Low-Carbon Bio-Based Insulation Systems for Rapid Energy-Efficient Building Renovation

constructionTestedTRL 5

Imagine giving an old building a high-tech, eco-friendly winter coat that keeps heat in and carbon out. Instead of using harsh chemicals, this system uses things like mushroom roots and wood fibers to create insulation panels and bricks. It's designed to be snapped into place easily, making it much faster to turn a drafty old house into a modern, energy-saving home.

The business problem

What needed solving

The current deep renovation rate of 1% is too low to meet 2050 climate goals. Existing renovation processes are often too slow, expensive, or rely on high-carbon materials.

The solution

What was built

A portfolio of bio-sourced and recycled components including mycelium insulation, wood fiber panels, low carbon foam, and multifunctional bricks, supported by a numerical database and material passports.

Business applications

Who can put this to work

Construction Materials
any
Target: Insulation and brick manufacturer

If you are a manufacturer dealing with high carbon footprints in production — this project developed bio-sourced materials like grown mycelium and wood fibers that reduce embodied energy and CO2 emissions. This allows you to offer a portfolio of tailored, low-carbon components for the renovation market.

Real Estate Development
enterprise
Target: Social housing provider

If you are a housing provider dealing with the slow 1% deep renovation rate — this project developed an easy-to-install package of envelope components. This helps you reach a neutral energy balance and improve thermal performance by 20% across your building stock.

Waste Management
SME
Target: Construction waste recycler

If you are a recycler dealing with landfill waste from demolition — this project developed a circular economy circuit for recycled raw materials used in sprayed renders. This turns waste streams into valuable inputs for the construction value chain.

Frequently asked

Quick answers

How does this reduce the cost of deep renovation?

Based on available project data, the system focuses on cost-efficient and easy installation of tailored components, which reduces the labor and time typically required for deep renovations.

Can these materials be produced at an industrial scale?

Yes, WP4 is specifically dedicated to the scale-up of materials into usable products such as insulation panels, foams, bricks, and windows.

What intellectual property or licensing is available?

Based on available project data, the project produces a numerical database and material passports to optimize material combinations, though specific licensing terms are not listed.

How does this align with EU building regulations?

The project supports the EU Renovation Wave objective to double the renovation rate by 2030 and targets climate neutrality by 2050.

What is the timeline for implementation?

The project runs from December 2022 to May 2026, with a 42-month core work plan for material development and validation.

Consortium

Who built it

The consortium is heavily industry-driven with a 59% industry ratio, comprising 10 industrial partners (including 4 SMEs) and 6 research organizations across 7 European countries. This strong industrial presence, led by the French CEA, suggests a high focus on commercial viability and manufacturing scalability rather than purely academic research.
