DOE Compliance Certification Database
Every basic model's filed efficiency (UEF), storage volume, draw pattern and heater type -- the coverage denominator for every model on this site.
- License class
- P — public domain / open US Government work, public domain.
- Attribution
- Not legally required — every figure derived from it still carries a source and date stamp.
- Fetch cadence
- Weekly (manufacturers may file daily; DOE reviews roughly fortnightly)
- Last fetched
- sources/snapshots/doe-ccd.yml (observed_at)
Worth knowing
- The endpoint answers 403 to a non-browser User-Agent, including this project's own contact-email UA -- a documented exception, not a workaround.
- A row is a (basic model x individual model) pair, not a model. The 5,134 rows measured resolve to 2,288 basic models.
