What zone 5A means for a Highland Park window
Chicago-Naperville-Elgin, IL-IN runs a January average near 24°F and climbs to about 73°F by July, a swing that adds up to roughly 6,366 heating degree days most winters, with 806 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Highland Park, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Highland Park's specific load is what tells you whether beating that floor is worth the extra cost.
