title	Material computation—4D timber construction: Towards building-scale hygroscopic actuated, self-constructing timber surfaces
source	International Journal of Architectural Computing vol. 14 - no. 1, 49-62
summary	The implementation of active and responsive materials in architecture and construction allows for the replacement of digitally controlled mechanisms with material-based systems that can be designed and programmed with the capacity to compute and execute a behavioral response. The programming of such systems with increasingly specific response requires a material-driven computational design and fabrication strategy. This research presents techniques and technologies for significantly upscaling hygroscopically actuated timber-based systems for use as self-constructing building surfaces. The timber’s integrated hygroscopic characteristics combined with computational design techniques and existing digital fabrication methods allow for a designed processing and reassembly of discrete wood elements into large-scale multi element bilayer surfaces. This material assembly methodology enables the design and control of the encoded direction and magnitude of humidity-actuated responsive curvature at an expanded scale. Design, simulation, and material assembly tests are presented together with formal and functional configurations that incorporate self-constructing and self-rigidizing surface strategies. The presented research and prototypes initiate a shift toward a large-scale, self-construction methodology.

summary	At present the kinetics is basic, but there is no doubt that research into the field of responsive building facades will continue, to find more sophisticated design and technical solutions. This research explores the possibilities of kinetic composition afforded by Origami different techniques using squared module. Origami and paper pleating techniques are one of the conceptual design approaches from which Kinetics can be developed. The paper examines the possibilities of different arrangements of folded modules to create environmental efficient kinetic morphed skins. The paper aims to achieve different Kinetic origami-based shading screens categorized by series of parameters to provide appropriate daylighting. The main tested parameters are the form of Origami folds, the module size and motion scenarios. Ten origami cases where explored first using conceptual folded paper maquette modules, then parametrically modelled and simulated at four times of the year, 21st of March, June, September and December, taken every hour of the working day.

summary	This paper illustrates a fabrication methodology through which the inherent form of large non-linear timber components was exploited in the Wood Chip Barn project by the students of Design + Make at the Architectural Association’s Hooke Park campus. Twenty distinct Y-shaped forks are employed with minimal machining in the construction of a structural truss for the building. Through this workflow, low-value branched sections of trees are transformed into complex and valuable building components using non-standard technologies. Computational techniques, including parametric algorithms and robotic fabrication methods, were used for execution of the project. The paper addresses the various challenges encountered while processing irregular material, as well as limitations of the robotic tools. Custom algorithms, codes, and post-processors were developed and integrated with existing software packages to compensate for drawbacks of industrial and parametric platforms. The project demonstrates and proves a new methodology for working with complex, large geometries which still results in a low cost, time- and quality-efficient process.

summary	Due to climate change and the problematic amount of waste and CO2 emissions in the construction industry, non-human organisms and sustainable solutions are key motivators of the study. This paper focuses on developing a bioreceptive (Guillitte, 1995) composite suitable for additive manufacturing, composed to support growth of various organisms. It investigates key properties which have shown to be beneficial for promoting biological growth, such as water absorption, water permeability, humidity, and surface texture. The study evaluates the effect of two groups of clay-based waste additives, wooden sawdust (Arslan, et al., 2021) and sediment material sourced from local tunnel excavation in Prague. Simultaneously the need for intelligent reintegration and waste use is prevalent. Additive fabrication offers the ability to test a variety of composites and (re-)integrate them into the manufacturing processes. Current approach explores how to design artificial environments/skins for greenery and small life with the potential to improve both diversity and survivability while maintaining a better climate in its immediate surroundings. Bioreceptive design has the potential to improve the quality of the urban environment and bring new aesthetic influences into it (Cruz and Beckett 2016, p. 51-64).

title	Composite Systems for Lightweight Architectures: Case studies in large-scale CFRP winding
doi	https://doi.org/10.52842/conf.acadia.2016.326
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 326-331
summary	The introduction of lightweight Carbon Fiber Reinforced Polymer (CFRP) based systems into the discipline of architecture and design has created new opportunities for form, fabrication methodologies and material efficiencies that were previously difficult if not impossible to achieve through the utilization of traditional standardized building materials. No longer constrained by predefined material shapes, nominal dimensions, and conventional construction techniques, individual building components or entire structures can now be fabricated from a single continuous material through a means that best accomplishes the desired formal and structural objectives while creating minimal amounts of construction waste and disposable formwork. This paper investigates the design, fabrication and structural potentials of wound, pre-impregnated CFRP composites in architectural-scale applications through the lens of numeric and craft based composite winding implemented in two unique research projects (rolyPOLY + Cloud Magnet). Fitting into the larger research agenda for the CFRP-based robotic housing prototype currently underway in the “One Day House” initiative, these two projects also function as a proof of concept for CFRP monocoque and gridshell based structural systems. Through a rigorous investigation of these case studies, this paper strives to answer several questions about the integration of pre-impregnated CFRP in future full-scale interventions: What form-finding methodologies lend themselves to working with CFRP? What are the advantages and disadvantages of working with pre-impregnated CFRP tow in large-scale applications? What are efficient methods for the placement of CFRP fiber on-site? As well as how scalable is CFRP?

title	Painterface: An integrated responsive architectural interface
doi	https://doi.org/10.52842/conf.caadria.2016.271
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 271-280
summary	Interface design is one of the main research areas in human- computer interaction (HCI). In computer science, many HCI research- ers and designers explore novel interface designs with cutting-edge technology, but few investigate alternative interfaces for existing built environments, especially in the area of architecture. In this paper, we investigate alternative interface designs for existing architectural ele- ments—such as walls, floors, and ceilings—that can be created with off-the-shelf materials. Instead of merely serving as discrete sensing and display devices integrated to an existing building’s surface, these liquid and thin materials act as interventions that can be ‘painted’ on a surface, transforming it into an architectural interface. This interface, Painterface, is a responsive material intervention that serves as an an- alogue, wall-type media interface that senses and responds to people’s actions. Painterface is equipped with three sensing and responsive ca- pacities: touch, sound, and light. While the interface’s touch capacity performs tactile sensing, its sound-production and illumination capaci- ties emit notes and light respectively. The outcomes of this research suggest the possibility of a simple, inexpensive, replaceable, and even disposable interface that could serve as an architectural intervention applicable to existing building surfaces.

title	Bacterial Hygromorphs: Experiments into the Integration of Soft Technologies into Building Skins
doi	https://doi.org/10.52842/conf.acadia.2016.244
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 244-253
summary	The last few years have seen an increase in the interest to bring living systems into the process of design. Work with living systems, nonetheless, presents several challenges. Aspects such as access to specialists’ labs, samples of living systems, and knowledge to conduct experiments in controlled settings become barriers which prevent designers from developing a direct, material engagement with the material. In this paper, we propose a design methodology which combines development of experiments in laboratory settings with the use of what we call material proxies, which refer to materials that operate in analogue to some of the behaviors observed in the target organism. We will propose that combining material proxies with basic scientific experimentation constitutes a form of direct material engagement, which encourages richer exploration of the design domain. We will develop this argument by reporting on our experience in designing and delivering the primer component of a themed design studio, structured around bacterial spores as hygroscopic components of building facades. The six-week design project asked students to consider the behavior of bacterial spores, and to imagine a number of systems in which they could be employed as actuators of a membrane system that responded to fluctuations in humidity. The module is interesting in that it negotiates some of the challenges often faced by designers who want to develop a material engagement with living systems, and to produce informed speculations about their potential in architectural design.

title	Machine Learning Integration for Adaptive Building Envelopes: An Experimental Framework for Intelligent Adaptive Control
doi	https://doi.org/10.52842/conf.acadia.2016.098
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 98-105
summary	This paper describes the development of an Intelligent Adaptive Control (IAC) framework that uses machine learning to integrate responsive passive conditioning at the envelope into a building’s comprehensive conventional environmental control system. Initial results show that by leveraging adaptive computational control to orchestrate the building’s mechanical and passive systems together, there exists a demonstrably greater potential to maximize energy efficiency than can be gained by focusing on either system individually, while the addition of more passive conditioning strategies significantly increase human comfort, health and wellness building-wide. Implicitly, this project suggests that, given the development and ever increasing adoption of building automation systems, a significant new site for computational design in architecture is expanding within the post-occupancy operation of a building, in contrast to architects’ traditional focus on the building’s initial design. Through the development of an experimental framework that includes physical material testing linked to computational simulation, this project begins to describe a set of tools and procedures by which architects might better conceptualize, visualize, and experiment with the design of adaptive building envelopes. This process allows designers to ultimately engage in the opportunities presented by active systems that govern the daily interactions between a building, its inhabitants, and their environment long after construction is completed. Adaptive material assemblies at the envelope are given special attention since it is here that a building’s performance and urban expression are most closely intertwined.

title	Using Tensegrity and Folding to Generate Soft Responsive Architectural Skins
doi	https://doi.org/10.52842/conf.ecaade.2016.1.529
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 1, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 529-536
summary	This paper describes the process of designing a prototype for a soft responsive system for a kinetic building facade. The prototype uses lightweight materials and mechanisms to generate a building facade skin that is both soft (less dependent on hard mechanical systems) and responsive (dynamically and simultaneously adapting to spatial and environmental conditions). By combining concepts stemming from both tensegrity structures and folding mechanisms, we develop a prototype that changes dynamically to produce varying facade patterns and perforations based on sensor-network data and feedback. We use radiation sensors and shape memory alloys to control the prototype mechanism and allow for the required parametric adaptation. Based on the data from the radiation sensors, the lengths of the shape memory alloys are altered using electric wires and are parametrically linked to the input data. The transformation in the resulting overall surface is directly linked to the desired levels of daylighting and solar exposure. We conclude with directions for future research, including full scale testing, advanced simulation, and multi-objective optimization.

title	Material Active Geometry - Constituting Programmable Materials for Responsive Building Skins

summary	This paper is part of a body of research developing an exploratory dialogue between the built form and the environment, via experimentation with performative geometry and material. Here, geometry is considered a design material with the specific capacity to contribute to the performative aspects and kinetic capabilities of building skins.This work opens with a review of emerging opportunities for architects to design materials. It then discusses the concept of Material Active Geometry (MAG) as a means of designing new properties for existing materials. This is followed by a discussion of MAG principles that inform the concepts of flexibility and rigidity in a 3D-printed textile called Flexible Textile Structure (FTS). This research characterizes two FTS types and discusses their potential to be employed in building skins; it also considers combinatory approaches to computational models and physical prototyping. The work concludes with a discussion of the advantages of using FTS, and provides a trajectory for future research in the field of responsive materials and systems.

summary	The term "Parametricism" widespread mainly by Patrick Schumacher (Schumacher, 2008) is worthy of study. Developing the concept of Human Oriented Parametric Architecture, the need of implementing time as the lost parameter in current adaptive design techniques will be discussed. Morphogenetic processes ideas will be discussed through the principle of an adaptable membrane as a case study. A model implementing a unique Arduino[i] on the façade will control its patterns performance through an Artificial Neural Network that will understand the kind of scenario the building is in, activating a Genetic Algorithm that will optimize the insulation performance of the ETFE pillows. The system will work with a global behavior for façade pattern performance and with a local one for each pillow, giving the option of individual sun-shading control. Machine learning implementation will give the façade the possibility to learn from the efficacy of its decisions through time, eliminating the need of a general on-off behavior.

summary	Formeta:3D is a project that engages the posthuman through the development of a machine that translates inputs from its surroundings into physical form in real-time. By responding to interaction with the inhabitants of its environs and incorporating the detected activity in the inflections of the produced form, it has an impact on the activity in the space, resulting in a recursive feedback loop that incorporates the digital, the physical, and the experiential. This paper presents the development of this project in detail, providing a methodology and toolchain for implementing real-time interaction with additive physical form derived from digital inputs and examining the results of an interactive installation set up to test the implementation.

title	An Investigation on Growth Behaviour of Mycelium in a Fabric Formwork

summary	Most progress in designing mycelium-based material to date has been made by using petri dish and 3d printed geometries. In this study, reshaping capabilities of mycelium-based materials using fabric formwork is being discussed. This ongoing study is the result of a series of experiments about mycelium-based material that aims to investigate its potentials as free- form geometry. In this paper, we aim to make a comparison between initial and end shapes by implementing digital and analogue tools based on mycelium-based fabric formwork experiment. The physical experiment setup consists of different initial geometry alternatives and the deformation will be observed and measured numerically by time-based recording on top and section views. With the help of digital tools, experiments will be documented as a process of formation. We aim to discuss the potential of the usage of mycelium as a binding agent in free form geometry since mycelium acts as natural self-assembling glue. By doing so, structural potentials of the material, which is strengthened by mycelium hyphae, were examined. This study aims to contribute to the design research studies and scientific knowledge together to integrate living systems into the material design as encouraging collaborative interdisciplinary research, thereby positioning designer as a decision-maker from the very beginning of material design process.

title	Implementing the General Theory for Finding the Lightest Manmade Structures Using Voronoi and Delaunay
doi	https://doi.org/10.52842/conf.ecaade.2017.2.241

summary	In previous efforts, the foundation of a general theory that searches for finding lightest manmade structures using the Delaunay diagram or its dual the Voronoi diagram was set (Ezzat, 2016). That foundation rests on using a simple and computationally cheap Centroid method. The simple Centroid method is expected to play a crucial role in the more sophisticated general theory. The Centroid method was simply about classifying a cloud of points that represents specific load case/s stresses on any object. That classification keeps changing using mathematical functions until optimal structures are found. The point cloud then is classified into different smaller points' groups; each of these groups was represented by a single positional point that is related to the points' group mean. Those representational points were used to generate the Delaunay or Voronoi diagrams, which are tested structurally to prove or disprove the optimality of the classification. There was not a single optimized classification out of that process but rather a family of them. The point cloud was the input to the centroid structural optimization, and the family of the optimized centroid method is the input to our proposed implementation of the general theory (see Figure 1). The centroid method produced promising optimized structures that performed from five to ten times better than the other tested variations. The centroid method was implemented using the two structural plugins of Millipede and Karmaba, which run under the environment of the Grasshopper plugin. The optimization itself is done using the grasshopper's component of Galapagos.

title	An Algebraic Approach to Implementing a Shape Grammar Interpreter

summary	Shape grammars come in a variety of forms. Algebras of shapes have been defined for spatial elements of different kinds, as well as for shapes augmented with varying attributes, allowing for grammar forms to be expressed in terms of a direct product of basic algebras. This algebraic approach is extended here to the algebraic derivation of combinations of basic shape algebras with attribute algebras. This algebraic abstraction at the same time serves as a procedural abstraction, giving insights into the modular implementation of a general shape grammar interpreter for different grammar forms.

title	Toward the wind-related building performative design

summary	The integration of optimization algorithms and building performance simulation tools make it possible to carry out performa- tive design or performance-driven design, which aims to guide the de- sign synthesis process of the simulation results to continuously im- prove the design. However, the associated research work of wind- related building performance is still deficient, resulting from lack of applicable interface and the time consumption. Meanwhile, in the in- dustrial design realm, the aero-dynamics or fluid-dynamics behaviour of the production under development has been vastly analysed and op- timized based on the multi-discipline optimization (MDO) techniques. Owing to offering numerous built-in interface and integrated optimi- zation algorithm, MDO application software has begun to be used in building optimization design with the complex relationship between various objectives. With the advantage of MDO tools and aimed to provide an efficient optimization approach from the perspective of ar- chitect, this paper proposes a wind-related building performance op- timization design system integrating Rhinoceros and Fluent based on iSIGHT - a MDO application software. In addition, the lighting per- formance is considered in this research as well for implementing the multi-objective optimization. Two case studies of tall building optimi- zation design based on varied generative approaches are introduced to investigate the effect and efficiency of this system.

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	In Brazil, the application of wood in contemporary constructions is concentrated in the south and southeast. However, the entire country has area for cultivation and forest management, which is favorable for expansion in such applications. Wood is capable of absorbing CO2 and consumes little energy in production and manufacturing. During the COVID-19 pandemic, the deficiencies of the building typologies became evident. This research aims to analyze digitally executed prefabricated houses such as Instant House (1), Digitally Fabricated House (2) by Sass, and WikiHouse (3) by Parvin; under the categories of Cardoso (2016): modulation, reversibility, and flexibility. The deductive method was used to investigate assumptions among the three case studies; and grounded in scientific literature to analyze and collect data. In general, the solutions studied enabled customizable systems allied to wood panels, modules, and fittings as generators of architectural form.
