summary Building performance simulation tools have indeed eased the task of evaluating a building’s performance from the point of view of lighting design, heating and cooling loads, total energy loads, acoustic properties, natural lighting, ventilation, smoke and fire containment etc. However, to use these tools correctly, not only is theoretical knowledge required but also insight that can only be attained after substantial experience. For example, in order to evaluate the thermal performance alone, one needs to understand climatology, material properties, building physics, HVAC systems, internal and external gain factors, solar impacts, etc. to name a few. Hence, teaching students of Architecture how to use these tools, and also to interpret the results properly, is a tall order. This paper reports on insights gained through teaching courses on building performance simulations to graduate students in the Department of Architecture. The course content was varied each term and a different simulation software was used; namely: ECOTECT, Energy Plus and Design Builder. Data presented here will also contain feedback from the course students regarding the modelling process of the buildings, inputting the data, simulating their performance, and evaluating the results. Also, the difficulties faced during the various steps as well as the drawbacks of the tools will be discussed in depth.

summary The conference logo is a bird’s eye view of spiral stairs that join and separate – an homage to the famous double spiral staircase in Graz, a tourist attraction of this city and a must-see for any architecturally minded visitor. Carved out of limestone, the medieval construction of the original is a daring feat of masonry as well as a symbolic gesture. The design speaks of separation and reconciliation: The paths of two people that climb the double spiral stairs separate and then meet again at each platform. The relationship between architectural design and the growing digital repertoire of tools and possibilities seems to undergo similar cycles of attraction and rejection: enthusiasm about digital innovations – whether in Virtual Reality, Augmented Reality, Energy Design, Robotic Fabrication, the many Dimensions of BIM or, as right now, in AI and Machine Learning – is typically followed by a certain disillusionment and a realization that the promises were somewhat overblown. But a turn away from these digital innovations can only be temporary. In our call for papers we refer to the first and second ‘digital turns’, a term Mario Carpo coined. Yes, it’s a bit of a pun, but you could indeed see these digital turns in our logo as well. Carpo would probably agree that design and the digital have become inseparably intertwined. While they may be circling in different directions, an innovative rejoinder is always just around the corner. The theme of the conference asked participants to re-consider the relationship between Design and the Digital. The notion of a cycle is already present in the syllable “re”. Indeed, 20 years earlier, in 2003, we held an ECAADE conference in Graz simply under the title “Digital Design” and our re-using – or is it re-cycling? – the theme can be seen as the completion of one of those cycles described above: One level up, we meet again, we’ve come full circle. The question of the relationship between Design and the Digital is still in flux, still worthy of renewed consideration. There is a historical notion implicit in the theme. To reconsider something, one needs to take a step back, to look into the past as well as into the future. Indeed, at this conference we wanted to take a longer view, something not done often enough in the fast-paced world of digital technology. Carefully considering one’s past can be a source of inspiration. In fact, the double spiral stair that inspired our conference logo also inspired many architects through the ages. Konrad Wachsmann, for example, is said to have come up with his famous Grapevine assembly system based on this double spiral stair and its intricate joinery. More recently, Rem Koolhaas deemed the double spiral staircase in Graz important enough to include a detailed model of it in his “elements of architecture” exhibition at the Venice Biennale in 2014. Our interpretation of the stair is a typically digital one, you might say. First of all: it’s a rendering of a virtual model; it only exists inside a computer. Secondly, this virtual model isn’t true to the original. Instead, it does what the digital has made so easy to do: it exaggerates. Where the original has just two spiral stairs that separate and join, our model consists of countless stairs that are joined in this way. We see only a part of the model, but the stairs appear to continue in all directions. The implication is of an endless field of spiral stairs. As the 3D model was generated with a parametric script, it would be very easy to change all parameters of it – including the number of stairs that make it up. Everyone at this conference is familiar with the concept of parametric design: it makes generating models of seemingly endless amounts of connected spiral stairs really easy. Although, of course, if we’re too literal about the term ‘endless’, generating our stair model will eventually crash even the most advanced computers. We know that, too. – That's another truth about the Digital: it makes a promise of infinity, which, in the end, it can’t keep. And even if it could: what’s the point of just adding more of the same: more variations, more options, more possible ways to get lost? Doesn’t the original double spiral staircase contain all those derivatives already? Don’t we know that ‘more’ isn’t necessarily better? In the original double spiral stair the happy end is guaranteed: the lovers’ paths meet at the top as well as when they exit the building. Therefore, the stair is also colloquially known as the Busserlstiege (the kissing stair) or the Versöhnungsstiege (reconciliation stair). In our digitally enhanced version, this outcome is no longer clear: we can choose between multiple directions at each level and we risk losing sight of the one we were with. This is also emblematic of our field of research. eCAADe was founded to promote “good practice and sharing information in relation to the use of computers in research and education in architecture and related professions” (see ecaade.org).

title BIM and Teaching in Architecture: Current thinking and approaches

summary Increasing use of BIM has represented a continuing shift in traditional assumptions on how we navigate the design process. BIM is affording the student the ability to gain a greater understanding of their design ideas via the exploration of scale, spatial organisation and structure, amongst many other design layers, in increasing levels of detail, at the same point in the design process. Architectural education is at a delayed tipping point where architectural students are increasingly looking towards BIM to streamline their design process drawn by the production of realistic visualisation, but with a lack of knowledge and skill in its application. With a lack of guidance and understanding around the application of BIM, the use of BIM in this manner overlooks the potential of BIM to construct and test virtual simulations of proposed schemes, to support design enquiry. A historical concern for the pedagogy constructed around the students’ design process is the application of methods and techniques that support the progression through the design process, (Ambrose, 2014; dash mei & Safari, 2018). This study examines the design process of architectural students and the interaction between analogue and digital methods used in design. These primary modes of communication, offer the opportunity to query the roles and rules of traditional architectural conventions around ‘problem finding’ and ‘problem solving’, challenging the ‘traditional’ design process examined by pioneers like Bruner (1966) and Schon (1987). These approaches are distilled from the findings of the study and presented as guidance to those teaching in architectural aBIMemia to align pedagogic goals to methods of abstraction in this new era of design education reconsidering digital methods in design.

title Sculpting the Space: A Circulation Based Approach to Generative Design in a Multi-Agent System
doi https://doi.org/10.52842/conf.caadria.2014.565
source Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 565–574
summary This paper discusses an MAS (multiagent system) based approach to generating architectural spaces that afford better modes of human movement. To achieve this, a pedestrian simulation is carried out to record the data with regard to human spatial experience during the walking process. Unlike common practices of performance oriented generation where final results are achieved through cycles of simulation and comparison, what we propose here is to let human’s movement exert direct influence on space. We made this possible by asking "humans" to project simulation data on architectural surroundings, and thus cause the layout to change for the purpose of affording what we designate as good spatial experiences. A generation experiment of an exhibition space is implemented to explore this approach, in which tentative rules of such spatial manipulation are proposed and tested through space syntax analyse. As the results suggested, by looking at spatial layouts through a lens of human behaviour, this projection-and-generation method provides some insight into space qualities that other methods could not have offered.

title Evolutionary Algorithms in Islamic Architecture

summary The cosmological nature of Islamic architecture makes it a useful case study for the capability of the adaptation, assimilation and accommodation with the development of evolutionary algorithms and their applications in architectural design. Genetic algorithm derives its structure from the observation of nature. We shall review the concept of intelligent agents and their organization into complex adaptive systems as well as genetic-type algorithms for learning and evolution. Since algorithmic art consists of generation of images on the basis of algorithms, algorithms can be viewed as a notation, and notation is something that music has but visual artefacts in general miss. This paper aims to discover the role of evolutionary algorithms in historical Islamic architecture. Also, we shall try to investigate the way in which the future development could occur not only through the discovery of new facts or theories, but also through the rise and dissemination of new visions having different explanation of Islamic architecture that considers it as a result of serious application of formation through evolutionary genetic algorithms.

summary Governments in Australia are faced with policy implementation that mandates higher energy efficient housing (Foran, Lenzen & Dey 2005). To this effect, the National Construction Code (NCC) 2013 stipulates the minimum energy performance for residential buildings as 114MJ/m2 per annum or 6 stars on an energy rating scale. Compliance with this minimum is mandatory but there are several methods through which residential buildings can be rated to comply with the deemed to satisfy provisions outlined in the NCC. FirstRate5 is by far the most commonly used simulation software used in Victoria, Australia. Meanwhile, Building Information Modelling (BIM), using software such as ArchiCAD has gained a foothold in the industry. The energy simulation software within ArchiCAD, EcoDesigner, enables the reporting on the energy performance based on BIM elements that contain thermal information. This research is founded on a comparative study between FirstRate5 and EcoDesigner. Three building types were analysed and compared. The comparison finds significant differences between simulations, being, measured areas, thermal loads and potentially serious shortcomings within FirstRate5, that are discussed along with the future potential of a fully BIM-integrated model for energy rating certification in Victoria.

summary Skin is the primary shield between our body and its surroundings. It protects the body from the harmful environmental effects like dehydration and radiation from intense sunlight. Likewise, the outer layer, or skin of a building has the same function of protecting its inhabitants against the external elements. This research is a part of a larger investigation into geometrical patterning and layering of facades as an effective intervention between the outdoor space and the indoor environment to regulate the conditions for occupant thermal comfort. This paper reports on exploration of an approach for measurement, evaluation and feedback in the design workflow through a mixed digital -physical simulation platform (MDPS) based on the objectives of the larger study. For this purpose, it introduces a new way of analyzing thermal performance of double skin facades by using temperature sensors, Arduino, post visualization with MATLAB and digital energy simulation. The main aspects of this proposed workflow is the design of a thermal performance feedback loop as an integral part of the process of geometrical patterning design for façade.

title An Automated Value-based Evaluation and Conditional Approval of Construction Submittals
source Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 161-174
summary To ensure compliance with specifications during construction, a formal review process, called the submittals process, is typically used whereby a contractor submits proposals for materials, equipment, and processes for owner’s approval. This evaluation process can be a difficult task because of time restriction, lack of information in the submittal package, and lack of defined criteria for evaluation. This study thus introduces an automated decision support for submittal evaluation that uses the Multi-Attribute Utility Theory (MAUT) to evaluate a submittal considering its impact on the construction and operation of the building. First, key building submittals are analyzed and the top one (chiller) is selected and its evaluation parameters grouped into two categories: non-flexible and flexible. The non-flexible parameters have been dealt with as a checklist with predefined thresholds that must be met without tolerance. Flexible parameters, on the other hand, have been analyzed using utility values that represent decision makers’ preferences and tolerance levels. Accordingly, the evaluation process determines the overall utility for the submittal and the value-based condition for accepting it. An automated prototype system has been developed using data provided by three organizations through intensive interviews with experts. A case study was then used to prove that the proposed evaluation system provides consistent and objective decisions, internal alignment of organizational values, and improved lifecycle performance of submittal items.

summary The need for increased automation of the AEC sector has been extensively documented within the architectural discipline over recent years. Far beyond economic perspectives, current advances in technology offer an increased and more direct implementation of sustainable materials. Within this research, the potential for the re-use of material with low embodied energy within automated construction will be examined. Herefore, Remote Material Deposition (RDM, firstly described in Dörfler et al., 2014) is utilized as main fabrication method, deploying varying compositions of local building debris, lime mortar, and sand, via a throwing arm. This research explores a method of continuous verification of material deployment and removal of material oversaturation to guarantee accuracy. Herefore, all instances of the robot ecology are in direct communication with one another and the user for verification, adaptation, and information. The proposed framework is examined through experimentation by designing, building, and implementing an inter-communicative network of bespoke semi-autonomous robots with all proposed parts of the system.

title Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
doi https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
source Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
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.

summary Building designers make decisions in early design stages that have large impact on building performance, including those of energy-, daylight- and indoor environment performance. Building performance simulation (BPS) tools can support the designer, in making better decisions, by providing the performance consequences of design choices. However BPS tools often require deep technical knowledge and is too time consuming to use to effectively support the design exploration in the early design stages. To solve this challenge, the current paper proposes: Sentient building performance simulation systems, which combine one or more high precision BPS tools to provide near instantaneous performance feedback directly in the design tool. Sentient BPS systems are essentially combining: 1) design tools, 2) parametric tools, 3) BPS tools, 4) dynamic databases 5) interpolation techniques and 6) prediction techniques as a fast and valid simulation system for the early design stage.

title Temporary Architecture: An urban mirage

summary One of the emerging multidisciplinary contemporary art practices is interactive installation art, which is concerned with constructing a temporary artistic environment that is digital, responsive and engaging. It is usually displayed within existing architectural context whether indoor in a gallery space or outdoor in a public space. Recent examples of such art projects show that interactivity and illusion are effectively present and highly influential in the perception and memory of the place. A digital display on a building façade can remain attached to the history of the site in the spectator’s memory even after the display is removed. An interactive space that involves body response and emotional sensory interaction can determine the narrative perceived from the experience. These trends seemingly bring together the physical context and the digital space to contain the spectator. The two mediums are merged to provide a new genre of space, hence a new mode of perception where the art space mediates people’s movement and overlay the context with new meanings. Multiple backgrounds are involved in the creative process of interactive installation art, all of which involve examining various concepts through artistic engagement with temporary spaces. Here, particularly because of interactivity and immerseveness, the spectator becomes part of the performance (the subject); with his moving and reacting he activates the narrative and probably gives it its shape. This paper aims to explore the potentials of the digital spatial display to enhance or weaken our sense of belonging to the surrounding environments while creating an illusionary space within the real physical one. It also aims to discuss how this influence would affect the memory of the mixed experience; the installation being digital, temporary and illusive and the space being physical, permanent and real. What happens to the “spectator” when contained by the digital-interactive and the physical medium(s)?. In order to unfold the mentioned questions, the study uses theories of perception and performance reflected on live case studies of recent art projects where the researcher becomes a member of the audience and an observer at the same time in order to trace the journey inside this new medium. In an era where time is being more difficult to grasp and identities of visual culture is becoming more difficult to define, temporary responsive environments can provide some openings where space becomes durational, yet, influential, and where people’s movements become more meaningful in the visual terrain.

summary Architecture took an evolutionary context over time, where designers were interested in finding pragmatic spontaneous appropriate solutions and met the needs of people in urban and architectural spaces. Whereas, in modern architecture an intense and varied competition happens between architects through various currents of thoughts , schools and movements, however, that creativity was the ultimate goal , and a the same time we find that every architect distinguishes himself individually or collectively through tools of architectural expression and design representation adopting a school of thought, using , for example, the leaves of various sizes and diverse technical drawing tools to accurately show that he can be read by professionals or craftsmen outside the geographical scope to which it belongs .With the rapid technological development which accompanied the digital craft in the contemporary world , The digital craft summed up time, distance and tools , so they gave the concept more appropriate accuracy , as virtualization has become the most effective tool for Architecture To reach the ideal and typical results at the practical level, or pure research. At the level of residential design and on the grounds that housing plays an important role in the government policies and given that housing is a basic unit common to all urban communities on earth , the use of different programs to show its typicality in two dimensions or in the third dimension - for example, using software "AutoCAD " " 3D Max " , " ArchiCAD " ... etc. - gave virtualisation smart, creative and beautiful forms which lead to better understand the used /or to be used residential spaces, and thus the conclusion that the life system of dwelling under design or under study , as can specifically recognize spatial structure in housing design - using digital software applying "Space Syntax" for example - in the shadow of slowly growing digital and creative development with the help of high-speed computers . the morphological structure of the dwelling is considered to be the most important contemporary residential designs Investigation through which the researcher in this area aims to understand the various behavioral relations and social structures within the projected residential area, using Space Syntax techniques. Through the structural morphology of dwellings can be inferred quality networks, levels of connectivity and depth and places of openness or closure within the dwelling under study, or under design. How, then, have intelligently contributed this digital craft to the perception of those spatial fixtures ? The aim of this research is to apply an appropriate program in the field of vernacular residential design and notably Space syntax which relate to the understanding and analysis of spatial structures, and also demonstrate its role at the morphological and spatial structure aspects, and prove how effective it helps to understand the social logic of domestic space through social individual/collective relationships and behaviors projected on the spatial configurations of dwellings. The answer to the issue raised above and at the methodological aspect, the study discussed the application of space syntax techniques on the subject. The findings tend to prove the efficiency by comparing samples of Berber vernacular domestic spaces from the Mzab, the Aures and Kabilya in Algeria, and has also led to ascertain the intelligibility of space syntax techniques in reading the differences between the behaviors in domestic spaces in different areas of the sample through long periods of time .

title Flexible Formwork: A methodology for casting funicular structures
source Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 345-352
summary This paper describes a method for design and fabrication of funicular structures from discrete precast concrete components. It has a critical look over traditional casting techniques and proposes a new methodology to fabricate a flexible formwork. The design process is engaged with a thorough series of analytical models and employs digital computation techniques to test their structural efficiency. Scripting, modeling and prototyping have been integrated to investigate several case studies through which a set of criteria was developed. Digital modeling tries to keep a limited number of varied components that have certain conditions at joints and flexible in other parts. This variation helps to meet the structural criterion and the flexibility of formwork results the efficiency of fabrication.

title Crafting the Virtual Sensory Environment: building performance simulation visualization as an enabler for creating sensory environments
source Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 353-359
summary The sensory virtual environment is defined as a cognitive method leading to a mental model of potential value in gaining insights of how building spaces may perform to enhance the sensory experience of occupants. For architects, creating a sensory and experiential space is the holy grail of design endeavours. So far, the results of the experiential and sensory success of buildings are dependent on the architects’ own experience and judgment of materials and compositions within the space. Currently the use of tools such as 3D Max provides an ocular experience of the crafted virtual space, rarely giving indications of daylight and possible sensory experiences of the indoor thermal and acoustic conditions. In practice testing the thermal, daylight and other environmental performances of buildings at design stage is within the remit of building services consultants for conformity regulatory checks, and is dominated by extensive 2D (graphs) information exchanges. There is a need to include other formats of visual information exchanges to facilitate decisions on sustainable buildings and to achieve performing sensory environments This paper presents an exploration of endeavours to test the virtual sensory space through visualizations of building performance and aims to provide recommendations on how to fuse endeavours to disseminate knowledge within the design team while creating an information exchange mechanism that captures experts’ explicit and tacit knowledge. Case studies will be presented on how building performance simulation tools are used to provide matrices of relations to indicate the building performance, thermal comfort, daylight and natural ventilation and were used as an aid for architectural design decisions to create sensory environments.

summary The "PURE Tension" Pavilion is a lightweight, rapidly deployable, tensioned membrane structure and portable charging station commissioned by Volvo Car Italia to showcase the new Volvo V60 Hybrid Electric Diesel car. Officially launched in Milan, Italy in October 2013, this experimental structure was developed through a process of rigorous research and development that investigated methods of associative modelling, dynamic mesh relaxation, geometric rationalization, solar incidence analysis, membrane panelling, and material performance. It is an experimental structure that, similar to a concept car, is a working prototype that speculates on the potential future of personal mobility and alternative energy sources for transportation while also exploring digital design methodologies and innovative structural solutions. This paper will illustrate the design, development and fabrication processes involved in realizing this structure.

title Mobile Application to Collect Information About Architecture to Obtain a Collective Knowledge Base: 'ar:searchbox.app'
source Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 375-382
summary During the early stages of the architectural design process, students and architects seek information for inspiration, and to evaluate design ideas or similar solutions. An essential part of design education therefore involves building up a knowledge base of already built or designed buildings. Most students gather such information by visiting or researching building designs, for example through photos taken on design studio field trips. These photos are used for studio work or archived for later use. The “ar:searchbox.app” aims to support this in two ways. Firstly, by supporting easy mobile information acquisition and sharing, as well as the semi-automatic derivation of high quality metadata; and secondly, by employing urban environment sensitive search and similarity-based browsing strategies to support mobile education as well as a web-based access to the information. To provide long-term access and to establish an information base that is not restricted to a single design studio, the “ar:searchbox.app” builds on our previous “ar:searchbox” project which uses a central media server called “mediaTUM” that provides a handling concept for flexible metadata schemas and scalable infrastructures.

summary Human imagination has played with the idea of an alternative technological world for years. From dystopian proposals like Neuromancer or The Matrix to more positive views like the recent Upload series, the exploration of the friction between the digital world and the physical world has entertained the imagination of our society for decades. Outside the fictional environments, the omnipresence of the internet and the development of “the cloud” are showing that the virtual world is possible and that the idea of a Metaverse is no longer part of science fiction but a very real future for human relations (Winters 2021). In line with the idea of the Metaverse, the intersection of the virtual and the physical world is being explored through the idea of Extended Realities. Technology is allowing humans to enhance their capabilities more than ever, and in fact, it has been proposed that we are entering the Augmented era (King 2014). This paper explores the opportunities and possible challenges that “Extended Architecture” has by analyzing a research project based on augmented reality as the media to explore these ideas. This project will propose a speculative approach to how the fact that in the recent future, everyone will have access to an AR device will change the way we perceive and understand our architectural environment.

title Techno Relics: A Framework for Computation, Materiality, and Fabrication in the Anthropocene
source ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 2: Proceedings of the 43rd Annual Conference for the Association for Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9891764-0-3]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 294-303.
summary This paper explores the potential of material, computation, and fabrication methodologies broadly engaging a critical understanding of the human epoch, also known as the anthro- pocene era, and its impact on Earth’s geology. Man-made materials have arguably become ubiquitous and a massively distributed part of the environment, while also placing an involuntary burden on local ecologies. Nature has taken its course and swallowed these synthetic materials to create new compositions of complex conglomerations, thereby blur- ring the boundaries between the agency of man, nature, and technology (Corcoran et al. 2014). The discipline of architecture, too, must reconsider its own boundaries, and evolve to design and fabricate with these techno relics, defined here as a remnant of the techno- logical impact on our planet. In order to understand how these techno relics can be used by designers, this paper pres- ents a general framework for the research, discovery, and validation of computational and fabrication processes. This is done through the examination of the background research in using aluminum waste by leveraging pre-existing digital and physical processes. Furthermore, the paper situates the background work within the broader context of how these techno relics can be mined, or collected. This is done through the examination of a case study that follows plastic waste in the Pacific Northwest through an Indigenous lens, providing possible architectural solutions that are relevant to the building typology in the remote communities most affected.
