Recycled Aggregate Concrete Structures: Design and Life Cycle Analysis

Construction and demolition waste (CDW) accounts for over one third of the waste
produced in the European Union (EU27) and the sector of aggregates for construction is
the world’s largest non-energy extractive sector worldwide. Therefore, recovering CDW
as recycled aggregates for concrete is a sustainable option for the construction sector, in
full compliance with the European Union’s Circular Economy Action Plan.
The motivation of the Symposium is the analysis and demonstration of structural-and
resource-efficient structural systems. Hence the scope covrs structural analysis, testing
and environmental analysis through comparative life cycle assessment (LCA).

Sessions:

  • Structural Design of Recycled Aggregate Concrete Structures
  • Life Cycle Analysis of Recycled Aggregate Concrete Structures

The Detail as the Convergence of Structure and Architecture: History, Theory, and Articulation

This session investigates the architectural detail as a site of collaboration and invention between the disciplines of architecture and structural engineering. Far from being a purely technical component, the detail represents a microcosm of larger disciplinary relationships: it is where conceptual intent meets material behavior, where structural logic becomes visible, and where technological innovation acquires cultural meaning. By foregrounding the detail, this session invites contributions that reveal how architecture and structures co-produce form, performance, and expression. This session welcomes academic and practice-based research related to past or present instances of details representing building concepts based on technological innovation, material studies, or formal trends

Architectures and Structures of Planetary Alliances: Common grounds for Collective Forms of Inhabitation.

This session explores how we can utilize our diverse perspectives to address global and local challenges while respecting planetary boundaries. In this matter, we seek the principles of deep, transformative collaborations across diverse voices from different parts of the globe, enabling us to embody collective knowledge and explore alternative methods and practices of collaboration to conceptualize and build collective forms of inhabitation.
We ask: Is it possible to define local frameworks of collaboration that serve as indicators for establishing planetary alliances? How can our design processes incorporate diverse voices and contexts, both in structure and form, to support a range of identities and senses of place?
To broaden perspectives, we encourage contributions from three different areas of collective spatial practice, building upon our common interdisciplinary ground as architects and engineers:
• Historical Engagements: Practices that reexamine past approaches to social and ecological responsibility in the making of the built environment, drawing inspiration for addressing contemporary challenges.
• Hybrid Practices: Practitioners conducting research across regions, translating experiences and knowledge between different geographies, climates, and material traditions, who collaborate to create a civic building culture.
• Collective Movements: Those engaged directly with communities and local initiatives to advance social, spatial, and ecological justice, addressing issues such as climate justice, migration, resources use, housing, and labour.

Conceptual Structural Design with Reused Components

Conceptual structural design with reused components is driven by the constraints imposed by a given stock of existing material, including fixed geometries, quantities, and mechanical properties. Form-finding, shape optimization, and topology optimization provide powerful conceptual tools to generate structural configurations that operate within these limitations rather than assuming new material availability. By adapting form, load paths, and structural topology to reusable elements and constrained boundary conditions, these methods support early-stage design exploration under uncertainty. This special session invites contributions on constraint-driven form-finding and optimization approaches that enable structurally effective and circular reuse of existing material stocks.

Circular Assemblages: Reframing Circular Reuse as a Cultural and Aesthetic Practice

Circular construction approaches in architecture and structural design often prioritize material efficiency and technical optimization, overlooking cultural, spatial, and experiential dimensions of reuse. Circular Assemblages proposes reuse as a design-driven practice in which reclaimed components and systems operate as active agents shaping structural logic, architectural expression, and meaning. Building on debates around structural reuse, the session explores how emerging technologies and design methodologies can integrate technical performance with cultural and aesthetic value. Contributions critically examine circularity as a design logic that negotiates material continuity, structural agency, and aesthetic transformation within contemporary built environments.

New Philosophies of Structures for Material Circularity

This special session focuses on the poetics and philosophies of structures, rethinking their meanings and transformations in the context of circular construction. As material rationale, e.g., minimum material usage and design from/for reuse, becomes essential in architectural and structural design process, the driving design philosophies and their tectonic expressions are also profoundly influenced. How do the principles of material circularity reshape design? This session invites contributions that examine, based on and/or extending beyond scientific calculation, the interplay of form, force, construction approach, tectonics, and human perception through the lens of material circularity, exploring its potential to enrich architecture not only technically but also philosophically and artistically.

New paradigm in structural Steel Design embracing reuse and circularity

Within the circular economy framework, reuse represents a more sustainable alternative to recycling, as it substantially reduces both reprocessing energy and construction waste. Designing structures using reclaimed components—or conceiving new structures for future disassembly and reuse—introduces significant technical challenges, requiring a fundamental rethinking of the conventional design workflow as a reversed design paradigm. This session aims to foster discussion and knowledge exchange on reuse-oriented structural design. Contributions are invited on applications such as frame structures for multistory buildings, as well as gridshell canopies, diagrid exoskeletons, industrial sheds, and space frames. Two main thematic areas are identified: design strategies based on reclaimed components, and design strategies enabling future disassembly and reuse. Submissions may address aspects such as structural efficiency, constructability, environmental and economic performance, technical protocols and experimental tests, standards and codes, real-world case studies.

Waste-Based Additive Manufacturing for Performance Optimization and Architectural Aesthetics

The adoption of recycled and waste-based materials in construction raises critical questions regarding structural performance, while opening new possibilities for architectural expression within the framework of circular economy. Additive manufacturing allows elements to be conceived simultaneously as load-bearing elements and architectural components. With the integration of waste-based material, additive manufacturing can also contribute to the development of circular solutions. Attention can be given to rheologically controlled dense-fluid materials, such as concrete, rammed earth, and other natural materials, including reused materials and process by-products. This special session brings together experts working on waste-based additive manufacturing to discuss how material behaviour, structural performance, and architectural expression can be co-designed through digital fabrication. Emphasis is placed on integrated design-to-production workflows, experimental validation, and  in demonstrating how computational form optimization enables a significant reduction in material use while enhancing structural and energy performance.

From Forest to Future: Sustainability in Timber Architecture and Construction Beyond Circularity

The concept of sustainability has evolved from its early associations with forest resource balance to now encompass circularity, resilience, and regenerative design. Moreover, in the face of accelerating climate challenges, advancing a sustainable and equitable architecture and construction sector requires transdisciplinary engagement across material innovation, building technologies, digital tools, and sociocultural considerations. This session looks beyond circularity towards a future in which timber enables buildings to repair, adapt, and transform over time. It explores innovative design strategies, construction systems, and digital tools that support extended service life of buildings, material value retention, climate responsiveness, and sociocultural impact in timber architecture and engineering.

Stone structures: investigations on natural stone as a load-bearing material in contemporary design practice

In the past century, the role of natural stone in the construction industry was often limited to gardens and water structures, mere ornamentation or cladding purposes. The emergence and development of new structural materials such as reinforced concrete was among the causes that determined a gradual shift away from natural stone as a load-bearing construction material. However, a re-evaluation of the role of natural stone in contemporary design practice could prove valuable, also considering the pressing issues connected to the decarbonisation of the constructing industry. This session fosters a re-examination of natural stone through the lens of circular economy and interdisciplinary design approaches. We encourage applicants to propose contributions that illustrate contemporary use of natural stone, with a particular focus on its structural applications. The session will explore state-of-the-art strategies resulting from critical inquiries into the following macro-areas: Resource Availability: The specific occurrence and geological properties of local stone. Process: Innovations in quarrying, digital fabrication, and stereotomy. Application: New structural systems, connections for disassembly, and retrofit strategies.

Designing Curricula

As architects and engineers revise practices to respond to environmental and social challenges, faculty, too, are redesigning curricula to educate students to become changemakers in the building industry. A commitment to circularity and integration of structural and architectural skills suggests examination beyond a single course. This session invites research on historic, current, and speculative curricula that demonstrate comprehensive approaches to reassessing architecture or engineering education. Reflection on conceptualization, processes, highlights, hurdles, disciplinary boundaries, skill building, critical thinking, and implementation are welcome. We hope to learn from analyses of curricula either in development or to reflect on successes and missteps.

Closing the Loop: Context-aware robotic agency in robotic material structural systems

Moving beyond the paradigm of rigid, pre-programmed automation, this session critically examines the emergence of embodied intelligence in robotics used for architectural and structural tasks. We frame survey-to-production as a continuous, iterative cycle where AI-driven perception and sensor-enhanced decisions enable “situated cognition” – the ability of robots to perceive and adapt to the complexities of the physical world through sensing, scanning, vision systems, or other data acquisition techniques. As we transition from blind fabrication to context-aware agency, this session invites research on adaptive workflows that bridge digital construction and deconstruction. Fundamental questions arise: How does enabling robots to “see” and “sense” alter material (re)use and structural assembly? How do we evolve from mere execution to intelligent, adaptive interaction?

The session explores how hybrid manufacturing and generative AI enable structural systems whose performance evolves through material agency, data-driven processes, and feedback loops. The session focuses on experimental and hybrid manufacturing strategies that activate regenerative behaviors through fabrication, material interaction, and circular construction logics. Moreover, work examining how generative AI reshapes function through adaptive learning, predictive models, and emergent performance is also considered. Together, the sessions position structures as active, regenerative systems within cross-disciplinary structures and architecture research.

Rethink Wood: Resources, uses and potentials in a changing world

Wood is often presented as the sustainable solution. But like other materials, it is not an inexhaustible resource. The climate is changing, and access to known resource streams is uncertain. If wood is to be a material that truly disrupts the architecture and construction industry, we must rethink the types, conditions, and species of wood we use. This special session explores alternative wood resources, new silvicultural realities, and design strategies that respond to ecological limits. By addressing scarcity, diversity, and material intelligence, the session aims to reposition wood not as a default solution, but as a critically informed architectural material.

Circularity & Caring Sensibilities: Shaping design processes that are both responsible and responsive

The perspective of Care is gaining increasing recognition across urbanism and architecture as an ethical and empathic design response to pressing planetary challenges. This approach promotes inclusive design and just societies within a more-than-human world. While significant theoretical insights have emerged, practical methods and design sensibilities remain underdeveloped compared to established approaches such as life-cycle assessment and structural evaluation. These two sessions aim to foster contributions that explore design methodological frameworks and bridge the gap between theory and practice. The focus is on demonstrating how caring sensibilities can inform and inspire circularity – shaping design processes that are both responsible and responsive

Integration of LCA and circularity in the design and construction of buildings

The architecture, engineering and construction (AEC) sector is expected to gradually move toward decarbonization and circularity in line with European policies. Life Cycle Assessment (LCA) is indicated as a reference method to support design and construction choices in this direction. To integrate LCA into building design and construction practices, it is necessary to provide policymakers, designers, and contractors with LCA methodological guidelines, tools, shared databases, and establish environmental benchmarks to be achieved. This Special Session highlights current best-practices intersecting structure and architecture, that demonstrate how AEC sector is moving towards LCA and circularity, focusing on policy, market and professional developments.

Grounding flows: from the building to the city and back again

The circular economy has gained traction in the construction sector as it offers a model for both maximising the reuse and recovery of materials and redefining the built environment as a closed-loop system. However, frameworks for collecting and monitoring data on the quantity and quality of materials from (de)construction sites remain unsystematic and largely based on a case-by-case basis. In this special session, we invite reflection on the broad potential for situating (de)construction data in context across European cities to support appropriate interventions for the implementation and upscaling of circular strategies in new constructions.

Umbau as Circular Structure: Adaptive Reuse between Typology and Affordance

Transformation and adaptive reuse (Umbau) demand a rethinking of structure not as a fixed technical support, but as a performative and typological framework for change. This session investigates Umbau as a centrally circular design intelligence operating between structural persistence and spatial reprogramming. Drawing on affordance theory, typology, and embodied experience, contributions examine how existing structures guide, enable, and negotiate use without strict determination. Structure is approached as an open script – durable yet adaptable – balancing normative form and temporal occupation. Bringing together architectural theory, design research, and built work the session frames reuse as a critical, ecological, and materially grounded circular practice.

Circular hybrids for low-carbon buildings. Multi-stream material reuse in the re-design of structures and envelopes

This session gathers research and design experiences exploring hybridization among circular materials of diverse nature for structures and envelopes. It collects investigations on performance-driven multi-stream reuse strategies, where salvaged timber, steel, concrete, masonry, and bio-based materials are integrated into circular, low-carbon systems. Contributions showcase design methodologies addressing circular construction techniques for mixed reclaimed components, validating hybrid assemblies – within structures and envelopes – including secondary materials coming from different sources and value chains. The session thus documents how designers and researchers navigate compatibility challenges between different salvaged materials, develop reversible connection systems, and achieve structural-architectural integration maximizing resource efficiency and decarbonization at the building level. By sharing experiences in mixing diverse circular material streams, it advances systematic approaches to embodied carbon reduction and demonstrates viable pathways toward regenerative construction practices. Thus, the session directly aligns with ICSA2027 Circular + scopes, especially with the topic Advanced Material & Design Innovation.

Pop-up Structures for Culture. Contemporary Construction History between Technological Innovation, Architectural Language and Sustainability

The session examines temporary structures designed for exhibitions, museums, cultural events, and heritage contexts through the lens of contemporary construction history, focusing on the period from the second half of the twentieth century to the present. It explores how sustainability-driven concerns—such as reversibility, reuse, material efficiency, and lifecycle awareness—have shaped construction processes and architectural and structural language. Temporariness is interpreted as a laboratory in which technical choices and expressive forms are closely intertwined. Attention is given to historical case studies that highlight good design and construction practices, offering critical insights for future sustainable approaches.

Energy Transition in the Built Environment: From Vision to Urban Practice

As cities confront the urgency of climate mitigation, the urban energy transition is becoming a central driver reshaping how the built environment is designed, constructed, and transformed. Yet implementation remains hindered by regulatory constraints, fragmented governance, financing challenges, and persistent gaps in urban data needed to support informed decision-making. This special session invites contributions examining how energy planning practices can embed circularity, efficiency, and life-cycle thinking while overcoming real-world implementation barriers. Through diverse perspectives, the session aims to gather evidence, methods, and design approaches that support scalable, resilient, and energy-responsive urban transformation.

Reclaiming the Unfinished - Architectural Design and Structural Strategies for Circular Reuse

This Special Session investigates the processes that have led to the unfinished condition of large architectural complexes, often abandoned or underused, and explores methods, tools, and techniques to reclaim them as strategic resources. Drawing on the experience developed in a shared design studio between the Politecnico di Milano and ENSA Paris–Val de Seine, the session promotes an interdisciplinary dialogue between architectural design, structural engineering, and construction process technologies. Contributions address adaptive reuse, strategies of subtraction and addition, structural rehabilitation, and material reuse within existing contexts characterized by large unfinished structures. Through academic research, design experimentation, and built case studies, the session discusses how unfinished architectures can be reactivated as resilient, low-impact spatial systems, contributing to sustainable cities and communities in line with Circular+ principles.

Integrated bio-based approaches to energy and seismic retrofit of the building stock

As many regions worldwide face the dual challenge of seismic risk and climate change mitigation, the retrofit of existing buildings is emerging as a strategic priority for enhancing resilience and sustainability within the built environment. However, interventions often address structural safety, energy performance, and environmental impact separately, leading to fragmented solutions and missed opportunities for systemic improvement. This Special Session invites contributions exploring integrated retrofit strategies that simultaneously enhance seismic performance and energy efficiency while reducing life-cycle environmental impacts. Particular emphasis is placed on approaches that prioritize low-carbon and bio-based materials, resource efficiency, and circular design principles, aiming to avoid additional embodied emissions associated with conventional strengthening techniques.
