title	ASCAAD 2023: C+++: Computation, Culture, and Context
source	C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, 1042 p.
summary	The ASCAAD 2023 theme focuses on Computation, Culture, and Context; a triad that is increasingly informing and reshaping the emerging dynamics of design and construction in the built environment of several regions in the Global South. Socio-cultural spheres, heritage roots, contextual relevance, and art and material culture have historically been the primary sources for design and construction innovation and uniqueness in such regions and contexts. Complex geopolitical events however have resulted in a shift towards a perplexed practice of post-modernist styles or imported Western models of design and production, coupled with some attempts to rebrand modernist and post-modernist approaches through critical regionalism and revolts against orientalist movements. Technology and computation have always been an active factor and tool in reflecting these practices. Advancements in computational design have in some ways sparked a latent intent to revive the character and heritage of rich civilizations. While this has led to growing interest within communities belonging to such rich history to adopt computational methodologies and practices, it has equally raised questions regarding authenticity, innovation and identity. Many of the recent attempts to shift away from Western-centered orientalist approaches have in reality not been that far, but have often further accentuated the superficial use of geometrical practices and pattern-based approaches in art, architecture, and urban design, characterized by stereotypical schemes in building interiors, façade screens, and spatial configurations.

summary	InterLoop employs previously developed workflows that enable multi-planar robotic bending of metal tubes with high accuracy and repeatability (Huang and Spaw 2022). The scale and complexity is managed by employing augmented reality (AR) technology in two capacities, fabrication and assembly (Jahn et al. 2018; Jahn, Newnham, and Berg 2022). The AR display overlays part numbers, bending sequences, expected geometry, and robot movements in real time as the robot fabrication is occurring. For assembly purposes, part numbers, centerlines, and their expected positional relationships are projected via quick response (QR) codes spatially tracked by the Microsoft Hololens 2 (Microsoft 2019). This is crucial due to the length and self-similarity of complex multi-planar parts that make them difficult to distinguish and orient correctly. Leveraging augmented reality technology and robotic fabrication uncovers a novel material expression in tubular structures with bundles, knots, and interweaving (Figure 1).

summary	This project explores the advantages of employing continuum material topology optimization in a 3D non-standard lattice structure through fiber additive manufacturing processes (Figure 1). Additive manufacturing (AM) has gained rapid adoption in architecture, engineering, and construction (AEC). However, existing optimization techniques often overlook the mechanical anisotropy of AM processes, resulting in suboptimal structural properties, with a focus on layer-by-layer or planar processes. Materials, processes, and techniques considering anisotropy behavior (Kwon et al. 2018) could enhance structural performance (Xie 2022). Research on 3D printing materials with high anisotropy is limited (Eichenhofer et al. 2017), but it holds potential benefits (Liu et al. 2018). Spatial lattices, such as space frames, maximize structural efficiency by enhancing flexural rigidity and load-bearing capacity using minimal material (Woods et al. 2016). From a structural design perspective, specific non-standard lattice geometries offer great potential for reducing material usage, leading to lightweight load-bearing structures (Shelton 2017). The flexibility and freedom of shape inherent to AM offers the possibility to create aggregated continuous truss-like elements with custom topologies.

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.

summary	Over the past several decades, the conception and construction of formal complexity has disregarded the realities of material waste, costs, and accessibility. By engaging the isometric relationship between flatness and three-dimensional form, the research shown here investigates how waste-conscious approaches to geometric innovation can create new architectural languages. Specifically, the work deploys a subset of curved-crease folding that uses planar reflections referred to as sectional mirror operations to create unique forms comprised of composite cylindrical and conical surfaces (Figure 1). Whereas known studies in curved-crease folding typically explore singular (one-off, figural) compositions (Davis et al. 2013), this process develops a module aggregation strategy to suggest large inhabitable structures as both figural and field-like conditions.

summary	Climate change is not a theoretical construct that might affect future generations; it is happening now. Wildfires, drought, and extreme temperatures are occurring throughout the world, and are projected to get worse. These environmental changes affect all species on this planet. Due to the overwhelming, depressing, and complex subject matter that is climate change, people can feel apathetic or tune out when it is being discussed, in addition to having feelings of hopelessness surrounding the future. These feelings are categorized as eco-anxiety (Ágoston et al. 2022, 1-3).

summary	This practice-based research presents insights into the potential and challenges for augmented and mixed reality (AR/MR) technology to enhance Australian small-to-medium (SME) custom manufacturers’ agility to overcome existing Industry 4.0 (I4.0) workforce productivity and efficiency challenges. Moreover, it seeks to understand the technology’s ability to support custom manufacturers and the architectural, engineering and construction (AEC) sector transition to a more human-centric Industry 5.0 (I5.0) model, whereby the well-being of the fabricator is placed back at the centre of manufacturing processes. This qualitative study draws on interviews with eleven Australian custom manufacturing industry professionals to inform pertinent themes around fabricators’ current use and perceptions of mixed reality technology. Results indicate benefits for fabricators in reducing 2D drawing and task-related ambiguities in fabrication and assembly practices and reveal factors surrounding underutilisation. Synthesising insights and reflecting on Teixeira et al., (2021)’s XR-PACT framework, key research areas are identified for future AR/MR development centred on fabrication users’ distinct needs to improve accessibility, empower fabricators and ultimately assist the competitiveness of custom manufacturers and the AEC sector.

title	Augmented Reality Assisted Robotic: Tube Bending

summary	The intent of this research is to study potential improvements and optimizations in the context of robotic fabrication paired with Augmented Reality (AR), leveraging the technology in the fabrication of the individual part, as well as guiding the larger assembly process. AR applications within the Architecture, Engineering, and Construction (AEC) industry have seen constant research and development as designers, fabricators, and contractors seek methods to reduce errors, minimize waste, and optimize efficiency to lower costs (Chi, Kang, and Wang 2013). Recent advancements have made the technology very accessible and feasible for use in the field, as demonstrated by seminal projects such as the Steampunk Pavilion in Tallinn, Estonia (Jahn, Newnham, and Berg 2022). These types of projects typically improve manual craft processes. They often provide projective guidelines, and make possible complex geometries that would otherwise be painstakingly slow to complete and require decades of artisanal experience (Jahn et al. 2019). Building upon a previously developed robotic tube bending workflow, our research implements a custom AR interface to streamline the bending process for multiple, large, complex parts with many bends, providing a pre-visualization of the expected fabrication process for safety and part-verification purposes. We demonstrate the utility of this AR overlay in the part fabrication setting and in an inadvertent, human-robot, collaborative process when parts push the fabrication method past its limits. The AR technology is also used to facilitate the assembly process of a spatial installation exploring a unique aesthetic with subtle bends, loops, knots, bundles, and weaves utilizing a rigid tube material.

title	Task and Motion Planning for Robotic Assembly
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 3: Proceedings of the 43rd Annual Conference for the Association for Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9891764-1-0].

summary	When programming robotic assembly processes, it is often necessary to create a sequential list of actions. Some actions are robotic motions (requiring motion trajectory), and some are for controlling external equipment, such as grippers and fastening tools. The act of planning these actions and motion trajectories is called Task Planning and Motion Planning. Existing literature in robotics explored many different planning algorithms for planning a single trajectory to planning a complete sequence of tasks where continuity is maintained [Garrett et al, 2021]. Many application literature focused on the TAMP for service robots, medical robots, and self-driving cars, while there are few examples for architectural applications. For digital fabrication and automated construction, the planning method has to be adapted to the needs of architectural assemblies and the scale of construction [Leung et al, 2021]. Some of the unique challenges are the highly bespoke workpiece and assembly geometry, the large workpiece (e.g., long beams), and a dense collision environment. This three-day hybrid workshop addressed the needs of the architectural robotics community to use industrial robotic arms to assemble highly bespoke objects. The objects do not have any repetitive parts or assembly targets. The workshop leaders shared their experiences using industrial robots to construct large-scale timber structures. One of the most useful techniques is the recently published “Flowchart Planning Method,” where task sequence is planned using a flowchart, and motion trajectories are planned in a second pass [Huang et al, 2021].

title	Research on Architectural Sketch to Scheme Image Based on Context Encoder
doi	https://doi.org/10.52842/conf.caadria.2023.1.069
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 69–78
summary	Architects are used to hand drawing sketches to express the architectural creation intention. To present these abstract sketches, architects and teams need to convert sketches into architectural scheme images, which requires a lot of time and labour. Deep learning may have the potential to improve the efficiency of this work. The common sketch-to-image generation is based on Generative Adversarial Network (GAN), and the research of edge-to-image has made a big progress. But these methods require strict alignment of data pairs, which is difficult to achieve. Zhu et al. proposed the loss of Cycle-Consistent, which solved the problem that pairs of data sets are difficult to collect. However, most of the image translation methods require strict alignment between image data pairs, which can be achieved only for the edge mapping extracted from the image; but the sketch is very different from the edge. Due to the abstractness and fuzziness of the sketch, any simple distortion cannot complete the task of providing pixel-level alignment between the sketch and image; And image translation is the transfer of image features such as colour and texture. The original image has a strong constraint on the generated image, which makes the original structure of the image impossible to be changed. By image inpainting, we address this topic using a joint image completion approach with Context-Encoder, where the architectural sketch provides the image context for generating the scheme images. This setting has two advantages: first, the joint images can avoid the complexity of cross modal problems and the strict alignment of the data pairs as image-to-image translation; second, because of the weak constraint, the outputs have greater freedom, which perhaps can generate more imaginative results. The Context-Encoder generates scheme images on the data sets of general architectural sketches. The results present that the applicability of the completion method is better than that of the method of image translation. And scheme images that is different from the original architectural sketch contours have been generated.

title	Research on the Exploration of Sprayed Clay Material and Modeling System
doi	https://doi.org/10.52842/conf.caadria.2023.2.231
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 231–240
summary	As a traditional building material, clay has been used by humans for a long time. From early civilisations, to the modern dependence on new technologies, the craft of clay making is commonly linked with the use of moulds, handmade creations, ceramic extruders, etc. (Schmandt and Besserat, 1977). Clay in the form of bricks is one of the oldest building materials known (Fernandes et al, 2010). This research expands the possibilities offered by standardised bricks by testing types of clay, forms, shapes, porosity, and structural methods. The traditional way of working with clay relies on human craftsmanship and is based on the use of semi-solid clay (Fernandes et al., 2010). However, there is little research on the use of clay slurry. With the rise of 3D printing systems in recent years, research and development has been emerging on using clay as a 3D printing filament (Gürsoy, 2018). Researchers have discovered that in order for 3D-printed clay slurry to solidify quickly to support the weight of the added layers during printing, curing agents such as lime, coal ash, cement, etc. have to be added to the clay slurry. After adding these substances, clay is difficult to be reused and can have a negative effect on the environment (Chen et al., 2021). In this study, a unique method for manufacturing clay elements of intricate geometries is proposed with the help of an internal skeleton that can be continuously reused. The study introduces the process of applying clay on a special structure through spraying and showcases how this method creates various opportunities for customisation of production.

title	Fabrication of Complex Clay Structures Through an Augmented Reality Assisted Platform
doi	https://doi.org/10.52842/conf.caadria.2023.1.413

summary	The relationship between clay manufacturing and architectural design has a long trajectory that has been explored since the early 2000s. From a 3D printing or assembly perspective, using clay in combination with automated processes in architecture to achieve computational design solutions is well established. (Yuan, Leach & Menges, 2018). Craft-based clay art, however, still lacks effective computational design integration. With the improvement of Augmented Reality (AR) technologies (Driscoll et al., 2017) and the appearance of digital platforms, new opportunities to integrate clay manufacturing and computational design have emerged. The concept of digitally transferring crafting skills, using holographic guidance and machine learning, could make clay crafting accessible to more workers while creating the potential to share and exchange digital designs via an open-source manufacturing platform. In this context, this research project explores the potential of integrating computational design and clay crafting using AR. Moreover, it introduces a platform that enables AR guidance and the digital transfer of fabrication skills, allowing even amateur users with no prior making experience to produce complex clay components.

title	Parametric environment for internalization and classification of models generated by the Shap-E tool
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 1689–1698
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	The material balance of the Earth is being challenged. The year 2020 was marked as the year when the total weight of human-made materials globally surpassed the weight of all life on Earth, while it is estimated that in the years to come the growth rate of mass added to the anthroposphere will increase exponentially (Elhacham et al., 2020). In this context of hypergrowth coupled with the climate emergency, the growing rate of urbanization and the increasing social and political awareness on the matters of the Anthropocene, the topics of resource depletion or insufficiency are being reframed. This keynote lecture at ACADIA 2023 highlights the importance of redefining resources and is introducing a new cultural, design and construction paradigm. Operating from an abundance mindset rather than from scarcity (Gausa et al., 2020) presents a new paradigm, particularly relevant in the design and production of the built environment. This approach expands the definition of resources, encompassing raw, non-raw, renewable, and recyclable materials. Shifting attention to the Anthroposphere as a source rather than just a destination for processed goods has the potential to disrupt linear design patterns and enhance circularity in cities and the built environment.

summary	This paper explores the potential of material, computation, and fabrication methodologies broadly engaging a critical understanding of the human epoch, also known as the anthro- pocene era, and its impact on Earth’s geology. Man-made materials have arguably become ubiquitous and a massively distributed part of the environment, while also placing an involuntary burden on local ecologies. Nature has taken its course and swallowed these synthetic materials to create new compositions of complex conglomerations, thereby blur- ring the boundaries between the agency of man, nature, and technology (Corcoran et al. 2014). The discipline of architecture, too, must reconsider its own boundaries, and evolve to design and fabricate with these techno relics, defined here as a remnant of the techno- logical impact on our planet. In order to understand how these techno relics can be used by designers, this paper pres- ents a general framework for the research, discovery, and validation of computational and fabrication processes. This is done through the examination of the background research in using aluminum waste by leveraging pre-existing digital and physical processes. Furthermore, the paper situates the background work within the broader context of how these techno relics can be mined, or collected. This is done through the examination of a case study that follows plastic waste in the Pacific Northwest through an Indigenous lens, providing possible architectural solutions that are relevant to the building typology in the remote communities most affected.

summary	Studies have indicated that built environments affect all aspects of human life such as emotion, perception, behavior, health, and well-being (Cooper et al. 2011). Built environments are formed from the combination and juxtaposition of visible and invisible environmental variables. In recent years, common techniques such as virtual reality, augmented reality, digital twins, and artificial intelligence have enabled researchers in the field of architecture and urban design to simulate environmental conditions to investigate the impacts of environmental variables on humans. However, the studies conducted in this field of human comfort are mostly focused on the impact of environmental variables such as form, temperature, humidity, and sound, and in fewer studies, up-to-date methods and technologies have been used to simulate and investigate the impact of smell on humans. Most of the studies that have investigated the effect of ambient smell on humans, carried out in the discipline of architecture and urban design, have used traditional tools and methods (questionnaire, interview, observation) rather than advanced technology and tools drawing on neuroscientific knowledge and technique to measure the effectiveness of the ambient smell on human. They have used unmasked scents or real-world environments rather than being able to simulate environmental conditions. This article highlights the significance and necessity of employing simulation methods to investigate the impact of environmental smells on humans. Additionally, it presents the methodology of an experiment for studying the effect of indoor environment smells (with a case study of an office environment in the initial phases) on human emotions, utilizing a mixed-method approach. Analysis of some parts of the data from this experiment showed that exposure to the fragrance of the jasmine flower pleasant (flower) and the odor of the rotten orange peel (unpleasant) can cause changes in the electroencephalography (EEG) power across different bands among participants.

summary	This research project, conducted at the University of Montreal School of Architecture, presents an innovative approach to the construction of reticulated structures, focusing on the development and application of a novel, ultralight aluminum node. The node, constructed from a folded, laser-cut, 1-mm aluminum sheet, is designed to accommodate wooden linear members with varied rectangular sections, making it adaptable to bespoke geometries and low valence nodes. This innovative design offers a solution to the long-standing challenge in the construction industry of balancing cost, customization, and weight for reticulated structures through novel node designs (Abdelwahab and Tsavdaridis 2019; Dyvik et al. 2023; Chilton 2007; Rochas 2014; Hassani et al. 2020).

summary	Our everyday environment plays a significant role in shaping our social and emotional interactions. It has been empirically evidenced that natural daylight mitigates depression, insomnia, and other disorders (Weber, 2022). This resonates with the fact that individuals with disrupted circadian rhythms are more susceptible to mental health perturbations (Menculini et al., 2018). The current investigation delves into the correlation between luminosity and spatial configuration within the Guillermo Grantt Benavente Psychiatry Service in Concepción, Chile. The contention is that proficient spatial connectivity and exposure to natural daylight can potentially enhance therapeutic dimensions. The overarching objective is to comprehend this nexus for formulating an architectural design methodology. Specific objectives encompass: 1. Defining the communal spaces under scrutiny; 2. Analyzing luminosity and spatial attributes. The methodological approach encompasses a hybrid framework encompassing interviews, spatial analysis, and illuminance measurements. An intricate interrelationship among preferred spaces, illuminance, and spatial characteristics is anticipated.

title	Urban Morphology and Solar Incidence in Public Spaces - an Exploratory Correlation Analysis Through a CIM System

summary	The walkability of open spaces has been highlighted in current discussions about the production of designed environments in urban contexts (Matan, 2011). To contribute to this theme, this work selects the environmental comfort of open spaces as its element of study. The production of urban space was investigated, specifically in regard to urban morphology, understanding that city design directly influences environmental comfort (Jacobs, 1996). This work addresses the geographic context of low latitudes, specifically in hot and humid climate zones of Brazil, and, in this context, according to NBR 15220 (national performance standards), shading is one of the main comfort strategies, so solar incidence was the approached environmental phenomenon. Thus, this work presents a digital system that performs exploratory analysis on the correlations between urban form indicators and environmental performance indicators, specifically solar incidence. The method consists of three steps: urban form modeling (1), indicator measurement (2) and correlation analysis (3). In the first stage, different spatial sections of a city in Brazil were represented in the digital environment (1). This work’s implementation instrument is based on a City Information Modeling framework (Beirao et al., 2012). Visual Programming Interface (VPI) and Geographic Information Systems (GIS) tools were used, in addition to a Relational Database Management System (RDBMS). Then, for each urban clipping, the values of morphological indicators and the incidence of solar radiation were measured (2). Based on the values of the indicators, an exploration of their correlation was carried out by statistical methods (3). The results of the correlation analysis and their correspondent scatter plots are presented. Finally, possible applications of the results for the creation of prescriptive urban planning systems are discussed, seeking to promote a sustainable urban environment.
