title	Optimo: A BIM-based Multi-Objective Optimization Tool Utilizing Visual Programming for High Performance Building Design
doi	https://doi.org/10.52842/conf.ecaade.2015.1.673
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 673-682
summary	Within the architecture, engineering, and construction (AEC) industry, the application of multidisciplinary optimization methods has been shown to reach significant improvements in building performance compared to conventional design methods. As a result, the use of multidisciplinary optimization in the process of design is growing and becoming a common method that provides desired performance feedback for decision making. However, there is a lack of BIM-based multidisciplinary optimization tools that use the rich information stored in Building Information Models (BIM) to help designers explore design alternatives across multiple competing design criteria. In this paper we introduce Optimo, an open-source visual programming-based Multi-Objective Optimization (MOO) tool, which is developed to parametrically interact with Autodesk Revit for BIM-based optimization. The paper details the development process of Optimo and also provides the initial validation of its results using optimization test functions. Finally, strengths, limitations, current adoption by academia and industry, and future improvements of Optimo for building performance optimization are discussed.

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.

title	Generative Design Methods - Implementing Computational Techniques in Undergraduate Architectural Education
doi	https://doi.org/10.52842/conf.ecaade.2015.2.047

summary	In continuation to the Deceptive Landscape Installation research project (Agkathidis, Kocatürk 2014), this paper investigates the implementation of generative design techniques in undergraduate architectural design education. After reviewing the main definitions of generative design synoptically, we have assessed the application of a modified generative method on a final year, undergraduate design studio, in order to evaluate its potential and its suitability within the framework of a research led design studio, leading to an RIBA accredited Part I degree. Our research findings based on analysis of the design outputs, student performance, external examiners reports as well as student course evaluation surveys indicate a positive outcome on the studio's design approach, as well as its suitability for an undergraduate design studio. They initiate a flourishing debate about accomplishments and failures of a design methodology, which still remains alien to many undergraduate curricula.

title	Heuristic Optimization in Design
doi	https://doi.org/10.52842/conf.acadia.2015.357
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 357-369
summary	This paper presents a workflow called the ‘heuristic optimization workflow’ that integrates Octopus, a Multi-Objective Optimization (MOO) engine with Grasshopper3D, a parametric modeling tool, and multiple simulation software. It describes a process that enables the designer to integrate disparate domains via Octopus and complete a feedback loop with the developed interactive, real-time visualization tools. A retrospective design of the Bow Tower in Calgary is used as a test case to study the impact of the developed workflow and tools, as well as the impact of MOO on the performance of the solutions. The overall workflow makes MOO based results more accessible to designers and encourages a more interactive ‘heuristic’ exploration of various geometric and topological trajectories. The workflow also reduces design decision uncertainty and design cycle latency through the incorporation of a feedback loop between geometric models and their associated quantitative data. It is through the juxtaposition of extreme performing solutions that serendipity is created and the potential for better multiple performing solutions is increased.es responsive systems, which focus on the implementation of multi-objective adaptive design prototypes from sensored environments. The intention of the work is to investigate multi-objective criteria both as a material system and as a processing system by creating prototypes with structural integrity, where the thermal energy flow through the prototype, to be understood as a membrane, can be controlled and the visual transparency altered. The work shows performance based feedback systems and physical prototype models driven by information streaming, screening, and application.

title	The definition of semantic of spaces in virtual built environments oriented to BIM implementation
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. 331-346.
summary	The BIM today can be a provider of inputs to performance analysis of different phenomena such as thermal comfort, energy consumption or winds. All these assessments are fundamental to the post occupation of the building. The attainment of approximate information of how the future building would behave under these conditions will reduce the waste of materials and energy resources. The same idea is used for evaluating the users occupation. Through simulation of human behavior is possible to evaluate which design elements can be improved. In complex structures such as hospital buildings or airports is quite complex for architects to determine optimal design solutions based on the tools available nowadays. These due to the fact users are not contemplated in the model. Part of the data used for the simulation can be derived from the BIM model. The three-dimensional model provides parametric information, however are not semantically enriched. They provide parameters to elements but not the connection between them, not the relationship. It means that during a simulation Virtual Users can recognize the elements represented in BIM models, but not what they mean, due to the lack of semantics. At the same time the built environment may assume different functions depending on the physical configuration or activities that are performed on it. The status of the space may reveal differences and these changes occur constantly and are dynamic. In an initial state, a room can be noisy and a moment later, quiet. This can determine what type of activities the space can support according to each change in status. In this study we demonstrate how the spaces can express different semantic information according to the activity performed on it. The aim of this paper is to simulate the activities carried out in the building and how they can generate different semantics to spaces according to the use given to it. Then we analyze the conditions to the implementation of this knowledge in the BIM model.

summary	Early design phase energy modelling is used to provide the design team with feedback about the impact of various building configurations. For better energy-conscious and sustainable building design and operation, the construction of BIM data interoperability for energy performance assessment in the early design phase is important. The purpose of this study is to suggest a development of BIM data interoperability for energy performance assessment based on BIM. To archive this, the authors have investigated advantages of BIM-based energy performance assessment through comparison with traditional energy performance assessment; and suggest requirements for development of Open BIM environment such as BIM data creation and BIM data application. In addition, the authors also suggested on BIM data interoperability system and developed mapping interface.

title	Performance-Based Parametric Design : A Framework for Building Envelope Design
doi	https://doi.org/10.52842/conf.caadria.2015.603
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 603-612
summary	Existing performance-based design exploration methods typically suffer from a lack of real-time feedback and a lack of actionable feedback. This paper proposes a hybrid design exploration method that overcomes these issues by combining parametric modelling, surrogate modelling, and evolutionary algorithms. The proposed method is structured as a mixed-initiative approach, in which parametric modelling is the key to creating a synergistic relationship between the architect and the computational system. Surrogate-based techniques will address the issue of real-time feedback, the evolutionary exploration techniques will address the issue of actionable feedback. As a first stage in developing the PEX method, this paper reports on two experiments conducted to identify an appropriate surrogate modelling technique that is efficient and robust.

title	From Morphogenetic Data to Performative Behaviour
doi	https://doi.org/10.52842/conf.caadria.2015.765

summary	This paper presents part of CORK’EWS, a research work developed within the framework of the Digital Architecture Advanced Program 2012/13 at ISCTE-IUL. The main goal of this investigation was to develop a parametric, customizable and adaptive wall system designed for environmental performance. Moreover, the system is based on standard industrial products: expanded cork blocks produced by Amorim Insulation industries. CAD/CAM resources were the essential tools of the research process, where fundamental and practical knowledge is integrated to understand the microstructure morphological properties of the raw material – cork – and its derivate – natural expanded cork. These properties were upscale and adapted to create a wall with an optimized solar control environmental performance. The result is a digitally fabricated prototype of a new customizable industrial product, adaptable to specific environmental conditions and installation setups being therefore easily commercialized. From microstructural morphology to macroscale construction, the research explores new application possibilities through morphogenesis and opens new possible markets for these customizable products.

title	Analysis of Space Layout Using Attraction Force Model and Quadratic Assignment Problem
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. 247-267.
summary	This paper researches the usefulness of computerized space layout programs in an actual problem of space layout of more than 50 design units of unequal sizes. This was tested with two existing space layout optimization methods, Quadratic Assignment Problem (QAP) and Attraction Force Model (AFM) as well as a satisficing method, intuitive approach. Necessary inputs for the evaluation processes, the evaluation processes and the resulting space layouts were analyzed for each approach by one designer. Their performance in the design process was criticized on subjects like preparation of inputs, situations related with multiple trials, evaluation of the resulting space layouts based on given inputs and what those space layouts represented. Generating alternatives is an advantage of computerized space layout approaches so that conditioning on the resulting space layouts decreases in the process but more research has to be done for their practicality in terms of input preparation, evaluation and transfer of outputs. Possible improvements were suggested to increase their usefulness in the professional field.

title	Cost Performance Based Design - Using Digital Technology for Cost Performance Simulation in the Conceptual Phase of Design
doi	https://doi.org/10.52842/conf.ecaade.2015.1.619
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 619-624
summary	This work studies the Performance-Based Design approach, focusing exclusively on cost performance, asking how to launch the architectural portion thinking of the cost of the building in a way that such performance can directly influence the project design and architectural form and how can shape, type and structure of the building influence the final cost of the work. For this, we chose to analyze the DProfiler software for the development of models in order to produce an architectural form that directly meets the performance cost requirements, following specified formal language, which aligns cost and project intention in the initial phase of the design. The research showed that the use of Macro BIM software platform is promising and that the generative design process can and should arise from an organization of the parts and not from predefining it as a whole, achieving an architectural project that is attainable and more sustainable.

title	Phototropism of Tensile Façade System through Material Agency
doi	https://doi.org/10.52842/conf.caadria.2015.127
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 127-136
summary	This paper researches material agencies, mechanical systems and façade designs that are able to respond to environmental changes through local interactions, inspired by biological systems. These are based on a model of distributed intelligence founded on plants and animal collectives, from which intelligent behavior emerges through simple local associations. Biological collective systems integrate material form and responsiveness and have the potential to inform new architectural and engineering strategies. The design approach of this research is based on a data-driven methodology spanning from design inception to simulation and physical modeling. Data-driven models, common in the fields of natural science, offer a method to generate and test a multiplicity of responsive solutions. The driving concepts are three types of evolutionary adaptation: flexibility, acclimation, and learning. The proposed façade system is a responsive textile shading structure which uses integrated actuators that moderate their local environments through simple interactions with their immediate neighbors. Computational techniques coupled to material logics create an integral design framework leading to heterogeneous environmental and structural conditions, producing local responses to environmental stimuli and ultimately effective performance of the whole system.

title	The Computation Turn in Structural Performance Based Architecture Design
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. 211-225.
summary	It is necessary for an architect to engage closely with structural design, to interpret their design idea thoroughly, and it requires carefully collaboration between architect and engineer. The structural performance based design is not only to obey structure principle but to explore different possibilities of engineer and architectural innovation. Architects could apply this method in the earlier stage of design, and it could provide the efficient solution for structure, create a new spatial experience and further improve the construction quality in the later phase of development. In comparison to structural performance-based design in history, the computational technology has made it possible for architects to implement further the structural knowledge in more dynamic and sophisticated environment. This paper will discuss the history development and current transformation of this method. Three research project will explain the current experimental design process and back the idea of this method.

summary	This paper aims to investigate a new methodology for analysing energy performance of buildings with complex kinetic façades. In this research, the flexible movements of individual kinetic façades in a building is determined by the façades' opening ratios and the sun path. The platform development is conducted through a visual programing environment in BIM, and the process is presented with a case study. Finally, the building's energy performance is compared with a building having static façades using whole building energy analysis tool.

summary	This paper aims to discuss different possibilities and methodologies within the field of urban acoustics and the use of digital tools. As an attempt to integrate quantitative methods, such as sound mapping and noise control, with qualitative approaches, such as the soundscape studies, new strategies based on performance oriented design will be addressed. The notion of sonic effect as an important tool for integrating different perspectives will hence be discussed as a possible instrument for structuring generative design experiments. A theoretical framework and a possible design workflow are further drawn to possibly articulate future studies.

title	Optimizing Design Circularity: Managing Complexity in Design for Circular Economy Through Single and Multi-Objective Optimisation
doi	https://doi.org/10.52842/conf.caadria.2022.1.191
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 191-200
summary	This paper advances the application of computational optimization to design for circular economy (CE) by comparing results of scalarized single-objective optimization (SOO) and multi-objective optimization (MOO) to a furniture design case study. A framework integrating both methods is put forward based on results of the case study. Existing design frameworks for CE emphasize optimization through an iterative process of manual assessment and redesign (Ellen MacArthur Foundation, 2015). Identifying good design solutions for CE, however, is a complex and time-consuming process. Most prominent CE design frameworks list at least nine objectives, several of which may conflict (Reike et al., 2018). Computational optimization responds to these challenges by automating search for best solutions and assisting the designer to identify and manage conflicting objectives. Given the many objectives outlined in circular design frameworks, computational optimisation would appear a priori to be an appropriate method. While results presented in this paper show that scalarized SOO is ultimately more time-efficient for evaluating CE design problems, we suggest that given the presence of conflicting circular design objectives, pareto-set visualization via MOO can initially better support designers to identify preferences.

title	BIM for Masonry: Development of BIM Plugins for the Masonry Unit Database
doi	https://doi.org/10.52842/conf.ecaade.2015.1.567
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 567-576
summary	Masonry Unit Database (MUD) is an integral part of Building Information Modeling for Masonry (BIM-M) initiative. MUD provides a data structure framework for storing the required data for digital representation of masonry units. Specific information about masonry units such as price, geometry and physical properties is needed throughout the lifecycle of a building project, including the design, construction, maintenance, and demolition stages. The development of MUD contributes to enhancement of masonry BIM tools for practitioners to incorporate up-to-date masonry product information into their projects. There are five main stages in the development of MUD: development of process map of masonry building project lifecycle, data requirement identification, physical design of database, design of data import structures, and finally design of data export structures. This paper focuses on the development of the SQL based MUD, and a Revit-Dynamo data export plugin for this database. The developed plugin is especially beneficial as it provides a tool for fast and accurate generation of the parametric and data enhanced masonry units as Revit families on the fly from the stored dimensions and attributes in the database. The generated masonry units with this method would be embedded in masonry wall systems in BIM building project.

summary	Key parameter of a reasoning process supporting real time performance is the use of active heuristics that facilitate the achievement of goals in a timely manner (Dodiawala et al. 1989). A real time approach should incorporate speed, timeliness and adaptation during the execution of tasks. Speed and efficient knowledge processing are addressed for the solution of complex building engineering problems, such as the calibration of Building Energy Models (BEM) to the actual performance data. During retrofit projects, calibrated BEM models aid the design process, and provide a solid base for performative assessments. Despite the demand for building performance evaluations, BEM calibration remains a work-intensive task (Lam et al. 2014). This study proposes a time efficient framework for BEM calibration input data management based on the methodology of a blackboard artificial intelligence knowledge processing system. The resulting model was used for sequential data mining for the energy assessment during the renovation of a commercial building.

title	Stress Line Generation for Structurally Performative Architectural Design
doi	https://doi.org/10.52842/conf.acadia.2015.095
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 95-109
summary	Principal stress lines, which are pairs of orthogonal curves that indicate trajectories of internal forces and therefore idealized paths of material continuity, naturally encode the optimal topology for any structure for a given set of boundary conditions. Although stress line analysis has the potential to offer a direct, and geometrically-provocative approach to optimization that can synthesize both design and structural objectives, its application in design has generally been limited due to the lack of standardization and parameterization of the process for generating and interpreting stress lines. Addressing these barriers that limit the application of the stress line methods, this paper proposes a new implementation framework that will enable designers to take advantage of stress line analysis to inform conceptual structural design. Central to the premise of the research proposal is a new conception of structurally-inspired design exploration that does not impose a singular solution, but instead allows for the exploration of a diverse high-performance design space in order to balance the combination of structural and architectural design objectives.

summary	The rise of digital building models has devalued the broad domain of architectural visualization, a former core topic of the domain. At the same time, digital media has opened up new possibilities for interactive and explorative visual representations. Against this background the workshop advocates to rediscover visualization as a distinct topic in the context of architecture and construction. The workshop introduces a method and a theoretic framework for the creation of visual representations from building information models under involvement of architects and engineers as domain experts, and a prototypical implementation, which serves as a proof of concept and allows for the practical application of the method. The workshop presents the prototype based on selected hands-on examples.

summary	With the rapid development of the digital fabrication technology, structural performance based design shows broad application prospects. Based on the research project "Reverse rafter", this paper aims to explore the possibility of simulating and re-applying Chinese traditional wood tectonics with structure performance based computational technology. Taking "eaves rafter" as research prototype, this project employed topology optimization as research method and “Millipede” as analysis tool. Through the comparison between the analysis results of traditional structure calculation and topology optimization method, this project revealed the underlying structural principles of "eaves rafter", based on which a modern reciprocal structure installation was generated through digital design method. CNC cutting technology was employed to ensure the fabrication accuracy in digital fabrication processes.
