title	From Analog to Digital: Double Curved Lightweight Structures in Architectural Design Education
doi	https://doi.org/10.52842/conf.ecaade.2020.2.181
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 2, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 181-188
summary	The paper describes an architectural design studio for 5th year students at the Department of Architecture of the Aristotle University in Thessaloniki, Greece. The educational objective of the studio is the design of double curved lightweight structures, employing a creative methodology which instrumentalizes the study of nature as a source of inspiration. The objective of the course is to familiarize the students with curves and form-finding (analogue and digital) with the aim to design forms that display structural stability. The paper will highlight the educational gains from a hybrid design methodology which employs both analog (physical) form-finding tools and digital modeling for the design of double curvature surfaces.

title	Teaching Digital Design Principles to First Year Design Students - A methodology based on direct experimentation with physical construction assemblages
doi	https://doi.org/10.52842/conf.ecaade.2020.2.127

summary	An educational methodology is presented that introduces basic digital design concepts to first year design students. The methodology differentiates between four fields in design thinking namely Form, Function, Context, and Structure/Materiality and focuses on Structure/Materiality that is approached as an assemblage of components. Components are categorised in respect to their geometric and structural qualities with reference to the elements of 'point', 'line', 'surface' and 'volume'. Components are interconnected to corresponding design techniques that are used in order to compose complex forms and are outlined by a rule of composition. The primary technique of 'point' structures is based on the notion of multiplicity and repetition. 'Line' assemblages introduce to the concept of load bearing structures and they can effectively describe hierarchical associations. 'Surface' elements are used to explain the results of transformational processes upon structural behaviour. 'Volume' techniques refer to the notion of integration and directly affect the overall performance of the structure. For each one of these elements, the students are asked to work directly on physical assemblages with ready-made components which are chosen in respect to their structural characteristics and to describe explicitly the whole process in drawings and diagrams.

summary	In this paper, we explore conditional generative adversarial networks (cGANs) as a new way of bridging the gap between design and analysis in contemporary architectural practice. By substituting analytical finite element analysis (FEA) modeling with cGAN predictions during the iterative design phase, we develop novel workflows that support iterative computational design and digital fabrication processes in new ways. This paper reports two case studies of increasing complexity that utilize cGANs for structural analysis. Central to both experiments is the representation of information within the data set the cGAN is trained on. We contribute a prototypical representational technique to encode multiple layers of geometric and performative description into false color images, which we then use to train a Pix2Pix neural network architecture on entirely digital generated data sets as a proxy for the performance of physically fabricated elements. The paper describes the representational workflow and reports the process and results of training and their integration into the design experiments. Last, we identify potentials and limits of this approach within the design processes.

summary	Improving speech intelligibility in classrooms enhances information dissemination, institutional knowledge capture, and quality of learning experience. While off-the-shelf solutions are available for acoustically retrofitting existing learning spaces, they do not allow for a fine-tuned context-specific intervention. However, this possibility is enabled through bespoke digital manufacturing informed by advanced digital simulations. In this research we explore and synchronize architecture, acoustics, computation, and fabrication for the making of better sound environments. We present performance-driven design-to-manufacture (DTM) workflows for sound-scattering brick elements. We reimagine the brick as an acoustically active geometry capable of modulating the sound experience in a university classroom by improving speech intelligibility. We contextualize our research within existing methods of digital performance-based design and robotic fabrication processes, namely wire cutting and pick-and-place applications. We then detail digital methods that combine heuristics and acoustic simulation to design the bricks within the 3D modeling environment, as well as describe the processes of robotic oscillating wire cutting and adaptive pick-and-place developed for the execution of the full-scale demonstrator. Finally, we report on the results of the acoustic analysis performed on the full-scale demonstrator in situ and laboratory measurements of a representative demonstrator which validates our design hypothesis.
