How do I encode the EU A–G energy efficiency class in schema.org?

Use the 'hasEnergyConsumptionDetails' property on your Product with an EnergyConsumptionDetails object. The key property is 'energyEfficiencyScaleMax' set to a EnergyEfficiencyEnumeration URL — for example 'https://schema.org/EUEnergyEfficiencyCategoryA' for Class A or 'https://schema.org/EUEnergyEfficiencyCategoryC' for Class C. Also set 'energyEfficiencyScaleMin' to the lowest grade on the label scale (typically 'https://schema.org/EUEnergyEfficiencyCategoryG') and 'hasEnergyEfficiencyCategory' to the actual rating of your specific product. This structured triple lets AI agents filter by energy class — answering queries like 'A-rated washing machine under £600' or 'most energy-efficient refrigerator.'

Where does annual energy consumption (kWh/year) go in schema.org?

Use 'additionalProperty' with a PropertyValue: { '@type': 'PropertyValue', 'name': 'Annual Energy Consumption', 'value': '157', 'unitCode': 'KWH', 'description': '157 kWh per year (based on standard 220 cycles)' }. This differs from EnergyConsumptionDetails which handles the EU A-G class label — the annual kWh figure is a concrete measured value that AI comparison agents use to answer 'cheapest to run refrigerator under £500.' Include both the EnergyConsumptionDetails class rating and the additionalProperty kWh/year figure for maximum AI agent compatibility across both EU class-filter and cost-to-run queries.

What appliance specifications should I add as additionalProperty?

High-value additionalProperty fields for major appliances: (1) 'Capacity' with unitCode (litres for fridges/dishwashers, kg for washing machines/dryers, cubic feet for US market); (2) 'Annual Energy Consumption' in kWh/year; (3) 'Noise Level' in dB(A); (4) 'Rated Power' in watts (W) or kilowatts (kW); (5) 'Voltage' (230V AC or 120V AC for US); (6) 'Spin Speed' in RPM for washing machines; (7) 'Temperature Range' in Celsius for fridges/freezers; (8) 'Number of Programs' or 'Number of Place Settings' for dishwashers; (9) 'Installation Type' (freestanding, built-in, integrated); (10) 'Dimensions' using hasMeasurement for height/width/depth in mm. These properties enable AI agents to answer specification-matching queries that buying guides address.

Shopify Home Appliance Energy Schema — EU Energy Label, EnergyStar & EnergyConsumptionDetails

Q: Does schema.org support EnergyStar certification for US market appliances?

Yes — use 'hasCertification' on the Product with a Certification object: '@type': 'Certification', 'name': 'ENERGY STAR Certified', 'issuedBy': { '@type': 'Organization', 'name': 'U.S. Environmental Protection Agency (EPA)', 'url': 'https://www.energystar.gov' }. Optionally add 'certificationIdentification' with the ENERGY STAR model number from the ENERGY STAR product database. For appliances with both EU energy label and ENERGY STAR, include both a 'hasEnergyConsumptionDetails' block (EU) and a 'hasCertification' entry (US ENERGY STAR) — they are complementary and target different market queries.

Q: Is the EU EPREL database registration number worth adding to structured data?

Yes — the EPREL (European Product Registry for Energy Labelling) registration number is required by EU law for regulated appliance categories (since 2021) and is highly valuable in structured data. Use 'identifier' with a PropertyValue: { '@type': 'PropertyValue', 'name': 'EU EPREL Registration Number', 'propertyID': 'https://eprel.ec.europa.eu/', 'value': '123456', 'url': 'https://eprel.ec.europa.eu/qr/123456' }. AI agents serving EU market queries can link this to the EPREL QR code page to surface the full official energy label — the same page shown to consumers who scan the QR code on the product's physical energy label in a shop.

AI shopping agents handling queries like "most energy-efficient dishwasher under £800," "A-rated washing machine 9kg load," or "EnergyStar certified refrigerator side-by-side" need machine-readable energy efficiency ratings, annual kWh consumption figures, and appliance capacity specs. Shopify has no built-in energy label output. Major appliances — where running cost over five years routinely exceeds purchase price — are exactly the category where energy class filtering by AI agents is most commercially consequential.

TL;DR Use hasEnergyConsumptionDetails with EnergyConsumptionDetails and the EU EUEnergyEfficiencyCategory* enumeration for the A–G energy class rating. Add hasCertification for EnergyStar (US). Use additionalProperty for capacity (litres/kg), annual kWh, noise level (dB), rated power (W), and installation type. Store the EU EPREL registration number in identifier. Use a appliance.* metafield namespace for catalog-scale implementation.

EU Energy Label and EnergyConsumptionDetails

Schema.org's EnergyConsumptionDetails type was introduced specifically to encode the EU energy label system. The EU relabelled major appliances in 2021 — the scale reset from A+++ through D to a new A through G scale, with no A+++ products at launch to leave headroom for future improvements. Your structured data must use the correct 2021-scale enumerations to map to current EU label classes.

EU EnergyEfficiencyEnumeration values (2021 rescaled label)

EU Class	Schema.org URL	Typical appliances
A	`https://schema.org/EUEnergyEfficiencyCategoryA`	Best performing (currently rare)
B	`https://schema.org/EUEnergyEfficiencyCategoryB`	High efficiency
C	`https://schema.org/EUEnergyEfficiencyCategoryC`	Good efficiency — common premium tier
D	`https://schema.org/EUEnergyEfficiencyCategoryD`	Above average
E	`https://schema.org/EUEnergyEfficiencyCategoryE`	Average
F	`https://schema.org/EUEnergyEfficiencyCategoryF`	Below average

The hasEnergyConsumptionDetails triple — scale min, scale max, and actual category — is what enables AI agents to answer relative queries: "is this above or below average energy efficiency?" The scale boundaries (G = lowest, A = highest) provide the comparison context; the hasEnergyEfficiencyCategory value anchors your product within that scale.

EnergyStar for US Market Appliances

ENERGY STAR is the US equivalent of the EU energy label — a voluntary certification managed by the EPA and DOE, covering refrigerators, dishwashers, washing machines, heat pumps, air conditioners, and over 70 product categories. Unlike the EU's mandatory A-G scale, ENERGY STAR is binary: a product either qualifies or it doesn't. Use hasCertification to express it.

{
  "@type": "Product",
  "name": "FreshKeep 30 French Door Refrigerator — 30 cu ft, ENERGY STAR Certified",

  ]
}

Include the estimated annual operating cost as an additionalProperty — AI comparison agents use this to answer "cheapest to run refrigerator in its size category." Calculate it using the current US average electricity rate ($0.12/kWh as of 2025) and include the rate assumption in the description field so the estimate is transparent.

EU EPREL Registration — Legal Requirement and Structured Data Asset

Since March 2021, all regulated appliance categories sold in the EU must be registered in the EPREL database before going on sale. The EPREL number appears on the physical QR code on the EU energy label. Including it in your structured data serves two purposes: compliance signaling (the product has a valid EPREL registration, meaning it met the 2021 energy regulation requirements) and direct AI agent verification (agents can construct the EPREL verification URL from the registration number).

Appliance category	EU regulation	Mandatory from
Refrigerators / Freezers	EU 2019/2016	1 March 2021
Washing Machines / Washer-Dryers	EU 2019/2014	1 March 2021

5 Common Appliance Energy Schema Mistakes

#	Mistake	Impact	Fix
1	Using old A+++ / A++ class strings after the 2021 EU rescale	A+++ and A++ no longer exist on the 2021 rescaled EU energy label — appliances sold after March 2021 use the A–G scale. Using old class strings in structured data creates confusion in AI agents parsing EU energy class data and may flag as a compliance inconsistency	Use the schema.org `EUEnergyEfficiencyCategory*` enumeration URLs which map to the current A–G scale. Check EPREL for the correct class for each product registered after March 2021
2	Omitting the energy scale boundaries from EnergyConsumptionDetails	Without `energyEfficiencyScaleMin` and `energyEfficiencyScaleMax`, AI agents cannot determine where your product's class falls on the scale — a Class C product looks ambiguous without knowing C is third-best on an A–G scale	Always include all three fields: `hasEnergyEfficiencyCategory` (actual class), `energyEfficiencyScaleMin` (G = worst), `energyEfficiencyScaleMax` (A = best)
3	No annual kWh figure in structured data	AI comparison agents answering "cheapest to run X" need the concrete energy consumption number — the EU class letter only provides a relative ranking within the product category, not an absolute figure for cost-to-run comparisons across categories	Add `additionalProperty` for "Annual Energy Consumption" with the kWh/year value from the EU energy label or EnergyStar test data
4	Missing EPREL registration number for EU-sold appliances	EPREL registration is legally required for most appliances sold in the EU since 2021. Its absence from structured data is a missed trust signal — AI agents surfacing EU market appliances may deprioritize products without EPREL verification link	Add `identifier` PropertyValue with the EPREL registration number and the verification URL (`https://eprel.ec.europa.eu/qr/[number]`)
5	Capacity specified only in product title (e.g., "9kg") without structured additionalProperty	Capacity-filtered queries ("washing machine 8kg or larger," "fridge under 200 litres") rely on structured numerical values for range filtering — title-embedded capacity numbers are inaccessible to AI filter logic	Add `additionalProperty`: `{ 'name': 'Load Capacity', 'value': '9', 'unitCode': 'KGM' }` with the UN/CEFACT unit code so capacity comparisons work numerically

Frequently Asked Questions

How do I encode the EU A–G energy efficiency class?

Use hasEnergyConsumptionDetails with an EnergyConsumptionDetails object. Set hasEnergyEfficiencyCategory to the schema.org enumeration URL for your product's class (e.g., https://schema.org/EUEnergyEfficiencyCategoryC), energyEfficiencyScaleMin to https://schema.org/EUEnergyEfficiencyCategoryG, and energyEfficiencyScaleMax to https://schema.org/EUEnergyEfficiencyCategoryA. This triple provides both the absolute class and the scale context to AI agents. Remember: the 2021 EU rescale eliminated A+++ — use the new A–G scale enumeration values only.

Does schema.org support EnergyStar for US appliances?

Yes — use hasCertification with name: "ENERGY STAR Certified" and issuedBy: { '@type': 'Organization', 'name': 'U.S. Environmental Protection Agency (EPA)' }. Optionally add certificationIdentification with the ENERGY STAR model number. For products with both EU label and EnergyStar (e.g., appliances sold in both markets), include both hasEnergyConsumptionDetails (for EU class) and hasCertification (for ENERGY STAR) — they are complementary. See also Shopify Electronics Hardware Schema for EnergyStar and EU energy label on consumer electronics.

Where does annual kWh consumption go in schema.org?

Use additionalProperty: { '@type': 'PropertyValue', 'name': 'Annual Energy Consumption', 'value': '57', 'unitCode': 'KWH', 'description': '57 kWh/year based on 220 standard cycles' }. The unitCode KWH is the UN/CEFACT code for kilowatt-hour. AI cost-to-run comparison agents use this alongside energy prices to generate annual operating cost estimates — add an estimated cost calculation in the description to preempt that query.

Is the EPREL registration number worth including?

Yes — it's legally required for most EU appliance categories since 2021 and is a strong trust signal. Use identifier PropertyValue with propertyID: 'https://eprel.ec.europa.eu/', the number as the value, and url pointing to https://eprel.ec.europa.eu/qr/[number]. This URL is the same as what appears when a consumer scans the QR code on the physical energy label — AI agents can reference it to surface the official EU energy label for the product.

What appliance specs matter most for AI comparison queries?

Priority by query type: capacity (kg for laundry, litres for fridges, place settings for dishwashers) for size-filter queries; annual kWh for cost-to-run queries; noise level in dB(A) for "quiet" queries; installation type (freestanding vs integrated) for kitchen-fit queries. Add all of these as additionalProperty with correct UN/CEFACT unit codes. For dimensions, use hasMeasurement with QuantitativeValue for height/width/depth in mm. See Shopify Furniture Dimensions Schema for the hasMeasurement pattern.

Is your appliance energy label invisible to AI shopping agents?

CatalogScan audits your Shopify store's structured data and identifies missing EnergyConsumptionDetails, absent EPREL numbers, unstructured capacity specs, and omitted annual kWh figures — ensuring your appliances surface correctly in EU energy class and EnergyStar filter queries.
