Optimisation 

Upscaling of Technology for bioPCM Integration

BIOBUILD aims to improve and expand the physical incorporation of bioPCM into the parquet and wallboards through impregnation. The project aims to achieve the following optimisation objectives:

  • Select between thermal or microwave pre-treatment of solid wood to optimise the bioPCM uptake and minimise leaching, while thermal modification will be used for fiber pre-treatment
  • Develop scalable technology for bioPCM impregnation into solid wood boards and wood fibers focusing on optimising the bioPCM retention
  • Employ modeling and quality control techniques including microscopy to quantify the penetration of bioPCM into fibers

Upscaling of Three Bio-binders

BIOBUILD aims to upscale the production of three binders for wood particles and fibers hosting bioPCM. Specifically, it aims to:

  • Optimise the production process of binders based on plant oils and lignin
  • Manufacture panels containing bioPCM using mycelium-based binders with fast growing fungal strains
  • Assess the compatibility of fungal strains colonising bioPCM fiber surfaces
  • Optimise and set a semi-pilot production of the selected bio-binders

Optimisation, Environmental and Economic Performance Assessment

BIOBUILD will perform advanced dynamic building performance simulations to assess the operational efficiency and occupants’ thermal comfort in diverse settings. These simulations will play a pivotal role in selecting the optimal material properties of bioPCM relative to specific climatic conditions and will generate energy consumption data throughout the operational phase for Life Cycle Assessment (LCA).

This comprehensive assessment, which considers insights into production processes and recyclability at the end of the product’s service life, is essential for evaluating the environmental footprint of innovative bio-based solutions for thermal energy storage in buildings. These results will be integrated within a multi-criteria assessment (MCA) including Life Cycle Cost Assessment (LCCA); to propose suitable business models for commercial exploitation of the product and related services.

The environmental and economic performance evaluation will utilise cutting-edge open-source assessment tools along with proprietary and public datasets and software tools/ dynamic building energy performance simulation (BEPS) will be used to model thermal flows within buildings, as well as to assess occupant thermal comfort and energy demand for heating and cooling.

LCA models will be developed using established and recognised methods, as well as innovative prospective approaches to estimate environmental impact at an industrial scale based on lab scale information only. The LCA will follow the guidelines of the ILCD Handbook and the ISO standards 14040-14044.
