 Mycelium provides good thermal insulation so there are [[https://archive.is/vXbOe|some projects]] looking to use them to produce insulation, including to replace expanded polystyrene. This might be the easiest drop-in replacement to start out with. Mycelium provides good thermal insulation so there are [[https://archive.is/vXbOe|some projects]] looking to use them to produce insulation, including to replace expanded polystyrene.

 For now, it seems like this stuff is a little further out and we have less of an idea how we'll eventually use it. One thing I've noticed is that mycelium as a building material tends to show up in lots of [[https://www.archdaily.com/1035602/mycelial-hut-yong-ju-lee-architecture|showcase]] [[https://www.expats.cz/czech-news/article/mushroom-kingdom-czechia-unveils-world-s-first-fungi-based-house|projects]], [[https://interestingengineering.com/innovation/students-grow-igloos-from-mushrooms|student demos]], and [[https://parametric-architecture.com/from-fungi-to-foundations-mycelium-in-construction/|temporary outdoor pavilions]], but I've had some trouble finding finished examples like with Mass Timber and Geopolymers.  For now, it seems like this stuff is a little further out and we have less of an idea how we'll eventually use it.
