I meant the extra investment to meet the codes.

All new housing built in Zone 6 of NH are to have continuous insulation. We never did that before. The standard prior to January 1st was R19. We could do that with 2x6 exterior walls... even go further with R21 or R23 or update to spray foam. That can no longer be done, as none of those will be continuous.
So it changes the construction standard that most have become used to.

Energystar 7.0 requires a less than or equal to .22 U-value and an equal to or greater than .17 Solar Heat Gain Coefficient. Not required by NH building code, but required if someone wants to get federal tax deductions for windows after this year. That would limit the options.

We already have extended lead times for windows that slow home building. Now we need to know long before hand what the construction style will be to create the jamb depths for the windows and doors; or the contractor will need to do more on-site work, and in the case of sills... may not be able to.

Code compliance always requires lots more investment, as items that were once just considered upgrades become the norm.
