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.

title	Impacts on the landscape coast of Joao Pessoa-PB: an analysis based on digital simulations
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 1809–1820
summary	The research analyzes the impact of artificial beach nourishment in Joao Pessoa - PB, considering the increase in buildings and its environmental and social consequences. Urban beaches are particularly vulnerable to the growing effects of climate change. Artificial beach nourishment is proposed as a response to coastal erosion, but experts raise concerns about its high cost, ecosystem imbalance, destruction of fragile biomes, and impact on local communities. The research employs digital simulation (Scheer, 2014) through generative visual models as resources to analyze the beach nourishment project in Cabo Branco and Tambaú. Various visualization techniques and means are overlapped to simulate images linked to the real impacts of the proposed interventions. The study also explores the relationships between gray, green, and blue infrastructures and the effects on shading and ventilation caused by the buildings. The purpose is to understand the social, environmental, and urban dynamics' impacts on the city.

summary	The study of wind conditions in the urban context has multiple application areas such as for cleaning pollution through ventilation, analysing wind pressures on building façades, and improving pedestrian comfort. In this context, the Pneumosense project is a student’s project focused in the design of a kinetic system to ameliorate negative impact of wind conditions in pedestrian areas in the city of Melbourne. Its development considers several stages including site analysis, analogue wind tunnel testing, digital simulations with Computational Fluid Dynamic software, material explorations, kinetic component design with Arduino, and rapid prototyping.

title	A CFD Analysis of the Urban Morphology Effect on Air Pollutants Dispersion
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. 395-403
summary	Air pollution in urban environments can have negative consequences on people's health and comfort of city-dwellers, and on the durability of buildings. Understanding the transfer and deposition of pollutants in the urban environment is therefore essential in the design process of a building. Computational simulations can aid in understanding the pollutant/chemical dispersion in the urban cityscapes. Computational fluid dynamics (CFD) represents the study of fluid mechanics with the use of computer models and simulations. In this paper we study the impact of urban planning on pollution dispersion, the dispersion characteristics, such as the spread of the pollution dispersions, have been determined for different wind speeds and wind directions.

title	Experimental Material Research - Digital Chocolate
doi	https://doi.org/10.52842/conf.acadia.2016.424
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. 424-431
summary	This research investigates the aesthetics of a shared agency between humans, computation and physical material. ‘Chocolate’ is manipulated in physical and virtual space simultaneously to extract aesthetic conditions that are a sum of human and non-human relations. This is an attempt to further the knowledge of designing, giving physical and digital materials force in determining their own aesthetics. The research springs from work in speculative aesthetics, particularly N. Katherine Hayles’s OOI (object-oriented inquiry) and Graham Harman’s OOO (object-oriented ontology) and explores how these ideas impact contemporary computational architectural design. To study this, a simple material has been chosen, chocolate, and used as a vehicle to investigate the dynamics of physical and digital materials and their shared/differing ‘resistances to human manipulation’ (Pickering 1995). Digital chocolate is ‘melted’ through virtual heat, and the results printed and cast in real chocolate, to be further manipulated in real space. The resistances and feedback of physical and digital chocolate to human ‘prodding’ (Hayles 2014) are analyzed in terms of a material’s qualities and tendencies in digital space versus those in physical space. Observations from this process are used to speculate on an aesthetics where humans, computation and physical material are mutually agential. This research is a pilot for a larger study taking on more complex conditions, such as building and cities, with a view to broadening how aesthetics is understood in architectural design. The contribution of this research to the field of architectural computation is thus in areas of aesthetic speculation and human/non-human architectural authorship.

title	Building Energy Efficiency Estimations with Random Forest for Single and Multi-Zones

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.

title	Building-up urban open spaces from shadow range analyses
doi	https://doi.org/10.52842/conf.ecaade.2014.1.129
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 129-135
summary	This paper explores an alternative approach for the creation of new built forms based on solar access analysis. Consolidated on urban areas under development, the denominated 'inverted' approach is focused on the generation of recreational open spaces based on shadow conditions caused by existing built forms, and as a starting point for the construction of new urban envelopes as possible development areas. Unlike the existing method of the 'solar envelope', the 'inverted' approach shows an alternative procedure for the construction of built forms, based on pedestrian comfort caused by solar access in urban spaces rather than on indoor performance affected by the penetration of sunlight into buildings. As a method for the creation of urban envelopes, this approach attempts to enhance pedestrian comfort according to the study of solar access in urban areas. The 'inverted' approach is based on sun path data and is developed as a generative procedure, where the results of shadow range analyses and the different urban objectives work as input parameters for the generation of urban envelopes. Based on this methodology, two Grasshopper® custom components are developed.

summary	The concept of “families” lies in the core of internal data structure in Building Information Modeling (BIM). The elements of this modeling platform are all associated with each other as parts of the “families”, independent of their geometrical structure, materiality, parametric dependencies or their physical connection to other elements. Through the associations introduced among the parameters of the ‘families’ members, this study aims at establishing a methodology for a multi-objective evaluation of the environmental performance of the building as an organism. The methodology is founded on a system of different values and weights attributed to the parameters of the families members which are adjusted and fine-tuned through a series of iterations, thus affecting the overall building performance towards an optimum goal. The performance evaluation method used in the “families” methodology is not limited to the individual assessment of the environmental performance objectives or to an integrated multi-objective weighting mechanism; as an overall evaluation platform it checks and balances the individual characteristics of the system not as static conclusive results but as dynamic criteria intended to guide the overall design and building process. The importance of this paper lies in the construction of a concrete methodological set of tools for the assessment of the environmental performance of the building. It will lead the way in independent research in the field of architectural design and the development of ecological thinking and building in China.

title	Approaching Sentient Building Performance Simulation Systems
doi	https://doi.org/10.52842/conf.ecaade.2014.2.049
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 2, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 49-60
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.

summary	This paper is about designing a process to create a lightweight building envelope using a shrinkfilm. The advantage of using this material for architecture is that we can simply construct the complex geometry without requiring an expensive formwork. In addition to this, this research illustrates the methodology to control the 3-dimensional form of the shrink-film by using simple 2-dimensional patterns. These patterns enable us to easily manipulate the form. In this paper, the simulation and the prototyping are conducted in both physical and computational methods.

title	Agents' movement_towards the reformation of public space - Step 1: select \| implement \| observe crowd rules
doi	https://doi.org/10.52842/conf.ecaade.2014.1.053
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 53-62
summary	In order to enable designers to envision the behaviour of pedestrians with reference to specific environments, computational models of crowds and their movement become indispensable tools of evaluation as well as tools of creativity. In this paper, the model under development constitutes a generic model which incorporates ideas about agent-based systems. The simulation program comprises a support system for the designer to place virtual users in a context that bears analogous environmental traits of the area under study. The design problem which is addressed by the implementation deals with public squares for which the programmatic demands involve a broad spectrum of users of diverse idiosyncrasies. Our study attempts to elucidate how the variation in preferences of pedestrian movement which depend on various personal, situational and environmental factors, may influence the current use of a selected public space and underpin qualitative alterations compared to its initial design. The intent of the methodology is not to create a predictive tool of naturalistic human movement but to explore how spatial configuration can be assessed and developed through a simulation model of pedestrian behaviour.

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	A Thousand BIM: A rapid value-simulation approach to developing a BIM tool for supporting collaboration during schematic design
source	International Journal of Architectural Computing vol. 12 - no. 1, 47-60
summary	The purpose of this study is to develop a BIM-based plug-in that is able to assist a collaboration among heterogeneous professionals. The tool will enable them to communicate in the same language, articulate criteria and priorities in multiple perspectives, and to share rapidly simulated evaluations of schematic design variations. Among many barriers that block collaborations among professionals, a quintessential barrier in the building and design industries may be epistemological rather than physical. The professionally different ways of thinking, expertise, values, and priorities can be a block on the collaborative development process of architectural design projects. This paper takes the example of the relationship between developers and architects, who tend to have different evaluation criteria. A real-time value simulation tool is introduced as a means to generate possible building typologies on a given project site, with computation of expected total values expressed in simple financial terms.

title	Binocular Disparity and Depth Cue of Luminance Contrast
doi	https://doi.org/10.52842/conf.caadria.2014.637
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. 637–646
summary	Luminance contrast has been identified as an effective depth cue through perceptual studies using digital images generated by the integrated technologies of physically based lighting simulation and perceptually based tone mapping. However, the prior established framework utilizes a single camera viewpoint, failing to address the binocular vision of the human visual system. In this study, the computational framework is extended to incorporate 3-dimensional (3D) stereo display technology. Psychophysical experiments were conducted to investigate the depth effect of luminance contrast on the experimental scenes presented on conventional and stereo displays. The objective of this study was twofold: first, to investigate the effect of luminance contrast on depth perception, considering binocular vision; second, to further advance the visual realism of the computer-generated environment to reflect the perceptual reality of static pictorial and binocular disparity cues.

summary	Education and Research in Computer Aided Architectural Design in Europe faces many urgent tasks. Among the Architecture, Engineering and Construction (AEC)international scientific societies, only few researches systematically investigate on how to integrate the design solutions with Health and Safety (HS) planning measures, enhancing a collaborative “fusion” of all involved actors in Design and Construction decision making. Process automation cannot be enhanced until design/management tools, such as Building Information Models, can rely only on entities formalised "per se" geometrical items fulfilled by isolated-object specific information. To face complex problems, BIM models should be able to implement and manipulate multiple sets of entities, qualified by clearly established relationships, belonging to organically structured and oriented (sub-) systems. This paper reports on an early stage research project, focused on the identification of operative rules for Health and Safety design. Implementation on the unique case study of Palazzo della Civiltà Italiana functional refurbishment faces two main objectives: one, more pragmatic, is concerned with boostingworkers education about non-standard operative tasks, by means of accurate ad-hoc construction narrative visualisation; another one, more challenging and theoretically complex, consists in modelling "judgment-based" rules, aimed at supporting automated reasoning in Safety Design.

title	A Synchronous Distributed Design Study Meeting Process with Annotation Function
doi	https://doi.org/10.52842/conf.caadria.2014.749
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. 749–758
summary	This research investigated the impact of synchronous distributed non immersive cloud-VR (cloud computing type of Virtual Reality) meetings using the annotation function by noting an architectural design process. The experimentation of collaborative design work at the early stage of a housing renovation project was executed by three designers. The synchronously distributed meetings using cloud-VR and a freehand sketching function were completed in two days. The annotation function was used effectively when a designer wished to show the space composition and volume shape of the planned building and so on. The proposed design environment, sharing a 3D virtual space with viewpoints, plans, sketches and other information synchronously and remotely, was feasible and effective.

title	Techno Relics: A Framework for Computation, Materiality, and Fabrication in the Anthropocene

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.

summary	This paper focuses on the objective study of emotions, namely, fear induced by architectural spaces, by sensing and statistically analysing some physiological signals of users experiencing Virtual Environments (VE). For this, a virtual building was designed considering the presence of stairs and ramps as architectural elements that could affect users´ physiological states and perception of fear of falling. Thirty-one older persons participated in this study and were assigned to two experimental conditions (i.e., safe and unsafe conditions). Five main locations (beginning of the stairs; neutral room; first descending ramp; ascending ramp; and the middle of ascending ramp) were considered along the participants' path, and heart rate (HR) was collected in the vicinity of those locations. Results shown significant differences in HR activation among neutral, beginning of stairs and middle of ascending ramp. Despite the fact that the effect of condition was not fully verified for HR, participants reported more fear while interacting with the unsafe condition, with significant differences between conditions.
