Chase County, NE Insulation Payback
Chase County, NE: what topping up your attic actually costs
Chase County sits in IECC climate zone 5 (Cold) — a real winter that drives most of the annual energy bill here. For a currently uninsulated attic, DOE and ENERGY STAR recommend building 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 1.9 years at an estimated $1,829/year saved. That's about as fast as attic paybacks get.
Heating vs. cooling in Chase County
The estimated savings split roughly $1,686/year heating, $144/year cooling. Out of every 100 US counties tracked here, Chase County's savings potential beats roughly 74 of them. Within zone 5 specifically, it ranks 246th of 745 counties by estimated savings. Nebraska averages $1,872/year across the counties tracked here; Chase County comes in 2% lower.
The climate data behind this
The heating and cooling degree days behind this estimate — 6,305 HDD and 894 CDD (base 65°F, 1991-2020 normals) — come from IMPERIAL, NE US, the nearest NOAA station with published normals, 2.7 miles from Chase County's center. That combined heating-and-cooling load ranks Chase County 789th nationally by total degree days — the 75th percentile. Chase County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
Already have some insulation?
If Chase 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 $267/year — payback about 8.5 years. This one is a genuine toss-up, not a clear yes.
