Concepts embedded in circular design, such as building adaptation, design for disassembly, and material reclamation, see digital modelling and computation as an essential infrastructure. How can the role of computation in this realm be explored beyond mere asset management? In Area A: Realising Circular Design, we invite therefore papers that reflect on one or more of the following topics:

• Advanced modelling techniques that integrate circular economy principles into sustainable architecture, product, and systems design. 
• Optimising the reuse of materials and components, as well as modular and design for disassembly strategies. 
• Performance-based design driven by multi-criteria optimization will be explored to balance sustainability, cost, functionality and structural behaviour. 
• Machine learning algorithms play a critical role in predicting material behaviour and resource flows, while learning from experiments and failures to drive iterative improvements. 
• Novel computational tools help to assess the environmental impact at all stages of the design process through comprehensive Life Cycle Analyses (LCA). 
• In addition, we invite contributions that evaluate the potential of emerging technologies in circular design, assessing their sustainability, resource efficiency, and innovation impact.
• investigate structural design and form-finding with a given material stock.

In this subtopic, we aim to highlight how computational tools and digital modelling can advance circular design concepts and play a critical role in improving environmental assessment and innovation. This exploration paves the way for a more sustainable, resource-efficient, and innovative future by catalysing transformative design practices that align circular economy principles with cutting-edge modelling techniques.

Area B: Scaling Digital Concepts in Construction offers an exploration of the complexities involved in scaling digital concepts in the construction industry. We invite contributions from research and architectural and engineering practice that encompasses one or more of these aspects: 

• The industrialization of novel, disruptive construction processes and their evolution from theoretical concepts to practical, scalable solutions.
• Transitioning architecture into Industry 5.0 : addressing the social dimensions of scaling digital concepts, considering their impact on work practices, worker skills, and the socio-economic dynamics of the construction sector. 
• A critical analysis of failures and problems encountered in the development of digital construction approaches, highlighting lessons learned and opportunities for improvement.  
• The transition of digital concepts from laboratory experimentation to large-scale industrial adoption, including shifts from small robotic applications to large-scale deployment. 
• AI-based image and design generation, and its integration into the design and production workflow.
• The role of resource availability in the successful scaling of digital construction concepts, including physical resources, funding, and technological infrastructure. 
• Exploration of barriers to the implementation of promising digital construction processes, including technology readiness and regulatory challenges.

By examining the interplay of technological innovation, societal factors, and resource considerations, we seek to address the fundamental question of why certain digital construction processes have not achieved widespread adoption despite their potential. Through critical analysis and interdisciplinary discussion, we aim to pave the way for more effective strategies to bridge the gap between digital innovation and on-site implementation.

Within the area C: Biomaterial Design, we ask for contributions that delve into the profound impact of innovative materials on the landscape of sustainable design. Contributions to this multifaceted domain can encompass one or more of the following key facets: 

• The strategic utilisation of renewable resources, such as willow, bamboo, clay, mycelium, and algae, within design processes, highlighting their intrinsic versatility and ecological resonance. 
• Materials customization and design for growth, where materials are tailored to precise specifications. 
• Extensive research into material properties, and novel methods of computational material simulations. 
• Bottom-up design approaches, originating from the inherent characteristics of materials and subsequently informing innovative building design strategies.
• Speculative material explorations with successful discoveries and failures
• Develop and characterise biomaterials for their structural capacities.

This subtopic requires highly interdisciplinary workflows between designers, biologists, chemists, roboticists, programmers, and material designers, and therefore seeks to create a platform for them to present ground-breaking research, methodological advances, and pragmatic applications. These contributions collectively advance the frontiers of sustainable and environmentally conscious design practices.

Industry 4.0 has introduced the concepts of digitization and automation, signifying the transformation of manual processes into digital ones. While these principles have found success in various industries, the construction sector has exhibited resilience to their adoption. Recent advancements have propelled us from mere „digitization“ to the realm of entirely digitally-driven, novel construction processes that are no longer feasible to execute manually. In this context, we invite submissions that explore one or more of the following topics:

• Delve into the utilisation of robotics and drones in construction, focusing on their roles in automating and enhancing various aspects of the construction process, from site assessment to building assembly. 
• Explore the application of augmented reality in the construction industry, examining how it aids in visualisation, design validation, and on-site project management. Investigate the transformative shift from traditional digitization to fully digital construction processes. 
• Analyse how this transition reshapes project execution and delivery. Examine the use of additive manufacturing (3D printing) in construction, both for creating building components and for on-site construction tasks. 
• Explore the role of machine learning algorithms in optimising fabrication processes within the construction sector, enhancing efficiency and precision. 
• Investigate the implementation of kinematic principles and multi-robot systems in construction, assessing their impact on tasks like site logistics, assembly, and maintenance.
• Critically test the scalability of new technologies for their application in the building industry.

Submissions in this area should shed light on how these emerging technologies are catalysing a profound shift from traditional construction methods to digitally-driven, innovative processes. We invite contributions that elucidate the challenges, opportunities, and transformative potential of these advancements in the construction industry.
