title	Surface Disclination Topology in Self-Reactive Shell Structures
doi	https://doi.org/10.52842/conf.acadia.2021.362
source	ACADIA 2021: Realignments: Toward Critical Computation [Proceedings of the 41st Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-986-08056-7]. Online and Global. 3-6 November 2021. edited by B. Bogosian, K. Dörfler, B. Farahi, J. Garcia del Castillo y López, J. Grant, V. Noel, S. Parascho, and J. Scott. 362-371.
summary	This paper discusses recent developments on the geometric construction and fabrication techniques associated with large-scale surface disclinations. The basic concept of disclinations recognizes the role of “defects” in the composition of materials, the strategic placement of which shapes the material by inducing curvature from initially planar elements. By acknowledging the relationship between geometry and topology that governs disclination based form-finding and material prototyping, this work consciously explores its potential at the architectural scale. Basic geometric figures and their topological transformations are documented in the context of digital modeling and simulation, fabrication, and a specific material palette. Specifically, this work builds on recent efforts by focusing on three particular areas of investigation; a) enhancing the stability of surface disclinations with a synthetic fibrous layer, b) aggregation via periodic tilings, and c) harnessing snap-through buckling to increase bending stiffness in thin surfaces.

title	An Autonomous Bio-Inspired Shading Façade System based on Plant Movement Principles
doi	https://doi.org/10.52842/conf.ecaade.2021.2.463

summary	Utilizing existing principles of plant movement, we can design climatic-responsive facades made of hygroscopic materials. This paper investigates the use of a double actuating system to create an architectural façade. Several adaptive façade strategies have been previously developed using wood bilayers, but there has not been significant investigation into the application of multiple actuation points in a single unit. The paper presents a façade that is responsive to the surrounding environment via the kinematic amplification of hygroscopic wood expansion. The kinematic amplification uses the biomechanical principles from both the Water Lily (Nymphaea) and the Purple Shamrock (Oxalis triangularis). Acting as an adaptive shading mechanism, the façade system - arranged using Lindenmayer system principles - can improve occupant comfort by controlling solar radiation . The developed prototypes use climate-responsive wood bilayer actuators. The aesthetic and functional features of the bio-inspired mechanism promote a visual awareness between our built environment and environmental conditions.

title	Thermal Performance of Nanomaterials of a Medium Size Office Building Envelope: With a Special Reference to Hot Arid Climatic Zone of Egypt
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 385-396
summary	Global warming is becoming a huge threat in the 21st century. The building is the main contributor to energy consumption and greenhouse gas emissions which play an important role in global warming. Using new technologies provides a step towards a better-built environment. Nanotechnology is an emerging technology that provides innovative materials that integrate with the building envelope to enhance energy efficiency and decrease energy consumption in buildings. Many Nano products are a promising candidate for building thermal insulation and increasing the building’s efficiency. This paper aims to reach minimum energy consumption by investigating Nanomaterials thermal performance on a building’s envelope in a hot arid climate. An office building in Cairo, Egypt is chosen as a case study. The paper presents an empirical/applied inquiry that is based on a computer simulation using Design Builder software. Energy consumption is calculated for different cases; the base model of the office building without using nanomaterials, and several nano models using nanomaterials. The results indicate that the use of Nanomaterials can enhance the thermal performance of the office building and save about 13.44 % of the annual energy consumption of the building.

title	Optimizing container housing units for informal settlements - A parametric simulation & visualization workflow for architectural resilience
doi	https://doi.org/10.52842/conf.caadria.2021.1.051
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. 51-60
summary	In rapidly growing cities like Dhaka, Bangladesh, sustainable housing in urban wetlands and slums present a challenge to more affordable and livable cities. The Container Housing System (CHS) is among the latest methods of affordable, modular housing quickly gaining acceptance among local stakeholders in Bangladesh. Even though container houses made of heat-conducting materials significantly impact overall energy consumption, there is little research on the overall environmental impact of CHS. Therefore, this study aims to investigate the performance of CHS in the climatic context of the Korail slum in Dhaka. The paper proposes a building envelope optimization and visualization workflow utilizing parametric cluster simulation modeling, multi-objective optimization (MOO) algorithms, and virtual reality (VR) as an immersive visualization technique. First, local housing and courtyard patterns were used to develop hypothetical housing clusters. Next, the CHS design variables were chosen to conduct the MOO analysis to measure Useful Daylight Illuminance and Energy Use Intensity. Finally, the prototype was integrated into a parametric VR environment to enable local stakeholders to walk through the clusters with the goal of generating feedback. This study shows that the proposed method can be implemented by architects and planners in the early design process to help improve the stakeholders understanding of CHS and its impact on the environment. It further elaborates on the implementation results, challenges, limitations of the parametric framework, and future work needed.

title	Material (data) Intelligence - Towards a Circular Building Environment

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	Nesting Fabrication

source	ACADIA 2021: Realignments: Toward Critical Computation [Proceedings of the 41st Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-986-08056-7].

summary	Positioned at the intersection of the computational modes of design and production, this research explains the principles and applications of a novel fabrication-informed geometric system called nesting. Applying the nesting fabrication method, the authors reimage the construction of complex forms by proposing geometric arrangements that lessen material waste and reduce production time, transportation cost, and storage space requirements. Through this method, appearance and performance characteristics are contingent on fabrication constraints and material behavior. In this study, the focus is on developing design rules for this method and investigating the main parameters involved in dividing the global geometry of a complex volume into stackable components when the first component in the stack gives shape to the second. The authors introduce three different strategies for nesting fabrication: 2D, 2.5D, and 3D nesting. Which of these strategies can be used depends on the geometrical needs of the design and available tools and materials. Next, by revisiting different fabrication approaches, the authors introduce readers to the possibility of large-scale objects with considerable overhangs without the need for nearly any temporary support structures. After establishing a workflow starting with the identification of geometric rules of nesting and ending with fabrication limits, this work showcases the proposed workflow through a series of case studies, demonstrating the feasibility of the suggested method and its capacity to integrate production constraints into the design process. Traversing from pragmatic to geometrical concerns, the approach discussed here offers an integrated approach supporting functional, structural, and environmental matters important when turning material, technical, assembly, and transportation systems into geometric parameters.

title	Cocoon: 3D Printed Clay Formwork for Concrete Casting
doi	https://doi.org/10.52842/conf.acadia.2021.400
source	ACADIA 2021: Realignments: Toward Critical Computation [Proceedings of the 41st Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-986-08056-7].

summary	Concrete, a material widely used in the construction industry today for its low cost and considerable strength as a composite building material, allows designers to work with nearly any form imaginable; if the technology to build the formwork is possible. By combining two historic and widely used materials, clay and concrete, our proposed novel process, Cocoon, integrates robotic clay three-dimensional (3D) printing as the primary formwork and incrementally casting concrete into this formwork to fabricate nonstandard concrete elements. The incremental casting and printing process anchors the concrete and clay together, creating a symbiotic and harmonious relationship. The concrete’s fluidity takes shape from the 3D printed clay formwork, allowing the clay to gain structure from the concrete as it cures. As the clay loses moisture, the formwork begins to shrink, crack, and reveal the concrete below. This self-demolding process produces easily removable formwork that can then be recycled by adding water to rehydrate the clay creating a nearly zero-waste formwork. This technique outlines multiple novel design features for complex concrete structures, including extended height limit, integrated void space design, tolerable overhang, and practical solutions for clay deformation caused by the physical stress during the casting process. The novelty of the process created by 3D printing clay formwork using an industrial robotic arm allows for rapid and scalable production of nearly zero-waste customizable formwork. More significant research implications can impact the construction industry, integrating more sustainable ways to build, enabled by digital fabrication technologies.

title	Computational screening-LCA tools for early design stages
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 1, 6–22
summary	Life Cycle Assessment (LCA) has been widely adopted to identify the Global Warming Potential (GWP) in the construction industry and determine its high environmental impact through Greenhouse Gas (GHG) emissions, energy and resource consumptions. The consideration of LCA in the early stages of design is becoming increasingly important as a means to avoid costly changes at later stages of the project. However, typical LCA-based tools demand very detailed information about structural and material systems and thus become too laborious for designers in the conceptual stages, where such specifications are still loosely defined. In response, this paper presents a workflow for LCA-based evaluation where the selection of the construction system and material is kept open to compare the impacts of alternative design variants. We achieve this through a strict division into support and infill systems and a simplified visualization of a schematic floor layout using a shoebox approach, inspired from the energy modelling domain. The shoeboxes in our case are repeatable modules within a schematic floor plan layout, whose enclosures are defined by parametric 2D surfaces representing total ratios of permanent supports versus infill components. Thus, the assembly of modular surface enclosures simplifies the LCA evaluation process by avoiding the need to accurately specify the physical properties of each building component across the floor plan. The presented workflow facilitates the selection of alternative structural systems and materials for their comparison, and outputs the Global Warming Potential (GWP) in the form of an intuitive visualization output. The workflow for simplified evaluation is illustrated through a case study that compares the GWP for selected combinations of material choice and construction systems.

title	The Use of Natural Materials in Additive Manufacturing of Buildings Components - Towards a more sustainable architecture

summary	The demand for sustainable building materials is currently a major concern of society. It is known that the traditional construction industry requires a high consumption of inorganic materials, which is associated with the excessive production of waste. Thus, this article intends to demonstrate the possibility of using the Additive Manufacturing (AM) technique Paste Extrusion Modeling (PEM) in the production of reusable, biodegradable and recyclable construction systems, using a combination of different natural materials that have created multiple pastes with different additives.Cellulose is a natural material - biodegradable, recyclable and low cost - and its implementation aims to change some aspects of the current state of the construction sector and can have a real impact on the exploration of innovative solutions and more sustainable alternative building systems. The integration of AM techniques, PEM method, supported by computational modelling tools, will allow the definition of a building system and its components. Depending on the material used - natural materials or biomaterials - the constraints and limitations of AM will be considered.

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	Gypsum is one of the most commonly used building materials today and prevalent in architectural acoustics. However, despite its ubiquitous appropriation, few domains of research or practice seek to provide opportunistic approaches for its acoustical application. This paper outlines the computational design and fabrication processes for the development of a pavilion that explores alternative acoustic applications for gypsum. It demonstrates how sound performance can drive the conceptual agenda for a project by articulating the conditions of spatial experience through the design of architectural surface.

title	An open, integrated modular format: For flexible and intelligible architecture, engineering and construction design and production
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 1, 23–36
summary	The architecture, engineering and construction sector is fragmented, and its computer-aided design systems suffer data loss and errors in workflow between design and realisation. An open source, integrated, modular format is proposed to address the technological nature of these problems. Accordingly, this research updates the notion of the modular format as a more flexible and intelligible computational design method by leveraging knowledge from the computer science and manufacturing sectors where the design and realisation process is intentional and explicit. The research design of this article comprises a theoretical approach combined with an empirical case study. Principles of modularity are extracted from the computer science and manufacturing sectors to assist with a better definition of architecture, engineering and construction computer-aided design processes that use materials and resources more efficiently and sustainably. The methodology of the modular format contributes to the emerging concept of a building lifecycle management system for the architecture, engineering and construction sector.

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	Optimal design of wooden pavilion gridshell structures in the context of architectural and structural collaboration

summary	In the article two interacting aspects of collaborative design are described: shaping of the form and the rational use of materials. Form shaping will be analyzed on the basis of pavilions. The material aspect of this paper is concerned with the use of wood in contemporary construction. The first goal is to analyze the selected technical parameters related to the use of wood in the optimal shaping of gridshell structures in architecture. The second goal is to identify new opportunities for architectural and structural engineering cooperation in the context of generative digital tools. The possibility of creating new plugins for the existing generative modeling programs to improve the quality of collaboration will also be discussed. The paper is concerned with elementary research. I was able to achieve the set goals by means of theoretical analyzes based on the known literature as well as the analysis of the created objects and the accompanying research. The background for the work is a description of the selected trends of using natural wood as load-bearing elements in contemporary architecture and case studies of the selected objects that express the idea of form and material eco-efficiency.

summary	Augmented Reality (AR) has the potential to create a paradigm shift in the production of architecture. This paper discusses the assembly and evaluation of a bamboo prototype installation aided by holographic instructions. The case study is situated within the framework of AR-driven computational design implementation methods that incorporate feedback loops between the as-built and the digital model. The prototype construction aims to contribute to the ongoing international debate on architectural applications of digital technology and computational design tools and on the impact these have on craftsmanship and architecture fabrication. The case study uses AR-aided construction techniques to augment existing bamboo craftsmanship in order to expand its practically feasible design solution space. Participating laypersons were challenged to work at the interface of technology and material culture and engage with both latest AR systems and century-old bamboo craft. This paper reflects on how AR tracking can be used to create a constant feedback loop between as-built installations and digitally designed source models and how this allows for the real-time assessment of design fidelity and deviations. The case study illustrates that this is especially advantageous when working with naturally varying materials, like bamboo, whose properties and behaviour cannot straightforwardly be accurately simulated digitally. The paper concludes by discussing how augmented feedback loops within the fabrication cycle can facilitate real-time refinement of digital simulation tools with the potential to save time, cost, and material. The augmentation of onsite available skills facilitates the democratisation of non-standard architecture design production.

summary	The project develops pre- and post-demolition digital assessment protocols in order to better inform reclaimed material implementation in new projects. The application of the protocols are demonstrated in a pavilion constructed of reused timber (Figure 1). By facilitating the data capture, analysis, identification, and characterization of available secondary raw materials, and creating database systems for pre- and post-demolition sites, it promotes gains in high quality upcycled materials for new construction projects. Modern reality capture technologies allow for collecting high density and quality Construction and Demolition Waste (CDW) data, presenting the opportunity to also increase the reliability and trust in upcycled materials by data specifically structured to relevant actors.

title	ClayKnit - A composite structure of clay and knitted meshes

summary	In this paper, we will demonstrate a new method of using knitted meshes to act as a formwork and to reinforce thin and hollow spatial clay structures. Currently, ceramic elements in the building industry are formed using extruding, pressing, or casting methods. This new approach can increase the usability of digitally fabricated lightweight elements, by spraying clay onto mass customised knitted meshes. Compared to fabrics that are used to shape concrete as a stay-in-place formwork, knitted meshes are available in various densities and changing patterns. They also offer the possibility to use a non-flexible thread as an elastic mesh. Knitted meshes are formed in a predefined shape by stretching them without the use of elaborate scaffolding. A specific liquid clay mixture is applied by spraying multiple layers onto the mesh by an industrial, six-axis robotic arm to precisely achieve variable wall thicknesses. Due to the complementary qualities of clay, which absorbs compressive forces and the threads, which absorb tensile forces, structures can be designed with a material optimisation scheme. To demonstrate the potential of such composite materials and the building process itself, a 1:1 lightweight module was constructed as an architectural prototype.

summary	The main objective of the research was to determine the possibilities and limitations of digital design and digital fabrication with 3D printing of a cell prototype. The work was structured in 3 stages: Rationale, Materials and Logistics, and Experimentation. The Rationale stage consisted of reviewing the literature on the concepts: Prototype, Bionics, Parametric Design, Digital Fabrication and 3D Printing. The Materials and Logistics stage consisted of the presentation and classification into categories of materials and the logistics that were used. The Experimentation stage consisted of 3 phases: determination of the structural characteristics of the fruit peels; determination of the shape of the cell from the structural characteristics of the fruit peels and; choice of 3D printing digital manufacturing technology. The main result of the research was that digital technologies - MEV Jeol JSM-7000F microscope, Rhinoceros 5.0 software, Grasshopper software - allow to observe and design a cell in a complex way inspired by the natural structures found in the peels of fruit species of Annona Cherimola, Mill with Annona Squamosa, L; Mauritia Flexuosa; Babassu Coconut, Soursop and Pine Cone or fruit of the Earl.

summary	This research has as main objective to determine the possibilities and limitations of digital design and digital fabrication by 3D printing of a prototype of bionic pavilion with non-Euclidean geometric shapes in reduced size inspired by fruits present in the MidWest Region of Brazil. The work was structured in 3 stages: Rationale, Materials and Logistic, and Experimentation. The Rationale consisted of a literature review on the concepts of: bionics, generative-algorithmic design, digital fabrication, 3D printing and prototyping. The Materials and Logistics stage consisted of the presentation and classification into categories of materials and the logistics that were usedTthe experiment consisted of 4 phases: Graphic code and 3D digital modeling of the bionic pavilion; operationalization of digital fabrication; selection of 3D printing digital fabrication technology and; digital fabrication by 3D printing. The main result of the research is that digital technologies - rhinoceros 5.0 software, grasshopper software - allow to design a prototype of a pavilion of complex shape or of small size inspired by natural structures.

summary	The global construction industry is the single largest consumer of materials on the planet. Of that material consumption anywhere between 10-20% will end up in landfills as waste. Currently, there are three approaches to tackle this problem - reduce, reuse, and recycle. Concentrating purely on the challenge of reducing waste this research aims to address the problem of waste in the construction industry by addressing it in the preliminary design stage. It does so by asking the research question if computational design offers opportunities towards lean construction or to achieve Zero Waste by understanding waste as a data management challenge. For our research materials are specified in databases outlining geometrical and quantitative information either in material supplier databases (homepage) or in architecture and construction databases via Revit or Grasshopper. Consequently, one can collect via web scraping, investigate via databases, inspect and compare via Grasshopper and Python these databases to understand if one can transform data into information towards material use and consequently into knowledge on waste production and reduction. This investigation, its proposed hypothesis, methodology, implications, significance, and evaluation are presented in the paper.
