Pasquotank County, NC Insulation Payback
Attic insulation payback for Pasquotank County, NC
Pasquotank County sits in IECC climate zone 3 (Mixed-Humid) — heating load in winter and cooling load in summer, both worth taking seriously here. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-49. For an attic around 1,000 square feet, closing the gap from R-2 to R-49 costs around $2,820 and saves an estimated $1,059 a year — payback in roughly 2.7 years. Hard to find a home improvement with a faster payback than this.
The breakdown behind the number
Of that, about $757/year comes from reduced heating and $302/year from reduced cooling load through the ceiling. Pasquotank County beats 21% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 690 counties DOE places in zone 3, Pasquotank County ranks 338th. Against North Carolina's own average of $1,169/year, Pasquotank County runs 9% below that.
Where these numbers come from
NOAA's ELIZABETH CITY, NC US station, 4.4 miles from Pasquotank County, supplies the 2,852 HDD and 1,895 CDD this estimate runs on. That combined heating-and-cooling load ranks Pasquotank County 2583rd nationally by total degree days — the 18th percentile. DOE also classifies Pasquotank County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.
Already have some insulation?
If Pasquotank County's attic already has 3-4 inches of old insulation (about R-11) rather than bare joists, the recommended target drops to R-38. That smaller top-up costs around $1,620 and saves an estimated $143/year — payback about 11.4 years. It is close - the payback only just fits a reasonable timeframe.
