Greenwood Village's Climate Data and Its Top-Rated Window Pros
ENERGY STAR groups Arapahoe County into its Northern zone, the U-factor and SHGC target worth checking against any quote you get in Greenwood Village. Below that spec discussion sit 10 installers, their order set by Google rating, since Greenwood Village is outside this site's window license file. A high rating is worth a look, not a finished decision.

What zone 5B means for a Greenwood Village window
Denver-Aurora-Centennial, CO runs a January average near 32°F and climbs to about 73°F by July, a swing that adds up to roughly 5,837 heating degree days most winters, with 675 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Greenwood Village, separate from anything a brochure claims.
Zone 5B's requirement is the floor; Greenwood Village's specific load is what tells you whether beating that floor is worth the extra cost.
