Thermal Solutions for Green Buildings

BIOBUILD aims to reduce up to 20% of energy demand in buildings. The project develops thermal solutions for energy efficiency in buildings using fully bio-based building materials. These novel materials are fully recycable and sustainable, driving a rapid transition towards decarbonisation across major industrial sectors.


Challenge


The impact of fossil fuels on energy consumption in buildings highlights the urgency to transition to renewable energy sources and sustainable construction practices. In the EU, buildings account for 40% of energy use, 36% of greenhouse emissions and about 95% of the binders used in wood-fibre composites are fossil derived. Fossil fuels such as coal, oil and natural gas have traditionally been the primary sources of energy for heating, cooling and electricity generation in buildings. Non-biobased materials such as bricks, concrete, plastic and glass have high environmental footprints and limited recycling possibilities. Their widespread use contributes significantly to overall energy consumption.

Solution


BIOBUILD is paving the way towards green buildings with improved thermal performance. The project focuses on bio-composites as environmentally friendly building materials with additional functionalities for energy storage. This innovative approach will integrate Phase Change Material (bioPCMs) into solid wood and fibers bound together by plant oil resins, lignin and fungal mycelium. The BIOBUILD project will design and showcase protype wooden houses with innovative wallboards and parquet in Sweden and Spain. It will additionally evaluate energy saving performance and recyclability options.

Impact

BIOBUILD will have positive environmental and socio-economic impacts by strengthening and expanding the bio-based economy.

BIOBUILD is expected to have:

  • Improved thermal comfort of occupants and 20% reduction of energy demand
  • Increased use of formaldehyde-free binders and reduced VOCs
  • Wider use of bio-based materials and wood-based products in buildings
  • Decreased use and dependance on fossil-based products in construction
  • Reduced environmental footprint and maximised resource efficiency in the construction industry
