summary	Architectural surfaces constantly emit radiant heat fluxes to their surroundings, a phenomenon that is wholly dependent on their geometry and material properties. Therefore, the capacity of 3D scanning techniques to capture the geometry of building surfaces should be extended to sense and capture the surfaces’ thermal behavior in real time. We present an innovative sensor, SMART (Spherical-Motion Average Radiant Temperature Sensor), which captures the thermal characteristics of the built environment by coupling laser geometry scanning with infrared surface temperature detection. Its novelty lies in the combination of the two sensor technologies into an analytical device for radiant temperature mapping. With a sensor-based dynamic thermal-surface model, it is possible to achieve representation and control over one of the major factors affecting human comfort. The results for a case-study of a 3D thermal scan conducted in the recently completed Lewis Center for the Arts at Princeton University are compared with simulation results based on a detailed BIM model of the same space.

summary	This paper presents an innovative approach to the design and fabrication of three-dimensional objects from single-piece flat sheets, inspired by the origami technique of twist-closing. While in origami twist-closing is merely used to stabilize a cylindrical or spherical structure, ensuring it maintains its shape, this research investigates the potential of twist-closing as a multi-functional mechanism that also activates and controls the transformation of a planar surface into a predesigned three-dimensional form. This exploration is directed towards an intended application to stiff and brittle sheet materials that are difficult to shape through other processes. The methods we have developed draw mainly upon principles of lattice kirigami and laminar reciprocal structures. These are reflected in a workflow that integrates digital form-generation and fabrication-rationalization techniques to reference and apply these principles at every stage. Significant capabilities of the developed methodology include: (1) achievement of pseudo-double-curvature with brittle, stiff sheet materials; (2) stabilization in a 3D end-state as a frameless self-contained single-element laminar reciprocal structure—essentially a compliant mechanism; and (3) an ability to pre-encode 3D assembly constraints in a 2D cutout pattern, which guides a moldless fabrication process. The paper reviews the precedent geometric techniques and principles that comprise this method of 3D surface fabrication and describes a sample deployment of the method as applied to the design of laminar modules made of high-pressure laminate (HPL).

title	Spatial Glass Bonds - Computation and fabrication system of complex glass structure
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 2, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 251-258

summary	This paper introduces an adaptive robotic spatial aggregation system for the development of an intricate self-supporting glass structure. Rather than using discrete and standardized building elements in the design and fabrication process, this research focuses on utilizing a non-arbitrary shape as an aggregated material for autonomous robotic assembly. More specifically, this paper presents an adaptive robotic fabrication pipeline that measures the size of hollow glass balls (inaccurate materials) as fabrication units to aggregate the entire glass structure. Ultraviolet (UV) curing adhesive is used as the bond between each glass element. Thus, through the live robotic programming as well as various combinations of spherical glass objects and UV curing adhesives/devices, the entire glass structure is self-supported. The project is aimed not only at the development of algorithms and a robotic fabrication system, but also the exploration of the aesthetics of glass materials. In other words, this project investigates a flexible and adaptable framework in response to live sensor data for the design and fabrication of nonstandard spatial structures aggregated out of discrete spherical glass elements, and it further explores glass material aesthetic and perception of architecture.

title	ViBe (Virtual Berlin) - Immersive Interactive 3D Urban Data Visualization - Immersive interactive 3D urban data visualization
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 83-90

summary	The project investigates the possibility of visualizing open source data in a 3D interactive virtual environment. We propose a new tool, 'ViBe'. We programmed 'ViBe' using Unity for its compatibility with HTC VIVE glasses for virtual reality (VR). ViBe offers an abstract visualization of open source data in a 3D interactive environment. The ViBe environment entails three main topics a) inhabitants, b) environmental factors, and c) land-use; acting as representatives of parameters for cities and urban design. Berlin serves as a case study. The data sets used are divided according to Berlin's twelve administrative districts. The user immerses into the virtual environment where they can choose, using the HTC Vive controllers, which district (or Berlin as a whole) they want information for and which topics they want to be visualized, and they can also teleport back and forth between the different districts. The goal of this project is to represent different urban parameters an abstract simulation where we correlate the corresponding data sets. By experiencing the city through visualized data, ViBe aims to provide the user with a clearer perspective onto the city and the relationship between its urban parameters. ViBe is designed for adults and kids, urban planners, politicians and real estate developers alike.

title	The Architecture of ScarCity Game - The craft and the digital as an alternative design process
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 45-52
doi	https://doi.org/10.52842/conf.ecaade.2019.3.045
summary	The Architecture of ScarCity Game is a board game used as a pedagogical tool that challenges architecture students by involving them in a series of experimental design sessions to understand the design process of scarcity and the actual relation between the craft and the digital. This means "pragmatic delivery processes and material constraints, where the exchange between the artisan of handmade, representing local skills and technology of the digitally conceived is explored" (Huang 2013). The game focuses on understanding the different variables of the crafted design process of traditional communities under conditions of scarcity (Michel and Bevan 1992). This requires first analyzing the spatial environmental model of interaction, available human and natural resources, and the dynamic relationship of these variables in a digital era. In the first stage (Pre-Agency), the game set the concept of the craft by limiting students design exploration from a minimum possible perspective developing locally available resources and techniques. The key elements of the design process of traditional knowledge communities have to be identified (Preez 1984). In other words, this stage is driven by limited resources + chance + contingency. In the second stage (Post-Agency) students taking the architects´ role within this communities, have to speculate and explore the interface between the craft (local knowledge and low technological tools), and the digital represented by computation data, new technologies available and construction. This means the introduction of strategy + opportunity + chance as part of the design process. In this sense, the game has a life beyond its mechanics. This other life challenges the participants to exploit the possibilities of breaking the actual boundaries of design. The result is a tool to challenge conventional methods of teaching and leaning controlling a prescribed design process. It confronts the rules that professionals in this field take for granted. The game simulates a 'fake' reality by exploring in different ways with surveyed information. As a result, participants do not have anything 'real' to lose. Instead, they have all the freedom to innovate and be creative.

title	Intelligent Generation of Architectural layout inheriting spatial features of Chinese Garden Based on Prototype and Multi-agent System - A Case Study on Lotus Teahouse in Yixing
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 1, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 291-300
doi	https://doi.org/10.52842/conf.caadria.2019.1.291
summary	This study presents an approach for the intelligent generation of architectural layout, in which partial space inherits Chinese garden spatial features. The approach combines spatial prototype analysis and evolutionary optimization process. On one hand, from the perspective of shape grammar, this paper both analyzes and abstracts the spatial prototype that describes the spatial characteristics of Chinese gardens, including the organization system of architecture and landscape, with the spatial sequences along the tourism orientation. On the other hand, taking the design task of Lotus teahouse as an example, a typical spatial prototype is selected to develop the generative intelligent experiment to achieve the architectural layout, in which the spatial prototype is inherited. Through rule-making and parameter adjustment, the spatial prototype will eventually be transformed into a computational model based on the multi-agent system. Hence, the experiment of intelligent generation of architectural layout is carried out under the influence of the function, form and environmental factors; and a three-dimensional conceptual model that inherits the Chinese garden spatial prototype is obtained ultimately.

summary	This paper presents the results of usability tests of HOPLA (Home Planner), a computer-assisted design system developed to enable customization of house designs. The study aimed to verify whether the proposed method allows non-expert users to configure a house design that meets their expectations in a limited time. The experiments were carried out in two modes of the tool: M mode - modification of a proposed design and S mode - configuration of a design from scratch. The study encompassed two independent experiments carried out on two continents and examined the impact of cultural differences on the expectations of non-expert users towards computer-assisted customization of single-family houses.

doi	https://doi.org/10.52842/conf.acadia.2019.352
summary	This paper presents a project-based research study in the design studio context, highlighting the use of robotic technology as a “perspective-machine” to create custom spatial readings/experiences through predetermined and controlled static/dynamic views. The early studies of this method—in this paper referred to as Robotically Augmented Imaging (RAI Alpha), enables architects, designers, and students to micro direct the “spatial experience” and atmospheric effects of the project through visual story-telling and in multiscale set-ups ranging from architectural to product and object scale. Demonstrating the contemporary opportunities of imaging and perspective—as an architectural tool to investigate/define the space—RAI Alpha studies the potentials of robotically controlled/manipulated views as a possible new medium for interacting with form, space, architecture, atmosphere, and performance in a scale-free seamless experience and as both a design tool and a product.

title	Toward Discrete Architecture: Automation Takes Command
source	ACADIA 19:UBIQUITY AND AUTONOMY [Proceedings of the 39th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-59179-7] (The University of Texas at Austin School of Architecture, Austin, Texas 21-26 October, 2019) pp. 532-541
doi	https://doi.org/10.52842/conf.acadia.2019.532
summary	This paper describes a framework for discrete computational design and fabrication in the context of automation. Whereas digital design and fabrication are technical notions, automation immediately has societal and political repercussions. Automation relates to industrialization and mechanisation—allowing to historically reconnect the digital while bypassing the post-modern, deconstructivist, or parametric decades. Using a series of built prototypes making use of timber, this paper will describe how the combined technologies of automation and discreteness enable both technical efficiencies and new architectural interest. Both projects are based on timber sheet materials, cut and folded into larger elements that are then assembled into functional structures. Both projects are also fragments of larger housing blocks. Discrete building blocks are presented from a technical perspective as occupying a space in between programmable matter and modular prefabrication. Timber is identified as an ideal material for automated discrete construction. From an architectural perspective, the paper discusses the implications of an architecture based on parts that remain autonomous from the whole.

title	If Only Wood Could Speak... - Explorations in digital fabrication processes based on timber grain and patterns
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 227-234
doi	https://doi.org/10.52842/conf.ecaade.2019.3.227
summary	This paper presents an exploration following wood patterns applied to traditional woodworking techniques such as steam bending and carving. It builds on a digital fabrication process where the patterns that are unique to each wood strip and which constitutes their structural geometry are also used within fabrication processes and applied machinery such as the zund machine. The experiments were done in two series where the earlier set focuses on routing along the wood patterns of thin wood strips and steam bending the different pieces. The second set experimented with carving thick wood strips on passes generated from the extracted patterns. An automated technique based in computer vision and specifically OpenCV was developed using different filters in order to extract the patterns and transfer the results into CAD software where the lines where further manipulated for variable exploration. The results of this study led to a better understanding of wood patterns from a geometrical perspective thus enriching the aesthetic composition of a design while being authentic to the unique nature of each piece of wood.

doi	https://doi.org/10.52842/conf.caadria.2019.2.481
summary	This paper starts by introducing an expression proposed by William J. Mitchell measuring the "complexity" of a designed and constructed architectural project. After reviewing other interpretations of this term, as well as specific peculiarities from the building industry, the article expands this metric from an organisational and technological perspective. This is followed by the case studies of six non-standard faÃ§ades whose process complexities are driven by their project-specific affordances. By comparing built projects of different architects and implementation environments, the paper suggests specific criteria for non-standard architectural designs. Application of acquired knowledge has the potential to help architects better control their project's design and construction solution space.

doi	https://doi.org/10.52842/conf.ecaade.2019.2.619
summary	Digital technologies have recently been at the forefront of the causal link between making and design. A growing number of architecture programs of universities incorporates fabrication to the educational environment, and even to the curriculum. Fabrication technology is now considered among the set of tools students are expected to acquire a basic knowledge of and skills in. Nevertheless, the pedagogical potential of fabrication in communicating traditions of making is underused in an oversight of the continuity of the relevant know-how. Our position is that traditions of making can be the subject matter of fabrication with the objective to remedy the role of fabrication tools in architectural history, sustainable architectural production, and in the field of digital heritage. In this paper, we report on two comparative studies that illustrate how the instrumental factors of two historical crafts can be articulated using fabrication.

doi	https://doi.org/10.52842/conf.acadia.2019.458
summary	By introducing rapid reproduction, algorithms, and complex formal configurations, the digital era of architecture began a revolution. Architects incorporated the computational capacity of the computer into the design process both as a tool and as a critical component of the theories and practice of architecture as a whole. As we move into what has been coined “the second digital turn,” a period in which digital integration is considered ubiquitous, how can we consider, prepare, and propel towards the next technological innovation to significantly inform design thinking, representation, and manifestation? What tools are available to investigate this speculative design future and how can they be implemented? If the integration of technology in architecture is now a given, perhaps the next digital design era is not just digital but virtual. As new technologies emerge the potential for integrating the virtual design world with our physical senses affords novel possibilities for interactive design, simulation, analysis and construction. Hybrid reality technologies including virtual reality (VR) and augmented reality (AR), embody the potential to supersede conventional representation methodologies such as drawing, rendering, physical modeling, and animation. As they become increasingly pervasive, they will transform how we communicate ideas and data as spatial concepts. Further, they will reform the construct of the built environment when applied to both materiality and fabrication. This paper will describe the incorporation of VR as a tool in various classroom and laboratory settings, recognize the educational outcomes of this incorporation, and identify the potential relationship of these technologies to future academic exploration and application to practice.

title	Visualise Energy Saving Potentials in Settlement Development: By linking transport and energy simulation models for municipal planning

doi	https://doi.org/10.52842/conf.ecaade.2024.2.079
summary	To achieve Sustainable Development Goals, in addition to the switch to sustainable energy sources and energy-efficient buildings, transport offers a major lever for reducing energy consumption and greenhouse gases. The increasing demand for emission-free mobility (e.g. through electromobility) but also heat pumps has a direct impact on the electricity consumption of buildings and settlements. It is still difficult to simulate the effects and interactions of different measures as sector coupling concepts require comprehensible tools for ex ante evaluation of planning measures at the community level and the linking of domain-specific models (energy, transport). Using the municipality of Bruck an der Leitha (Austria) as an example, a digital twin based on an open data model (Bednar et al., 2020) is created for the development of methods, which can be used to simulate measures to improve the settlement structure within the municipality. Forecast models for mobility (Schmaus, 2019; Ritz, 2019) and the building stock are developed or applied and linked via the open data model to be able to run through development scenarios and variants. The forecasting and visualisation options created in the project form the basis for the ex-ante evaluation of measures and policies on the way to a Positive-Energy-District. By identifying and collecting missing data, data gaps are filled for the simulation of precise models in the specific study area. A digital, interactive 3D model is created to examine the forecast results and the different scenarios.

summary	This paper presents a strategy for implementing computational methods in education to solve specific project related research challenges. In our case, we investigate novel solutions for Organic Photovoltaic Carrier Systems. Therefore, environmental forces (especially the sun and shade) are important design drivers in all projects. Whilst the individual projects are limited to one semester, it is our aim to advance and accumulate these patches within a longer-term research strategy. Especially design-build projects that include digital fabrication often require a skillset not always available in a design studio environment. Providing simple parametric patches frees up time for creative investigations and allows tackling projects that are more complex. In the following, we will present and discuss a series of patches developed over the course of five projects that became our case studies. We conclude, by identifying relevant aspects that might be generalized and evaluate our insights for others.

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	Excessive use of aggregate materials and metals in construction should be balanced by increasing use of construction materials from annually renewable resources based on natural lignocellulosic fibers. Parametric design tools gave here a possibility of using an alternative newly developed biocomposite material, for realization of complex geometries. Contemporary digital fabrication tools have enabled precise manufacturing possibilities and sophisticated geometry-making to take place that helped in obtaining high structural behavior of the overall global geometry of the discussed project. This paper presents a process of realizing an experimental structure made from Natural Fiber-Reinforced Polymers (NFRP)- also referred to as biocomposites, which were synthesized from lignocellulosic flexible core reinforced by 3D-veneer layers in a closed-moulding vacuum-assisted process. The biocomposite sandwich panels parameters were developed and defined before the final properties were imbedded in the parametric model. This paper showcases the multi-disciplinarity work between architects, structural engineers and material developers. It allowed the architects to work on the material development themselves and enabled to apply a new created design philosophy by the first author, namely applying ‘Materials as a Design-Tool’. The erected biocomposite segmented shell construction allowed a 1:1 validation for the whole design process, material development and the digital fabrication processes applied. The whole development has been reached after merging an ongoing industrial research project results with academic education at the school of architecture in Stuttgart-Germany.

summary	This research based on education digs on the "evolution" of Chilean social housing between the period from 70's to 90's asking us the "phylogenic" relation between "typos" of designs that developed several problems in the urban fabric development during 20 years of intricate design just thinking in quantity but not quality in our country.The focus in this research is as the first step understanding the design behind dwellings between this time range, then its process of evolution and transformation by users, and then by BIM understand the virtues and defects of each design and rethink the typologies in a housing life cycle look for the next years.
