Baca County, CO Insulation Payback
Baca County attic insulation, by the numbers
Baca County, Colorado is zone 4 under DOE's climate map (Mixed-Dry), which means a wide swing between a hot dry summer and a cold winter. An uninsulated attic there should be built up to R-60. Going from R-2 to the recommended R-60 costs roughly $3,480 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 2.2 years at an estimated $1,605/year saved. Topping up the attic pays for itself fast here.
The breakdown behind the number
Split it out and it's roughly $1,448 a year on the heating side, $157 on cooling. By estimated insulation savings, Baca County lands in the 60th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Baca County comes in 47th by savings. Colorado averages $2,043/year across the counties tracked here; Baca County comes in 21% lower.
Where these numbers come from
Baca County's climate figures — 5,415 heating and 979 cooling degree days a year — are read from SPRINGFIELD COMANCHE, CO US, 4.3 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Baca County in the 60th percentile of this 3,162-county dataset. One local detail the R-value alone won't tell you: Baca County sits in moisture regime B (dry), which can affect the vapor-barrier choice.
Already have some insulation?
A shallower starting point changes the math: with R-11 already down, only the gap to R-49 needs filling, at roughly $2,280 for an estimated $234/year saved (~9.7-year payback). Call this borderline rather than a clear win.
Getting it done in Baca County
Get more than one quote before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth asking upfront given Baca County's estimated $1,605/year on the line.
Where these figures come from
Baca County's R-60 target and its degree-day figures both come from named federal sources - see the methodology guide for exactly which ones. The guide to what R-value actually means explains why R-60 is the target here specifically.
