title	Development of Kinetic Facade Units with BIM-Based Active Control System for the Adaptive Building Energy Performance Service
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. 517-526

summary	This paper proposes a novel concept and practice to engage the BIM model as a control system of building energy performance service. This issue can be divided into two sub-issues including the development of more eco-friendly fac?ade which can interact with its local environment, and the related active control system which can process the environmental parameters for eco-friendly actions. This research designs the Parametric Adaptive Skin System (PASS) to en- gage the adaption of natural sunlight use for higher building perfor- mance. PASS consists of kinetic fac?ade components dominated by the BIM-based parametric engine called Dynamo. The PASS prototype demonstrates that the workflows is successful in using a real light sen- sor plus simulated solar terms to drive the interaction of virtual Revit model and physical PASS model.

title	Adaptive Decorative Building Skin
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. 425-434

summary	Traditional decorative ornaments were commonly used on the building skin of traditional architecture. Nowadays in urban areas, those ornaments become less popular for they are considered old- fashioned and due to the lack of technical function that matches with the modern building designs. Based on those issue, this paper pro- posed a type of building skin that aimed to revive a new expression of traditional decorative elements by applying digital design tools and technology as well as having an adaptive function. Traditional decora- tive ornaments merged in an adaptive skin that used traditional pat- terns as a controller of the effect of environmental changes in a build- ing could provide a new expression of the use of traditional ornaments on a building in accordance with the times. Most of the adaptive building skin used kinetic techniques in order to make its formation and pattern transformable. This paper proposed a parametric-cam mechanism to transform the pattern of traditional ornament using pre- programmed analysis data of environmental changes to parametrically drive the number of rotation phase and length of nose that generated the shape of the cams. In conclusion, this paper has developed a proto- typical tool that facilitates the new approach to kinetic decorative or- naments on building skin.

title	Machine Learning Integration for Adaptive Building Envelopes: An Experimental Framework for Intelligent Adaptive Control
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
doi	https://doi.org/10.52842/conf.acadia.2016.098
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	Hybrid Sentient Canopy: An implementation and visualization of proprioreceptive curiosity-based machine learning
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. 362-371
doi	https://doi.org/10.52842/conf.acadia.2016.362
summary	This paper describes the development of a sentient canopy that interacts with human visitors by using its own internal motivation. Modular curiosity-based machine learning behaviour is supported by a highly distributed system of microprocessor hardware integrated within interlinked cellular arrays of sound, light, kinetic actuators and proprioreceptive sensors in a resilient physical scaffolding system. The curiosity-based system involves exploration by employing an expert system composed of archives of information from preceding behaviours, calculating potential behaviours together with locations and applications, executing behaviour and comparing result to prediction. Prototype architectural structures entitled Sentient Canopy and Sentient Chamber developed during 2015 and 2016 were developed to support this interactive behaviour, integrating new communications protocols and firmware, and a hybrid proprioreceptive system that configured new electronics with sound, light, and motion sensing capable of internal machine sensing and externally- oriented sensing for human interaction. Proprioreception was implemented by producing custom electronics serving photoresistors, pitch-sensing microphones, and accelerometers for motion and position, coupled to sound, light and motion-based actuators and additional infrared sensors designed for sensing of human gestures. This configuration provided the machine system with the ability to calculate and detect real-time behaviour and to compare this to models of behaviour predicted within scripted routines. Testbeds located at the Living Architecture Systems Group/Philip Beesley Architect Inc. (LASG/PBAI, Waterloo/Toronto), Centre for Information Technology (CITA, Copenhagen) National Academy of Sciences (NAS) in Washington DC are illustrated.

title	Time in Adaptable Architecture - Deployable emergency intelligent membrane
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 249-258
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.

title	Using the Phase Space to Design Complexity - Design Methodology for Distributed Control of Architectural Robotic Elements

summary	Architecture that is responsive, adaptive, or interactive can contain active architectural elements or robotic sensor-actuator systems. The consideration of architectural robotic elements that utilize distributed control and distributed communication allows for self-organization, emergence, and evolution on site in real-time. The potential complexity of behaviors in such architectural robotic systems requires design methodology able to encompass a range of possible outcomes, rather than a single solution. We present an approach of adopting an aspect of complexity science and applying it to the realm of computational design in architecture, specifically by considering the phase space and related concepts. We consider the scale and predictability of certain design characteristics, and originate the concept of a formation space extension to the phase space, for design to deal directly with materializations left by robot swarms or elements, rather than robots' internal states. We detail a case study examination of design methodology using the formation space concept for assessment and decision-making in the design of active architectural artifacts.

title	Adaptive Pneumatic Shell Structures - Feedback-driven robotic stiffening of inflated extensible membranes and further rigidification for architectural applications
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. 549-558

summary	The paper presents the development of a design framework that aims to reduce the complexity of designing and fabricating free-form inflatables structures, which often results in the generation of very complex geometries. In previous research the form-finding potential of actuated and constrained inflatable membranes has already been investigated however without a focus on fabrication (Otto 1979). Consequently, in established design-to-fabrication approaches, complex geometry is typically post-rationalized into smaller parts and are finally fabricated through methods, which need to take into account cutting pattern strategies and material constraints. The design framework developed and presented in this paper aims to transform a complex design process (that always requires further post-rationalization) into a more integrated one that simultaneously unfolds in a physical and digital environment - hence the term cyber-physical (Menges 2015). At a full scale, a flexible material (extensible membrane, e.g. latex) is actuated through inflation and modulated through additive stiffening processes, before being completely rigidified with glass fibers and working as a thin-shell under compression.

title	Spatial Wire Cutting: Cooperative robotic cutting of non-ruled surface geometries for bespoke building components
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. 529-538
doi	https://doi.org/10.52842/conf.caadria.2016.529
summary	The research project Spatial Wire Cutting (SWC) investi- gates a multi-robotic cutting technique that allows for an efficient production of geometrically complex architectural components. Being pursued by the group of Gramazio Kohler Research at ETH Zurich, this approach involves a spatially coordinated movement of two six- axis robotic arms that control the curvature of a hot-wire, which adopts itself against the resistance of the processed material (e.g. pol- ystyrene). In contrast to standard CNC hot-wire cutting processes, in which the cutting medium remains linear, it allows the automated fab- rication of non-ruled, doubly curved surfaces. This pursuit includes the development of a custom digital design and robotic control framework that combines computational simulation and manufactur- ing feedback information. Ultimately, SWC enables a considerably expanded design and fabrication space for complex architectural ge- ometries and their construction through automated robotic technology. This paper addresses the applied workflow and technology 1) such as computational design and simulation, robotic control and adaptive fabrication, 2) results of application within a two-week design and building workshop, and 3) will conclude with further steps of future research.

title	Protocol of Error: The design and construction of a bending-active gridshell from natural bamboo
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. 415-424
doi	https://doi.org/10.52842/conf.caadria.2016.415
summary	This paper advocates alternative methods to overcome the impossibility of realising ‘perfect’ digital designs. It discusses Hong Kong’s 2015 ‘ZCB Bamboo Pavilion’ as a methodological case study for the design and construction of architecture from unprocessed natu- ral bamboo. The paper critically evaluates protocols set up to deal with errors resulting from precise digital design systems merging with inconsistent natural resources and onsite craftsmanship. The paper starts with the geometric and tectonic description of the project, illus- trating a complex and restrictive construction context. Bamboo’s unique growth pattern, structural build-up and suitability as a bending- active material are discussed and Cantonese bamboo scaffolding craftsmanship is addressed as a starting point for the project. The pa- per covers protocols, construction drawings and assembly methods developed to allow for the incorporation and of large building toler- ances and dimensional variation of bamboo. The final as-built 3d scanned structure is compared with the original digital model. The pa- per concludes by discussing the necessity of computational architec- tural design to proactively operate within a field of real-world inde- terminacy, to focus on the development of protocols that deal with imperfections, and to redirect design from the virtual world towards the latent opportunities of the physical.

title	Painterface: An integrated responsive architectural interface

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	Crowdthinking
source	SIGraDi 2016 [Proceedings of the 20th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Argentina, Buenos Aires 9 - 11 November 2016
summary	The topic "Crowdthinking" reveals the inquiries of researchers about collaborative work, distributed intelligence and collective research. The call focuses on transdisciplinary thinking as a construct based on multiplicity and diversity. All these topics are essential not only in the field of design and architecture, but also in emerging areas of human sciences and arts . Currently, the collaborative design is considered one of the key bases for change in the city and society. In its genesis, it manifests the notion that the world around us is inadequate for many of the needs of the society and from that design can be collectively improved. Such collective research, by combining distributed intelligence, sustainable social development, design cutting edge research, theories and computational strategies, generates a research partnership based on participation and distributed cognition of complex problems. This call proposes an approach in which the results of the experiences can build a model, define or apply axioms and lead to applications. It also looks for emerging conjectures about the process, the creation of computer models and the behaviour of the resulting designs. On the other hand, the need to find solutions that improve the quality of life for the community and sustainable development includes concerns about the integration of the physical and cultural context of cities, mass education and the inclusion of parametric design, digital manufacturing and digital prototyping, and BIM as a system that organizes and ensures the correspondence between the physical urban design and sustainable archetypes. These are some of the concerns in which technology has been contributing to improve the design process by integrating information. This integration optimizes resources and enables the various project professionals to work on the same model, run simulations, improve materializations and evaluate massive amount of data. Projects with greater social and environmental responsibility can be achieved adopting into the teaching and practice this new way of design that anticipates an extensive exchange that wilt foster self-evaluation and reformulation of educational paradigms.

summary	Digital fabrication processes and technologies are becom- ing an essential part of the modern product manufacturing. As the use of 3D printing grows, potential applications into large scale processes are emerging. The combined methods of computational design and robotic fabrication have demonstrated potential to expand architectur- al design. However, factors such as material use, energy demands, du- rability, GHG emissions and waste production must be recognized as the priorities over the entire life of any architectural project. Given the recent developments at architecture scale, this study aims to investi- gate the environmental consequences and opportunities of digital fab- rication in construction. This paper presents two case studies of classic building elements digitally fabricated. In each case study, the projects were assessed according to the Life Cycle Assessment (LCA) frame- work and compared with conventional construction with similar func- tion. The analysis highlighted the importance of material-efficient de- sign to achieve high environmental benefits in digitally fabricated architecture. The knowledge established in this research should be di- rected to the development of guidelines that help designers to make more sustainable choices in the implementation of digital fabrication in architecture and construction.

summary	This paper discusses the development of an interactive and a responsive Tangible User-Interface (TUI) for parametric and Building Information Modeling (BIM) applications. The prototypes presented in this paper utilizes physical computing systems to establish a flexible and intuitive method to engage digital design processes.The prototypes are hybrid UIs that consist of a digital modeling tool and an artifact. The artifact consists of a control system (sensors, actuators, and microcontrollers) and physical objects (architectural elements). The link between both environments associates physical objects with their digital design information to assist users in the digital design process. The integration of physical computing systems will enable the objects to physically respond to analog input and provide real-time feedback to users. The research aims to foster tangible computing methods to extend the capabilities of digital design tools. The prototypes demonstrate a method that allows architects to simultaneously interact with complex architectural systems digitally and physically.

summary	This research documents our initial experiences of using a new type of collaborative, industrial robot in the area of architecture, design, and construction. The KUKA LBR-iiwa differs from common robotic configurations in that it uses seven axes with integrated force-torque sensors and can be programmed in the Java programming language. Its force-sensitivity makes it safe to interact with, but also enables entirely new applications that use hand-guiding and utilize the force-sensors to compensate for high tolerances on building sites, similar to how we manually approach assembly tasks. Especially for the creative industry, the Java programming opens up completely new applications that would have previously required complex bus systems or industrial data interfaces. We will present a series of realized projects that showcase some of the potential of this new type of collaborative, safe robot, and discuss the advantages and limitations of the robotic system.

title	Catenary Wooden Roof Structures: Precedent knowledge for future algorithmic design and construction optimisation

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	Generative Design (GD) is a valuable asset for architecture because it provides opportunities for innovation and improvement in the design process. Despite its availability for Computer-Aided De- sign (CAD), there are few applications of GD within the Building In- formation Modelling (BIM) paradigm, and those that exist suffer from portability issues. A portable program is one that will not only work in the application it was originally written for, but also in others with equivalent results. This paper proposes a solution that explores porta- ble GD in the context of BIM. We also propose a set of guidelines for a programming methodology for GD, adapted to the BIM paradigm. In the end, we evaluate our solution using a practical example.

title	Breathing skins for wind modulation through morphology

summary	This study aims to investigate the design power to manipu- late the behaviour and characteristics of air through geometrical ma- nipulation of building skins. The simple cubic cells in the global sys- tem of a porous screen were manipulated to investigate the impacts of screen’s morphology on the air movement pattern within and around it. The results we discovered from the evaluation of several screen systems revealed trends in response to the careful manipulation of ef- fective shape parameters within a designed matrix of variations as a Matrix of Possible Effective Typologies (MPET). In this research, the main principles of framing the initial matrix were based on: a) Creat- ing pressure differences across the screens as a result of surface intru- sion and extrusion compositions. b) Changing the nature of the airflow (velocity and turbulence variation) with geometrical manipulations of the inlet and outlet of the screens’ components. Experimental and nu- merical studies were undertaken in parallel including the use of a wind tunnel with very smooth flow with precision wind sensors and the numerical studies by Computational Fluid Dynamics. The aim of this paper is to present part of the empirical investigations to demonstrate the power of geometry in shaping the air patterns, altering pressure and velocity through geometrical modification of porous surfaces for future applications.

title	Parametric 3d wind loading on hemispheric dome structures
source	SIGraDi 2016 [Proceedings of the 20th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Argentina, Buenos Aires 9 - 11 November 2016, pp.638-644
summary	Within the visual programming platforms in parametric design, it has not yet available with effective integration the CFD (Computational Fluid Dynamics) simulation systems. This coupling would be particularly useful in relation to the modeling of structures subjected to wind loads in a parametric and algorithmically programmed scenario. It is proposed in this work a parametric modeling of the distribution of wind loads on the surface of a hemispherical dome structure surface. From a combination of wind speed, internal and external pressure coefficient, dimensions of the building, topography and roughness of the terrain. It were defined the magnitude and direction of a field of distributed normal forces on the surface of the hemispherical dome and some results were obtained.
