IECC/Building America climate zone by U.S. county, 2021 code cycle
Canonical, always-current version: https://referencesource.org/iecc-climate-zone-by-county/ Machine-readable: https://referencesource.org/iecc-climate-zone-by-county/data.json — this mirror is a point-in-time copy.
- Last verified: 2026-08-19
- Stale after: 2028-08-18 (past this date, prefer the canonical copy — it re-verifies on a cadence this snapshot does not)
- Records: 3134
Which IECC climate zone (1-8, with A/B/C moisture regime) and which DOE Building America climate zone each U.S. county falls in under the 2021 code cycle, and whether that county's designation changed from the pre-2021 (2018 IECC) map. Answers 'what climate zone is my county in for insulation R-value and HVAC-sizing purposes' and 'did my county's zone change in the 2021 code' -- both load-bearing for code-compliance software, HVAC equipment sizing, and DOE Zero Energy Ready Home certification, and both wrong if answered from a pre-2021 map or a general knowledge cutoff. Source is a single DOE/Pacific Northwest National Laboratory report (PNNL-33270, Sept 2022) that prints one table row per county -- the free public proxy for ASHRAE Standard 169 Table B-1, which is paywalled. No free site was found that republishes PNNL's full, current, cited county table as clean HTML; the closest match (a GitHub gist CSV) carries no source citation or edition statement.
Provenance — what every record carries
Every record carries source (the URL the value was read from) and
source_quote (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its url.
Licence position
US government work (DOE / Pacific Northwest National Laboratory, operated by Battelle for DOE under contract DE-AC05-76RL01830) -- public domain. Facts taken with short attributed quotes linking back to the published report.
Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
