The high cost of comprehensive building envelope retrofits often makes brute-force renewable energy hardware solutions more financially viable than structural reconstruction.

Questions people asked
What are the economic factors in energy retrofitting versus installing brute-force hardware?
Retrofit economics are brutal that way: peeling back an existing building envelope to eliminate thermal bridges, swap rafters, and re-glaze costs real-world construction money, not paper savings.
Which brings the paradox full circle. At German craftsman rates, it is often cheaper to throw €100k of brute-force hardware—massive PV, huge batteries, maybe an ice tank—at an inefficient building than to rebuild the house around the heating system.
It’s physically clumsy, but financially it makes ugly retrofitting math look almost sane.
