation and daylight performance analysis to compute the occupants’ exposure to daylight levels throughout the year. The results show the discrepancies between building-centric and human-centric types of analysis and the contribution of dynamic simulation methods to design occupancy schedules to warranty equitable access to daylight to building occupants.

summary	The purpose of this experience consisted of linking two methodologies usually used exclusively in the study of the design operation in the university academic environment: working with cardboard models and augmented reality. The methodology used consisted of work in groups based on skills to build cardboard models, to model in 3D, and to work with augmented reality. They developed interior space designs through the interaction of physical models (made of cardboard) and observed models on those physical models through systems equipped with applications to view augmented reality. Among the main results of this experience are the possibility of interacting with dynamic objects modeled in 3D in the physical field of the cardboard model, and the successful integration of two work methodologies (analog and digital), at least in one of the stages of the design operation.

title	Ilustremos: UX+XR and Parametric Design for MUVEs
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 451–462
summary	In the midst of a global pandemic crisis, this proposal seeks to solve a need for a synchronous and multi-user interactive virtual environment for the exhibition of artworks as part of an international illustrators encounter. This research shows a UX+XR design strategy based on UX methodology and the inclusion of parametric design for MUVEs that is framed in a UX+XR prototype for the exhibition, virtual-meeting place, and pedagogical experiential approach directed to defined users. The result, a virtual space named “Ilustremos” (let's illustrate) is created to promote creativity, celebrate art, create community and multidisciplinary collaboration.
