Eu Energy Label Dataset Integration Key Data: Dataset Structure and Field Coverage

The key is a credential for EU EPREL - European Product Registry for Energy Labelling, the European Commission's mandatory registry of every energy-labelled model placed on the EU market. Suppliers must register before placing a product on sale, which makes EPREL the authoritative EU-wide master list of regulated models: 33 product groups spanning household appliances (washing machines, washer-dryers, dishwashers, household refrigerating appliances, tumble dryers, domestic ovens, range hoods, air conditioners, lamps, electronic displays), heating products, tyres and smartphones.

Coverage at verification was substantial in every major group: 55,757 refrigerating appliances (2019 group), 32,523 air conditioners, 27,231 domestic ovens, 23,178 household washing machines and 14,227 dishwashers observed live. Each record carries eprelRegistrationNumber, supplierOrTrademark, modelIdentifier, energyClass on the rescaled A-G scale, energyEfficiencyIndex, per-cycle consumption figures (energyConsPer100Cycle, energyConsPerCycle), capacity, dimensions, noise class, market availability dates and EU-representative contact details.

On Datadory's 10-point rubric the source scores 9, against a catalog-wide average of 7.81 across all 1,744 datasets. It is one of only four official-API sources among the 14 primary household-appliances datasets Datadory catalogs.

The issuance flow is administrative rather than technical - five steps, and none of them involves payment:

No - the key matters for sustained programmatic use, while three lighter routes work without it. The distinction decides what you can ship before your declaration clears:

A comparison product needs the label arithmetic plus the identifiers that make rows joinable, and EPREL ships both as first-class fields:

• Label core: energyClass (for example A), energyClassRange (the scale variant such as A_G for rescaled labels), and energyEfficiencyIndex (52 on the verified sample row) - the index from which the class is derived.
• Consumption: energyConsPer100Cycle (48 kWh on washing machines, washer-dryers and dishwashers) and energyConsPerCycle (0.473 kWh), plus waterCons per cycle.
• Capacity and physics: ratedCapacity (8 kg laundry or place settings), spinSpeedRated (1,360 rpm), moistureRated (44% remaining moisture) and programmeDurationRated (218 minutes).
• Identity and lifecycle: eprelRegistrationNumber (352460), implementingAct (EU_2019_2014), onMarketStartDate, firstPublicationDate and registration status.
• Market scope: modelAvailabilityInCountries, which carries ISO codes including XI for Northern Ireland - the post-Brexit flag that tells you whether a registered model may appear in the UK market.

Field definitions are recorded as verified in Datadory's catalog, one of the 85.7% of catalog-wide datasets with confirmed field semantics. The sample row behind those numbers is LG Electronics GC3V708S2, registration 352460, an 8 kg A-class free-standing washer.

The declared-versus-measured split is the one worth designing around: EPREL publishes what suppliers declare under the label rules, Pecan Street publishes what meters record in real homes, and Topten sits between them as an editorial filter on the declared universe. That head-to-head is worked through on the dedicated vs Pecan Street Dataport - High-Resolution Household Energy & Water comparison.

Three workflows recur among the teams that clear the declaration step:

Researchers extend the same registry into energy analysis. DESNZ's Energy Consumption in the UK (ECUK) publication tracks domestic appliance end uses annually from 1970 under OGL v3.0, and CEDA's UK-DALE archive supplies ~6 s appliance-level power for five London homes under commercial delivery terms-4.0 - measured consumption against which declared label figures can be sanity-checked. The recipes run on the market researchers page for sizing workflows and on the industry hub for the full stack.
