summary	The last decade have seen substantial calls and increasing pressure for developing an integrated design teaching framework, where sustainability is an imperative priority. This paper focuses on presenting a taxonomy of the main challenges encountered within the educational domain, in the attempt to reach an effective integration. The paper also presents a set guidelines to address and try to resolve the noted challenges. As the use of Building Performance Simulation (BPS) applications is a central approach in this process aiming to reach energy efficient buildings, the paper focuses on the shortcomings noted as a result of the use of these applications in the design studios, with particular emphasis on the thermal and lighting aspects of the simulation. The taxonomy presented is a summary of the findings from literature review, as well as the surveys results which were part of the author's research project discussed in the paper.

title	Building Energy Efficiency Estimations with Random Forest for Single and Multi-Zones
source	Kontovourkis, O, Phocas, MC and Wurzer, G (eds.), Data-Driven Intelligence - Proceedings of the 42nd Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2024), Nicosia, 11-13 September 2024, Volume 2, pp. 365–374

summary	Surrogate models (SM) present an opportunity for rapid assessment of a building's performance, surpassing the pace of simulation-based methods. Setting up a simulation for a single concept involves defining numerous parameters, disrupting the architect's creative flow due to extended simulation run times. Therefore, this research explores integrating building energy analysis with advanced machine learning techniques to predict heating and cooling loads (KWh/m2) for single and multi-zones in buildings. To generate the dataset, the study adopts a parametric generative workflow, building upon Chou and Bui's (2014) methodology. This dataset encompasses multiple building forms, each with unique topological connections and attributes, ensuring a thorough analysis across varied building scenarios. These scenarios undergo thermal simulation to generate data for machine learning analysis. The study primarily utilizes Random Forest (RF) as a new technique to estimate the heating and cooling loads in buildings, a critical factor in building energy efficiency. Following that, A random search approach is utilized to optimize the hyperparameters, enhancing the robustness and accuracy of the machine learning models employed later in the research. The RF algorithms demonstrate high performance in predicting heating and cooling loads (KWh/m2), contributing to enhanced building energy efficiency. The study underscores the potential of machine learning in optimizing building designs for energy efficiency.

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). That may have seemed a straightforward proposition forty years ago, when the association was founded. A look at the breadth and depth of research topics presented and discussed at this conference (and as a consequence in this book, for which you’re reading the editorial) shows how the field has developed over these forty years. There are sessions on Digital Design Education, on Digital Fabrication, on Virtual Reality, on Virtual Heritage, on Generative Design and Machine Learning, on Digital Cities, on Simulation and Digital Twins, on BIM, on Sustainability, on Circular Design, on Design Theory and on Digital Design Experimentations. We hope you will find what you’re looking for in this book and at the conference – and maybe even more than that: surprising turns and happy encounters between Design and the Digital.

summary	Reverse engineering is been applied in industry for many years, particularly in the context of the software industry, with the subsequent theoretical development, especially from the 1990s. In this paper we propose to realize their potential application to the field of design, and then characterize the concept of Reverse Design, associated with the idea of projectual deconstruction, concept that has great potential, from didactics to the optimization of materials and energy. Based on a literature review of the state, we will use the basic texts of reverse engineering to establish parallels, differences and contributions to the discipline.

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.

summary	Rethinking Comprehensive Design—the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014)—emphasises a cross-disciplinary context to challenge the mainstream culture of computational design in architecture. It aims to (re)explore the potential of computational design methods and technologies in architecture from a holistic perspective. The conference provides an international forum where academics and practitioners share their novel research development and reflection for defining the future of computation in architectural design. Hosted by the Department of Design, Engineering and Management at the Kyoto Institute of Technology, CAADRIA 2014 presents 88 peer-reviewed full papers from all over the world. These high-quality research papers are complimented by 34 short work-in-progress papers submitted for the poster session of the conference. The conference proceedings were produced by a motivated team of volunteers from the CAADRIA community through an extensive collaboration. The 88 full papers rigorously double-blind reviewed by the dedicated International Review Committee (consisting of 74 experts), testify to CAADRIA’s highly respectable international standing. Call for abstracts sent out in July 2013 attracted 298 submissions. They were initially reviewed by the Paper Selection Committee who accepted 198 abstracts for further development. Of these, 118 full papers were eventually submitted in the final stage. Each submitted paper was then assessed by at least two members of the International Review Committee. Following the reviewers’ recommendations, 91 papers were accepted by the conference, of which 88 are included in this volume and for presentation in CAADRIA 2014. Collectively, these 88 papers define Rethinking Comprehensive Design in terms of the following research streams: Shape Studies; User Participation in Design; Human-Computer Interaction; Digital Fabrication and Construction; Computational Design Analysis; New Digital Design Concepts and Strategies; Practice-Based and Interdisciplinary Computational Design Research; Collaborative and Collective Design; Generative, Parametric and Evolutionary Design; Design Cognition and Creativity; Virtual / Augmented Reality and Interactive Environments; Computational Design Research and Education; and Theory, Philosophy and Methodology of Computational Design Research. In the following pages, you will find a wide range of scholarly papers organised under these streams that truly capture the quintessence of the research concepts. This volume will certainly inspire you and facilitate your journey in Rethinking Comprehensive Design.

title	Education to practice to ecology: A review and preliminary evaluation of a new architectural design curriculum using computational design tools and bamboo in Haiti
source	SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 643-651
summary	There is an absence of lightweight, sustainable construction materials in contemporary Haitian construction, a fact highlighted in the disproportionate loss of life in the 2010 Port-au-Prince earthquake. Between 2014 and 2017 the authors delivered a series of architectural design workshops in Haiti to raise awareness and develop design skills for bamboo using computational design tools. This paper provides a review of these workshops and a preliminary evaluation from surveys conducted with the course participants. Results showed architectural education had changed perceptions of bamboo and showed potential positive ecological impact due to subsequent reforestation activities instigated by participants. Weaknesses were in the lack of subsequent use of parametric modelling software. Bamboo material knowledge and a new architectural design methodology have been most relevant to their professional or academic work.

summary	This work aims to review the literature on digital fabrication verifying the Brazilian status on a general view. Concerning the methodology, the research was carried out from 2004 to 2014 analyzing three aspects: 1. the situational context of digital fabrication; 2. digital fabrication in the design process; 3. the Brazilian status. The findings revealed the use of digital fabrication is mainly focused on the design process. Also, the most common objects in the research are the development of models, furniture and pavilions. Moreover, digital fabrication is increasingly being inserted in the syllabus of architecture schools. Brazil strikes in object production both in quantities and interests throughout the country.

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	The influence of urban morphology on the energy consumption of a fabric has been recently established by research into the energy use of existing cities. This paper suggests a framework for generating environmentally adapted urban tissue by using genetic algorithms as form-finding processes. A series of multi-objective optimization algorithms are described. The geometric abstractions used as a basis for these algorithms are illustrated in detail, and the results and implications of these types of simulations are discussed. The methodology developed within this paper was tested on one km2 site in three cities of varying climates, and further expanded into a detailed case study within one city.

summary	Contemporary architecture replaces the concept facade by skin: outer layer mediating between the building and its surroundings; active, informed, connected and communicative membrane. Our training and practice in architecture, still working for the rigor and stability of modular geomerías on determinants of a unique spatial and morphological situation passive. In the teaching of architecture in Latin America there are no exercises that incorporate a learning design to create flexible dynamic geometries as possible structures for sensitive skin. The research aims to explore the possibilities and systematize the dynamic folding of planar surfaces using geometric simulation programs (freeform origami, Grasshopper); building scale prototypes (rapid prototyping and arduino microcontroller) and subsequent verification of energy analysis program.

title	Teaching and Learning Building Performance Virtualisation
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. 323-330
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.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing

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	The city of Vienna follows a long-term initiative to become a Smart City. Within 2050 it aims to reduce 80% of the CO2 emissions (in comparison to 1990) and looks forward to generate ways for a sustainable energy production. (Smart City Framework Strategy 2014) Reaching this targets requires a complex planning process which involves interdisciplinary stakeholders and decision makers. An interactive multi-dimensional environment, comprising spatial objects and data models, is a helpful tool during these planning processes. This paper proposes a suitable path for the development of a structural framework for such an environment. The benefits of such an environment are shown in detail, based on an application of the economic solar heat potential in Vienna.

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	An Adaptive Decision-Making Framework for Designing Material Behaviours
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. 55–64

summary	This paper describes an adaptive decision-making design framework for investigating the synergies between aesthetically-driven and performance-driven criteria, specifically in designing the material behaviour of an electroresponsive building envelope system. An immersive and interactive simulation environment developed in the C++ programming language provides a computational tool for testing the visual and energetic performance of a dynamic building envelope as it negotiates bioclimatic energy flows with participants’ aesthetic preferences and interactions. Experiments in bioresponsive feedback loops examine the impacts that user engagement and real-time energy performance feedback have on participants’ design choices. Preliminary results demonstrate that exposure to energy performance feedback and to the collective design choices of multiple users leads to adaptive decision-making that favours synergistic system performance with the potential for increased socio-ecological connections. Critically, this research provides new methods for supporting the design of emerging material behaviours for dynamic building envelopes that can negotiate multiple performance criteria.

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.
