Anchorage's climate zone, in plain terms
Anchorage, AK runs a January average near 14°F and climbs to about 58°F by July, a swing that adds up to roughly 10,764 heating degree days most winters, with 5 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Anchorage, separate from anything a brochure claims.
Zone 7's requirement is the floor; Anchorage's specific load is what tells you whether beating that floor is worth the extra cost.

Ask specifically about design pressure and impact rating for Anchorage, not just energy performance, if either risk rating comes back on the high side.
