title	Wedged Kerfing. Design and Fabrication Experiments in Programmed Wood Bending
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. 1283–1294
summary	Wood as a construction material gained interest in the last decade because of its low carbon footprint and the continuous research of new design possibilities opened using computational and robotic means. The shaping of timber into non-standard shapes is challenging and industrially demanding. This paper showcases a method to computationally control the formation of curved wood elements suitable for construction purposes. The aim is to achieve wood bending and twisting through a technique that combines advanced kerfing with a controlled insertion of wedges. The research has been conducted through material testing, computational developments, and robotic prototyping to evaluate design control, fabrication accuracy, and structural potential for architectural applications.

summary	This /practice-based design research/ investigates the possibility of computational design to increase agency and impact in emerging economies through real-world projects. By cultivating a new kind of relationship to issues in development and local untapped resources, they inspire for more public engagement and resource-based conversations within a spatial framework. The topics that were addressed in this research are the democratization of data and affordability of construction. These two on-going early-stage initiatives have used computational design tools at specific areas in the projects development, therefore optimizing the parts where low-tech tools werent sufficient. This demand driven design process explores ways in which different levels of technology can augment each other.

title	Assessing Santa Marta: Using Evaluation Tools to Inform Parametric Urban Design

summary	Lack of affordable housing is a worldwide problem. Rapid urbanization, rural exodus, and poor governance policies have contributed to the problem and, in response, low-income populations resort to self-construction. The result are informal settlements located predominantly in marginalized urban areas (United Nations, 2015) that develop with neither urban infrastructure nor compliance with building and planning codes (Lall et al., 2006; Patel et al., 2018; United Nations Human Settlements Programme, 2012) and, consequently, offer a poor-quality built environment. The goal of this paper is to methodologically identify physical aspects of such built environments that could be improved. We evaluate a case study, the Santa Marta favela in Brazil, using a holistic housing-quality assessment tool and local building and planning codes as reference. Our results identify the physical characteristics with lower quality standards in the case study and demonstrate the efficacy of the methodology introduced for this purpose.

title	Reusable Augmented Concrete Casting System - Accessible method for formwork manufacturing through holographic guidance

summary	Reinforced concrete has been one of the essential materials for modern architecture for the last hundred years. Its use is entirely global, having been adopted by all cultures and styles since its invention in the late 19th century. Although its value is excellent due to its low cost, durability and adaptability, its environmental impact is significant, being, in fact, one of the most polluting industries in the world (Babor et al. 2009). This experimental project will research a more sustainable use of concrete, exploring a new form of reusable concrete formwork that will ideally reduce the CO2 footprint by removing wood waste in the casting process and replacing it with adaptable metal components. The modular part-based system for the concrete casting also attempts to simplify one of the current complexities for concrete construction, the Skilled-Labour shortage. (Yusoff et al. 2021). To mitigate this problem, the project also proposes using an Augmented Assembly logic for the casting parts to guide the ensemble and dismantle the formwork through an optimised algorithmic logic. The use of Augmented Reality as a replacement for traditional paper instructions will facilitate access to more workers to this construction art and potentially improve access to optimised use of concrete in developing communities with restricted building technological resources.

title	A decision support tool for building design: An integrated generative design, optimisation and life cycle performance approach
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 3, 401–430
summary	Building performance evaluation is generally carried out through a non-automated process, where computational models are iteratively built and simulated, and their energy demand is calculated. This study presents a computational tool that automates the generation of optimal building designs in respect of their Life Cycle Carbon Footprint (LCCF) and Life Cycle Costs (LCC). This is achieved by an integration of three computational concepts: (a) A designated space-allocation generative-design application, (b) Using building geometry as a parameter in NSGA-II optimization and (c) Life Cycle performance (embodied carbon and operational carbon, through the use of thermal simulations for LCCF and LCC calculation). Examining the generation of a two-storey terrace house building, located in London, UK, the study shows that a set of building parameters combinations that resulted with a pareto front of near-optimal buildings, in terms of LCCF and LCC, could be identified by using the tool. The study shows that 80% of the optimal building’s LCCF are related to the building operational stage (o= 2), while 77% of the building’s LCC is related to the initial capital investment (o= 2). Analysis further suggests that space heating is the largest contributor to the building’s emissions, while it has a relatively low impact on costs. Examining the optimal building in terms compliance requirements (the building with the best operational performance), the study demonstrated how this building performs poorly in terms of Life Cycle performance. The paper further presents an analysis of various life-cycle aspects, for example, a year-by-year performance breakdown, and an investigation into operational and embodied carbon emissions.

title	Expanding Bending-Active Bamboo Gridshell Structures' Design Solution Space Through Hybrid Assembly Systems
doi	https://doi.org/10.52842/conf.caadria.2021.1.331
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. 331-340
summary	This paper discusses the development and testing of a novel design method for the low-tech construction of bending-active bamboo gridshell structures. It expands this typologys current design solution space by combining and building up on two common production methods for light-weight shell structures: 1) the lay-up method, typically used in bamboo architecture in which members are added one at a time, and 2) the flatbed method, in which a prefabricated equidistant flat grid without shear rigidity is propped up and deformed into its final doubly curved shape. The novel methodology expands the systems design solution space by incorporating singularities within the grid topology and by layering multiple separate grids. This allows for spatially radically different building geometries without loss of implementation workflow efficiency. A demonstrator design project, tested through a large-scale prototype model, is described to illustrate the possible spatially engaging architectural design opportunities presented by the novel approach.

title	Co-Designing Material-Robot Construction Behaviors
doi	https://doi.org/10.52842/conf.acadia.2021.470
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. 470-479.
summary	This paper presents research on designing distributed, robotic construction systems in which robots are taught construction behaviors relative to the elastic bending of natural building materials. Using this behavioral relationship as a driver, the robotic system is developed to deal with the unpredictability of natural materials in construction and further to engage their dynamic characteristics as methods of locomotion and manipulation during the assembly of actively bent structures. Such an approach has the potential to unlock robotic building practice with rapid-renewable materials, whose short crop cycles and small carbon footprints make them particularly important inroads to sustainable construction. The research is conducted through an initial case study in which a mobile robot learns a control policy for elastically bending bamboo bundles into designed configurations using deep reinforcement learning algorithms. This policy is utilized in the process of designing relevant structures, and for the in-situ assembly of these designs. These concepts are further investigated through the co-design and physical prototyping of a mobile robot and the construction of bundled bamboo structures. This research demonstrates a shift from an approach of absolute control and predictability to behavior-based methods of assembly. With this, materials and processes that are often considered too labor-intensive or unpredictable can be reintroduced. This reintroduction leads to new insights in architectural design and construction, where design outcome is uniquely tied to the building material and its assembly logic. This highly material-driven approach sets the stage for developing an effective, sustainable, light-touch method of building using natural materials.

summary	Geometrically complex building components‚ reliance on high-touch implementation often results in tedious information reprocessing. Recent use of Mixed Reality (MR) in architectural practices, however, can reduce data translation and potentially increase design-to-build efficiency. This paper uses Aurora, a single-story residential building for 2021 China‚s Solar Decathlon Competition, as a demonstrator to evaluate the performance of on-site holographic building construction. This paper firstly reviews recent studies of MR in architectural design and practice. It then describes an MR-aided construction process of Aurora's non-standard building envelope and rooftop mounting structure, where in-situ holographic registration, human-machine cooperation, and as-built analysis are discussed. This paper concludes by stating that MR technologies provide unskilled implementers with a handy approach to materialise complex designs. The research was guided by the UN Sustainable Development Goals, especially aligning with the GOAL 9 which seeks innovations in industry and infrastructure.

summary	This paper examines the suitability of existing robotic technologies and large-scale 3D printing techniques for the fabrication of three-dimensional printed building components to be applied in the Saudi housing construction industry. The paper assesses a series of cases based on the applications for 3D-printing cement-based materials in construction. In particular, we investigate five different additive manufacturing techniques and evaluate their performance in terms of their flexibility/mechanism, control/navigation, calibration/operation system, fabrication suitability (in-situ or off-site), size of printed components, printing speed. The findings include in a matrix chart, where the advantages and disadvantages of each technique become evident. The paper further evaluates the suitability of each technique in relation to the particular climatical and socio-political context of Saudi Arabia, applicable to other construction industries with similar conditions.

summary	This paper is examining the development of a design and fabrication framework aiming to increase the efficiency of the construction of concrete building components by introducing 3D concrete printing in the context of Saudi Arabia. In particular, we will present an algorithmic process focusing on the design and fabrication of a typical, mass customised, single-family house, which incorporates parametric modelling, topology optimisation, finite element (FE) analysis and robotic 3D printing techniques. We will test and verify our framework by designing and fabricating a loadbearing concrete column with structural and material properties defined by the Saudi Building Code of Construction. Our findings are highlighting the advantages and challenges of the proposed file-to-factory framework in comparison to the conventional construction methods currently applied in Saudi Arabia, or other similar sociopolitical contexts. By comparing the material usage in both conventional and optimised columns, the results have shown that material consumption has been reduced by 25%, the required labour in the construction site has been mitigated by 28 and the duration time has been reduced by 80% without the need for formwork.

title	Consistency Checker - An automatic constraint-based evaluator for housing spatial configurations
doi	https://doi.org/10.52842/conf.ecaade.2021.2.351
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. 351-358
summary	The gradual rise of artificial intelligence (AI) and its increasing visibility among many research disciplines affected Computer-Aided Architectural Design (CAAD). Architectural deep learning (DL) approaches are being developed and published on a regular basis, such as retrieval (Sharma et al. 2017) or design style manipulation (Newton 2019; Silvestre et al. 2016). However, there seems to be no method to evaluate highly constrained spatial configurations for specific architectural domains (such as housing or office buildings) based on basic architectural principles and everyday practices. This paper introduces an automatic constraint-based consistency checker to evaluate the coherency of semantic spatial configurations of housing construction using a small set of design principles to evaluate our DL approaches. The consistency checker informs about the overall performance of a spatial configuration followed by whether it is open/closed and the constraints it didn't satisfy. This paper deals with the relation of spaces processed as mathematically formalized graphs contrary to existing model checking software like Solibri.

summary	This paper proposes the development of a methodology for the digital generation of valid 3D-printed houses designs and fabrication programming, in the search for an emerging architectural language of this technology. The aim is to develop a transparent, generic and variable modeling and management process, based on some parametric patterns for 3D printing, architectural and construction design knowledge. That serves as an outline or insight of what can be designing architectural 3d-printed forms in the Construction 4.0 era. Preliminary results, discussion and further work are presented.

summary	This paper presents a study developed in the scope of an ongoing research about the creation of an architectural design system of low-cost housing in Portugal's context. Its goal is to present the survey, analysis and digitization work of a research carried out in the 1960s by Portuguese architect Nuno Portas, with the help of architect Alexandre Alves Costa. The method was to convert mathematical information contained in Portas' and Alves Costa's report from Lisbon's National Laboratory of Civil Engineering (LNEC) into an algorithmic model with Rhinoceros® and Grasshopper® software. Besides revealing for the first time a comprehensive study of this pioneering work, this paper will set the foundations to propose the adaptation of its process into low-cost housing design. The result presented here is an algorithm for selecting the best architectural type from a database of housing floor plans, analyzed by a questionnaire regarding the inhabitants' needs and satisfactions.

summary	There has been a recent increase in the exploration of mereological systems, speculating on how digital design, assembly and reconfiguration of digital materials (Gershenfeld, 2015) enables digitally informed physical worlds that change over time. Besides opportunities for construction and design automation, there is a potential to reimagine how multiple stakeholders can participate in the computational decision-making process, using the benefits of the mass customization of logistics (Retsin, 2019). This paper presents a research-by-design project that applies a digital and discrete material system to high-rise housing in Hong Kong. The project has developed an integrated approach to design, construction, and inhabitation, using a system of discrete parts which can be assembled in various apartment configurations, to incorporate varying occupants requirements and facilitate negotiations and changes over time.

title	Prefabrication 4.0: BIM-aided design of sustainable DIY-oriented houses
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 2, 142–156
summary	In the context of continuous housing shortage, increasing construction standards and rising labour costs, one of the possibilities to address this array of problems is prefabrication directed towards do-it-yourself (DIY) construction methods. This paper presents a prototype tool for aiding the design of DIY-oriented single-family houses with the use of small-element timber prefabrication. The introduced solution uses the potential of BIM technology for adapting a traditionally designed house to the prefabrication requirements and reduction of waste generated in the assembly process. The experimental tool was developed in the Autodesk Revit software. It incorporates custom Dynamo-for-Revit scripts. The experimental tool implemented the user- and technology-specified boundary conditions and converted an input BIM model into a prefabricated alternative. The tool was tested on the design of a two-story single-family house. The results compare the automated optimized panelization with manual approach. The simulation revealed the possibility of the construction waste reduction by at least 50% when comparing to the non-optimized panelization.

summary	Assisted self-construction has been proclaimed by the UN Habitat as one of the most affordable methods of providing sustainable housing. Self-construction in informal settlements is analogous with incremental development, where design and construction occur in simultaneous waves. However, unassisted self-construction often produces housing of substandard quality owing to a lack of knowledge and resources. This paper hypothesizes that the core factor leading to substandard housing in informal self-construction is an information and communication gap in the existing process. In order to identify the gap, a mapping and analysis exercise is carried out that identifies the focal points where the informal system deviates from the formal, the decisions that influence these deviations, and the impact of these deviations on the overall output. The paper develops the framework for a smartphone-based, digital technical aid system, that fills this information and communication gap and provides construction guidance to owner-builders without compromising the nonlinear nature of incremental development.

title	Towards a Digital Workflow for Designing Bistable Kinetic Façades

summary	New engineered materials present an excellent opportunity for architects and researchers to reimagine traditionally static building components as dynamic and shape-changing. Bistable materials show two zero energy states and can transition between them with the input of a small force. These engineered materials have yet to be explored for large-scale architectural applications. This study presents a digital workflow for designing a kinetic shading system for facades with bistable laminates. The workflow includes an FEA model that predicts the curved shape of bistable laminates and a digital simulation model that predicts the natural light performance of the resulting kinetic screens. We describe the workflow and demonstrate its use with a case study of a manually operated bistable facade. The study forms part of a larger research agenda to develop kinetic architectural systems using bistable and smart materials.

summary	Architecture has a substantial influence worldwide as it shapes our cities, and it is made to last. Urban areas are also responsible for 70% of the world’s carbon emissions. Consequently, architects are responsible for minimising the destructive effects of construction on the environment. How can biological intelligence be inserted in architecture as a possibility to increase environmental performance? Bio-design goes further than biology-inspired approaches. Biodesign refers to incorporating living organisms as an essential component of a system, changing the natural and built environment boundaries. It contains living and machine intelligence, whether embedded in the design process or in the building itself. This paper seeks to give an overview of bio-design and how it can be seen as a strategy of thinking of new research pathways.

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.
