summary	Building energy performance assessments are complex multi-criteria problems. Appropriate tools that can help designers explore design alternatives and assess the energy performance for choosing the most appropriate alternative are in high demand. In this paper, we present a newly developed integrated parametric Building Information Modeling (BIM)-based system to interact with cloud-based whole building energy performance simulation and daylighting tools to optimize building energy performance using a Multi-Objective Optimization (MOO) algorithm. This system enables designers to explore design alternatives using a visual programming interface, while assessing the energy performance of the design models to search for the most appropriate design. A case study of minimizing the energy use while maximizing the appropriate daylighting level of a residential building is provided to showcase the utility of the system and its workflow.

title	The BIM based Responsive Environmental Performance Design Methodology

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.

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	Material Swarm Articulations, is an experiment in developing a multi-objective optimization system that incorporates bottom up approaches for informing architectural design. The paper presents an initial built project that demonstrates the combination of a structural form finding method, with an agent based design system through the digital fabrication processes. The objective of this research is to develop a workflow combined with material and construction constraints that has the potential to increase performance objectives while enabling geometric complexity and design driven articulation of a traditional tectonic system. The emphasis of the research at this stage is to take advantage of material properties and assembly methods applied to a digital design and simulation workflow that enables emergent patterns to influence the performance of the space.The paper illustrates the research through a prototype of a self standing canopy structure in 1:1 scale. It presents results of the form finding, generative patterning, digital fabrication affordances and sets and agenda for next steps in the use of multi-agent systems for design purposes.

title	Adaptive [skins]: Adaptation through smart systems
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. 275-289
summary	The project investigates responsive building skin systems that adapt to the dynamic environmental conditions to regulate internal conditions in a habitable space over different periods of time by exhibiting a state of motion and dynamism. Passive and active building skins are developed using shape memory alloys and pneumatic actuators through investigations of smart systems that integrate smart materials and smart geometries. Nitinol springs are integrated in tensegrity systems to actuate the adaptive behaviour, which forms the passive roof system. Owing to the complexity of the multi-parametric system, genetic algorithms are developed for system optimization and calibrated with physical prototypes at varied scales. The developed systems are tested against two distinct climatic models- New Delhi and Barcelona, and evaluated for performance, based on heat and light, which are quantified as solar gain and illuminance as principles, and daylight factor for evaluation purpose. New tool-sets are developed in the process by combining various digital tools, to create a real-time feedback and memory loop system.

title	Towards a BIM-Based Energy Rating System

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 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	Immersive Virtual Environments: Experiments on Impacting Design and Human Building Interaction
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. 729–738

summary	This research prefaces the need for engaging with endusers in early stages of design as means to achieve higher performing designs with an increased certainty for enduser satisfaction. While the architecture, engineering, and construction (AEC) community has previously used virtual reality, the primary use has been for coordination and visualization of Building Information Models (BIM). This work builds upon the value of use of virtual environments in AEC processes but asks the research question "how can we better test and measure design alternatives through the integration of immersive virtual reality into our digital and physical mock up workflows? " The work is predicated on the need for design exploration through associative parametric design models, as well as, testing and measuring design alternatives with human subjects. The paper focuses on immersive virtual environments (IVEs) and presents a literature review of the use of virtual environments for integrating enduser feedback during the design stage. In a controlled pilot experiment, the authors find that human participants perform similarly in IVE and the physical environment in everyday tasks. The participants indicated they felt a strong sense of "presence" in IVE. In the future, the authors plan on using IVE to explore the integration of multi agent systems to impact building design performance and occupant satisfaction.

title	Closing the Loop: From Analysis to Transformation within BIM
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 347-357.
summary	The shift from traditional CAD to BIM has created a significant potential to embed optimization processes in many stages of the design. The presented research is situated in the early design stage of inception and concept, focusing on analysis-driven-form-finding during the integrated design approach within a BIM environment. A custom analysis framework, has been developed and linked to a visual programming environment that allows the exchange of data with the parametric components of a BIM environment. The developed workflow and sequential split of functionalities enables a shared design environment for multiple experts and the design-team. The environment is intended to close the loop from analysis to parametric modeling in order to generate and evaluate building designs against performance criteria, with the aim to expedite the design decision process. The prototype has been presented to participants of the Deep-Space Cluster at SmartGeometry 2014.

summary	Current parametric design software lacks the capacity to integrate simulation and optimisation when they would be most relevant: at the early stages of the design process. This paper presents a novel framework to address this issue: A parametric program that supports performance-based modelling by integrating detailed physical simulation modules that also take construction issues into account, while at the same time providing easy access to high-level optimisation approaches. Providing bidirectional parametric modelling capabilities, we refer to the system under development as augmented parametrics. It is being developed as part of a research project sponsored by the Austrian Science Foundation.

title	Performance Based Exploration Of Generative Design Solutions Using Formex Algebra
source	International Journal of Architectural Computing vol. 12 - no. 3, 321-338
summary	This paper illustrates the use of a computational form-finding method called ParaGen which aids the designer in the exploration of arrays of good solutions. Although the method is guided by a multi-objective optimization program, the goal is to promote the exploration of the solution space based on designer selected combinations of performance objectives. The digital form generation of the bridges is carried out using Formian, a program which uses Formex algebra to describe a wide array of geometric configurations. This form generation is linked to structural simulation and design software (STAAD. Pro) to determine performance values. Finally, ParaGen is used to build a database of all solutions and guide the exploration based on performance values. Using this database, both visual and numeric characteristics are explored.

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	Bricks have been used in the construction industry as a building medium for millennia. Distinct patterns of bricks depict the unique aesthetic intentions found in Roman, Gothic and Islamic architecture. In contemporary practice, the use of digital tools in design has enabled methodologies for creating new forms in architecture. CAD and BIM systems provide new opportunities for designers to create parametric objects for building form generation. In masonry design, there exists an inherent contradiction between traditional patterns in brick design, which are formal and prescribed, and the potential for new patterns generated using design scripting. In addition, current tools do not provide interactive techniques for the design of brickwork patterns that can manage constant changes parametrically, to inform and influence design process, by providing design feedback on the constructive and structural aspects of the proposed brick pattern and geometry. This research looks into the parametric techniques that can be applied to create different kinds of patterns on brick walls. It discusses a methodology for an interactive brickwork design within generative techniques. By integrating data between two computational platforms – the first based on image analysis and the second on parametric modeling, we demonstrate a methodology and application that can generate interactive arbitrary patterns and map it to the brick wall in real-time.

summary	Real estate development may benefit from a decision-support software system that is implemented with Building Information Modelling to perform Quadruple Net Value Analysis. Schemes may be created rapidly using BIM and parametric modeling. They may be assessed for economic, social, and environmental factors using spreadsheets and simulation software. They may be assessed for sensory value by using an immersive visualization system. The idea has been tested as a proof of concept in undergraduate and graduate design studios. It appears to be easy to use for students and effective in directing attention to the four factors and obtaining objective measurements.

title	A BIM-based Framework for Assessing Architectural Competition Entries

summary	Architectural competitions have been traditionally used to select best design practices. The basis of assessment for competitions has typically involved non-technical concepts of quality, subjective and emotional appreciations of experiences, and inseparable accord of formal, functional, aesthetic and contextual values (Rönn, 2011), rather than clear-cut objective and precisely measured values as in the engineering domain (Nashed, 2005; Nelson, 2006). Criteria for judgment usually focus on design parti and clarity of concept, novelty of architectural approach, context compliance, spatial organization, functional adaptability, economical solutions, and design flexibility. The assessment process, although presumably comprehensive and involving multiple evaluation techniques and resources, may still overlook important technical issues that may be fundamentally significant to the exclusion or approval of a given entry. This paper introduces a framework for assessing architectural competition entries aided by concepts of building information modeling (BIM).

summary	A multi layered breathing envelope is developed as a method of natural ventilation. The two main layers consist of mineral wool and air permeable concrete. The mineral wool works as a dynamic insulation and the permeable concrete as a heat recovery system with a high thermal mass for heat storage. The performance of the envelope is simulated and put through an optimization process. The impact of a design system on the architectural potential of Performance -based design was investigated.

summary	This article proposes to study the process of parametric design integrated analysis and structural design. This application model is called Performative Model; the form is generated based on performance criteria. The digital tools facilitate the information flow between designers using parametric model and Finite Element Analysis. To research the method of Performative Model is proposed the development of a conceptual framework of lattice wind tower with the aim of a quantitative and qualitative structure optimization. Therefore, the parametric modeling will be done using Rhinoceros software, the plugin for creating algorithms Grasshoper and structural analysis plugin Scan & Solve.

summary	For most architects, it is not easy to transform their free form of designs into constructable building without precise knowledge structural design and more often the architect need ask structural engineer for consultation. Yet the structural performance of building itself provides possibility for the architect to explore a new form-finding procedure and An approach is introduced in this article and it could be adopted by architects concerning the works of predicting the structural performance in the early design stage. The approach has been developed throughout the architecture history and recently it turns into a computational methodology for architectural design. This article analysis the structural performance design history in architect’s view, compares and explain the current Structural performance-based design methodology and evaluate its value for architecture design.
