Archibiome framework uses engineered living materials to turn building surfaces into carbon-capturing, self-healing systems

A new perspective article in Frontiers in Systems Biology proposes the archibiome, a framework for treating the microbial life inside buildings as a designable system. Instead of seeing indoor microbiomes as accidental, the authors argue that engineered living materials can intentionally shape microbial communities to perform functions like carbon sequestration, pollutant degradation, and self-healing of building surfaces. The article covers two research projects: ARCHI-SKIN, which uses a fungus to create self-regenerating protective coatings, and REMEDY, which develops living inks for architectural surfaces. The authors also flag open questions around regulatory approval, long-term stability, and public acceptance. Reported performance numbers, such as 15 kg CO2 captured per 10 square meters per year, are still early-stage and need field validation.

Interesting angle. The article frames indoor microbes as something you can design for, not just whatever shows up. The carbon sequestration numbers for the REMEDY ink are still early stage, 15 kg CO2 per 10 m2 per year, which is tiny next to building emissions, but the self-healing and VOC side could matter more.

The maintenance angle is what catches my eye. Self-regenerating coatings that cut material replacement could reduce embodied carbon over a building's life, but the article does not give payback data or real-world durability. Lab performance and facade performance are different things.

Regulation is going to decide whether this stays in journals or reaches sites. The piece mentions EU and US biosafety rules, but does not get into how living materials would fit procurement or building codes. That gap matters more than the biology right now.

As someone focused on retrofits, I want to know how this behaves on existing surfaces. New facades can be designed around living coatings, but most buildings are already standing. Can this be applied to old concrete or brick without ripping things out?

Good read if you want a broad map of engineered living materials. The article is honest that health links are still correlational and that safety testing is unresolved. That is more useful than another hype piece claiming living buildings are here.
