Butler County, OH Insulation Payback
Butler County, OH: what topping up your attic actually costs
DOE classifies Butler County as climate zone 5, cold — a real winter that drives most of the annual energy bill here. 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 2.3 years at an estimated $1,538/year saved. That's about as fast as attic paybacks get.
The breakdown behind the number
The estimated savings split roughly $1,367/year heating, $171/year cooling. Out of every 100 US counties tracked here, Butler County's savings potential beats roughly 55 of them. Within zone 5 specifically, it ranks 705th of 745 counties by estimated savings. Ohio averages $1,669/year across the counties tracked here; Butler County comes in 8% lower.
The climate data behind this
Butler County's climate figures — 5,111 heating and 1,067 cooling degree days a year — are read from HAMILTON BUTLER CO RGNL AP, OH US, 5.6 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Butler County sits at the 56th percentile nationally. Butler County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.
If the attic isn't bare
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 $224/year saved (~10.2-year payback). This one is a genuine toss-up, not a clear yes.

Nothing here is a guess
Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-60 is the target here specifically.
