Hi @GregorB, the following paper might be of interest. That study also considered a novel controllable insulation technology known as switchable transparent insulation (STI) — which was trialed but never deployed to my knowledge:

And the related modeling documentation (in German) for more background on the techniques used:

Note that this was a modeling exercise and there was no breakdown of housing stocks by type, uptake potentials, and so forth. See also this recent posting on that question. HTH R
