title	Parametrically Fabricated Joints: Creating a Digital Workflow
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.412-417
summary	Timber joinery for furniture and architectural purpose has always been identified as a skill or craft. The craft is the demonstration of hand machined skill and precision which is passed down or developed through the iteration of creation and refined reflection. Using digital fabrication techniques provides new, typically unexplored ways of creating and designing joints. It is as if these limitations which bind the ratio of complexity and use are stretched. This means that these joints, from a technical standpoint, can be more advanced than historically hand-made joints as digital machines are not bound by the limitations of the human. The research investigated in this paper explores the ability to create sets of joints in a parametric environment that will be produced with CNC machines, thus redefining the idea of the joint through contemporary tools of creation and fabrication. The research also aims to provide a seamless, digital workflow from the flexible, parametric creation of the joint to the final physical fabrication of it. Traditional joints, more simple in shape and assembly, were first digitally created to ease the educational challenges of learning a computational workflow that entailed the creation and fabrication of geometrically programmed joints. Following the programming and manufacturing of these traditional joints, more advanced and complex joints were created as the understanding of the capabilities of the software and CNC machines developed. The more complex and varied joints were taken from a CAD virtual environment and tested on a 3-axis CNC machine and 3D printer. The transformation from the virtual environment to the physical highlighted areas that required further research and testing. The programmed joint was then refined using the feedback from the digital to physical process creating a more robust joint that was informed by reality.

title	Bric(k)olage: Spoliated Masonry C+D Waste
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 3: Proceedings of the 43rd Annual Conference for the Association for Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9891764-1-0]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 24-32.
summary	The 2016 US Environmental Protection Agency reported that 23.1 million tons of broken pieces of concrete waste are annually discarded from new construction sites (EPA -2) and in example states in the north american context only 6.6% of C&D concrete is recycled; the rest is thrown out in landfills as it is labeled “contaminated or too hard to process on a large scale.” (CT DOE 25) Relatively little investigation has occurred in how this material could reappear in the architectural project that might honor its intrinsic broken quality as a part of its materiality within a life-cycle of continual usage. This project speaks towards a problematic Habit of the Anthropocene in how we construct buildings placing intrinsic cultural value on new parts over the broken and old due to economic efficiencies.

title	Micro-scale weather data for energy performance assessment in Singapore
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. 229-238

summary	Weather data plays an important role for energy perfor- mance assessment in the design of buildings and urban environments. Many researches have been carried out to generate and analyse vari- ous weather files for different simulation platforms. However, investi- gations have been lacking in the development of weather files that ac- count for urban heat island (UHI) problems. As a result of global warming and the complexity of the urban environment, the weather file for a modern city cannot be simply based on climate information from 20 years ago. The objective of this research is to demonstrate a method for creating different micro-scale typical meteorological year (TMY) weather files based on different urban texture values. This re- search includes three steps: 1) Recent years weather data is obtained. 2) Considering the UHI impact, a series of new TMY weather files are generated for different micro-scale areas in Singapore based on rele- vant urban texture variables. 3) A comparison of the results shows that there is a big difference between the new and the old TMY. The tem- perature of the new TMY is 1-2°C higher, while the solar radiation is lower than the original TMY data. Hence the new weather files will be more credible than the original TMY for energy performance simula- tion in the design process.

title	Enhance Architectural Heritage Conservation Using BIM Technology
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. 477-486

summary	Common problems tend to surface during the restoration and maintenance of wooden structures for architectural heritage: (1) recording and communicating geometric and non-geometric infor- mation, (2) integrating and managing the multiple phases of construc- tion and (3) the structural damage that can be incurred during the dis- mantling process. This leads to less confidence in the quality of restoration and maintenance. This study considers the traditional wooden structures in Taiwan as a basis to discuss the issues faced dur- ing restoration and the gap in communication between designers and builders. Using new techniques, resources and the concept of BIM, a plugin is developed for guiding restoration. It serves as a BIM-based communication platform for designers and builders, enabling the real- time exchange of information to minimise any gaps that may exist be- tween the designers’ information and that of the builders. This allows information related to the restoration to be more accurate and offers the assurance that the traditional architecture retains its original struc- ture and value.

title	Living on the Edge - Reinventing the amphibiotic habitat of the Mesopotamian Marshlands
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. 513-526
summary	The Mesopotamian Marshlands form one of the first landscapes where people started to transform and manipulate the natural environment in order to sustain human habitation. For thousands of years, people have transformed natural ecosystems into agricultural fields, residential clusters and other agglomerated environments to sustain long-term settlement. In this way, the development of human society has been intricately linked to the extraction, processing and consumption of natural resources. The Mesopotamian Marshlands, located in one of the hottest and most arid areas on the planet, formed a unique wetlands ecosystem, which apart from millions of people, sustained a very high number of wildlife and endemic species. Several historical, political, social and climatic changes, which densely occurred during the past century, completely destroyed the unique civilisation of the area, made all the wild flora and fauna disappear and forced hundreds of thousands of people to migrate. During the last decade, many efforts have been made to restore the marshlands. However, these efforts are lacking a comprehensive design strategy, coherent goals and deep understanding of the complex current geopolitical situation, making the restoration process an extremely difficult task. This work aims at providing strategies for recovering the Mesopotamian Marshlands, organising productive functions in order to sustain the local population and design a new inhabitation model, using advanced computational tools while taking into account the extreme climatic conditions and several unique cultural aspects. Part of the aim of this work is to advance the use of computation and explore the opportunities that digital tools afford in helping find solutions to complex design problems where various design variables need to be coordinated to satisfy the design goals. Today, advanced computation enables designers to use population consumption demands, ecological processes and environmental inputs as design parameters to develop more robust and resilient regional planning strategies. This work has the double aim of first, presenting a framework for re-inhabiting the Marshlands of Mesopotamia. Second, the work suggests a design methodology based on computer-aided design for developing and organising productive functions and patterns of human occupation in wetland environments.

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.

summary	The paper details the computational modelling work to define a new type of responsive material system based on genetically engineered bacteria cells. We introduce the discipline of synthetic biology and show how it may be possible to program a cell to respond genetically to inputs from its environment. We propose a system of synthetic biocementing, where engineered cells, living within a soil matrix, respond to pore pressure changes in their environment when the soil is loaded by synthesising new material and strengthening the soil. We develop a prototype CAD system which maps genetic responses of individual bacteria cells to geotechnical models of stress and pore pressure. We show different gene promoter sensitivities may make substantial changes to patterns of consolidation. We conclude by indicating future research in this area which combines both in vivo and in silico work.

title	Understanding Intangible Cultural Landscapes - Digital tools as a medium to explore the complexity of the urban space
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. 431-436
summary	The cultural heritage landscape (CHL) of the urban space in cities is the result of multiple layers of complexity, encompassing both the tangible built environment and intangible cultural values that together influence the living heritage that forms the spirit of place. This paper explores the gap in the intangible and living heritage documentation of CHLs by using a section of public space in the medieval historic centre of Bologna, Italy. Digital technology is used to propose a new paradigm in the study of the complex link between the tangible, intangible and living cultural heritage, co-existing in public spaces of a city’s cultural heritage landscape.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
summary	A research team at Florida International University Robotics and Digital Fabrication Lab has developed a novel method for 3d-printing curved open grid core sandwich structures using a thermoplastic extruder mounted on a robotic arm. This print-on-print additive manufacturing (AM) method relies on the 3d modeling software Rhinoceros and its parametric software plugin Grasshopper with Kuka-Parametric Robotic Control (Kuka-PRC) to convert NURBS surfaces into multi-bias additive manufacturing (MBAM) toolpaths. While several high-profile projects including the University of Stuttgart ICD/ITKE Research Pavilions 2014–15 and 2016–17, ETH-Digital Building Technologies project Levis Ergon Chair 2018, and 3D printed chair using Robotic Hybrid Manufacturing at Institute of Advanced Architecture of Catalonia (IAAC) 2019, have previously demonstrated the feasibility of 3d printing with either MBAM or sandwich structures, this method for printing Compound-Curved Sandwich Structures with Robotic MBAM combines these methods offering the possibility to significantly reduce the weight of spanning or cantilevered surfaces by incorporating the structural logic of open grid-core sandwiches with MBAM toolpath printing. Often built with fiber reinforced plastics (FRP), sandwich structures are a common solution for thin wall construction of compound curved surfaces that require a high strength-to-weight ratio with applications including aerospace, wind energy, marine, automotive, transportation infrastructure, architecture, furniture, and sports equipment manufacturing. Typical practices for producing sandwich structures are labor intensive, involving a multi-stage process including (1) the design and fabrication of a mould, (2) the application of a surface substrate such as FRP, (3) the manual application of a light-weight grid-core material, and (4) application of a second surface substrate to complete the sandwich. There are several shortcomings to this moulded manufacturing method that affect both the formal outcome and the manufacturing process: moulds are often costly and labor intensive to build, formal geometric freedom is limited by the minimum draft angles required for successful removal from the mould, and customization and refinement of product lines can be limited by the need for moulds. While the most common material for this construction method is FRP, our proof-of-concept experiments relied on low-cost thermoplastic using a specially configured pellet extruder. While the method proved feasible for small representative examples there remain significant challenges to the successful deployment of this manufacturing method at larger scales that can only be addressed with additional research. The digital workflow includes the following steps: (1) Create a 3D digital model of the base surface in Rhino, (2) Generate toolpaths for laminar printing in Grasshopper by converting surfaces into lists of oriented points, (3) Generate the structural grid-core using the same process, (4) Orient the robot to align in the direction of the substructure geometric planes, (5) Print the grid core using MBAM toolpaths, (6) Repeat step 1 and 2 for printing the outer surface with appropriate adjustments to the extruder orientation. During the design and printing process, we encountered several challenges including selecting geometry suitable for testing, extruder orientation, calibration of the hot end and extrusion/movement speeds, and deviation between the computer model and the physical object on the build platen. Physical models varied from their digital counterparts by several millimeters due to material deformation in the extrusion and cooling process. Real-time deviation verification studies will likely improve the workflow in future studies.

title	Implications of Including Fully Participating Furniture and Fittings in Numerical Simulation Models
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. 237-246
summary	Many simulation teams create models of empty buildings, e.g. without furnishings and fittings. Such virtual worlds lack many of the thermal and visual artefacts by which we make thermal and visual judgements and some numerical tools only abstractly treat the physics of furnishing and fittings. This paper explores what happens if sunlight actually falls on desks and chairs and filing cabinets rather than the floor as well as what happens if interior artefacts were treated with the same rigour as facades by the simulation engine and are available for use in visual assessments. Typically increasing model resolution is a tedious process and added detail if included, may not be fully utilised. To explore removing such barriers, a data store of pre-defined entities, which include provenance, visual form, explicit thermophysical composition, light distributions and mass flow attributes has been introduced in ESP-r. ESP-r facilities for calculating view-factors and insolation distributions have been updated to include this extended data model. Issues related to creating and managing such entities is discussed and the impacts of their use is quantified.

summary	This paper seeks to explore the process of elastic bending in furniture design and presents a case study that demonstrates the creative and structural potential of bending-active structures as possible improvement to the current state of the art. This case study brings together design procedures, borrowed from declarative design in software engineering, architectural design, and material science in order to envision new applications for bending-active structures. It investigates how bending can be used strategically for the design of furniture scale objects and, particularly, an office chaise lounge for one person. Active-bending implementation is the key for creating structures that achieve new milestones beyond the perceived limits of material and process. Moreover, the project stands as a great opportunity for the development of a pipeline for fabrication that automates the translation of a given high-level description of a design, to the production of the data required for fabrication via a particular material system.

summary	The concept of parametric design combines software and 3D modeling application that provides to designers, architects and engineers a new method for design development. This article aims to create a device for bicycle parking aided by a parametrization process using Grasshopper plug-in. Thus, we develop an algorithm in which its parameters can be modified accordingly to the esthetic-formal configuration required by the project. In order to evaluate the effect of a parametric value over the structure and resulting form, a rendering is created with each parameter change to visualize the resulting design interactively.

summary	Since the turn of the millennium, architects and designers have used greater access to Computer Aided Manufacturing (CAM) machines to explore links between design and fabrication. This trend is recently manifested in plug-ins for CAD software packages, which enable designers to program industrial robots and additive manufac- turing machines. However, amongst the array of contemporary tools, few connect CAD packages to commercial 5-axis routers and, as a re- sult, designers are forced to use complex CAM software to operate these machines with limited exploration of the interface with design. This paper reports on the development of a CAD plug-in for driving such routers and targeted at designers. It discusses key aspects in the conception of the software libraries for an alpha release of the tool, a plug-in for McNeel Grasshopper named Termite. Primary considera- tions for the development team include the areas and extent of flexi- bility offered in order to enable non-expert users of such machines to use them to in an effective and efficient manner. Key elements of the tools are discussed, including the definition of machining tools, the creation of generic toolpaths and the subsequent writing machine-code files. A set of example pieces are presented to demonstrate the pro- posed approach for flank-milling, patterning and connecting timber components at a furniture scale. These are compared to plug-ins for industrial robot with similar technical knowledge and experience amongst the target audience.

title	Development of schematic estimation system through linking QTO with Cost DB
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. 507-516

summary	Cost estimate in architectural projects is an important factor for decision-making and financing the project in both early design phase and detailed design phase. In Korea, estimate work based on 2D drawing has generated problems of difference form QTO according to worker’s mistake and know-how. In addition, 2D-based estimation are obtained uncertainty factors of estimation depending on lack of infor- mation due to becoming larger and more complex than any other pro- ject of the architectural project. In order to solve limitations, this study is to suggest an open BIM-based schematic estimation process and a prototype system within the building frame through linking QTO and cost information. This study consists of the following steps: 1) Ana- lysing Level of Detail (LoD) to apply to the process and system, 2) BIM modelling for open BIM-based QTO, 3) Verifying the quality of the BIM model, 4) Developing a schematic estimation prototype sys- tem. This study is expected to improve work efficiency as well as reli- ability of construction cost.

summary	MeasureIt-ARCH is A GNU GPL licensed, dimension, annotation, and drawing tool for use in the open source software Blender. By providing free and open tools for the reading and editing of architectural drawings, MeasurIt-ARCH allows works of architecture to be shared, read, and modified by anyone. The digitization of architectural practice over the last 3 decades has brought with it a new set of inter-disciplinary discourses for the profession. An attempt to utilise 'Open-Source' methodologies, co-opted from the world of software development, in order to make high quality design more affordable, participatory and responsible has emerged. The most prominent of these discussions are embodied in Carlo Raitti and Mathew Claudel's manifesto 'Open-Source Architecture' (Ratti 2015) and affordable housing initiatives like the Wikihouse project (Parvin 2016). MeasurIt-ARCH aims to be the first step towards creating a completely Open-Source design pipeline, by augmenting Blender to a level where it can be used produce small scale architectural works without the need for any proprietary software, serving as an exploratory critique on the user experience and implementations of industry standard dimensioning tools that exist on the market today.

title	Geospatial Tool Evaluating Job Location Mismatch, Based on Available Workforce and Transit Options - Evaluating property location in a city using large-scale datasets
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. 557-566
summary	The paper addresses the issue of spatial mismatch of jobs and the accessibility to job locations based on different age, income and industry group. Taking Atlanta as a case study, we developed a geospatial analysis tool enabling developers, the city planning bureau and the residents to identify potential sites of redevelopment with better economic development opportunities. It also aids to find potential location to live with respect to user’s choices for transit options, walkability, job location and proximity to chosen land use. We built our model on a block level in the city, imparting them a score, visualizing the data as a heat map. The metrics to compute the score included proximity to job, proximity to worker’s residence, transit availability, walkability and number of landmark elements near the site. We worked with Longitudinal Employer-Household Dynamics (LEHD) Data along with residence area characteristics (RAC) and work place area characteristic (WAC) data sets, where the total number of data-points was over 3 million. It was challenging for us to optimize computation such that the prototype performs statistical analysis and updates visualization in real time. The research further is prototyped as a web application leveraging Leaflet’s Open Street Maps API and D3 visualization plugin. The research showed that there is a high degree of spatial mismatch between home and job locations with very few jobs with driving distance within 5 -10 miles with limited transit options in Atlanta. Further, it showed that low-earning workers need to travel significantly larger distance for work compared to higher class.

title	Rigorous Creativity - Ubiquity, Parametrics, Tectonics
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. 3-6
summary	Architects frequently understand and experience design and creativity as a personal and lonely activity. However, there is, increasingly, a need to collaborate with others in the design and construction of buildings. Digital technology is intricately intertwined with the creative and social aspects of the emerging practice world. A prime example is the use of digital fabrication technology and building information models to directly transfer information among architects, contractors, fabricators and consultants. At the same time, the discipline and practice of creative design is increasingly seen as a valuable cognitive skill, to be emulated, tapped, and understood by other disciplines in various settings. Fields outside of architecture and governmental granting agencies have shown strong interest in understanding, rationalizing and importing the creative design process that architects engage in. The obstacle, however, has been that architects and designers are rarely able to explain their processes in a manner understood by others. The advent of digital tools and social computing further complicates the issues of how designers design with such tools and how designers design with others (Lawson, 2005). Our aim should be to define a discipline of collaborative digital design with clear conceptual frameworks, methodologies, and epistemologies. The goal is two-fold: 1) to formulate a discipline of digital design based on sound theoretical and pragmatic underpinnings, and 2) to elucidate the processes of digital design so that we can better communicate them to other disciplines and thus engage more effectively in interdisciplinary research.

summary	The paper presents results of a research conducted in 2015 and 2016 at Lodz University of Technology. It proposes a purpose and context fit approach towards the automation of urban data generation based on GIS tools and New Urbanism typologies. First, background studies of methods applied in urban morphology analysis are revealed. Form-Based Code planning, and subsequently Transect-Based Code are taken into account. Then, selected examples from literature are described and discussed. Finally, the research study is presented and the outcomes compared with more traditional methodology.
