This interactive workshop introduces students to sustainable construction strategies through the lens of bio-based materials and Life Cycle Assessment (LCA). Participants will explore how material choices influence embodied carbon, circularity potential, and long-term environmental performance. Structure and Interactive Elements: Short introductory lecture on sustainability metrics in construction (embodied carbon, LCA stages, circular design). Case-study analysis in small groups comparing conventional vs. bio-based material solutions. Group discussion on trade-offs between structural performance, cost, and environmental impact.
