We are searching for topics and funders for the next Longitude Prize. This idea is a draft for discussion about one possible prize focus that we are exploring.
What is the problem? Decarbonising global building stock requires minimally invasive, highly insulating retrofit solutions, yet current materials like petrochemical foams are toxic, flammable, and carbon-intensive. Biological alternatives such as mycelium, bacterial bio-cements, and bio-polymers that could grow into perfectly fitted, low-carbon insulation remain largely unproven at the scale and reliability required for real-world building applications. Why does the solution contribute to solving this? Developing a validated biological insulation material unlocks a globally scalable, minimally invasive retrofit solution, providing the construction and insurance industries with the safety data needed to move from petrochemical dependency towards low-carbon alternatives. Who is the prize awarded to? Awarded to the team that successfully develops a biological or biochemical material that can be injected, sprayed, or grown directly within an existing building envelope to deliver measurable improvements in energy efficiency.

The best prize ideas are developed through extensive research and engagement with experts, stakeholders and people with lived experience of the problems they are focused on. We start with a first draft like the one above – then work to improve, refine and validate our thinking. If you are interested in sharing your expertise, or helping us secure funding for the next Longitude Prize, please reach out.
