summary	This paper discusses discrete computational design, discrete assembly logics and the discrete paradigm within the framework of architecture and construction. For the exhibition “Anonymized Exhibition Name” a large-scale exhibition structure was designed and assembled using discreteness as a guiding principle. The objectives of the discrete exhibition design itself were to exemplify a computational approach which is efficient and sustainable through its sequential assembly strategy and material choice, reducing material waste during the assembly and disassembly of the structure. To facilitate this, the realized exhibition design followed a discrete computational logic, based on the use of PERI construction scaffoldings as discrete building blocks. Wasp, a combinatorial toolkit for discrete computational design, was used for the design of this large-scale exhibition. The built exhibition structure, covering a space of 300 square meters with a total volume of 1200 cubic meters, can be considered one the largest structures built following discrete design principles through the use of the Wasp framework. The paper discusses the benefits of using standardized parts, without relying on new production lines, for a discrete aggregation logic, the strategy employed to determine the aggregation process, assembly and disassembly sequences. Additionally, the implications of using labor vs. automation for discrete assembly systems is contextualized and critically reviewed. As discreteness is one of the reoccurring themes in recent and current discourse on architectural design and theory, the paper additionally frames the discrete computational design strategies utilized within the ongoing debate. Through this, the notion of discreteness and its implementation within practice is discussed critically, addressing future implementation opportunities and challenges.

title	Parametric design and modular construction of a large additive-manufactured hypar shell structure

summary	Despite recent advances in additive manufacturing technologies, challenges remain to build 3D-printed structures at the architectural scale due to the high cost of large printing equipment. To address this challenge, modular construction has demonstrated its merit by making smaller prefabricated components and using on-site assembly. This paper presents a case study of a 3D-printed hypar shell structural art using modular construction. Guided by parametric design and structural analysis, we optimized the hypar shell to form a butterfly-like shape with a hollow-out pattern. The prefabrication of modular units was completed using commercial 3D printers to catch a limited production time. The prefabricated modular unit of the hypar shell was assembled on site for the Guangzhou International Light Festival, in which the lighting effect was added through the adjustable transparency of hollow spaces within the sandwiched panels. The 3D-printed hypar shell was also disassembled and rebuilt in the UK, showcasing the adaptability and flexibility of the modular design. The resulting 3D-printed structural art not only provides unique aesthetics for the built environment but also demonstrates the possibility of building large shell structures with a low budget by reducing complex falsework.

title	Characterizing the Solution Space of Building Shading System Through Computational and Parametric Feed-Forward Design Approach
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_24

summary	Building shading systems play an important role in controlling solar heat gains, which can mitigate the impact of climate change on indoor environment. Effectively reducing cooling demand in summer and heating demand in winter requests further development of seasonally regulated shading systems. The main problem is to find a way that consumes less energy while reaching better comfort, which demonstrates potential for conducting an extensive search to parametrize configuration of shading. This paper aims to investigate the effects of building shading systems on energy and thermal performance in different seasonal conditions through a parametric design method, using Baoshan station in Shanghai, China as a case study to establish a baseline model and test different shading components’ direction, depth, spacing, and tilt angle. The method explores a large solution space at the beginning of design, establishing a variety of approaches that can inform the architectural design team. The results showed that a proper passive shading system can reduce energy consumption by about 13% while thermal comfort meets ASHRAE 55 standards. This finding indicates the possibility of improving the indoor thermal comfort while lessening building energy consumption.
