Summary: Since the 1930s, thermal comfort has been a crucial topic in the construction industry. The use of natural materials, including vegetal fibers or recycled waste products, is being explored to enhance thermal comfort in buildings. This study examines the origins and progression of thermal comfort concepts and evaluates the potential of integrating bio-based materials in building envelopes for maintaining thermal comfort. The findings suggest that alternative insulation materials made from unusual sources can compete with conventional materials and offer good thermal conductivity.
