Comment Yes. This is how you keep housing costs down (Score 0, Troll) 123
By nipping in the bud expensive local patchworks of building regs.
"Net zero" hvac, dishwashers, laundry machines, etc don't actually work as well as traditional alternatives, so homes built around these things need to make up the difference somewhere.
And then there's the added compliance cost. Yes it's a good idea to insulate and airseal your house, but if you have to meet a blower door standard or else it's not fit for habitation, then you need to pay people who don't work for free to run the test at a very minimum, and in practice to also chase down any residual air leaks in the construction.
