Something to consider here is the difference between a predictable expense and a variable expense. That 10% is rolled into the mortgage over decades and is a stable, predictable expense that results in an incredibly comfortable home (I cannot overstate how comfortable efficiency homes are). Versus the variability of annual energy expenses over time.

Really what needs to happen is factoring in energy efficiency into home value.

The US has a Passive House standard, the above commenter used the German spelling, that is much better aligned with US climate zones. Getting your home Passive House Certified is likely a bit over rated, like many certifications unless they open up funding.

You can absolutely build a Passive House without getting it certified which is totally worth is.

That being said, there are freaking excellent green building experts in Vermont with loads of experience who can guide you on what approach is right for you.
