While CLT has been certified for 60 years, I don't know how the adhesives they are using are certified for that long. The working life of common industrial adhesives is remarkably short [1]. The key is not just moisture control, but also temperature regulation.

With rigorous humidity and temperature regulation, some adhesives have an as-yet undetermined lifespan. I'm still looking for transportable passive designs without active mechanical assistance that keep humidity at or below 40% and temperature variation to within ±10° C in temperate zones.

There is also CLT without glue, see my other comment. Check https://www.youtube.com/watch?v=4j_UjIshzMc.

"passive designs without active mechanical assistance" - do you mean passive (highly insulated, air tight) designs without mechanical ventilation?

Thanks, I follow Matt so I saw that, but couldn't figure out how they made the exterior wood stand up to the elements.

Yes, PassivHaus or even NetZero type standard, but without an electrically-powered ERV. I don't think it is possible, so I've been looking at minimizing the power requirements.
