Wichita County, KS: what topping up your attic actually costs

Wichita County sits in IECC climate zone 5 (Cold) — winters that dominate the energy bill, with cooling a minor factor. 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 $1,682 a year in heating and cooling — a payback around 2.1 years. That's about as fast as attic paybacks get.

The breakdown behind the number

The estimated savings split roughly $1,510/year heating, $171/year cooling. Out of every 100 US counties tracked here, Wichita County's savings potential beats roughly 65 of them. Within zone 5 specifically, it ranks 513th of 745 counties by estimated savings. Kansas averages $1,594/year across the counties tracked here; Wichita County comes in 6% higher.

The climate data behind this

Wichita County's climate figures — 5,649 heating and 1,067 cooling degree days a year — are read from LEOTI, KS US, 1.2 miles away, NOAA's nearest 1991-2020 normals station. Combined heating and cooling load puts Wichita County in the 66th percentile of this 3,162-county dataset. Wichita 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 $245/year saved (~9.3-year payback). This one is a genuine toss-up, not a clear yes.
