Bottineau County, ND Insulation Payback
Bottineau County, ND: what topping up your attic actually costs
Bottineau County, North Dakota is zone 7 under DOE's climate map (Very Cold), which means winters long and harsh enough that heating is essentially the entire equation. An uninsulated attic there should be built up to R-60. For an attic around 1,000 square feet, closing the gap from R-2 to R-60 costs around $3,480 and saves an estimated $2,580 a year — payback in roughly 1.3 years. That's about as fast as attic paybacks get.
The breakdown behind the number
The estimated savings split roughly $2,514/year heating, $67/year cooling. Out of every 100 US counties tracked here, Bottineau County's savings potential beats roughly 98 of them. Within zone 7 specifically, it ranks 47th of 120 counties by estimated savings. North Dakota averages $2,496/year across the counties tracked here; Bottineau County comes in 3% higher.
Where these numbers come from
NOAA's WESTHOPE, ND US station, 11.7 miles from Bottineau County, supplies the 9,401 HDD and 416 CDD this estimate runs on. By total degree days, Bottineau County sits at the 98th percentile nationally.
Already have some insulation?
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $376/year saved — roughly 6.1 years to break even. That is a solid payback as home upgrades go.
