Sparks's climate zone, in plain terms
Reno, NV runs a January average near 37°F and climbs to about 74°F by July, a swing that adds up to roughly 4,878 heating degree days most winters, with 706 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Sparks, separate from anything a brochure claims.
Zone 5B's requirement is the floor; Sparks's specific load is what tells you whether beating that floor is worth the extra cost.
