Mycelium is a sustainable, low-impact material that civil engineers are increasingly exploring to improve building efficiency. By combining agricultural waste with fungal hyphae, this material is grown into a lightweight and sturdy composite.1

When utilized as building insulation, mycelium-derived materials can reduce a structure's long-term energy consumption. By providing effective thermal insulation, these materials help maintain stable indoor temperatures, which directly lowers the energy required for heating and cooling systems. This application aligns with the broader goal of sustainable development in civil engineering, where the focus is on mitigating the environmental impact of construction projects through the use of innovative, low-energy materials.1
