Resource-Efficient Structural Design (REStructureD)
The Resource-Efficient Structural Design (REStructureD) project aims to develop a scientific basis for a paradigm shift in structural engineering — moving away from inefficient, generic, and linear design approaches toward tailor-made and circular design methods. This transition is essential for minimizing material use, life-cycle costs, and greenhouse gas (GHG) emissions, while ensuring compliance with all relevant structural performance requirements.
Objectives
The project seeks to:
- Establish a risk-informed, multi-parametric design framework for both new and reclaimed structural components.
- Develop methodologies to maximize the benefit of available information for condition assessment of reclaimed materials, enabling their confident reuse.
- Create digital tools and demonstrators to facilitate the application of resource-efficient structural design principles in practice.
Background
Structural design standards play a crucial role in determining the resource consumption and environmental impact of the built environment. However, existing design codes often overlook the potential of circular strategies, leading to excessive material use. REStructureD integrates advanced Bayesian statistics, risk-informed decision-making, and parametric design to optimize structural performance while reducing waste and carbon footprint. Comparisons with traditional rule-based design indicate a saving potential of 10–30% material per structure.
Impact
By addressing current inefficiencies in structural design, REStructureD contributes to key UN Sustainable Development Goals (SDGs), including:
- Climate action (SDG 13) – Reducing the environmental impact of the construction sector.
- Sustainable cities and communities (SDG 11) – Promoting resilient and resource-efficient buildings.
- Responsible consumption and production (SDG 12) – Enabling circularity in construction materials.
Collaboration
The project is a collaboration between NTNU and SINTEF, with interdisciplinary input from structural engineering, material science, environmental sustainability, and digitalization. It also aligns with ongoing efforts in Circular Economy and sustainable construction research.
