McKenzie County, ND Insulation Payback
Attic insulation payback for McKenzie County, ND
DOE classifies McKenzie County as climate zone 6, cold — winters that dominate the energy bill, with cooling a minor factor. Its recommended attic R-value for bare joists is 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 1.4 years at an estimated $2,418/year saved. Hard to find a home improvement with a faster payback than this.
Where the savings come from
Of that, about $2,344/year comes from reduced heating and $74/year from reduced cooling load through the ceiling. McKenzie County beats 96% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 459 counties DOE places in zone 6, McKenzie County ranks 28th. Against North Dakota's own average of $2,496/year, McKenzie County runs 3% below that.
The climate data behind this
NOAA's WATFORD CITY, ND US station, 6.8 miles from McKenzie County, supplies the 8,765 HDD and 461 CDD this estimate runs on. By total degree days, McKenzie County sits at the 96th percentile nationally. DOE also classifies McKenzie County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
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 $353/year saved (~6.5-year payback). Topping up the attic pays for itself here.
