Chemung County, NY Insulation Payback
Attic insulation payback for Chemung County, NY
Chemung County sits in IECC climate zone 5 (Cold) — a real winter that drives most of the annual energy bill here. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to 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 1.9 years at an estimated $1,870/year saved. Hard to find a home improvement with a faster payback than this.
Heating vs. cooling in Chemung County
Of that, about $1,779/year comes from reduced heating and $90/year from reduced cooling load through the ceiling. Chemung County beats 76% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Chemung County ranks 177th. Against New York's own average of $1,948/year, Chemung County runs 4% below that.
Where these numbers come from
The heating and cooling degree days behind this estimate — 6,655 HDD and 561 CDD (base 65°F, 1991-2020 normals) — come from ELMIRA, NY US, the nearest NOAA station with published normals, 5.4 miles from Chemung County's center. That combined heating-and-cooling load ranks Chemung County 781st nationally by total degree days — the 75th percentile. DOE also classifies Chemung County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
Already have some insulation?
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $273/year saved — roughly 8.4 years to break even. It is close - the payback only just fits a reasonable timeframe.
