We describe our work on providing support for design decision making in generative design systems producing large quantities of data, motivated by the continuing challenge of making sense of large design and simulation result datasets. Our approach provides methods and tools for multivariate interactive data visualization of the generated designs a...
Article
Full-text available
Generative processes and generative design approaches are topics of continuing interest and debate within the realms of architectural design and related fields. While they are often held up as giving designers the opportunity (the freedom) to explore far greater numbers of options/alternatives than would otherwise be possible, questions also arise...

Chapter
Urban planning and design are increasingly often supported by analytical models of urban space. We present a method of representation for analysis and classification of open urban spaces based on physical measures including three-dimensional data to overcome some observed limitations of two-dimensional methods. Beginning with “convex voids” constru...
Conference Paper

This paper concerns the detailing of panel edge joints within the context of an adaptive subdivision system for composite panelling of complex curved surfaces. A general overview of this context is provided, followed by more in-depth description of the challenges of joining the resulting panels as well as various alternatives for doing so. The alte...
Article
Full-text available
Flexible information exchange is critical to successful design-analysis integration, but current top-down, standards-based and model-oriented strategies impose restrictions that contradict this flexibility. In this article we present a bottom-up, user-controlled and process-oriented approach to linking design and analysis applications that is more...

... This map is obtained by representing on the plan this set of convex spaces delimited between the physical barriers of the building whether fixed or mobile. Initiatives for automatically generating convex spaces in the context of buildings (Carranza, 2013;Carranza and Koch, 2013 ), or 3D-informed convex spaces, also known as solid-voids, in the context of urban environment (Beirão et al., 2015;Beirão and Chaszar, 2014;Cavic et al., 2017;Sileryte et al., 2017), were studied and considered. ...
... The degree of command thereby is possibly very high, but it will likely be command by others, not designers. Nevertheless, digital technologies can contribute control to the processes of urban design representation, as noted above, and of sufficiently focused analyses, which need not be confined to purely technical performance but can also address matters of perception, such as assessment of 3D open urban spatial character via 'convex and solid voids' analysis [14,15]. Participatory design (collaborative and multi-or transdisciplinary) is becoming increasingly prevalent in addressing urban issues, and while not in itself a digital technology, much digital technology is be-ing put to service in realising it, to better marry design, analysis, communication and negotiation. ...
... Designers, and other stakeholders, including end users are to work together, and a web platform open for feedback enables such interaction to happen. With all who are involved working together in the cloud, we are one step closer to an ecology where creative human and computer cocreation in designing could be realized [15]. ...
... Similar attempts to generate option storing and comparison making systems exist, notability for parametric design systems by Zaman et al [9] which provides interesting features to automatically merge options creating a 'Cartesian Product' similar efforts have been explored by the author also [10] however these represent closed custom design systems with the model production and comparisons integrated in one monolithic package. It has been identified however that more open systems will enable greater ease and range of use [11] and shown by Dow et al that more sharing and comparison of options improves the results [12]. ...
... Digital fabrication technologies have also been strongly heralded and then lauded for enabling greater freedom, complexity and precision of manufacturing for architectural projects (including physical models / maquettes) as well as reducing time, cost and waste. Such technologies may in cases allow experimentation through physical prototyping and consequent extension of previous boundaries to 'non-standard' designs and construction methods, testing limits of complexity [12]. Control of fabrication by designers can also help overcome difficulties of finding willing and able builders. ...
... There is also a large body of literature focused on how to interpret generative design solutions, and to provide the user with appropriate workflows to modify and interact with the generated solution space (Scott et al., 2002;Herdy, 1996;Meignan et al., 2015). (Chaszar et al., 2016) explored methods and tools for multivariate interactive data visualization of the generated designs and simulation results by enabling designers to not only focus on highperforming results but also examine suboptimal ones (Mueller and Ochsendorf, 2015). Proposed a computational design exploration approach that takes advantage of an interactive evolutionary algorithm to integrate the designers' preferences within the solution search. ...
... Research on Generative Design started in the early 70s when the first design algorithms that mimicked nature were born [57]. Then, with the advent of parametric CAD tools, GD design was studied with a more practical approach, but only in the first decade of the century, when the first attempts of using GD in academic research for applications in the architectural fields were made [58][59][60]. Recently, thanks to the significant increase in computing power available, generative methods have begun to be adopted to the design of products [61][62][63]. ...
... In general, the degree of enclosure on a plane is widely used to describe the limitation effect of that enclosure (Robinson, 2004). Beirão et al. (2015) proposed spaciousness as an indicator of the overall enclosure effect influenced by both the area of the vertical boundary and the area of the domain: we refer to spaciousness as the comprehensive enclosure degree (CED) in this paper. However, this vertical enclosure feature cannot fully express the enclosed state of a space; as Stamps (2005Stamps ( , 2009Stamps ( , 2013 mentioned, the impression of vertical enclosure and the perception of spaciousness are also influenced by visual permeability. ...
... For instance, data acquisition, urban modelling, simulation and visualization tools can be linked so that a completely interactive exploration of design alternative becomes a reality. As Janssen et al. [3] mentions, this integration has to happen in a user friendly and flexible way to make this useful technology available to wider range of urban planners. He proposes a workflow configuration engine to manage tool collaborations within an urban planning pipeline (Fig. 2). ...
... However, in current AEC practices, we often encounter distributed interoperability across all layers where data is exchanged (Fig.1a), a centralized data schema across all disciplines (Fig. 1b), or federated interoperability where tools share an ontology that tools can relate to and refine (Fig. 1c). In the following subsections, we discuss distributed, centralized, and federated interoperability paradigms (adapted from [27]) in general, and provide an AEC application example of such interoperability. ...
