Adams County, ND Insulation Payback
Attic insulation payback for Adams County, ND
Adams County, North Dakota is zone 6 under DOE's climate map (Cold), which means cold enough that heating, not cooling, is what decides the bill. 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 1.5 years at an estimated $2,363/year saved. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $2,301/year comes from reduced heating and $62/year from reduced cooling load through the ceiling. Adams County beats 95% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 459 counties DOE places in zone 6, Adams County ranks 55th. Against North Dakota's own average of $2,496/year, Adams County runs 5% below that.
Where these numbers come from
NOAA's HETTINGER MUNI AP, ND US station, 8.2 miles from Adams County, supplies the 8,604 HDD and 386 CDD this estimate runs on. That combined heating-and-cooling load ranks Adams County 166th nationally by total degree days — the 95th percentile. DOE also classifies Adams County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
The smaller top-up scenario
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $345/year saved — roughly 6.6 years to break even. Topping up the attic pays for itself here.
