# Min/Max Energy Efficiency Class Google Feed Support
Where you might not be using our energy rating service (this would be setup for you as part of this energy rating service which is a chargeable module) you can reach out to to find out more information on this.
This setup enables your Google product feed to include the following optional energy efficiency attributes, which are used to define the range of energy classes available for a product:
- **`min_energy_efficiency_class`**: Indicates the **lowest** energy efficiency class within the product range.
*Example*: `"min_energy_efficiency_class": "D"`
- **`max_energy_efficiency_class`**: Indicates the **highest** energy efficiency class within the product range.
*Example*: `"max_energy_efficiency_class": "A++"`
These values help Google display more detailed energy information for applicable products, improving compliance and visibility in search results.
