TIL: the existence of the Norwegian Powerhouse standard for building development.
I'll quote the main definition from the document defining it:
"A Powerhouse shall during its lifetime produce more renewable energy than it uses for materials,
production, operation, renovation and demolition."
That's a hell of a standard, and apparently there's actually buildings being built to it: https://www.treehugger.com/green-architecture/svart-gorgeous-hotel-snohetta-will-meet-worlds-toughest-energy-standard.html
