summary	This study examines composite compositions based on fiber-based materials. It focuses on organic textiles of Jute, Hemp, Wool, Flax, and Glass fiber as a synthetic textile, combined with the lightweight wood species Paulownia. By creating novel composites, the study aims to investigate methods and generate design knowledge for material strategies to improve and reduce material waste in the built environment, further enabled by the use of small elements that can be sourced from waste wood and reclaimed wood. Research is conducted as a hybrid material-computational methodology, developing and testing probes, prototypes and a full-scale demonstrator assembly in the form of a wall seating composition. The results find that the proposed method and resulting composites have significant potentials for both expressive and functional characteristics, allowing tectonic articulation to be made, while creating minimum material structures based on assembly of small elements to larger complex curvature building parts.

title	Optimising Harbour Typology in the Form Finding Process using Computational Design: A case study of a Greenfield port facility
doi	https://doi.org/10.52842/conf.caadria.2021.2.619

summary	The bulk of computational design strategies and research have been focused on issues related to architectural form and building systems. This is done by employing computational tools to optimise architectural forms, building performance and generally, improve quality of living. Many of these methodologies are based on the concept of form finding - varying geometric elements to generate and evaluate options to derive optimised solutions. However, beyond building designs, the concept of form finding can find its relevance in other design applications too such as engineering, landscape, and in our case, the design of ports, or more specifically harbour typology. In most building scenarios, the plot of land earmarked for development is typically selected beforehand, hence little exploration have been done to optimise land topology, when in fact the profile of land is the governing feature in most designs. For performance driven facilities like ports with high economic and political impact, there is value in optimizing topology to maximise throughput. Through the multi-disciplinary and collaborative effort of stakeholders and specialists, our project explored optimizing harbour topology via performance-based approach using computational design. The phenomenon, including impact and effects of trade-offs, are discussed and presented in this paper through a case study of a Greenfield port facility.

title	Daylighting and the Elderly: A Study of Daylight Accessibility and Envelope Retrofit in Southern Chile's Senior Home
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. 1333–1344
summary	In the next 25 years, the elderly population will increase on average to 65 thousand people annually in Chile (INE, 2018). Their independent living is jeopardized partially for diminished visual capacity that difficult spatial perception. Although light does not correct vision impairment, adequate light levels can respond to the needs of older people as preventing visual errors. This study evaluates daylighting availability in an assisting living residence in a southern city in Chile. A quantitative approach resulted in the identification of envelope-retrofit strategies that allow achieving recommended levels of natural lighting, particularly in shared spaces where residents spend most of the day. The results show that it would be possible to achieve better light availability, as it also allows for a better understanding of the contributions of the building envelope. Finally, the study outlines recommendations for future retrofits that meet requirements for visual comfort for a growing senior population.

summary	The integration of repurposed material in new construction products generates resiliency strategies that diminish the dependency on raw resources and reduce the CO2 emissions produced by their extraction, transportation, and manufacturing. This research emphasizes the need to expand preliminary data collation from pre-demolition sites to inform early design decisions. Material (data) Intelligence investigates how the merging of artificial intelligence and data analysis could have a crucial impact on achieving widespread material reuse. The first step consists of automating the process of detecting materials and construction elements from pre-demolition sites through drone photography and computer vision. The second part of the research links the resulting database with a computational design tool that can be integrated into construction software. This paper strengthens the potential of circular material flows in a digital paradigm and exposes the capability for constructing big data sets of reusable materials, digitally available, for sharing and organizing material harvesting.

title	Material-informed Formwork Geometry - The effects of cross-sectional variation and patterns on the strength of 3D printed eggshell formworks
doi	https://doi.org/10.52842/conf.ecaade.2021.2.199
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. 199-208
summary	Fused deposition modelling (FDM) 3D printing of formworks for concrete has the potential to increase geometric freedom in concrete construction. However, one major limitation of FDM printed formworks is that they are fragile and often cannot support the hydrostatic pressure exerted by the concrete. The research project 'Eggshell' combines robotic 3D printing of formwork with the casting of a fast-hardening concrete to reduce hydrostatic pressure to a minimum. Eggshell can be used to fabricate architectural-scale building components; however, knowledge of the influence formwork geometry has on the hydrostatic pressure resistance is still sparse, resulting in unexpected breakages of the formwork. This paper presents an empirical study into the breakage behaviour of FDM printed formworks when subjected to hydrostatic pressure. Firstly, the study aims to give a first insight into the breakage behaviour of formworks with a constant cross-section by casting a self-compacting concrete into the formwork until breakage. Then, we investigate if three-dimensional patterning of the formwork can have a beneficial effect on the breakage behaviour. Finally, the preliminary results are validated through the fabrication of two full-scale columns. The empirical results point towards the fact that sharp corners in formworks are weaker compared to rounded corners. Although the presented results are still preliminary, they mark an important step in the development of reliable design and fabrication strategies using 3D printed formworks.

summary	This pavilion project was built as an outcome of an undergraduate design studio and design practicum at the American University of Sharjah in the UAE. The research methodology for the studio included case studies of various traditional building types to understand how traditional architecture in the MENA (Middle East and North Africa) region has been intelligently shaped by desert climate and Islamic culture over hundreds of years. Understanding and analysis of the precedent projects helped students to formulate climatic, structural, and material strategies for their design endeavors. Of the thirteen conceptual building envelopes developed by thirteen students in the design studio, the Al Janah scheme was chosen for development and construction.

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.

title	The influence of spatial geometric parameters of Glazed-atrium on office building energy consumption in the hot summer-warm winter region of China
doi	https://doi.org/10.52842/conf.caadria.2021.1.391
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 1, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 391-400
summary	To investigate the influence of the spatial geometric parameters of glazed-atrium on building energy consumption, this study established a prototypical office building model in the hot summer-warm winter region in China, and simulated the effect of energy consumption of six selected factors based on orthogonal experimental design (OED). Through the statistical analysis, the results showed that the floor height and the skylight-roof ratio were the most important parameters affecting the total energy consumption, with the contribution rates of 55.5% and 18.2%, followed by the section shape parameter and the plane orientation. In addition, the floor height and the section shape parameter were closely related to the cooling load and the lighting load, respectively, and both energy consumption could be reduced to a lower degree when the atrium inner interface window-wall ratio was 60%. Finally, the optimized parameter combination and energy-saving design strategies were proposed. This study provides architects with a simplified energy evaluation of atrium spatial geometric parameters in the early design stage, and it has an important guiding significance for the sustainable development of office buildings in the future.

title	Constrained Multi-Criteria Optimization for Integrated Design in Professional Practice
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. 29–40
summary	To design sustainable architecture, theory encourages architects to rely on automated exploration processes. In practice, the problems encountered are often multicriteria and under constraint. This paper compares different constraint handling strategies, approachable to designer, for processes involving evolutionary algorithms. Four methods are tested on a case study from professional practice. Two methods rely on parametric models: the penalty function method and the use of hyperparameters. The others involve the use of generative techniques: a rule-based method and a repair algorithm that takes the form of an agent-based model. This study highlights the significant impact of the choice of the constraint management method on exploration performance. Among other results, it appears that models involving the use of generative techniques are more efficient than those using parametric models. This calls for the development of dedicated tools.

title	Digital Fabrication of Growth - Combining digital manufacturing of clay with natural growth of mycelium
doi	https://doi.org/10.52842/conf.caadria.2021.1.753

summary	In this paper we will demonstrate that a digital workflow and a living material such as mycelium, make the creation of smart structural designs possible. Ceramics industries are not as technically advanced in terms of digital fabrication, as the concrete or steel industries are. At the same time, bio-based materials that use growth as a manufacturing method, are often lacking in basic research. Our interdisciplinary research combines digital manufacturing - allowing a controlled material distribution, with the use of mycelial growth - enabling fibre connections on a microscopic scale. We developed a structure that uses material informed toolpaths for paste-based extrusion, which are built on the foundation of experiments that compare material properties and observations of growth. In this manner the tensile strength of 3D printed unfired clay elements was increased by using mycelium as an intelligently oriented fibre reinforcement. Assembling clay-mycelium composites in a living state allows force-transmitting connections within the structure. The composite named 'MyCera' has exhibited structural properties that open up the possibility of its implementation in the building industry. In this context it allows the design and efficient manufacturing of lightweight ceramic constructions customized to this composite, which would not have been possible using conventional ceramics fabrication methods.

summary	The dynamics of COVID-19 spread have been studied from an epidemiological perspective, at city, country, and global scales (Rabajante, 2020, Ma, 2020, and Giuliani et al., 2020), although after two years of the pandemic we know that viruses spread mostly through built environments. This study is part of the Spatiotemporal Modeling of COVID-19 spread in buildings research (Gomez, Hadi, and Kemenova et al., 2020 and 2021), which proposes a multidimensional model that integrates spatial configurations, temporal use of spaces, and virus characteristics into one multidimensional model. This paper presents a specific branch of this model that analyzes the behavioral parameters, such as vaccination, masking, and mRNA booster rates, and compares them to reducing room occupancy. We focused on human behavior, specifically human interactions within six feet. We utilized the multipurpose simulation software, AnyLogic, to quantify individual exposure to the virus, in the high school building by Perkins and Will. The results show how the most effective solution, reducing the occupancy rates or redesigning layouts, being the most impractical one, is as effective as 80% of the population getting a third boost.

title	Augmented Accuracy - A human-machine integrated adaptive fabrication workflow for bamboo construction utilizing computer vision
doi	https://doi.org/10.52842/conf.ecaade.2021.1.345
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 345-354
summary	Despite being sustainable, strong and lightweight, naturally grown bamboo poles are currently used in restricted building typologies. This is due to the large tolerances in the built structures, which is caused by the variations in the dimensions and geometry of natural material as well as the manual, uninformed and imprecise assembly methods. In previous work, we introduced an adaptive fabrication method for bamboo structures that can monitor the fabrication process and compensate for deviations between built and designed form. As a proof of concept, the method is suitable for small scale bamboo structures in 2D- or simple 3D configuration. This paper extends the previous method by integrating the adaptation strategies into a cohesive fabrication and assembly workflow for large scale complex bamboo structures. To enable that, a more effective sensor localization method, adaptation algorithm, connection and assembly system, as well as web-based user interface are developed. The effectiveness of the proposed methods is demonstrated through the fabrication of a pavilion scale branching bamboo structure that complies with intended geometric boundary conditions. Even though the material has substantial geometrical variations, the final structure shows small geometric deviations and a successful interface with the prefabricated roof elements. Our work shows how vernacular materials and processes can be digitally augmented in order to reliably produce building structures, hence enabling their usage in modern applications to a larger extent.

title	Beyond Embodiment - An Existential Project of Digital Tectonics in the Posthumanist Discourses

summary	The paper is a theoretical review on the nature of tectonic expressions in the context of digital design and construction. By investigating the origin of digital tectonics as a methodological exploration to dissolve the oppositional relationship between the digital and the tectonic, the paper identifies the lack of focus on the essential task of tectonic expression-constructing embodied experience on the building form. Therefore, the paper firstly reviews how tectonic expression is understood in its traditional sense, particularly within its indispensable relationship to human body in order to construct the empathic perception of structural dynamics. Then, the paper reveals the disassociation between human body and tectonic form in the posthumanist mode of design-to-construction of the digital age. Further, by articulating the dynamic nature of embodiment in the posthumanist scenario where the body is constantly reconstructed by the technocultural conext of the living environment, the paper proposes a theoretical model arguing for a reinterpretation of both the nature and the task of digital tectonics in order to reclaim the embodied experience in the digital age. Digital tectonics becomes an existential project that must be designed within its mutual determining relationship with the historical-cultural construction of the body-self.

summary	In this study, we introduce a newly developed method called Deep-Performance, to enable automatic environmental performance simulation prediction without the need to perform simulations, by integrating deep learning strategies. The aim is to train neural networks on datasets with thousands of building design samples and their corresponding performance simulation. The trained model would offer performance prediction for design options emerging in generative protocols. The research is a work-in-progress within a broader project aimed at automating buildings environmental performance evaluations of daylight analysis and energy simulation, using deep learning (DL) models. This paper focuses on the implementation of a supervised DL method for automating the retrieval of daylight analysis metrics, targeting successful daylight design and higher building enclosure efficiency. We have further improved a Pix2Pix model trained on 5 different datasets, each containing 6000 paired images of architectural floor plans and their daylight simulation metrics. In the inference phase, the model was able to accurately predict the daylight simulation for unseen sets of floor plans. For validation, two quantitative assessment metrics were followed to assess the predicted daylight performance against the daylight performance simulation. Both assessment metrics showed high accuracy levels.

title	PolyTile 2.0: Programmable microtextured ceramic architectural tiles embedded with environmentally responsive biofunctionality
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 1, 65–85
summary	PolyTile 2.0 interrogates the potential of programmable biofunctionalities in our constructed architectural environmentsthrough the development of advanced ceramic bio-tiles. These tiles utilize novel patterning techniques and hydrogelbiomaterials to tune surface conditions at the micro- and macroscale. This trans-disciplinary work builds upon recentadvancements in the fields of three-dimensional printing, digital ceramics, materials science, bioengineering, chemicalbiology, and architecture. PolyTile 2.0 enables designers and architects to implement biofunctionality and microscalepatterning fittingly and with the ability to continuously adjust design iterations across scales. The refinement utilizesglazing strategies as a directable fluidic device and biocompatible hydrogels as a sensing platform to further developmentsin responsive built environments. This article outlines methods for the production of bulk-scale hydrogel materials,stereolithography-based three-dimensional printed ceramic tiles, and scalable glazing techniques, which bring building-scale application of this technology to the foreground.

summary	The paper based on microclimate environment of the site takes the optimized design of rural building form to help the rural revitalization and sustainable development. The reconstructedÂ house project inÂ Baihua Village of Tangchi Town in Anhui Province is taken as the research case to discuss the form optimization strategies. Based on the principle of passive priority and active optimization, the building in Baihua Village is analyzed byÂ field investigation and numerical simulation. First, the outdoor environment is interpreted by using Weather Tool software to offer a building form proposal. Then, with the drawing software CAD, ecological building simulation software Ecotect, and green building analysis software PKPM, the optimization strategy analysis of healthy building form was carried out to verify the optimal solution of building form based on Chinas national standards. Finally, this paper summarized and improved the rural building optimization design system for a healthy microclimate environment. The results of this paper are hoped to use for the contemporary rural architectural form design.

summary	Today, the living environment is much more complex due to rapid urbanization and cities hardly can bear increasing crowds. This evolving environment together with the change in living habits, put a strain on the shoulders of architects and engineers to find faster and more effective solutions towards flexible and responsive design in future city scenarios. Modular design is one of the most suitable solutions since it is based on interchangeable components that facilitate different combinations and activities responding to emerging needs and demands without demolishing a whole edifice. There are many available algorithms defining rules for the automated generation of modular building units but mainly designed for top-down solutions. This paper proposes an evolutionary approach aiming to find topological relations among the units based on a specific architectural program concerning environmental performance. Environmental conditions define the rules for the growth of units on site. The algorithm produces an automatic layout through a set of positioning rules for units organized around a core depending on a branching system. In this sense, this paper contributes to showing how rule-based modular growth on-site is shaped with environmental and architectural concerns for future city scenarios.

summary	Designing with living materials require designers to look for new methods of fabrication since living cells exhibit their own agency, and are able to sense and respond to environmental stimuli. Therefore, there is an urgent demand to design a framework for fabricating living materials. This paper investigates the digital-fabrication of fungi as a new way of designing and crafting living materials without genetic manipulation. In this research, fungi act as a bio-material probe to generate and test new design strategies that enable a dialogue between digital and biological systems. Conceptual experiments, that use fungi to investigate the proposed bio-digital-fabrication scenarios, are central in this study. The research attempts to generate new information for the design process of an organism in the field of architecture. The project will expand on the latest thinking on the bio-material fabrication by allowing the living material to be engaged in the fabrication process.
