Important results from the project
The goals of knowledge enhancement and increased acceptance were met; all parties are well prepared and several are preparing to implement bio-based building envelopes. The sharing of tests/pilots between parties accelerated spread and increases credibility in the industry. An important added value is the increase in knowledge in sustainable construction, with upcoming limit values for climate impact for buildings, the market for bio-insulation is ready to shift up.
Expected long term effects
The project is expected to provide a lasting knowledge boost, increased acceptance and a reduced sense of risk. Verified pilot projects lower the threshold for implementation, drive demand for bioinsulation, enable scale-up and lower costs for material manufacturers. The basis may contribute to certain market segments wanting stricter (lower) limit values for climate impact and strengthened competitiveness for wooden houses, with the spread also to site construction and other frame materials.
Approach and implementation
The project was carried out in three stages: 1) We collected experiences and mapped materials, wall solutions and reference projects. 2) We analyzed and tested – set performance requirements, simulated moisture/energy and verified with measurements in lab and test houses. 3) We took the step to reality with pilot constructions at industrial partners, followed up with measurements, and disseminated lessons learned. The approach provided fast loops between research and industry.
