The building sector is a significant contributor to global energy consumption, driving the need for innovative and sustainable energy efficiency solutions. This study investigates the potential of integrating bio-composite phase change materials into building envelopes to improve thermal performance and reduce energy demand. A novel bio-composite phase change material was developed, and its thermal properties, including latent heat capacity and melting temperature, were characterized through laboratory testing. The material was then incorporated into a virtual building model using energy simulation software to evaluate its impact on thermal loads and overall energy consumption. The results demonstrate that the bio-composite phase change material effectively reduces peak heat flux and provides a significant thermal lag, leading to an estimated 15%–20% reduction in annual heating and cooling energy use compared to a conventional envelope. A preliminary life cycle assessment also indicates that the bio-composite offers a more environmentally friendly alternative to synthetic phase change materials. This research highlights the viability of using renewable, bio-based materials as a passive thermal management strategy, paving the way for the development of more sustainable and energy-efficient buildings.Keywords: Bio-based insulation, building envelope, energy efficiency, sustainable construction, adaptive materials
