Pocahontas County, IA Insulation Payback
Attic insulation payback for Pocahontas County, IA
Pocahontas County sits in IECC climate zone 6 (Cold) — cold enough that heating, not cooling, is what decides the bill. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-60. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $2,090 a year in heating and cooling — a payback around 1.7 years. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Pocahontas County
Of that, about $1,964/year comes from reduced heating and $127/year from reduced cooling load through the ceiling. Pocahontas County beats 86% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 459 counties DOE places in zone 6, Pocahontas County ranks 304th. Against Iowa's own average of $1,985/year, Pocahontas County runs 5% above that.
Where these numbers come from
Pocahontas County's climate figures — 7,344 heating and 789 cooling degree days a year — are read from POCAHONTAS, IA US, 0.9 miles away, NOAA's nearest 1991-2020 normals station. That combined heating-and-cooling load ranks Pocahontas County 397th nationally by total degree days — the 87th percentile. DOE also classifies Pocahontas 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 $305/year saved — roughly 7.5 years to break even. Topping up the attic pays for itself here.
