Butler County, NE Insulation Payback
Butler County attic insulation, by the numbers
Butler County, Nebraska is zone 5 under DOE's climate map (Cold), which means a real winter that drives most of the annual energy bill here. 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 1.8 years at an estimated $1,926/year saved. Topping up the attic pays for itself fast here.
Where the savings come from
Split it out and it's roughly $1,776 a year on the heating side, $151 on cooling. By estimated insulation savings, Butler County lands in the 78th percentile nationally. Zone 5 alone covers 745 counties in this dataset, and Butler County comes in 119th by savings. Nebraska averages $1,872/year across the counties tracked here; Butler County comes in 3% higher.
Butler County's actual weather, not a national average
Butler County's climate figures — 6,641 heating and 938 cooling degree days a year — are read from DAVID CITY, NE US, 1.6 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Butler County 627th nationally by total degree days — the 80th percentile. One local detail the R-value alone won't tell you: Butler County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
The smaller top-up scenario
If Butler County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-49. That smaller top-up costs around $2,280 and saves an estimated $281/year — payback about 8.1 years. Call this borderline rather than a clear win.

Where these figures come from
Butler 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.
