CETP - Innovative bio-based building materials with thermal energy storage function

MYCOBUILD aims to make environmentally friendly building materials with superior thermal properties. We will only use bio-based masterials in our composite materials, which will contain mycelium (the root-like structure of mushrooms), fibers produced from wood, and bio-based phase change materials (bioPCMs). The bioPCMs are able to store energy in the form of heat by taking up energy when it is warm, and releasing it back when it becomes colder. We aim to enhance thermal storage while maintaining material strength, durability, and sound insulation. We will also utilize a digital integration approach, life cycle assessment (LCA) for sustainability, circularity, and safety, alongside socio-economic impact analysis and stakeholder engagement. Preliminary LCA on the use of mycelium as a binder in building materials have been conducted, and models for energy simulation of how the new materials will affect a model house is under development.

MYCOBUILD, an innovative bio-based project, targets transforming the construction sector with sustainable materials offering thermal energy storage. It aligns with Europe's 2050 climate-neutral goals, focusing on bio-based, multifunctional materials for an eco-friendly market impact. MYCOBUILD's core is bio-based phase change materials (bioPCMs) in lignocellulosic fibres, using fungal mycelia to create superior thermal property bio-composites. It progresses from conceptual proof (TRL3) to industrial demonstration (TRL6), meeting CETPartnership's 2023-06 “Heating and Cooling Technologies” call. The project leverages lignocellulosic structures as bioPCM storage for energy-efficient building products. Aiming to enhance thermal storage while maintaining material strength, durability, and sound insulation, the project spans from product development to construction models in key technologies (TRL6). Objectives include benchmarking, optimizing bioPCM integration, producing fungal bio-binders, demonstrating wallboard materials, and evaluating energy-saving constructions in various European countries. It also involves a digital integration approach, ex-ante life cycle assessment for sustainability, circularity, and safety, alongside socio-economic impact analysis and stakeholder engagement
