4AIECC climate zone · ENERGY STAR North-Central zone
East Norriton's climate zone, in plain terms
Philadelphia-Camden-Wilmington, PA-NJ-DE-MD runs a January average near 32°F and climbs to about 78°F by July, a swing that adds up to roughly 4,869 heating degree days most winters, with 1,254 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in East Norriton, separate from anything a brochure claims.
Zone 4A's requirement is the floor; East Norriton's specific load is what tells you whether beating that floor is worth the extra cost.
