title	Robotic 3D Printing of Mineral Foam for a Lightweight Composite Concrete Slab
doi	https://doi.org/10.52842/conf.caadria.2022.2.061
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. 61-70
summary	This paper presents the design and fabrication of a lightweight composite concrete slab prototype using 3D printing (3DP) of mineral foams. Conventionally, concrete slabs are standardized monolithic elements that are responsible for a large share of used materials and dead weight in concrete framed buildings. Optimized slab designs require less material at the expense of increasing the formwork complexity, required labour, and costs. To address these challenges, foam 3D printing (F3DP) can be used in construction as demonstrated in previous studies for lightweight facade elements. The work in this paper expands this research and uses F3DP to fabricate the freeform stay-in-place formwork components for a material-efficient lightweight ribbed concrete slab with a footprint of 2 x 1.3 m. For this advancement in scale, the robotic fabrication and material processing setup is refined and computational design strategies for the generation of advanced toolpaths developed. The presented composite of hardened mineral foam and fibre-reinforced ultra-high-performance concrete shows how custom geometries can be efficiently fabricated for geometrically complex formwork. The prototype demonstrates that optimized slabs could save up to 72% of total concrete volume and 70% weight. The discussion of results and challenges in this study provides a valuable outlook on the viability of this novel fabrication technique to foster a sustainable and resourceful future construction culture.

title	How Lay People Design Interior Architecture Layouts in Virtual, Augmented, Drawn and Physical Reality
doi	https://doi.org/10.52842/conf.ecaade.2022.1.411
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 411–420
summary	Simulated reality, such as virtual reality (VR) and augmented reality (AR), is particularly helpful for lay people such as clients or prospective occupants, as it allows them to first- hand experience an unbuilt architectural space to provide design input without the requirement of spatial expertise. However, as the experience of space depends on the holistic interplay of a wide variety of atmospheric aspects that cannot be easily simulated, it is still unclear how simulated reality influences lay people when making design decisions. Our study therefore captured how eight lay people designed the interior layout of the same room within five different simulated realities, including drawing reality, tabletop AR, mobile AR, VR and physical reality. By comparing the design process of two design tasks, we assert how each reality promoted or inhibited particular spatial qualities. Consequently, we propose that the realism of a reality influenced how people make design decisions based on atmospheric or functional considerations, the co-location of a reality provokes design decisions that neglect or include contextual factors, the accuracy of distance estimation in a reality depends on the availability of bodily references and the viewing frustum, the ability of a reality to compare design solutions instantaneously trumps the ability to interact with it more intuitively, and each reality comes with particular implementation costs against which the benefits should be estimated and offset. Our study thus provides actionable insights to choose the most appropriate simulated reality depending on the design goals, helps simulated reality developers to consider additional interactive features, and empowers lay people in taking an active part in architectural design.

title	Oyster Tiling: Augmented Ecological Topology
source	ACADIA 2022: Hybrids and Haecceities [Projects Catalog of the 42nd Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-7-4]. University of Pennsylvania Stuart Weitzman School of Design. 27-29 October 2022. edited by M. Akbarzadeh, D. Aviv, H. Jamelle, and R. Stuart-Smith. 160-165.
summary	Oyster Tiling is a study that blends material science, computational design, advanced fabrication, and restoration ecology to produce a tiling substrate for recruitment of functionally extinct Olympia oysters at Coquille Point on Yaquina Bay in Oregon. We utilized a design methodology with careful consideration of the intervention at the scale of Micro (material), Meso (topological), and Macro (tiling/ deployment).

title	Designing Out Heat ‚ Developing a Computer-Aided Street Layout Tool to Address Urban Heat in Existing Streets and Suburbs
doi	https://doi.org/10.52842/conf.caadria.2022.2.739
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. 739-748
summary	As cities are getting hotter, the urban heat islands effect will become an increased concern for cities. While urban heat migration strategies are well researched and understood, some strategies of implementing urban heat mitigation focus on private land - thus depend on the owner's uptake. This research shifts mitigation strategies to the public land where governments have legislative control over the corridor between privately owned cadastral ‚ the street corridor. This paper asks the question how a computational tool could assist councils in redesigning streets to mitigate urban heat. Literature review confirmed a direct relationship between the magnitude of urban heat and street layout, vegetation and materials used, position of street to sun and wind direction - yet no tool that assists a designer exists - the focus of the research. We present first findings and the iterative development of our street design tool. Via our tool one can alter variables such as vegetation type, materials or street configuration until urban heat mitigation is optimized. This is a significant step towards cooling our cities as designers now have a process that translates expert knowledge on urban heat into a tool that lets them design as well as evaluate their design.
