This lesson features Prof. Eike Roswag-Klinge (TU Berlin) and Prof. Andrea Klinge (FHNW and ZRS Architects Engineers), who share their extensive experience designing and constructing with nature-based materials such as timber, clay, and earth. They present real-world examples of low-tech, circular construction methods and discuss how traditional building knowledge can meet today’s sustainability and climate goals.

Through case studies, they explore how regenerative materials, flexible construction systems, and dismantlable designs can reduce carbon emissions and resource consumption. The lesson also addresses the challenges posed by current building regulations, especially in Germany, and offers insights into the future of architecture within planetary boundaries. Learn how innovation, reuse strategies, and circular thinking are transforming the construction industry toward a zero-emission future.

IN THIS LESSON:

  • Motivation: The Current Situation in Construction in Germany

  • Principles of circular, low-tech building systems

  • Reversible Design for a School Extension in Berlin

  • The life cycle assessment of natural materials

  • A deep dive into the Timber Brick Earth concept as a regenerative construction solution

  • Timber Brick Earth: Research-Based project

  • Real-World Laboratory: Museum Pavilion in Berlin

  • Scaling Up Timber Reuse and Innovation

  • Legislation and Public Acceptance

Prof. Eike Roswag-Klinge and Prof. Andrea Klinge respond to questions from the audience, diving deeper into the technical and systemic aspects of sustainable building practices.

The discussion touches on material safety, climate adaptability, and the broader challenges of transitioning to low-impact construction.

KEY TOPICS:

  • Fire safety and performance in timber buildings

  • Thermal insulation standards and solutions

  • The role and regional feasibility of wood as a primary construction material

  • Limitations and lifecycle impacts of concrete

  • How to align innovation with legislation and climate goals

In the German Experience Part 2 lesson, Sina Jansen and Julian Mönig from the Natural Living Lab at the Technical University Berlin present their research on waste-wood value chains and circular construction strategies, highlighting how waste wood can be transformed into valuable building materials, supporting a resource-efficient and climate-conscious construction industry. Also, this lesson introduces the Natural Living Lab’s approach to research-based architecture and dives into the environmental, technical, and legislative dimensions of waste-wood reuse. You can also learn about the examples from ongoing demonstration projects that showcase circular design principles in action.

IN THIS LESSON:

  • The mission and methods of the Natural Living Lab

  • Waste management legislation and its role in the built environment

  • Challenges to adopting circular construction in practice

  • A breakdown of real-world projects piloting waste-wood solutions

  • Broader insights into earth-based construction techniques and material reuse
